[0003] The existing patent (publication number: CN217200314U) discloses a grain screw conveying device, including a fixed seat, the top of the fixed seat is provided with a rectangular groove, the inside of the rectangular groove is slidably connected to the bottom plate, the fixed seat and the bottom plate are connected by a shock-absorbing spring, the top side of the bottom plate is fixedly connected to a vertical plate, the outer side of the vertical plate is fixedly connected to two first fixed plates, the first fixed plate and the barrel are connected by a first bearing, one side of the top of the barrel is fixedly connected to a material receiving box, the material receiving box is perpendicular to the barrel, one end of the barrel is provided with a motor, the output end of the motor and a spiral rod located inside the barrel; this device moves the device to a suitable position through a universal wheel at the bottom of the fixed seat, installs the bottom plate through the rectangular groove, and cooperates with the shock-absorbing spring to improve the shock-absorbing performance of the device. At the same time, the conveying position of the device can be adjusted, which is convenient for users to convey materials to different heights and improves the practicality of the device.

[0004] The above-mentioned conveying device installs the bottom plate through a rectangular groove. The bottom plate cooperates with the shock-absorbing spring to improve the shock-absorbing performance of the device. However, the spring will quickly reset after being under pressure, and there is a lack of damping mechanism, which causes the screw rod to shake more. Secondly, during the discharging process of common conveyors, the discharge port is far away from the receiving container, and the dust in the grain is easily diffused, affecting the health of workers.

The addition of the damper effectively reduces the impact when the spring is reset, so that the device can run more smoothly when subjected to external force, thereby improving the transportation stability and material transportation quality. A bellows is added at the bottom of the discharge pipe. This design makes it easy for users to adjust the length of the bellows according to different receiving containers, reducing the dust diffusion problem caused by the large drop in grain during transportation.

[0013] Furthermore, a conveying shaft is rotatably connected between the left and right inner walls of the conveying cylinder, and an auger blade is fixedly connected to the outer surface of the conveying shaft.

[0014] Through the above scheme, the purpose of pushing grains can be achieved by setting the auger blades.

[0015] Furthermore, a motor is installed at the right end of the conveying cylinder, and the output end of the motor is fixedly connected to the conveying shaft.

[0019] Furthermore, a height sensor is installed at the left end of the conveying cylinder.

[0020] Through the above solution, by setting the height sensor, it is convenient for the user to control the height of the discharge pipe.

[0021] Furthermore, a control host is installed on the upper surface of the shock-absorbing plate, and the motor, hydraulic rod and height sensor are all electrically connected to the control host.

[0022] Through the above solution, the purpose of controlling the electrical components can be achieved by controlling the settings of the host.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] This spiral conveying device significantly improves the shock absorption effect through the combined design of shock-absorbing plates, buffer rods, springs and dampers.

A hydraulic rod 11 is hinged between the middle end of the conveying cylinder 6 and the left end of the shock-absorbing plate 2. The right end of the conveying cylinder 6 is hinged to the shock-absorbing plate 2. Through the setting of the hydraulic rod 11, the height of the left end of the conveying cylinder 6 can be adjusted. The right end of the conveying cylinder 6 is fixedly connected to the feed pipe 7, and the left end of the conveying cylinder 6 is fixedly connected to the discharge pipe 8. The bottom end of the discharge pipe 8 is fixedly connected to the bellows 9. Through the setting of the bellows 9, the distance from the receiving object can be shortened, thereby reducing the generation of dust. Secondly, the bendability of the bellows 9 can facilitate the user to adjust the material landing area.

[0034] See also Figure 1 、 Figure 2 and Figure 3 A conveying shaft 12 is rotatably connected between the left and right inner walls of the conveying cylinder 6, and an auger blade 13 is fixedly connected to the outer surface of the conveying shaft 12. Through the setting of the auger blade 13, the purpose of pushing the grain can be achieved.

Through the setting of the motor 14, power can be provided for the rotation of the conveying shaft 12.

[0035] See also Figure 1 、 Figure 2 and Figure 3A height sensor 16 is installed at the left end of the conveying cylinder 6. Through the setting of the height sensor 16, the user can easily control the height of the discharge pipe 8. A control host 17 is installed on the upper surface of the shock-absorbing plate 2. The motor 14, the hydraulic rod 11 and the height sensor 16 are all electrically connected to the control host 17. Through the setting of the control host 17, the purpose of controlling the electrical components can be achieved.

[0036] A screw conveying device in this embodiment significantly improves the shock absorption effect through the combined design of the shock absorbing plate 2, the buffer rod 3, the spring 4 and the damper 5. The addition of the damper 5 effectively reduces the impact when the spring 4 is reset, so that the device can run more smoothly when subjected to external force, thereby improving the conveying stability and the conveying quality of the material. A bellows 9 is added at the bottom of the discharge pipe 8. This design makes it easy for the user to adjust the length of the bellows 9 according to different receiving containers, reducing the dust diffusion problem caused by the large drop in the grain during the conveying process. The bendability of the bellows 9 also provides the user with the flexibility to adjust the material landing area. The hydraulic rod 11 has the function of adjusting the height of the left end of the conveying cylinder 6. The user can adjust the inclination angle and height of the conveying cylinder 6 according to actual needs, further expanding the application range of the device and improving its practical value.

[0037] The working principle of the above embodiment is as follows: first, the device is moved to the designated working position by the multiple moving wheels 10 at the bottom of the base plate 1. Before starting, the user can adjust the length of the hydraulic rod 11 by controlling the host 17 as needed, thereby changing the height of the left end of the conveying cylinder 6 and adjusting the tilt angle of the conveying cylinder 6 to meet different conveying requirements. When the grains are pushed to the discharge pipe 8, the combined design of the shock absorbing plate 2, the buffer rod 3, the spring 4 and the damper 5 plays an important role in the conveying process. When the device is subjected to external force or vibration occurs during the conveying process, the shock absorbing plate 2 first absorbs part of the impact force, and then the buffer rod 3 is used to adjust the impact force. The elastic deformation of the spring 4 further cushions the vibration. In particular, the presence of the damper 5 effectively reduces the impact when the spring 4 is reset, so that the entire device can return to its original position more smoothly after being subjected to external force, reducing the shaking of key components such as the screw rod, and ensuring the stability of transportation. Through the design of the bellows 9, the grains can fall smoothly into the receiving container. The bellows 9 not only reduces the distance between the discharge port and the receiving container, reducing the dust diffusion problem caused by the large drop, but also because of its bendability, allows the user to adjust the length and bending direction of the bellows 9 according to the position of the receiving container, thereby flexibly adjusting the landing area of the material.
