Description

Technical Field

[0001] The present invention relates to the field of garbage trucks, and in particular to a material collection box for a garbage truck and a material collection method. Background Art

[0002] When the existing garbage truck collects materials, its material collection box is usually fixed and the top cover on the top of the material collection box is opened to expose the feed port, and then the material from the unloading device is loaded into the material collection box through the feed port by arranging the unloading port of the unloading device above the feed port.

[0003] For materials with low fluidity and poor compressibility, such as sludge and sticky pulp sifted from kitchen waste, it is not suitable to use a scraper box or a compression box to assist in collecting such materials. When collecting them using the material collection box in the prior art, the materials are easily accumulated near the feed port and cannot fully fill the space inside the material collection box, resulting in underloading.

[0004] Therefore, there is a need for an improved material collection box for a garbage truck and a method for collecting materials, which should solve the above-mentioned problems of material accumulation and underloading of the material collection box. Summary of the invention

[0038] Figure 1 A perspective view showing a material collection box for a garbage truck according to the present invention, Figure 2A and Figure 2B 1 and 2 respectively show a left view and a right view of a material collection box for a garbage truck according to the present invention, Figure 3A and Figure 3B The top views of the material collection box for a garbage truck according to the present invention are shown respectively when the top cover is closed and opened. Referring to the drawings, in general, the material collection box 10 for a garbage truck according to the present invention comprises:

[0039] A box body 100 defining an inner space for collecting materials from the discharge device, the box body 100 comprising a feed port 111 formed through a top wall 110 of the box body 100;

[0040] a top cover 200 attached to the top wall 110 and configured to open and close to expose and seal the feed port 111;

[0041] A plurality of pulleys 300 attached to the bottom wall 120 of the box body 100, the pulleys 300 being configured to leave the body of the garbage truck and reach and slide along a track fixed to the ground or a platform during the material collection box 10 collecting the material; and

[0042] The controller 400 is configured to control the opening and closing of the top cover 200 during the period when the material collecting box 10 collects materials and control the plurality of pulleys 300 to slide along the track so that the feed port 111 moves relative to the discharge device.

[0043] Generally, the box body 100 is generally formed into a rectangular parallelepiped structure, which includes a top wall 110, a bottom wall 120, and a plurality of side walls connected between the top wall 110 and the bottom wall 120, and each wall together encloses an internal space for accommodating materials in the box body 100. It should be noted that the box body of the rectangular parallelepiped structure shown in the figure is a box body commonly used in the market for material collection boxes of garbage trucks, but it does not have to be formed into this structure.

[0044] The feed inlet 111 is formed to penetrate the top 110 of the box body 100, and has, for example, Figure 3BGenerally, when collecting materials, the unloading device is arranged above the material collection box 10 , so that the unloading port of the unloading device is aligned with the feeding port 111 , so that the materials can be loaded into the inner space of the box body 100 through the feeding port 111 .

[0045] Figure 3A and Figure 3B The top views of the material collection box for garbage trucks according to the present invention are shown respectively when the top cover is closed and opened. It can be seen that the top cover 200 may include a first top cover half 210 and a second top cover half 220 arranged side by side along the width direction of the top wall 110, and the two top cover halves may have exactly the same structure, and when the two top cover halves move to the top of the feed port 111 and are close to each other, the feed port 111 is closed, so that the material cannot be loaded into the box body 100 through the feed port 111 from the discharge device; and when the two top cover halves move away from each other to the side and above the feed port 111, the feed port 111 is exposed, so that the material can be loaded into the box body 100 through the feed port 111 from the discharge device.

[0046] Figure 3B The top cover 200 is shown to be opened to the maximum extent to fully expose the feed opening 111, and at this time, the first top cover half 210 and the second top cover half 220 do not extend out of the lateral extension range of the box body 100. Such a design makes it unnecessary to leave additional space required for opening the top cover 200 on both sides of the box body 100. To this end, as measured in the width direction of the top wall 110, the sum of the widths of the first top cover half 210, the second top cover half 220 and the feed opening 111 can be designed to be approximately equal to or less than the width of the top wall 110 of the box body 100, wherein the sum of the widths of the first top cover half 210 and the second top cover half 220 can be slightly larger than the width of the feed opening 111, so that the feed opening 111 can be completely closed when the first top cover half 210 and the second top cover half 220 are closed.

[0047] In order to control the opening and closing of the top cover 200, the material collection box 10 includes a top cover opening and closing assembly. FIG. 4A to FIG. 4E Describe the components of the top cover opening and closing assembly. Among them, Figure 4A Shown along Figure 1 A cross-sectional view taken at section AA in Figure 4B Show Figure 4A A magnified view of region B in FIG. Figure 4C Shown along Figure 1 A cross-sectional view taken at section CC in Figure 4D Show Figure 4C A magnified view of region D in FIG. 1 , and Figure 4E Shown along Figure 4C Cross-sectional view taken at section EE.

[0048] In general, the top cover opening and closing assembly includes:

[0049] A first top cover opening and closing reducer 201a with a first output gear 202a and a second top cover opening and closing reducer 201b with a second output gear 202b, the first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b are arranged on the top wall 110 and are respectively configured to control the rotation direction and speed of the first output gear 202a and the second output gear 202b;

[0050] A first transmission shaft 203a arranged along the length direction of the first top cover half 210 and a second transmission shaft 203b arranged along the length direction of the second top cover half 220;

[0051] a first pair of transmission gears 204a disposed around both ends of the first transmission shaft 203a and fixedly arranged relative to the first transmission shaft 203a, and a second pair of transmission gears 204b disposed around both ends of the second transmission shaft 203b and fixedly arranged relative to the second transmission shaft 203b, wherein one of the first pair of transmission gears 204a is disposed to mesh with the first output gear 202a and one of the second pair of transmission gears 204b is disposed to mesh with the second output gear 202b; and

[0052] A first pair of racks 205a are respectively fixed to the lower ends of the first top cover half 210 in the length direction, and a second pair of racks 205b are respectively fixed to the lower ends of the second top cover half 220 in the length direction, wherein one of the first pair of racks 205a is meshed with one of the first pair of transmission gears 204a, and one of the second pair of racks 205b is meshed with one of the second pair of transmission gears 204b.

[0053] The working principle of the top cover opening and closing assembly is as follows:

[0054] The first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b drive the first output gear 202a and the second output gear 202b to rotate respectively;

[0055] The first output gear 202a and the second output gear 202b respectively drive one of the first pair of transmission gears 204a and the second pair of transmission gears 204b meshing therewith to rotate, and the first transmission shaft 203a and the second transmission shaft 203b rotate accordingly and respectively drive the other of the first pair of transmission gears 204a and the second pair of transmission gears 204b to rotate;

[0056] The first pair of transmission gears 204a and the second pair of transmission gears 204b drive the first pair of racks 205a and the second pair of racks 205b to move laterally respectively, so that the first top cover half 210 and the second top cover half 220 also move laterally.

[0057] Among them, the first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b can be electrically connected and communicatively connected to the controller 400, and the first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b can be controlled by the controller 400 to drive the first output gear 202a and the second output gear 202b to rotate in different directions, and the first top cover half 210 and the second top cover half 220 can be driven to move away from each other to expose the feed port 111 or the first top cover half 210 and the second top cover half 220 can be driven to move toward each other to close the feed port 111.

[0058] It should be noted that the material collection box 10 is usually long, and the top cover 200 also has a large length dimension accordingly. If a top cover opening and closing reducer, a driving gear, a transmission gear, and a rack are only provided at one end of the top cover, the power provided by the top cover opening and closing reducer may not be sufficient to enable the top cover with a large length dimension to complete the opening and closing action. To this end, by providing a pair of transmission gears, a transmission shaft, and a pair of racks for each of the first top cover half 210 and the second top cover half 220, a top cover opening and closing reducer can provide power to both ends of the corresponding top cover half in the length direction at the same time, thereby facilitating the opening and closing of the corresponding top cover half.

[0059] It should also be noted that in the above-mentioned top cover opening and closing assembly, the first pair of racks 205a and the second pair of racks 205b are both arranged to be parallel to the top cover 200, that is, also parallel to the top wall 110 of the box body 100. Therefore, during the opening and closing process of the top cover 200, the first top cover half 210 and the second top cover half 220 only move parallel to the top wall 110 of the box body 100. Compared with the solution in the prior art in which the opening and closing of the top cover may move in the vertical direction relative to the top wall of the box body (for example, the top cover is pivotally connected to the top wall of the box body), the above-mentioned top cover opening and closing assembly will not increase the overall height of the box body 100 during the opening and closing of the top cover 200 in the air, so the requirement for the unloading space is low.

[0060] It should also be noted that in some prior art that use a cylinder to control the opening and closing of the top cover, the size of the top cover and the corresponding size of the feed port are limited by the stroke of the cylinder. In contrast, with the top cover opening and closing assembly described above, the movement of the two top cover halves is driven by an electrically controlled top cover opening and closing reducer, eliminating the stroke limitation of the cylinder, so that the feed port can be designed to any desired size to improve the efficiency of unloading.

[0061] See also Figure 4B and Figure 4EThe material collection box 10 according to the present invention may further include a pair of slide rails 230 arranged on the top wall 110 of the box body 100 and at both ends of the first top cover half 210 and the second top cover half 220 in the length direction and extending parallel to the top wall 110 of the box body 100 (although the figure only shows one slide rail at one end of the first top cover half 210 and the second top cover half 220 in the length direction, in fact, the same slide rail can also be formed at the other end), the pair of slide rails 230 each define a slide groove 231, and the two ends of the first top cover half 210 and the second top cover half 220 in the length direction are respectively accommodated in the slide groove 231.

[0062] like Figure 4E As shown, the slide groove 231 is, for example, formed in a substantially "C" shape. In order to avoid the first cover half 210 and the second cover half 220 from hitting the slide groove 231 during the opening and closing process of the top cover 200 and causing damage to the first cover half 210 and the second cover half 220, it is preferred that the slide groove 231 is made of a flexible material, such as a nylon material.

[0063] In addition, in order to avoid deformation of the slide groove 231 made of flexible material, the pair of slide rails 230 each include a rigid frame 232 surrounding the corresponding slide groove 231, and the rigid frame 232 is fixed to the top wall 110 of the box body 100. For example, the rigid frame 232 can be fixed to the top wall 110 by being threadedly connected to a bracket welded on the top wall 110.

[0064] With the aid of the slide rail 230 and its slide groove 231 , it can be ensured that the first top cover half 210 and the second top cover half 220 always move along the slide groove 231 parallel to the top wall 110 , and when the top cover 200 is closed, the first top cover half 210 and the second top cover half 220 can be accurately aligned.

[0065] Considering that the first top cover half 210 and the second top cover half 220 are usually heavy, if the first top cover half 210 and the second top cover half 220 collide with each other when they are closed or continue to move when they are opened to the maximum extent, the first top cover half 210 and the second top cover half 220 may be damaged. In order to avoid such potential risks, the material collection box 10 according to the present invention may further include a proximity switch that is communicatively connected to the controller 400, and is used to limit the limit position of the movement of the first top cover half 210 and the second top cover half 220. Specifically, Figure 4AIt is shown that the proximity switches 241 and 242 are respectively installed at the lateral ends of the slide rail 230 to limit the maximum extent to which the first top cover half 210 and the second top cover half 220 can be opened. Specifically, the proximity switches 241 and 242 are configured to send a signal to the controller 400 when sensing that the first top cover half 210 and the second top cover half 220 are opened to the expected maximum limit position, so that the controller 400 can send an instruction to the first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b to control the first top cover half 210 and the second top cover half 220 to stop moving. Figure 4A It is also shown that the proximity switch 243 is arranged at a position between the first top cover half 210 and the second top cover half 220. The proximity switch 243 is configured to send a signal to the controller 400 when it senses that the first top cover half 210 and the second top cover half 220 are about to collide with each other, so that the controller 400 can send instructions to the first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b to control the first top cover half 210 and the second top cover half 220 to stop moving.

[0066] A plurality of pulleys 300 are attached to the bottom wall 120 of the box body 100, and specifically, four pulleys 300 are shown in the figures. Existing material collection boxes are usually equipped with pulleys, but these pulleys are only used to facilitate the movement of the material collection box relative to the body of the hooklift during the process of loading and unloading the material collection box by the hooklift, however, during the process of collecting materials, the pulleys are stationary, so that the entire material collection box is stationary during the process of collecting materials.

[0067] In contrast, the plurality of pulleys 300 of the present invention are configured to slide along a given track during the process of collecting materials. Although not shown in the figure, the given track is a pair of tracks that may be laid on the ground or on a platform. To this end, the material collection box 10 according to the present invention may include: Figure 2A The box moving reducer 311 shown, for example, includes two such box moving reducers 311, which are respectively connected to two driving wheels 310 (or front wheels) in the pulley 300, and the other two in the pulley 300 are driven wheels 320 (or rear wheels) not equipped with a reducer. And the controller 400 can be connected to the box moving reducer 311 in communication to send a signal to the box moving reducer 311 to control the driving wheel 310 to slide along a given track (not shown in the figure) or to be stationary relative to the track, so as to drive the box 100 to move back and forth on the track.

[0068] Back to Figure 1 , which schematically shows that the controller 400 is installed in a storage box attached to one side wall of the box body 100, but the present invention is not limited thereto, and the arrangement position of the controller 400 can be adjusted as needed.

[0069] In addition, the material collection box 10 according to the present invention may also include a wireless signal receiver, which can be installed in the storage box of the side wall of the box body 100 together with the controller 400 and communicated with the controller 400. The wireless signal receiver is configured to receive remote signals, such as command signals for opening and closing the top cover 200 issued by an operator using a remote control, an operation panel, a mobile device, etc., and command signals for starting and stopping the movement of the box body (including the direction and distance of the movement). The wireless signal receiver can send the received command signal to the controller 400, and the controller 400 controls the execution of the action of opening and closing the top cover 200 and controls the box body movement reducer 311 to drive the pulley 300 to start and stop the movement of the box body after receiving the signal.

[0070] Although not shown in the figure, the material collecting box 10 according to the present invention may also be equipped with a material level sensor for sensing the material height in the box body 100. The material level sensor is, for example, arranged above the feed port 111 and emits an ultrasonic signal downward to sense the material height thereunder.

[0071] The material collection box 10 according to the present invention may also include a level indicator (not shown in the figure), which is connected to the level sensor. The level indicator is configured to send different indication signals corresponding to different material height ranges sensed by the level sensor. For example, the level indicator may include indicator lights of different colors. Assuming that the height of the box 100 is 1.5m, the level indicator may be configured as follows: if the level sensor senses that the material height below it is less than 0.5m, it indicates that the filling level of the material in the box 100 is low, and the level indicator may light up green; if the level sensor senses that the material height below it is between 0.5m and 1.2m, it indicates that the filling level of the material in the box 100 is medium, and the level indicator may light up yellow; if the level sensor senses that the material height below it exceeds 1.2m, it indicates that the filling level of the material in the box 100 is high (or reaches a critical value), and the level indicator may light up red. The operator can remotely observe the material level indicator to clearly know the filling level of the material in the box 100, so as to respond in time. For example, when the material level indicator lights up red, the operator knows that he should send a command signal as soon as possible to control the movement of the box to continue filling the material at the lower filling level of the material in the box 100. When the material filling level at various locations in the box 100 reaches a higher level (or reaches a critical value), the operator knows that it is not appropriate to continue filling the material into the box 100, but should suspend the unloading of the unloading device, close the top cover 200 and remove the material collection box 10, and, if necessary, use a new material collection box to continue collecting materials.

[0072] Optionally, the controller 400 is communicatively connected to the material level indicator and is configured to: when the material level indicator indicates that the material filling level (material height) somewhere in the box 100 reaches a set critical value, automatically send instructions to the box moving reducer 311 to control multiple pulleys 300 to slide along a given track so that the feed port 111 moves a certain distance relative to the unloading device.

[0073] When the material level indicator indicates that the material filling level (material height) at each location in the box 100 has reached the set critical value, the unloading is stopped and the controller 400 can be further configured to automatically send instructions to the first top cover opening and closing reducer 201a and the second top cover opening and closing reducer 201b to control the top cover 200 to close to close the feed port 111. In addition, if necessary, a new material collection box can be used to continue collecting materials.

[0074] The present invention also provides a method for collecting materials, comprising:

[0075] Providing a material collection box 10 according to the present invention;

[0076] Place the material collection box 10 below the discharge device so that the discharge port of the discharge device is aligned with the feed port 111 of the material collection box 10;

[0077] The controller 400 controls the top cover 200 to open to expose the feed port 111, and the material from the unloading device is loaded into the inner space of the material collecting box 10 through the feed port 111.

[0078] When it is detected that the material filling height at a certain place in the material collecting box 10 reaches a set critical value, the controller 400 controls the plurality of pulleys 300 to slide along the track so that the feed port 111 moves a set distance relative to the discharge device; and

[0079] When it is detected that the material height at each location in the box body 100 reaches the set critical value, the unloading is stopped and the top cover 200 is controlled by the controller 400 to close to seal the feed port 111. In addition, a new material collection box can be used to continue collecting materials if necessary.

[0080] It should be noted that the controller 400 controls the distance that the multiple pulleys 300 slide along the track each time, that is, the set distance that the feed port 111 moves relative to the unloading device each time can be adjusted according to actual needs (such as the length of the feed port 111, the requirement for material filling uniformity, etc.), and each time the multiple pulleys 300 slide along the track, it should be ensured that the feed port 111 is always located below the unloading port of the unloading device during material collection so as to completely load the material from the unloading device into the internal space of the material collection box 10.

[0081] The method for collecting materials according to the present invention is performed by the material collection box 10 according to the present invention, and the aforementioned actions of the various components of the material collection box 10 according to the present invention are all covered within the scope of the method according to the present invention. Through the material collection box for garbage trucks and the method for collecting materials according to the present invention, uniform filling of materials in the material collection box is achieved, especially for materials with low fluidity and poor compressibility, the accumulation of materials near the feed port and the underloading of the material collection box can be avoided. Secondly, since the opening and closing of the top cover and the movement of the material collection box are both electrically controlled, the need for a hydraulic power system, a cylinder and a hydraulic pipeline is eliminated, thereby saving costs, and the electrical control can be remotely controlled by an operator, so it is convenient for the operator to operate. In addition, the movement of the two top cover halves is driven by the electrically controlled top cover opening and closing reducer, eliminating the stroke limit of the cylinder, so that the feed port can be designed to any desired size to improve the efficiency of unloading. Finally, by introducing a material level sensor and a material level indicator, intelligent feeding is achieved, and no operator is required to observe on site during the entire feeding process.
