DETAILED DESCRIPTION

[0016] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, but not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0017] like Figure 1-3As shown in the figure, it includes a hood 13, an auger 18 is provided on the inner side of the hood 13, the connecting hole 12 at the upper end of the hood 13 is connected to the snow outlet 3, the upper end of the snow outlet 3 is connected to the snow guard 1, and an engine 2 is also provided on the hood 13. One side of the hood 13 is also provided with a transmission mechanism connected to the engine 2 and the auger 18, the transmission mechanism includes a centrifugal clutch 10, a driven wheel 11, a V-belt 8, a tensioning wheel 19, an adjusting rod 15 and an adjusting spring 16. The rear end of the hood 13 is also provided with a suspension mechanism connecting the whole to the tractor, and the suspension mechanism includes a swing suspension bracket 4 and a lower suspension bracket 7. Engine 2 rotates at high speed, driving auger 18 through a transmission mechanism to spin at high speed, throwing snow out of the snow outlet, completing the operation. The left and right auger blades of auger 18 squeeze the snow in the middle, and the snow thrower moves at high speed to throw the snow out of the snow outlet. The driving force comes from engine 2, and the auger speed is very high, reaching 1200 r / min. The overall performance is stable and reliable, and the machine can be used for a long time, replacing manual cleaning and greatly reducing labor usage. The swing suspension bracket 4 on the suspension mechanism is fixedly connected to the tractor's front mounting plate. The oil pipe assembly is connected to the two connectors of the tractor. When the tractor is started, hydraulic oil is input to the oil cylinder. The oil cylinder is adjusted to extend and retract, allowing the two slides on both sides of the snowblower to be close to the ground, thereby widening the cleaning area, improving efficiency, and providing strong processing capabilities and multi-angle cleaning.

[0018] The specific structure of the suspension mechanism is as follows: the lower suspension bracket 7 is arranged in parallel, with one end connected to the lower end of the swing suspension bracket 4 via a rotating shaft, and the other end connected to the connecting beam at the rear end of the hood 13. The swing suspension bracket 4 is connected to the other connecting beam at the rear end of the hood 13 via the snowblower cylinder 6, which is arranged at an angle. The snowblower cylinder 6 is connected to the oil pipe 5, which is connected to two connectors on the tractor. When the tractor is started, hydraulic oil is input into the snowblower cylinder 6, and the cylinder is adjusted to extend and retract to keep the two slides of the snowblower close to the ground.

[0019] The transmission mechanism's specific structure is as follows: a centrifugal clutch 10 is connected to the output shaft of the engine 2; a driven pulley 11 is connected to the shaft end of the auger 18 via a tensioning sleeve 20; a V-belt 8 is mounted on the centrifugal clutch 10 and the driven pulley 11, respectively; an expansion pulley 19 and an adjustment rod 15 are mounted on a tensioning pulley bracket 14; an adjustment spring 16 is mounted on the adjustment rod 15; and the tensioning pulley bracket 14 is mounted on a side panel on one side of the hood 13. Adjusting the tension of the adjustment spring 16 drives the lateral swing of the expansion pulley 19, thereby controlling the tension of the V-belt 8.

[0020] The side plate on hood 13 sides is also provided with a housing base plate 17 and a housing cover plate 9 for protecting the transmission mechanism, and the housing cover plate 9 is fixed on the housing base plate 17.
