Description
Technical Field
[0001] This utility model relates to a lifting device for agricultural use. Background Technology
[0002] In agricultural production, screw conveyors (commonly known as "augers") are a common type of equipment used for vertical or inclined conveying of granular or powdery materials.
[0003] Traditional equipment typically has a high feeding port, requiring manual shoveling of materials from the ground before feeding them into the port. Frequent operation can easily cause fatigue and injury to the operator. Additionally, the need to swing the materials high each time can cause them to spill.
[0004] Based on the above problems, we designed an agricultural lifting device that facilitates feeding. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an agricultural lifting device that facilitates feeding.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] An agricultural lifting device includes a feed pipe, a rotating shaft rotatably mounted at the center of the feed pipe, spiral blades fixed on the rotating shaft, a discharge port near the top of the outer wall of the feed pipe, a feed port near the bottom of the outer wall of the feed pipe, and a drive motor for driving the rotating shaft to rotate installed at one end of the feed pipe. The device also includes…
[0008] A movable support structure is provided, through which the material tube is rotatably mounted to adjust the pitch angle of the material tube;
[0009] A rotary feeding device is rotatably installed at the feeding port. The rotary feeding device can be lowered to facilitate the addition of materials to be conveyed.
[0010] Preferably, the movable support structure includes a base plate and a support body. Two support bodies are provided at the front and rear. The lower end of the support body is fixed to the base plate. The material tube is installed between the front and rear support bodies. A connector is provided between the support body and the material tube. When the connector is tightened, the pitch angle of the material tube is fixed.
[0011] Preferably, the connector is a bolt, one end of which is fixed to the material tube, and the other end passes through the support body and is fitted with a nut.
[0012] Preferably, a plurality of rollers are provided at the bottom of the base plate, and a counterweight is provided at the top of the base plate in an inclined direction away from the material pipe.
[0013] Preferably, the rotary feeding device includes a feeding hopper, a hose, and an electric push rod. The electric push rod is connected to a controller that controls its extension and retraction. The electric push rod is rotatably connected between the feeding hopper and the support body. An installation tube is detachably installed at the upper end of the feeding port. Two rotating supports are symmetrically arranged on the outer wall of the installation tube. Ear plates are provided on the front and rear walls of the feeding hopper. Pins are fitted between the ear plates and the rotating supports. A connecting tube is provided at the bottom of the feeding hopper. The hose is fixed between the connecting tube and the installation tube.
[0014] Preferably, the connecting pipe is located at the left end of the bottom of the feeding hopper, and a material scoop is provided at the right end of the feeding hopper. When the electric push rod retracts, the material scoop rotates downward to near the ground.
[0015] Preferably, the feeding hopper has a bottom surface that slopes downward toward the connecting pipe.
[0016] Preferably, multiple support rods are provided inside the material collection part, a screen is installed inside the material collection part, a baffle is provided at the left end of the screen, the inner side of the screen is a screening chamber, fine particles enter the screening chamber after passing through the screen, a discharge port communicating with the screening chamber is provided at the bottom of the bottom surface of the material guide, and a discharge cover is provided at the discharge port.
[0017] The beneficial effects of this utility model are:
[0018] One advantage is that the movable support structure allows for adjustable tilt angles of the material tube, and the entire machine can be easily moved using the bottom rollers. This enables the equipment to quickly adapt to loading and unloading needs at different heights and positions, making it a versatile machine and greatly expanding its application scenarios.
[0019] The second advantage is the innovative rotary feeding device, which controls the downward rotation and lifting of the feeding hopper via an electric push rod. During feeding, the feeding hopper can descend to near the ground, greatly reducing the height and labor intensity of the feeding operation.
[0020] Thirdly, the tilt angle of the rotary feeder can be adjusted synchronously with the angle of the feed pipe, always ensuring that the discharge port of the feed hopper and the feed port of the feed pipe are in the best docking state, realizing the "tilt compensation" function, and effectively preventing feeding problems or blockages caused by unsuitable angles.
[0021] Fourthly, the integrated screen and screening chamber in the feeding hopper's hopper section can remove some fine particulate impurities (such as sand and debris) from the material during the feeding process. This design improves the cleanliness of the material at the source of the conveying process, reducing contamination and wear on subsequent conveying equipment and stored materials.

[0032] See Figure 1 and Figure 2 The illustrated agricultural lifting device includes a feed pipe 1, with a rotating shaft (not shown) rotatably mounted at the center of the feed pipe 1. A spiral blade (not shown) is fixed on the rotating shaft. The rotating shaft and the spiral blade are welded together, using standard agricultural dimensions. A discharge port 11 is located near the top of the outer wall of the feed pipe 1, and a feeding cylinder 111 is installed at the opening of the discharge port 11. The feeding cylinder 111 hangs downwards under gravity. A feeding port 12 is located near the bottom of the outer wall of the feed pipe 1. A drive motor 13 for driving the rotating shaft is installed at one end of the feed pipe 1. The device also includes…
[0033] The movable support structure 2 is used to rotate and install the material tube 1, thereby adjusting the pitch angle of the material tube; this allows for easy adjustment according to actual needs.
[0034] The rotary feeding device 3 is rotatably installed at the feeding port 12. After the rotary feeding device 3 is lowered, it is convenient to add the material to be conveyed.
[0035] The rotation of the rotary feeder 3 serves two purposes: first, it facilitates the addition of materials to be conveyed; second, it facilitates tilt compensation based on the inclination angle of the feed pipe 1, ensuring that materials can be input into the feed port 12 via the rotary feeder 3.
[0036] See Figure 3 As shown, the movable support structure 2 includes a base plate 21 and a support body 22. There are two support bodies 22 arranged at the front and rear. The lower end of the support body 22 is welded or bolted to the base plate 21. The material tube 1 is installed between the front and rear support bodies 22. A connector 23 is fitted between the support body 22 and the material tube 1. When the connector 23 is tightened, the pitch angle of the material tube 1 is fixed.
[0037] The connector 23 is a bolt, one end of which is welded and fixed to the material pipe 1, and the other end passes through the support body 22 and is fitted with a nut.
[0038] When the nut is tightened, the angle of the feed tube 1 is fixed.
[0039] See Figure 3 As shown, a plurality of rollers 24 are provided at the bottom of the base plate 21, and a counterweight 25 is provided at the top of the base plate 21 in an inclined direction away from the material tube 1.
[0040] In the above technical solution, the position of the entire lifting device can be flexibly changed as needed by setting the rollers 24.
[0041] The use of counterweight block 25 can achieve counterweight and prevent the material tube from tipping over.
[0042] See Figure 3 and Figure 4 As shown, the rotary feeding device 3 includes a feeding hopper 31, a hose 32, and an electric push rod 33. The electric push rod 33 is connected to a controller (not shown) that controls its extension and retraction. The electric push rod 33 is rotatably connected between the feeding hopper 31 and the support body 22. An installation tube 34 is detachably installed at the upper end of the feeding port 12. Two rotating supports 35 are symmetrically arranged on the outer wall of the installation tube 34. Ear plates 36 are provided on the front and rear walls of the feeding hopper 31. A pin 37 is fitted between the ear plates 36 and the rotating supports 35. A connecting tube 38 is provided at the bottom of the feeding hopper 31. The hose 32 is fixed between the connecting tube 38 and the installation tube 34.
[0043] In the above technical solution, the pitch angle of the feeding hopper 31 is adjusted by the extension and retraction of the electric push rod 33. When the end of the feeding hopper 31 is facing down, it is convenient to add materials from the ground into the feeding hopper 31. After the addition is completed, the feeding hopper 31 is rotated to a horizontal position by the lifting of the electric push rod 33. The material in the feeding hopper is then sent into the material pipe 1 through the connecting pipe 38, the hose 32 and the installation pipe 34.
[0044] See Figure 4 As shown, the connecting pipe 38 is located at the left end of the bottom of the feeding hopper 31, and a material scooping part 331 is provided at the right end of the feeding hopper 31. When the electric push rod retracts, the material scooping part 331 rotates down to near the ground.
[0045] With the design of the material scooping part 331, when the feeding hopper 31 is tilted, the material can be scooped up by the material scooping part 331. Then, as the feeding hopper 31 gradually rotates to the horizontal, the material in the material scooping part 331 is laid into the feeding hopper 31 and finally sent into the feeding port 12.
[0046] See Figure 4 As shown, the feeding hopper 31 has a guide bottom surface 332 that slopes downward toward the connecting pipe.
[0047] The bottom surface 332 of the guide facilitates the conveying of materials towards the connecting pipe 38.
[0048] See Figure 4 As shown, multiple support rods 333 are provided inside the material collection part 331. A screen 334 is installed inside the material collection part 331. A baffle 335 is provided at the left end of the screen 334. The inner side of the screen 334 is a screening chamber 336. Fine particles (such as small stones) enter the screening chamber 336 after passing through the screen 334. A discharge port 337 communicating with the screening chamber 336 is provided at the bottom of the guide bottom surface 332. A discharge cover 338 is provided at the discharge port 337.
[0049] In the above technical solution, when the material is put into the feeding hopper 31, some fine particles can be screened out by the screen 334. As the feeding hopper 31 gradually tilts, the material rolls down along the screen 334, and some fine particles are screened out during the rolling process, which improves the cleanliness of the material during storage.
