Description

Technical Field

[0001] The utility model relates to an anti-blocking structure, in particular to an anti-blocking structure of a feed batching scale, and belongs to the technical field of batching scales. Background Art

[0002] In the prior art, for example, the utility model with application number 202320581777.6 discloses a feed batching scale anti-blocking device. In order to solve the problem of long-term vibration, knocking will cause the components on the batching device to loosen, which will have a great impact on the strength and stability of the mechanism, and even cause the mechanical parts to loosen and fall off, posing a threat to the safety of other machines and operators. In addition, during the knocking vibration, a large noise will also be generated, causing hearing damage to the operator. By setting the lever, the feed can be prevented from being blocked during the feeding process. The feed is broken up in the hopper, which avoids the accumulation of feed at the discharge port and causing blockage. Through the arrangement of the push plate and the top plate, while the feed is broken up by the lever, the feed in the hopper is squeezed inward by the push plate. At the same time, the conical top plate tops up the feed, and the feed falls onto the lever and is finally sent out through the discharge port. In this process, no loud noise and vibration are generated, which effectively prevents parts from loosening or falling, and ensures the safety of other devices and operators. At the same time, under the joint action of the top plate, the push plate and the lever, the feed can be discharged better to prevent the discharge port from being blocked.

[0003] Similar to the above application, there are still some shortcomings:

[0004] When the feed is dispersed by the movement of the top plate, the vertical movement of the top plate alone has a poor effect on the dispersion of the feed. In addition, in the process of pushing the ingredients through the thrust assembly on the side of the hopper, the reciprocating swing of the push plate easily causes the feed to flow between the push plate and the inner side of the hopper. When a lot of feed is accumulated, the push plate can no longer swing, affecting the dredging effect.

[0005] Therefore, an anti-blocking structure of a feed batching scale is designed to optimize the above problems. Utility Model Content

[0006] The main purpose of the utility model is to provide an anti-blocking structure for a feed batching scale. By installing a shaking mechanism composed of a fixed block and a corrugated groove at both ends of the hopper, the two ends of the cross bar can slide inside the corrugated groove respectively while the eccentric wheel controls the top plate on the cross bar to move up and down, thereby controlling the horizontal sliding of the top plate on the cross bar. In addition, sawtooth grooves are evenly opened on the top of the top plate, which improves the dredging effect of the ingredients during use. By symmetrically arranging conveyor belts on both sides of the hopper and using a pulley mechanism to transmit between the rollers on the conveyor belts and the output end of the motor, the ingredients can be stably conveyed downward during the discharge process, which is more practical.

[0007] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, the present embodiment provides an anti-blocking structure for a feed batching scale, comprising a hopper 1, a shaft 2 located between the two ends of a discharge port below the hopper 1, levers 3 evenly mounted on the outside of the shaft 2, and a motor 4 mounted on the outside of the hopper 1 and connected to the shaft 2 at its output end. Guide grooves 5 are vertically provided at both ends of the hopper 1, a cross bar 6 is provided between the two sets of guide grooves 5 in parallel with the direction of the shaft 2, and the cross bar 6 slides along the length direction of the guide groove 5, a top plate 7 is vertically fixed to the top of the cross bar 6, eccentric wheels 9 are fixed at both ends of the shaft 2, the surface of the eccentric wheel 9 is fitted to the bottom of the cross bar 6, and a shaking mechanism 10 for guiding the horizontal movement of the cross bar 6 is provided at both ends of the hopper 1.

[0024] The overall working principle: during the feeding process, the motor 4 drives the shaft 2 and the lever 3 to rotate, and the raw materials at the bottom of the hopper 1 are broken up. In addition, when the shaft 2 rotates, the eccentric wheel 9 is controlled to rotate. The rotation of the eccentric wheel 9 controls the top plate 7 on the cross bar 6 to rise and fall vertically inside the guide groove 5, so as to clear the feed in the middle of the hopper 1. At the same time, when the cross bar 6 rises and falls, the shaking mechanism 10 can be used to control the horizontal shaking of the top plate 7 on the cross bar 6, thereby increasing the clearing effect on the ingredients.

[0025] In this embodiment, the top end of the top plate 7 is evenly provided with sawtooth grooves 8 along the length direction, and adjacent sawtooth grooves 8 are connected end to end.

[0026] Partial working principle: The use of the sawtooth groove 8 on the top plate 7 increases the stirring effect on the ingredients during the horizontal shaking of the top plate 7, and the use effect is better.

[0027] In this embodiment, the shaking mechanism 10 includes a fixed block 11 and a corrugated groove 12 . The fixed block 11 is fixed at both ends of the hopper 1 . The inner side of the fixed block 11 is provided with a corrugated groove 12 . Both ends of the cross bar 6 extend into the interior of the corrugated groove 12 .

[0028] Partial working principle: During the vertical lifting of the cross bar 6 , the end of the cross bar 6 will slide back and forth horizontally under the guidance of the corrugated groove 12 , thereby controlling the shaking of the top plate 7 .

[0029] In this embodiment, balls 13 are rotatably mounted on the ends of the crossbar 6 , and the balls 13 fit against the inner end surface of the corrugated groove 12 .

[0030] Partial working principle: When the cross bar 6 moves inside the corrugated groove 12 , the use of the balls 13 reduces the friction between the cross bar 6 and the corrugated groove 12 .

[0031] In this embodiment, conveyor belts 14 are provided on both sides of the hopper 1 , and the two sets of conveyor belts 14 are symmetrical to each other. A pulley mechanism 16 is provided between the rollers on the conveyor belts 14 and the output end of the motor 4 .

[0032] Partial working principle: During the rotation of the motor 4, the pulley mechanism 16 drives the two sets of conveyor belts 14 to rotate, and the ingredients are conveyed downward.

[0033] In this embodiment, the outer sides of the conveyor belt 14 are uniformly provided with anti-skid grooves 15 , and the anti-skid grooves 15 are parallel to the length direction of the conveyor belt 14 .

[0034] Partial working principle: The use of the anti-skid groove 15 increases the friction between the ingredients and the conveyor belt 14, ensuring the effect of conveying the ingredients downward.

[0035] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
