Description

Technical Field

[0001] This utility model relates to a five-toothed rake, and more specifically, to an adjustable-angle, non-slip, and labor-saving five-toothed rake. Background Technology

[0002] Five-pronged rakes are commonly used agricultural and horticultural tools for loosening and breaking up soil. However, existing products have significant shortcomings: The fixed angle of the prongs makes them unsuitable for different soil types, working depths, and operator postures, resulting in a suboptimal angle of penetration and high cutting resistance, requiring extra effort to insert. In sandy soil, they may even penetrate too deeply, increasing ineffective resistance. The handles are often made of smooth materials or only have simple anti-slip features, making them prone to slippage due to sweaty hands and uneven force distribution during operation. This prevents the force from being effectively transmitted to the prongs, requiring extra effort to maintain a grip and increasing labor load. These limitations fail to meet the demands for efficient operation and necessitate urgent technological improvements. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the present invention provides an adjustable-angle, anti-slip, and labor-saving five-tooth rake, the beneficial effect of which is that the sharp teeth are inserted into the soil in a labor-saving manner.

[0004] An adjustable-angle, non-slip, and labor-saving five-tooth rake includes a tooth base on which five sharp teeth are fixed. The ends of the sharp teeth are provided with pointed tips, and one side of each sharp tooth is provided with a triangular blade.

[0005] The gear seat is equipped with an adjustable handle.

[0006] A rubber tube is glued to the handle.

[0007] The rubber cylinder has multiple annular grooves evenly distributed on it.

[0008] A rotating seat is fixed on the handle, a rotating shaft is fixed on the rotating seat, and a shaft seat is fixed on the gear seat. The rotating shaft is rotatably connected to the shaft seat.

[0009] Two limiting rings are fixed on the rotating shaft, and the two limiting rings are respectively attached to the outer side of the two shaft seats.

[0010] A prism is fixed on the rotating shaft.

[0011] The toothed seat is provided with a right-angled member, and the right-angled member is provided with a hole corresponding to the prism, and the prism is inserted into the hole.

[0012] The right-angled piece is provided with screw holes, and the screw is inserted into the screw holes. The lower end of the screw is connected to the toothed seat by a thread.

[0013] The screw presses the right-angled piece firmly onto the toothed seat. Attached Figure Description

[0019] An adjustable-angle, non-slip, and labor-saving five-tooth rake includes a tooth base 1, on which five sharp teeth 2 are fixed. The ends of the sharp teeth 2 are provided with pointed tips 3, and one side of the sharp teeth 2 is provided with a triangular blade 14.

[0020] like Figure 1-3 As shown;

[0021] The pointed tip 3 at the end of the pointed tooth 2 reduces the contact area with the soil and lowers the initial cutting resistance; the triangular blade 14 on one side of the pointed tooth 2 can cut and separate the soil to both sides when it enters the soil, reducing the soil's squeezing resistance on the pointed tooth. Together with the pointed tip 3, it achieves a dual labor-saving effect of "cutting + piercing", making it easier for the pointed tooth to be inserted into the soil.

[0022] The gear seat 1 is provided with an adjustable handle 11.

[0023] like Figure 1-3 As shown;

[0024] The angle of the handle 11 is adjustable. Users can flexibly adjust the relative angle between the handle 11 and the toothed seat 1 according to the soil texture, working depth and their own operating posture, so as to minimize cutting resistance and avoid extra effort.

[0025] A rubber tube 10 is attached to the handle 11.

[0026] like Figure 1-3 As shown;

[0027] The rubber cylinder 10 bonded to the handle 11 utilizes the high frictional properties of rubber to increase the contact friction between the hand and the handle 11, effectively preventing slippage caused by sweaty hands or uneven force during operation, ensuring that the force applied by the user can be efficiently transmitted to the tooth 2, and avoiding the waste of energy due to slippage.

[0028] The rubber cylinder 10 has multiple annular grooves 9 evenly distributed on it.

[0029] like Figure 1-3 As shown;

[0030] Multiple annular grooves 9 evenly distributed on the rubber cylinder 10 further increase the contact texture between the hand and the rubber cylinder 10, improving the anti-slip effect; at the same time, the annular grooves 9 can accommodate hand sweat, reduce the risk of slipping caused by sweat, make the grip more stable, and transmit force more directly, indirectly reducing the workload.

[0031] A rotating seat 12 is fixed on the handle 11, a rotating shaft 7 is fixed on the rotating seat 12, and a shaft seat 13 is fixed on the gear seat 1. The rotating shaft 7 is rotatably connected to the shaft seat 13.

[0032] like Figure 1-3 As shown;

[0033] The handle 11 is fixed to the rotating shaft 7 by the rotating seat 12. The rotating shaft 7 is rotatably connected to the bearing seat 13 on the gear seat 1, forming the core rotating structure for angle adjustment. Users can rotate the handle 11 to drive the rotating shaft 7 to rotate within the bearing seat 13, thereby adjusting the angle between the handle 11 and the gear seat 1 to suit different operating needs.

[0034] Two limiting rings 8 are fixed on the rotating shaft 7, and the two limiting rings 8 are respectively attached to the outer side of the two shaft seats 13.

[0035] like Figure 1-3 As shown;

[0036] The two limiting rings 8 on the rotating shaft 7 are respectively attached to the outer side of the two bearing seats 13 to limit and fix the axial position of the rotating shaft 7, prevent the rotating shaft 7 from moving axially during angle adjustment or operation, ensure the stability after angle adjustment, and avoid affecting the consistency of the force on the pointed teeth entering the soil due to movement.

[0037] A prism 6 is fixed on the rotating shaft 7.

[0038] like Figure 1-3 As shown;

[0039] The prism 6 fixed on the pivot 7 provides rigid support for angle positioning. The polygonal structure of the prism enables the subsequent right-angle piece 4 to be precisely engaged and positioned, avoiding slippage and deflection after angle adjustment, and ensuring that the adjusted soil insertion angle remains stable.

[0040] The tooth base 1 is provided with a right-angle member 4, and the right-angle member 4 is provided with a hole corresponding to the prism 6, and the prism 6 is inserted into the hole.

[0041] like Figure 1-3 As shown;

[0042] The hole on the right-angle piece 4 corresponds to the prism 6. When the angle is adjusted to the target position, the hole of the right-angle piece 4 is inserted into the prism 6. The angle is positioned by the fit between the shape of the prism 6 and the hole, which restricts the rotation of the shaft 7 from continuing to rotate and ensures that the soil entry angle of the tooth 2 does not deviate during operation.

[0043] The right-angled member 4 is provided with screw holes, and the screw 5 is inserted into the screw holes. The lower end of the screw 5 is connected to the toothed seat 1 by a thread.

[0044] like Figure 1-3 As shown;

[0045] Screw 5 is inserted into the screw hole of right-angle piece 4 and threadedly connected to tooth base 1. The right-angle piece 4 and tooth base 1 are fixed by the thread tightening force, which indirectly locks the position of prism 6 and achieves fixation after angle adjustment. Users can adjust the angle by loosening screw 5 and tighten screw 5 to complete the fixation, which is convenient to operate.

[0046] The screw 5 presses the right-angle piece 4 tightly onto the toothed seat 1.

[0047] like Figure 1-3 As shown;

[0048] Screw 5 presses the right-angle piece 4 tightly onto the toothed seat 1, increasing the contact pressure between the right-angle piece 4 and the toothed seat 1 and the prism 6, further enhancing the firmness of the angle locking, and ensuring that the right-angle piece 4 will not loosen during operation.
