Description

Technical Field

[0001] The utility model relates to the technical field of grain conveying, in particular to a turning conveyor for grain warehousing. Background Art

[0002] When grains are warehoused, multiple belt conveyors are needed. The angle of the last belt conveyor can be adjusted. The last belt conveyor mainly includes a base, a turntable, a belt conveying mechanism and a funnel. The belt conveying mechanism includes two belt conveyors arranged up and down. The lower belt conveyor can slide and extend. The belt conveying mechanism can rotate on the base through the turntable to adjust the cloth feeding angle, and the lower belt conveyor can adjust the cloth feeding position by sliding and extending.

[0003] However, when the existing turning conveyor for grain warehousing is in use, the supporting part of the belt conveying mechanism mainly relies on the base. Therefore, when the lower belt conveyor extends, in order to ensure that the base will not tip over, telescopic support legs need to be arranged around the base. By adjusting the distance between the support legs and the base and extending the support legs to support the ground, the base can be ensured not to tip over. Therefore, when in use, the following defects exist:

[0004] When the turning conveyor needs to be moved, the lower belt conveyor in the belt conveying mechanism needs to be retracted first to ensure that the belt conveying mechanism is in the shortest state before the support legs can be retracted and the base can be moved. If the lower belt conveyor is forgotten to be retracted, the base will tip over. Therefore, the operation is relatively complex during movement and there are potential safety hazards. Summary of the Utility Model

[0005] The purpose of the utility model aims to solve at least one of the technical defects described in the background art.

[0006] For this reason, an object of the utility model is to provide a turning conveyor for grain warehousing, aiming to solve the problems that the operation of the existing turning conveyor for grain warehousing is relatively complex during movement and there are potential safety hazards.

[0007] To achieve the above object, an embodiment of one aspect of the utility model provides a turning conveyor for grain warehousing, including a base. A turntable is rotatably connected to the top of the base. A first belt conveyor is hinged to the top of the turntable. A second belt conveyor is telescopically connected below the first belt conveyor. A first support rod and a second support rod are hinged to both sides of the first belt conveyor. The bottom ends of the first support rod and the second support rod are hinged to a base. The first support rod and the second support rod are equal in length and parallel to each other. A universal wheel is fixedly installed at the bottom of the base. First hydraulic cylinders are hinged to both sides of the first belt conveyor. The piston rod ends of the first hydraulic cylinders are hinged to the second support rod.

[0008] Preferably, according to any of the above solutions, the first hydraulic cylinder is located between the end of the first belt conveyor and the second support rod, and the bottoms of the first support rod and the second support rod are inclined towards the end of the first belt conveyor, changing the position of the fulcrum of the universal wheel during the lifting process, making the conveyor more stable.

[0009] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0010] 1. The first support rod and the second support rod support the middle part of the first belt conveyor through the universal wheels at the bottom, while the foundation supports the end of the first belt conveyor, thus ensuring that the foundation will not tip over. Therefore, when moving, it is not necessary to retract the second belt conveyor, and it can move stably without tipping over. Therefore, the operation during movement is simple and the safety is high.

[0011] 2. When adjusting the height of the discharge port at the end of the rotary conveyor, the universal wheel acts as a fulcrum and will move in the direction of the center of gravity. Therefore, the stability of the rotary conveyor can always be ensured, avoiding the problem of the foundation part lifting up, thus improving the practicability.

[0022] The present invention provides a steering conveyor for grain warehousing.

[0023] Embodiment 1:

[0024] As Figures 1-5As shown in the figure, it includes a base 1. A turntable 2 is rotatably connected to the top of the base 1. A first belt conveyor 3 is hinged to the top of the turntable 2. A second belt conveyor 4 is telescopically connected below the first belt conveyor 3. By rotating the turntable 2, the feeding angles of the first belt conveyor 3 and the second belt conveyor 4 can be adjusted. By rotating the first belt conveyor 3 up and down, the height of the end of the second belt conveyor 4 can be adjusted, so as to achieve the purpose of adjusting the feeding height. On both sides of the first belt conveyor 3, there are hinged a first support rod 5 and a second support rod 51. The bottom ends of the first support rod 5 and the second support rod 51 are hinged to a base 52. The first support rod 5 and the second support rod 51 are of equal length and parallel to each other, ensuring that the first support rod 5 and the second support rod 51 can rotate synchronously. A universal wheel 53 is fixedly installed at the bottom of the base 52. On both sides of the first belt conveyor 3, there are hinged first hydraulic cylinders 54. The oil tank and oil pump for controlling the telescopic movement of the first hydraulic cylinders 54 are installed above the turntable 2, so that when the first belt conveyor 3 rotates, the oil pipes will not be wound and broken. The piston rod end of the first hydraulic cylinder 54 is hinged to the second support rod 51. The first hydraulic cylinder 54 supports the second support rod 51, so as to achieve the purpose of positioning the included angles between the first support rod 5 and the second support rod 51 and the first belt conveyor 4. Therefore, by telescoping the first hydraulic cylinder 54, the first support rod 5 and the second support rod 51 can be rotated, and the universal wheel 53 rolls on the ground, so as to achieve the purpose of adjusting the height of the end of the second belt conveyor 4.

[0025] Specifically, as Figures 2-3 shown in the figure, a positioning hole 11 is opened at the top of the base 1. A positioning shaft 21 is fixedly connected to the bottom of the turntable 2. The positioning shaft 21 is rotatably connected in the positioning hole 11. A first motor 12 is fixedly installed inside the base 1. The output end of the first motor 12 is fixedly connected to a driving gear 13. The bottom end of the positioning shaft 21 is fixedly connected to a driven gear 22. The driving gear 13 meshes with the driven gear 22. The first motor 12 drives the driven gear 22 to rotate through the driving gear 13, so as to achieve the purpose of rotating the turntable 2. The rotation of the turntable 2 drives the first belt conveyor 3 and the second belt conveyor 3 to rotate, and the universal wheel 53 rotates accordingly. The universal wheel 53 moves around the base 1.

[0026] Specifically, as Figures 3-4As shown in the figure, a positioning seat 23 is fixedly connected to the center of the top of the turntable 2. Rotating shafts 24 are fixedly connected to both sides of the positioning seat 23. Supports 31 are fixedly connected to the bottoms of both side frames of the first belt conveyor 3. The supports 31 are rotatably connected to the surfaces of the rotating shafts 24. The first belt conveyor 3 can rotate around the rotating shafts 24, so as to achieve the purpose of adjusting the height of the end of the first belt conveyor 3. Hoppers 32 are fixedly connected to the tops of both side frames of the first belt conveyor 3. The hoppers 32 are located directly above the supports 31. During the rotation of the first belt conveyor 3, the positions of the hoppers 32 will not change.

[0027] Of course, it can be understood that in other embodiments, a support frame can be fixed to the side of the base 1, and the top of the support frame is fixedly connected to the hopper 32. As long as it is ensured that the hopper 32 is located above the first belt conveyor 3 and directly above the support 31. In this case, when the first belt conveyor 3 and the second belt conveyor 4 rotate around the support 31, the hopper 32 is always located directly above the feeding end of the first belt conveyor 3, ensuring that the grain sent out by the previous conveyor belt can fall onto the feeding end of the first belt conveyor 3 through the hopper 32, and then be distributed to the designated position in the grain depot through the first belt conveyor 3 and the second belt conveyor 4.

[0028] Specifically, as Figure 1 shown, rollers 14 are rotatably connected to both sides of the base 1, facilitating the movement of the conveyor. Second hydraulic cylinders 15 are fixedly installed on both sides of the base 1. The oil tank and oil pump for controlling the telescoping of the second hydraulic cylinders 15 are installed inside the base 1. The piston rod ends of the second hydraulic cylinders 15 are fixedly connected to support seats 16. Extending the second hydraulic cylinders 15 causes the support seats 16 to touch the ground, thereby being able to fix the base 1 and avoiding the problem of the conveyor moving during use.

[0029] Specifically, as Figures 4-5As shown in the figure, on both sides of the inner walls of the frames on both sides of the first belt conveyor 3, chutes 33 are provided. On both sides of the second belt conveyor 4, sliding blocks 41 are fixedly connected. The sliding blocks 41 are slidably connected in the chutes 33. By sliding in the chutes 33, the second belt conveyor 4 can be telescoped. At the bottom of the frames on both sides of the first belt conveyor 3, a plurality of suspension rods 36 are fixedly connected. Inside the suspension rods 36, a roller shaft 37 is rotatably connected. The roller shaft 37 supports the bottom of the frames on both sides of the second belt conveyor 4. At both ends of the two chutes 33, positioning blocks 34 are fixedly connected. Inside the positioning blocks 34, a screw rod 35 is rotatably connected. The screw rod 35 is threadedly connected in the sliding block 41. By rotating the screw rod 35, the sliding block 41 can be made to slide in the chute 33, thereby achieving the purpose of telescoping the second belt conveyor 4. On one side of the first belt conveyor 3, a second motor 6 is fixedly connected. On the outer surface of the output end of the second motor 6 and one end of the screw rod 35, a first sprocket 61 is fixedly connected. The two first sprockets 61 are connected by a first chain 62. On the outer surfaces of the two screw rods 35, second sprockets 63 are fixedly connected. The two second sprockets 63 are connected by a second chain 64, so that the second motor 6 can drive the two screw rods 35 to rotate synchronously.

[0030] Embodiment 2:

[0031] As Figure 1 shown, on the basis of Embodiment 1, when the first hydraulic cylinder 54 is contracted to lower the height of the end of the second belt conveyor 4, the horizontal distance between the end of the second belt conveyor 4 and the foundation 1 becomes larger. Therefore, the center of gravity moves towards the end of the second belt conveyor 4. By arranging the first hydraulic cylinder 54 between the end of the first belt conveyor 3 and the second support rod 51, the bottoms of the first support rod 5 and the second support rod 51 incline towards the end of the first belt conveyor 3. When the end of the second belt conveyor 4 is lowered, the universal wheel 53 serves as a fulcrum and moves towards the end of the second belt conveyor 4, making the moving directions of the fulcrum and the center of gravity the same. Therefore, stable support can be provided to avoid the problem of the part of the foundation 1 warping up.

[0032] The working principle of the utility model is as follows: when in use, the second hydraulic cylinder 15 is extended to make the support seat 16 contact with the ground to position the foundation 1, and then the extension and retraction of the No. 2 belt conveyor 4 is controlled by the second motor 6, so that the food falling on the No. 1 belt conveyor 3 through the funnel 32 is finally discharged from the end of the No. 2 belt conveyor 4. When it is necessary to adjust the feeding height of the end of the No. 2 belt conveyor 4, the first hydraulic cylinder 54 is extended to change the angle between the support rod 1 5 and the support rod 2 51 and the No. 1 belt conveyor 3, and the support rod 1 5 and the support rod 2 51 are gradually vertical, so as to achieve the purpose of adjusting the feeding height of the end of the No. 2 belt conveyor 4. When it is necessary to change the feeding angle, the first motor 12 is started to drive the turntable 2 to rotate, so that the No. 1 belt conveyor 3 and the No. 2 belt conveyor 4 rotate, and the universal wheel 53 rotates under the base 52, makes a circular motion around the foundation 1, and always supports the No. 1 belt conveyor 3.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. By setting support rod 1 5 and support rod 2 51, support rod 1 5 and support rod 2 51 support the middle part of No. 1 belt conveyor 3 through the universal wheel 53 at the bottom, and the foundation 1 supports the end of No. 1 belt conveyor 3, so as to ensure that the foundation 1 will not tip over. Therefore, when moving, there is no need to retract No. 2 belt conveyor 4, and it can also move stably without tipping over. Therefore, the operation is simple and safe during movement.

[0035] 2. When adjusting the height of the discharge port at the end of the steering conveyor, it is completed by extending and retracting the first hydraulic cylinder 54. In the process of adjusting the height, since the horizontal distance between the end of the No. 2 belt conveyor 4 and the foundation 1 changes, the center of gravity changes, and the universal wheel 53, as a fulcrum, will move in the direction of the center of gravity. Therefore, the stability of the steering conveyor can be always ensured, avoiding the problem of the foundation 1 being tilted, thereby improving practicality.
