[0002] The land preparation harrow is a tool used for soil cultivation in agriculture. Its main purpose is to create good soil conditions for crop growth. Land preparation operations include shallow tillage, stubble removal, plowing, deep loosening, harrowing, etc., aiming to create a good soil tillage layer structure and surface state, coordinate factors such as water, nutrients, air and heat, improve soil fertility, and provide good conditions for sowing and crop growth.

[0003] The existing patent (Announcement No.: CN218125307U) proposes a tillage harrow for land preparation, wherein the clamping structure includes a fixed bracket fixedly connected to the outer surface of a transverse bracket, a clamping bracket is movably provided on the outer surface of one side of the fixed bracket, a protruding column is fixedly connected to the outer surface of the clamping bracket, a rotating shaft is penetrated through the outer surface of the protruding column, a rotating column is fixedly connected to one end of the rotating shaft, and a connecting thread is provided at one end of the rotating shaft. The above technical solution solves the problem that the existing tillage harrow for land preparation cannot be conveniently connected to the connecting head of the tillage vehicle, and the installation and use are inconvenient, which can bring better use effect.

[0004] However, existing tillage rakes for land preparation are prone to tipping over when not in use, causing deformation or damage to the structure and causing safety accidents. Frequent tipping over may cause the rake teeth to bend or break, the supporting structure may be deformed, and the connecting parts may be damaged due to impact. An unstable tillage rake may tip over without anyone noticing, causing injuries to workers or passers-by, especially on farms or in the workplace. Users may also accidentally come into contact with the tipped equipment, increasing safety risks. Therefore, the utility model proposes a tillage rake for land preparation to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a tillage harrow for land preparation.

[0006] In order to achieve the above object, the utility model adopts the following technical scheme: a tillage harrow for land preparation, comprising a support seat, a bottom of which is fixed with rake teeth, an angle adjustment component is arranged on the rake teeth, and a quick release component is arranged on the angle adjustment component;

[0007] The angle adjustment assembly comprises a limit seat, a rotating block is rotatably connected in the limit seat, a limit rod is fixed on the rotating block, a first clamping groove is provided on the limit rod, a first clamping buckle is fixed on the limit seat, a second clamping buckle is fixed on the limit seat, and a limit slot is provided on the limit seat;

[0008] The quick-release assembly comprises a fixing block, a bolt is threadedly connected to the fixing block, and a grip rod is arranged inside the fixing block.

[0009] As a preferred embodiment of a tillage harrow for land preparation, the bottom of the limiting seat is fixed on the supporting seat, the limiting rod is slidably connected in the limiting groove, and the first buckle is clamped in the first clamping groove.

[0010] The beneficial effect of adopting the above-mentioned further scheme is: since the bottom of the limit seat is fixed on the support seat, the angle adjustment component can be connected to the support seat and the rake teeth, and the angle of the rake teeth can be adjusted through the angle adjustment component. Since the limit rod is slidably connected in the limit groove, when the limit rod slides in the limit groove, it has a limiting effect on the movement of the limit rod, thereby controlling the movement angle of the rake teeth. Since the first buckle is clamped in the first buckle, the limit rod can be fixed on the side close to the first buckle to prevent the rotating block from moving.

[0011] As a preferred embodiment of a tillage harrow for land preparation, the fixed block is fixed on the rotating block, and a second slot is provided in the fixed block.

[0012] The beneficial effect of adopting the above further scheme is: since the fixed block is fixed on the rotating block, the quick-release assembly is connected and fixed to the angle adjustment assembly, and since a second slot is provided in the fixed block, the grip can be fixed in the fixed block through the cooperation of the second slot and the block.

[0013] As a preferred embodiment of a tillage harrow for land preparation, a clamping block is fixed on the handle, and the clamping block is clamped in the second clamping groove.

[0014] The beneficial effect of adopting the above further solution is that since a clamping block is fixed on the handle and the clamping block is clamped in the second clamping groove, the handle is prevented from moving when the tillage harrow is in use.

[0015] As a preferred embodiment of a tillage harrow for land preparation, a reinforcement assembly is arranged on the support seat, and the reinforcement assembly includes a support rod, and the support rod is rotatably connected to the handle.

[0016] The beneficial effect of adopting the above further solution is that since the support rod is rotatably connected to the grip rod, the support rod can be selectively clamped in the first clamping seat or the second clamping seat.

[0017] As a preferred embodiment of a tillage harrow for land preparation, a first clamping seat is fixed on the support seat, a second clamping seat is fixed on the handle, and the support rod is clamped in the first clamping seat.

[0018] The beneficial effect of adopting the above further scheme is that through the provision of the first clamping seat, when the support rod is clamped in the first clamping seat, the support rod can reinforce the support seat to prevent the angle adjustment component from being damaged due to excessive force when the arable land is being cultivated.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] When the user is not using the tillage rake, he rotates the support seat to rotate the rake teeth to a position flush with the grip rod. Due to the rotation of the support seat, the limit rod moves along the direction of the limit slot to close to the second buckle, and the second buckle is buckled into the first slot. Through the cooperation of the limit rod and the second buckle, a locking relationship is established between the second buckle and the limit rod, ensuring that the rake teeth remain in a folded state, so that the tillage rake can achieve a folding effect, thereby solving the technical problem that the tillage rake may tip over when not in use, causing the structure to deform or be damaged and causing a safety accident.

[0027] 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.

[0028] like Figure 1-4 As shown, a tillage harrow for land preparation comprises a support base 1, a rake tooth 2 is fixed to the bottom of the support base 1, an angle adjustment component 3 is arranged on the rake tooth 2, and a quick release component 4 is arranged on the angle adjustment component 3;

[0029] The angle adjustment assembly 3 includes a limit seat 31, a rotating block 32 is rotatably connected in the limit seat 31, a limit rod 33 is fixed on the rotating block 32, a first clamping groove 34 is provided on the limit rod 33, a first buckle 35 is fixed on the limit seat 31, a second buckle 36 is fixed on the limit seat 31, and a limit slot 37 is provided on the limit seat 31;

[0030] The quick-release assembly 4 includes a fixing block 41, on which a bolt 42 is threadedly connected, and a grip rod 44 is arranged inside the fixing block 41. When the user does not use the tillage rake, the support seat 1 is rotated to rotate the rake teeth 2 to a position flush with the grip rod 44. Due to the rotation of the support seat 1, the limit rod 33 moves along the direction of the limit groove 37 to a position close to the second buckle 36, and the second buckle 36 is buckled into the first buckle groove 34. Through the cooperation of the limit rod 33 and the second buckle 36, a locking relationship is formed between the second buckle 36 and the limit rod 33, ensuring that the rake teeth 2 remain in a folded state, so that the tillage rake can achieve a folding effect. By adopting this folding mechanism, the tillage rake can be safely stored when not in use, reducing damage and potential safety risks caused by improper storage, thereby solving the technical problem that the tillage rake may tip over when not in use, causing structural deformation or damage and causing safety accidents.

[0031] The above schemes still have the problem that when the tillage harrow is working on the land, it cannot meet the strength of the land and the tillage harrow breaks. Figure 1-4 As shown: the bottom of the limit seat 31 is fixed on the support seat 1, the limit rod 33 is slidably connected in the limit groove 37, and the first buckle 35 is clamped in the first clamping groove 34. By setting the limit seat 31 and fixing its bottom on the support seat 1, the angle adjustment component 3 becomes an important intermediate component connecting the support seat 1 and the rake teeth 2, so that the rake teeth 2 can be accurately adjusted in angle to adapt to different farming requirements and ground conditions. The limit rod 33 can slide freely in the limit groove 37 and is restricted by the shape of the limit groove 37. This ensures the flexibility of adjustment and ensures that the rake teeth 2 will not exceed the predetermined adjustment range. The cooperation between the first buckle 35 and the first clamping groove 34 is a part of the locking mechanism, which ensures that the limit rod 33 can be firmly fixed in the predetermined position after the angle adjustment is completed.

[0032] like Figure 1-3As shown, the fixed block 41 is fixed on the rotating block 32, and a second slot 43 is provided in the fixed block 41. Since the fixed block 41 is fixed on the rotating block 32, the quick-release assembly 4 is connected and fixed to the angle adjustment assembly 3. Since the second slot 43 is provided in the fixed block 41, the grip 44 can be limited and fixed in the fixed block 41 through the cooperation of the set second slot 43 and the block 45, which is convenient for users to quickly disassemble and replace parts. For example, when the grip 44 is damaged or needs to be replaced, the user can simply complete the disassembly and installation work quickly through the quick-release assembly 4 without using special tools, thereby reducing maintenance time and improving work efficiency. A block 45 is fixed on the grip 44, and the block 45 is clamped in the second slot 43. The stability is directly related to the performance of the tillage rake and the labor intensity of the operator. By fixing the block 45 on the grip 44 and snapping it into the second slot 43, this structural design limits the movement of the grip 44 and improves stability during use. A reinforcement component 5 is provided on the support seat 1, and the reinforcement component 5 includes a support rod 51, which is rotatably connected to the grip 44. Since the support rod 51 is rotatably connected to the grip 44, the support rod 51 can be selectively snapped into the first snap seat 52 or the second snap seat 53. The support seat 1 is fixed with a first snap seat 52, and the grip 44 is fixed with a second snap seat 53. The support rod 51 is snapped into the first snap seat 52. Through the provision of the first snap seat 52, when the support rod 51 is snapped into the first snap seat 52, the support rod 51 can reinforce the support seat 1 to prevent the angle adjustment component 3 from being damaged due to excessive force when the raking is used to cultivate the land.

[0033] Working principle:

[0034] like Figure 1-4As shown, first, when the user does not use the tillage rake, he rotates the support seat 1 and rotates the rake teeth 2 to a position flush with the grip 44. Due to the rotation of the support seat 1, the limit rod 33 moves along the direction of the limit slot 37 to a position close to the second buckle 36, and the second buckle 36 is buckled into the first buckle 34. Through the cooperation of the limit rod 33 and the second buckle 36, a locking relationship is formed between the second buckle 36 and the limit rod 33, ensuring that the rake teeth 2 remain in a folded state, thereby achieving a folding effect of the tillage rake. By adopting this folding mechanism, the tillage rake can be safely stored when not in use, reducing damage and potential safety risks caused by improper storage. When the tillage rake is needed to be used for tilling the land, the support seat 1 is rotated. The support base 1 rotates the rake teeth 2 to a position perpendicular to the grip rod 44, and the first buckle 35 is engaged in the first slot 34, so that the rake teeth 2 are perpendicular to the grip rod 44. Through the provided first socket 52, when the support rod 51 is engaged in the first socket 52, the support rod 51 can reinforce the support base 1 to prevent the angle adjustment component 3 from being damaged due to excessive force when the raking is in the field. Through the provided quick-release component 4, the grip rod 44 can be removed from the fixed block 41 by screwing the bolt 42. For example, when the grip rod 44 is damaged or needs to be replaced, the user can simply use the quick-release component 4 to quickly complete the disassembly and installation work without using special tools, thereby reducing maintenance time and improving work efficiency.
