[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] It should be noted that, in the present application specification, when a component is considered to be "disposed on" another component, it may be connected to or directly disposed on another component, or there may be a central component at the same time; when a component is considered to be "connected to" another component, it may be directly connected to another component or there may be a central component at the same time.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] In the related art, the snow removal equipment has a snow discharge drum for discharging snow, which rotates to change the direction of snow discharge. The snow discharge drum also has a snow guide cover, which can rotate up and down relative to the ground, so as to change the snow discharge angle. In order to protect the transmission rope inside the rope assembly, a sheath is usually set on the outside of the transmission rope, which can prevent rainwater and impurities from entering the rope assembly, and avoid damage caused by freezing of the rope assembly or impurities entering at low temperatures. A part of the transmission rope is exposed to the external environment, and the length of this part of the transmission rope is designed to just meet the range of rotation angles required by the snow guide cover in the initial state.

[0031] However, after experiencing the alternation of high and low temperatures, the outer sheath of the rope assembly is prone to shortening. This means that the length of the transmission rope exposed to the outside becomes longer than the initial state. In this state, when the transmission rope of the same length as the initial state is pulled, the range of the snow guide cover's rotation angle is limited, that is, the control of the snow discharge angle is affected by the shortening of the sheath length.

[0032] Based on this, the applicant conducted in-depth research to solve the technical problem of how to ensure that the sheath of the rope assembly does not change in length, so as to form the technical solution of the present application.

[0033] The utility model proposes a snow removal device 100 and a snow removal machine. The snow removal device 100 can be detachably mounted on a self-moving device. The self-moving device generates a predetermined snow removal path based on the snow removal area set by the user. The self-moving device can be a mobile carrier such as a crawler vehicle or a wheeled vehicle that can have a mounting position for the snow removal device 100. The self-moving device and the snow removal device 100 are combined to form a snow removal machine to complete automatic snow removal work; the snow removal device 100 is used to complete the snow removal work in a predetermined area along the predetermined path generated by the self-moving device under the drive of the self-moving device.

[0034] The structure of the snow removal equipment 100 in the present application is described in detail below.

[0035] See also Figures 1 to 3 The utility model proposes a snow removal device 100, comprising: a snow discharge drum 10, a snow guide cover 20 rotatably arranged on the snow discharge drum 10, and a rope assembly 30 for pulling the snow guide cover 20 to rotate; the rope assembly 30 comprises: a transmission rope 31, the transmission rope 31 is transmission-connected to the snow guide cover 20; a plurality of sheaths 32, the plurality of sheaths 32 are sleeved on the outside of the transmission rope 31, and are connected end to end along the length direction of the transmission rope 31, and the sheaths 32 are metal sheaths.

[0036] Among them, the snow removal equipment 100 may include an impeller assembly, which may include multiple centrifugal impellers. The impeller assembly can be installed at the bottom of the snow removal equipment 100, and the impeller assembly can directly contact the accumulated snow. When the impeller assembly rotates at a high speed, the impeller assembly can collect the rolled snow into the interior of the snow removal equipment 100 under the action of centrifugal force and throw the accumulated snow out through the snow discharge drum 10.

[0037] One end of the rope assembly 30 is connected to the snow guide cover 20, and the other end of the rope assembly 30 is connected to a power device such as a motor 40, so that the power device such as the motor 40 can drive the rope assembly 30 to slide in the sheath 32, so that the rope assembly 30 pulls the snow guide cover 20 and rotates up and down relative to the snow discharge drum 10 to change the snow guiding direction.

[0038] In order to protect the transmission rope 31 inside the rope assembly 30, a sheath 32 is usually provided on the outside of the transmission rope 31 to prevent rainwater and impurities from entering the rope assembly 30, and to avoid damage caused by freezing of the rope assembly 30 or impurities entering at low temperatures. The sheath 32 provided in this embodiment is one of the core features of this embodiment. The metal sheath 32 has good anti-deformation characteristics under high and low temperature conditions, so it is suitable for long-term outdoor operations of the snow removal equipment 100, avoiding changes in the length of the sheath 32; multiple sheaths 32 are arranged end to end to extend to the required length.

[0039] Please refer to Figure 2 In some embodiments, the leading end of the sheath 32 has a curved surface portion 321 , and the trailing end of the sheath 32 has an avoidance recess 322 matched with the curved surface portion 321 .

[0040] The inner hollow of the sheath 32 forms a threading channel, and the inner wall of the threading channel forms an arc portion 321 toward the outer side of the sheath 32. Specifically, the arc portion 321 can be a rounded structure; the avoidance recess 322 at the rear end of the sheath 32 is adapted to the arc portion 321 at the head end of the sheath 32, and adjacent sheaths 32 can be connected end to end, as shown in the attached Figure 2 As shown, the head end of the sheath 32a and the tail end of the sheath 32b abut against each other to achieve the head-to-tail connection of adjacent sheaths 32. The cooperation between the arc surface 321 and the avoidance recess 322 makes the sheath 32 formed by connecting multiple sheaths 32 have a certain bending performance as a whole, which can adapt to the bending changes of the rope assembly 30 during use.

[0041] In addition, since the matching design of the arc surface 321 and the avoidance recess 322 provides space for relative movement between the respective sheaths 32, during snow removal, after snow water or moisture in the air enters the movement space between adjacent sheaths, the thin ice layer formed under the action of low temperature is squeezed and destroyed during the bending process. Therefore, the antifreeze performance of the rope assembly 30 at low temperatures is improved.

[0042] Please refer to Figure 2 In some embodiments, the rope assembly 30 further includes a deformable inner lining tube 33 , wherein the inner lining tube 33 is located between the transmission rope 31 and the sheath 32 , and there is a movable gap between the inner lining tube 33 and the transmission rope 31 .

[0043] There is an active gap between the inner lining tube 33 and the transmission rope 31 to allow the transmission rope 31 to slide in the inner lining tube 33, and the sheath 32 is sleeved on the outer side of the inner lining tube 33. The inner lining tube 33 has a deformable feature and a certain toughness, and can be deformed as the transmission rope 31 bends, so that when the transmission rope 31 bends, it can avoid being stuck with the inner wall of the inner lining tube 33, which is beneficial to improving the adaptability of the rope assembly 30. The inner lining tube 33 is located between the sheath 32 and the transmission rope 31, which also avoids the transmission rope 31 from generating a large friction resistance with multiple sheaths 32 during the sliding process, and the active gap between the inner lining tube 33 and the transmission rope 31 provides favorable conditions for the smooth sliding of the transmission rope 31.

[0044] Furthermore, in some embodiments, the active gap is injected with lubricant.

[0045] Injecting lubricant into the movable gap between the inner liner tube 33 and the transmission rope 31 is beneficial to improving the smoothness of sliding of the transmission rope 31 in the inner liner tube 33 and reducing the wear between the transmission rope 31 and the inner liner tube 33, thereby reducing the maintenance frequency of the rope assembly 30 and reducing replacement and labor costs.

[0046] In some embodiments, the ratio of the inner diameter of the liner tube 33 to the outer diameter of the transmission rope 31 ranges from 1.1 to 1.15.

[0047] Since the snow removal equipment 100 usually operates in a low temperature and high humidity environment, moisture, rain and snow in the air gather in the active gap and condense into ice. The size of the active gap affects the thickness of the ice. The thicker the ice is, the more difficult it is to break the ice. In one embodiment, the ratio of the inner diameter of the inner liner 33 to the outer diameter of the transmission rope 31 should not be too large, and the range is controlled to be 1.1 to 1.15. The specific ratio can be but is not limited to 1.1, 1.12, 1.14 and 1.15. Within this range, it does not affect the smoothness of the transmission rope 31 sliding in the inner liner 33, and avoids the thick ice layer condensing in the active gap. The thin ice layer condensed in the active gap can be destroyed during the sliding activity of the transmission rope 31.

[0048] In some embodiments, the ratio of the inner diameter of the sheath 32 to the outer diameter of the liner tube 33 is in the range of 1.05 to 1.1.

[0049] In order to adapt to the length of the inner liner 33 and the transmission rope 31, multiple sheaths 32 are connected end to end. The moisture and rain and snow in the working environment of the snow removal equipment 100 can easily enter the inner liner 33 and the sheath 32 through the gaps between the sheaths 32 and condense into ice. Since the sheath 32 and the inner liner 33 are directly in contact with or close to the external environment, it is easier to gather rain and snow. Therefore, it is necessary to more strictly control the gap between the sheath 32 and the inner liner 33. Therefore, the ratio of the inner diameter of the sheath 32 to the outer diameter of the inner liner 33 is controlled in the range of 1.05 to 1.1, and the specific ratio can be but not limited to 1.05, 1.07 and 1.08. The gap between the inner liner 33 and the sheath 32 is controlled to a smaller value. Even if a thin ice layer is formed therein, it can be destroyed in the relative movement of the sheaths 32, that is, the bending squeezing effect can destroy the thin ice layer.

[0050] In some embodiments, the transmission rope 31 is a metal rope, and / or the liner tube 33 is a non-metallic liner tube 33 .

[0051] The inner lining tube 33 can be an inner lining tube 33 made of Teflon. Since Teflon has good self-lubricating properties, even without adding lubricants, the Teflon tube and the object in contact with it can achieve relatively smooth sliding. The self-lubricating property of the Teflon tube can reduce wear when the transmission rope 31 slides. The inner lining tube 33 can also be an inner lining tube 33 made of nylon. The inner surface of the nylon tube is relatively smooth. When the transmission rope 31 slides, the nylon tube can reduce the friction between the transmission rope 31 and the nylon tube, reduce wear, and extend the service life of the rope assembly 30.

[0052] The transmission rope 31 can be made of metal materials such as stainless steel, copper or aluminum. The transmission rope 31 made of metal has good corrosion resistance, strength and wear resistance.

[0053] In some embodiments, the snow removal device 100 further includes a motor 40 and a winding mechanism 50 connected to the motor 40 , one end of the rope assembly 30 is connected to the snow guide cover 20 , and the other end of the rope assembly 30 is connected to the winding mechanism 50 .

[0054] Specifically, a portion of the transmission rope 31 is exposed to the external environment, and the motor 40 drives the winding mechanism 50 to work under the action of an external power source. The winding mechanism 50 may include a winding drum, and the transmission rope 31 is wound on the winding drum. Driven by the motor 40, the winding drum can rotate to control the winding and release of the transmission rope 31. The transmission rope 31 exposed to the external environment passes in or out of the sheath 32. The length of the transmission rope 31 exposed to the external environment also changes with the winding and release of the winding mechanism 50. The length of the transmission rope 31 exposed to the outside is designed to just meet the range of rotation angles required by the snow guide hood 20 in the initial state.

[0055] Please refer to Figure 5 The rope assembly 30 also has an end sleeve 34 , one end of the end sleeve 34 is arranged at the terminal end of the plurality of sheaths 32 , and the other end is connected to the winding mechanism 50 or the snow discharging drum 10 .

[0056] Specifically, one end of the end sleeve 34 has a receiving cavity capable of receiving part of the sheath 32. A plurality of sheaths 32 form a sheath 32 as a whole, and a part of the first and last two sheaths 32 are received in the receiving cavity of the end sleeve 34. This means that the sliding of the sheath 32 as a whole along the transmission rope 31 is limited by the end sleeve 34. In this way, it is beneficial to have a small gap between adjacent sheaths 32 to prevent rain and snow in the environment from penetrating into the sheath 32 through the gap and freezing. A threaded interface can be provided at the other end of the end sleeve 34. The sheath 32 as a whole passes through the threaded interface of the end sleeve 34, with one end connected to the winding mechanism 50 and the other end connected to the snow-discharging drum 10, so that the arrangement of the rope assembly 30 can fit the shape of the snow-discharging drum 10, which is beneficial to improving the stability of the rope assembly 30 and the aesthetics of the snow removal device 100.

[0057] The utility model further provides a snow removal machine, comprising a snow removal device 100 and a self-moving device, wherein the snow removal device 100 can be detachably mounted on the self-moving device.

[0058] The self-moving device is a mobile vehicle body that can adopt a variety of designs, such as a tracked vehicle, a wheeled vehicle, etc., and can move freely under different terrains and environmental conditions. The self-moving device has precise positioning technology, such as a global positioning system and an inertial navigation system, which enables the self-moving device to accurately locate. The self-moving device can also be equipped with an obstacle avoidance system, such as ultrasonic obstacle avoidance, visual obstacle avoidance, infrared obstacle avoidance, etc., which can avoid obstacles during operation and move along a preset path. The self-moving device is equipped with the snow removal device 100 described in the above embodiment, which can efficiently clear the snow in the designated area under the drive of the self-moving device, and the entire cleaning process does not require manual operation. It has the ability to independently complete the task and reduces manpower input.
