Embodiment Construction

[0033] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0034] A tree stump crushing method: the tree stump can be crushed on the spot without digging out the tree stump. Prevent diseased trees from spreading along the way during transportation, so as to cut off the transmission route of pine nematodes and achieve the purpose of preventing and controlling pine nematodes.

[0035] The stump grinder is provided with a positioning plunger and a crushing mechanism; during work, the stump grinder positioning plunger is inserted into the soil near the stump, so that the crushing mechanism contacts one side of the stump, and then the crushing mechanism is controlled to work. crushed. This tree stump grinder is simple in structure and easy to operate.

[0036] The stump grinder comprises: a frame 1, a crushing mechanism arranged on the frame 1 and a positioning insert rod 5 arranged at the bottom of the fra...

Abstract

The invention provides a stump crushing method. According to the stump crushing method, under the condition that a stump does not need to be dug out, the stump is smashed on site, spreading is prevented through a diseased tree in the transportation process to cut off the spreading path of bursaphelenchus xylophilus, and the purpose of preventing and controlling the bursaphelenchus xylophilus is achieved. The invention also provides a stump crusher. The stump crusher comprises a rack, a power device, a transmission mechanism and a crushing mechanism, wherein the power device, the transmission mechanism and the crushing mechanism are installed on the rack, the crushing mechanism adopts a disposable hob, a staggered complementary arrangement mode is adopted for blades, stumps can be hobbed into bits smaller than 10 mm while a hobbing force is decreased, hobbing is stable, noise is low, and the hobbing efficiency is high.

Description

technical field [0001] The invention belongs to the field of forestry machinery, and in particular relates to a tree stump crushing method and a tree stump crushing machine. Background technique [0002] The pine nematode enters the xylem through the nutrient-supplemented wound of the monochamus, 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 nematodes are the targets of the monochamus for laying eggs. In the following year, the pine beetle will carry a large number of nematodes when it emerges, and inoculate them on "healthy trees", and this cycle will lead to the spread of pine nematodes. [0003] Cutting down diseased trees, cutting and crushing diseased trees on the spot are reliable countermeasures t...
