Description

Technical Field

[0001] The utility model relates to the technical field of forestry disease prevention and control, in particular to a portable crusher. Background Art

[0002] Pine wilt disease, also known as pine wilt disease, is a devastating disease caused by pine nematodes parasitizing pine trees, causing rapid death of trees. It is one of the four major forest diseases in the world today and is known as the "cancer" of pine trees. Pine wilt disease is the most dangerous and destructive forest disease in the global forest ecosystem. It is highly contagious and destructive and is listed as a quarantine pest by more than 50 countries around the world.

[0003] Pine wood nematode disease has the characteristics of multiple transmission routes, hidden disease sites, rapid onset, long incubation period, and great difficulty in control. The main prevention and control measures include: quarantine, chemical control, cleaning of diseased and dead wood, and forestry prevention and control.

[0004] The methods for treating pine wood nematode diseased wood mainly include the following:

[0005] (1) Crushing treatment: Applicable to areas where pine wood nematode disease occurs, use a crusher to crush or chip the infected wood, with the particle size of the crushed material not exceeding 1 cm and the thickness of the chips not exceeding 0.5 cm.

[0006] (2) Burning treatment. This method is applicable to areas where the number of trees infected with pine wilt disease is small and there is no condition for crushing or chipping. The infected trees should be cut into 1 to 3 meters long and all branches larger than 1 cm should be burned.

[0007] The choice of the above methods should be determined based on the specific circumstances of the epidemic and the actual local conditions to ensure that the spread of the epidemic can be effectively controlled while protecting environmental safety.

[0008] At present, in order to prevent fires in forest areas, pine wood nematode-infected trees and branches with a diameter of 1 cm or more are generally carried down the mountain by hand and crushed by large crushers. As for branches with a diameter of less than 1 cm, there are many of them and they are large in size. It is inconvenient to bundle and carry them down the mountain manually. The most convenient solution is to crush them on the spot. However, traditional crushers are large in size and heavy in weight, making them inconvenient to carry on mountain roads and dense forests.

[0034] like Figure 1-Figure 3As shown, the utility model provides a portable crusher for crushing branches with a diameter of less than 1 cm on site. The portable crusher includes a crushing box 1, a crushing mechanism arranged in the crushing box 1, and a crushing power mechanism detachably arranged on the top of the crushing box 1. The crushing power mechanism is connected to the crushing mechanism in a transmission manner, and is used to drive the crushing mechanism to crush the pine wood nematode diseased wood in the crushing box 1. A roller 2 for pushing is arranged at the bottom of the crushing box 1, and a push handle 4 is arranged on the side of the crushing box 1 opposite to the feed hopper 3, and the crushing box 1 can be pushed to move by the push handle 4. A feed hopper 3 is detachably arranged on one side of the crushing box 1, and a discharge port is arranged at the bottom of the crushing box 1. Pine branches infected with pine wood nematode disease are put into the crushing box 1 from the feed hopper 3, crushed by the crushing mechanism, and the crushed particles are discharged from the discharge port.

[0035] In this embodiment, the crushing power mechanism includes a gasoline engine 5. A fixing frame 6 is fixedly mounted on the top of the crushing box 1, and the gasoline engine 5 is detachably mounted on the fixing frame 6 by bolts. The gasoline engine 5 is used to drive the crushing mechanism, which is suitable for use in wild forest areas.

[0036] In this embodiment, the crushing mechanism includes two crushing rods 7 arranged side by side, and the crushing teeth of the two crushing rods 7 are arranged in a staggered manner, which is conducive to finer crushing. The two ends of the crushing rods 7 are rotatably mounted on the inner wall of the crushing box 1 through the bearing seat 8, and one end of one crushing rod 7 is transmission-connected to the gasoline engine 5, and the other end is transmission-connected to the end of the other crushing rod 7 through the gear 9. When the gasoline engine 5 drives one of the crushing rods 7 to rotate, the gear 9 synchronously drives the other crushing rod 7 to rotate in the opposite direction, so that the crushing speed is faster and the efficiency is higher.

[0037] Specifically, a synchronous wheel 10 is provided at one end of one of the crushing rollers 7, and the synchronous wheel 10 is drivingly connected to the output shaft of the gasoline engine 5 through a synchronous belt.

[0038] The feed hopper 3 is tilted upward, and a connecting plate 11 is provided at the bottom of the feed hopper 3. The connecting plate 11 is fixedly mounted on the side wall of the crushing box 1 by bolts. After removing the bolts, the feed hopper 3 can be removed from the crushing box 1 for disassembly.

[0039] The crushing box 1 has mounting seats 12 on both sides of the bottom, and two rollers 2 are provided. The two rollers 2 are connected by a wheel axle 13, and the wheel axle 13 is rotatably installed in the two mounting seats 12 through a bearing. A support stand 14 is provided at one end of the push handle 4 away from the crushing box 1. When the crushing operation is performed, the support stand 14 is supported on the ground to keep the crushing box 1 stable. The support stand 14 is an inverted T-shaped structure, and an anti-skid pad is provided at the bottom of the support stand 14. The anti-skid pad can be a rubber pad to increase the friction resistance with the ground, so that the crushing box 1 can remain stable.

[0040] In summary, the portable crusher provided by the utility model is used to crush branches with a diameter of less than 1 cm on the spot. The portable crusher adopts a modular design. When carrying and transporting, the crushing power mechanism, the feed hopper and the crushing box can be disassembled and carried separately. After the decomposition, each component is smaller in size and lighter in weight, which is more suitable for carrying and transporting in mountain roads and dense forests. The crushing box can be pushed, which is more labor-saving to carry. When the crushing operation is required, the components can be assembled on the spot.
