[0002] China has had a tradition of planting trees since ancient times, and many interesting stories and anecdotes advocating afforestation have emerged. The best time to plant trees is the Qingming Festival, when the climate is warm and the spring rain is flying, which is conducive to the survival of seedlings. Planting trees is of great significance for regulating the climate, conserving water resources, and reducing air pollution. The specific steps of planting trees are digging holes, backfilling, planting, and covering with soil to conserve moisture.

[0003] The patent with the patent authorization announcement number CN205999959U discloses a pit digger, which drives the inner rod of the telescopic rod to slide inside the outer rod through a hydraulic cylinder, and controls the angle of the gearbox through a universal shaft and a telescopic bracket, and drives the spiral drill bit through the gearbox to drill and dig a pit, and the pit dug has a high verticality. However, the pit digger provided by the patent still has shortcomings in actual use. Since the spiral drill bit is connected to the gearbox, the drill bit cannot be replaced, and the size of the soil pit drilled is fixed. If the tree is larger than the pit, it cannot be planted. If the tree is much smaller than the pit, it is more troublesome to backfill.

[0004] Therefore, it is necessary to provide a tree planting pit digging machine capable of replacing the drill bit. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0025] Embodiment 1: A tree planting and digging machine, see Figure 1 and Figure 2 As shown, it includes a mounting plate 1, a universal wheel 2, a push rod 3, a support block 4, a guide rod 5, an elastic member 501, a fixed block 6, a fixed frame 7 and a motor 8. Four universal wheels 2 are installed at the four corners of the bottom of the mounting plate 1 by bolt connection. A push rod 3 is installed on the mounting plate 1 by bolt connection. A support block 4 is installed on the middle part of the mounting plate 1 by bolt connection. The guide rod 5 is fixedly connected to the support block 4 by welding. A fixed block 6 is slidably arranged on the guide rod 5. The fixed block 6 slides up and down along the guide rod 5. An elastic member 501 for pushing the fixed block 6 to slide upward and reset is arranged on the guide rod 5. A fixed frame 7 is installed on the fixed block 6 by welding. A motor 8 is installed on the fixed frame 7 by bolt connection. The output shaft of the motor 8 faces downward. The output shaft of the motor 8 is fixedly connected to a transmission rod 9 by a coupling. A replaceable earth drill bit 10 is installed at the bottom of the transmission rod 9 by key connection. The earth drill bit 10 is key-connected to an iron drill bit 11 by a connecting column 12.

[0026] It also includes a scale mark 14 arranged on the transmission rod 9 , a fixing plate 13 is installed on the mounting plate 1 , the transmission rod 9 penetrates the fixing plate 13 , and the fixing plate 13 corresponds to the scale mark 14 .

[0027] When it is necessary to dig a hole on a relatively hard geological surface, the connecting column 12 of the iron drill bit 11 is inserted into the bottom of the earth drill bit 10. When the earth drill bit 10 rotates to dig a hole, the iron drill bit 11 will first contact the ground and break the hard geological surface to assist in digging a hole. Subsequently, the transmission rod 9 is driven to rotate by starting the motor 8, and the transmission rod 9 drives the earth drill bit 10 to rotate, and the fixed block 6 drives the fixed frame 7 and the motor 8 to slide downward along the guide rod 5. At this time, the elastic member 501 is compressed and deformed by the force, and the hole is dug by the earth drill bit 10. After the hole is dug, the fixed frame 7 is released. At this time, the elastic member 501 loses the force and returns to its original state, thereby pushing the fixed block 6 to slide upward along the guide rod 5 to reset, so that the guide rod 5 and the earth drill bit 10 withdraw from the earth pit; when it is necessary to control the size of the hole, the earth drill bit 10 can be removed from the transmission rod 9, the earth drill bit 10 of the required size can be replaced, the new earth drill bit 10 is keyed into the transmission rod 9, and the above-mentioned hole digging operation can be performed.

[0028] When the fixed frame 7 drives the motor 8 to move downward, the transmission rod 9 will drive the earth drill bit 10 to move downward. The corresponding scale mark 14 on the transmission rod 9 indicated by the fixed plate 13 can accurately measure the digging depth, avoid unnecessary excessive digging, save working time, and improve digging efficiency.

[0029] See also Figure 5 As shown, it also includes two storage boxes 15 for storing fertilizers installed on the mounting plate 1 by bolt connection. A glass plate is embedded on the side of the storage box 15 to facilitate observation of the remaining fertilizer in the storage box 15 so as to replenish the fertilizer in time. A cover plate 17 is rotatably provided on the top of the storage box 15. The storage box 15 is connected to the mounting plate 1 and is connected to a feed pipe 16. The feed pipe 16 is provided with an external thread to facilitate threaded connection to a conduit to guide the fertilizer to the desired fertilization position.

[0030] By flipping open the cover plate 17, fertilizer or water can be added to the storage box 15. After drilling and digging, the water or fertilizer in the storage box 15 can fall into the earth pit through the feed pipe 16, and there is no need for subsequent watering and fertilization.

[0031] See also Figure 1 As shown, both sides of the fixing frame 7 are installed with pressure rods 18 by bolt connection, and the mounting plate 1 is installed with a fixing frame 19 for placing the battery for powering the motor 8 by bolt connection. When the fixing frame 7 needs to be moved downward, the fixing frame 7 can be pressed down more easily by holding the pressure rods 18, and the fixing frame 19 can place the battery. When the battery runs out of power, the battery can be quickly replaced and placed in the fixing frame 19 to prevent the battery from being placed flat on the mounting plate 1 and falling to the ground and being damaged.

[0032] See also Figure 1 , Figure 2As shown, a plurality of universal wheels 2 are installed at the bottom of the mounting plate 1, and a push rod 3 is installed on the mounting plate 1. When digging a pit is required, the push rod 3 and the universal wheel 2 are used to move the device to the required position for subsequent operations, which is flexible and convenient to use.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
