The subframe disclosed in Patent Document 1 is formed in a ladder shape with long left and right vertical frames extending over its entire length and multiple cross members connecting the two vertical frames together, making the subframe as a whole a long, large component.

[0005] However, the length of the subframe needs to be changed depending on the overall length of the vehicle on which it is installed. Therefore, for vehicles with different lengths of chassis (chassis frame), it is necessary to manufacture separate long subframes of different lengths accordingly, resulting in low compatibility.

[0006] The present invention focuses on the above-mentioned problems of the prior art and proposes a garbage collection vehicle equipped with a support member that is highly compatible and can be applied to vehicles having chassis frames of various structures. [Means for solving the problem]

The rear support member piece (measuring means installation member) 43 is made by cutting out a single steel plate in an "H" shape. That is, the rear support member piece 43 has rear girders (girders) 95a, 95b that form part of the girders 32a, 32b, and a crosspiece member (connecting portion) 96 is suspended between them. The rear support member piece 43 is made by processing a steel plate and has a flat shape. The rear beams (beams) 95a, 95b are arranged in parallel and connected by a crosspiece (connector) 96. In this embodiment, a single steel plate is cut into an "H" shape, and rear girders (girders) 95a, 95b and crosspiece member (connecting portion) 96 are integral and inseparable.

[0063] The portion of the rear support piece 43 where the crosspiece member (connection portion) 96 is provided is wider than other portions. Therefore, the portion of the rear support piece 43 where the crosspiece member (connection portion) 96 is provided has a wide overall width. When the rear support piece 43 is installed on the chassis 8, the portion of the rear support piece 43 where the crosspiece member (connection portion) 96 is provided protrudes in the width direction from the chassis 8. The rear support member piece 43 also functions as a measuring means installation member, and the connection portion of the rear support member piece 43 with the crosspiece member (connection portion) 96 has a larger area than other portions and functions as a mounting base 130 for the rear weight measuring means 31a, 31b. In this embodiment, the portion of the rear support member piece 43 that can form the mounting base 130 has a wider overall width than other portions, and when the rear support member piece 43 is installed on the chassis 8, the portion where the crosspiece member (connection portion) 96 of the rear support member piece 43 is provided protrudes widthwise from the chassis 8.

[0064] As shown in FIG. 8, mounting holes 131 for joining to the intermediate support member pieces 42 are provided at the tips of the rear girders (girders) 95a, 95b. The mounting table 130 is provided with five mounting holes 131 for mounting the rear weight measuring means 31a and 31b.

[0065] In the rear support member piece 43 employed in this embodiment, the rear girders (girder portions) 95a, 95b and the crosspiece member (connecting portion) 96 are integrally and inseparably formed. That is, in this embodiment, the rear girders (girders) 95a, 95b and the crosspiece member (connecting portion) 96 are integrally joined, and the girder and the connecting portion cannot be separated. For example, as in this embodiment, when the rear girders (girders) 95a, 95b and the crosspiece (connection) 96 are cut out from a single plate, the rear girders (girders) 95a, 95b and the crosspiece (connection) 96 are integrally joined and cannot be separated, making them inseparable. In other words, when the rear girders (girders) 95a, 95b and the crosspiece (connection) 96 are integrally molded, the two are integrally joined and the girders and the connection parts cannot be separated, making it "inseparable between a pair of girders and a connection part."

[0066] Also, even when the rear girders (girders) 95a, 95b and the crosspiece member (connection part) 96 are molded separately and fastened together with a permanent fastening element, the girders and the connection part are joined together and cannot be separated, so "the pair of girders and the connection part cannot be separated." Methods for permanently fastening components include riveting and welding. It is desirable that the rear girders (girders) 95a, 95b and the crosspiece members (connectors) 96 are unable to move relative to each other. From this perspective, it is desirable that the girders and the connectors are integrally molded or welded structures.

[0067] (Support member piece joining structure) As described above, the first support member 25 is composed of four support member pieces 40, 41, 42, and 43, which are connected in series. That is, the leading support member piece 40 and the front support member piece 41 are joined at a first joint 150, the front support member piece 41 and the middle support member piece 42 are joined at a second joint 151, and the middle support member piece 42 and the rear support member piece 43 are joined at a third joint 152. That is, the leading support member piece 40, the front support member piece 41, the middle support member piece 42, and the rear support member piece 43 are joined in series in this order. The four support member pieces 40, 41, 42, and 43 are loosely engaged via connecting member 110 or connecting member 140, or directly, and are joined by fastening screws. The joining structure of each part will be explained below.

[0068] (Joining structure of leading support member piece 40 and front support member piece 41) The leading support member piece 40 and the front support member piece 41 are directly joined at the first joint 150. In this embodiment, the leading end of the front support member piece 41 is inserted into the rear end of the leading support member piece 40, and a screw is inserted into the overlapping portion of the two to connect them. As described above, there are cutouts 38 in part of the top wall 35 and part of the bottom wall 37 at the rear end of the leading support member piece 40, and the entire side walls 36, 36, the central part of the top wall 35, and the central part of the bottom wall 37 form protruding portions 28.

[0069] In this embodiment, the tip end of the front support member piece 41 is inserted into the rear end of the leading support member piece 40. A through-hole 47 that passes through the leading support member piece 40 in the vertical direction communicates with an attachment hole 100 that passes through the front support member piece 41 in the vertical direction, and as shown in Figure 3, a screw 105 is inserted into this communication hole. Furthermore, a through-hole 48 that passes through the leading support member piece 40 in the horizontal direction communicates with an attachment hole 101 that passes through the side walls 70, 71 of the front support member piece 41 in the horizontal direction, and a screw 106 is inserted into this communication hole. The front support member piece 41 is connected to the rear end of the leading support member piece 40 by screws 105 and 106 .

[0070] In this embodiment, the leading end of the front support member piece 41 is inserted into the rear end of the leading support member piece 40, so that a portion of the top wall 35 of the leading support member piece 40 and a top wall 72 of the front support member piece 41 are in surface contact and overlap. Also, a portion of the bottom wall 37 of the leading support member piece 40 and a bottom wall 73 of the front support member piece 41 are in surface contact and overlap. Furthermore, the side walls 36, 36 of the leading support member piece 40 and the side walls 70, 71 of the front support member piece 41 are in surface contact and overlap. Screws 105 and 106 are inserted into a hole that passes through the first joint portion 150 in the vertical direction and a hole that communicates with the first joint portion 150 in the horizontal direction. The leading support piece 40 and the front support piece 41 are directly engaged with each other by inserting the leading end of the front support piece 41 into the rear end of the leading support piece 40, and are further completely connected by screws 105 and 106.

[0071] (Joint structure between front support member piece 41 and middle support member piece 42) Next, with reference to FIG. 7, the joining structure of the front support member piece 41 and the intermediate support member piece 42 will be described. The front support member piece 41 and the intermediate support member piece 42 are connected at the second joint 151 using a connecting member 110. That is, in this embodiment, the connecting member 110 is interposed between the front support member piece 41 and the intermediate support member piece 42, and the front support member piece 41 and the intermediate support member piece 42 are connected via this connecting member 110. In this embodiment, with the front side of the connecting member 110 inserted into the front support piece 41 and the rear side of the connecting member 110 inserted into the opening of the intermediate support piece 42, multiple screws are inserted, and the front support piece 41 and the intermediate support piece 42 are connected by the fastening force of the screws and the fitting force between the front support piece 41 and the intermediate support piece 42 of the connecting member 110. The outer peripheral surface of the front side of the connecting member 110 and the inner surface of the front support piece 41 are in surface contact. The outer peripheral surface of the front side of the connecting member 110 and the inner surface of the intermediate support piece 42 are also in surface contact.

[0072] 7(b), the connecting member 110 has a front insertion portion 111 and a rear insertion portion 112. The cross-sectional shape of the front insertion portion 111 of the connecting member 110 is rectangular, and is similar to the opening at the rear end of the cross-sectional shape of the front support member piece 41. However, the cross-sectional shape of the front insertion portion 111 of the connecting member 110 is slightly smaller than the opening at the rear end of the front support member piece 41.

[0073] The cross-sectional shape of the rear insertion portion 112 of the connecting member 110 is such that the front half thereof is similar to the opening at the front end of the intermediate support member piece 42, but is slightly smaller than the opening at the front end of the intermediate support member piece 42. The rear end side of the rear insertion portion 112 also becomes thinner as it goes further (rearward). The connecting member 110 has a through hole 113 formed on the side surface of the front insertion portion 111. The connecting member 110 also has a through hole 115 formed on the side surface of the rear insertion portion 112. The connecting member 110 also has a through hole 116 formed in the rear insertion portion 112, which passes through in the vertical direction.

[0074] The front insertion portion 111 of the connecting member 110 is inserted into the opening at the rear end of the front support member piece 41. As described above, the cross-sectional shape of the front insertion portion 111 is similar to, and slightly smaller than, the opening at the rear end of the front support member piece 41. Therefore, as shown in Figure 7(c), when the front insertion portion 111 of the connecting member 110 is inserted into the rear end of the front support member piece 41, three faces of the connecting member 110, excluding the bottom face, contact the inner circumferential surface of the rear end of the front support member piece 41. As described above, the rear open end of the front support member piece 41 does not have a bottom wall 73, and this portion is groove-shaped with side walls 70, 71 and a top wall 72. Therefore, when the connecting member 110 is inserted, three surfaces of the connecting member 110, excluding the bottom surface, are in contact with the side walls 70, 71 and the top wall 72 of the front support member piece 41. As shown in Figure 7(c), a screw 120 is inserted into a through hole 113 provided on the side of the front insertion portion 111 of the connecting member 110 and an attachment hole 76 that penetrates the side walls 70, 71 of the front support member piece 41, and the front insertion portion 111 of the connecting member 110 is connected to the end of the front support member piece 41 by the screw 120.

[0075] The rear insertion portion 112 of the connecting member 110 is inserted into the opening at the front end of the intermediate support member piece 42 . As described above, the intermediate support member piece 42 is made by processing a square tube and has a rectangular annular cross-sectional shape, including side walls 85 and 86, a top wall 87, and a bottom wall 88. As described above, the cross-sectional shape of the front half of the rear insertion portion 112 is similar to, but slightly smaller than, the opening at the front end of the intermediate support member piece 42. Therefore, as shown in Figures 7(d) and 7(e), when the rear insertion portion 112 of the connecting member 110 is inserted into the front end of the intermediate support member piece 42, the entire outer circumferential surface of the connecting member 110 contacts the inner circumferential surface of the front end of the intermediate support member piece 42. Then, as shown in Figure 7(d), a screw 120 is inserted into a through hole 91 penetrating the side walls 85, 86 of the intermediate support member piece 42 and into a through hole 115 provided on the side of the rear insertion portion 112 of the connecting member 110, and the rear insertion portion 112 of the connecting member 110 is connected to the front end portion of the intermediate support member piece 42 by the screw 120.

[0076] In this embodiment, a protruding piece 75 protrudes from the rear end of the front support piece 41. The protruding piece 75 is an extension of the top wall 72 of the front support piece 41. When the front side of the connecting member 110 is inserted into the front support piece 41 and the rear side of the connecting member 110 is inserted into the opening of the intermediate support piece 42, the protruding piece 75 of the front support piece 41 rests on the top wall 87 of the intermediate support piece 42 and comes into contact with the top wall 87 of the intermediate support piece 42.

[0077] As shown in Figure 7(e), a screw 122 is inserted through the mounting hole 77 provided in the protruding piece 75, the through hole 90 penetrating the top wall 87 and the bottom wall 88 of the intermediate support member piece 42, and the through hole 116 penetrating vertically provided in the rear insertion portion 112 of the connecting member 110, and the rear insertion portion 112 of the connecting member 110 is also connected to the front end portion of the intermediate support member piece 42 by the screw 122. That is, one of the support member pieces (front support member piece 41) has a protruding piece 75 protruding from its end, and this protruding piece 75 is in face contact with and overlaps the other support member piece (intermediate support member piece 42), and a screw 122 is inserted into this overlapping portion, and the rear insertion portion 112 of the connecting member 110 is also connected to the front end portion of the intermediate support member piece 42 by this screw 122.

[0078] To summarize, the front insertion portion 111 of the connecting member 110 is inserted into the opening at the rear end of the front support member piece 41, so that in the front half of the second joint 151, the side walls 70, 71 of the front support member piece 41 and the front insertion portion 111 of the connecting member 110 overlap laterally, and a screw 120 is inserted into the overlapping portion to fasten them together. Furthermore, since the front insertion portion 111 of the connecting member 110 is inserted into the opening at the rear end of the front support member piece 41, in the front half of the second joint portion 151, the top wall 72 of the front support member piece 41, the front insertion portion 111 of the connecting member 110, and the bottom wall 73 of the front support member piece 41 overlap in the vertical direction.

[0079] In addition, the rear insertion portion 112 of the connecting member 110 is inserted into the opening at the front end of the intermediate support member piece 42, so that in the rear half of the second joint portion 151, the side walls 85, 86 of the intermediate support member piece 42 and the rear insertion portion 112 of the connecting member 110 overlap laterally, and a screw 121 is inserted into the overlapping portion to fasten them together. Furthermore, the protruding piece 75 of the front support member piece 41, the intermediate support member piece 42, and the rear insertion portion 112 of the connecting member 110 overlap, and a screw 122 is inserted into the overlapping portion to fasten them together.

[0080] The front insertion portion 111 of the connecting member 110 is inserted into the opening at the rear end of the front support member piece 41, so that in the front half of the second joint portion 151, the front support member piece 41 and the connecting member 110 engage with each other and are further completely connected by the screw 120. In addition, the rear insertion portion 112 of the connecting member 110 is inserted into the opening at the front end of the intermediate support member piece 42, so that in the rear half of the second joint portion 151, the connecting member 110 and the intermediate support member piece 42 engage with each other and are further completely connected by screws 121 and 122. In this manner, the front support member piece 41 and the middle support member piece 42 are engaged with each other via the connecting member 110 and are further completely connected by the screws 120, 121, and 122.

[0081] Although the rear end of the front support piece 41 employed in this embodiment has a special shape, the present invention is not limited to this configuration. For example, in the above embodiment, the rear end of the front support piece 41 lacks the bottom wall 73, but it may instead be a square tube having the bottom wall 73. It may also be cylindrical or plate-shaped.

[0082] The connecting member 110 employed in this embodiment has a special shape as described above, but the shape of the connecting member interposed between the front support member piece 41 and the intermediate support member piece 42 is not limited to this embodiment. For example, the connecting member may be a round bar or a square bar. The connecting member may be a square tube or a groove. The connecting member may be a circular tube. It is desirable that the connecting member has a tapered tip, but the tip and the middle may have the same cross-sectional shape. The connecting member may also be a simple plate. It is desirable that the connecting portion seat be able to be fitted into at least one of the front support member piece 41 or the intermediate support member piece 42.

[0083] (Joining structure of intermediate support member piece 42 and rear support member piece 43) Next, the joining structure of the intermediate support member piece 42 and the rear support member piece 43 will be described with reference to FIG. The intermediate support member piece 42 and the rear support member piece 43 are connected at the third joint 152 using a connecting member 140. That is, in this embodiment, the connecting member 140 is interposed between the intermediate support member piece 42 and the rear support member piece 43, and the intermediate support member piece 42 and the rear support member piece 43 are connected via this connecting member 140. The connecting member 140 is a plate-shaped member and is provided with a plurality of mounting holes 156. In this embodiment, the front side of the connecting member 140 is inserted into the opening at the rear end of the intermediate support piece 42, and the rear side of the connecting member 140 is placed on top of the rear support piece 43. Then, a plurality of screws 160, 161 are inserted through the connecting member 140, and the front support piece 41 and the intermediate support piece 42 are connected by the fastening force of the screws 160, 161 and the fitting force of the connecting member 140 with the intermediate support piece 42. That is, in this embodiment, the front half of the connecting member 140 is inserted into the rear end of the intermediate support member piece 42, and a screw 160 is inserted into the overlapping portion of the two to connect them together. In this way, the front side of the connecting member 140 is inserted into the opening at the rear end of the intermediate support member piece 42, and the intermediate support member piece 42 and the connecting member 140 are engaged with each other, and further completely connected by the screw 160. The rear half of the connecting member 140 is placed on the rear support member piece 43, and a screw 161 is inserted into the overlapping portion to connect the two. The front side of the connecting member 140 is in surface contact with the intermediate support member piece 42. The rear half of the connecting member 140 is in surface contact with the rear support member piece 43.

[0084] (Interchangeability of first support member 25) The shape of the chassis 8 varies depending on the vehicle, that is, the overall length and width of the chassis 8 vary depending on the vehicle. The first support member 25 employed in the refuse collection vehicle 1 of this embodiment is made up of four support member pieces 40, 41, 42, and 43 connected by fastening elements such as screws. Therefore, by replacing some of the support member pieces 40, 41, 42, 43, it is possible to accommodate chassis 8 with different overall lengths. Of the support members 40, 41, 42, and 43 employed in this embodiment, the front support member 41 and the rear support member 43 are members to which the weight measuring means 30 and 31 are attached, and have a complex structure. In contrast, the front support member 40 and the middle support member 42 are simple ladder-shaped and easy to manufacture.

[0085] Therefore, for example, by preparing multiple intermediate support member pieces 42 of different lengths and selecting the intermediate support member piece 42 to match the chassis 8, the first support member 25 of this embodiment can be attached to multiple types of vehicles. Furthermore, the leading support member piece 40, the front support member piece 41, and the middle support member piece 42 are attached with screws to crosspiece members 46, 51, 81, 82, and 83. Therefore, by preparing a plurality of crosspiece members 46, 51, 81, 82, and 83 of different lengths and selecting the crosspiece member 46, 51, 81, 82, and 83 to match the chassis 8, the first support member 25 of this embodiment can be attached to a plurality of types of vehicles. The width can also be changed by making the mounting holes of the crosspiece members 46, 51, 81, 82, and 83 elongated and changing the position of the screws.

[0086] (Second support member 26) Next, we will explain the second support member 26. The second support member 26 is made up of a pair of beam members 200a, 200b that extend in the front-to-rear direction of the chassis 8. The beam members 200a, 200b are also called main beams. The beam members 200a and 200b are opposites in left and right. As shown in Figures 9 and 10, each of the beam members 200a and 200b is composed of a main body (three-dimensional structure) 201 and a weight measurement means mounting portion 202. Also, as shown in Figures 9 and 10, a front weight measurement means mounting plate (mounting plate) 240 is provided at the bottom of the main body (three-dimensional structure) 201. The beam members 200a and 200b are arranged in parallel. The following is an explanation.

[0087] (Main body 201) The main body (three-dimensional structure) 201 is made by bending a single plate, and is a groove-shaped member having flanges 210 and 211 at the opening. That is, the cross-sectional shape of the main body (three-dimensional structure) 201 is as shown in FIG. 11, and has vertical wall portions 205 and 206 rising from both sides of the bottom portion 203. As described above, the beam members 200a, 200b are arranged in parallel, and therefore, for convenience of explanation, the vertical wall portion 206 arranged on the inside of the beam members 200a, 200b will be referred to as the inner vertical wall portion 206, and the vertical wall portion 205 arranged on the outside will be referred to as the outer vertical wall portion 205. As described above, the beam members 200a and 200b are opposites, and of the two vertical wall portions 205 and 206, the vertical wall portion 206 located on the inner side is shorter in height than the outer vertical wall portion 205 located on the outer side.

[0088] 9, the upper ends of the two vertical wall portions 205, 206 are both open outward, forming flange portions 210, 211. That is, the main body portion (three-dimensional structure portion) 201 of each of the beam members 200a, 200b has two opposing vertical wall portions 205, 206 rising from both sides of the bottom portion 203, and flange portions 210, 211 that extend away from each other are provided at the upper ends of the respective vertical wall portions 205, 206. The heights of the beam members 200a, 200b vary in the longitudinal direction. The beam members 200a, 200b are long along the front-to-rear direction of the vehicle section 2, but their heights vary in parts. In the beam members 200a, 200b used in this embodiment, as shown in Figures 9 and 10, the central part in the longitudinal direction is high and the front part is slightly lower. The bottom surface between the two is an inclined surface. The height of the beam members 200a, 200b is determined by the shape of the vehicle, etc., and the heights of the beam members 200a, 200b may be uniformly the same.

[0089] The inner vertical wall portion 206 is missing at the rear end of the beam members 200a, 200b. A large, approximately rectangular cutout portion 207 is provided in the outer vertical wall portion 205 at this location. In this embodiment, the cutout portion 207 is tunnel-shaped with an open bottom side, but the top side may also be open. The side surfaces may also be open. An opening may be provided instead of the cutout.

[0090] In the second support member 26 of this embodiment, the upper ends of the vertical wall portions 205, 206 are both open outward, and flange portions 210, 211 are formed. Therefore, the upper trash collection box 20 can be held by the large-area flange portions 210, 211, making it easy to support the trash collection box 20. 9, of the two vertical wall portions 205, 206 of the second support member 26 of this embodiment, the vertical wall portion 206 disposed on the inner side is lower in height than the outer vertical wall portion 205 disposed on the outer side, and therefore the flange portion 211 provided on the inner vertical wall portion 206 is lower in height than the flange portion 210 provided on the outer vertical wall portion 205. This difference in height follows the shape of the bottom surface of the trash collection box 20.

[0091] In this embodiment, the heights of the two vertical wall portions 205, 206 are made different so that the upper portion of the second support member 26 fits along the bottom surface of the trash collection box 20. The heights of the vertical wall portions 205, 206 and the shapes of the flange portions 210, 211 should be changed depending on the trash collection box 20 to be installed, and the two vertical wall portions 205, 206 may be the same.

[0092] In this embodiment, the bottom 203, the two vertical wall portions 205, 206, and the flange portions 210, 211 are formed by bending a single plate, but it is also possible to bend only the bottom 203 and the two vertical wall portions 205, 206 from a single plate, and then attach the flange portions 210, 211 by welding or the like. The second support member 26 may also have a groove shape without a flange portion.

[0093] (Weight measuring means mounting portion 202) The weight measuring means attachment portion 202 is a member attached to the rear end of the main body portion (three-dimensional structure portion) 201 by screws or welding. 12(a) and 12(d), the weight measurement means mounting portion 202 has a bottom plate portion 213 and an inner vertical wall portion 212. The inner vertical wall portion 212 is continuous with the inner vertical wall portion 206 of the main body portion (three-dimensional structure portion) 201 when the weight measurement means mounting portion 202 is attached to the rear end of the main body portion (three-dimensional structure portion) 201. The upper end of the inner vertical wall portion 212 of the weight measuring means mounting portion 202 is formed into a flange portion 215 that opens outward as shown in FIGS. 12(a) and 12(c). As shown in Figure 12, the inner vertical wall portion 212 has an opening 220. As shown in Figures 12(a) and (b), a cover portion 221 is formed on the outer surface of the opening 220. The cover portion 221 protrudes outward from the inner vertical wall portion 212 and covers the top surface and the left and right side surfaces of the opening 220. In this embodiment, the cover portion 221 forms a tunnel-shaped portion 223 on the outside of the inner vertical wall portion 212. The tunnel-shaped portion 223 has an open bottom. The tunnel-shaped portion 223 covers the opening 220 provided in the inner vertical wall portion 212 .

[0094] In this embodiment, an opening 220 is provided in the inner vertical wall portion 212, and the periphery of the opening is protruded to form a tunnel-shaped portion 223. However, instead of the opening 220, a notch with an open bottom or top may be provided, and the periphery of the notch may be protruded to form the tunnel-shaped portion 223. The notch may be open on either the left or right side when viewed from the side.

[0095] In this embodiment, openings 220 or notches are formed at the rear ends of the beam members 200a, 200b by the weight measurement means mounting portion 202. The weight measurement means mounting portion 202 is attached to the openings 220 or notches. As will be described later, a rear detector fixing member (fixing plate) 311 is screwed to the notches or openings 220.

[0096] As shown in FIGS. 12(c) and 12(d), ribs 225a and 225b are provided on the inner surface of the inner vertical wall portion 212, and a boss portion 250 is formed. The ribs 225a, 225b are plates having a certain thickness and protrude from the inner surface of the inner vertical wall portion 212. The ribs 225a, 225b extend vertically. The two ribs 225a, 225b are parallel to each other. The inner surfaces (opposing surfaces) of the two ribs 225a, 225b are smooth. The ribs 225a, 225b are provided with through holes 226a, 226b that extend horizontally in the front-to-rear direction of the chassis 8. The through holes 226a, 226b have different heights. The heights of the through holes 226a, 226b are not limited and may be the same height. In this embodiment, the boss portion 250 formed by the ribs 225a, 225b is rectangular or square. That is, the two ribs 225a, 225b face each other in parallel. The boss portion 250 is not limited to a rectangular or square shape. It is also not limited to a quadrangle. That is, it may be circular. In short, the front shape of the boss portion 250 may be any geometric shape.

[0097] (Front weight measuring means mounting plate 240) The front weight measuring means mounting plate (mounting plate) 240 is a plate on which a joint 230 and a mounting seat 231 are provided. The width of the joint 230 is approximately equal to the width of the bottom 203 of the main body (three-dimensional structure) 201. The width of the mounting seat 231 is wider than the width of the bottom 203 of the main body (three-dimensional structure) 201. That is, as shown in Figures 13 and 17, when the front weight measurement means mounting plate (mounting plate) 240 is attached to the main body (three-dimensional structure) 201 of the beam member 200, a part of the width direction of the mounting seat 231 becomes a protruding portion 216 that protrudes in the width direction from the beam member 200. The joint portion 230 and the mounting seat portion 231 are connected by an inclined portion 232 . The joint portion 230 is provided with a circular opening (opening) 233. The protruding portion 216 of the mounting seat portion 231 is provided with four mounting holes 235.

[0098] 13(b), the upper surface of the front weight measuring means mounting plate (mounting plate) 240, excluding the protruding portion 216, is in contact with the bottom portion 203 of the main body portion (three-dimensional structure portion) 201. However, only a portion of the front weight measuring means mounting plate (mounting plate) 240 is welded to the main body portion (three-dimensional structure portion) 201. In this embodiment, only a portion of the front weight measuring means mounting plate (mounting plate) 240 is located in the front portion of the main body (three-dimensional structure) 201 of the beam member 200, and is welded to the bottom 203 thereof. In this embodiment, as described above, a circular opening (opening) 233 is provided in the joint 230, and the inner wall of the opening 233 is welded to the bottom 203 of the beam member 200, as shown in Figure 13. That is, as shown in Figures 13(b) and (c), a weld buildup 236 is present within the circular opening 233.

[0099] The front weight measuring means mounting plate (mounting plate) 240 is welded (joined) to the main body (three-dimensional structure) 201 only inside the opening (opening) 233, and other parts are not joined (unwelded). That is, only the inner portion of the opening 233 of the front weight measurement means attachment plate (attachment plate) 240 is welded and cannot be separated from the main body (three-dimensional structure) 201. The opening 233 portion of the front weight measurement means attachment plate (attachment plate) 240 is integrated with the main body (three-dimensional structure) 201. The front weight measuring means mounting plate (mounting plate) 240 is in contact with the bottom 203 of the main body (three-dimensional structure) 201 at areas other than the inside of the opening 233, but is not welded to the main body (three-dimensional structure) 201. That is, most of the front weight measuring means mounting plate (mounting plate) 240 is not joined (not welded) to the main body (three-dimensional structure) 201, and therefore will bend when a strong force is applied. In this embodiment, the non-jointed (non-welded) portion of the front weight measuring means mounting plate (mounting plate) 240 is in contact with the bottom 203 of the main body portion (three-dimensional structure portion) 201, but the non-jointed (non-welded) portion may be separated from the bottom 203 of the main body portion (three-dimensional structure portion) 201. That is, in the above-described embodiment, the upper surface of the protruding portion 216 is in contact with the bottom 203 of the main body portion (three-dimensional structure portion) 201, except for the welded portion, but some parts may be separated from the main body portion (three-dimensional structure portion) 201.

[0100] In this embodiment, the inside of the circular opening 233 is welded, but the shape of the opening is arbitrary, and it may be triangular or rectangular. However, in order to prevent stress concentration, it is desirable that the joints be curved, and that the shape of the openings have curved portions such as circles or ellipses. In this embodiment, stress concentration is less likely to occur because the welded portions are circular. Also, in this embodiment, welding is performed within the openings 233 provided in the front weight measurement means mounting plate (mounting plate) 240, so the padding 236 is less likely to protrude outward. Therefore, the welded portion is less likely to bulge outward, and the first support member 25 can be placed directly under the front weight measurement means mounting plate (mounting plate) 240.

[0101] In this embodiment, only one end of the front weight measuring means mounting plate (mounting plate) 240 is welded to the main body (three-dimensional structure) 201 of the beam member 200, and the other end is a free end, so that impacts during travel are less likely to be transmitted directly to the front weight measuring means 30, and the effect of protecting the front weight measuring means 30 can be expected. However, the present invention is not limited to this configuration, and both ends or the entire periphery of the front weight measuring means 30 may be welded to the main body (three-dimensional structure) 201. Also, instead of welding, connection with screws may be used. Furthermore, the planar shape of the front weight measuring means mounting plate (mounting plate) 240 is not limited, and it may be a plate with a uniform overall width, or may have a shape without an inclined surface.

[0102] (Weight measurement means 30, 31) The garbage collection vehicle 1 of this embodiment has four weight measuring means 30a, 30b, 31a, and 31b, and the amount of garbage in the garbage collection box 20 can be detected by the weight measuring means 30a, 30b, 31a, and 31b. The weight measuring means 30a, 30b, 31a, 31b employed in the garbage collection vehicle 1 of this embodiment are shear load cells also known as bar or pin types, and have a rod-shaped detection unit 300 and a base 301 connected to the detection unit 300. The weight measuring means 30, 31 are rod-shaped overall, and both the detection unit 300 and the base 301 have a circular cross-sectional shape. There are various types of shear load cells also known as bar or pin types, and some have a square or other cross-sectional shape. Of course, load cells with a square or other cross-sectional shape may also be used.

[0103] In this embodiment, the weight measuring means 30, 31 are attached between the first support member 25 and the second support member 26 via the base fixing member and the detector fixing member. In this embodiment, front weight measuring means 30a and 30b are attached to the front side of the pedestal 6. Also, rear weight measuring means 31a and 31b are attached to the rear side of the pedestal 6. The base fixing member and detector fixing member for attaching the front weight measuring means 30a, 30b are referred to as the front base fixing member 302 and the front detector fixing member 305. The base fixing member and detector fixing member for attaching the rear weight measuring means 31a, 31b are referred to as the rear base fixing member 310 and the rear detector fixing member 311. The following is an explanation.

[0104] (Front base fixing member 302) The front base fixing member 302 has a base plate portion 315 and a support plate portion 316 as shown in FIG. The base plate portion 315 is configured by a substantially rectangular base plate 320. The base plate portion 315 has six mounting holes 322 formed therein.

[0105] The support plate portion 316 is formed by welding rib members 326 to both sides of a main body portion 325 . The main body 325 is a square plate with a circular opening 328 in the center. The rib member 326 is a generally "L"-shaped plate, and has a support plate attachment portion 327 and a ground portion 323. The bottom surface of the ground portion 323 extends long in the axial direction of the opening 328. The length of the bottom surface of the ground portion 323 is considerably longer than the thickness of the main body portion 325. In other words, the bottom surface of the rib member 326 extends front to back in the axial direction of the opening 328 of the main body portion 325, and the length of the bottom surface of the rib member 326 is approximately three to six times the thickness of the main body portion 325.

[0106] The front base fixing member 302 is formed by welding a support plate portion 316 to a base plate portion 315 in an upright position. In this embodiment, the bottom surface of support plate portion 316 is placed on the surface of base plate portion 315, and the joint between the two is welded. In this embodiment, rib members 326 are provided on both side surfaces of support plate portion 316, and the bottoms of these rib members 326 are welded to base plate portion 315. The lower side of rib member 326 is long in the thickness direction of main body portion 325, and therefore exhibits strength against a load in the direction in which main body portion 325 falls.

[0107] (Front detection unit fixing member 305) As shown in FIG. 15, the front detector fixing member 305 has a base plate portion 330 and a support plate portion 331 . The base plate portion 330 is configured by a substantially rectangular base plate 336. The base plate 336 of the base plate portion 330 is provided with four mounting holes 333a, 333b, 333c, and 333d. As shown in FIG. 15(b), the mounting holes 333a, 333b, 333c, and 333d are provided at the four corners of the base plate portion 330, and an imaginary line 335 connecting the centers of these holes forms a rectangle.

[0108] The support plate portion 331 is a member called a "load cell loading metal fitting," and is a plate with one side having an arc shape, with a circular opening 338 provided in the center. The front detector fixing member 305 is formed by welding a support plate portion 331 to a base plate portion 330 in an upright position. In the front detector fixing member 305 employed in this embodiment, the support plate 331 is attached at a position offset from the center of the base plate 330. More specifically, as shown in Figure 15(b), a center line 340 of an opening 338 in the support plate 331 is offset from a center line 341 of the mounting holes 333a, 333b, 333c, and 333d, and the opening 338 is offset from the centers of the mounting holes 333a, 333b, 333c, and 333d. In this embodiment, the opening 338 is also offset from the center of the base plate 330.

[0109] That is, imaginary line 335 connecting the centers of mounting holes 333a, 333b, 333c, and 333d is rectangular. Therefore, imaginary line 342 connecting mounting holes 333a and 333b and imaginary line 343 connecting mounting holes 333c and 333d are parallel to each other, and their center line is the line indicated by number 341 in Figure 15(b). In contrast, center line 340 of opening 338 in support plate portion 331 is parallel to center line 341 of mounting holes 333a, 333b, 333c, and 333d, but the two do not coincide. In this embodiment, center line 340 of opening 338 in support plate portion 331 is closer to imaginary line 342 connecting mounting holes 333a and 333b.

[0110] (Mounting structure of front weight measuring means 30) Next, the mounting structure of the front weight measuring means 30a, 30b will be described with reference to FIGS. In this embodiment, the front weight measuring means 30a, 30b are installed in a position in which their axes are oriented in the front-rear direction of the chassis 8. In this embodiment, the front weight measuring means 30 is attached between the first support member 25 and the second support member 26 via a front base fixing member 302 and a front detector fixing member 305 . That is, as shown in Figures 14(a), (b), and 20, the base side of the front weight measuring means 30 is inserted into the opening 328 of the front base fixing member 302, and one end of the front weight measuring means 30 is supported by the front base fixing member 302. 14, the front weight measuring means 30 is secured by fasteners 350a and 350b attached with its base inserted into the opening 328 of the front base fixing member 302. That is, with the fasteners 350a and 350b engaged with the front weight measuring means 30, the fasteners 350a and 350b are attached with screws (not shown) from the outside of the support plate 316 to secure the front weight measuring means 30. The front weight measuring means 30 has a groove 353 in its base, into which the fasteners 350a and 350b fit.

[0111] As shown in FIGS. 19 and 20, the tip end of the front weight measuring means 30 is inserted into an opening 338 in the support plate portion 316 of the front detector fixing member 305 via a spherical bearing 351 . 14, the base side of the front weight measuring means 30 is inserted into the opening 328 of the front base fixing member 302 to form a lower combination structure 352 in which one end of the front weight measuring means 30 is fixed. In the lower combination structure 352, the base side of the front weight measuring means 30 is supported by the support plate portion 316, and the other end protrudes from the support plate portion 316 in a cantilevered manner. The tip end protruding from the front base fixing member 302 is held by the support plate portion 331 of the front detector fixing member 305 via a spherical bearing 351 .

[0112] In this embodiment, as shown in FIGS. 17, 18, and 20, the lower combination structure 352 is fixed to the storage shelves 67a and 67b of the first support member 25 with screws (not shown). That is, screws (not shown) are inserted into the mounting holes 322 of the front base fixing member 302 and the mounting holes 68 of the storage shelves 67a and 67b, and the lower combination structure 352 is fixed to the storage shelves 67a and 67b of the first support member 25. 17, 18 and 20, the front detector fixing member 305 is fixed to the front weight measuring means mounting plate 240 of the second support member 26 by screws 255. That is, the mounting holes 333a, 333b, 333c, and 333d of the front detector fixing member 305 are aligned with the mounting holes 235 provided in the mounting seat portion 231 of the front weight measuring means mounting plate 240, and the screws 255 are passed through between them to fix them in place. As a result, the front weight measuring means 30 is attached between the first support member 25 and the second support member 26 via the front base fixing member 302 and the front detector fixing member 305 . In this embodiment, a support plate portion 331, referred to as a "load cell load fitting", hangs down from the second support member 26, and the front weight measuring means 30 is inserted into an opening 338 in the support plate portion 331 via a spherical bearing 351.

[0113] (Compatibility of the front detection unit fixing member 305) The front detection unit fixing member 305 used in this embodiment has an opening 338 for attaching the front weight measuring means 30 in an eccentric position, so by changing the mounting posture of the front detection unit fixing member 305, it can accommodate chassis 8 of different widths and garbage collection boxes 20 of different widths. As described above, in the front detection unit fixing member 305 employed in this embodiment, the center line 340 of the opening 338 of the support plate portion 331 is offset from the center line 341 of the mounting holes 333a, 333b, 333c, and 333d, and is closer to the imaginary line 342 connecting the mounting holes 333a and 333b.

[0114] Therefore, when the spacing between the first vertical members 11a, 11b that make up the chassis 8 is narrow, the front detection unit fixing member 305 is attached to the girder members 200a, 200b of the second support member 26 with the mounting holes 333a, 333b facing inward and the mounting holes 333c, 333d facing outward, as shown in Figure 21(a). As described above, the center line 340 of the opening 338 of the support plate portion 331 is closer to the imaginary line 342 connecting the mounting holes 333a, 333b, so the spacing between the openings 338 of the left and right front detection unit fixing members 305 is narrow, making it possible to accommodate chassis 8 with narrow spacing between the first vertical members 11a, 11b.

[0115] Furthermore, as shown in Figure 21(b), if the posture of the front detection unit fixing member 305 is changed by 180 degrees, with the mounting holes 333c and 333d facing inward and the mounting holes 333a and 333b facing outward, the spacing between the openings 338 of the left and right front detection unit fixing members 305 will increase, making it possible to accommodate a chassis 8 with a wide spacing between the first vertical members 11a and 11b.

[0116] (rear base fixing member 310) The structure of the rear base fixing member 310 is basically the same as that of the front base fixing member 302. That is, a support plate portion 420 is provided upright on a base plate portion 315, and an opening 328 is provided in the support plate portion 316. The rear lower combination structure 400 in which the rear base fixing member 310 and the rear weight measuring means 31 are combined is also the same as the front lower combination structure 352 described above.

[0117] (Rear detection unit fixing member 311) 22(b), the rear detection unit fixing member (fixing plate) 311 is a rectangular or square plate with a circular opening 401 in the center. As described above, the rear detection unit fixing member (fixing plate) 311 is rectangular or square, and opposing side surfaces are parallel. Further, screw holes 402 at different heights are provided on the side surface of the rear detector fixing member (fixing plate) 311. As shown in FIG. 22, the rear detector fixing member (fixing plate) 311 is attached to the weight measuring means mounting portion 202 that constitutes the rear end portion of the beam members 200a and 200b. That is, the rear ends of the beam members 200a, 200b are provided with weight measurement means mounting portion 202, and ribs 225a, 225b are provided on the inner surface of the inner vertical wall portion 212, and these ribs 225a, 225b form a boss portion 250. The rear detection unit fixing member (fixing plate) 311 is disposed between the ribs 225a, 225b provided on the inner surface of the inner vertical wall portion 212, and is attached to the ribs 225a, 225b with screws 403. That is, the parallel sides of the rear detection unit fixing member (fixing plate) 311 are fitted into the rectangular boss portion 250 protruding from the inner vertical wall portion 212. As described above, the weight measuring means mounting portion 202 has a tunnel-shaped portion 223 on the outside of the inner vertical wall portion 212, and the outside of the weight measuring means mounting portion 202 is connected to the opening 401 of the rear detection unit fixing member (fixing plate) 311 via this tunnel-shaped portion 223. In this embodiment, the rear detector fixing member (fixing plate) 311 is screwed to the second support member 26. Therefore, the rear detector fixing member (fixing plate) 311 is not heated during installation, and distortion is less likely to occur in the opening 401. Therefore, the rear weight measuring means 31 can be inserted smoothly.

[0118] (Mounting structure of rear weight measuring means 31) In this embodiment, the rear weight measuring means 31a, 31b are installed in a position in which their axes are perpendicular to the front-rear direction of the chassis 8. As described above, the structure of the rear base fixing member 310 is basically the same as that of the front base fixing member 302, and the rear lower combination structure 400 in which the rear base fixing member 310 and the rear weight measuring means 31 are combined is also the same as the front lower combination structure 352. That is, in the lower combination structure 400, the base side of the rear weight measuring means 31 is supported by the support plate portion 420, and the other end side protrudes from the support plate portion 420 in a cantilevered manner.

[0119] 2, 3, and 23, the rear lower combination structure 400 is fixed to the mounting base 130 of the rear support member piece 43 of the first support member 25 with screws (not shown). That is, the rear lower combination structure 400 is attached to the portion of the rear support member piece 43 of the first support member 25 where the crosspiece member (connecting portion) 96 is provided. The tip end of the rear weight measuring means 31 protruding from the lower combination structure 400 is inserted into the opening 401 of the rear detection unit fixing member (fixing plate) 311. The rear weight measuring means 31 is also held by the rear detection unit fixing member (fixing plate) 311 via a spherical bearing 421. As shown in FIG. 23( b ), the lower combined structure 400 is housed in the tunnel-shaped portion 223 of the weight measuring means mounting portion 202 .

[0120] In this embodiment, the rear lower combination structure 400 is fixed to the mounting base 130 of the rear support member piece 43 of the first support member 25 with screws (not shown), as shown in FIGS. As described above, the portion of the rear support member piece 43 that can form the mounting base 130 has a wider overall width than other portions, and when the rear support member piece 43 is installed on the chassis 8, the portion of the rear support member piece 43 where the crosspiece member (connecting portion) 96 is provided protrudes in the width direction from the chassis 8. Therefore, in this embodiment, there is a margin in the width direction at the position where the lower combination structure 400 is installed. Therefore, even if the width of the chassis 8 is slightly different, the weight measuring means 30, 31 can be attached by using the same rear support member piece 43 in combination, and compatibility is high.

[0121] (Operation of garbage collection truck 1) The garbage collection vehicle 1 of this embodiment has a first support member 25 and a second support member 26 placed on a chassis 8, with the garbage collection device 3 placed on top of those, and weight measurement means 30a, 30b, 31a, and 31b installed between the first support member 25 and the second support member 26. Therefore, the weight including the garbage collection device 3 is detected by the weight measurement means 30a, 30b, 31a, and 31b. Therefore, the weight of the garbage can be calculated by subtracting a predetermined value from the sum of the detected weights of the weight measurement means 30a, 30b, 31a, and 31b.

[0122] Furthermore, in this embodiment, the four weight measuring means 30a, 30b, 31a, and 31b are arranged in a well-balanced manner in the front-rear and left-right directions of the vehicle section 2, so that the detected weight is accurate. Furthermore, in this embodiment, the detection units of the front weight measuring means 30a, 30b arranged at the front of the vehicle unit 2 are held by a support plate 331 suspended from a front weight measuring means mounting plate 240 fixed in a cantilevered manner. Therefore, vibrations during travel are damped by the front weight measuring means mounting plate 240 fixed in a cantilevered manner. For example, even if the vehicle unit 2 bounces significantly, the up and down movement is damped and transmitted to the front weight measuring means 30a, 30b, so the front weight measuring means 30a, 30b are not damaged.

[0123] Furthermore, the rear weight measuring means 31a, 31 arranged at the rear of the vehicle section 2 use a rear support member piece 43, the left and right of which are made inseparably integral, as a measuring means installation member. That is, in this embodiment, a lower combination structure 400 is installed on a large area of ​​the rear support member piece 43. More specifically, a base plate portion 315 made of a single plate that grounds the rear weight measuring means 31a, 31 is attached to the rear support member piece 43, which is also made of a single plate. Therefore, the bottom surface of the base plate portion 315, which is made of a single plate that grounds the rear weight measuring means 31a, 31, does not move partially, and problems such as the attachment of the base plate portion 315 becoming loose are unlikely to occur.

[0124] In this embodiment, the first support member 25 is made up of four support member pieces 40, 41, 42, and 43 connected by fastening elements such as screws, and each joint 150, 151, and 152 is combined and joined three-dimensionally, resulting in high rigidity and connection strength.

[0125] (Modification of the support member piece) In the embodiment described above, the end portions of the support member pieces 40, 41, 42 of the first support member 25 are square tubular and have an annular cross-sectional shape. This configuration is highly rigid and is recommended, but the present invention is not limited to this configuration. For example, the end of each support member piece may be groove-shaped. That is, it may be "concave" with only three sides, either the side wall, the top wall, or the bottom wall. It may also be "L"-shaped with two sides, or flat. It is desirable that the cross-sectional shape of the ends of both support member pieces to be connected be ring-shaped or groove-shaped, and that the two be nested and engaged, but if the cross-sectional shape of the end of at least one of the support member pieces is ring-shaped or groove-shaped, a certain degree of rigidity can be ensured.

[0126] In the embodiment described above, the front support member piece 41 and the intermediate support member piece 42 are connected at the second joint 151 via the connecting member 110. The intermediate support member piece 42 and the rear support member piece 43 are connected at the third joint 152 via the connecting member 140. That is, at these locations, a portion of the connecting members 110, 140 overlaps with an end of one of the support member pieces in surface contact, a portion of the connecting member overlaps with an end of the other support member piece, and a screw is inserted into the overlapping portion. That is, in the embodiment described above, the connecting members 110, 140 overlap with both ends of the support member pieces to be connected in surface contact with a portion of the connecting member, and a screw is inserted into the overlapping portion.

[0127] On the other hand, the ends of the leading support member piece 40 and the front support member piece 41 are fitted together at the first joint 150, and a portion of the leading support member piece 40 and a portion of the front support member piece 41 are directly overlapped, with a screw inserted into the overlapping portion. It is desirable to provide a connecting member at the connection point of each support member piece 40, 41, 42, 43, but it is also possible to overlap the ends and connect them with screws or the like, as in the connection structure of the first joint 150 between the leading support member piece 40 and the front support member piece 41. That is, in the above-described embodiment, connecting members 110, 140 are used to connect the front support member piece 41 and the intermediate support member piece 42 and the connecting portion between the intermediate support member piece 42 and the rear support member piece 43, but these portions may be connected without connecting members. Conversely, a connecting member may be interposed between the leading support member piece 40 and the front support member piece 41.

[0128] The connecting member 110 between the front support piece 41 and the intermediate support piece 42 is three-dimensional and has four sides, whereas the connecting member 140 between the intermediate support piece 42 and the rear support piece 43 is plate-shaped and flat. Thus, the shape of the connecting member should be designed according to the object to be connected, and may be frame-shaped or block-shaped with four sides, groove-shaped with three sides, "L"-shaped with two sides, or flat.

[0129] The leading support piece 40 and the front support piece 41 are overlapped with each other in direct surface contact.
