Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a digging shovel for a medicinal herb harvester. Background Technology

[0002] With the development of Chinese medicinal herb cultivation technology, the planting area of ​​Chinese medicinal herbs has been expanding year by year, and the harvesting of Chinese medicinal herbs has become an important task for growers.

[0003] According to Chinese Patent Publication No. CN210137615U, a deep digging shovel for a medicinal herb harvester is disclosed. It is installed on the harvester using appropriate bolt holes selected according to the depth of the bottom of the medicinal herb. When the harvester is started, the front plow blade breaks and enters the soil, facilitating the entry of the plow blade body into the soil. The side plow blades cut the soil clods on both sides of the deep soil layer, reducing the resistance when the device moves forward. Reinforcing ribs ensure sufficient rigidity. However, in this technical solution, when digging medicinal herbs at different depths, the side plow blades need to be reinstalled and their positions adjusted, resulting in low adjustment efficiency and affecting the digging efficiency. Therefore, we propose a digging shovel for a medicinal herb harvester. Utility Model Content

[0004] The purpose of this invention is to provide a digging shovel for a medicinal herb harvester, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a digging shovel for a medicinal herb harvester, comprising a plow body and two side plow blades. The plow body is fixedly installed between the two side plow blades near its bottom end. A front plow blade is fixedly installed at the bottom end of the plow body near its front. A connecting plate is fixedly installed at the top of each of the two side plow blades. A mounting sleeve is fitted onto the top of the connecting plate. A long screw is movably passed through the top of the mounting sleeve. The long screw is threadedly connected to a threaded groove on the top of the connecting plate, and the long screw is rotatably connected to the mounting sleeve via a bearing. A hexagonal groove is provided at the top of the long screw. A mounting hole is passed through the mounting sleeve near its top end. A limiting cylinder is fixedly fitted onto the outer wall of the long screw near its top end. The limiting cylinder is slidably connected to the top surface of the mounting sleeve.

[0006] Preferably, reinforcing ribs are fixedly installed on both sides of the mounting plate. By setting the reinforcing ribs, the mounting plate can be supported and its strength can be improved.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1:

[0023] A preferred embodiment of the digging shovel of the medicinal herb harvester provided by this utility model is, for example... Figures 1 to 4 As shown: A digging shovel for a medicinal herb harvester includes a plow body 1 and two side plow blades 3. The plow body 1 is fixedly installed between the two side plow blades 3 near the bottom. A front plow blade 2 is fixedly installed at the bottom of the plow body 1 near the front. A connecting plate 4 is fixedly installed at the top of each of the two side plow blades 3. A mounting sleeve 5 is sleeved on the top of the connecting plate 4. A long screw 7 is movably passed through the top of the mounting sleeve 5. The long screw 7 is threadedly connected to a threaded groove on the top of the connecting plate 4. The long screw 7 is rotatably connected to the mounting sleeve 5 through a bearing. A hexagonal groove 8 is opened at the top of the long screw 7. A mounting hole 6 is passed through the mounting sleeve 5 near the top. A limiting cylinder 11 is fixedly sleeved on the outer wall of the long screw 7 near the top. The limiting cylinder 11 is slidably connected to the top surface of the mounting sleeve 5.

[0024] Specifically, in the above technical solution, when the digging shovel of the medicinal herb harvester is in use, the mounting plate 5 is installed on the medicinal herb harvester using high-strength bolts. Then, when it is necessary to dig medicinal herbs at different depths, a hexagonal wrench can be directly inserted into the hexagonal groove 8. Then, the long screw 7 is rotated by the hexagonal wrench. The long screw 7 drives the connecting plate 4 to move downward, and the connecting plate 4 drives the side plow blade 3 to move downward. This causes the side plow blade 3 to drive the plow body 1 and the front plow blade 2 to move downward, allowing the plow body 1 and the front plow blade 2 to dig into deeper layers of medicinal herbs. Through the above structure, it is convenient for personnel to adjust the side plow blade 3, the plow body 1, and the front plow blade 2 according to the depth of different medicinal herbs, improving the adjustment efficiency and ensuring the digging efficiency of medicinal herbs. This solves the problem in the existing technical solution that when it is necessary to dig medicinal herbs at different depths, the side plow blade 3 needs to be reinstalled and its position adjusted, resulting in low adjustment efficiency and affecting the digging efficiency of medicinal herbs.

[0025] Furthermore, reinforcing ribs 9 are fixedly installed on both sides of the mounting plate 5;

[0026] Among them, by setting the reinforcing rib 9, the mounting sleeve 5 can be supported, thereby improving the strength of the mounting sleeve 5.

[0027] Furthermore, the reinforcing rib 9 is triangular in shape.

[0028] Example 2:

[0029] Based on Embodiment 1, a preferred embodiment of the digging shovel of the medicinal herb harvester provided by this utility model is, for example... Figures 1 to 4 As shown: An L-shaped fixing plate 10 is fixedly installed on the inner side of the mounting sleeve 5. A short screw 12 is threadedly connected to the threaded hole on the L-shaped fixing plate 10. One end of the short screw 12 is rotatably connected to a pressure block 14 through a bearing seat. An annular groove 16 is opened on the outer wall of the limiting cylinder 11. A knob 17 is fixedly installed on the other end of the short screw 12. The pressure block 14 and the L-shaped fixing plate 10 are limited and connected.

[0030] Specifically, in the above technical solution, after the depth adjustment is completed, the knob 17 can be rotated. The knob 17 drives the short screw 12 to rotate, causing the short screw 12 to drive the pressure block 14 to move towards the limiting cylinder 11. Finally, the pressure block 14 causes the anti-slip pad 15 to be squeezed against the inner wall of the annular groove 16, thereby pressing and fixing the long screw 7, improving the stability of the long screw 7 during use, and thus ensuring the stability of the digging depth of the plow body 1. The structure is simple and highly practical.

[0031] Furthermore, an anti-slip pad 15 is fixedly installed at one end of the pressure block 14, and the pressure block 14 corresponds to the position of the annular groove 16;

[0032] By setting the anti-slip pad 15, the friction between the pressure block 14 and the limiting cylinder 11 can be increased, thereby improving the fixing stability.

[0033] Furthermore, a limiting rod 13 is fixedly installed at the other end of the pressure block 14, and the limiting rod 13 movably passes through the L-shaped fixing plate 10;

[0034] The limiting rod 13 can limit the pressure block 14 to ensure its stability during use.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
