Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for grain processing, and in particular to a wooden rake for partially leveling the grain surface. Background Technology

[0002] In grain processing, the flatness of the grain surface has a significant impact on the storage and processing quality of the grain. Traditional grain surface leveling tools typically have fixed angles and can only be used for coarse grains, resulting in low efficiency and insufficient flatness. Using these traditional tools, which lack control over flatness, leads to unstable quality after grain processing, affecting storage and sales. Therefore, this invention designs a novel partial grain surface leveling tool that improves the efficiency and precision of grain surface leveling, reduces labor intensity, and can be used not only for coarse but also fine grain surfaces. This is of great significance for improving grain processing quality and storage efficiency. Utility Model Content

[0026] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-3 As shown, the present invention provides a wooden rake for partially leveling grain surfaces, comprising a rake head 100 and a rake rod 200 hinged to the rake head 100, wherein a movable sleeve 300 that can move up and down is installed on the outside of the rake rod 200.

[0028] A rotating disk 101 is installed in the center of the rake head 100. A ball bearing 103, which assists in rotation, is surrounded by an upper outer circumference of the rotating disk 101. The bottom of the rotating disk 101 is installed in the inner cavity of the rake head 100 and pressed against the ball bearing 103. A connecting block 102 is fixedly connected to the rotating disk 101 facing upwards. To facilitate the placement of the ball bearing 105, a ball bearing mounting groove 104 is provided inside the rake head 100. The ball bearing 103 is installed within the ball bearing mounting groove 104. Specifically, the outer periphery of the ball bearing 103 is respectively limited within the side wall of the ball bearing mounting groove 104, on the outer wall of the rotating disk 101, on the bottom upper surface of the rotating disk 101, and on the top inner wall of the rake head 100.

[0029] The bottom end of the rake handle 200 is provided with a rotating head 201. The rotating head 201 is coaxially connected with the connecting block 102. The rake handle 200 is provided with two horizontally arranged mounting grooves 202. A spring 203 is installed in the mounting groove 202. In its natural state, the spring 203 pushes the positioning steel ball 204 at the head outward. Specifically, the rotating head 201 is U-shaped and clamped on the outside of the connecting block 102. The middle of the rotating head 201 and the connecting block 102 are connected by a horizontally arranged rotating shaft. The direction of the rotating shaft is consistent with the long side direction of the rake head 100, which facilitates the hinged movement of the rotating head 201 on the connecting block 102 and facilitates the use of the rake head and the rake handle with the same angle.

[0030] The movable sleeve 300 is provided with limiting holes 301 for matching the installation of positioning steel balls 204. In order to effectively match the structure of the spring 203 on the mounting groove 202 and the positioning steel balls 204, the limiting holes 301 are provided with at least four or more even numbers, so that the movable sleeve 300 can be extended to different ends for fixing. In the positioning state, the positioning steel balls 204 are engaged in the limiting holes 301. In the non-positioning state, the positioning steel balls 204 are pressed into the inner wall of the movable sleeve 300.

[0031] In this design, to facilitate handling, placement, and application of force by operators, a connecting chain 302 is installed at the end of the movable sleeve 300. A hook 303 is provided on the side of the connecting chain 302 away from the movable sleeve 300. The diameter of the rake handle is generally between 3-5 cm, with a smooth surface to reduce operator hand fatigue. Furthermore, the rake head 100 is made of one of the following materials: locust wood, elm wood, or fir wood. In practice, equivalent wood materials can also be used. It has a certain thickness and width to ensure it can withstand a certain amount of pressure and friction when leveling the grain surface. The horizontal cross-section of the rake head 100 is rectangular or trapezoidal, and the edges of the rake head 100 have rounded transitions.

[0032] This utility model includes key components such as a rake head, rake rod, movable sleeve, rotating disk, connecting block, spring and positioning steel ball; a rotating disk is installed in the center of the rake head, and auxiliary rotating balls are surrounded on the outer circumference of the upper part of the rotating disk. The bottom of the rotating disk is installed in the inner cavity of the rake head and pressed under the balls. A connecting block is fixedly connected to the rotating disk facing upward. During use, a rotating head is provided at the bottom of the rake rod. Rotating the rake rod drives the rotating head to rotate, which in turn drives the rotating disk to rotate. The rotating head and the connecting block are coaxially connected, which facilitates the control of the angle between the rake rod and the rake head, and facilitates leveling operations. The rake rod has two horizontally set mounting slots. In actual settings, more than two even numbers can be set. Springs are installed in the slots. In their natural state, the springs push the positioning steel ball at the head outwards. The movable sleeve has a limiting hole for matching the installation of the positioning steel ball. Therefore, by controlling the insertion state between the limiting hole on the movable sleeve and the positioning steel ball, the length of the long rod (the total length of the movable sleeve and the rake rod) can be adjusted, making it suitable for different situations. In addition, a connecting chain 302 is installed at the end of the movable sleeve 300. The side of the connecting chain 302 away from the movable sleeve 300 has a hook 303, which makes it easy for the operator to hold, place, and apply force, making the operation more flexible and convenient.

[0033] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
