Description

Technical Field

[0001] This application belongs to the technical field of reducing scales, and particularly relates to a vibration reducing scale. Background Technology

[0002] Vibratory weighing scales using electric vibratory feeders are widely used in industrial production and commercial processes. For example, when bulk materials need to be added according to mass ratios, or before packaging and repackaging such materials, vibratory weighing scales are often used for precise measurement; vibratory weighing scales can also be used for precise weighing in the automatic inspection and sample preparation processes of bulk materials.

[0003] The prerequisite for accurate measurement by a vibration reduction scale is to ensure that the bulk material entering the silo does not leak out uncontrollably.

[0004] However, in related technologies, uncontrolled leakage of material falling onto the feed chute often occurs, leading to inaccurate metering. Utility Model Content

[0005] This application aims to at least partially solve the technical problem of uncontrolled leakage of materials falling onto the feed chute in related technologies. To this end, this application provides a vibration reduction scale.

[0006] This application provides a vibration reduction scale, including:

[0007] The scale body; a vibrator mounted on the scale body; a third bracket mounted on the output end of the vibrator;

[0008] The material guide trough has its inlet side located below the outlet of the scale body and rotatably connected to the third bracket. The material guide trough has a first position where the outlet side is higher than the inlet side and a second position where the outlet side is not higher than the inlet side.

[0009] A support component is installed on the scale body and acts on the guide trough. Under the action of the support component, the guide trough can be located at the first position, and under the action of the gravity of the material, the guide trough can be located at the second position.

[0010] In some embodiments, the support component includes:

[0011] A limiting mechanism is installed on the scale body;

[0012] A support member is disposed below the material guide trough and in contact with the material guide trough, and is located on the side of the material guide trough's rotating shaft closer to the discharge side;

[0013] A first elastic element is disposed within the limiting mechanism and acts on the first elastic element and the limiting mechanism to enable the support member to support the guide groove.

[0014] In some embodiments, the limiting mechanism includes:

[0015] The housing is fixedly connected to the scale body;

[0016] The limiting member, the first elastic member and the limiting member are both disposed inside the housing, the first elastic member is located between the support member and the limiting member and abuts against the limiting member.

[0017] In some embodiments, the limiting member is slidably connected to the housing along the length direction of the first elastic member, and the limiting mechanism further includes:

[0018] The second elastic element acts on the limiting element and the scale body;

[0019] The connector is movably connected to the limiting member along the length direction of the first elastic member, and under the action of the second elastic member, the connector abuts against the second bracket.

[0020] In some embodiments, one side of the limiting member extends through the scale body, and the connecting member is threadedly connected to the side of the limiting member that extends through the scale body.

[0021] In some embodiments, the support member is fixedly connected to the first elastic member; the vibration reduction scale further includes an adjustment mechanism, which is disposed on both sides of the support member, and the adjustment mechanism includes:

[0022] The lead screw passes through the third bracket and contacts the support member;

[0023] The first nut and the second nut are both threaded onto the lead screw and are located on opposite sides of the lead screw, respectively.

[0024] In some embodiments, the pivot is movably disposed within the connecting hole.

[0025] In some embodiments, the vibration reduction scale further includes a counterweight mechanism, the counterweight mechanism comprising:

[0026] A connecting rod is provided along the material conveying direction of the guide trough, and the two ends of the connecting rod are respectively located on both sides of the rotating shaft of the guide trough and are fixedly connected to the guide trough.

[0027] A counterweight is movably connected to the connecting rod along the extension direction of the connecting rod.

[0028] In some embodiments, the guide trough includes a first trough segment and a second trough segment connected together. The first trough segment is connected to the third bracket, and the second trough segment is disposed on the side of the first trough segment away from the rotating shaft. The inclination angle of the second trough segment is greater than the inclination angle of the first trough segment, and the second trough segment is inclined downward when the guide trough is located in the first position.

[0029] In some embodiments, the scale body includes:

[0030] First support;

[0032] The hopper, which functions with the weighing sensor, has the discharge port;

[0033] The second bracket is installed on the hopper, and both the support assembly and the vibrator are installed on the second bracket.

[0034] This utility model has at least the following beneficial effects:

[0035] In related technologies, during the initial feeding stage, the first material fed in, falling from a height, possesses a certain kinetic energy. If it directly impacts the guide chute, it will either rebound or move along the discharge direction of the guide chute, rolling out of it. With this design, when no material is being fed in, the discharge side of the guide chute is higher than the feed side due to the support components, making the guide chute close to the feed trough. This ensures that even if the material rebounds, it will bounce back into the hopper and is less likely to bounce directly outside the vibrating damper. Furthermore, because the discharge side is higher than the feed side, the material cannot move along the discharge direction of the guide chute and roll out of it, thus preventing uncontrolled leakage. When the material accumulated in the hopper is sufficient to press down the guide chute, it will rotate from the first position to the second position. Since the material initially fed into the guide chute has lost kinetic energy, even in the second position, without activating the vibrator, the material initially fed into the guide chute will not be discharged along the guide chute.

[0036] After adopting the vibration reduction scale of this application, there will be no uncontrolled leakage of materials in the initial stage of material feeding, which ensures the measurement accuracy of the vibration reduction scale. After the material accumulates to a certain amount on the guide chute, the guide chute can be rotated to the second position without affecting the normal discharge of materials, thus ensuring the controllable discharge of materials.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0051] In related technologies, the structure of vibration reduction scales can be referenced. Figure 9 As shown, or as shown in the patent with patent publication number CN201434720Y.

[0052] Ore pellets are elliptical in shape, have a high density and good elasticity. When the pellets are weighed using a vibration reducing scale, in the initial stage of the pellets being poured into the silo, the pellets may fall onto the feed chute and be ejected or rolled out along the feed chute, resulting in uncontrolled leakage.

[0053] Therefore, in related technologies, when using a vibration reducing scale, there is a technical problem that materials falling onto the feed chute are prone to uncontrolled leakage.

[0054] This application is described below with reference to the accompanying drawings and specific embodiments:

[0055] This application provides a vibration reduction scale, which can at least partially solve the technical problem of uncontrolled leakage of bulk materials in the hopper of the vibration reduction scale in the related art.

[0056] like Figures 1 to 5 As shown, the vibratory reducing scale 100 includes a scale body 110, a vibrator 120, a third support 130, a guide trough 140, and a support assembly 150. The vibrator 120 is mounted on the scale body 110. The third support 130 is mounted on the output end of the vibrator 120. The feed side 140a of the guide trough 140 is located below the discharge port 113a of the scale body 110 and is rotatably connected to the third support 130. The guide trough 140 has a first position where the discharge side 140b is higher than the feed side 140a and a second position where the discharge side 140b is not higher than the feed side 140a. The support assembly 150 is mounted on the second support 114 and acts on the guide trough 140. Under the action of the support assembly 150, the guide trough 140 can be located in the first position, and under the gravity of the material, the guide trough 140 can be located in the second position.

[0057] When the vibrator 120 is working, it drives the third support 130 to vibrate. The guide trough 140 is installed on the third support 130. The third support 130 supports the guide trough 140. When the third support 130 vibrates, it drives the guide trough 140 to vibrate, causing the material in the guide trough 140 to move.

[0058] The feed side 140a of the guide chute 140 is located below the discharge port 113a, allowing material inside the weighing body 110 to fall into the guide chute 140. The third support 130 supports the guide chute 140, and the feed side 140a of the guide chute 140 is rotatably connected to the third support 130; therefore, the guide chute 140 can rotate. Figure 6As shown, the feed chute 140 can be rotated to a first position where the discharge side 140b is higher than the feed side 140a, or to a second position where the discharge side 140b is not higher than the feed side 140a. The discharge side 140b not being higher than the feed side 140a can mean that the discharge side 140b and the feed side 140a are at the same height, such as... Figure 7 As shown; there are also two other situations where the discharge side 140b is lower than the feed side 140a, such as... Figure 8 As shown.

[0059] The support assembly 150 can apply an upward force to the guide chute 140, so that the guide chute 140 can be located in the first position when no material is loaded or in the initial stage of material loading (when there is less material on the guide chute 140 in the initial stage of material loading). As material continues to be loaded, more and more material is on the guide chute 140, and the force exerted by the material on the guide chute 140 gradually increases. When the force exerted by the material on the guide chute 140 is greater than the force exerted by the support assembly 150 on the guide chute 140, the guide chute 140 will rotate from the first position to the second position.

[0060] In related technologies, during the initial feeding stage, the first material fed in has kinetic energy after falling from a height. If it directly hits the guide chute 140, it will either bounce back or move along the feeding direction of the guide chute 140 and roll out of the guide chute 140. With this design, when no material is being fed, the discharge side 140b of the guide chute 140 is higher than the feed side 140a under the action of the support component 150, making the guide chute 140 close to the feed trough. In this way, even if the material bounces back, it will bounce back into the hopper 113 and is less likely to bounce directly outside the vibration damping scale. In addition, since the discharge side 140b is higher than the feed side 140a, the material cannot move along the feeding direction of the guide chute 140 and roll out of the guide chute 140. Therefore, there will be no problem of uncontrolled leakage of material. When the material accumulated in the hopper 113 is sufficient to press down the guide chute 140, the guide chute 140 will rotate from the first position to the second position. Since the material initially placed on the guide chute 140 has lost its kinetic energy, even if the guide chute 140 is in the second position, the material initially placed on the guide chute 140 will not be discharged along the guide chute 140 without starting the vibrator 120.

[0061] After adopting the vibration reduction scale 100 of this application, there will be no uncontrolled leakage of materials in the initial stage of material feeding, which ensures the metering accuracy of the vibration reduction scale 100. After the material accumulates to a certain amount on the guide chute 140, the guide chute 140 can be rotated to the second position without affecting the normal discharge of materials, thus ensuring the controllable discharge of materials.

[0062] In some embodiments, the weighing body 110 includes a first support 111, a load cell 112, a hopper 113, and a second support 114. The load cell 112 is mounted on the first support 111. The hopper 113 acts on the load cell 112 and has a discharge port 113a. The second support 114 is mounted on the hopper 113, and the support assembly 150 and the vibrator 120 are both mounted on the second support 114.

[0063] A load cell 112 is mounted on a first support 111, and a hopper 113 is mounted on the load cell 112, applying a force to the load cell 112 so that the load cell 112 can weigh the hopper 113, the second support 114 connected thereto, the vibrator 120 mounted on the second support 114, the guide chute 140 mounted on the vibrator 120, and the total weight of the material located in the hopper 113 and the guide chute 140. The mounting and connection relationships of the load cell 112, the hopper 113, and the first support 111 are varied and known to those skilled in the art, and are not limited here. The second support 114 is fixedly connected to the hopper 113 and is used to support the vibrator 120 and the support assembly 150. The vibrator 120 is fixedly connected to the second support 114.

[0064] In some embodiments, the support assembly 150 includes a limiting mechanism 151, a support member 152, and a first elastic member 153. The limiting mechanism 151 is mounted on the scale body 110; the support member 152 is disposed below and in contact with the guide trough 140, and is located on the side of the guide trough 140's rotating shaft 142 near the discharge side 140b; the first elastic member 153 is disposed within the limiting mechanism 151, and acts on the first elastic member 153 and the limiting mechanism 151 to allow the support member 152 to support the guide trough 140.

[0065] It should be noted that in the embodiment where the scale body 110 includes the second support 114, the limiting mechanism 151 is mounted on the second support 114. For example... Figure 5 As shown, the support member 152 is located to the right of the rotating shaft 142 of the guide trough 140. The first elastic member 153 is disposed within the limiting mechanism 151, and the inner wall of the limiting mechanism 151 can limit the first elastic member 153, allowing the first elastic member 153 to extend and retract along its length. One end of the first elastic member 153 abuts against the limiting mechanism 151, and the other end abuts against the support member 152. The support member 152 is disposed below the guide trough 140 and is disposed on the side of the rotating shaft 142 of the guide trough 140 near the discharge side 140b. Under the elastic force of the first elastic member 153, the support member 152 presses against the guide trough 140, applying an upward force to the guide trough 140, allowing the guide trough 140 to rotate around the rotating shaft 142 and be positioned in the first position.

[0066] The first elastic element 153 can be a spring, an elastic rubber block, etc., and is not limited in this application. In some embodiments, the first elastic element 153 is a spring, and the first elastic element 153 is always in a compressed state.

[0067] In some embodiments, the first elastic element 153 is arranged vertically.

[0068] In some embodiments, the limiting mechanism 151 includes a housing 1511 and a limiting member 1512. The housing 1511 is fixedly connected to the scale body 110; the first elastic member 153 and the limiting member 1512 are both disposed within the housing 1511, the first elastic member 153 is located between the support member 152 and the limiting mechanism 151, and abuts against the limiting member 1512.

[0069] It should be noted that in the embodiment where the scale body 110 includes the second support 114, the housing 1511 is fixedly connected to the second support 114. For example... Figure 2 As shown, the support member 152 is located above the limiting member 1512, and the first elastic member 153 is located between the support member 152 and the limiting member 1512, and is located inside the housing 1511. The upper end of the first elastic member 153 abuts against the support member 152, and the lower end of the first elastic member 153 abuts against the limiting member 1512. The housing 1511 limits the first elastic member 153, causing the first elastic member 153 to extend and retract along its length. The limiting member 1512 limits the lower end of the first elastic member 153, thus fixing the lower end of the first elastic member 153.

[0070] In some embodiments, the upper end of the first elastic member 153 is fixedly connected to the support member 152, and the lower end is fixedly connected to the limiting member 1512.

[0071] In some embodiments, the limiting member 1512 is slidably connected to the housing 1511 along the length direction of the first elastic member 153. The limiting mechanism 151 also includes a second elastic member 1513 and a connecting member 1514. The second elastic member 1513 acts on the limiting member 1512 and the scale body 110. The connecting member 1514 is movably connected to the limiting member 1512 along the length direction of the first elastic member 153. Under the action of the second elastic member 1513, the connecting member 1514 abuts against the second bracket 114.

[0072] It should be noted that in the embodiment where the scale body 110 includes a second support 114, the second elastic member 1513 acts on the limiting member 1512 and the second support 114. The limiting member 1512 can slide along the length direction of the first elastic member 153. Along the length direction of the first elastic member 153, the connecting member 1514 is movably connected to the limiting member 1512, that is, along the length direction of the first elastic member 153, the connecting member 1514 can be connected at different positions on the limiting member 1512. Under the action of the second elastic member 1513, the connecting member 1514 abuts against the second support 114, so the position of the connecting member 1514 relative to the second support 114 is fixed. With this design, the second elastic member 1513 applies a force to the limiting member 1512, causing the limiting member 1512 to tend to move towards the first elastic member 153, so that the connecting member 1514 abuts against the second support 114. In this way, the position of the connecting member 1514 on the limiting member 1512 can be adjusted, thereby adjusting the position of the limiting member 1512 relative to the housing 1511, which in turn adjusts the position of the lower end of the first elastic member 153, thereby adjusting the initial compression of the first elastic member 153, and further adjusting the supporting force applied by the support member 152 to the guide groove 140. This allows the initial compression of the first elastic member 153 to be adjusted according to the weight of the guide groove 140, the position of the support member 152, etc., making it easier for users to use the vibration reduction scale 100.

[0073] The limiting member 1512 and the connecting member 1514 can be connected in various ways. In some embodiments, the limiting member 1512 and the connecting member 1514 are connected by a threaded connection. In some embodiments, a plurality of insertion holes are spaced apart on the limiting member 1512 along the length direction of the first elastic member 153, and the connecting member 1514 can be inserted into each insertion hole respectively, thereby realizing the movable connection between the connecting member 1514 and the limiting member 1512.

[0074] In some embodiments, one side of the limiting member 1512 penetrates through the scale body 110, and the connecting member 1514 is threadedly connected to one side of the limiting member 1512 that penetrates through the second bracket 114.

[0075] It should be noted that in the embodiment where the scale body 110 includes the second support 114, one side of the limiting member 1512 penetrates through the second support 114. For example... Figure 3 As shown, the lower end of the limiting member 1512 passes through the second bracket 114 and extends out of the second bracket 114. The connecting member 1514 is located below the second bracket 114 and is threadedly connected to the lower end of the limiting member 1512. With this design, by screwing on the connecting member 1514, the length of the upper side of the limiting member 1512 extending out of the second bracket 114 can be adjusted, thereby adjusting the position of the lower end of the first elastic member 153 and adjusting the initial compression of the first elastic member 153.

[0076] In some embodiments, the connector 1514 is a nut.

[0077] In some embodiments, such as Figure 4 As shown, the support member 152 is fixedly connected to the first elastic member 153. The vibration reduction scale 100 also includes an adjustment mechanism 160, which is disposed on both sides of the support member 152. The adjustment mechanism 160 includes a lead screw 161, a first nut 162, and a second nut 163. The lead screw 161 passes through the third bracket 130 and contacts the support member 152. The first nut 162 and the second nut 163 are both threadedly connected to the lead screw 161 and are located on both sides of the lead screw 161, respectively.

[0078] The support member 152 is fixedly connected to the upper end of the first elastic member 153. Two adjustment mechanisms 160 are provided beside each support assembly 150. The two adjustment mechanisms 160 are spaced apart along the material conveying direction of the guide chute 140. The two adjustment mechanisms 160 are located on both sides of the support member 152 of the support assembly 150, that is, the support member 152 is located between the two adjustment mechanisms 160. Figure 4 As shown, an adjustment mechanism 160 is located on the left side of the support frame, and another adjustment mechanism 160 is located on the right side of the support member 152. The lead screw 161 of the adjustment mechanism 160 passes through the third bracket 130. The lead screw 161 is positioned along the material transmission direction of the guide trough 140, meaning its length is parallel to the material transmission direction. The first nut 162 and the second nut 163 are both connected to the third bracket 130 and are located on opposite sides of the third bracket 130. Tightening the two nuts clamps the third bracket 130. With this design, the position of the lead screw 161 can be adjusted by screwing the first nut 162 and the second nut 163, making the position of the support member 152 adjustable in the material transmission direction of the guide trough 140. This allows the support member 152 to provide support to different parts of the guide trough 140. With this design, the position of the support 152 can be adaptively adjusted according to the different masses of the guide trough 140 and the position of the rotating shaft 142 on the trough 141, so that the guide trough 140 can be smoothly in the first position when it is not carrying material or carrying a small amount of material, which makes it easier for users to use the vibration reducing scale 100.

[0079] In some embodiments, the guide trough 140 includes a trough body 141 and a rotating shaft 142 fixedly disposed on the trough body 141; the third bracket 130 has a connecting hole 132a, and the rotating shaft 142 is disposed in the connecting hole 132a to realize the rotatable connection between the guide trough 140 and the third bracket 130.

[0080] In some embodiments, the feed trough 140 has two rotating shafts 142, which are coaxially arranged and located on both sides of the trough body 141.

[0081] In some embodiments, such as Figure 4 and Figure 5 As shown, the third bracket 130 includes a support plate 131, a first ear plate 132, and a second ear plate 133. Both the first ear plate 132 and the second ear plate 133 are fixedly connected to the support plate 131. The groove 141 of the guide trough 140 is located on the support plate 131, and the support plate 131 supports the guide trough 140. A connecting hole 132a is provided on the first ear plate 132, and a rotating shaft 142 is rotatably connected to the first ear plate 132. A lead screw 161 passes through the second ear plate 133. A first nut 162 is located on the left side of the second ear plate 133, and a second nut 163 is located on the right side of the second ear plate 133.

[0082] In some embodiments, the support plate 131 is horizontally positioned.

[0083] In some embodiments, the rotating shaft 142 is movably disposed within the connecting hole 132a. That is, the size of the connecting hole 132a is larger than the size of the rotating shaft 142, allowing the rotating shaft 142 to not only rotate within the connecting hole 132a but also move within it. With this design, as... Figure 8 As shown, after the guide trough 140 rotates to be flush with the upper end face of the support plate 131, the trough body 141 of the guide trough 140 can continue to rotate with the edge of the support plate 131 as a fulcrum, so that the discharge side 140b of the guide trough 140 can be lower than the feed side 140a, which helps to quickly discharge the material on the guide trough 140.

[0084] In some embodiments, the vibration reduction scale 100 further includes a counterweight mechanism 170, which includes a connecting rod 171 and a counterweight 172. The connecting rod 171 is arranged along the material conveying direction of the guide trough 140, with its two ends located on both sides of the rotating shaft 142 of the guide trough 140 and fixedly connected to the guide trough 140; the counterweight 172 is movably connected to the connecting rod 171 along the extending direction of the connecting rod 171.

[0085] That is, the length direction of the connecting rod 171 is parallel to the material conveying direction of the guide trough 140, and one end of the connecting member 1514 is located on one side of the rotating shaft 142, and the other end is located on the other side of the rotating shaft 142. Figure 5As shown, the left end of the connecting rod 171 is located to the left of the rotating shaft 142, and the right end of the connecting rod 171 is located to the right of the rotating shaft 142. Along the extension direction of the connecting rod 171, the counterweight 172 is movably connected to the connecting rod 171, allowing the counterweight 172 to be positioned at different locations on the connecting rod 171, including the left, middle, or right side regions. This design allows the position of the counterweight 172 to be adaptively adjusted according to the mass of the guide trough 140, the position of the rotating shaft 142 on the trough body 141, etc., ensuring that the guide trough 140 can smoothly occupy the first position when it is not carrying material or carries a small amount of material, thus facilitating the user's use of the vibratory reducing scale 100.

[0086] The counterweight 172 and the connecting rod 171 can be movably connected by means of snap-fit, adhesive, etc., which is not limited in this application. In some embodiments, the connecting rod 171 has an external thread, the counterweight 172 is sleeved on the connecting rod 171, and a nut is installed on each side of the counterweight 172. By tightening the two nuts to clamp the counterweight 172, the counterweight 172 can be fixed on the connecting rod 171. After loosening the nuts, the position of the counterweight 172 can be adjusted to achieve a movable connection between the counterweight 172 and the connecting rod 171.

[0087] When the material on the guide chute 140 is almost completely discharged, and there is still a small amount of material left, the guide chute 140 will rotate from the second position to the first position under the action of the support assembly 150. At this time, the material on the discharge side 140b of the guide chute 140 has not yet been completely discharged. Figure 3 As shown, to ensure complete discharge of material from the guide trough 140, in some embodiments, the guide trough 140 includes a first trough segment 143 and a second trough segment 144 connected together. The first trough segment 143 is connected to the third support 130, and the second trough segment 144 is located on the side of the first trough segment 143 away from the rotating shaft 142. The inclination angle of the second trough segment 144 is greater than that of the first trough segment 143, and when the guide trough 140 is in the first position, the second trough segment 144 is inclined downwards. With this design, when the material on the guide trough 140 is about to be discharged, during the process of the guide trough 140 rotating from the second position to the first position, the second trough segment 144 is still inclined downwards, which helps to allow the material on the second trough segment 144 to be discharged, thus helping to ensure complete discharge of material from the guide trough 140. Furthermore, with this design, when the guide trough 140 is in the first position, any remaining material on the second trough segment 144 can still be discharged along the second trough segment 144.

[0088] It should be noted that in the embodiment where the feed trough 140 includes a trough body 141, the trough body 141 includes a first trough section 143 and a second trough section 144.

[0089] The following describes the working principle of the vibration reduction scale 100, using the weighing of pellets as an example:

[0090] like Figure 6 As shown, after the vibration reduction scale 100 is installed, the positions of the counterweight 172, the first nut 162, the second nut 163, and the connecting piece 1514 are adjusted so that the guide chute 140 is in a supporting position under the support force of the support piece 152. Figure 6 The state shown is such that it can withstand a certain amount of impact without changing its elevation angle.

[0091] When the vibrating reduction scale 100 starts receiving material, the initial pellets flow along the feed chute 140 and accumulate on the feed side 140a of the feed chute 140. As the mass of the pellets gradually increases and reaches a certain threshold, the first elastic element 153 is gradually compressed under the action of the feed chute 140, and the discharge side 140b of the feed chute 140 gradually descends. After receiving material, the lower end face of the feed chute 140 presses against the upper end face of the support plate 131, and the inner wall of the rotating shaft 142 and the connecting hole 132a abuts against each other. Figure 8 As shown, the feed chute 140 is tilted downwards at this time.

[0092] When the vibratory reducing scale 100 starts unloading into the drum, the guide chute 140 is subjected to the excitation force of the vibrator 120, and the pellets are gradually unloaded from the silo 113 to the test receiving point of the rotating drum until the unloading of the vibratory reducing scale 100 reaches the set range.

[0093] After the drum test is completed, the vibrating reduction scale 100 needs to completely empty the remaining pellets in the hopper 113. The pellets in the hopper 113 are gradually discharged through vibration by the vibrator 120. When the pellets in the hopper 113 of the vibrating reduction scale 100 are reduced to a certain level, the support member 152 gradually lifts the discharge side 140b of the guide chute 140 until it reaches the desired position. Figure 6 The state shown. In this process, even if there is still a certain mass of pellets in the second trough section 144, because the inclination angle of the second trough section 144 is greater than that of the first trough section 143 and the guide trough 140 is in the first position, the second trough section 144 is inclined downwards, so the remaining pellets on the discharge side 140b of the guide trough 140 can also be discharged.
