Description

Technical Field

[0001] The utility model relates to the technical field of straw walkers, in particular to a key surface of a straw walker for a harvester. Background Art

[0002] The straw walker is a part of the harvester. It harvests and discharges crop stalks relatively intact and has good recyclability. Therefore, the straw walker harvester has become the first choice in areas with developed animal husbandry. The working principle of the straw walker is that the key and the crank form a parallel four-bar linkage, and each point on the key surface makes the same circular motion as the crank; the key shakes up and down, the stalks are thrown, and the seeds are separated;

[0003] Publication No. CN208480293U discloses a vibrating screen box shaker for a peanut harvester. By adding a second shaker sheet between a shaking plate and a first shaker sheet, and the density of the second shaker sheet is greater than that of the first shaker sheet, and the length is shorter than that of the first shaker sheet, it is beneficial for the device to effectively push peanuts and crushed fruit vines to the rear evenly during actual use, which not only reduces the cleaning workload of the front end of the vibrating screen but also transports them to an effective wind speed cleaning area, thereby reducing the blockage of the vibrating screen and improving the cleaning effect;

[0004] However, the above-mentioned straw shaker for crop vibration in the harvester still has the following problems during actual use: the crops are vibrated and screened by the first straw shaker piece and the second straw shaker piece inside the single straw shaker cooperation device, but in actual operation, the single straw shaker cannot generate the limited power required for crop screening, and the crops partially covered underneath are difficult to break away from the contact with the straw shaker during vibration, and the single straw shaker cannot form front and rear misalignment and lateral height difference, which leads to inadequate vibration and screening of the crops.

[0005] Therefore, we propose a harvester straw walker key surface to solve the problems raised above. Utility Model Content

[0006] The utility model aims to provide a key surface of a harvester straw walker to solve the problem proposed in the above-mentioned background technology that crops are vibrated and screened by first and second straw walker sheets inside a single straw walker cooperation device, but in actual operation, a single straw walker cannot form a limited power required for crop screening, and crops partially pressed underneath are difficult to break away from the contact with the straw walker during vibration and screening, and a single straw walker cannot form front-to-back misalignment and lateral height difference, which leads to inadequate vibration and screening of crops.

[0007] To achieve the above object, the utility model provides the following technical solution: a harvester straw walker key surface, comprising a straw walker body distributed at equal distances, and a screening partition plate fixedly arranged at equal distances on the inner top surface of the straw walker body;

[0013] Preferably, the top surface level of the walker body is lower than the top surface level of the anti-slip side plates, and the anti-slip side plates arranged at equal distances are located on the stepped top surface of the walker body, and the anti-slip side plates arranged at equal distances prevent crops from sliding outward.

[0014] Preferably, driving crankshafts are rotatably arranged on both the front and rear sides of the bottom of the draft walker body which are arranged equidistantly, and the middle part of the driving crankshaft is rotatably connected to the bottom of the traction cross plate on the front and rear sides of the bottom of the draft walker body through a bearing, and when the driving crankshaft rotates to a vertical state, the draft walker bodies which are arranged equidistantly are driven to be distributed in an up-and-down staggered state.

[0015] Preferably, when the driving crankshaft rotates in a horizontal state, it drives the equally spaced straw remover bodies to be distributed in a front-to-back staggered state, and the rotation directions of the front and rear driving crankshafts are the same, and the rotation of the driving crankshaft causes the crops on the surface of the driving crankshaft to gradually jump backwards.

[0016] Preferably, the first draft-removing pieces and the second draft-removing pieces included in the key surface mechanism are equidistantly distributed, and the equidistantly arranged first draft-removing pieces and the second draft-removing pieces are fixedly installed on the upper part of the interior of the draft remover body, and the gap between adjacent first draft-removing pieces and second draft-removing pieces facilitates the downward discharge of fine particles.

At the same time, the feeding trough holes opened at equal distances can also assist in the screening of crop seeds;

[0020] 3.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem that the existing walker body 1 cannot form a sufficient height difference, this embodiment adopts the following technical solution, by connecting the traction cross plates 5 and the driving crankshaft 9 inside the walker body 1 which are evenly distributed, and the rotation of the driving crankshaft 9 drives the rotation of the connected traction cross plates 5 and the walker body 1, so that the multiple walker bodies 1 are in a state of reciprocating front-to-back misalignment and up-and-down misalignment during the movement, so as to provide sufficient separation space for the vibration screening of crops;

[0032] A harvester straw walker key surface comprises a straw walker body 1 which is equidistantly distributed, an anti-slip side plate 3 is arranged on the outer side of the top of the straw walker body 1 which is equidistantly arranged, and the anti-slip side plates 3 which are equidistantly arranged are distributed in an inclined structure; a feeding cavity 4 is opened inside the straw walker body 1 which is equidistantly arranged, and a traction cross plate 5 is fixedly arranged on both sides of the front and rear of the feeding cavity 4 inside the straw walker body 1 which is equidistantly arranged;

[0033] The front and rear sides of the bottom of the equidistant draft walker body 1 are both rotatably provided with a driving crankshaft 9, and the middle part of the driving crankshaft 9 is rotatably connected to the bottom of the traction cross plate 5 on the front and rear sides of the bottom of the draft walker body 1 through a bearing, and when the driving crankshaft 9 rotates to a vertical state, the equidistant draft walker bodies 1 are driven to be distributed in an up-and-down staggered state;

[0034] When the driving crankshaft 9 rotates in a horizontal state, the straw walker bodies 1 arranged at equal distances are driven to be distributed in a front-to-back staggered state, and the rotation directions of the driving crankshafts 9 on the front and rear sides are the same, and the rotation of the driving crankshaft 9 causes the crops on the surface of the driving crankshaft 9 to gradually jump backwards;

[0035] The horizontal height of the top surface of the walker body 1 is lower than the horizontal height of the top surface of the anti-slip side plates 3, and the anti-slip side plates 3 arranged at equal distances are located on the stepped top surface of the walker body 1, and the anti-slip side plates 3 arranged at equal distances prevent crops from sliding outwards;

[0036] like Figure 1 , Figure 4-Figure 5 As shown, the driving crankshafts 9 symmetrically distributed on the front and rear sides of the bottom of the straw walker body 1 are connected to the driving components inside the harvester, and the driving components drive the driving crankshafts 9 distributed on the front and rear sides to rotate in the same direction, so that the driving crankshafts 9 drive the connected traction cross plate 5 and the straw walker body 1 through the crank shafts distributed above and below. The adjacent straw walker bodies 1 will move from the front and rear misaligned state to the upper and lower misaligned state during the movement and continue to reciprocate, so that the crops above can be driven for vibration and screening. At the same time, the anti-slip side plates 3 distributed on the left and right sides of the outermost part effectively limit the vibration and screening of the crops to prevent the crops from slipping when they are in the air.

[0037] Embodiment 2: In order to enable the crops to move backward synchronously during the vibration and screening separation process, this embodiment adopts the following technical scheme, through the movement of the straw walker body 1 in a stepped shape from front to back, so that the crops above it move backward after being vacated, and cooperate with the screening partition 2 to prevent the crops from moving in the opposite direction, and at the same time, the feeding trough holes 8 opened at equal distances can also assist in the screening of crop seeds;

[0038] Screening partitions 2 are fixedly arranged at equal distances on the inner top surface of the walker body 1; the walker body 1 distributed at equal distances is arranged in a stepped shape from front to back as a whole, and the rear of the walker body 1 is arranged in a downwardly inclined structure, and the adjacent parts of the step-shaped walker body 1 are closed by the screening partitions 2;

[0039] The equidistantly arranged sub-screening partitions 2 are all provided with feeding slots 8 inside, and the equidistantly arranged sub-screening partitions 2 realize downward discharge of fine particles through the feeding slots 8 provided inside, and the length of the equidistantly arranged feeding slots 8 is the same as the width of the walker body 1;

[0040] like Figure 3 , Figure 7 As shown, during the movement of multiple walker bodies 1, the movement direction from back to front drives the crops above to move synchronously backward during the process of vacating, thereby ensuring that the crops are transported from front to back. At the same time, the stepped walker body 1 cooperates with the screening partition 2 to prevent the crops from moving in the opposite direction. At the same time, the crop seeds dropped by the vibration screen will also roll to the screening partition 2. At this time, the discharge chute 8 opened inside the screening partition 2 facilitates the falling of the crop seeds, thereby preventing the inside of the walker body 1 from being blocked.

[0041] Embodiment 3: In order to solve the problem that crops easily block the straw walker body 1, this embodiment adopts the following technical scheme, and forms a hollow structure by a key surface mechanism arranged in the feeding cavity 4 inside the straw walker body 1, so that the debris and seeds separated from the crop stalks can fall downward through the gap between the first straw walker piece 6 and the second straw walker piece 7 inside the key surface mechanism, and cooperate with the upward wind force of the harvester to improve the vibration screening ability and anti-blocking ability of the straw walker body 1;

[0042] The interior of the draft remover body 1 which is arranged at equal distances is provided with a key surface mechanism, and the key surface mechanism which is arranged at equal distances includes a first draft remover piece 6 and a second draft remover piece 7 which are arranged at equal distances; the first draft remover piece 6 and the second draft remover piece 7 included in the key surface mechanism are arranged at equal distances, and the first draft remover piece 6 and the second draft remover piece 7 which are arranged at equal distances are fixedly installed on the upper interior of the draft remover body 1, and the gap between adjacent first draft remover pieces 6 and second draft remover pieces 7 facilitates the downward discharge of fine particles.

[0043] like Figure 1 , Figure 2 , Figure 6 As shown, during the movement of the straw walker body 1, it drives the crop stalks and seed debris on the surface to vibrate and screen. After screening, the debris and seeds fall into the inside of the key surface mechanism, and a gap is formed between the first straw walker piece 6 and the second straw walker piece 7 which are equidistantly distributed in the front and back and left and right shapes inside the key surface mechanism, so that the debris and seeds can fall quickly and be cleared with the upward wind force of the harvester to prevent the straw walker body 1 from being blocked.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
