Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically to a low-resistance ice-breaking transmission box and a snowplow. Background Technology

[0002] Snowplows primarily use high-speed rotating agitator blades to break up snow, thus achieving snow removal. The agitator blades are typically mounted on a rotating shaft inside the agitator housing. However, in current snowplow technology, the power unit and the rotating shaft are connected via a transmission mechanism. This transmission mechanism is generally a worm gear structure, and to protect the worm gear, a transmission box is usually designed inside the agitator housing to house it.

[0003] Because the transmission box is installed inside the auger shell, when the snowplow moves forward, the transmission box will directly impact and squeeze the snow and ice in front of it. Therefore, the transmission box experiences greater resistance, and the snow and ice will also impact the transmission box, which can easily cause damage to the transmission box. Utility Model Content

[0032] like Figure 1-6 As shown, in one embodiment of this utility model, a low-resistance ice-breaking transmission box and a snowplow equipped with the aforementioned low-resistance ice-breaking transmission box are provided. The low-resistance ice-breaking transmission box includes a box body 100, and the box body 100 is provided with a first blade 101, a second blade 102, and a third blade 103 connected in sequence. The first blade 101 is located on the front side of the box body 100, and the second blade 102 is located below the first blade 101, with one end of the second blade 102 inclined towards the rear side of the box body 100 away from the first blade 101. The third blade 103 extends towards the rear side of the box body 100 and is inclined upwards at one end away from the second blade 102.

[0033] The housing 100 is provided with a first mounting hole 1011 and a second mounting hole 1012. The first mounting hole 1011 is located on the rear side of the housing 100, and the worm gear 200 is mounted on the housing 100 through the first mounting hole 1011. The second mounting hole 1012 penetrates the housing 100, and the axes of the first mounting hole 1011 and the second mounting hole 1012 are perpendicular to each other in space. The output shaft 300 is mounted on the housing 100 through the second mounting hole 1012, and the agitator blades are mounted on the output shaft 300. A worm wheel (not shown in the attached figure) that mates with the worm gear 200 is fixedly sleeved on the output shaft 300. The worm wheel is located in the inner cavity of the housing 100, and the rotation of the output shaft 300 can be realized through the meshing transmission between the worm gear 200 and the worm wheel.

[0034] This embodiment discloses a low-resistance ice-breaking transmission box and snowplow. By designing a first blade 101, a second blade 102, and a third blade 103 on the box body 100, during forward movement, these blades effectively break up ice, thereby reducing the resistance experienced by the box body 100, minimizing the impact of ice on the box body 100, and improving the protective effect on the box body 100. Simultaneously, the connection between the second blade 102 and the third blade 103 forms a "V"-shaped corner, which facilitates cutting the ice, thus improving the breaking effect. Furthermore, the third blade 103 is inclined upwards, allowing it to move close to the ice broken by the second blade 102, further reducing the resistance experienced by the box body 100 from the broken ice.

[0035] In one embodiment, the low-resistance ice-breaking transmission box further includes a fourth blade 104 and a fifth blade 105. The fourth blade 104 is connected to the end of the first blade 101 away from the second blade 102, and the end of the fourth blade 104 away from the first blade 101 is inclined toward the rear side of the box body 100. The fifth blade 105 is located at the top of the box body 100, and the fifth blade 105 is connected to the end of the fourth blade 104 away from the first blade 101.

[0036] Since the fourth blade 104 and the second blade 102 are located above and below the first blade 101, respectively, close to the top and bottom of the housing 100, the front side of the housing 100 is fully surrounded by the blades, thus further enhancing the ice-breaking effect. The design of the fifth blade 105 increases the continuity of the ice-breaking effect of the fourth blade 104 and also protects the top of the housing 100, reducing the resistance encountered by the top of the housing 100 as it moves forward.

[0037] In one embodiment, the edge of the fifth blade 105 gradually slopes toward the top of the box 100. While ensuring the ice-breaking effect, the fifth blade 105 does not need to extend excessively toward the rear of the box 100. In this way, the length of the fifth blade 105 will not be designed to be too long, thereby reducing the use of materials and lowering manufacturing costs.

[0038] In one embodiment, the two side walls of the box 100 are respectively recessed to form first grooves 106. The first grooves 106 are close to the top of the box 100 and extend towards the rear of the box 100. As the box 100 moves forward, it will distribute broken ice blocks to both sides of the box 100. Therefore, the design of the first grooves 106 can give way to the broken ice blocks to a certain extent, thereby reducing the resistance experienced by the box 100.

[0039] In one embodiment, the two side walls of the housing 100 are respectively recessed to form a second groove 107, and the second groove 107 is close to the end of the third blade 103. The design principle of the second groove 107 is similar to that of the first groove 106, and will not be described again in this embodiment.

[0040] In one embodiment, the housing 100 includes two interlocking shells 108, which are fastened together by multiple bolts. Each shell 108 has a cutting edge 109, which connects to form a first cutting edge 101, a second cutting edge 102, and a third cutting edge 103. By designing the housing 100 as a split structure, it is easier to design and manufacture individual shells 108, thereby reducing the difficulty of molding the overall structure.

[0041] Furthermore, existing transmission cases typically consist of a transmission case housing and a rear cover, with the rear cover mounted on the rear side of the housing; that is, existing transmission cases employ a front-to-rear split structure. However, this design requires flange bosses on both the transmission case housing and the rear cover to achieve a secure connection. These flange bosses increase the space occupied by the transmission case on both sides, thereby increasing the resistance experienced by the transmission case during operation.

[0042] In this embodiment, the box 100 is composed of two interlocking shells 108. Therefore, the outer side wall of the box 100 does not need to be designed with a flange boss structure for assembly. As a result, the box 100 occupies less space in the left and right directions, which can further reduce the resistance encountered by the box 100 during movement.

[0043] In one embodiment, a sealing gasket 1010 is provided between the two housings 108 to improve the sealing performance of the inner cavity of the housing 100.

[0044] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
