Description

Technical Field

[0001] This application relates to the field of agricultural equipment technology, specifically to an anti-grass tangling structure and an adjustable rotary tillage device. Background Technology

[0002] Tillage equipment is widely used in the agricultural field. There are many forms of existing tillage equipment, but they generally include a frame, a push device connected to the frame, a rotary planer mounted on the frame, and a power device that is connected to the rotary shaft of the rotary planer. The rotary planer includes a rotary shaft that is parallel to the ground and has blades on it. When tilling, the rotary shaft rotates and drives the blades to dig and turn the soil downwards to loosen it.

[0003] When existing rotary tillage devices are used to till the ground, weeds are easily entangled on the tillage blades. This can lead to excessive soil accumulation and entanglement due to the entangled weeds, thus affecting the tillage effect. Therefore, this application proposes an anti-entanglement structure and an adjustable rotary tillage device. Utility Model Content

[0004] The purpose of this application is to provide an anti-grass entanglement structure and an adjustable rotary tillage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] One of the objectives of this application is to provide an anti-tangle grass structure, comprising:

[0007] The machine casing has a rotary tiller shaft that rotates through it. Several cutter discs are arranged in an array on the rotary tiller shaft, and two tiller blades are symmetrically arranged on each cutter disc.

[0008] A mounting plate is set on the inner wall of one side of the housing. Several cutting blades are arranged in an array on the mounting plate, and the cutting blades are distributed alternately with several cutter discs.

[0009] Furthermore, the tiller includes a handle, which is fixed to the blade disc by the cooperation of a first bolt and a first nut. The handle is provided with a long blade and a short blade, both of which are curved.

[0010] Furthermore, the cutter head is provided with a insertion slot, and the cutter shank is inserted into the insertion slot.

[0011] Furthermore, the cutter is curved and its end is positioned within the gap between two adjacent tillage blades.

[0012] Furthermore, a connecting block is provided on the mounting plate, and the cutter is fixed to the connecting block by the cooperation of a second bolt and a second nut.

[0013] Furthermore, the cutter head is coaxially connected to an installation cylinder, which is sleeved on the rotary tiller shaft and fixed by the engagement of screws and screw holes.

[0014] Furthermore, the rotary tillage shaft is provided with an external spline, and the mounting cylinder is provided with an internal spline that engages with the external spline.

[0015] The second objective of this application is to propose an adjustable rotary tillage device, including the aforementioned anti-weed tangling structure, and also including a mounting frame. The mounting frame is provided with two vertical rods, and the machine housing is provided with a connecting plate that is slidably sleeved on the two vertical rods. A hydraulic cylinder is connected between the mounting frame and the connecting plate.

[0016] The beneficial effects of this application are as follows: In this application, an installation plate is provided inside the machine casing, and several cutters are provided on the installation plate, with the cutters and tillers distributed alternately. When the rotary tiller rotates and drives the tillers to till the land, the weeds carried by the tillers will be cut and broken by the cutters. This ensures that the weeds will not get tangled on the tillers and rotary tiller, ensuring the tilling effect. At the same time, the cut and broken weeds will be spread in the loosened soil to increase the fertility of the soil. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown, one embodiment of this application proposes an anti-tangle grass structure, comprising:

[0025] The machine casing 1 has a rotary tiller 2 that rotates through it. Several cutter discs 3 are arranged in an array on the rotary tiller 2. Two tiller blades 4 are symmetrically arranged on the cutter discs 3. The machine casing 1 is installed on agricultural machinery or other pushing equipment. The rotary tiller 2 is driven to rotate by a drive device. When the rotary tiller 2 rotates, the tiller blades 4 rotate and dig downwards to the ground plane to loosen the soil.

[0026] Mounting plate 5 is located on one inner wall of the casing 1. A plurality of cutters 6 are arranged in an array on mounting plate 5, with each cutter 6 interleaved with a plurality of cutter discs 3. By installing mounting plate 5 inside the casing 1 and arranging the cutters 6 on it, when the tiller 4 rotary tills and turns the ground, the tiller 4 will carry weeds. Because the cutters 6 are interleaved with the cutter discs 3, when the tiller 4 carries weeds, the weeds will also be carried along with the rotary tiller shaft 2 as the rotary tiller rotates. As the rotary tiller 2 rotates, the weeds are thrown by the rotation of the rotary tiller 2 and pushed by the tiller blades 4. The weeds will spin towards the contact cutter 6 and hit the blade of the cutter 6. The cutter 6 cuts the weeds, which can ensure that the weeds will not get tangled on the tiller blades 4 and the rotary tiller 2, thus ensuring the tillage effect. At the same time, the cutter 6 cuts the impurities. The array of cutter blades 6, under the action of the array of tiller blades 4, can cut and crush the weeds. The cut and crushed weeds will be spread in the loosened soil to increase the fertility of the soil.

[0027] In this design, an installation plate 5 is installed inside the casing 1. Several cutters 6 are installed on the installation plate 5, and the cutters 6 and tillers 4 are staggered. When the rotary tiller 2 rotates and drives the tillers 4 to till the land, the weeds caught in the tillage will be cut and broken by the cutters 6. This ensures that the weeds will not get tangled on the tillers 4 and the rotary tiller 2, thus ensuring the tillage effect. At the same time, the cut and broken weeds will be spread in the loosened soil to increase the fertility of the soil.

[0028] like Figure 5 As shown, in some embodiments, the tiller 4 includes a handle 401, which is fixed to the blade disc 3 by the cooperation of a first bolt 7 and a first nut 8. The handle 401 is provided with a long blade 402 and a short blade 403, both of which are curved. The tiller 4 has a long blade 402 and a short blade 403, which are curved and of different lengths, making the tiller 4 have a double edge. When tilling the land, the short blade 403 and the long blade 402 alternately throw soil, resulting in better soil breaking performance. After long-term use, the tiller 4 will wear down. The handle 401 is fixed to the blade disc 3 by the cooperation of the first bolt 7 and the first nut 8, making the tiller 4 and the blade disc 3 detachably connected, which facilitates the disassembly of the tiller 4 for maintenance and replacement.

[0029] like Figure 5 As shown, in some embodiments, the cutter head 3 is provided with a insertion groove 9, and the handle 401 is inserted into the insertion groove 9. When installing the tiller 4, the handle 401 is first inserted into the insertion groove 9 of the cutter head 3, and then fixed by the cooperation of the first bolt 7 and the first nut 8. The insertion groove 9 is used to enhance the connection strength between the tiller 4 and the cutter head 3, so that when tilling the land, the cutter head 3 can bear part of the stress with the help of the insertion groove 9, so as to share the stress borne by the first bolt 7, thereby improving practicality.

[0030] like Figure 3 As shown, in some embodiments, the cutter 6 has an arc and its end is placed in the gap between two adjacent tillers 4. The cutter 6 has an arc and its end is placed between two tillers 4. Combined with the arc of the tillers 4, the tangential area between the cutter 6 and the tillers 4 is large. When the rotary tiller 2 drives the tillers 4 to rotate, the cutting effect on weeds is better, and the anti-tangling effect is further improved.

[0031] like Figure 3 As shown, in some embodiments, a connecting block 10 is provided on the mounting plate 5, and the cutter 6 is fixed to the connecting block 10 by the cooperation of the second bolt 11 and the second nut 12. Preferably, the connecting block 10 is constructed with a groove, and the handle of the cutter 6 is inserted into the groove. The cutter 6 needs to cut weeds, and its blade needs to be sharp. After long-term use, its blade will become dull due to some influence. By setting the connecting block 10 and fixing it by the cooperation of the second bolt 11 and the second nut 12, the cutter 6 and the mounting plate 5 are detachably connected, which makes it easy to disassemble the cutter 6 for sharpening the blade to ensure the cutting effect on weeds.

[0032] like Figure 4 As shown, in some embodiments, the cutter head 3 is coaxially connected to a mounting cylinder 13. The mounting cylinder 13 is sleeved on the rotary tiller shaft 2 and fixed by the cooperation of screws 14 and screw holes 15. By setting the mounting cylinder 13 on the cutter head 3, the mounting cylinder 13 is sleeved on the rotary tiller shaft 2, and then fixed by the cooperation of screws 14 and screw holes 15, the cutter head 3 and the rotary tiller shaft 2 can be detachably connected, making it easy to disassemble for replacement or maintenance, thereby improving practicality.

[0033] like Figure 4 As shown, in some embodiments, the rotary tiller 2 is provided with an external spline 16, and the mounting cylinder 13 is provided with an internal spline 17 that is connected to the external spline 16. The external spline 16 and the internal spline 17 facilitate the alignment of the rotary tiller 2 and the mounting cylinder 13, and facilitate the installation of the screw 14. At the same time, the connection between the external spline 16 and the internal spline 17 can enhance the connection strength between the mounting cylinder 13 and the rotary tiller 2 and improve the rotational bearing strength of the cutter head 3.

[0034] like Figure 2As shown, an adjustable rotary tillage device proposed in one embodiment of this application includes the aforementioned anti-weed tangling structure and a mounting frame 18. The mounting frame 18 is used to fix itself on an agricultural vehicle. Two vertical rods 19 are provided on the mounting frame 18. A connecting plate 20 is provided on the housing 1 and is slidably sleeved on the two vertical rods 19. A hydraulic cylinder 21 is connected between the mounting frame 18 and the connecting plate 20. Through the sliding cooperation between the connecting plate 20 and the vertical rods 19, the housing 1 can be raised and lowered. When the hydraulic cylinder 21 performs work, its piston end contracts or extends, which can drive the housing 1 to rise and fall, adjusting the tillage depth, thereby adapting to different tillage depth requirements.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
