Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a field reclamation and stone removal machine for agricultural planting. Background Art

[0002] For the reclamation and planting of wasteland, it is necessary to plow the wasteland, turn over the soil of the wasteland, and dig out weeds and stones. When reclaiming large farms, stones in the farmland are removed by using farmland stone pickers. The front end of the stone picker is usually a rolling shovel, and the stones are rolled and collected under the rolling action. However, large stone pickers are not suitable for agricultural plowing in hilly areas.

[0003] When reclaiming and planting farmland in hilly areas, a small tiller is usually used to turn the soil out, and then the tilled stones are picked up. Since the soil in hilly areas contains small stones, and when the tiller turns the soil, the stones will stick to a large amount of soil. By picking up and processing the stones, large stones mixed with soil will be processed, and small stones will still remain in the turned soil. This not only causes soil loss, but also makes it difficult to clean out small stones. For this reason, we propose a field reclamation and stone removal machine for agricultural planting.

DETAILED DESCRIPTION

[0023] 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 described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] See also Figure 1-7 The utility model provides a technical solution: a field reclamation and stone removal machine for agricultural planting, comprising a tilling frame 1 and a tilling roller 2 installed at the front end of the tilling frame 1, a plurality of curved tilling blades 3 are connected to the tilling roller 2, the cross section of the curved tilling blade 3 is triangular, and the front end of the curved tilling blade 3 is a cone, an assembly frame 1 is installed at the end of the tilling frame 1, the assembly frame 1 is used to connect with a tractor or a tilling machine body, and the tractor or the tilling machine body is driven on the wasteland to push the tilling roller 2 to till the soil. Since the front end of the curved tilling blade 3 is a cone, it is convenient to quickly insert it into the soil in the hilly area. At the same time, by designing the cross section of the curved tilling blade 3 to be triangular, on the one hand, it is convenient to cut the weeds in the soil with the cutting edge, and on the other hand, after the curved tilling blade 3 turns up the soil, the cutting edge cuts the turned-up soil, which is convenient for separating the soil.

[0025] A screening frame 4 is installed on the tilling frame 1, and the bottom of the screening frame 4 is higher than the curved part of the curved tilling blade 3; after the curved tilling blade 3 turns into the soil, the curved part is just slightly lower than the bottom of the screening frame 4. After the curved tilling blade 3 pulls out the soil, the turned over soil is thrown backward in a parabolic shape and just falls on the screening frame 4. At the same time, a pointed cone is arranged at the front end position of the screening frame 4, and the pointed cone is in a position parallel to the ground, so as to facilitate the dispersion of the thrown soil.

[0026] The top of the sieve shaking frame 4 is provided with an arc transition, and the bottom of the arc transition is hinged with a swing plate 5, and a rolling member 7 for transporting soil to the arc transition is installed on the sieve shaking frame 4, and a plurality of layers of sieve rollers 51 are rotatably connected to the swing plate 5, and each layer of sieve rollers 51 is arranged obliquely, and the diameter of the sieve rollers decreases from top to bottom, and a spring 52 is connected between the bottom of the swing plate 5 and the two side walls of the sieve shaking frame 4. When the soil is rolled to the arc transition by the rolling member 7, it then falls back to the surface of the multi-layer sieve rollers 51; a stone receiving bag 8 is installed on the tillage frame 1, and the front end of the stone receiving bag 8 is arc-shaped, and the rear end of the stone receiving bag 8 is a flat plate, and the two side walls of the stone receiving bag 8 are connected to the tillage frame 1. The tiller frame 1 is rotatably connected, and the bottom of the stone collecting bag is located at the front end of the lowest screen roller 51; because each layer of screen rollers 51 is arranged obliquely, and the diameter of the screen rollers 51 decreases from top to bottom, large stones are passed through the top layer of screen rollers, and the diameter of the screen rollers 51 can be selected according to the user's own choice. The smaller the diameter of the screen rollers 51 and the denser the distribution, the smaller the stones screened by the screen rollers 51 of this layer. Screening the stones and soil with the screen rollers 51 is convenient for peeling off the stones and soil on the one hand, and is beneficial for multi-layer screening of the soil on the other hand, so that the stones are fully screened out from the soil, and the stones slide along the screen rollers 51 into the stone collecting bag 8.

[0027] When the stone reaches a certain weight in the stone receiving pocket 8, it is necessary to take the stone out of the stone receiving pocket 8, and a pulling assembly 6 for pulling the swing plate 5 and reversing the stone receiving pocket 8 is installed on the outer wall of the tilling frame 1.

[0028] For the process of turning the soil from the curved tillage blade 3 to the sifting frame 4 and transporting it on the sifting frame 4, refer to Figure 1 , Figure 3 and Figure 6 It can be seen that the rolling element 7 includes a plurality of propulsion rollers 71 mounted on the sieve frame 4, and the outer walls of the propulsion rollers 71 are tangent to each other, the tops of the propulsion rollers 71 are connected by a transmission belt 72, and one end of the transmission belt 72 is connected to a drive motor 73, and the drive motor 73 is mounted on the outer wall of the tilling frame 1. When the soil falls on the propulsion roller 71 in a parabolic shape, the roller surface of the propulsion roller 73 is slightly higher than the inclined plane of the sieve frame 4, so that the soil falls on the propulsion roller first, and even if the soil does not fall on the propulsion roller 73, it will slide to the bottom position. Afterwards, the soil can be pushed back into the pushing roller 73 by the front end of the bottom of the screening frame 4. Since the outer walls of the pushing rollers 73 are tangent to each other, multiple pushing rollers 73 form a complete surface. Of course, when the pushing rollers 73 are driven by the driving motor 73 through multiple transmission belts 72, the soil is easily crushed and leaks out from the rolling gap of the pushing rollers 73. The pushing rollers here are rollers with threaded surfaces. Conveyor belts can also be arranged through the screening frame 4 to transport the turned over soil to the arc-shaped transition position at the top of the screening frame 4.

[0029] For how to pour out the 8 stones from the stone collecting bag, refer to the attached Figure 2 It can be seen that the pulling assembly 6 includes a first guide roller 61 and a winding rope 62 installed at the front end position of the tilling frame 1, a winding roller 63 is installed at the rear end position of the tilling frame 1, a second guide roller 64 is installed on the bottom side wall of the swing plate 5, a splicing block 65 is installed on the bottom side wall of the stone pocket 8, and a splicing groove 66 is provided on the splicing block 65, and the upper inner wall of the splicing groove 66 is an arc transition, the winding rope 62 passes through the second guide roller 64, the first guide roller 61, the splicing groove and the winding roller 63 in sequence, and the winding roller 63 is driven by power to wind the winding rope 62, and the winding rope 62 is bonded with a splicing plug 67 at the position of the first guide roller 61 and the splicing groove 66, and the splicing plug 67 can be engaged in the splicing groove 66.

[0030] When the weight of the stones inside the stone receiving bag 8 is large enough, the driving device is started at this time. The driving device here can be a motor, a manual shake, or other equipment that can make the winding roller 63 rotate. Under the power of the driving device, the winding rope 62 contracts at this time. Through the contraction of the winding rope 62, the swing plate 5 is first pulled to turn toward the tilling roller 2. At this time, the multi-layer screen rollers 51 installed on the swing plate 5 turn at the same time. On the one hand, it is convenient to quickly shake the stones into the stone receiving bag 8. On the other hand, it is beneficial for the screen rollers 51 to leave avoidance space for the stone receiving bag 8. When the splicing plug 67 of the winding roller 63 is pulled into the splicing groove 66, the splicing block 65 will jam the winding rope 63. When winding again, the winding rope 62 will pull the stone receiving bag 8 to turn along the rotating shaft position, thereby causing the stones in the stone receiving bag 8 to dump.
