Description

Technical Field

[0001] The utility model belongs to the technical field of afforestation equipment, in particular to an afforestation pit digging device. Background Art

[0002] Afforestation is the production activity of creating or renewing forests on forestry land by planting seedlings, grafting or sowing. To be precise, if the planting area is large and can form forests and forest environments in the future, it is called afforestation. If the area is small and cannot form forests or forest environments, it can only be called tree planting or planting trees, but not afforestation.

[0003] The prior art discloses a rapid pit digging equipment for mountain afforestation (CN219812474U), which includes an outer frame assembly and a pit digging assembly arranged on the front side of the outer frame assembly, the outer frame assembly includes an outer frame, a hydraulic rod fixed to the lower surface of the inner frame of the outer frame, and a driving wheel group rotatably connected at the lower ends of both sides of the outer frame; the pit digging assembly includes a power unit, a connecting plate fixed to the lower end of the power unit, a reduction gear box fixed to the center position of the lower surface of the connecting plate, a drill rod fixed to the lower end of the reduction gear box, and a drill bit fixed to the lower end of the drill rod.

[0004] After searching, it was found that the size of the pit required for digging the pit was different due to the different sizes of vegetation. The device did not take into account the size of the pit required for digging the pit when it was used. This resulted in the need to manually determine the size of the pit and then manually push the machine to complete the digging, which not only increased the labor intensity of the staff but also wasted a lot of time. In addition, the device used a hydraulic rod to control the extension and retraction of the drill bit. The softness of the soil was not taken into consideration during use, and no relevant loosening facilities were set up. This resulted in the drill bit being blocked after penetrating the ground because the soil was too moist or unable to enter the deep soil because the soil was too hard. This not only affected the digging of the pit but also caused damage to the drill bit, seriously affecting the practicability of the device.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0029] A afforestation pit digging device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes an outer frame 10, both sides of the outer frame 10 are rotatably provided with wheel frames, the triangular parts of the wheel frames are rotatably provided with tires for movement, and the outer frame 10 slides on the ground through the wheel frames and the tires; a pushing component, the pushing component is rotatably provided inside the outer frame 10, and the pushing component includes an inner frame 12, a forward and reverse screw rod 14, a connecting rod 15, a booster block 16 and a pushing plate 17, the inner frame 12 is rotatably provided inside the outer frame 10, the forward and reverse screw rod 14 is rotatably provided inside the inner frame 12, and the pushing plate 17 is slidably provided inside the outer frame 10 Inside the inner frame 12, the boost block 16 is threadedly connected to the forward and reverse screw rods 14, and the boost block 16 and the pushing plate 17 are both rotatably connected to the connecting rod 15; the displacement component, the displacement component is slidably arranged inside the pushing plate 17, the displacement component includes a moving plate 18, a spiral column 21, a loosening drill bit 22 and a clamping block 24, the loosening drill bit 22 is fixedly arranged at the bottom of the spiral column 21, the spiral column 21 is rotatably arranged inside the moving plate 18, the clamping block 24 is elastically connected to one side of the moving plate 18, and the clamping block 24 is clamped inside the pushing plate 17.

[0030] The working principle is as follows: the height of the outer frame 10 is greater than or equal to the height of the inner frame 12. When in use, the pit opening position is determined by moving the position of the movable plate 18 in the push plate 17, and then the block 24 is used to limit the connection between the movable plate 18 and the push plate 17. This process avoids the tediousness of manually pushing the machine, reduces the labor burden of the staff and saves time; by rotating the forward and reverse screw rods 14, the booster block 16 can push the connecting rod 15, so that the other end of the connecting rod 15 pushes the push plate 17 to move up and down, so that the movable plate 18 moves with the push plate 17, thereby driving the spiral column and the loosening drill bit to dig a pit on the ground. Under the rotation of the loosening drill bit, the soil will be reclaimed to a certain extent, and then transported out through the surface of the spiral column. This not only facilitates pit opening, but also reduces damage to the loosening drill bit itself, thereby ensuring the practicality of the device.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a top plate is arranged on the top of the outer frame 10, a rotating hole is opened inside the top plate, a cylinder is rotatably connected in the rotating hole through a bearing, a handle 11 is fixedly connected to the top of the cylinder, and the bottom end of the cylinder is fixedly connected to the inner frame 12; Figure 3 and Figure 4 As shown, the inner frame 12 is a square frame, and a through hole is opened inside the inner frame 12. The forward and reverse screw rod 14 rotates and passes through the through hole. The outer wall surface of the inner frame 12 is fixed with a bracket 20 by bolts. The inner frame 12 is fixed with a forward and reverse motor 13 through the bracket 20. The output end of the forward and reverse motor 13 is connected to one end of the forward and reverse screw rod 14; Figure 3 As shown, both ends of the positive and negative screw rods 14 are respectively threadedly connected with booster blocks 16 with different pitch directions, and different rotating columns are fixedly arranged on both sides of the booster blocks 16. The booster blocks 16 are rotatably connected with different connecting rods 15 through the rotating columns on both sides. There are four connecting rods 15, and the other ends of the four connecting rods 15 are rotatably connected to the top of the push plate 17; Figure 3 As shown, the push plate 17 is composed of a square plate, a square groove block and a trapezoidal block. Different cylinders are fixedly arranged inside the two ends of the trapezoidal block. Four connecting rods 15 are rotatably connected to the two ends of the two cylinders. A square groove is opened on the inner wall of the inner frame 12, and the square plate slides up and down in the square groove.

[0032] The working principle is as follows: the forward and reverse motor 13 is externally connected to a controller, a controller and a sensor. When it senses that the forward and reverse screw rod 14 cannot push the booster block 16 to move, the controller will control the forward and reverse motor 13 to automatically realize forward and reverse rotation. When in use, the forward and reverse motor 13 drives the forward and reverse screw rod 14 to rotate, and the booster blocks 16 at both ends of the forward and reverse screw rod 14 move inward at the same time. At the same time, the booster block 16 drives one end of the connecting rod 15 to move inward, and the other end of the connecting rod 15 simultaneously pushes the pushing plate 17 to move downward, and at this time, the pushing plate 17 pushes the displacement assembly downward. When the controller senses that the two booster blocks 16 are close to each other and can no longer move, the controller will control the forward and reverse motor 13 to rotate in the opposite direction. At this time, the booster blocks 16 at both ends move toward the two ends of the forward and reverse screw rod 14 at the same time. At this time, the booster block 16 drives one end of the connecting rod 15 to move outward, and at the same time, the other end of the connecting rod 15 pulls the trapezoidal block of the pushing plate 17, and at this time, the connecting rod 15 drives the pushing plate 17 to move upward, and at this time, the pushing plate 17 drives the entire displacement assembly to move upward.

[0033] like Figure 3 and Figure 5 As shown, a clamping groove 23 is provided on one side of the square slot block of the push plate 17, and a clamping block 24 is clamped inside the clamping groove 23. A spring 25 is fixedly provided on one side of the clamping block 24. The clamping block 24 is elastically connected to the moving plate 18 through the spring 25, and the moving plate 18 slides in the square slot block; Figure 4 As shown, the loosening drill bit 22 is a hemispherical structure, and six fan-shaped blades are arranged on the surface of the loosening drill bit 22. A stepped frustum is arranged between every two blades. The loosening drill bit 22 is fixedly arranged on the bottom surface of the spiral column 21. A through hole is opened inside the movable plate 18, and an adaptive bearing is arranged in the through hole. The movable plate 18 is rotatably connected to the loosening drill bit 22 through the bearing. Another bracket 20 is fixed to the top surface of the movable plate 18 by bolts. A rotating motor 19 is fixedly arranged on the movable plate 18 through another bracket 20, and the output end of the rotating motor 19 is connected to the top surface of the spiral column 21.

[0034] The specific implementation is as follows: at least three notches need to be opened in the positioning groove 23. First, the radius of the pit is determined according to the size of the pit. With the handle 11 as the center of the circle, the position of the moving plate 18 is determined, and the moving plate 18 is controlled to reach the appropriate notch of the positioning groove 23. At this time, the distance from the center of the moving plate 18 to the center of the handle 11 is the radius of the pit. After the position is determined, the card block 24 is pulled to make the card block 24 engage in the positioning groove 23, and the spring 25 is used to make the moving plate 18 and the card block 24 clamp the inner wall of the positioning groove 23 at the same time, and then the rotating motor 19 and the forward and reverse motor 13 are started to rotate. The motor 19 drives the spiral column 21 to rotate, the spiral column 21 drives the loosening drill bit 22 to rotate, the forward and reverse motors 13 drive the forward and reverse screws 14 to rotate, the booster block 16 pushes the connecting rod 15, the connecting rod 15 helps the pushing plate 17 to move up and down, the pushing plate 17 carries the moving plate 18 and the blocking block 24 to move up and down at the same time to achieve digging of the ground. At this time, the handle 11 is rotated, the handle 11 drives the inner frame 12 to rotate, the pushing component and the displacement component in the inner frame 12 will rotate with the rotation of the inner frame 12, and at this time, the spiral column 21 and the loosening drill bit 22 dig a hole with the handle 11 as the center of the circle.
