Description

Technical Field

[0001] This utility model relates to a soil filling device, specifically a soil filling device for efficient poplar cultivation, belonging to the field of poplar transplanting technology. Background Technology

[0002] To improve the survival rate of poplar transplants and reduce damage during transportation, it is best to transplant poplar seedlings that are two years old or older with a soil ball. However, this method of cultivation results in a corresponding increase in the size of the planting pit. To improve the efficiency of digging pits, small excavators are used to dig pits when transplanting in large quantities (such as in forest farms and farmland shelterbelts), and the excavated soil is piled around the planting pit.

[0003] Unlike the process of digging a hole, once the sapling is placed in the planting hole, in order to avoid the excavator damaging the sapling or the shovel filling force causing the sapling to tilt or fall over, the soil must be manually backfilled into the planting hole with a shovel. The transplanting workers spend a long time backfilling the soil, and the high labor intensity leads to low efficiency in the backfilling work.

[0004] In summary, how to propose a soil filling device to address the aforementioned technical problems has become a pressing issue for those skilled in the art. Utility Model Content

[0007] The folding support unit is installed on the lower end face of the support base, which is fixedly connected to the hand tractor. The lower end face of the support base is integrally provided with several protruding tenons in a circumferential array.

[0008] A handwheel and an angle limit plate are fixed to both ends of the support spindle.

[0009] The support spindle is slidably connected to the support base, and a first compression spring and a washer are installed on the support spindle. The two ends of the first compression spring abut against the upper end surface of the support base and the washer, respectively.

[0010] The upper surface of the angle limiting plate has several grooves arranged in a circular array, which are matched with the tenons. The lower surface of the angle limiting plate is fixed to the bulldozer plate.

[0011] Furthermore, the folding support unit includes a fixed base, support legs, a slider, and a second compression spring.

[0012] The lower end face of the fixed base is fixedly connected to the support base, and two limiting grooves are opened on the circumferential surface of the fixed base.

[0013] The support leg is hinged to the fixed base, and a limit part is integrally provided on the support leg.

[0014] The second compression spring and the slider are both sleeved on the support leg, and the two ends of the second compression spring abut against the limiting part and the lower end face of the slider, respectively.

[0015] The upper surface of the slider is integrally provided with a locking tenon, which is adapted to the limiting groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model has a simple structure and is easy to operate. It can be easily transported and moved in the forest by being pulled by a hand tractor 500.

[0033] The support leg 820 is hinged to the fixed base 810, and a limiting part is integrally provided on the support leg 820. The length of the support leg 820 is greater than the distance between the support base 100 and the lower surface of the bulldozer 600.

[0046] Working principle

[0047] The fixed base 810 is fixedly connected to the lower end face of the support base 100, and the support leg 820 is hinged to the fixed base 810, so the support leg 820 can rotate relative to the fixed base 810. Figure 1 and Figure 4 As shown, when adjusting the deflection angle of the bulldozer blade 600, the support leg 820 is turned counterclockwise so that the lower end of the support leg 820 touches the ground, and the latch 831 is engaged in the limiting groove under the spring force of the second compression spring 840 to provide stable support.

[0048] Then, the transplanting worker presses down on the handwheel 300 to disengage the tenon 101 from the groove 701, and rotates the handwheel 300 to adjust the deflection angle of the bulldozer blade 600; subsequently, the transplanting worker releases the handwheel 300, and under the spring force of the first compression spring 210, the tenon 101 re-inserts into the groove 701, thus locking the deflection angle of the bulldozer blade 600 (e.g., Figure 2 and Figure 3 As shown in the figure, the transplanting worker finally turned the support leg 820 clockwise so that it no longer supported the ground.

[0049] The soil excavated by the small excavator is usually piled around the planting pit. After the poplar sapling is placed in the planting pit, the transplanting workers operate the hand-held tractor 500 to drive around the sapling with the sapling as the center. With the push of the bulldozer 600, most of the soil around the planting pit is filled into the planting pit. Since the soil ball of the poplar sapling occupies part of the space in the planting pit, a small part of the soil will remain and cannot be backfilled into the planting pit.

[0050] After the current planting pit is filled, the transplanting workers continue the above process for the next planting pit. Another worker uses a shovel to build a embankment around the current planting pit with the remaining soil, while tamping down the soil inside the planting pit to keep it higher on the outside and lower on the inside, so that the planting pit can be watered. This process is repeated to achieve efficient cultivation of poplar trees, while also greatly reducing the labor intensity of the workers.

[0051] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
