Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and more particularly, to a split saddle-type rotatable grain tank and a harvester. Background Art

[0002] The grain tank is one of the important harvesting machines in agricultural machinery, and different specific structures of the grain tank are suitable for different harvesting processes.

[0003] There are two layout forms of the grain tank of the existing crawler harvester, the side-mounted type and the top-mounted type; for example, the structure of the side-mounted grain tank is disclosed in the patent of the combine harvester with a rotatable and removable grain tank device with the patent number 201220235894.9. The grain tank in this technical solution has a structure that can rotate unidirectionally on one side, but the grain bin is arranged on one side of the harvester; the main disadvantages of the side-mounted grain tank are that after the harvester is full of grain during operation, the center of gravity of the whole machine will shift to one side of the grain tank, resulting in the tilting of the harvester and the faults of getting stuck in the mud and overturning. The structure of the top-mounted grain tank is disclosed in the patent of the grain tank assembly and the harvester equipped with this grain tank assembly with the patent number 201811467910.5; the main disadvantages of the top-mounted grain tank are that after the harvester is full of grain during operation, the center of gravity of the whole machine will move upward. When crossing a ridge, one end of the harvester will tilt up, and the center of gravity will move forward and backward greatly, increasing the difficulty of crossing the ridge and even causing major accidents such as the overturning of the harvester.

[0004] Due to the above defects caused by the setting position of the grain tank, at present, due to the defects in the layout position of the grain tank of the crawler harvester, the volume of the grain tank can only be designed to be 1.4 to 1.7 cubic meters, and the limitation of the volume results in a very low operating efficiency of the grain tank.

[0005] In addition, the degree of freedom of disassembling the grain tank by unidirectional rotation or simultaneous bidirectional rotation is relatively low, and the maintenance process is relatively difficult, which easily leads to incomplete maintenance. And when closing, due to the inability to ensure the sealing performance, it is easy to cause the leakage of grains into the grain tank body, which easily causes the wear of the body by the grains or the problem that the body cannot perform operations. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a split saddle-type rotatable grain tank and a harvester for the problems of low efficiency of the crawler harvester and the weakening of the ability to pass through muddy land caused by the offset of the center of gravity.

[0007] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] The present invention provides a split saddle-type rotatable grain tank, including two side boxes, and any one of the side boxes can independently rotate in a direction away from or close to the other side box. The opposite side walls of the two side boxes are both open, and the two side boxes can be rotated to a closed state where the opposite side walls are in contact with each other and communicate.

[0009] The technical solution of the present invention has the beneficial effect that by the independent rotation of any side box body, the opening and closing of the grain box can be realized. During use, the position of the center of gravity will not change with the storage or unloading of grains, so that it has a larger volume compared with the grain boxes in the prior art. In addition, the grain box can perform maintenance and repair on any side box body according to actual needs. In the closed state, since the side walls of the two side box bodies are in contact with each other, the gap between them is avoided, preventing the grains from entering the space between the two side box bodies, which may cause wear or failure of the grain box.

[0010] Further, fastening connectors are provided on the opposite side walls between the two side box bodies. In the closed state, the two side box bodies are tightly connected to each other through the fastening connectors.

[0011] The beneficial effect of adopting the above further solution is that the two side box bodies can be tightly connected in the closed state, further preventing the leakage of grains.

[0012] Further, each side box body is provided with a detachable pull rod, and each pull rod provides a pulling force towards the other side box body for the corresponding side box body.

[0013] The beneficial effect of adopting the above further solution is that the two side box bodies can be stably connected in the closed state, preventing the two side box bodies from separating from each other possibly.

[0014] Further, at least one open edge of the opposite side walls of the two side box bodies is provided with a sealing strip.

[0015] The beneficial effect of adopting the above further solution is that the sealing performance between the two side box bodies in the closed state is further improved.

[0016] Further, a grain inlet for material input is provided at the upper part of one of the side box bodies, and the grain inlet can be flipped relative to a side wall of the side box body where it is located.

[0017] The beneficial effect of adopting the above further solution is that the detachable freedom degree of the grain box is further improved.

[0018] Further, the grain inlet is fixedly connected to the grain input device, and the grain input device extends into the grain inlet.

[0019] The beneficial effect of adopting the above further technical solution is that the grains enter the grain inlet through the grain input device and then enter the grain boxes on both sides.

[0020] Further, the grain input device and the grain inlet are hermetically connected through a sealing plate.

[0021] The beneficial effects of adopting the above further technical solution are as follows: The connection between the grain input device and the grain inlet is sealed, and the airtightness of the grain box is further improved.

[0022] Further, a grain outlet is respectively arranged on the front side of each of the side boxes; the two grain outlets are respectively fixedly connected to the grain unloading mechanism.

[0023] The beneficial effects of adopting the above further technical solution are as follows: The grain unloading mechanism can receive the grains unloaded from the grain outlet, realizing the unloading and transfer of the grains.

[0024] Further, fixing devices are arranged on the rear sides of the two side boxes, and each side box is rotatably connected to the fixing device.

[0025] The present invention provides a harvester, including a grain box, and the grain box is the split saddle-shaped rotatable grain box as described above.

[0026] The beneficial effect of the above technical solution lies in that by setting the split saddle-shaped rotatable grain box, its center of gravity can be kept unchanged, solving the problems of soft ground and weakened passing ability on the ridge of the crawler harvester, and the operation efficiency is increased by more than 20% compared with the existing one, greatly breaking through the efficiency problem of the existing crawler machine.

[0039] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0040] As Figures 1 to 4 shown, a split saddle-type rotatable grain box includes two side boxes 1. Any one of the side boxes 1 can independently rotate in a direction away from or close to the other side box 1, and the two side boxes 1 can be rotated to a closed state where the opposite side walls are in contact with each other; the inner diameter of the upper part of each side box 1 is larger than that of the lower part, and the shape of the connection between the upper part and the lower part is funnel-shaped. The opposite side walls of the upper parts of the two side boxes 1 are in an open form. In the closed state, the open opposite side walls between the two side boxes 1 are in contact, so that the upper parts of the two side boxes 1 are communicated; by independently rotating any one of the side boxes 1, the opening and closing of the grain box can be realized. During use, maintenance and repair of any one of the side boxes 1 can be carried out according to actual needs; at the same time, in the closed state, since the side walls of the two side boxes 1 are in contact with each other, the gap between them is avoided, preventing the grain box from being worn or malfunctioning due to grains entering the space between the two side boxes 1.

[0041] The positions of the axes around which the two side boxes 1 of the present invention rotate can be located on the front and rear sides of the rotatable grain box respectively, or can be located on the front side and the rear side at the same time.

[0042] In an embodiment of the present invention, fixing devices are provided on the rear sides of the two side boxes 1, and each side box 1 is rotatably connected to the fixing device respectively.

[0043] In the above embodiment, preferably, the fixing device is a column 2, and each side box 1 is rotatably installed on a column 2; a connecting rod 12 is fixed between the two columns 2, and the connecting rod 12 can fix the positions between the two columns 2, so that the two side boxes 1 can rotate around the columns 2 stably; and in the closed state, the connecting rod 12 can make the contact between the two side boxes 1 closer.

[0044] In the above embodiment, preferably, the side box 1 and the column 2 are connected through a rotating connecting member, and the rotating connecting member includes but is not limited to one of a hinge, a torsion spring, and a rotating bearing; further preferably, the side box 1 and the column 2 are rotatably connected through a hinge.

[0045] On the opposite side walls between the two side boxes 1 of the present invention, fastening connectors are provided. In the closed state, the two side boxes 1 are tightly connected to each other through the fastening connectors.

[0046] The above-mentioned fastening connectors include, but are not limited to, snap connectors, pins, and buckling connectors.

[0047] In an embodiment of the present invention, the fastening connector is a buckle 3; buckle 3 is provided on the upper edges of the opposite side walls between the two side boxes 1, and the two side boxes 1 are fixed to each other through the buckle 3; by providing the buckle 3, the two side boxes 1 in the closed state can be fixed to each other.

[0048] On each side box 1 of the present invention, a pull rod 5 is provided, and each pull rod 5 provides a pulling force towards the other side box 1 for the corresponding side box 1; in the closed state, the abutment between the two side boxes 1 is more stable and tight, further preventing grains from leaking between the two side boxes 1.

[0049] As Figure 5 shown, for the pull rod 5 of the present invention, the specific connection method includes, but is not limited to, any structure capable of maintaining the closed and abutting state of the two side boxes 1, specifically including the following two preferred embodiments: one end of the pull rod 5 is connected to the grain box 1, and the other end is connected to the fixed frame 9.

[0050] One preferred embodiment is that the two pull rods 5 are detachably connected.

[0051] Another preferred embodiment is that the two pull rods 5 are respectively detachably connected to other fixed mechanical structures connected to the rotating grain box, and the fixed positions are located between the two side boxes 1 in the closed state.

[0052] In the opposite side walls of the two side boxes 1 of the present invention, at least one side wall is provided with a sealing strip 13; in the closed state, the sealing strip 13 can further seal the abutment between the two side boxes 1.

[0053] In an embodiment of the present invention, a grain inlet 11 for material input is provided on the upper part of one of the side boxes 1, and the grain inlet 11 can be flipped relative to a side wall of the side box 1 where it is located; the grain inlet 11 is fixedly connected to the grain input device, and the grain input device extends into the grain inlet 11; so that grains enter the grain inlet 11 through the grain input device; since the grain box is in the closed state when grains are input, at this time the upper parts of the two side boxes 1 are communicated, and the grains input by the grain input mechanism can enter the two side boxes 1.

[0054] In the above embodiments, the edge where the grain inlet 11 abuts against the side box body 1 can achieve sealing, but this sealing does not affect its flipping relative to the side box body 1, nor does it affect the rotation of the side box body 1 itself.

[0055] In the above embodiments, preferably, the grain input device and the grain inlet 11 are hermetically connected through a sealing plate 43; the sealing plate 43 can prevent grains from leaking through the possible gaps at the connection between the grain cylinder 4 and the grain inlet 11.

[0056] In the above embodiments, preferably, the grain input device is a grain cylinder 4. The upper end of the grain cylinder 4 is a sprinkling port 41, and the lower end is fixedly connected to a conveying mechanism 42; the upper part of the grain cylinder 4 extends into any grain inlet 11, and the outer side wall of the grain cylinder 4 and the grain inlet 11 are hermetically fixed through a sealing plate 43; grains are conveyed into the grain cylinder 4 through the conveying mechanism 42 and are sprinkled through the sprinkling port 41.

[0057] In the above embodiments, preferably, the position of the sprinkling port 41 corresponds to the position where the openings of the two side box bodies 1 abut against each other, so that the grains sprinkled from the sprinkling port 41 can enter the two side box bodies 1 simultaneously.

[0058] In the above embodiments, preferably, there is a gap between the lower parts of the two side box bodies 1, and the lower part of the grain cylinder 4 and the conveying mechanism 42 are located in this gap.

[0059] In the above embodiments, preferably, the grain inlet 11 for the upper part of the grain cylinder 4 to extend can be flipped relative to any side wall of the side box body 1 where it is located; since the grain cylinder 4 extends into the grain inlet 11, when the side box body 1 on this side is opened, the grain cylinder 4 is likely to hinder its rotation; setting the grain inlet 11 on this side as a flipable structure, it can be first flipped outward relative to the side box body 1 to disengage the grain cylinder 4 from the side box body 1, and then the side box body 1 is rotated to enable the smooth opening of the rotating grain box.

[0060] In the above embodiments, preferably, the grain cylinder 4 is arranged vertically. On the side wall of the side box body 1 close to the grain cylinder 4 on the same side as the grain cylinder 4, there is a structure recessed into the side box body 1, and this recessed structure corresponds to the grain cylinder 4, so that the grain cylinder 4 can be accommodated in this recessed structure to prevent the side wall of the side box body 1 from hindering the vertical extension structure of the grain cylinder 4.

[0061] In the above embodiments, preferably, covers 15 are provided at the tops of the two grain inlets 11; buckles 3 are provided at the abutting positions of the mutually communicating side walls of the two grain inlets 11.

[0062] Each side box body 1 of the present invention is respectively provided with a grain outlet 14; each grain outlet 14 is fixedly connected with a grain unloading mechanism; the grain outlet 14 is located at the front side of the side box body 1, and the grain unloading mechanism corresponds to the positions of the two grain outlets 14.

[0063] In principle, the above-mentioned grain unloading mechanism includes various forms of grain unloading mechanisms. According to the specific structures of different grain unloading mechanisms, the specific connection methods between the grain outlet 14 and it are also different.

[0064] In an embodiment of the present invention, the grain unloading mechanism includes a grain unloading auger 6, a grain storage box 7 and a plurality of transmission gears 8; the grain storage box 7 is located below the two grain outlets 14, and the side walls at its ends are respectively communicated with the two grain outlets 14; the grain unloading auger 6 extends along the length direction in the grain storage box 7; the grains in the two side box bodies 1 enter the grain storage box 7 through the grain outlets 14, and move to one side of the grain storage box 7 under the rotation of the grain unloading auger 6, and there is an outlet on this side to unload the grains; there is a turnover mechanism in the two grain outlets 14, each turnover mechanism is rotatably fixed on the side wall of the grain outlet 14 through a shaft, and transmission gears 8 are arranged on the shafts of the two turnover mechanisms, and the transmission gears 8 are located outside the grain outlet 14; a transmission chain is sleeved on the two transmission gears 8, and the transmission chain can transmit power to enable the two turnover mechanisms to turn over. When the grains pass through the grain outlet 14, the turnover mechanism can stir and throw the grains to prevent the grains from being blocked in the grain outlet 14. A grain unloading jitter device is arranged in the side box body 1, and the jitter during the grain unloading process prevents the grains from accumulating in the box body and affecting the smoothness of grain unloading.

[0065] The present invention provides a harvester with a split saddle-type rotatable grain box, and the structure of the split saddle-type rotatable grain box is as described above.

[0066] Preferably, the harvester of the present invention is a crawler-type harvester. By setting a split saddle-type rotatable grain box, during the harvesting operation, when feeding and unloading grains, only the overall machine weight increases, and the center of gravity position will not change, breaking through the passing ability of the existing crawler-type harvesters on soft ground and ridges.

[0067] At the same time, the comprehensive operation time of the crawler-type harvester is T, the operation time during the grain feeding process is T1, and the auxiliary operation time during the grain unloading process is T2; in the prior art, T1 = 60%T, T2 = 40%T; for the harvester of the present invention, due to the unchanged center of gravity, the volume of the grain box can be designed to be larger. In an embodiment, the volume of the grain box is 5 cubic meters. At this time, T2 = T * 40% / 3, and the operation time during the grain feeding process is increased to T1 = T - T2 = 86.7%. That is to say, when the harvester equipped with a split saddle-type rotatable grain box unloads grains once, an ordinary harvester needs to unload grains three times; therefore, this harvester breaks through the efficiency limit of the existing crawler machines, generates great social benefits, and has great significance.

[0068] For the split saddle-shaped rotatable grain bin of the present invention, during maintenance and repair, the disassembly process of the two side boxes 1 is as follows:

[0069] Stop the operation of the harvester, close all working parts of the rotatable grain bin, and disassemble the grain unloading mechanism.

[0070] Disassemble the tie rod 5 to eliminate the tensile force on the two side boxes; open the cover plate 15 at the top of the grain inlet 11, and open the buckle 3 to release the abutment between the two side boxes 1.

[0071] Remove the sealing plate 43, and rotate the grain inlet 11 on this side outwards of the rotatable grain bin to disengage the grain cylinder 4 from the side box 1 on this side; then rotate the side box 1 on this side outwards to open the rotatable grain bin and expose its interior, so that maintenance and repair can be carried out.

[0072] According to actual needs, the side box 1 on the other side can also be further rotated and opened to increase the opening space of the rotatable grain bin and make maintenance and repair more convenient.

[0073] After maintenance and repair, perform the above steps in reverse order to close the rotatable grain bin.

[0074] For the split saddle-shaped rotatable grain bin of the present invention, by providing side boxes 1 that can rotate independently, the operation of the rotatable grain bin during maintenance and repair is more flexible, and any side box 1 can be opened according to the specific position that needs to be maintained and repaired, avoiding the problem in the prior art that the whole machine needs to be disassembled for maintenance. At the same time, the present invention is provided with a buckle 3, a tie rod 5 and a connecting rod 12, which can ensure the tightness of the abutment between the two side boxes 1. At the same time, a sealing strip 13 is also provided at the abutment to further increase the tightness, ensuring the tightness in the closed state while enabling the flexible rotation of the side box 1 and preventing mechanical failures caused by grains entering between the two side boxes 1.
