Abstract
Description
Technical Field
[0001] This utility model relates to equipment for bulk grain storage, and more particularly to a bulk grain storage device for flat warehouses. Background Technology
[0002] When bulk grain is stored, it is generally transported to the outside of the warehouse by grain trucks, and then transported into the warehouse by a bulk grain entry device, which usually consists of multiple bulk grain conveyor trucks.
[0003] Existing bulk grain output vehicles include the “A type of bulk grain distribution vehicle for flat warehouses and its frame” disclosed in Chinese patent CN216917287U. This patent document discloses a type of bulk grain distribution vehicle for flat warehouses, which is actually a device for bulk grain entry into flat warehouses. It includes a grain distribution vehicle frame, and a walking mechanism is provided at the bottom of the grain distribution vehicle frame. The walking mechanism includes walking wheels and a walking wheel drive mechanism for driving the walking wheels.
[0004] The grain distribution vehicle is equipped with a grain conveying mechanism on its frame for transporting bulk grain from bottom to top and from back to front. This mechanism is a belt conveyor with a conveyor belt. In operation, the bulk grain falls onto the conveyor belt at the rear bottom of the grain conveyor and is then transported from bottom to top and from back to front. Finally, the grain is scattered into the flat warehouse through the discharge end of the belt conveyor, thus forming a grain pile at one dropping point. Once the dropping point is full, the angle of the distribution vehicle frame needs to be rotated by the traveling mechanism to change the circumferential position of the discharge end of the belt conveyor, in order to distribute grain at the next dropping point.
[0005] The existing bulk grain warehousing device has the following problems: when it is necessary to change the circumferential position of the discharge end of the belt conveyor, the entire grain distribution car frame and belt conveyor mechanism can only be rotated circumferentially by the traveling mechanism. The grain distribution car frame and belt conveyor mechanism are large in size and heavy, making it difficult to rotate them circumferentially. In addition, after a grain pile is formed, the top of the grain pile needs to be flattened, but the existing bulk grain warehousing device does not have the function of being flattened by the top of the pile. Utility Model Content
[0006] The purpose of this utility model is to provide a flat warehouse bulk grain loading device to solve the technical problem that the existing technology requires the overall movement of the grain loading vehicle frame and belt conveyor mechanism to change the circumferential grain loading position of the flat warehouse bulk grain loading device, which is inconvenient during the movement process.
[0007] The technical solution of this utility model for the bulk grain storage device in a flat warehouse is as follows: A bulk grain loading device for a flat warehouse includes a frame, on which a main belt conveyor mechanism for conveying bulk grain from back to front and from bottom to top is mounted. A front support is mounted at the front end of the frame. The bulk grain loading device also includes a front belt conveyor mechanism located below the front end of the main belt conveyor mechanism. The front belt conveyor mechanism is mounted on the front belt conveyor mechanism support, which is rotatably mounted on the front support. A grain hopper is also mounted on the front belt conveyor mechanism support between the front end of the main belt conveyor mechanism and the front belt conveyor mechanism. The grain hopper and the rotation axis of the front belt conveyor mechanism support are coaxial. A swing drive mechanism is mounted on the front support to drive the front belt conveyor mechanism support to swing back and forth.
[0008] Furthermore, the upper end of the grain hopper is a hopper inlet for receiving the material discharged from the main belt conveyor mechanism, and the lower end of the grain hopper is a hopper outlet corresponding to the front belt conveyor mechanism. The size of the hopper inlet is larger than the size of the hopper outlet.
[0009] Furthermore, the front-end support is hinged to the front end of the device frame, and a support drive cylinder is provided between the device frame and the front-end support to drive the pitch angle adjustment of the front-end support.
[0010] Furthermore, the front-end support includes a support base and a left support connecting rod and a right support connecting rod fixed to the rear end of the support base. The left support connecting rod and the right support connecting rod are vertically arranged, and the upper ends of the left support connecting rod and the right support connecting rod are hinged to the left and right sides of the device frame.
[0011] Furthermore, there are two support drive cylinders, which are respectively arranged on the left and right sides of the device frame. The piston rod of the support drive cylinder is hinged to the rear end of the support base.
[0012] Furthermore, a rotating shaft is fixed at the bottom of the front belt conveyor support bracket. The rotating shaft is rotatably mounted on the support base. The swing drive mechanism is set on the support base and is connected to the rotating shaft for transmission.
[0013] Furthermore, the swing drive mechanism includes a vertically arranged drive motor, a first connecting rod fixed on the motor shaft of the drive motor, a second connecting rod fixed on the rotating shaft, and the first and second connecting rods connected by a third connecting rod. One end of the third connecting rod is hinged to the first connecting rod, and the other end of the third connecting rod is hinged to the second connecting rod.
[0014] The beneficial effects of this technical solution are as follows: In use, the bulk grain is first transported from back to front and from bottom to top to the grain outlet end of the main belt conveyor mechanism. Then, the bulk grain falls onto the front belt conveyor mechanism via the grain drop hopper. The front belt conveyor mechanism transports the bulk grain from back to front into the flat warehouse. The front belt conveyor mechanism is installed on the front support. The swing drive mechanism can drive the front support to swing back and forth. The front support carries the front belt conveyor mechanism to swing back and forth, thereby changing the circumferential position of the bulk grain inlet device in the flat warehouse. In this utility model, it is not necessary to move the heavy and bulky device frame and the main belt conveyor mechanism. The circumferential position of the grain distribution can be changed simply by rotating the smaller front belt conveyor mechanism, making the overall implementation simpler and more convenient.

The frame 2 is equipped with a main belt conveyor 1 for conveying the corresponding bulk grain from back to front and from bottom to top. The main belt conveyor 1 includes conveyor rollers 13 spaced apart at the front and back and a conveyor belt wound around the conveyor rollers. The conveyor rollers are rotatably mounted on the side plates 12 of the frame. The side plates 12 of the frame are located on both sides of the conveyor rollers 13. All of the above are existing technologies and will not be described in detail here.
[0021] A front support 5 is installed at the front end of the device frame 2. The front support 5 is hinged to the front end of the device frame 2. A support drive cylinder 4 for driving the pitch angle adjustment of the front support is provided between the device frame 2 and the front support 5.
[0022] In this embodiment, the front-end bracket 5 includes a bracket base 8 and a left bracket connecting rod and a right bracket connecting rod fixed to the rear end of the bracket base 8. The left and right bracket connecting rods are vertically arranged. The upper end of the left bracket connecting rod is hinged to the left side plate of the device frame, and the upper end of the right bracket connecting rod is hinged to the right side plate of the device frame. There are two bracket drive cylinders 4. The cylinder body of the left bracket drive cylinder is hinged to the left side plate of the device frame, and the cylinder body of the right bracket drive cylinder is hinged to the right side plate of the device frame. The piston rod of the bracket drive cylinder 4 is connected to the rear end of the bracket base 8.
[0023] By extending and retracting the piston rod of the support drive cylinder 4, the pitch angle of the support base 8 can be adjusted. On the one hand, the final discharge height can be adjusted. On the other hand, when the support base is adjusted to a horizontal position, the support base 8 can also be used to flatten the top of the grain pile.
[0024] The bulk grain loading device for the flat warehouse also includes a front belt conveyor mechanism 10 located below the front end of the main belt conveyor mechanism 1. The front belt conveyor mechanism 10 is mounted on a front belt conveyor mechanism support 9, which is rotatably mounted on a front support 5. A grain hopper 11 is also mounted on the front belt conveyor mechanism support 9, located between the front end of the main belt conveyor mechanism and the front belt conveyor mechanism. The grain hopper 11 is coaxial with the rotation axis of the front belt conveyor mechanism support 9. A swing drive mechanism 6 is mounted on the front support 5 to drive the front belt conveyor mechanism support 9 to reciprocate. The width and length of the front belt conveyor mechanism 9 are smaller than those of the main belt conveyor mechanism, and the weight of the front belt conveyor mechanism is no more than 1 / 8 of the weight of the main belt conveyor mechanism.
[0025] In this embodiment, hopper side plates 14 are fixed on the left and right sides of the grain hopper, and the bottom of the hopper side plates 14 is fixed on the front belt conveyor bracket 9.
[0026] The upper end of the grain hopper 11 is a hopper inlet 19 for receiving the discharge from the main belt conveyor mechanism, and the lower end of the grain hopper 11 is a hopper outlet 20 corresponding to the front belt conveyor mechanism. The size of the hopper inlet 19 is larger than the size of the hopper outlet, and the hopper outlet 20 is located on the upper side of the conveyor belt of the front belt conveyor mechanism.
[0027] The connection between the front belt conveyor mechanism bracket 9 and the front bracket 5 is achieved by the following means: a rotating shaft 7 is fixed at the bottom of the front belt conveyor mechanism bracket, and the rotating shaft 7 is rotatably mounted on the bracket base 8 through bearings. The swing drive mechanism 6 is set on the bracket base 8, and the swing drive mechanism is connected to the rotating shaft to drive the rotating shaft to reciprocate.
[0028] In this embodiment, the swing drive mechanism includes a vertically arranged drive motor 15. A first connecting rod 16 is fixed on the motor shaft of the drive motor 15, and a second connecting rod 17 is fixed on the rotating shaft 7. The first connecting rod 16 and the second connecting rod 17 are connected by a third connecting rod 18. One end of the third connecting rod 18 is hinged to the first connecting rod 16, and the other end of the third connecting rod 18 is hinged to the second connecting rod 17. In use, the drive motor drives the first connecting rod to rotate unidirectionally around the axis of the motor shaft. The first connecting rod, through the third connecting rod, drives the second connecting rod to swing back and forth. The second connecting rod, through the rotating shaft, drives the front belt conveyor mechanism bracket to swing back and forth, thereby adjusting the circumferential position of the grain outlet of the front belt conveyor mechanism.
[0029] An arc-shaped guide rail 21 is provided at the front end of the support base. The arc-shaped guide rail is coaxial with the rotating shaft. A slider 22 is provided at the bottom of the front belt conveyor support, which moves in coordination with the arc-shaped guide rail. When the front belt conveyor support swings back and forth, the slider 22 moves in coordination with the arc-shaped guide rail 21. The slider plays a supporting role for the front belt conveyor support.
[0030] In operation, bulk grain is conveyed from back to front and from bottom to top via the main belt conveyor. After being ejected from the discharge end of the main belt conveyor, the grain enters through the hopper inlet and is then discharged through the hopper outlet onto the conveyor belt of the front belt conveyor, where it is conveyed from back to front until it is placed into the flat storage silo. During operation, the front belt conveyor can continuously reciprocate to change the circumferential grain distribution position, or it can change the circumferential grain distribution position after distributing grain at one location. When distributing grain at one location is complete, the front belt conveyor support can be leveled, and then the reciprocating swing of the support can be used to flatten the top of the grain pile.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
