In order to facilitate the feeding of the granary, mechanical equipment is usually used to realize the feeding of the granary. A belt conveyor is usually arranged on the granary, and the discharge end of the belt conveyor is arranged above the feeding port of the granary. After the grain is placed at the feeding end of the belt conveyor, the grain is conveyed to the discharge end by the belt conveyor, and then falls into the feeding port from the discharge end, completing the feeding of the granary.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] like Figs. 1-2 As shown, the utility model provides a conveying device for grain silos, which can feed multiple grain silos without having to move the device. The conveying device includes a grain conveying platform 1 located above the multiple grain silos. The upper end surface of the grain conveying platform 1 is provided with a conveyor belt 2 for conveying grain. The conveying path of the conveyor belt 2 corresponds to the multiple grain silos. By directing the grain on the conveyor belt 2 to the corresponding grain silo, the grain is fed into the corresponding grain silo, thereby enabling the conveying device to feed multiple grain silos.

[0018] In the utility model, baffles 3 higher than the conveyor belt 2 are provided on both side panels of the conveyor belt 2. The baffles 3 are used to prevent the grain on the conveyor belt 2 from falling off the conveyor belt 2. At the same time, in order to enable the grain on the conveyor belt 2 to be introduced into the corresponding granary, a plurality of grain outlets 12 corresponding to the granary are opened on the side panels of the corresponding granary. The bottom wall of the grain outlet 12 is at the same horizontal plane as the conveyor belt of the conveyor belt 2. The grain outlet 12 is provided with a guide groove plate 4 extending to the grain inlet of the granary. The grain on the conveyor belt 2 flows out from the grain outlet 12 and is transported to the corresponding granary through the guide groove plate 4, thereby completing the grain delivery.

[0019] In the utility model, a plurality of vertical rods 16 are provided on the upper end faces of the grain conveying platform 1. The upper ends of the plurality of vertical rods 16 support a top plate 7. The lower end face of the top plate 7 is provided with a vertical grain guide plate 11 corresponding one-to-one to the grain outlet 12, and a control component that drives the vertical grain guide plate 11 to rise and fall vertically. The control component controls the vertical grain guide plate 11 to descend downward, so that the vertical grain guide plate 11 can contact the conveyor belt of the conveyor belt conveyor 2, thereby intercepting the grain on the conveyor belt conveyor 2. The vertical grain guide plate 11 is an inclined plate. When the lower end face of the vertical grain guide plate 11 contacts the conveyor belt of the conveyor belt conveyor 2, one end of the vertical grain guide plate 11 is located in the grain outlet 12, and the other end contacts the baffle 3 corresponding to the grain outlet 12. The two ends of the vertical grain guide plate 11 tilt from the grain outlet 12 toward the grain feeding direction, so that the grain on the conveyor belt conveyor 2 flows into the corresponding grain outlet 12.

[0020] In the present invention, there are two structures of the control assembly to choose from. One structure is that the control assembly includes hydraulic push rods with the same number as the vertical grain guide plates 11, and the hydraulic push rods are arranged one by one between the vertical grain guide plates 11 and the top plate 7. The vertical grain guide plates 11 are connected to the top plate 7 through the hydraulic push rods. At the same time, the hydraulic push rods control the vertical lifting and lowering of the vertical grain guide plates 11 by controlling the extension and retraction of the telescopic ends, thereby achieving the diversion of the grain on the conveyor belt 2.

[0021] Another structure is based on the following structure designed control components, the upper end of the vertical guide plate 11 both ends are connected by positioning spring 6 and the top plate 7, the top plate 7 plate body located in the positioning spring 6 are provided with vertical guide rod 5, the grain baffle 13 are provided with guide hole for vertical guide rod 5 inserted. Spring 6, vertical guide rod 5 and positioning spring 6 make vertical guide plate 11 can be lifted up and down. In this case, the control assembly includes a horizontal rotation in the lower end of the top plate 7 screw 10, both ends of the screw 10 through the rotating wear in two shaft seat 9 to achieve the fixed position, screw 10 is located above all vertical guide plate 11, screw 10 on the rotating non-rotatable and small diameter end down trapezoidal block 8, all vertical guide plate 11 are located in the trapezoidal block 8 on the movement path of the inclined edge surface. By external force control screw 10 rotation, thus controlling the trapezoidal block 8 movement, when the trapezoidal block 8 moves to the corresponding vertical guide plate 11 above, can be pressed down to the vertical guide plate 11, so that the vertical guide plate 11 and the conveying belt of the conveying belt machine 2 contact, so as to realize the flow guide of the grain on the conveying belt machine 2. Here the intention of using trapezoidal block 8 is to rely on the inclination of the trapezoidal block 8 as a buffer, so as to press down the vertical guide plate 11 in the process of moving.

[0022] The difference between the two structures of the control assembly is that one electronic device controls the lifting of the vertical guide plate 11, and the other can control the lifting of the vertical guide plate 11 by pure mechanical means, and the latter is more stable.

[0023] In the utility model, in order to make the trapezoidal block 8 not rotate synchronously with the screw 10 when the screw 10 rotates, two ways are provided, one of which does not rotate, one makes the large diameter end of the trapezoidal block 8 slide with the lower end surface of the top plate 7, and the top plate 7 limits the rotation of the trapezoidal block 8. Another way is to provide a horizontal rod on the lower end surface of the top plate 7, which is parallel to the screw 10, the ends of the horizontal rod are provided with fixing blocks, the fixing blocks are connected with the lower end surface of the top plate 7, and the trapezoidal block 8 is slidably sleeved on the horizontal rod. The horizontal rod limits the rotation of the trapezoidal block 8.

[0024] In the utility model, the bottom wall of each grain outlet 12 is provided with a vertical groove 14 with a compression spring 15 inside, and the upper end of the compression spring 15 is provided with a grain baffle 13 capable of shielding the grain outlet 12. Under normal circumstances, the elastic force of the compression spring 15 stretches part of the baffle plate 13 out of the vertical groove 14, and the grain outlet 12 is shielded by the baffle plate 13, preventing the grain on the conveying belt machine 2 from flowing out of the grain outlet 12 when the corresponding grain bin is not feeding. When the grain outlet 12 needs to be discharged, the vertical guide plate 11 will enter the grain outlet 12 when it falls, thereby pressing the baffle plate 13 in the vertical groove 14 from the grain outlet 12, so that the grain can be discharged from the grain outlet 12.

[0025] The specific embodiments of the present application are described above. It should be understood that the present application is not limited to the specific embodiments described above, and various modifications or changes can be made by those skilled in the art within the scope of the claims, which do not affect the essential content of the present application.
