Description

Technical Field

[0001] The utility model relates to supporting equipment for bulk grain storage, in particular to a non-powered rotary grain distributor. Background Art

[0002] When the building warehouse is carrying out the operation of storing bulk grain, the bulk grain is transported to the top of the corresponding warehouse room through the bulk grain conveying equipment on the warehouse roof. The top of the warehouse room is provided with a grain leakage port, and the lower side of the grain leakage port is provided with a spreading device. The bulk grain is evenly spread into the warehouse room through the grain leakage port and the spreading device.

[0003] Existing material distribution devices, such as the "rotating material distribution device" disclosed in Chinese patent CN220975853U, include a vertically arranged grain leakage drum and a grain leakage drum driving mechanism that is transmission-connected to the grain leakage drum to drive the grain leakage drum to rotate. The grain leakage drum driving mechanism includes a driving motor, and the motor output shaft of the driving motor is connected to a motor output shaft transmission wheel that is transmission-connected to the grain leakage drum. The upper end of the grain leakage drum is a grain inlet, and the lower end of the grain leakage drum is a grain outlet. At least two side wall grain outlets spaced apart along the circumferential direction are opened on the side wall of the grain leakage drum, and each side wall grain outlet is connected to a material discharge chute.

[0004] When in use, the driving motor drives the grain leaking barrel to rotate around its own rotation axis. During the rotation of the grain leaking barrel around its own rotation axis, the loose grain is rotated and distributed through each material discharge chute to ensure the uniform distribution of the loose grain in the warehouse. The existing distribution device has the following problems: the rotation of the grain leaking barrel relies on the driving motor. The setting of the driving motor will increase the structural complexity and equipment cost of the grain leaking device, and the use of the driving motor will also generate corresponding energy consumption; in addition, the rotation speed of the grain leaking barrel must match the grain feeding speed of the loose grain conveying equipment. When the grain feeding speed of the loose grain conveying equipment is fast, the rotation speed of the grain leaking barrel is required to increase; when the grain feeding speed of the loose grain conveying equipment is slow, the rotation speed of the grain leaking barrel must also slow down, and the control of the driving motor is also a problem. Utility Model Content

[0005] The utility model aims to provide a non-powered rotating grain distributor which can realize automatic rotation of a grain leaking drum to distribute grain without using a driving motor.

[0006] In order to solve the above technical problems, the technical solution of a non-powered rotating grain distributor in the utility model is as follows:

[0007] A non-powered rotary grain distributor comprises a grain distributor support, on which a grain leakage drum with a rotation axis extending in an up-down direction is rotatably mounted, the upper end of the grain leakage drum is a grain inlet for the grain leakage drum, at least two feeding chutes arranged in circumferential order are connected to the grain leakage drum, the upper end of the feeding chute is a chute inlet communicating with the grain inlet of the grain leakage drum, the lower end of each feeding chute is provided with a chute grain discharge structure, the chute grain discharge structure has at least one chute grain discharge, the chute grain discharge comprises a grain discharge bottom plate and a grain discharge reversing guide plate arranged at the lower end of the grain discharge bottom plate for blocking loose grain to change the discharge direction of the loose grain, when the loose grain flows out through each chute grain discharge, a force is applied to each grain discharge reversing guide plate so that each feeding chute generates a rotational torque in the same direction on the grain leakage drum.

[0008] Furthermore, the unloading chute is a linear chute structure.

[0009] Furthermore, the grain outlet reversing guide plate is an arc-shaped baffle.

[0010] Furthermore, the lower end of each material discharge chute is provided with two chute grain outlets, and the two chute grain outlets and the material discharge chute form a Y-shaped structure.

[0011] Furthermore, the two chute grain outlets are respectively an upper chute grain outlet and a lower chute grain outlet arranged up and down, and the grain outlet reversing guide plate of the upper chute grain outlet is located in the middle of the lower end pipe outlet of the discharge chute, thereby realizing the diversion of the grain flow in the discharge chute to the upper chute grain outlet and the lower chute grain outlet.

[0012] Furthermore, the grain outlet reversing guide plate is an arc-shaped baffle, and the radius of the grain outlet reversing guide plate at the upper side chute grain outlet is smaller than the radius of the grain outlet reversing guide plate at the lower side chute grain outlet.

[0013] Furthermore, a first guide plate outlet is provided at the bottom of one end of the grain outlet reversing guide plate of the upper chute outlet away from the discharge chute; a second guide plate outlet is provided at the bottom of one end of the grain outlet reversing guide plate of the lower chute outlet away from the discharge chute.

[0014] Furthermore, the distance between the grain outlet reversing guide plate of the upper chute outlet and the grain outlet reversing guide plate of the lower chute outlet gradually increases from the grain flow direction, and a bottom plate grain leakage port is provided at one end of the grain outlet bottom plate of the lower chute outlet away from the feeding chute.

[0015] Furthermore, the upper end openings of each material discharge chute are gathered at the bottom center of the grain leakage barrel, and the grain flow in the grain leakage barrel flows evenly into the upper end openings of each material discharge chute.

[0016] Furthermore, each material discharge chute is a semicircular groove structure, and a semicircular groove guard plate is arranged between the upper end of the material discharge chute and the grain leakage barrel.

[0017] The beneficial effects of the utility model are as follows: when the utility model is in use, the loose grain is transported to the upper side of the grain leakage drum through the loose grain conveying equipment on the top of the silo, and then diverted to each material discharge chute through the grain leakage drum, and then in the process of the downward movement of the material discharge chute, the grain is discharged through the grain discharge reversing guide plate. In the process of the loose grain being discharged through the grain discharge port of the chute, the loose grain generates a thrust on the grain discharge reversing guide plate, so that each material discharge chute generates a rotation torque in the same direction on the grain leakage drum, and the grain leakage drum realizes unpowered self-rotation under the action of the rotation torque to complete the rotary distribution. In the utility model, the rotation of the grain leakage drum does not require motor drive, so there is no need to set up a motor power mechanism, which can simplify the structure of the rotary grain distributor and reduce the manufacturing cost and use cost of the rotary grain distributor. At the same time, since the rotation power of the grain leakage drum comes from the grain flow, when the flow rate of the grain leakage drum increases, the rotation speed of the grain leakage drum will automatically increase, and when the flow rate of the grain leakage drum decreases, the rotation speed of the grain leakage drum will automatically slow down, without complex control, and the automatic adaptation of the rotation speed of the grain leakage drum and the grain distribution can be realized.

[0026] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] In the utility model, a non-powered rotary grain distributor is implemented as follows Figures 1 to 6 As shown: it includes a grain distributor support 1, on which a grain leaking barrel 2 with a rotating axis extending in the up-down direction is rotatably mounted through a bearing, the upper end of the grain leaking barrel 2 is a grain inlet of the grain leaking barrel, and the lower end of the grain leaking barrel is a grain outlet of the grain leaking barrel. The grain outlet of the grain leaking barrel is connected to two discharge chutes 4 arranged in sequence along the circumferential direction, and the angle between the two discharge chutes is 180°. In this embodiment, the discharge chute 4 is a linear chute structure whose length extends in a straight line. The upper end openings of each discharge chute gather at the bottom center of the grain leaking barrel, and the grain flow in the grain leaking barrel flows evenly to the upper end openings 10 of each discharge chute.

[0029] Each material discharge chute 4 is a semicircular groove structure with an opening facing upward, and a semicircular groove guard plate 3 is arranged between the upper end of the material discharge chute and the grain leakage barrel.

[0030] A chute grain discharge structure 5 is provided at the lower end of each material discharge chute, and the chute grain discharge structure 5 has at least one chute grain discharge port, and the chute grain discharge port includes a grain discharge port bottom plate 6 and a grain discharge reversing guide plate 7 provided at the lower end of the grain discharge port bottom plate 6 for blocking the loose grain to change the discharge direction of the loose grain. When the loose grain flows out through each chute grain discharge port, a force is applied to each grain discharge reversing guide plate so that each material discharge chute generates a same-direction rotational torque on the grain leakage barrel, and the same-direction rotational torque refers to a rotational torque in the clockwise direction or a rotational torque in the counterclockwise direction at the same time.

[0031] In this embodiment, the chute grain discharge structure has two chute discharge ports, and the two chute discharge ports and the lower chute form a Y-shaped structure. The two chute discharge ports are an upper chute discharge port 8 and a lower chute discharge port 9 respectively arranged upper and lower. The grain discharge port bottom plate of the upper chute discharge port and the grain discharge port bottom plate of the lower chute discharge port are integrally formed. The grain discharge reversing guide plate of the upper chute discharge port is located in the middle of the lower end pipe port of the lower chute, thereby realizing the diversion of the grain flow in the lower chute to the upper chute discharge port and the lower chute discharge port.

[0032] The grain outlet reversing guide plate 7 in this embodiment is an arc-shaped baffle, and the radius of the grain outlet reversing guide plate of the upper chute outlet is smaller than the radius of the grain outlet reversing guide plate of the lower chute outlet. A first guide plate grain outlet 11 is provided at the bottom of the end of the grain outlet reversing guide plate of the upper chute outlet away from the unloading chute; a second guide plate grain outlet 13 is provided at the bottom of the end of the grain outlet reversing guide plate of the lower chute outlet away from the unloading chute. The distance between the grain outlet reversing guide plate of the upper chute outlet and the grain outlet reversing guide plate of the lower chute outlet gradually increases from the grain flow direction, that is, the width of the lower chute outlet gradually increases from the grain flow direction, and a bottom plate grain leakage port 12 is provided at the end of the grain outlet bottom plate of the lower chute outlet away from the unloading chute. The grain flow in the discharge chute is diverted by the grain outlet reversing guide plate of the upper chute outlet, and flows into the upper chute outlet and the lower chute outlet respectively, and then changes the grain outlet direction under the action of the corresponding grain outlet reversing guide plates, thereby generating a rotational torque that causes the discharge chute to rotate with the grain leakage barrel. The arrangement of the first guide plate outlet, the second guide plate outlet and the bottom plate outlet helps to increase the grain outlet area, thereby further improving the uniformity of the bulk grain distribution during the rotation of the grain leakage barrel.
