Technical Field

[0001] The utility model relates to the technical field of snow sweepers, in particular to a self-propelled system and a snow sweeper. Background Art

[0002] Single-step snowplows are primarily suitable for light snow and small snowy areas, resulting in a relatively compact design. They are generally available in two configurations: non-self-propelled and self-propelled. Existing self-propelled single-step snowplows typically utilize an additional power unit to drive the wheels, achieving self-propelled operation.

[0003] Since the single-step snow blower itself has a relatively compact structure, adding an additional power unit will inevitably take up extra space on the frame. Therefore, how to use the power of the engine to achieve the self-propelled function of the wheels in a small space is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a self-propelled system and a snowplow, which utilize the power of the power body to realize the power transmission in a narrow space to achieve the self-propelled function of the wheels.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a self-propelled system, including a frame, which is rotatably provided with a stirring basket shaft and two wheels; a power body, which is arranged on the frame, and the power body is provided with a first output shaft; a transmission assembly, which is transmission-connected to the first output shaft and the stirring basket shaft; a first transmission wheel, which is arranged on the first output shaft; a reducer, which is arranged on the frame and located below the first output shaft, and the reducer is provided with an input shaft and a second output shaft, and the second output shaft is transmission-connected to the two wheels, and the axes of the second output shaft, the first output shaft, the stirring basket shaft and the wheels are parallel; a second transmission wheel, which is arranged on the input shaft; and a first transmission belt, which is transmission-connected to the first transmission wheel and the second transmission wheel.

[0006] Preferably, the first transmission wheel and the second transmission wheel are connected in semi-cross transmission via the first transmission belt.

[0007] Preferably, the first transmission belt is a round belt.

[0008] Preferably, a rotating member is rotatably provided on the frame, the rotating member is located above the second transmission wheel, the rotation axis of the rotating member is parallel to the axis of the second transmission wheel, and the first transmission belt abuts against the outer side wall of the rotating member.

[0009] Preferably, the transmission assembly includes a third transmission wheel, a fourth transmission wheel and a second transmission belt, the third transmission wheel is arranged on the first output shaft, the fourth transmission wheel is arranged on the stirring cage shaft, and the second transmission belt transmission connects the third transmission wheel and the fourth transmission wheel; the first transmission wheel is located between the power body and the third transmission wheel, and the reducer is close to one of the wheels on the same side as the first output shaft.

[0010] Preferably, the reducer is a worm gear reducer.

[0011] Preferably, the transmission ratio range of the reducer is 7-12.

[0012] Preferably, two driving gears are respectively provided at both ends of the second output shaft, an inner gear ring is provided in the wheel hub, and each driving gear extends into the corresponding inner gear ring and engages for transmission.

[0013] Preferably, it further comprises a rotating shaft, which is rotatably arranged on the frame and is respectively connected to the two wheels.

[0014] The utility model also provides a snow sweeper, comprising the above-mentioned self-propelled system.

[0015] Beneficial effects of the utility model:

[0016] The present utility model discloses a self-propelled snowplow system. When the power source outputs power through the first output shaft and transmission assembly to rotate the churn shaft, the first transmission wheel also transmits power synchronously to the two wheels via the first transmission belt, the second transmission wheel, and the speed reducer, thereby achieving the self-propelled function of the snowplow during operation. The power source for the self-propelled wheels and the rotation of the churn shaft is the same, thus eliminating the need for a separate power device to drive the two wheels for self-propelled operation. This fully utilizes the power source of the power source, simplifies the overall structure, and reduces manufacturing costs.

[0017] At the same time, the first transmission wheel, the first transmission belt, the second transmission wheel and the reducer are used in combination, which will not take up extra space of the entire machine, and can realize power transmission in a small space. Moreover, the rotation speed can be reduced to meet the self-propelled speed of the wheel, thereby ensuring the stability of self-propelled movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1-7 As shown, in one embodiment of the present invention, a self-propelled system and a snowplow are provided, wherein the self-propelled system includes a frame 10, a power body, a transmission assembly 30, a first transmission wheel 40, a reducer 50, a second transmission wheel 60, and a first transmission belt 70. The frame 10 is rotatably provided with a stirring basket shaft 11 and two wheels 12, the power body is mounted on the frame 10, the power body is provided with a first output shaft 20, and the transmission assembly 30 is transmission-connected to the first output shaft 20 and the stirring basket shaft 11.

[0035] The first transmission wheel 40 is fixedly mounted on the first output shaft 20. The reducer 50 is mounted on the frame 10 and is located below the first output shaft 20. The reducer 50 includes an input shaft 51 and a second output shaft 52. The second output shaft 52 is in driving connection with the two wheels 12. The axes of the second output shaft 52, the first output shaft 20, the stirring basket shaft 11, and the wheels 12 are parallel. The second transmission wheel 60 is fixedly mounted on the input shaft 51. The first transmission belt 70 is in driving connection with the first transmission wheel 40 and the second transmission wheel 60.

[0036] This embodiment discloses a self-propelled system and snowplow. When the power source outputs power through the first output shaft 20 and transmission assembly 30 to rotate the churn shaft 11, the first transmission wheel 40 also synchronously transmits power to the two wheels 12 via the first transmission belt 70, the second transmission wheel 60, and the speed reducer 50, thereby achieving the self-propelled function of the snowplow during operation. The power source for the self-propelled wheels 12 and the rotation of the churn shaft 11 is the same. Therefore, there is no need to design an additional power device to drive the two wheels 12 for self-propelled operation. This fully utilizes the power source of the power source, simplifies the overall structure, and reduces manufacturing costs.

[0037] At the same time, the first transmission wheel 40, the first transmission belt 70, the second transmission wheel 60 and the reducer 50 are used in combination without occupying extra space of the entire machine. Power transmission can be achieved in a small space. Moreover, the rotation speed can be reduced to meet the self-propelled speed of the wheel 12, thereby ensuring the stability of self-propelled movement.

[0038] In one embodiment, the second transmission wheel 60 is located between the stirring basket shaft 11 and the second output shaft 52, and the first transmission wheel 40 and the second transmission wheel 60 are connected by a semi-cross transmission through a first transmission belt 70. The axis of the first transmission wheel 40 and the axis of the second transmission wheel 60 are staggered in space, and the staggered angle is 90°. By designing the transmission form of the first transmission wheel 40 and the second transmission wheel 60 as a semi-cross transmission, the rotation direction of the first output shaft 20 and the second output shaft 52 can be converted within the limited space below the frame 10. In this way, the reducer 50 can reduce the high speed of the input shaft 51 and output it from the second output shaft 52, thereby meeting the self-propelled speed of the wheel 12.

[0039] Furthermore, the first transmission belt 70 is a round belt. Round belts effectively transmit power from the first output shaft 20. Their efficient transmission performance helps save energy and improve operational efficiency. Round belts also have a long service life and a relatively long replacement cycle, thereby reducing maintenance costs for the entire machine.

[0040] In one embodiment, a rotating member 80 is rotatably mounted on the frame 10. The rotating member 80 utilizes a deep groove bearing and is positioned above the second transmission wheel 60. The rotation axis 90 of the rotating member 80 is parallel to the axis of the second transmission wheel 60, and the first transmission belt 70 abuts against the outer sidewall of the rotating member 80. By designing the rotating member 80 to abut against the first transmission belt 70, the rotating member 80 prevents the first transmission belt 70 from contacting the frame 10, thereby avoiding wear caused by friction between the first transmission belt 70 and the frame 10. Furthermore, the rotatable nature of the rotating member 80 also reduces friction between it and the first transmission belt 70, thereby helping to extend the service life of the first transmission belt 70.

[0041] In one embodiment, the transmission assembly 30 includes a third transmission wheel 31, a fourth transmission wheel 32, and a second transmission belt. The third transmission wheel 31 is mounted on the first output shaft 20, and the fourth transmission wheel 32 is mounted on the churn shaft 11. The second transmission belt connects the third and fourth transmission wheels 31 and 32. The first transmission wheel 40 is positioned between the power source and the third transmission wheel 31, and the speed reducer 50 is located near a wheel 12 on the same side as the first output shaft 20. The position of the first transmission wheel 40 does not affect the operation and transmission of the third transmission wheel 31, thereby ensuring the normal operation of the churn shaft 11. Furthermore, power transmission can be achieved in a confined space, thereby enabling the self-propelled function of the wheel 12.

[0042] In one embodiment, the reducer 50 is a worm gear reducer, and the transmission ratio range of the reducer 50 is 7 to 12. The worm gear reducer has good deceleration effect, compact structure, small size, and is more convenient to use in a narrow space.

[0043] In one embodiment, two drive gears 53 are provided at each end of the second output shaft 52. The hub of the wheel 12 is provided with an internal gear ring 121, and each drive gear 53 extends into and meshes with a corresponding internal gear ring 121. After the speed reducer 50 reduces the speed of the input shaft 51, the speed is output through the second output shaft 52. If the speed of the second output shaft 52 is still too high to meet the required self-propelled speed of the wheel 12, the drive gears 53 are designed to cooperate with the internal gear ring 121 in the wheel 12 to achieve a secondary reduction in speed. This not only drives the wheel 12 but also reduces the speed of the second output shaft 52, thereby ensuring that the self-propelled speed of the wheel 12 meets the required speed.

[0044] In one embodiment, in order to improve the walking stability of the two wheels 12 , the self-propelled system further includes a rotating shaft 90 , which is rotatably disposed on the frame 10 and is respectively connected to the two wheels 12 .

[0045] Of course, a protective cover 13 is provided on the frame 10 to cover the outside of the transmission structure, thereby ensuring its normal operation.

[0046] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
