Detailed Implementation

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figures 1-5 As shown, the multi-tooth flat rake includes a mounting plate 1 and a side support frame 2. Multiple crossbars 3 and 4 are fixedly connected below the mounting plate 1 and the side support frame 2. Multiple rake teeth 5 are fixedly connected below the crossbars 3 and 4 respectively. The multiple rake teeth 5 below the crossbars 3 and 4 are arranged in an alternating manner.

[0031] The preferred spacing between the rake teeth 5 is 5cm. This makes the distance between the staggered rake teeth 5 between the crossbar 1 3 and the crossbar 2 4 2.5cm. At the same time, the distance between the crossbar 1 3 and the crossbar 2 4 is 5cm. This allows the multiple rows of crossbar 1 3 and crossbar 2 4 to form a stable plane, which can more quickly crush large soil clods and quickly level the ground when rakeing.

[0032] The preferred angle between the rake teeth 5 and the horizontal plane is 60 degrees, which allows for better insertion into the leveled land.

[0033] In the embodiment, the mounting sleeve 6 is fixedly connected above the mounting plate 1, the support rod 7 is fixedly connected below the mounting sleeve 6 and above the mounting plate 1, and the mounting sleeve 6 is provided with a nail hole 8 on one side.

[0034] The mounting sleeve 6 can be inserted into a wooden rod and fixed by inserting a nail through the nail hole 8, and the support rod 7 can improve the stability of the mounting sleeve 6.

[0035] In the embodiment, the distance between the tines 5 is 5 cm, so the distance between the staggered tines 5 between the horizontal rod one 3 and the horizontal rod two 4 is 2.5 cm, and the distance between the horizontal rod one 3 and the horizontal rod two 4 is 5 cm, so that the multiple rows of horizontal rod one 3 and horizontal rod two 4 can form a stable plane, which can more quickly crush large soil blocks and quickly level the ground.

[0036] Preferably, the angle between the tine 5 and the horizontal plane is 60 degrees, which can better insert into the land and level the ground, the mounting sleeve 6 can be inserted into a wooden rod and fixed by inserting a nail through the nail hole 8, and the support rod 7 can improve the stability of the mounting sleeve 6.

[0037] Embodiment 2:

[0038] Multi-tooth land leveler, the embodiment is improved on the basis of embodiment 1, as shown in Figures 1-5

[0039] In the embodiment, the connection mode of the horizontal rod one 3 and the horizontal rod two 4 with the mounting plate 1 and the side support frame 2 is replaced from fixed connection to rotary connection, and the horizontal rod one 3 and the horizontal rod two 4 are respectively provided with a plurality of positioning grooves 17 on one side; in use, the angle of the tine 5 can be adjusted by rotating the horizontal rod one 3 and the horizontal rod two 4, so that it can be used for different soil and work requirements.

[0040] The side support frame 2 is fixedly connected with a slide rod 15 above, and the side support frame 2 is threadedly connected with a positioning bolt 14 above, the positioning bolt 14 is threadedly connected with a lifting pressing plate 13 below, the two slide rods 15 are slidingly connected in the lifting pressing plate 13, and the lifting pressing plate 13 is fixedly connected with a plurality of positioning teeth 16 below, and the positioning teeth 16 can be inserted into the positioning grooves 17.

[0041] Rotating the positioning bolt 14 can quickly move the lifting pressing plate 13, the positioning teeth 16 are inserted into the corresponding positioning grooves 17, the angles of all horizontal rod one 3 and horizontal rod two 4 can be quickly determined at the same time, and the operation is more convenient.

[0042] ​In this embodiment, limit grooves 19 are respectively opened on both sides of the first crossbar 3 and the second crossbar 4. A telescopic sleeve 11 is slidably connected to one side of the side support frame 2. A side fixing plate 12 is fixedly connected to one side of the telescopic sleeve 11. Multiple limit bosses 18 are fixedly connected to the inner side of the side fixing plate 12. The limit bosses 18 can be inserted into the limit grooves 19. A double-ended screw 9 is rotatably connected to one side of the mounting plate 1. The two sides of the double-ended screw 9 are threaded to the telescopic sleeve 11. An adjusting nut 10 is fixedly connected to one side of the double-ended screw 9.

[0043] The double-headed screw 9 can be rotated by adjusting the nut 10, which will drive the telescopic sleeves 11 on both sides to move inward and outward at the same time. In this way, the octagonal limiting boss 18 can be inserted into the corresponding limiting groove 19 to achieve simultaneous limiting of the angles of all the crossbars 1 3 and 2 4 on both sides. Moreover, the multiple limiting bosses 18 fix it from both sides to make it more stable, which can effectively prevent shaking and falling off due to impact.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
