Technical Field

[0001] The present invention relates to the technical field of snowplows, and in particular to a self-propelled system and a snowplow. Background Art

[0002] Single-step snow blowers are mainly suitable for light snow and small snow areas. Therefore, single-step snow blowers are relatively compact. Single-step snow blowers are generally divided into two structures: without self-propelled function and with self-propelled function. Among them, the existing single-step snow blowers with self-propelled function generally achieve self-propelled function by adding an additional power device to drive the wheels to rotate.

[0003] Since the structure of the single-step snow blower itself is relatively compact, adding an additional power device 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 a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[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 a power body to achieve 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 present invention provides a self-propelled system, including a frame, on which a stirring basket shaft and two wheels are rotatably arranged; 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 is 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.

[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 column 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 of the wheel, and each of the driving gears extends into the corresponding inner gear ring and meshes for transmission.

[0014] The present invention also provides a snow sweeper, comprising the self-propelled system.

[0015] Beneficial effects of the present invention:

[0016] The present invention discloses a self-propelled system and snowplow. When the power body outputs power through the first output shaft and the transmission assembly to rotate the churning cage shaft, the first transmission wheel will also transmit power to the two wheels synchronously through the first transmission belt, the second transmission wheel and the reducer, thereby realizing the self-propelled function of the snowplow when working. The power source of the self-propelled wheels and the rotation of the churning cage shaft is the same. Therefore, there is no need to design an additional power device to drive the two wheels to self-propelled, which fully utilizes the power of the power body, simplifies the overall structure, and reduces the manufacturing cost.

[0034] like Figure 1-7 As shown, in one embodiment of the present invention, a self-propelled system and a snow sweeper are provided, wherein the self-propelled system comprises 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 cage 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 with the first output shaft 20 and the stirring cage shaft 11.

[0035] The first transmission wheel 40 is fixedly sleeved on the first output shaft 20, the reducer 50 is installed on the frame 10 and is located below the first output shaft 20, the reducer 50 is provided with an input shaft 51 and a second output shaft 52, the second output shaft 52 is transmission-connected with the two wheels 12, and the axes of the second output shaft 52, the first output shaft 20, the stirring cage shaft 11 and the wheels 12 are parallel. The second transmission wheel 60 is fixedly sleeved on the input shaft 51, and the first transmission belt 70 is transmission-connected with the first transmission wheel 40 and the second transmission wheel 60.

[0036] The self-propelled system and snowplow disclosed in this embodiment, when the power body outputs power through the first output shaft 20 and the transmission assembly 30 to rotate the churning cage shaft 11, the first transmission wheel 40 will also transmit power to the two wheels 12 synchronously through the first transmission belt 70, the second transmission wheel 60 and the reducer 50, so as to realize the self-propelled function of the snowplow when working. The power source of the self-propelled wheels 12 and the rotation of the churning cage shaft 11 is the same, so there is no need to design an additional power device to drive the two wheels 12 to self-propelled, which fully utilizes the power of the power body, simplifies the overall structure, and reduces the manufacturing cost.

[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 cooperation without occupying extra space of the whole machine. Power transmission can be achieved in a small space, and the rotation speed can be reduced to meet the self-propelled speed of the wheel 12, thereby ensuring the stability of self-propelled.

[0038] In one embodiment, the second transmission wheel 60 is located between the stirring cage 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 in the limited space under 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. The round belt can effectively transmit the power output by the first output shaft 20, and the efficient transmission performance helps to save energy and improve the operation efficiency. At the same time, the round belt has a long service life and a relatively long replacement cycle, thereby reducing the maintenance cost of the whole machine.

[0040] In one embodiment, a rotating member 80 is rotatably provided on the frame 10, and the rotating member 80 adopts a deep groove bearing. The rotating member 80 is located above the second transmission wheel 60, and 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 side wall of the rotating member 80. By designing the rotating member 80 to abut against the first transmission belt 70, the rotating member 80 will prevent the first transmission belt 70 from contacting the frame 10, thereby avoiding the wear problem caused by the friction between the first transmission belt 70 and the frame 10. At the same time, the rotatable characteristic of the rotating member 80 itself can also reduce the friction between it and the first transmission belt 70, which helps to ensure 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 arranged on the first output shaft 20, the fourth transmission wheel 32 is arranged on the stirring cage shaft 11, and the second transmission belt transmission connects the third transmission wheel 31 and the fourth transmission wheel 32. The first transmission wheel 40 is located between the power column and the third transmission wheel 31, and the reducer 50 is close to a wheel 12 on the same side as the first output shaft 20. The position of the first transmission wheel 40 will not affect the operation and transmission of the third transmission wheel 31, thereby ensuring the normal operation of the stirring cage shaft 11. At the same time, the power transmission can be realized in a small space, thereby realizing 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 driving gears 53 are respectively provided at both ends of the second output shaft 52, and an inner gear ring 121 is provided in the wheel hub of the wheel 12, and each driving gear 53 extends into the corresponding inner gear ring 121 and meshes with the transmission. After the speed reducer 50 reduces the speed of the input shaft 51, it outputs through the second output shaft 52. If the speed of the second output shaft 52 is still relatively fast and cannot meet the self-propelled speed requirement of the wheel 12, the driving gear 53 is designed to cooperate with the inner gear ring 121 in the wheel 12 to achieve secondary reduction, which not only realizes the driving of the wheel 12, but also realizes the reduction of the speed of the second output shaft 52, so that the self-propelled speed of the wheel 12 can meet the use requirements.

[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, so as to ensure its normal operation.

[0046] In the description of the present invention, a large number of specific details are described. However, it is understood that 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 description.

[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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
