Abstract

The utility model discloses a feeding oat whole plant harvester which comprises a harvester body, a header is arranged at the front end of the harvester body, a U-shaped supporting frame is fixedly installed at the front end of the harvester body, a lifting mechanism is installed on the U-shaped supporting frame, the header is installed at the bottom of the lifting mechanism, and limiting wheels are installed at the bottom of the header. The lifting mechanism comprises a hydraulic cylinder, the hydraulic cylinder is installed at the top end of the U-shaped supporting frame, an elastic buffering assembly is installed at the bottom end of a telescopic rod of the hydraulic cylinder, and one end of the header is fixedly connected with a lifting block. Under the support of the limiting wheel, a certain distance between the header and soil can be ensured, so that the tail end of the header is prevented from being in contact with the soil to a certain extent, and harvested crops are ensured to be clean and tidy without being doped with the soil; due to the fact that the damper and the spring can contract, even if the tail end of the header makes contact with soil, the header ascends under the counter-acting force of the soil at the moment, contact with the soil is avoided, and it is further guaranteed that harvested crops are neat and not doped with the soil.

Description

Technical Field

[0002] Crop harvesting machines for harvesting grains and straws of crops such as rice and wheat include harvesters, swathers, binders, combine harvesters, and grain threshers, etc. Crop harvesting machines are developed on the basis of various harvesting and threshing tools. The front end of a crop harvester has a cutting table, and a reel and a divider are arranged on the cutting table.

[0003] The existing harvester adjusts the height of the cutting table through a hydraulic cylinder, and then adjusts the harvesting height of the crops. When harvesting the whole plant of the crops, since the height of the cutting table is very low, and there are many potholes and unevenness in the farmland, the end of the cutting table and the divider on it will contact the soil, which not only easily causes damage to the divider, but also makes the harvested oats contain soil.

Specific implementation mode

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe the implementation modes of the present utility model in detail with reference to the accompanying drawings.

[0025] Example 1, the present utility model provides a whole-plant oat harvester for feeding. Please refer to Figures 1-4 , which includes a harvester main body 1. A cutting table 3 is provided at the front end of the harvester main body 1. A U-shaped support frame 2 is fixedly installed at the front end of the harvester main body 1. A lifting mechanism is installed on the U-shaped support frame 2. The cutting table 3 is installed at the bottom of the lifting mechanism, and a limiting wheel 9 is installed at the bottom of the cutting table 3;

[0026] The lifting mechanism includes a hydraulic cylinder 4. The hydraulic cylinder 4 is installed at the top end of the U-shaped support frame 2. An elastic buffer assembly is installed at the bottom end of the telescopic rod 41 of the hydraulic cylinder 4. One end of the cutting table 3 is fixedly connected with a lifting block 31.

[0027] A wheel frame 91 is fixedly installed at the bottom of the end of the cutting table 3. The wheel frame 91 is rotationally connected with the limiting wheel 9 through a bearing. With the support of the limiting wheel 9, a certain distance can be ensured between the cutting table 3 and the soil, so that the end of the cutting table 3 is to a certain extent prevented from contacting the soil.

[0028] The elastic buffer assembly includes a damper 6 and a spring 7. The bottom end of the telescopic rod 41 is detachably installed with a first mounting plate 5. A damper 6 is fixedly installed at the bottom end of the first mounting plate 5. A spring 7 is sleeved outside the damper 6. The bottom end of the damper 6 is connected with the lifting block 31 through a second mounting plate 8.

[0029] The bottom of the damper 6 is welded with a second mounting plate 8. Internal threaded holes are respectively opened at the corresponding positions of the second mounting plate 8 and the lifting block 31. The second mounting plate 8 and the lifting block 31 are fixed through bolts.

[0030] A support connecting seat 51 is welded to the top end of the first mounting plate 5. The bottom end of the telescopic rod 41 is inserted into the support connecting seat 51. Internal threaded holes are respectively opened at the corresponding positions of the support connecting seat 51 and the telescopic rod 41. The support connecting seat 51 and the telescopic rod 41 are fixed through bolts; Since the damper 6 and the spring 7 can contract, even if the end of the cutting table 3 contacts the soil, at this time the cutting table 3 rises under the reaction force of the land, avoiding contact with the soil.

[0032] During specific use, supported by the limiting wheel 9, a certain distance can be ensured between the cutting table 3 and the soil, so that the end of the cutting table 3 is to a certain extent prevented from contacting the soil; since the damper 6 and the spring 7 can contract, even if the end of the cutting table 3 contacts the soil, at this time the cutting table 3 rises under the reaction force of the land, thus avoiding contact with the soil.

[0033] Embodiment 2, referring to the attached Figures 5-6 , different from Embodiment 2: A rolling groove 22 is provided on the inner wall of the U-shaped support frame 2, a support block 10 is welded on the outer wall of the lifting block 31, a wheel shaft 12 is rotatably connected to the support block 10 through a bearing, a roller 11 is fixedly installed on the wheel shaft 12, and the roller 11 contacts the inner wall of the rolling groove 22. Using the roller 11 can reduce the friction between the cutting table 3 and the U-shaped support frame 2.

[0034] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way, and the situations of these combinations are not exhaustively described in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
