Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically a grain vertical elevator. Background Technology

[0002] In agricultural production and grain storage and processing, grain transportation and transfer are core links throughout the entire industry chain. Vertical lifting is a crucial process connecting different work units at different heights (such as grain silos, cleaning equipment, processing units, and transport vehicles). However, existing grain elevators still have certain shortcomings, such as: The "Grain Vertical Elevator" with application number CN202323548470.5 has a fixed discharge port position. In actual operation, when facing receiving equipment of different heights (such as grain silo entrances of different heights or cargo boxes of different models of transport vehicles) or when it is necessary to adjust the discharge direction to avoid grain accumulation, it is impossible to flexibly adjust the discharge height and angle, resulting in poor operational adaptability. It requires additional auxiliary tools or manual adjustment, which increases operating costs and labor intensity and reduces conveying efficiency. In view of this, a grain vertical elevator is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a grain vertical elevator to solve the problems mentioned in the background art, such as the fixed discharge port position of existing grain vertical elevators and the inconvenience of adjusting the height and angle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grain vertical lifting machine, including a base; A feeding cylinder is fixedly installed on the right end of the top surface of the base, and a hopper is fixedly installed on the left end of the top surface of the base. The lower end of the left side wall of the feeding cylinder is connected to the lower end of the right side wall of the hopper through a feeding pipe. A rotating rod is installed at the center of the inner bottom surface of the feeding cylinder through a bearing, and the rotating rod passes through the center of the top of the feeding cylinder through a bearing. A spiral blade is fixedly installed on the surface of the rotating rod, and the spiral blade is located inside the feeding cylinder. A discharge pipe is fixedly provided through the upper end of the right side wall of the feeding cylinder, and a feeding mechanism is movably provided at the bottom end of the discharge pipe.

[0005] The above technical solution facilitates the formation of a complete vertical grain conveying channel. Grains are fed centrally through a hopper, and then introduced into the conveying cylinder through a feed pipe. The rotating rod drives the spiral blades to rotate, conveying the grains from the bottom of the conveying cylinder upwards to the discharge pipe, and finally discharged flexibly through the feeding mechanism.

[0006] As a preferred embodiment of this utility model, a frame is fixedly installed on the top surface of the feeding cylinder, and a first motor is fixedly installed on the inner bottom surface of the frame. The shaft end of the first motor is coaxially and fixedly connected to the top end of the rotating rod.

[0007] By adopting the above technical solution, it is easy to provide stable installation support for the first motor through the frame, ensuring the stability of the motor during operation, while the first motor can directly provide driving force to the rotating rod.

[0008] As a preferred embodiment of this utility model, the feeding mechanism includes a telescopic tube, which is fixedly installed at the bottom end of the discharge pipe, and a connecting pipe is fixedly installed at the bottom end of the discharge pipe, and the feeding pipe is installed at the bottom end of the connecting pipe through a bearing.

[0009] The above technical solution facilitates the use of the telescopic tube's expandability to adjust the material discharge height, adapting to receiving equipment of different heights. Furthermore, the bearing-connected structure allows the material discharge tube to rotate around its own axis, enabling flexible adjustment of the discharge direction and achieving multi-angle discharge. This effectively expands the equipment's applicability and meets diverse unloading needs.

[0010] As a preferred embodiment of this utility model, an installation plate is fixedly installed on the right side of the conveying cylinder, and an electric telescopic rod is fixedly installed on the bottom surface of the installation plate. A lifting plate is fixedly installed at the output end of the electric telescopic rod, and a connecting pipe is fixedly installed through the lifting plate longitudinally.

[0011] The above technical solution facilitates the reliable installation support of the electric telescopic rod through the mounting plate. The electric telescopic rod can drive the lifting plate to rise and fall stably, and then drive the connecting pipe and the discharge pipe to rise and fall synchronously through the lifting plate, so as to realize the adjustment of the discharge height.

[0012] As a preferred technical solution of this utility model, the bottom surface of the lifting plate is equipped with a rotating shaft through a bearing, and a drive gear is fixedly installed on the surface of the rotating shaft. The drive gear meshes with a driven gear fixedly installed on the surface of the feed pipe.

[0013] By adopting the above technical solution, it is easy to drive the drive gear to rotate through the rotating shaft, and the drive gear drives the driven gear to rotate, thereby driving the feed pipe to rotate, realizing the controllable adjustment of the discharge angle and avoiding the accumulation of grains during discharge.

[0014] As a preferred technical solution of this utility model, a housing is fixedly installed on the bottom surface of the lifting plate, and the feeding pipe passes through the bottom of the housing through a bearing. The driving gear and the driven gear are located inside the housing. A second motor is fixedly installed on the inner bottom surface of the housing, and the shaft end of the second motor is coaxially and fixedly connected to the bottom end of the rotating shaft.

[0015] By adopting the above technical solution, it is easy to provide a stable driving force to the shaft through the second motor, ensuring the continuous operation of the gear transmission mechanism. At the same time, the chassis can isolate the drive gear, driven gear and other transmission components from the external environment, effectively preventing grain dust from entering the transmission mechanism and causing wear, thus extending the service life of the equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the grain vertical elevator can flexibly adjust the discharge height and angle to adapt to different operating scenarios, improve the convenience and adaptability of grain conveying and transfer, and is easy and flexible to operate with strong practicality. 1. The lifting plate is driven to move up and down by an electric telescopic rod. With the extension and retraction characteristics of the telescopic tube, the height of the discharge pipe can be stably adjusted. It is suitable for receiving equipment such as grain silo entrances and cargo boxes of transport vehicles of different heights. No additional auxiliary tools or manual adjustment are required, which significantly reduces operating costs and labor intensity. 2. The second motor drives the rotating shaft to rotate the drive gear. Through the meshing transmission between the drive gear and the driven gear on the surface of the feed pipe, the feed pipe can be rotated flexibly around its own axis, realizing the controllable adjustment of the discharge angle. This effectively avoids the accumulation of grains during discharge and further improves the conveying efficiency. Attached Figure Description

The inner bottom surface of the hopper 3 is inclined from left to right. The lower end of the left side wall of the conveying cylinder 2 is connected to the lower end of the right side wall of the hopper 3 through a feed pipe 4. A rotating rod 5 is installed at the center of the inner bottom surface of the conveying cylinder 2 through a bearing, and the rotating rod 5 passes through the top center of the conveying cylinder 2 through a bearing. A spiral blade 6 is fixedly installed on the surface of the rotating rod 5, and the spiral blade 6 is located inside the conveying cylinder 2. A discharge pipe 7 is fixedly provided through the upper end of the right side wall of the conveying cylinder 2, and a feeding mechanism is movably provided at the bottom end of the discharge pipe 7.

[0021] A frame 8 is fixedly installed on the top surface of the feeding cylinder 2, and a first motor 9 is fixedly installed on the inner bottom surface of the frame 8. The shaft end of the first motor 9 is coaxially and fixedly connected to the top end of the rotating rod 5.

[0022] The feeding mechanism includes a telescopic tube 10, which is fixedly installed at the bottom end of the discharge tube 7. A connecting tube 11 is fixedly installed at the bottom end of the discharge tube 7, and a feeding tube 12 is installed at the bottom end of the connecting tube 11 via a bearing.

[0023] An installation plate 13 is fixedly installed on the right side of the material conveying cylinder 2, and an electric telescopic rod 14 is fixedly installed on the bottom surface of the installation plate 13. A lifting plate 15 is fixedly installed at the output end of the electric telescopic rod 14, and a connecting pipe 11 is fixedly installed through the lifting plate 15 longitudinally.

[0024] A rotating shaft 16 is mounted on the bottom surface of the lifting plate 15 via a bearing, and a drive gear 17 is fixedly mounted on the surface of the rotating shaft 16. The drive gear 17 meshes with a driven gear 18 fixedly mounted on the surface of the feed tube 12.

[0025] A housing 19 is fixedly installed on the bottom surface of the lifting plate 15, and the feeding pipe 12 passes through the bottom of the housing 19 through a bearing. The driving gear 17 and the driven gear 18 are located inside the housing 19. A second motor 20 is fixedly installed on the inner bottom surface of the housing 19, and the shaft end of the second motor 20 is coaxially and fixedly connected to the bottom end of the rotating shaft 16.

[0026] Working principle: When in use, the grain to be conveyed is poured into the hopper 3 at the left end of the top surface of the base 1. The grain flows along the inclined inner bottom surface of the hopper 3 and enters the bottom of the conveying cylinder 2 at the right end of the top surface of the base 1 through the feed pipe 4. The first motor 9 in the frame 8 on the top surface of the conveying cylinder 2 is started. The shaft end of the first motor 9 drives the rotating rod 5 inside the conveying cylinder 2 to rotate. The spiral blades 6 on the surface of the rotating rod 5 rotate synchronously. Through the rotational force of the spiral blades 6, the grain at the bottom of the conveying cylinder 2 is vertically conveyed upward to the discharge pipe 7 at the upper end of the right side wall of the conveying cylinder 2. The grain enters the telescopic pipe 10 at the bottom through the discharge pipe 7, and then flows into the connecting pipe 11 through the telescopic pipe 10. Finally, it is discharged from the discharge pipe 12 at the bottom of the connecting pipe 11. When the discharge height needs to be adjusted, the electric telescopic rod 14 on the bottom of the mounting plate 13 on the right side of the conveying cylinder 2 is activated. The output end of the electric telescopic rod 14 drives the lifting plate 15 to rise and fall. The lifting plate 15 drives the connecting pipe 11 and the discharge pipe 12 that pass through it to rise and fall synchronously. At the same time, the telescopic pipe 10 extends and retracts to cooperate with the height adjustment. When the discharge angle needs to be adjusted, the second motor 20 inside the housing 19 on the bottom surface of the lifting plate 15 is started. The shaft end of the second motor 20 drives the rotating shaft 16 to rotate, and the drive gear 17 on the surface of the rotating shaft 16 rotates accordingly. The drive gear 17 meshes with the driven gear 18 on the surface of the feeding pipe 12, thereby driving the feeding pipe 12 to rotate around its own axis, realizing flexible adjustment of the discharge angle. Finally, the grain is accurately conveyed to the target receiving equipment through the feeding pipe 12 after the height and angle are adjusted.
