Description

TECHNICAL FIELD

[0001] The utility model belongs to snow sweeping equipment technical field relates to a snow sweeper snow outlet tube's mounting mechanism. BACKGROUND

[0002] Because in high latitude area, the snowfall is larger in winter, easily leads to road snow accumulation, causes traffic jam, influences people's travel, therefore needs to clean up the accumulated snow. And the snow sweeper as a kind of professional snow sweeping equipment, due to its high cleaning efficiency, flexible use and convenient operation, is widely used in various scenes of snow removal operation.

[0003] The working principle of snow sweeper is mainly through spiral blade to cut and suck snow into auger box, then utilize the rotating impeller to throw the cut snow block to the roadside by centrifugal action. Such as the snow sweeper auger box assembly disclosed in Chinese patent application (application number: 202411744738.9), shell, spiral auger one and multiple spiral auger two arranged on the inner side of shell, rear cover arranged on the rear surface of shell, snow outlet tube arranged on the surface of rear cover and communicated with the inside of rear cover, snow throwing guide plate arranged on the top of snow outlet tube, make snow enter the shell by two spiral augers cooperation suction, and enter the rear cover, then throw to one side by snow outlet tube and snow throwing guide plate. Among them, the connecting structure between the existing snow outlet tube and rear cover is relatively simple, only through several screws arranged circumferentially around the snow outlet tube and connected with the rear cover, such as the snow throwing tube mounting structure of snow sweeper disclosed in Chinese patent application (application number: 201921927484.9) adopts the structure. However, since the direction of snow entering the snow outlet tube from the rear cover is basically the same as the axial direction of the screw, i.e. the impact direction of snow on the snow outlet tube is basically the same as the axial direction of the screw, which causes the snow outlet tube to vibrate along the axial direction of the screw during long-term use, which easily causes the screw to loosen or even fall off, thereby affecting the use. Moreover, since part of the bolt is located on the inside of the snow outlet tube and is in the same direction as the snow outlet tube, the installation space of the bolt is small, and the installation is extremely inconvenient. SUMMARY

[0004] The utility model aims at the above-mentioned problems existing in prior art, proposes a snow sweeper snow outlet tube mounting structure, and the technical problem to be solved by the utility model is how to make the snow outlet tube more easily installed and more stable after installation.

[0005] The objective of this utility model can be achieved through the following technical solution: A snowplow snow discharge tube installation structure, comprising a rear cover and a snow discharge tube, wherein one end of the rear cover has an opening and the other end has an end face, and a snow discharge port is opened on the side wall of the rear cover, characterized in that one end of the snow discharge tube has a first mounting surface for fitting against the side wall of the snow discharge port of the rear cover, one side of the first mounting surface has a positioning groove for the edge of the snow discharge port to be embedded, and the other side of the first mounting surface opposite to the positioning groove has a second mounting surface for fitting against the end face of the rear cover, and a plurality of first mounting holes for screws to pass through are opened on the second mounting surface.

[0006] During installation, the positioning slot of the snow outlet tube is first engaged with the edge of the snow outlet near the opening on the rear cover. Then, the first mounting surface is aligned with the side wall of the snow outlet on the rear cover, and the second mounting surface is aligned with the end face of the rear cover away from the opening. Finally, a screw is threaded through the mounting hole and connected to the rear cover, thus installing the snow outlet tube onto the rear cover. Because the snow outlet tube is first positioned by engaging the positioning slot with the edge of the snow outlet before tightening the screw, misalignment between the snow outlet tube and the rear cover is avoided. Since the impact of snow on the snow outlet tube is radially perpendicular to the screw's axis, the impact of snow on the snow outlet tube is less likely to loosen the screw, resulting in a more stable installation. Furthermore, the screws of this invention are mounted on the end face of the rear cover, providing a relatively open installation position and avoiding interference with other components. Disassembly and assembly are simpler and more convenient, and even if the screws become loose, they are easier to see and tighten.

[0007] In the above-mentioned snowplow snow discharge cylinder installation structure, the snow discharge cylinder includes a straight section and an installation part. The straight section has a snow discharge channel for communicating with the inner cavity of the rear cover. The installation part includes the above-mentioned first installation surface and second installation surface. The first installation surface is arranged around the inlet of the snow discharge channel, and the snow discharge channel is arranged along the tangential direction of the rear cover.

[0008] In the above-described snowplow snow discharge tube installation structure, the mounting holes are spaced apart along the length of the second mounting surface.

[0009] In the above-mentioned snowplow snow discharge tube installation structure, the inner side of the first mounting surface away from the second mounting surface has an L-shaped support part. The support part is arranged along the length direction of the edge of the second mounting surface and forms the positioning groove between it and the first mounting surface. The length of the support part is less than the edge length of the snow outlet and the positioning groove, so that the support part extends into the snow outlet and forms a fit with the edge of the snow outlet.

[0010] In the above-mentioned snowplow snow discharge tube installation structure, the upper edge of the inlet of the snow discharge channel has an outwardly protruding baffle, which is embedded in the snow outlet of the rear cover.

[0011] In the above-described snowplow snow discharge tube installation structure, the first mounting surface is a concave arc shape, and the outer side of the support part has a baffle opposite to the second mounting surface. The baffle not only improves the structural strength of the support part and the positioning slot, but also forms a funnel shape with the first mounting surface and the end face of the rear cover, so that snow blocks can enter the snow discharge channel from the rear cover.

[0012] In the above-described snowplow snow discharge tube installation structure, the first mounting surface and the second mounting surface are perpendicular to each other.

[0013] In the aforementioned snowplow snow discharge cylinder installation structure, the side wall of the rear cover includes an arc surface and an irregularly shaped surface. The arc surface is arc-shaped, and the irregularly shaped surface protrudes outward relative to the arc surface. The snow outlet is located on the irregularly shaped surface. The outwardly protruding irregular structure of the side wall at the snow outlet of the rear cover increases the space at the snow outlet, facilitating the entry of snow blocks into the snow discharge cylinder and preventing snow blocks from being pushed back into the rear cover by the impeller due to delayed snow discharge. Furthermore, while ensuring snow discharge efficiency, it also allows for a smaller opening in the circumferential direction of the snow outlet, resulting in higher structural strength for the rear cover.

[0014] In the above-mentioned snowplow snow discharge tube installation structure, the outer circumferential surface of the straight section has several reinforcing ribs and reinforcing bars. The reinforcing bars are arranged in a ring along the circumference of the straight section and are distributed at intervals along the axial direction of the straight section. The reinforcing ribs are distributed at intervals along the circumference of the straight section, and the reinforcing ribs are arranged along the axial direction of the straight section and are connected to the reinforcing bars at intersections.

[0015] In the snowplow installation structure described above, the angle of the snow outlet along the circumferential side wall of the rear cover is less than 90°.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model provides positioning slots and second mounting surfaces on both sides of the first mounting surface at one end of the snow outlet. During installation, the positioning slots are first engaged with the edge of the snow outlet side of the snow outlet to ensure a stable fit between the snow outlet and the rear cover. Then, screws are passed through the mounting holes on the second mounting surface and connected to the end face of the snow outlet for fixation. The installation operation is simple and quick. Furthermore, because the axis of the screw is perpendicular to the direction of impact of the snow on the snow outlet, the screw is less prone to loosening, making the connection between the snow outlet and the rear cover more secure.

[0018] 2. Since the screws are installed on the end face of the rear cover, and there are no external objects interfering with one side of the end face of the rear cover, and it is located on the outside, the operating space for screw installation is larger, making it easier to install, and it is also easier to observe whether the screws are loose, which facilitates later maintenance.

[0019] 3. The side wall of the snow outlet on the rear cover adopts an outward protruding irregular surface, which can not only increase the space in this area and improve the snow discharge efficiency, but also make the snow outlet shorter in the circumferential direction while ensuring snow discharge efficiency, thereby improving the structural strength of the rear cover.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figs. 1-3 As shown, an installation structure for a snowplow's snow discharge tube is disclosed. This utility model is applied to a snowplow auger box assembly, which includes a housing 11 and two spiral augers 12. The two spiral augers 12 are rotatably connected to the opening of the housing 11, and the two spiral augers 12 rotate in opposite directions, so that the two spiral augers 12 can cooperate to cut snow into small pieces and suck them into the housing 11. The installation structure for the snowplow's snow discharge tube includes a rear cover 2 and a snow discharge tube 3. The rear cover 2 is connected to the rear side of the housing 11, and an impeller is rotatably installed inside the rear cover 2. The snow discharge tube 3 is connected to one side of the rear cover 2 and communicates with the inner cavity of the rear cover 2. The outer end of the snow discharge tube 3 is used to connect to a snow throwing guide plate, so that after the snow blocks pass through the housing 11 and enter the rear cover 2, they are sprayed out along the snow discharge tube 3 under the centrifugal action of the impeller.

[0029] Specifically, such as Figs. 3-6 As shown, one end of the rear cover 2 has an opening and the other end has an end face. The edge of the rear cover 2 with the opening has a mounting flange 22 arranged circumferentially for fixing the rear cover 2 to the housing 11. A snow outlet 21 is opened on the side wall of the rear cover 2, and the snow outlet tube 3 is connected to the rear cover 2 at the snow outlet 21. The snow discharge tube 3 includes a straight section 31 and a mounting part 32. The straight section 31 is a hollow cylinder, and its inner cavity is a snow discharge channel 3a for communicating with the inner cavity of the rear cover 2. In this embodiment, the snow discharge channel 3a is arranged along the tangential direction of the rear cover 2, so that snow blocks enter the snow discharge channel 3a more smoothly and reduce the impact on the snow discharge tube 3. The upper end of the straight section 31 is used to connect the snow throwing guide plate. The mounting part 32 is located at the lower end of the straight section 31 and includes a first mounting surface 321 and a second mounting surface 322 integrally connected. The first mounting surface 321 is arranged around the inlet of the snow discharge channel 3a and can be tightly fitted with the side wall at the snow outlet 21 of the rear cover 2. A positioning groove 32a with an outward opening is provided on one side of the first mounting surface 321. The positioning groove 32a is provided along the edge of the first mounting surface 321. The second mounting surface 322 is located on the other side opposite to the positioning groove 32a of the first mounting surface 321. The second mounting surface 322 is provided along the edge of the first mounting surface 321, and a plurality of mounting holes 322a for mounting screws are opened on the second mounting surface 322. The mounting holes 322a are spaced apart along the length direction of the second mounting surface 322. In this embodiment, the first mounting surface 321 and the second mounting surface 322 are basically perpendicular to each other, so that the axial direction of the screw is basically perpendicular to the direction in which the snow block enters the snow outlet channel 3a, thereby making the screw less likely to loosen.

[0030] During installation, simply fit the positioning slot 32a on the snow outlet 3 with the edge of the snow outlet 21 near the mounting flange 22 to ensure a stable fit between the snow outlet 3 and the rear cover 2. Then, fit the first mounting surface 321 against the side wall of the rear cover 2 and the second mounting surface 322 against the end face of the rear cover 2 away from the opening. Finally, pass a screw through the mounting hole 322a on the second mounting surface 322 and thread it onto the end face of the rear cover to fix the snow outlet 3 on the rear cover 2 and connect the snow outlet channel 3a with the inner cavity of the rear cover 2.

[0031] like Fig. 6As shown, in this embodiment, the first mounting surface 321 is a concave arc shape. An L-shaped support portion 323 is located on the inner side of the first mounting surface 321 away from the second mounting surface 322. The support portion 323 is arranged along the length of the edge of the second mounting surface 322, forming the aforementioned positioning groove 32a between the support portion 323 and the first mounting surface 321. The length of the support portion 323 is less than the length of the edge of the snow outlet 21 that mates with the positioning groove 32a, allowing the support portion 323 to extend into the snow outlet 21 and the positioning groove 32a to fit into the edge of the snow outlet 21. Furthermore, when the snow tube 3 is installed on the rear cover 2, the screws on the support portion 323 and the second mounting surface 322 respectively limit the first mounting surface 321 from both sides, ensuring a tight fit between the first mounting surface 321 and the side wall of the rear cover 2, guaranteeing a seal.

[0032] like Fig. 4 , Fig. 6 As shown, the outer side of the support 323 has a baffle 324. The baffle 324 extends from one end of the support 323 to the other end of the support 323 and is opposite to the second mounting surface 322. This improves the structural strength of the positioning slot 32a and makes the first mounting surface 321, the baffle 324 and the end face of the rear cover 2 that is in contact with the second mounting surface 322 form a funnel shape that communicates with the snow outlet channel 3a, so that the snow blocks in the rear cover 2 can enter the snow outlet channel 3a.

[0033] like Fig. 5 As shown, the sidewall of the rear cover 2 adopts an irregular structure design, including an arc surface 2a and an irregular surface 2b connected end to end. The arc surface 2a is arc-shaped, and the irregular surface 2b protrudes outward relative to the arc surface 2a. The snow outlet 21 is opened on the irregular surface 2b, making the internal cavity of the rear cover 2 larger at the irregular surface 2b, which facilitates the impeller to push snow blocks into the snow outlet tube 3 from this point, improving snow discharge efficiency. In this embodiment, the irregular surface 2b is approximately right-angled, and the snow outlet 21 is opened along the circumferential direction of the sidewall of the rear cover 2. The angle of the snow outlet 21 along the circumferential direction of the sidewall of the rear cover 2 is greater than 70° and less than 90°, which ensures both snow discharge efficiency and structural strength of the rear cover 2.

[0034] Furthermore, in this embodiment, the upper edge of the inlet of the snow outlet channel 3a has an outwardly protruding retaining edge 325. The retaining edge 325 is located between the second mounting surface 322 and the support portion 323. When the snow outlet tube 3 is installed on the rear cover 2, the retaining edge 325 can be embedded in the snow outlet 21 of the rear cover 2, thereby improving the fitting accuracy and sealing performance of the snow outlet channel 3a and the snow outlet 21.

[0035] Furthermore, a number of reinforcing ribs 33 and reinforcing ribs 34 are provided on the outer circumferential surface of the straight section 31 of the snow outlet 3. The reinforcing ribs 33 are arranged in a ring along the circumference of the straight section 31 and are distributed at intervals along the circumference of the straight section 31. The reinforcing ribs 34 are in the shape of long strips and are arranged along the axial direction of the straight section 31 and are distributed at intervals along the circumference of the straight section 31. The reinforcing ribs 34 and the reinforcing ribs 33 are intersected and connected to form a grid structure, thereby greatly improving the structural strength of the straight section 31.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0037] Although this document frequently uses terms such as shell 11, auger 12, rear cover 2, and snow outlet 3, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
