Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and particularly relates to a crop flattening machine. Background Art

[0002] Returning straw to the field is a method of agricultural resource utilization. After harvesting the crops, the straw is left in the field instead of being burned or discarded, but returned to the field as organic fertilizer. Returning straw to the field can increase soil organic matter, improve soil structure, make the soil loose, increase porosity, reduce bulk density, and promote the activity of microorganisms and the development of crop roots. In the case of returning straw to the field, rolling is particularly important because the mixing of straw and soil makes the soil lose its granularity and become loose, reducing the impact on the seeding and growth of subsequent crops and being beneficial to improving the growth environment of crops.

[0003] Currently, in the prior art, a lawn roller is often used for rolling in straw returning to the field. Although the lawn roller has a simple structure, is convenient to use and has a low cost, since it uses an ordinary roller which only flattens and does not have the function of cutting crops, the mixing of straw and soil is not sufficient. In addition, since the lawn roller needs to be manually pulled, the labor intensity is high and the working efficiency is not high enough. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a crop flattening machine which can be installed on a traction power device, and the connecting frame is pulled forward by the traction power device to drive the roller to roll, and the crops are flattened and cut by the bending blades.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The crop flattening machine includes a roller and a connecting frame; both ends of the roller are rotatably connected to one side of the connecting frame, and a plurality of bending blades arranged along the circumferential direction of the roller are provided on the outer peripheral surface of the roller, and the bending blades are bent towards the rotation direction of the roller; the other side of the connecting frame is used for being installed on a traction power device, and the connecting frame is pulled forward by the traction power device to drive the roller to roll forward, so as to flatten and cut the crops through the bending blades.

[0007] As an optional scheme, a water injection pipe communicating the inside and outside of the roller is provided on the roller, and a pipe plug for opening and closing the water injection pipe is provided in the water injection pipe.

[0008] As an optional scheme, the connecting frame includes a triangular frame body and a cross plate; the triangular frame body is used for being fixedly connected to the rear three-point suspension of a tractor, and the two cross plates are respectively fixedly connected to the two bottom corners of the triangular frame body, and both ends of the roller are respectively rotatably arranged at one ends of the two cross plates far away from the triangular frame body.

[0009] As an alternative solution, square-seated bearings are rotatably connected to both ends of the drum, and the two square-seated bearings are respectively installed at one end of the two cross plates away from the triangular frame body; an inner protective cover and an outer protective cover that can be spliced with each other are sleeved outside the square-seated bearings.

[0010] As an alternative solution, an upper mounting plate is fixedly connected to the top angle of the triangular frame body, and lower mounting plates are respectively fixedly connected to both sides of the bottom edge of the triangular frame body. Two upper pins penetrate through the upper mounting plate, and a heavy pin is clamped at one end of one of the upper pins, and a B-type pin is clamped at one end of the other upper pin for fixing the upper mounting plate; a lower through pin penetrates through the lower mounting plate, and a heavy pin is clamped at one end of the lower through pin to fix the lower mounting plate.

[0011] As an alternative solution, fixing frames are respectively fixedly connected to both sides of the bottom of the connecting frame, a support pipe is inserted into the fixing frames, and the lower end of the support pipe extends out of the fixing frames to support the connecting frame; a pin assembly penetrates through the fixing frames, and a plurality of limiting holes are formed in the support pipe in the height direction. The height of the lower end of the support pipe extending out of the fixing frames is adjusted by fixedly inserting the pin assembly into different limiting holes.

[0012] As an alternative solution, a plurality of slices arranged along the length direction of the bent blade are provided on the concave side surface of the bent blade.

[0013] Due to the adoption of the above technical solutions, the present utility model will have the following beneficial effects:

[0014] A crop flattening machine provided by the present utility model, by arranging a drum on one side of the connecting frame and installing the connecting frame on a traction power device, can be pulled forward by the traction power device, thereby driving the drum to roll forward. Compared with the prior art lawn roller machine that requires manual hand pulling operation, the labor intensity can be reduced and the work efficiency can be improved; at the same time, by arranging a plurality of bent blades on the outer peripheral surface of the drum, these bent blades can continuously press down the crops during the rolling of the drum to flatten the crops, and cut the crops under the action of the gravity of the drum. Compared with the prior art lawn roller machine, the straw can be fully mixed with the soil, which is beneficial to the sowing and growth of subsequent crops, thereby improving the growth environment of the crops.

[0015] In addition, by setting the bent blades to bend towards the rotation direction of the drum, the bent parts of the bent blades can separate the crops to both sides during the rolling of the drum, so that the drum can move forward more easily, and compared with falling forward, the crops falling to both sides are not easily stacked together, thereby preventing affecting flattening and cutting.

Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Please refer to Figures 1-4 , in an embodiment of a crop flattening machine of the present utility model, the crop flattening machine includes a roller 1 and a connecting frame 2; wherein, both ends of the roller 1 are rotatably connected to one side of the connecting frame 2, and a plurality of bending blades 11 arranged circumferentially and evenly along the roller 1 are welded on the outer peripheral surface of the roller 1, and the bending blades 11 are bent toward the rotation direction of the roller 1; the other side of the connecting frame 2 is used for installation on a traction power device.

[0026] When this embodiment is in use, the connecting frame 2 is pulled forward by the traction power device to drive the roller 1 to roll forward. While the roller 1 rolls forward to drive the bending blades 11 to move forward, the bending blades 11 make a circular motion, so that the plurality of bending blades 11 continuously press down the crops during the rolling of the roller 1 to flatten the crops, and cut the crops under the action of the gravity of the roller 1.

[0027] Since the connecting frame 2 can be installed on the traction power device and pulled forward by the traction power device, the labor intensity can be reduced and the work efficiency can be improved. Since the bending blades 11 are bent toward the rotation direction of the roller 1, the bent parts of the bending blades 11 can separate the crops to both sides during the rolling of the roller 1, making it easier for the roller 1 to move forward. Moreover, compared with falling forward, the crops falling to both sides are not easily stacked together, thus preventing the influence on flattening and cutting.

[0028] Specifically, two water injection pipes can be fixedly connected to the middle of the outer peripheral surface of the drum 1, and the two water injection pipes are symmetrically distributed with the axis of the drum 1 as the symmetry axis; a pipe plug 12 is threadedly connected inside the water injection pipe. Unscrewing the pipe plug 12 can open the main water pipe, and water can be injected into the drum 1 through the water injection pipe. By using the injected water to increase the weight of the drum 1, compared with a solid drum 1, the cost of the product is reduced; after the drum 1 is filled with water, the water injection pipe is blocked with the pipe plug 12.

[0029] Specifically, the connecting frame 2 can be set to include a triangular frame body 21 and a cross plate 22; the triangular frame is formed by welding three square pipes end to end, and there is also a square pipe inside the triangular frame for strengthening by connecting the vertex and the bottom edge of the triangular frame. This triangular frame is used for fixed connection to the rear three-point hitch of the tractor. The two cross plates 22 are respectively fixedly connected to the two bottom corners of the triangular frame body 21, and both ends of the drum 1 are rotatably arranged at one end of the two cross plates 22 away from the triangular frame body 21.

[0030] More specifically, square seat bearings 3 can be rotatably connected to both ends of the drum 1 respectively. One end of the two cross plates 22 away from the triangular frame body 21 is a hollow structure, and its internal is a receiving cavity that can accommodate the square seat bearings 3. The two square seat bearings 3 are respectively installed in the two receiving cavities through hexagon socket head cap screws 31. A spring washer 32 and a plain washer 33 are sequentially placed under the nut of the hexagon socket head cap screw 31 to improve the fixing effect on the square seat bearings 3. An inner protective cover 41 and an outer protective cover 42 are sleeved outside the square seat bearings 3. The inner protective cover 41 and the outer protective cover 42 are spliced together through the hexagon socket head cap screws 31 to completely cover the square seat bearings 3, preventing sundries such as sediment from entering the square seat bearings 3. The outer protective cover 42 can be made of a transparent material; a spring washer 32 and a plain washer 33 are sequentially placed under the nut of the hexagon socket head cap screw 31 to improve the fixing effect on the inner protective cover 41 and the outer protective cover 42.

[0031] Furthermore, an upper mounting plate 211 is welded to the top angle of the triangular frame body 21, and lower mounting plates 212 are respectively welded to both sides of the bottom edge of the triangular frame body 21. Two upper pins 213 are arranged at intervals up and down through the upper mounting plate 211. One end of the upper pin 213 located below is clamped with a heavy pin 215, and one end of the upper pin 213 located above is clamped with a B-type pin 216. By inserting the two upper pins 213 and inserting the heavy pin 215 and the B-type pin 216 to prevent the two upper pins 213 from coming out, the upper mounting plate 211 is fixedly connected to the upper pull rod of the rear three-point hitch of the tractor; a lower through pin 214 is arranged through the lower mounting plate 212. One end of the lower through pin 214 is fixedly connected with a pull ring 2141 for easy pulling out, and the other end of the lower through pin 214 is clamped with a heavy pin 215. By inserting the lower through pin 214 and inserting the heavy pin 215 to prevent the lower through pin 214 from coming out, the lower mounting plate 212 is fixedly connected to the lower pull rod of the rear three-point hitch of the tractor, so that the triangular frame is fixedly connected to the rear three-point hitch of the tractor.

[0032] On this basis, fixing frames 51 can be respectively welded to both sides of the bottom of the connecting frame 2. A square support tube 52 is inserted into the fixing frame 51. The lower ends of the two support tubes 52 extend out of the fixing frame 51 and are flush with each other. Since the connecting frame 2 of the present utility model does not need to be installed on a tractor when not in use, the two support tubes 52 can play a role in supporting the connecting frame 2 at this time. A pin assembly 521 penetrates through the fixing frame 51. The pin assembly 521 can adopt the combination of the above-mentioned under-penetrating pin 214 and heavy pin 215, and the two can be connected by a connecting wire to prevent loss; a plurality of circular limiting holes 522 are formed in the support tube 52 along the height direction. During use, according to the size of the drum 1, adjust the height of the lower end of the support tube 52 extending out of the fixing frame 51 so that its lower end is flush with the bottom of the drum 1, and then insert the pin assembly 521 through the fixing frame 51 and fixedly plug it into the corresponding limiting hole 522 to fix the support tube 52, thereby improving the overall stability.

[0033] It should be noted that in order to cut the straw more finely, a plurality of slices 111 arranged along the length direction of the bent blade 11 can be welded to the concave side of the bent blade 11.

[0034] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
