Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a forestry afforestation and land preparation device. Background Technology

[0002] Forestry afforestation land preparation equipment is a type of land preparation equipment used before afforestation. It mainly includes land preparation plows, harrows, shovels, excavators, etc. These devices perform deep plowing, tilling, and leveling of the land before afforestation to provide a good soil environment and air for the growth of seedlings and promote their growth.

[0003] According to the patent document with publication number CN222750844U, a general-purpose motor drives the mounting shaft and the soil-turning blade to rotate, and performs soil turning operations on the afforestation land. During the soil turning process, the arc-shaped structure of the arc-shaped pressing plate reduces the splashing of soil. At the same time, the operation of the electric hydraulic cylinder drives the L-shaped connecting rod, the slider and the arc-shaped pressing plate to move downward, so that the plate structure of the arc-shaped pressing plate can flatten the turned soil.

[0004] The patent document states that during the soil turning process, stones in the soil may be turned to the surface. As the curved pressing plate compresses the soil, the stones may become embedded in the soil layer, which is not conducive to digging pits for subsequent planting. If there are too many stones, it may accelerate the loss of water in the soil. In addition, some weeds are turned up during the soil turning process. The roots and stems of these weeds will entangle in the soil turning structure, affecting the efficiency of soil turning. At the same time, some weeds will cover the soil surface, and the weed seeds on the soil surface will fall to the ground and grow rapidly, competing with the planted seedlings for nutrients and affecting the growth of the seedlings.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-7 As shown, a forestry afforestation land preparation device includes a land turning mechanism 1, a leveling mechanism 2, and a roller pressing mechanism 3.

[0030] In this embodiment: the roller pressing mechanism 3 includes two supports 32, a crossbar 35 is fixed between the two supports 32, a hydraulic rod 31 is provided in the middle of the crossbar 35, a rotating roller 33 is provided on the lower side of the supports 32, and multiple spring strips 34 are fixed on the outer side of the rotating roller 33. The multiple spring strips 34 are arranged in a ring. The two ends of the rotating roller 33 are rotatably connected to the two supports 32. The telescopic part of the hydraulic rod 31 is hinged to the crossbar 35. The telescopic part of the hydraulic rod 31 is used to push the crossbar 35 to make the rear ends of the two supports 32 flip downward. By flipping the rear ends of the two supports 32 downward, the rotating roller 33 is pressed on the ground after the soil is turned over. During this process, the stones after the soil is turned over will be squeezed into the rotating roller 33 from between the multiple spring strips 34, and the collection of stones is completed.

[0031] In this embodiment: the leveling mechanism 2 includes a collection trough 22, a flap 21 is provided on the front side of the collection trough 22, and multiple mounting rings 23 are provided on the rear side of the collection trough 22. The multiple mounting rings 23 are all sleeved on the outside of multiple spring strips 34. Each mounting ring 23 has an arc hook fixed on its outside for hooking weeds. The spring strips 34 are fixedly connected to the inside of the mounting rings 23. Multiple slots are opened on the side of the collection trough 22 near the rotating roller 33. The arc hooks of the multiple mounting rings 23 correspond to the multiple slots. The rotating roller 33 drives the multiple mounting rings 23 to rotate synchronously. The arc hooks on the mounting rings 23 are used to hook up the roots and stems of the weeds after the soil is turned. These hooked weed roots and stems are turned into the collection trough 22 as the rotating roller 33 flips. The arc hooks turn through the slots of the collection trough 22, thereby leaving the weed roots and stems in the collection trough 22. Then, the mounting rings 23 continue to collect the weed roots and stems as the rotating roller 33 continues to rotate.

[0032] In this embodiment: the tilling mechanism 1 includes a frame 11, a mounting frame 12 fixed to the top of the frame 11, a gearbox 13 fixed in the middle of the frame 11, a tilling shaft 14 at the lower end of the gearbox 13, multiple tilling blades 15 fixed to the outside of the tilling shaft 14, two supports 32 rotatably connected to the front ends of the frame 11 on both sides, a hydraulic rod 31 fixed part hinged to the rear side of the mounting frame 12, the upper end of the flip plate 21 hinged to the rear side of the frame 11, the mounting frame 12 fixedly connected to the lifting arm of the tractor, and the input shaft of the gearbox 13 fixedly connected to the universal joint of the tractor. The mounting frame 12 and gearbox 13 are fixedly supported by the frame 11. The mounting frame 12 is fixedly connected to the lifting arm of the tractor. The input shaft of the gearbox 13 is fixedly connected to the universal joint of the tractor. The tractor drives the lifting arm of the frame 11 to lift the mounting frame 12 and the frame 11 up and down. The universal joint of the tractor drives the input shaft of the gearbox 13 to rotate. The gear inside the gearbox 13 drives the turning shaft 14 to rotate. The rotation of the turning shaft 14 drives multiple turning blades 15 to turn the soil on the ground.

[0033] Working principle: When in use, the lifting arm of the tractor drives the mounting frame 12 to tilt downwards, which causes the soil-turning blades 15 to touch the ground. Then, the universal joint of the tractor drives the input shaft of the gearbox 13 to rotate. The gear inside the gearbox 13 drives the soil-turning shaft 14 to rotate. The rotation of the soil-turning shaft 14 drives multiple soil-turning blades 15 to turn the soil on the ground.

[0034] During the soil turning process, the horizontal bar 35 is pushed downward by the extension part of the hydraulic rod 31. The horizontal bar 35 will drive the rear ends of the two supports 32 to turn downward with their front ends as the center. Then, the rotating roller 33 at the rear end of the support 32 presses on the ground after turning. The entire device is moved to turn the soil by the movement of the tractor. During this process, the soil is leveled a second time by the rotating roller 33 pressing on the ground after turning. As the rotating roller 33 moves, it will press over the exposed stones after turning. At the same time, the adjacent spring strips 34 on the outside of the rotating roller 33 will be squeezed and deformed by the stones. At the same time, the elasticity of the adjacent spring strips 34 will clamp the stones. The clamped stones will be gradually pressed into the cage-like structure composed of multiple spring strips 34 and rotating rollers 33 as the rotating roller 33 rotates, thus completing the stone collection process.

[0035] Furthermore, when the rear ends of the two supports 32 are flipped downwards, the two supports 32 will drive the collection trough 22 to move downwards, thereby pressing the lower end of the flip plate 21 onto the soil surface after turning over. Then, the lower side of the flip plate 21 prevents soil from splashing during turning over, and the flip plate 21 can also perform the first rolling and flattening of the soil. In addition, multiple mounting rings 23 will rotate synchronously with the rotating roller 33. When the arc hook on the outer side of the rotating roller 33 rolls over the soil and flips upwards, the arc hook will hook the roots and stems of weeds in the soil upwards, and with the rotation of the rotating roller 33, the roots and stems of weeds will be hooked up and turned into the collection trough 22. Through the slot on the collection trough 22 and the arc hook on the outer side of the mounting ring 23, the roots and stems of weeds will be blocked in the collection trough 22, while the arc hook of the mounting ring 23 will flip out of the collection trough 22 to continue to hook the roots and stems of weeds.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
