[0001] The utility model relates to the technical field of trenching devices, in particular to a trenching device for forestry and afforestation. Background Art

[0002] With the gradual development of forestry, when planting trees, it is usually necessary to dig trenches and then plant the trees in the trenches. In order to improve the efficiency of the work, a pit digging device is usually used to automatically dig pits at appropriate locations.

[0003] A trenching device for forestry and afforestation disclosed in Chinese patent CN214545504U is suitable for trenching operations when planting small trees. The operation is simple and convenient. However, while solving the problem, the trenching device for forestry and afforestation has the following defects:

[0004] 1. When the device is used to dig a pit, it is necessary to rotate the inner ring plate and fix the device with the inner ring plate, and then dig a pit through the trenching assembly. Since the device needs to be moved once each time a pit is dug, the setting of the inner ring plate easily reduces the working efficiency of the device when digging a pit;

[0005] 2. When installing the trenching assembly, the fixing plate and the connecting plate need to be in contact with each other and then connected together by bolts. During this process, the trenching assembly needs to be pushed upward to ensure that the fixing plate and the connecting plate are in full contact with each other, which makes the installation of the trenching assembly more laborious. Utility Model Content

[0008] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a trenching device for forestry afforestation, including a mounting frame, a hydraulic cylinder is arranged on the top of the mounting frame, a movable plate is arranged on the output end of the hydraulic cylinder, a trenching assembly is arranged on the bottom of the movable plate, the top of the movable plate is movably connected to a limiting column, the bottom end of the limiting column is fixedly connected to a fixed plate, and a spring is arranged on the outer side of the limiting column.

[0009] Preferably, according to any of the above solutions, two limiting columns and fixing plates are symmetrically arranged on the moving plate. A plug cone is fixedly connected to the bottom of the fixing plate. After the fixing plate comes into contact with the ground, the plug cone can be directly inserted into the soil, and the setting of the plug cone makes the fixing of the device by the fixing plate relatively stable.

[0010] Preferably, according to any of the above solutions, a motor is fixedly installed on the top of the moving plate. The output end of the motor penetrates the moving plate. The output end of the motor is fixedly connected to a mounting frame. A U-shaped plate is arranged inside the mounting frame. The trench digging assembly is fixedly connected to the bottom of the U-shaped plate. The motor can drive the trench digging assembly to rotate through the mounting frame and the U-shaped plate. At the same time, when installing the trench digging assembly, the U-shaped plate is directly inserted into the mounting frame. This setting makes it unnecessary to push the trench digging assembly upward when fixing the U-shaped plate inside the mounting frame, and the operation is relatively convenient.

[0011] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0012] 1. With the mutual cooperation of the moving plate, limiting columns, springs and fixing plates, when the moving plate drives the trench digging assembly to move downward, the fixing plate comes into contact with the ground first and completes the fixing of the mounting frame, and then the trench digging assembly performs trench digging operations.

[0028] Embodiment 6: A universal wheel 15 is fixedly installed at the bottom of the mounting frame 1. A push handle 16 is fixedly connected to the back of the mounting frame 1. The mounting frame 1 is pushed through the push handle 16, and the mounting frame 1 is moved to a suitable position with the assistance of the universal wheel 15.

[0029] The working principle of the utility model is as follows: when in use, the device is moved to a suitable position by the push handle 16 and the universal wheel 15, and then the motor 11 is started, so that the motor 11 drives the ditching assembly 4 to rotate, and the hydraulic cylinder 2 is started at the same time, so that the hydraulic cylinder 2 pushes the movable plate 3 downward. When the movable plate 3 moves downward, the fixed plate 6 is pushed by the spring 7 to contact the ground first and the insert cone 8 is directly inserted into the soil. As the movable plate 3 continues to move downward, the rotating ditching assembly 4 also contacts the ground and starts to perform ditching operations. When the ditching operations are completed, the hydraulic cylinder 2 drives the movable plate 3 to move upward, so that the movable plate 3 drives the ditching assembly 4 to move upward. When the movable plate 3 moves to a certain height, the fixed plate 6 can be pulled upward by the limit column 5 so that the fixed plate 6 is no longer in contact with the ground. At this time, the device can be directly moved and moved directly to the next position to repeat the above operations.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Move the device to a suitable position and start the hydraulic cylinder 2 so that the hydraulic cylinder 2 pushes the movable plate 3 to move downward. At this time, the fixed plate 6 is first in contact with the ground under the push of the spring 7 and the insert cone 8 is directly inserted into the interior of the soil. As the movable plate 3 continues to move downward, the fixed plate 6 and the movable plate 3 squeeze the spring 7 while the limit column 5 continues to move toward the upper side of the movable plate 3. In this process, the trenching assembly 4 starts to dig trenches on the soil. In summary, when the device is digging trenches on the soil, the fixed plate 6 is driven by the movable plate 3 to fix the mounting frame 1 first, and then the trenching assembly 4 performs trenching operations. The entire operation process is relatively coherent, and only the hydraulic cylinder 2 needs to be driven, so that the working effect of the device during pit digging operations is improved.

[0032] 2. When installing the trenching assembly 4, directly insert the shaped plate 13 into the interior of the mounting frame 12, so that the shaped plate 13 can support the trenching assembly 4 through the mounting frame 12, so that when the shaped plate 13 is fixed to the interior of the mounting frame 12 by bolts, there is no need to push the trenching assembly 4 upward. The arrangement of the shaped plate 13 and the mounting frame 12 makes it relatively labor-saving when installing the trenching assembly 4.
