Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a tractor-mounted peanut harvester header. Background Technology

[0002] With the development of social technology, agricultural machinery is being used more widely in agricultural operations. Currently, peanut harvesters are generally divided into two categories: self-propelled peanut harvesters and towed peanut harvesters. Self-propelled harvesters are self-powered, and their cost is relatively high; towed peanut harvesters utilize the power of a tractor, and the tractor and implements are connected through a traction transmission mechanism.

[0003] At present, there are the following technical problems with tractor-driven peanut harvesters: (1) The power input shaft on the cutter head is connected to the power output shaft of the traction equipment through a universal joint. Since the maximum working angle of the universal joint is limited, if the turning angle is greater than the maximum working angle during turning operations, the universal joint is easily damaged. Therefore, the tractor needs to maintain a large turning radius when turning. If a large working angle is required, the output power needs to be cut off before turning, and the output power needs to be given again after turning. This operation is cumbersome and not conducive to improving work efficiency. (2) The angle adjustment of the cutter head is inconvenient. Due to the unevenness of the farmland ground, the regional adaptability is poor. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tractor-mounted peanut harvester header that can achieve free steering at large angles and has convenient header angle adjustment.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a traction peanut harvester header, including a frame and a traction frame, wherein a pickup is installed at the front end of the frame; a traction shaft is installed on the frame, and a traction sleeve is installed on the traction frame, wherein the traction sleeve is rotatably fitted onto the traction shaft; and an angle adjustment drive mechanism is installed between the frame and the traction frame to drive the frame to rotate around the traction shaft.

[0006] As a preferred technical solution, the traction frame includes a front traction arm, a rear traction arm, and a mounting frame; the front traction arm and the rear traction arm are rotatably connected by a transition assembly, the rear traction arm is fixedly connected to the mounting frame, and the mounting frame is fixedly connected to the traction swivel via a traction fork plate.

[0007] As a preferred technical solution, a gearbox is installed on the traction frame. The gearbox includes an upper housing and a lower housing, which are rotatably connected. A power input shaft is rotatably installed in the lower housing, and a power output shaft is rotatably installed in the upper housing. A drive shaft is rotatably installed between the upper and lower housings, and the power input shaft and power output shaft are respectively connected to the drive shaft for transmission. The front traction arm is fixedly connected to the lower housing via a front connector, and the rear traction arm is fixedly connected to the upper housing via a rear connector.

[0008] As a preferred technical solution, the front connector includes two Z-shaped front traction plates, which are respectively fixedly installed on both sides of the lower housing.

[0009] As a preferred technical solution, the rear connector includes two Z-shaped rear traction plates, which are respectively fixedly installed on both sides of the upper housing.

[0010] As a preferred technical solution, the adapter assembly includes a connecting plate fixedly installed at the front end of the rear traction arm, a fixing plate installed on the connecting plate, and a traction shaft installed on the fixing plate; the rear end of the front traction arm is provided with a traction sleeve fitted onto the traction shaft, and the traction sleeve is rotatably connected to the traction shaft.

[0011] As a preferred technical solution, the tilt adjustment drive mechanism includes a drive cylinder, an upper mounting seat is provided on the frame, a lower mounting seat is provided on the mounting bracket, and the two ends of the drive cylinder are respectively hinged to the upper mounting seat and the lower mounting seat.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] (1) Since the frame is equipped with a traction shaft and the traction frame is equipped with a traction sleeve, the traction sleeve is rotatably fitted onto the traction shaft, and an angle adjustment drive mechanism is installed between the frame and the traction frame, the frame can be driven to rotate around the traction shaft through the angle adjustment drive mechanism, thereby realizing the adjustment of the cutting table angle. The structure is simple and reasonable, and the operation is convenient.

[0014] (2) Since the front traction arm and the rear traction arm are rotatably connected through the adapter assembly, the upper box and the lower box are rotatably connected, the front traction arm is fixedly connected to the lower box through the front connector, the rear traction arm is fixedly connected to the upper box through the rear connector, and a drive shaft is rotatably installed between the upper box and the lower box. The power input shaft and the power output shaft are respectively connected to the drive shaft for transmission. In this way, when towing agricultural implements, the lower box rotates with the front traction arm, and the upper box rotates with the rear traction arm, thereby achieving free steering at a large angle without affecting the normal transmission and output of power.

[0015] (3) The front traction arm is fixedly connected to the lower box through the front connector, and the rear traction arm is fixedly connected to the upper box through the rear connector. The front connector and the rear connector are Z-shaped structures. The bending shape of the Z-shaped structure makes it easy to connect, while enhancing the bending and torsional stiffness.

A tow shaft 15 is installed on the side plates 13. A tow sleeve 21 is installed on the tow frame 20, and the tow sleeve 21 is rotatably fitted onto the tow shaft 11. An angle adjustment drive mechanism 40 is installed between the frame 10 and the tow frame 20 to drive the frame 10 to rotate around the tow shaft 11. The angle adjustment drive mechanism 40 can drive the frame 10 to rotate around the tow shaft 11, thereby realizing the adjustment of the header angle. The structure is simple and reasonable, and easy to operate.

[0027] refer to Figures 1 to 4 The traction frame 20 includes a front traction arm 22, a rear traction arm 23, and a mounting frame 24; the front traction arm 22 and the rear traction arm 23 are rotatably connected by a transition assembly 25, the rear traction arm 23 is fixedly connected to the mounting frame 24, and the mounting frame 24 is fixedly connected to the traction sleeve 21 by a traction fork plate 26.

[0028] In this embodiment, the tilt adjustment drive mechanism 40 includes a drive cylinder 41, an upper mounting seat 42 is provided on the cover plate 14, and a lower mounting seat 43 is provided on the mounting frame 24. The two ends of the drive cylinder 41 are respectively hinged to the upper mounting seat 42 and the lower mounting seat 43.
