Embodiment 1

[0041] Example as Figure 1 to Figure 4 Shown: is a portable rotary drilling machine with an integral drill bit, including: a hand support 2, a power unit 1, a transmission rod 3 and an integral drill bit 4.

[0042] The hand frame 2 is a frame with a handle, and the frame of the hand frame 2 has bolt holes corresponding to the base of the power unit 1, and the power unit 1 is installed on the side of the hand frame 2 with a bolt assembly. on the frame.

[0043] The upper end of the transmission rod 3 is detachably connected to the output shaft of the power device 1 , and the lower end of the transmission rod 3 is detachably connected to the drill bit 4 . This detachable connection can disassemble the portable rotary drilling machine into parts that are easy to carry, so that it can be transported to complex forest areas, and the diseased tree shrubs can be crushed on the spot after reassembly.

[0044] The transmission rod 3 is a round tube, preferably a round tube with a w...

Embodiment 2

[0050] Example two such as Figure 5 Shown: the difference between embodiment two and embodiment one is: embodiment one adopts integral drill bit 4, and embodiment two adopts elongated blade rotary drill bit 6.

[0051] The strip-shaped blade rotary drill bit 6 includes: a drill base body 601, a detachable conical drill bit 602, a strip-shaped blade 603, a chip removal groove 604 and a connecting pipe 606. The central axis of the top of the drill base 601 is provided with the detachable conical drill 602, and on the side of the drill base 601, there are no less than two oblong blades 603 that are evenly distributed along the side. A chip removal groove 604 is arranged between the two sets of elongated blades 603, and a circular tube-shaped connecting pipe 606 is arranged on the central axis of the bottom surface of the drill base 601, and a radial pin is arranged on the connecting pipe 606. Hole 607. The diameter of the strip-shaped blade rotary drill bit is 200 mm, and the ...

Embodiment 3

[0055] Embodiment three such as Image 6 Shown: the difference between embodiment three and embodiment one is: embodiment one adopts integral drill bit 4, and embodiment three adopts blade group rotary drill bit 7.

[0056] The blade group rotary drill bit 7 includes: a drill base body 701, a drill bit 702, a guide blade 703, a main blade 704, and a connecting pipe 706. The drill base body 701 is in the shape of a truncated cone. The drill bit 702 is provided with no less than two guide blades 703 evenly distributed along the sides on the side of the top of the drill base 701, and a plurality of helical blades 703 are arranged on the side of the drill base 701 next to the guide blades 703. Arranged main blades 704, chip removal grooves 705 are arranged between two adjacent rows of main blades 704, and a connecting pipe 706 is arranged on the central axis of the bottom surface of the drill base 701, and a radial pipe 706 is arranged on the connecting pipe 706. Pin hole 707. T...

Abstract

The invention relates to a method for crushing tree stumps. Without having to dig out tree stumps, a portable rotary drilling machine is used to crush tree stumps in the soil on the spot, so as to prevent diseased trees from spreading along the way during transportation and to cut off pine tree stumps. The transmission route of nematodes can timely and effectively control the epidemic situation of pine nematodes and achieve the purpose of preventing and controlling pine nematodes. The rotary drilling machine adopted in the present invention is a portable rotary drilling machine, comprising: a hand support frame, a power unit, a transmission rod and a drill bit, the hand support frame is a frame with a handle, and the power unit is installed on the frame of the hand support frame, The output shaft of the power unit is detachably connected to the upper end of the transmission rod, and the lower end of the transmission rod is detachably connected to the drill bit, so as to facilitate entering the complex forest area to crush diseased tree stumps.

Description

technical field [0001] The invention belongs to the field of forestry machinery, and in particular relates to a stump crushing method. Background technique [0002] The pine xylophilus enters the xylem through the nutrient-supplemented wound of the pine woody beetle, and parasitizes in the resin canal. It moves while proliferating in large numbers, and gradually spreads throughout the whole plant, and causes the destruction and death of resin duct parenchyma cells and epithelial cells, causing the plant to lose water, and finally the whole plant dies. Pine trees infested with pine wood nematodes are the targets of pine beetles for laying eggs. The following year, when the monochamus alternatus emerges, it will carry a large number of nematodes and inoculate them on "healthy trees". This cycle will lead to the spread of pine wood nematodes. [0003] Forest clearing, cutting and burning of diseased and dying trees, and removal of diseased plant residues is a more reliable co...
