When the snow-collecting tube 100 needs to be inserted into a snow layer, two hands respectively hold the two pressure rods 170, and then apply force to the pressure rods 170. It should be understood that an anti-slip sleeve, which may be a rubber sleeve, may be provided on the pressurizing bar 170. The pressurizing rod 170 is screwed with the snow-collecting pipe 100, so that the snow-collecting pipe is convenient to disassemble and assemble, and is convenient to store and convey after being disassembled.
Optionally, the first side wall 130 is provided with a receiving hole 132 penetrating through the bottom wall of the first receiving groove 131 and communicating with the first receiving groove 131, and an end of the receiving hole 132 is located on an end surface of the first side wall 130 far away from the snow-collecting opening 110. The number of the receiving holes 132 is two, and the two receiving holes 132 are arranged at intervals on the second axis.
Referring to fig. 2-5, in the present embodiment, the cutter unit 210 optionally includes a cutter body 211 and a flexible layer 212. The blade body 211 is a rectangular blade body 211, and one length side of the blade body 211 is bonded or heat-sealed with a flexible layer 212. Guide rails 213 are respectively installed at two ends of the cutter body 211 in the length direction, the cross section of each guide rail 213 is square, the two guide rails 213 are respectively walked in the two slide ways 151, and the cross section of each slide way 151 is matched with the corresponding guide rail 213, so that the guide rails 213 cannot rotate relative to sliding when sliding in the slide ways 151, the cutter body 211 can cut snow layers in a horizontal state, and resistance in the cutting process is reduced. The flexible layer 212 may be a cloth layer or a rubber layer, the flexible layer 212 is a rectangular sheet, and the flexible layer 212 can be folded. When the initial state, that is, the cutter body 211 is at the second position, the flexible layer 212 is in the folded state and is located in the second receiving groove 141, the cutter body 211 may be located at the notch of the second receiving groove 141, and the cutter body 211 does not cover the snow-collecting opening 110. When the cutter body 211 is switched from the second position to the first position under the action of the driving member 220, the cutter body 211 can slide out of the notch of the second accommodating groove 141 and slide in the slideway 151 along the first axis extending direction toward the first accommodating groove 131, so as to drive the flexible layer 212 to move, the cutter body 211 cuts the snow layer and takes the flexible layer 212 out of the second accommodating groove 141 in the moving process, and the flexible layer 212 is unfolded and gradually blocks the snow collecting opening 110.
It will be appreciated that the length of the blade body 211 is no less than the size of the snow harvesting opening 110 in the second axis for improved cutting quality, for example portions of the blade body 211 may be located in the ramps 151 to ensure that the blade body 211 cuts through the snow layer when switching from the second position to the first position.
When the flexible layer 212 is a rubber layer, the flexible layer 212 has a certain elasticity and can return to deform when the external force is removed, so that the cutter body 211 can be driven to return to the second position from the first position.
Or, in other embodiments, the cutting assembly 200 further includes an elastic restoring member, the elastic restoring member is a spring, the elastic restoring member is connected to both the snow-collecting pipe 100 and the flexible layer 212, specifically, one end of the elastic restoring member is connected to the flexible layer 212, and the other end of the elastic restoring member is connected to the bottom wall of the second receiving groove 141, and the elastic restoring member is configured to enable the cutter body 211 to have a moving tendency of switching from the first position to the second position. In the snow-collecting process, when the driving member 220 drives the cutter body 211 to switch from the second position to the first position, the flexible layer 212 is driven by the cutter body 211 to close the snow-collecting opening 110, and the elastic reset member is driven by the flexible layer 212 to be in a stretching state, and after the external force applied to the driving member 220 is removed, the elastic reset member has elastic force for restoring deformation, so that the cutter body 211 is driven to automatically retract from the first position to the second position.
When the cutter body 211 is switched between the first position and the second position, in order to reduce the friction between the guide rail 213 and the slide 151, a roller may be disposed in the slide 151, the guide rail 213 is in contact with the roller, the roller can rotate in situ, and the cutter body 211 slides more flexibly relative to the snow hose 100.

It should be understood that the distance that the cutter body 211 is pulled can be controlled by the graduation lines on the cable, and when the cable is pulled, the length exposed outside the snow-collecting tube 100 is gradually increased, and when the set graduation appears, it indicates that the cutter body 211 is located at the first position, and at this time, the pulling is stopped. Or a limiting structure may be disposed in the accommodating grooves of the cutter body 211 and the first side wall 130, and when the cutter body 211 is pulled to a set position, the limiting structure limits the cutter body 211 to continue moving, so that the cable cannot continue to pull the cutter body 211 to move.
