Without creative effort, all other embodiments based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] This utility model discloses a high-efficiency loading and spreading device, such as... Figure 1 , Figure 2 As shown, it includes: The frame 10 has an axle 11 fixedly mounted at the rear. Wheels are coaxially mounted on the left and right ends of the axle 11. A footboard 12 and a seat plate 13 are fixedly mounted at the front of the frame 10. The footboard 12 is symmetrically arranged on the left and right sides of the frame 10, and the seat plate 13 is located at the center of the front of the frame 10. The upper surfaces of the footboard 12 and the seat plate 13 extend horizontally. An extension rod 14 is fixedly mounted at the center of the front end of the frame 10. A connecting seat 15 is hinged to the front end of the extension rod 14 and is used to connect with the traction vehicle. A support frame extends upward from the middle of the frame 10.

[0020] A hopper 20 is provided at the rear of the frame 10. The lower rear part of the hopper 20 is hinged to the frame 10. The lower front part of the hopper 20 is provided on the support frame. A lock is provided between the two. A hopper 21 is connected to the upper large opening of the hopper 20. An auger 22 is rotatably provided inside the hopper 21. A downwardly extending baffle 23 is symmetrically provided on the left and right sides of the lower small opening of the hopper 20.

[0021] An engine 30, fixed to the frame 10, is located in front of the hopper 20 and the bin 21. A transmission mechanism 31 is mounted on the engine 30, including a main drive shaft 311 connected to the power output of the engine 30. A front drive shaft 312 is located below the main drive shaft 311 via a pulley. A bevel gearbox is fixed to the frame 10 behind the front drive shaft 312. The bevel gearbox has a rear drive shaft 313 with its axis extending laterally and a longitudinal drive shaft extending rearward. The front drive shaft 312 is connected to the rear drive shaft 313 of the bevel gearbox via a pulley. A conveyor belt shaft 314 is located above the front drive shaft 312 and the rear drive shaft 313, and is connected to the rear drive shaft 313 via a pulley. A conveyor belt 32 is coaxially mounted on a rotating shaft 314. The conveyor belt 32 is spaced apart from the small opening at the lower end of the hopper 20. The conveyor belt 32 is positioned between the baffles 23 on the left and right sides and extends backward. A gearbox 33 is mounted on the other end of the conveyor belt rotating shaft 314 via a pulley. A tensioning rod assembly 34 is mounted on the transmission belt between the two. The tensioning rod assembly 34 consists of two tensioning rods with adjustable axial spacing. The gearbox 33 is fixedly mounted at the front end of the hopper 21 and is connected to the auger 22. A material spreading turntable 35 and a guide plate 36 are mounted at the rear end of the frame 10. The material spreading turntable 35 is positioned below and behind the conveyor belt 32. The material spreading turntable 35 is connected to the rotating shaft or longitudinal transmission shaft of the wheel on the axle 11 via a universal joint. The guide plate 36 is symmetrically positioned on the left and right sides of the guide plate 36.

[0022] Based on the specific structure of the high-efficiency loading and spreading device in the above embodiments, its working process will be further explained below: Before starting the material spreading operation, the frame 10 is connected to the towing vehicle via the connecting seat 15.

[0023] The material to be spread is loaded into the hopper 21, and the material falls into the hopper 20 under the action of gravity. Start the engine 30, which drives the main drive rotation 311 to rotate. The main drive rotation 311 drives the front drive shaft 312 to rotate. The front drive shaft 312 then drives the bevel gearbox via a pulley. The rear drive shaft 313 of the bevel gearbox rotates and drives the conveyor belt shaft 314 to rotate. The conveyor belt shaft 314 drives the conveyor belt 32 to rotate, so that the material at the small opening at the lower end of the hopper 20 is conveyed backward by the conveyor belt 32 until the material falls onto the rotating spreading turntable 35. Under the constraint of the left and right guide plates 36, the material is spread backward in a fan shape. The centrifugal force of the rotating spreading disc 35 is used to spread the material evenly, and the spreading range of the material is controlled by the guide plate 36, so that the material can be spread in a predetermined area, thereby improving the accuracy and uniformity of spreading.

[0024] The conveyor belt shaft 314 rotates and drives the gearbox 33 through the tension rod assembly 34. The gearbox 33 drives the auger 22 to rotate. The rotation of the auger 22 can assist the flow of materials in the hopper 21 and the hopper 20, prevent material blockage, and ensure that the materials can fall smoothly into the small opening at the lower end of the hopper 20 and be conveyed by the conveyor belt 32.

[0025] When the bevel gearbox is working, the longitudinal drive shaft rotates and drives the spreading turntable 35 to rotate at a constant speed through the universal joint. The speed ratio of the pulley in the transmission mechanism 31 is matched with the stirring speed of the auger 22 and the conveying speed of the conveyor belt 32.

[0026] The rotation of the wheel at the axle 11 drives the spreader turntable 35 to rotate via the differential and universal joint in the middle of the axle 11. The rotation speed of the spreader turntable 35 is proportional to the speed of the traction vehicle. Increasing the vehicle speed can expand the spreading range and improve the spreading efficiency.

[0027] In summary, the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification. All equivalent variations and modifications of the shape, structure, features, and spirit described in the claims of this utility model should be included within the scope of the claims of this utility model.
