Description

Technical Field

[0001] The invention relates to an agricultural production tool, in particular to a novel artificial fine land preparation harrow. Background Art

[0002] In agricultural production, whether it is tying seedlings or sowing crops in ridges, fine land preparation is required in advance to ensure the uniformity of sowing and the emergence rate. In addition to turning the soil, traditional seedbed or ridge land preparation requires the topsoil to be repeatedly raked and beaten with a rake to make the topsoil fine and flat in order to ensure the quality of sowing. However, even if the traditional rake is repeatedly raked and beaten, it is actually difficult to make the topsoil very fine, and it is time-consuming and labor-intensive. It is not worth using machinery for seedbeds or ridges with small areas. Therefore, it is still necessary to design a simple and practical new type of manual fine land preparation rake in production practice. Summary of the invention

[0003] Based on the above reasons, the present invention aims to design a simple and practical new type of manual fine soil leveling tool, and the technical measures taken are: a new type of manual fine soil leveling rake, mainly composed of a handle, a rake head frame, a thorn tube, and a rib cover, characterized in that: the rake head frame is in a right-angled U-shape, and corresponding rake head frame shaft holes are provided at the front ends of its two wings, and corresponding rake head frame locking holes are provided at the rear ends. A conical handle tube that forms a certain elevation angle with its overall surface is fixed at the outer center of the middle section of the rake head frame, and a cylindrical handle with a conical front end is fixed therein; the thorn tube is a cylinder with a certain diameter and a length matching the two wings of the rake head frame, and a plurality of rake teeth of a certain length are evenly and neatly fixed on the surface, and a through shaft is provided at the radial center of the cylinder, which is connected in series to the two wings of the rake head frame. The front end is provided with a rake head frame axis hole; the rib cover is on a rectangular frame composed of an opposite side whose length exceeds the diameter of the thorn tube and is perpendicular to the thorn tube and another opposite side whose length matches the outer width of the two wings of the rake head frame and is parallel to the thorn tube. A corresponding rib cover axis hole is provided in the middle of the opposite side perpendicular to the thorn tube, and a corresponding rib cover locking hole is provided at one end. The rib cover axis hole is connected in series through the through axis provided at the radial center of the thorn tube and the rake head frame axis hole provided at the front ends of the two wings of the rake head frame. The rib cover locking hole is fixed to the rake head frame locking hole provided at the rear ends of the two wings of the rake head frame through bolts. On the opposite side parallel to the thorn tube, in the opposite direction to the conical handle tube with a certain elevation angle, and evenly staggered with the rake teeth neatly arranged on the thorn tube, a plurality of arc-shaped ribs with arc bottoms close to the cylinder in the thorn tube are fixed in the same direction.

[0004] The design principle of the present invention is: when the present invention is used, the curved side of the new artificial fine land leveling rake rib cover is placed on the land, and the operation can be carried out in a push-pull manner. The rake teeth on the thorn tube are inserted into the soil and reciprocate to drive the rotation of the thorn tube, and the rake teeth will drive the soil to be turned. No matter it is pushed or pulled, the rake teeth will produce a shearing effect with the adjacent rib covers on both sides during the rotation process, thereby achieving the purpose of breaking the turned soil and realizing the effect of fine land leveling, and the practicality is very strong.

[0005] Since the invention has a simple structure, outstanding effects and low cost, it will have a broad market space. BRIEF DESCRIPTION OF THE DRAWINGS

However, these exemplary embodiments can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art, and in the accompanying drawings, for clarity, the thickness of the layers and regions is expanded, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0012] It should be noted that the following detailed description is illustrative and is intended to provide further explanation to the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those of ordinary skill in the art to which the present application belongs. For ease of description, spatial relative terms, such as "right angle U-shaped overall face", "on ... outside", "right angle U-shaped overall face", etc., can be used here to describe the spatial positional relationship between a device or feature as shown in the figure and other devices or features.

[0013] See also Figure 1 It can be seen that the overall shape of a new type of manual fine land leveling rake is mainly composed of a handle 1, a rake head frame 2, a thorn tube 3, and a rib cover 4. The rake head frame is in a right-angled U-shape, and corresponding rake head frame shaft holes 5 are provided at the front ends of its two wings, and corresponding rake head frame locking holes 6 are provided at the rear ends. A conical handle tube 7 is fixed at the outer center of the middle section of the rake head frame, which forms a certain elevation angle with the right-angled U-shaped overall surface, and a cylindrical handle 1 with a conical front end is fixed therein; the thorn tube 3 is a cylinder 8 with a certain diameter and a length matching the length between the two wings of the rake head frame 2, and a number of rake teeth 9 of a certain length are evenly and neatly fixed on its surface. A through shaft 10 is provided in the radial center of the cylinder, which is connected in series with the rake head frame shaft holes 5 provided at the front ends of the two wings of the rake head frame; the rib cover 4 is a rib cover 4 with a length exceeding the diameter of the thorn tube 3 and the diameter of the thorn tube 3. On a rectangular frame composed of an opposite side perpendicular to the thorn tube 3 and another opposite side whose length matches the outer width of the two wings of the rake head frame 2 and is parallel to the thorn tube, a corresponding rib cover shaft hole 11 is provided in the middle of the opposite side perpendicular to the thorn tube 3, and a corresponding rib cover locking hole 12 is provided at one end, and the rib cover shaft hole 11 is connected in series through the through shaft 10 provided at the radial center of the thorn tube 3 and the rake head frame shaft hole 5 provided at the front ends of the two wings of the rake head frame, the rib cover locking hole 12 and the rake head frame locking hole 6 provided at the rear ends of the two wings of the rake head frame are fixed by bolts, and a plurality of arc-shaped ribs 13 with arc bottoms close to the cylinder 8 in the thorn tube are fixed on the opposite side of the rectangular frame of the rib cover 4 parallel to the thorn tube 3 in the opposite direction to the conical handle tube 7 with a certain elevation angle, and are evenly staggered and fixed in the same direction with the rake teeth 9 neatly arranged on the thorn tube 3.

[0014] See also Figure 2 A new type of manual fine soil leveling rake head frame can be seen. The rake head frame is in a right-angled U-shape, and corresponding rake head frame axis holes 5 are provided at the front ends of its two wings, and corresponding rake head frame locking holes 6 are provided at the rear ends. A conical handle tube 7 is fixed at the outer center of the middle section of the rake head frame, which forms a certain elevation angle with the right-angled U-shaped overall surface, and a cylindrical handle 1 with a conical front end is fixed therein.

[0015] See also Figure 3 A new type of artificial fine land leveling harrow thorn tube is shown in a top view.
