Description

Technical Field

[0001] This utility model relates to the field of harvester technology, specifically to a harvester header. Background Technology

[0002] With the advancement of technology and the development of science and technology, agricultural harvesters have been widely used to improve production efficiency. Harvesters can complete harvesting and threshing in one go, and collect the grains into the storage bin. Then, the grains are transported to the transport vehicle by the conveyor belt. They are integrated machines for harvesting crops, and the harvesting structure plays a crucial role in agricultural harvesters.

[0003] During harvesting, when the harvester is moving through the field, the front edge of the header may collide with the field ridge or some large stones, causing the harvester to be subjected to a rebound force, resulting in a poor driving experience for the driver and potential damage to the header, affecting the harvester's working efficiency. Secondly, the lever on the auger drum on the header guides the crop into the material outlet and into the bridge, but the lever on the auger drum often gets entangled with a large amount of straw, requiring the driver to stop the machine and clean it manually, affecting the use of the harvester.

[0008] 2. Technical Solution:

[0009] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0010] A header for a harvester, comprising:

[0011] The header assembly includes a header housing, a material inlet formed on the rear wall of the header housing, a divider uniformly fixed on the front end of the header housing, a reel rotatably mounted on the header housing, an auger conveyor rotatably mounted on the inner wall of the header housing, auger blades symmetrically fixed on the outer wall of the auger conveyor, levers uniformly mounted on the cylinder of the auger conveyor, and a bridge frame fixed on the outer wall of the header housing and connected to the material inlet.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] Figures 1-5 The diagram shown is a structural schematic of one embodiment of the header of a harvester according to this utility model. Please refer to [link / reference]. Figures 1-5 The present invention relates to a header for a harvester, the main body of which includes a header assembly 100, an anti-collision assembly 200, and an entanglement removal assembly 300.

[0033] The header assembly 100 includes a header housing 110, a material inlet 110a formed on the rear wall of the header housing 110, a divider 120 uniformly bolted to the front end of the header housing 110, a reel 130 rotatably mounted on the header housing 110, an auger conveyor 140 rotatably mounted on the inner wall of the header housing 110, and auger blades 140a symmetrically welded and fixed to the outer wall of the auger conveyor 140. The auger blades 140a are symmetrically arranged on the outer wall of the auger conveyor 140. The auger blades 140a on both sides have opposite spiral directions, which allows the straw on both sides to be conveyed to the middle together. The levers 140b are evenly installed on the cylinder of the auger conveyor 140 and the bridge frame 150 is fixed on the outer wall of the header housing 110 and connected to the material inlet 110a. In some auger conveyors 140, the levers 140b are welded and fixed, while in others they are inserted into the cylinder of the auger conveyor 140 and can extend and retract relative to the cylinder. Their function is to push the straw into the material inlet 110a.

[0034] The anti-collision component 200 includes a hydraulic cylinder 210 symmetrically welded and fixed to the front end of the outer wall of the cutter housing 110; an oil chamber 220 opened inside the hydraulic cylinder 210, which stores hydraulic oil; an insertion hole 220a opened on the hydraulic cylinder 210 and connected to the oil chamber 220; a capillary tube 230 opened inside the hydraulic cylinder 210 and connected to the oil chamber 220, into which the hydraulic oil enters after being squeezed under high pressure; a buffer chamber 240 opened inside the hydraulic cylinder 210 and connected to the capillary tube 230, which buffers the external impact force during the process of the oil being squeezed from the capillary tube 230 into the buffer chamber 240, and then the oil returns to the oil chamber 220 to release pressure; a piston rod 250 passing through the insertion hole 220a; and a piston rod 250 fixed on the piston rod 250 and located in the oil chamber. The piston plate 260 in 220 and the protective sleeve 270, which is sleeved on the front end of the outer wall of the hydraulic cylinder 210 and fixed to the outer end of the piston rod 250, are used to ensure that when the front end of the cutting table side wall hits a hard object, the protective sleeve 270 is the first to be impacted because it is located on the outermost side. After being impacted, the protective sleeve 270 will drive the piston rod 250 and push the piston plate 260, causing the piston plate 260 to squeeze the hydraulic oil. The hydraulic oil, after being squeezed under high pressure, will enter the capillary tube 230 to buffer the force of the external impact. In addition, a limit groove 280 is opened on the front wall of the hydraulic cylinder 210, and a limit rod 290 is inserted into the limit groove 280. The limit rod 290 is fixed on the protective sleeve 270, so that the limit rod 290 is always inserted into the limit groove 280 during the movement of the protective sleeve 270, thereby preventing the protective sleeve 270 from tilting.

[0035] The entanglement removal assembly 300 is installed on the header housing 110 and can cut the straw entangled on the lever 140b. The entanglement removal assembly 300 includes a fixed base 310 welded to the top of the header housing 110, a horizontal plate 320 welded to the fixed base 310, a hydraulic cylinder 330 bolted to the horizontal plate 320, a motor base 340 threaded to the bottom of the hydraulic cylinder 330, a motor 350 bolted to the motor base 340, a rotating rod 360 coaxially connected to the output end of the motor 350, and a blade 370 bolted to the bottom of the rotating rod 360. The blade 370 is located between the two sets of levers 140b. When the blade 370 rotates, it will cut the long straw entangled on the lever 140b, reducing the entanglement.

[0036] Furthermore, in order to reduce the material adhering to the inner wall of the header housing 110, specifically, a threaded groove 160 is provided on the outer wall of the auger blade 140a, and a bolt 170 is engaged in the threaded groove 160. A scraper 180 is fixed to the outer end of the bolt 170. The scraper 180 can stick to the inner wall of the header housing 110. Because some damp material will stick to the inner wall of the header housing 110, when the auger blade 140a rotates, it will drive the scraper 180 to rotate along the inner wall of the header housing 110, so as to scrape off the material adhering to the inner wall of the header housing 110.

[0037] Finally, the device also includes a blockage-removing component 400, which is installed on the header housing 110 and can prevent blockage of material at the front end of the material inlet 110a. The blockage-removing component 400 includes a mounting groove 410 formed on the inner wall of the header housing 110 and located above the material inlet 110a, a guide rod 420 fixed in the mounting groove 410, a threaded rod 430 rotatably installed in the mounting groove 410, a lifting block 440 sleeved on the guide rod 420 and simultaneously meshing with the threaded rod 430, an L-shaped plate 450 fixed on the outer wall of the lifting block 440, and a mowing hook blade 46 fixed at the bottom end of the L-shaped plate 450. 0. The hook-shaped blade cuts materials more easily than a straight blade. This material generally refers to straw that is piled up and tangled together. The grass-cutting hook blade 460 is located at the front end of the material inlet 110a. The L-shaped plate 450 is fixed to the outer wall of the lifting block 440 by screws. The screws can be unscrewed to remove the grass-cutting hook blade 460 for easy replacement. In use, the height of the lifting block 440 and the grass-cutting hook blade 460 can be adjusted in advance by rotating the threaded rod 430. When a large amount of material is fed into the material inlet 110a, it will pass through the grass-cutting hook blade 460 first and be cut, thereby reducing blockage.

[0038] Combination Figures 1-5 The specific implementation of the header of this harvester is as follows:

[0039] 1. First, when the front side of the cutter housing 110 hits a hard object, the protective sleeve 270 will be hit first. After the protective sleeve 270 is hit, it will drive the piston rod 250 and the piston plate 260 to push the piston plate 260, causing the piston plate 260 to squeeze the hydraulic oil. After being squeezed by high pressure, the hydraulic oil will enter the capillary tube 230 to buffer the force of the external impact.

[0040] 2. Then, when straw is wrapped around the lever 140b, the hydraulic cylinder 330 is activated to move the blade 370 down to the lever 140b. The motor 350 is started to rotate the blade 370, so that the blade 370 can cut the wrapped straw and reduce the amount of straw wrapped around the lever 140b.

[0041] 3. Finally, before the material is fed into the material inlet 110a by the lever 140b, the material piled up will first pass through the grass-cutting hook blade 460, and then be cut by the grass-cutting hook blade 460 before entering the material inlet 110a, reducing the possibility of the material accumulating and clogging the material inlet 110a.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
