Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a five-roller farmland stone gathering machine. Background Art
[0002] To improve the mechanization level of farming operations, it is necessary to remove the factors affecting mechanized operations in farmland soil for land preparation. In areas such as Altay, Yili, Tacheng, and Bortala in Xinjiang, China, the farmland contains a large amount of stones, and some cultivated lands are converted from forestland to farmland. In the converted farmland, tree branches and lignified rhizomes are difficult to decompose and rot. Debris such as stones, tree branches, and rhizomes in the farmland will affect the mechanized operations of crops and the growth and development of crops, resulting in low farming efficiency and low crop yields. Therefore, it is necessary to pick up debris such as stones, tree branches, and rhizomes in the farmland before tillage. Currently, a type of stone picker has emerged on the market. Such stone pickers all adopt a chain plate screening structure. When picking up stones, soil at a certain depth needs to be excavated together with the stones onto the screening and transmission chain, and the soil is returned to the field through vibration screening, and the screened stones are conveyed to the stone collection bin at the tail of the machine. However, such stone pickers have the following problems:
[0003] 1. In areas such as Altay, Yili, Tacheng, and Bortala in Xinjiang, the soil contains a large amount of stones with different particle sizes. Small stones are easily stuck in the chain drive system, causing equipment failures;
[0004] 2. The working width of such stone pickers is small, and the working efficiency is low. In the northern Xinjiang region, the farming season is tight, and there is not enough working time for stone picking operations, so they cannot be widely promoted and applied on a large scale and over a large area;
[0005] 3. The operating power consumption is large. Existing stone pickers need to excavate the entire soil within the operating depth onto the screening and transmission chain, resulting in high power consumption for the machine and poor operating economy.
[0006] 4. The reliability of the machine structure is not high, and it cannot meet the requirements of operating in a harsh working environment for a long time.
[0007] Therefore, the operating methods of existing stone pickers on the market are not suitable for use in Xinjiang. Content of the Utility Model
[0008] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a five-roller farmland stone gathering machine, which can screen debris in the farmland efficiently and in large quantities, and transmit and gather the debris to the first gathering end of the side rake roller to form ridges. It is not necessary to excavate and screen the entire soil within the working width, the operating energy consumption is reduced, the operating economy is good, and it is suitable for use in large areas of farmland in Xinjiang.
[0009] The specific technical solution adopted by the utility model is:
[0010] A five-roller farmland stone collecting machine, comprising a frame and a stone picking device arranged on the frame. The stone picking device includes a set of side rake rollers rotatably arranged on the left and right sides of the frame. Rake teeth are arranged on the side rake rollers, and the rake teeth are respectively arranged around the surface of the side rake rollers and along the spiral direction. The side rake rollers include a first collecting end and a first overhanging end. The first overhanging end overhangs outward from the first collecting end towards the outside of the frame and is inclined forward along the advancing direction of the frame. The stone picking device forms a continuous stone picking area in the farmland as the frame moves forward.
[0011] The side rake rollers are symmetrically arranged on both sides of the frame and form a flared structure along the advancing direction of the frame. The stone picking device further includes an intermediate roller arranged on the frame and located within the flared structure. Rake teeth are arranged on the surface of the intermediate roller, and the working areas of the intermediate roller are respectively connected with the working areas of the side rake rollers to form a continuous stone picking area.
[0012] The intermediate roller is inclined along the advancing direction of the frame, and the rake teeth are arranged around the surface of the intermediate roller and along the spiral direction.
[0013] Pairs of side rake rollers are respectively arranged on the left and right sides of the frame, and the pairs of side rake rollers are arranged in sequence along the advancing direction of the frame.
[0014] The side rake rollers are respectively connected to the frame by means of a traction frame, and one end of the traction frame is hinged to the frame. An angle telescopic cylinder connected to the traction frame is arranged on the frame. The traction frame has the freedom to swing on the frame by means of the telescopic movement of the angle telescopic cylinder.
[0015] A main depth-limiting wheel and an auxiliary depth-limiting wheel are respectively arranged on the frame. The main depth-limiting wheel is arranged in a matching manner with the end of the frame, and the auxiliary depth-limiting wheels are respectively arranged in a matching manner with the traction frames.
[0016] A height telescopic cylinder hinged to the main depth-limiting wheel is arranged on the frame. The main depth-limiting wheel has the freedom to adjust its height on the frame by means of the telescopic movement of the height telescopic cylinder.
[0017] The beneficial effects of the present utility model are:
[0018] In the present utility model, side rake rollers and an intermediate roller with rake teeth are used to turn and rake the soil in the farmland. The spiral arrangement of the rake teeth has a high transfer efficiency for transmitting sundries, has a simple structure, high reliability, is not easily jammed, and can meet the operation requirements in a harsh working environment for a long time;
[0019] The side rake rollers overhang towards both sides of the frame respectively, effectively increasing the width of the stone picking operation and improving the working efficiency;
[0020] When the side rake roller and the middle roller rotate and work, sundries such as stones and branches within the working depth are raked out of the ground under the knocking action of the rake teeth. Large pieces of soil are broken, improving the soil preparation quality. The soil and small fragments pass through the gaps between the rake teeth and remain in place, without the need to excavate and screen the soil as a whole within the width of the operation area, reducing the power consumption of the useless work of stone picking. The sundries are then transmitted to the first strip collecting end of the side rake roller along the helically arranged rake teeth, efficiently completing the stone picking operation and at the same time realizing the collection and ridging of sundries;
[0021] On the other hand, during the repeated knocking process between the rake teeth and the soil, the sundries can be pushed out between the rake teeth, and jamming is not likely to occur, effectively avoiding equipment failures caused by the jamming of sundries.
[0022] The side rake roller and the middle roller cooperate to form a continuous stone picking area, realizing the comprehensive stone picking operation of the farmland, avoiding missed raking within the operation area, and further improving the working efficiency and soil preparation quality.

DETAILED DESCRIPTION OF THE INVENTION
[0027] The present utility model will be further described below in conjunction with the drawings and specific embodiments:
[0028] Specific embodiments are as Figures 1-3 shown. A five-roller type farmland stone collecting machine includes a frame 1 and a stone picking device arranged on the frame 1. The stone picking device includes a group of rotatable side rake rollers 2 arranged on the left and right sides of the frame 1. Rake teeth 3 are arranged on the side rake rollers 2, and the rake teeth 3 are respectively arranged around the surface of the side rake rollers 2 and along the helical direction. The side rake rollers 2 include a first strip collecting end 4 and a first overhanging end 5. The first overhanging end 5 overhangs from the first strip collecting end 4 outside the frame 1 and is inclined forward along the forward direction of the frame 1. The stone picking device forms a continuous stone picking area 6 in the farmland as the frame 1 moves forward.
[0029] Among them, the frame 1 is connected to the tractor, and the engine on the tractor provides power for the stone-picking device to drive the stone-picking device to work. The setting of the side rake roller 2 effectively expands the width of the stone-picking operation, with fewer limiting factors for the working width, achieving a large-width operation, and being suitable for high-efficiency operation conditions with a large area and tight farming seasons.
[0030] The relationship between the rotation direction 14 of the side rake roller 2 located on the left side of the frame 1 and the transmission direction 13 of the side rake roller 2 is as Figure 3 shown. As the frame 1 moves forward, the rake teeth 3 on the side rake roller 2 on the left side of the frame 1 rake out sundries from the soil from the back to the front, and are conveyed along the transmission direction 13 to the first strip end 4 by the push of the rake teeth 3.
[0031] During operation, the tractor drives the frame 1 to move along the forward direction 12. The side rake roller 2 simulates the operation of using a rake by hand to rake the land. The rotating side rake roller 2 can continuously turn over the soil, turning over sundries such as stones, branches, and rhizomes in the soil to the surface. The soil and smaller lumps leak out from the gaps between the teeth of the rake teeth 3, reducing the power consumption of useless work in the stone-picking operation. The rake teeth 3 can also break large soil lumps, improving the quality of land preparation operations. The helically arranged rake teeth 3 can quickly transfer the raked sundries, causing the sundries to move along the transmission direction 13 to the first strip end 4 of the side rake roller 2. With the traction of the tractor, the sundries are discharged from the first strip ends 4 of the two side rake rollers 2 onto the same belt, thus realizing the collection of sundries into ridges.
[0032] The stone-picking device forms a continuous stone-picking area 4 as the frame 1 moves, and can perform a complete stone-picking operation on the area passed by the stone stripper, avoiding missed picking and causing stones to be buried in the soil.
[0033] The side rake rollers 2 are symmetrically arranged on both sides of the frame 1 and form a flared structure along the forward direction of the frame 1. The stone-picking device further includes an intermediate roller 7 provided on the frame 1 and located within the flared structure. The surface of the intermediate roller 7 is provided with rake teeth 3, and the working areas of the intermediate roller 7 are respectively connected to the working areas of the side rake rollers to form a continuous stone-picking area 6.
[0034] The intermediate roller 7 turns over and rakes the area that cannot be reached between the side rake rollers 2 on the left and right sides of the frame 1, turning over the sundries to the soil surface, achieving a comprehensive stone-picking operation on the farmland, avoiding missed raking in the operation area, and further improving work efficiency and land preparation quality; the sundries raked out by the side rake rollers 2 on both sides of the frame 1 and the intermediate roller 8 are gathered into a single ridge, reducing the occupied area and the degree of dispersion of the sundries.
[0035] The further intermediate roller 7 is inclined along the advancing direction of the frame 1. The rake teeth 3 are arranged around the surface of the intermediate roller 7 and along the spiral direction. The intermediate roller 7 conveys the sundries raked out by it to one side. In this embodiment, the rear end of the intermediate roller 7 is the second strip collecting end, and the front end is the second overhanging end. The second overhanging end is connected to the working area of the side rake roller 2 on one side of the frame 1, and the second strip collecting end is connected to the working area of the side rake roller 2 on the other side of the frame 1. The intermediate roller 7 conveys the sundries raked out to the second strip collecting end, and integrates them with the sundries output from the first strip collecting end 4 of the side rake roller 2 into a ridge. The included angle α between the intermediate roller 7 and the advancing direction 12 is greater than the included angle β between the side rake roller 2 and the advancing direction 12.
[0036] Paired side rake rollers 2 are respectively arranged on the left and right sides of the frame 1, and the paired side rake rollers 2 are arranged in sequence along the advancing direction of the frame 1, that is, two side rake rollers 2 arranged in sequence front and back are respectively arranged on the left and right sides of the frame 1. The working areas of the paired side rake rollers 2 overlap each other to realize repeated raking of the farmland soil, prevent sundries from remaining in the farmland soil, and repeated raking of the soil can effectively reduce the existence of large soil blocks, make the soil more finely divided and loose, and improve the soil preparation quality. The side rake roller 2 and the intermediate roller 7 form a five-roller stone picking device to fully pick up and gather the sundries in the farmland soil.
[0037] The side rake rollers 2 are respectively connected to the frame 1 by means of the traction frame 8, and one end of the traction frame 8 is hinged to the frame 1. An angle expansion and contraction cylinder 9 connected to the traction frame 8 is arranged on the frame 1. The traction frame 8 has the freedom to swing on the frame 1 by means of the expansion and contraction of the angle expansion and contraction cylinder 9. The expansion and contraction of the angle expansion and contraction cylinder 9 can adjust the deployment angle of the side rake roller 2 on the frame 1. During work, the side rake roller 2 expands to both sides of the frame 1 by means of the change of the length of the angle expansion and contraction cylinder 10 to realize wide-width operation; after the work is completed, the side rake roller 2 is retracted to the frame 1 to reduce the overall width of the stone stripper, which is convenient for the storage of the stone stripper or its movement on the road.
[0038] A main depth-limiting wheel 10 and an auxiliary depth-limiting wheel 11 are respectively arranged on the frame 1. The main depth-limiting wheel 10 is arranged in a supporting manner at the end of the frame 1, and the auxiliary depth-limiting wheels 11 are respectively arranged in a supporting manner with the traction frame 8. During work, the main depth-limiting wheel 11 provides support for the frame 1, and the auxiliary depth-limiting wheel 12 provides support for the overhanging left roller 5 and right roller 6, limits the raking depth, and enables the stone stripper to work stably.
