Description

Technical Field

[0001] This utility model relates to a grain distribution device for bulk grain storage, and more particularly to a non-powered rotary grain distributor. Background Technology

[0002] When bulk grain is stored in a warehouse, a rotary grain distributor is required. This distributor includes a vertically positioned grain distribution cylinder with at least two circumferentially spaced grain distribution chutes connected to it. Its working principle is as follows: a grain distribution hole is provided in the warehouse roof, and the grain distribution cylinder is positioned at this hole. The bulk grain is transported to the upper part of the grain distribution cylinder by a grain conveying device on the upper side of the warehouse roof. The bulk grain enters through the grain inlet at the top of the distribution cylinder and is then evenly distributed into the respective grain distribution chutes. The grain distribution chutes and the distribution cylinder rotate around their own axes of rotation, and the bulk grain, under gravity, slides down into the warehouse through its corresponding chutes, thus completing the bulk grain storage operation.

[0003] There are two types of traditional rotary grain distributors: powered and unpowered. Powered rotary grain distributors require a drive motor to rotate the grain distribution cylinder. Because of the need for a drive motor and the transmission between the drive motor and the grain distribution cylinder, the structure of this type of rotary grain distributor is more complex and the cost of the device is higher.

[0004] The applicant prefers to use a non-powered rotary grain distributor, which refers to a grain chute with an arc-shaped structure. As the bulk grain slides down the chute, the force of the grain causes the chute to rotate, thus achieving uniform distribution of the bulk grain during rotation. When the grain flow rate decreases, the force of the bulk grain on the chute also decreases, and the circumferential rotation speed of the grain distribution cylinder decreases. Therefore, this non-powered rotary grain distributor can achieve automatic rotation of the grain distribution cylinder according to the grain flow rate. Because it does not require a motor and a transmission structure between the motor and the grain distribution cylinder, its structure is simpler and its cost is lower.

[0005] However, the existing technology of this non-powered rotary grain distributor has the following problems: when bulk grain is put into the silo, a lot of dust is generated. The sealing structure between the grain distribution cylinder and the grain distribution hole in the existing technology is not ideal, which causes the dust to flow to the outside of the silo top through the gap between the grain distribution cylinder and the grain distribution hole. In addition, in the existing technology, the bulk grain can only be discharged through the chute outlet at the bottom of the grain distribution chute, which results in a limited minimum grain distribution radius. It is not easy to distribute grain in the area directly below the grain distribution chute. Utility Model Content

[0006] The purpose of this invention is to provide a non-powered rotating grain distributor that can effectively seal the gap between the grain distribution cylinder and the grain distribution hole.

[0007] To solve the above-mentioned technical problems, the technical solution of the non-powered rotary grain distributor in this utility model is as follows:

[0008] A non-powered rotary grain distributor includes a grain dispensing cylinder and at least two grain dispensing chutes arranged sequentially along the circumference. The upper end of the grain dispensing chutes is a grain inlet connected to the top of the chutes and the lower end is a grain outlet. The non-powered rotary grain distributor also includes a dust cover. The bottom outer periphery of the dust cover has a dust cover connecting edge for connecting with the upper end of the grain dispensing hole. A rotating bearing is provided on the inner side of the dust cover. The outer ring of the rotating bearing is connected to the dust cover, and the inner ring of the rotating bearing is connected to the grain dispensing cylinder. A bulk grain transition cylinder with a bottom for feeding bulk grain into the grain dispensing cylinder is fixed to the top of the dust cover. A grain dispensing funnel is connected to the upper end of the bulk grain transition cylinder by a clamp.

[0009] Furthermore, the distance between the grain distribution funnel and the grain transfer cylinder is adjustable.

[0010] Furthermore, the dust cover connecting edge is connected to the upper end of the grain distribution hole edge by bolts.

[0011] Furthermore, an annular connecting plate is provided between the dust cover connecting edge and the upper end of the grain distribution hole edge, and the outer ring of the rotating bearing is fixed to the upper side of the annular connecting plate.

[0012] Furthermore, the grain distribution cylinder is fixed to the bottom of the inner ring of the bearing, and the lower end of the bulk grain transition cylinder extends to the inner side of the inner ring of the bearing. The outer diameter of the lower end of the bulk grain transition cylinder is smaller than the inner diameter of the upper end of the grain distribution cylinder.

[0013] Furthermore, the bottom height of the bulk grain transfer cylinder should not be higher than the top height of the grain distribution cylinder.

[0014] Furthermore, at least two grain leakage ports are provided at intervals along the length of the grain distribution chute between the grain inlet at the top of the chute and the grain outlet at the bottom of the chute.

[0015] Furthermore, the bottom of the grain distribution chute is also equipped with a grain leakage port sealing plate corresponding to the grain leakage port of the chute. The grain leakage port sealing plate is driven by the sealing plate driving mechanism and can move along the length of the grain distribution chute to close or open the corresponding grain leakage port of the chute.

[0016] Furthermore, the chute has two grain leakage outlets and two grain leakage outlet sealing plates. The sealing plate driving mechanism includes a sealing plate driving motor. A sealing plate driving screw is connected to the power output end of the sealing plate driving motor. The sealing plate driving screw is threadedly connected to the two grain leakage outlet sealing plates to drive the two grain leakage outlet sealing plates to move in the same direction. When the two grain leakage outlet sealing plates move in the same direction, the two grain leakage outlets can be opened simultaneously or any one of the grain leakage outlets can be opened individually.

[0017] The beneficial effects of this utility model are as follows: In use, bulk grain falls through the grain distribution funnel into the bulk grain transition cylinder, then through the transition cylinder into the grain distribution cylinder, and finally enters the grain distribution chute through the grain inlet at the top of each distribution chute, thus achieving grain distribution. The grain distribution cylinder is connected to the inner ring of the rotating bearing. The dust cover not only enables the installation of the grain distribution cylinder via the rotating bearing, but also enables the installation of the bulk grain transition cylinder, and provides dust prevention between the grain distribution cylinder and the distribution holes.

[0026] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0028] Example 1 of the non-powered rotary grain distributor of this utility model is as follows: Figures 1-4 As shown:

[0029] It includes a grain distribution cylinder 8 and two grain distribution chutes 10 arranged sequentially along the circumference of the grain distribution cylinder. The grain distribution cylinder 8 is vertically arranged in the middle of the grain distribution hole 7 on the top of the silo 13. The upper end of the grain distribution chutes 10 is the grain inlet at the top of the chutes connected to the grain distribution cylinder 8. The lower end of the grain distribution chutes is provided with an arc-shaped baffle plate 11, and the arc-shaped baffle plate 11 forms the grain outlet 12 at the bottom of the chutes. The side wall of the grain distribution chutes is provided with a side wall grain outlet 9.

[0030] The non-powered rotary grain distributor also includes a dust cover 6. The bottom outer periphery of the dust cover 6 has a dust cover connecting edge 5 for connecting with the upper end of the grain distribution hole. The dust cover connecting edge 5 is connected to the upper end of the grain distribution hole by bolts. A rotating bearing 4 is provided inside the dust cover. The outer ring 14 of the rotating bearing 4 is connected to the dust cover, and the inner ring 15 of the rotating bearing is fixedly connected to the grain distribution cylinder 8. A bulk grain transition cylinder 3 with its bottom for feeding bulk grain into the grain distribution cylinder is fixed to the top of the dust cover. The upper end of the bulk grain transition cylinder 3 is connected to the grain distribution funnel 1 by a clamp 2.

[0031] An annular connecting plate 16 is provided between the dust cover connecting edge 5 and the upper end hole edge of the grain distribution hole. The annular connecting plate 16 is fixed between the dust cover connecting edge 5 and the upper end hole edge of the grain distribution hole. The outer ring 14 of the rotating bearing 4 is fixed to the upper side of the annular connecting plate 16.

[0032] Since the grain distribution funnel and the bulk grain transition cylinder are connected by a clamp, during the specific installation, the height of the grain distribution funnel 1 can be adjusted according to the grain discharge height of the grain conveying equipment on the top of the silo, that is, the distance between the grain distribution funnel 1 and the bulk grain transition cylinder 3 can be adjusted. Then, the clamp is used to connect the grain distribution funnel and the bulk grain transition cylinder, so as to realize that the distance between the grain distribution funnel and the bulk grain transition cylinder is adjustable.

[0033] In this embodiment, the bulk grain transfer cylinder includes an upper cylinder portion 17 fixed to the upper side of the dust cover top plate and a lower cylinder portion 18 fixed to the lower side of the dust cover top plate. The grain distribution funnel is fixed to the upper end of the upper cylinder portion 17 by a clamp 2. The lower end of the lower cylinder portion 18 extends to the inner side of the bearing inner ring 15, and the outer diameter of the lower end of the lower cylinder portion is smaller than the inner diameter of the upper end of the grain distribution cylinder 8. The bottom height of the lower cylinder portion 18 is not higher than the top height of the grain distribution cylinder.

[0034] In use, the dust cover is fixed to the grain distribution hole with bolts. Then, the height of the grain distribution funnel is adjusted according to the discharge position of the grain conveying equipment on the top of the silo. Finally, the grain distribution funnel is fixed to the upper cylinder with clamps. Bulk grain flows into the grain distribution funnel through the grain conveying equipment, then flows through the bulk grain transition cylinder to the grain distribution cylinder, and finally flows into the grain silo through each grain distribution chute.

[0035] Example 2 of a non-powered rotating grain distributor Figures 5-6 As shown:

[0036] The difference between Example 2 and Example 1 is that, in order to distribute grain to the lower side of the grain distribution chute 10, two grain leakage ports 19 are provided at intervals along the length of the grain distribution chute between the grain inlet at the top of the chute and the grain outlet at the bottom of the chute.

[0037] The bottom of the grain distribution chute is also provided with two grain outlet sealing plates 20, which are respectively set with the grain outlet of their respective chute. The grain outlet sealing plates 20 are driven by the sealing plate driving mechanism and can move along the length of the grain distribution chute to close or open the corresponding grain outlet 19.

[0038] In this embodiment, a mounting base 23 is provided at the bottom of the grain chute 10. A sealing plate drive screw 21 is rotatably mounted on the mounting base 23. Two guide rods 22 are also fixed on the mounting base. The sealing plate drive mechanism includes a sealing plate drive motor 24. The power output end of the sealing plate drive motor 24 is connected to the sealing plate drive screw. Specifically, a motor shaft gear 25 is fixed on the motor shaft of the sealing plate drive motor, and a screw gear 26 that meshes with the motor shaft gear is fixed on the sealing plate drive screw. Each grain leakage port sealing plate includes a sealing plate 20-1 and a vertical plate 20-2 connected to the sealing plate 20-1. The sealing plate 20-1 and the vertical plate 20-2 form an L-shaped structure. The guide rods 22 are guided and moved with the vertical plate 20-2, and the sealing plate drive screw 21 is threadedly engaged with the vertical plate 20-2.

[0039] like Figure 5As shown, both chute outlets are open at this time. As the bulk grain flows through the grain distribution chute, it can leak through these outlets to distribute the grain downwards. When the sealing plate drive screw rotates forward, the two sealing plates move in the same direction towards the grain inlet at the top of the chute. One sealing plate is closer to the corresponding chute outlet, while the other is farther away. One sealing plate will initially block the corresponding chute outlet. If the sealing plate drive screw stops rotating at this point, only one sealing plate outlet will be open. If the sealing plate drive screw continues to rotate forward, the sealing plate blocking the corresponding chute outlet will open, and the initially farther sealing plate will block the corresponding chute outlet. This allows a single sealing plate drive mechanism to selectively block the corresponding chute outlet, enabling grain distribution at different radial positions.
