Description

Technical Field

[0001] The utility model relates to the technical field of cultivators, in particular to an agricultural cultivator. Background Art

[0002] A cultivator is a common agricultural machine, mainly used for tilling the soil, breaking the soil hardpan layer, improving the soil structure, increasing the soil air permeability and water permeability, thereby promoting the growth of crops. This kind of machine is suitable for a variety of working environments, including field tillage, ditching and ridging, plastic greenhouses, tobacco, nurseries, orchards, and vegetable gardens.

[0003] The existing cultivators mainly achieve the purpose of cultivating or leveling the land by the rotation of the blades. With the high-speed rotation of the blades, soil and dust will splash during the soil loosening process. Since the operator needs to always manually hold the handle to push the movement of the machine body throughout the soil loosening process, the splashing soil and dust will splash onto the operator's shoes and legs, not only polluting the operator's clothes, but also scratching the skin when the operator works in shorts. For this reason, we propose an agricultural cultivator to solve the above problems. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1-4 , an agricultural soil loosener, including a soil loosener body 1. A blade 15 is installed at the bottom end of the soil loosener body 1, and a first soil retaining plate 2 is distributed on the side of the blade 15. The connection method and specific working principle of the soil loosener body 1 and the blade 15 are prior art and will not be elaborated here. Second soil retaining plates 3 are symmetrically arranged on both sides of the first soil retaining plate 2. Installation plates 14 are symmetrically welded to the top end of the first soil retaining plate 2, and the interiors of the installation plates 14 are all connected to the soil loosener body 1 through bolts. Through the mutual cooperation of the installation plates 14 and the bolts, the first soil retaining plate 2 can be easily installed on the side of the soil loosener body 1. U-shaped blocks 4 are symmetrically connected to both ends of the first soil retaining plate 2, and rotating blocks 5 are distributed inside the U-shaped blocks 4. The outer sides of the rotating blocks 5 are connected to the ends of the second soil retaining plates 3. A rotating shaft 6 is inserted into the interior of the rotating block 5, and the bottom end of the rotating shaft 6 is connected to the inner wall of the U-shaped block 4 through a bearing. The top end of the rotating shaft 6 extends above the U-shaped block 4 and is provided with a limiting component. During use, through the mutual cooperation of the rotating block 5 and the rotating shaft 6, the angle of the second soil retaining plate 3 can be adjusted, thereby improving the soil blocking effect. The limiting component includes a square rod 7. A square groove is opened at the top end of the rotating shaft 6, and the square rod 7 is inserted into the interior of the square groove. A limiting rod 8 is connected to the top end of the square rod 7. Card slots adapted to the limiting rod 8 are evenly opened on the upper side of the U-shaped block 4. Since the square rod 7 is set in a certain direction, it rotates together with the rotating shaft 6. Through the setting of the limiting rod 8, the second soil retaining plate 3 rotated to the required angle can be limited to prevent the second soil retaining plate 3 from easily shifting and affecting the normal blocking.

[0021] Furthermore, referring to Figure 4 , it can be known that a connecting spring 9 is vertically connected to the bottom end of the square rod 7, and the other end of the connecting spring 9 is connected to the inner wall of the square groove. Through the setting of the connecting spring 9, the connection between the square rod 7 and the rotating shaft 6 can be realized to prevent the limiting rod 8 and the rotating shaft 6 from being lost after separation.

[0022] Furthermore, referring to Figure 3It can be known that a vertical rod 11 is provided on one side of the first retaining plate 2 close to the blade 15, and fixing blocks 10 are respectively connected to the upper and lower ends of the vertical rod 11. The side of the fixing block 10 is connected to the first retaining plate 2. A scraping strip 12 is inserted into the interior of the vertical rod 11, and the scraping strip 12 is arranged in a U-shaped structure. When the two second retaining plates 3 are adjusted to be perpendicular to the first retaining plate 2, by pulling the U-shaped scraping strip 12 up and down, the inner walls of the first retaining plate 2 and the second retaining plate 3 can be quickly cleaned, so as to prevent the soil from always adhering to the outer surfaces of the first retaining plate 2 and the second retaining plate 3, resulting in rust, and thus the service life of the first retaining plate 2 and the second retaining plate 3 can be guaranteed.

[0023] Further, referring to Figure 3 It can be known that a magnetic strip 13 is connected to the upper side of the scraping strip 12, and a magnetic block adapted to the magnetic strip 13 is connected to the lower side of the mounting plate 14. The magnetic strip 13 and the magnetic block have opposite magnetic polarities. Therefore, the scraping strip 12 can be adsorbed under the mounting plate 14 when not in use, so as to realize the fixing operation of the scraping strip 12.

[0024] Further, referring to Figure 2 It can be known that grooves are uniformly formed at the bottom ends of the first retaining plate 2 and the second retaining plate 3, and balls are distributed in the grooves. The grooves and the balls are not shown in the figure. Through their mutual cooperation, the first retaining plate 2 and the second retaining plate 3 can be effectively prevented from directly contacting the ground rigidly, so as to realize the protection operation of the bottoms of the first retaining plate 2 and the second retaining plate 3.

[0025] Working principle: When the utility model is in use, the staff can first push the device to the area where soil needs to be loosened. Before loosening the soil, the staff can successively pull up the limiting rod 8, so that the bottom end of the limiting rod 8 is withdrawn from the clamping groove inside the U-shaped block 4. Then the staff can push the second retaining plate 3 to an appropriate angle. When the second retaining plate 3 rotates, the rotating block 5 and the rotating shaft 6 rotate simultaneously. Then the staff can stop pulling the limiting rod 8 so that its bottom end is inserted into the corresponding clamping groove at the top of the U-shaped block 4 to realize the adjustment of the second retaining plate 3. After the angles of the two second retaining plates 3 are adjusted, the staff can loosen the soil by rotating the blade 15. During the whole process of loosening the soil, through the arrangement of the first retaining plate 2 and the two second retaining plates 3, it is convenient to realize the blocking of the soil;

[0026] In addition, after the soil loosening is completed, the staff can pull the limit rod 8 again, so that the two groups of second retaining plates 3 can be rotated to a state perpendicular to the first retaining plate 2. After completion, the staff can pull the scraping bar 12 so that its outer side contacts the inner walls of the first retaining plate 2 and the second retaining plate 3, thereby quickly cleaning the mud and ash remaining inside the first retaining plate 2 and the second retaining plate 3, and effectively improving the cleaning efficiency of the staff for this device. The above is the entire working principle of the present utility model.

[0027] In the present utility model, the installation methods, connection methods or setting methods of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indexes of all of its components are its own technologies. As long as the beneficial effects can be achieved, they can be implemented, so no more details will be given.
