Description

Technical Field

[0001] This utility model belongs to the field of forestry afforestation, specifically a planting device for forestry afforestation. Background Technology

[0002] In forestry afforestation operations, pit digging is a core process to ensure the quality and survival rate of seedlings. Especially in small-scale afforestation scenarios such as mountains and hills, flexible and portable planting devices are needed to complete the work. Although the small-scale forestry planting devices currently on the market can make up for the poor terrain adaptability of large machinery, they have significant technical shortcomings in terms of ease of operation and labor intensity control, making it difficult to meet the needs of long-term continuous afforestation operations.

[0003] The core problem with existing small-scale planting devices lies in the "unreasonable design of the human-driven structure": to move the digging component up and down, most devices require workers to use a combination of "bending down and pressing down + raising their legs and pedaling"—during operation, workers must first bend over to apply downward pressure to the drive component at the top of the device, causing the digging component to initially cut into the soil; then they raise their legs to more than 30cm and repeatedly pedal to drive the component to continue moving down. In this operating mode, the body needs to frequently switch between bending over and raising the legs, the waist is always in a state of tension and exertion, and the leg muscles also have to bear extra load. After working for a long time, it is easy to cause problems such as lumbar strain and leg pain, which not only reduces work efficiency but also causes potential damage to the health of workers. Utility Model Content

[0004] The purpose of this utility model is to provide a planting device for forestry afforestation, in order to solve the problem that the existing small planting devices have unreasonable human-driven structure design, which leads to unreasonable operating posture of workers, excessive load on the waist and legs, easy to cause fatigue and low work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a planting device for forestry afforestation, comprising a frame, a lifting assembly, a digging assembly, an upward driving element, moving wheels, and support legs;

[0006] The frame includes a bracket, a guide rod, and a handle. The guide rod is fixedly disposed in the middle of the bracket and extends along the Z-axis direction, and the handle is fixedly disposed at the end of the bracket.

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] As attached Figure 1 To be continued Figure 3 As shown:

[0039] This utility model provides a planting device for forestry afforestation, including a frame 1, a lifting assembly 2, a digging assembly 3, an upward driving element 4, moving wheels 5, and support legs 6; the frame 1 includes a bracket 101, a guide rod 102, and a handle 103. The guide rod 102 is fixedly installed in the middle of the bracket 101 and extends along the Z-axis direction, and is fixed by welding. The weld is reinforced to ensure a firm connection. The handle 103 is fixedly installed at the end of the bracket 101; the lifting assembly 2 is slidably installed on the guide rod 102. The lifting assembly 2 includes a lifting plate 201, a foot pedal 202, and a push-pull unit 203. The lifting plate 201 is slidably connected to the guide rod 102. The device is constructed using high-strength steel plates with anti-corrosion treatment. The foot pedal 202 is fixedly mounted on the lifting plate 201, with anti-slip protrusions on its surface. The push-pull unit 203 is hinged to the side of the lifting plate 201 to assist in its downward movement. The pit-digging assembly 3 is fixedly mounted on the lifting plate 201 to dig tree pits, providing suitable holes for afforestation operations. The upward-moving drive element 4 is located between the lifting plate 201 and the support 101 to drive the lifting plate 201 to move upward and reset, eliminating the need for manual lifting. The moving wheel 5 is fixedly mounted on one side of the bottom of the support 101. The support leg 6 is fixedly mounted on the support 101 at the end away from the handle 103 to support the device and prevent swaying during operation.

[0040] During operation, the worker first holds the handle 103 and uses the moving wheels 5 to push the device to the afforestation work position; then, the outriggers 6 are adjusted to stabilize the device on the ground; subsequently, the digging component 3 is activated, the worker holds the push-pull unit 203 and steps on the foot pedal 202 to drive the lifting plate 201 to move down along the guide rod 102, thus digging a tree pit; after reaching the preset depth, the push-pull unit 203 and foot pedal 202 are released, and the upward drive element 4 drives the lifting plate 201 to reset, completing one digging operation; through the coordinated work of various components, the digging efficiency is effectively improved and the labor intensity of the workers is reduced.

[0041] As attached Figure 1 To be continued Figure 3As shown: In one embodiment of this utility model, the push-pull unit 203 includes a push-pull rod 2031 and a limiting block 2032; one end of the push-pull rod 2031 is hinged to the side of the lifting plate 201, and is made of high-strength aluminum alloy, which is lightweight and high-strength. The push-pull rod 2031 can be rotated around the hinge point in a direction perpendicular to the forward direction of the device, and the rotation angle can reach 180 degrees to adapt to different operating postures of the staff; the limiting block 2032 is fixedly set on the side of the push-pull rod 2031 near the hinge point, and is integrally formed with the push-pull rod 2031, and is used to limit the rotation angle of the push-pull rod 2031 to avoid excessive deflection affecting its use.

[0042] During operation, the operator first flips the push-pull rod 2031 to a suitable angle according to their own standing position and operating habits, and the limit block 2032 ensures that it will not deflect excessively; then, the operator holds the push-pull rod 2031 and applies downward force, which assists the lifting plate 201 to move smoothly down along the guide rod 102; throughout the entire operation, the flexible flipping characteristics of the push-pull rod 2031 allow the operator to avoid frequent adjustments to their standing position, further reducing the difficulty of operation, while the limit block 2032 ensures the safety and stability of the operation.

[0043] As attached Figure 1 To be continued Figure 3 As shown: In one embodiment of this utility model, the digging assembly 3 includes a drive component 301 and a digging drill 302; the drive component 301 is fixedly installed in the middle of the upper surface of the lifting plate 201, and is equipped with a 1.5kW small gasoline engine, which is fixed by bolts. Rubber shock-absorbing pads are provided at the bolt connection to reduce vibration transmission; the digging drill 302 is connected to the output shaft of the drive component 301 through a coupling. The coupling is an elastic coupling, which can compensate for installation errors. The digging drill 302 has a spiral blade structure. The blades are made of manganese steel and have a wear-resistant coating. Different diameter digging drills 302 can be replaced according to the needs of the pit.

[0044] During operation, the staff first checks the status of the drive unit 301 to ensure that the fuel is sufficient and the components are in good working order. Then, the drive unit 301 is started, and its output shaft drives the digging drill 302 to rotate at high speed through the coupling. Subsequently, the lifting plate 201 is driven to move down, and the rotating digging drill 302 cuts into the soil and transports the soil upward to form a tree pit. The spiral blade structure greatly improves the digging efficiency, the wear-resistant material extends the service life of the digging drill 302, and the shock-absorbing pads reduce the impact of the vibration of the drive unit 301 on the device, ensuring the stability of the pit digging process.

[0045] As attached Figure 2 To be continued Figure 3As shown: In one embodiment of this utility model, the upward driving element 4 is a cylindrical helical spring. The upward driving element 4 is sleeved on the outside of the guide rod 102. The spring elastic coefficient is accurately calculated to meet the reset requirements. One end of the upward driving element 4 is fixedly connected to the upper surface of the lifting plate 201, and the other end is fixedly connected to the lower surface of the bracket 101. Both are fixed by welding. The weld is reinforced to prevent the spring from falling off when it extends or retracts.

[0046] During operation, the worker first drives the lifting plate 201 to move downwards, at which time the upward driving element 4 is compressed and stores elastic potential energy. When the digging operation is completed, the worker releases the force on the lifting plate 201, and the upward driving element 4 releases the elastic potential energy, generating an upward thrust. Under the action of the thrust, the lifting plate 201 moves smoothly upwards along the guide rod 102, driving the digging component 3 to detach from the pit and achieve automatic reset. There is no need for manual lifting of the lifting plate 201, which significantly reduces the labor intensity of the workers and improves the continuity of the operation.

[0047] As attached Figure 2 To be continued Figure 3 As shown: In one embodiment of this utility model, the support leg 6 includes a support plate 601 and a threaded telescopic rod 602; the support plate 601 is fixedly mounted on the bracket 101 and connected to the bracket 101 by bolts to ensure stability; the threaded telescopic rod 602 is fixedly mounted below the support plate 601 and uses a threaded connection to achieve length adjustment. The bottom of the threaded telescopic rod 602 has a conical structure, is hardened, has high hardness and good wear resistance, and is easy to insert into the ground.

[0048] During operation, the worker first moves the device to the work position and then rotates the threaded telescopic rod 602 to adjust its extension length. As the adjustment deepens, the conical bottom gradually inserts into the ground, forming a stable support with the moving wheel 5. Once the device is securely fixed, the worker starts the digging assembly 3 to begin work. The length of the threaded telescopic rod 602 can be flexibly adjusted according to the flatness of the ground, ensuring that the device can operate stably in different terrains and effectively preventing the device from shaking during digging and causing the pit to tilt.

[0049] As attached Figure 1 To be continued Figure 3 As shown: In one embodiment of this utility model, several guide rods 102 are provided, and in this embodiment there are two. The several guide rods 102 are symmetrically distributed in the middle of the bracket 101 to ensure the guiding balance of the lifting plate 201. The lifting plate 201 is provided with guide holes that are adapted to the guide rods 102. The hole diameter is highly accurate to ensure smooth sliding. A polytetrafluoroethylene wear-resistant bushing is fixedly provided in the guide hole. The bushing has good self-lubricating and wear-resistant properties to reduce the frictional loss between the lifting plate 201 and the guide rods 102.

[0050] During operation, the operator first drives the lifting plate 201 to move up and down. Under the action of two symmetrically distributed guide rods 102, the lifting plate 201 always remains horizontal and will not deviate or tilt. The polytetrafluoroethylene wear-resistant bushing in the guide hole reduces the frictional resistance between the lifting plate 201 and the guide rods 102, making the lifting process smoother, reducing component wear, extending the overall service life of the device, and ensuring continuous and stable digging operations.

[0051] As attached Figure 1 To be continued Figure 3 As shown: In one embodiment of this utility model, the outer surface of the movable wheel 5 is provided with anti-slip texture and is made of high elastic rubber material, which has good shock absorption and grip.

[0052] When in operation, the staff first hold the handle 103 and push the device to move it around the afforestation site. On muddy or rugged roads, the anti-slip texture on the outer surface of the moving wheels 5 can enhance the grip and prevent slipping, while the high-elasticity rubber material reduces the impact on the ground when the device is moved. The convenient and quick movement characteristics allow the staff to carry the device without spending too much physical effort, improving work efficiency and expanding the scope of application of the device.

[0053] In one embodiment of this utility model, the outer surface of the grip 103 is covered with an anti-slip rubber sleeve, and the surface of the rubber sleeve is provided with anti-slip texture to increase the friction between the hand and the grip 103 and prevent the hand from slipping due to sweat.

[0054] When working, the hands firmly grip the handle 103 while pushing the device or operating it. The anti-slip rubber sleeve and texture effectively prevent slippage, ensuring stable operation, improving the comfort and safety of operation, reducing hand fatigue caused by long-term work, and allowing workers to complete afforestation digging operations more efficiently.

[0055] Working principle: The staff first pushes the device to the target operation position for forestry afforestation. After reaching the position, the support leg 6 on the support frame 101 is adjusted: the threaded telescopic rod 602 of the support leg 6 is rotated so that the conical bottom is inserted into the ground, which cooperates with the moving wheel 5 to support and fix the device from different positions to prevent the device from shaking or shifting during operation.

[0056] Next, the drive unit 301 (a 1.5kW small gasoline engine) of the digging assembly 3 is activated. The drive unit 301 drives the digging drill 302 to rotate at high speed via a flexible coupling. At this time, the operator holds the push-pull rod 2031 of the lifting assembly 2 (adjusting the tilt angle according to operating habits, with a limit block 2032 to prevent over-rotation) and simultaneously steps on the foot pedal 202 on the lifting plate 201, applying downward force. Under the combined action of the pushing force and the stepping force, the lifting plate 201 moves smoothly down along the guide rod 102 (sleeved with a polytetrafluoroethylene wear-resistant bushing) in the middle of the support 101, driving the rotating digging drill 302 to cut into the soil. The spiral blades transport the soil upward, gradually forming a tree pit that meets the requirements for afforestation.

[0057] Once the digging drill 302 has reached the preset depth for the tree pit, the worker releases the push-pull rod 2031 and the foot pedal 202. At this time, the upward drive element 4 (cylindrical helical spring) sleeved on the outside of the guide rod 102 releases its stored elastic potential energy, generating an upward thrust that drives the lifting plate 201 to smoothly move upward and reset along the guide rod 102, causing the digging drill 302 to disengage from the pit. Finally, the drive element 301 is closed, and the threaded telescopic rod 602 is rotated in the opposite direction to lift it off the ground. The worker then holds the handle 103 and pushes the device to the next working position, repeating the above steps to perform the next tree pit digging operation until the forestry afforestation pit digging task for the area is completed.

[0058] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
