Description

Technical Field

[0001] The present invention relates to the technical field of snow shoveling equipment, and in particular to an automatic ice-breaking and snow shoveling equipment and a control method thereof. Background Art

[0002] Snow can benefit mankind, but it can also bring disasters to mankind. It can block traffic, close highways, and ground civil aviation. It is also very easy to cause traffic accidents, causing huge losses to people's lives and property, and seriously affecting people's normal lives. In winter, clearing snow has become the main task of various municipal departments. With the advancement of technology, clearing snow has become more and more mechanized, so snow-clearing equipment is needed to clear the snow. Snow-clearing equipment includes large-scale snow-clearing equipment such as snowplows and snowplows. Snowplows are a type of machinery specially designed for digging and removing snow, aiming to improve the efficiency and safety of winter snow removal operations.

[0003] However, when the existing snowplows are excavating snow, the weight of the snow excavated each time is different, and the weight of the snow excavated each time is not weighed, so it is impossible to determine whether ice cubes are encountered. When ice cubes are encountered, an ice-breaking head is required to crush the ice cubes. However, the ice-breaking head is set on other mechanical equipment, which makes it impossible to ensure that the maximum feed stroke each time is greater than the maximum excavation stroke of the snowplow, and the ice-breaking travel distance cannot be guaranteed to be large enough, so that a sufficient amount of snow cannot be excavated after breaking the ice, resulting in problems such as insufficient snow excavation and uneven energy ratio, which increases the economic cost of the snowplow equipment. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic ice-breaking and snow-digging equipment, so as to solve the problem that during the snow-digging operation in the prior art, ice blocks affect the snow-digging effect and efficiency, resulting in a small amount of snow digging and uneven energy ratio.

The knocking mechanism is slidably connected to the fixing frame. One end of the knocking mechanism is attached to one side of the cam. The rotating shaft drives the cam to rotate. The cam pushes the knocking mechanism to move when rotating.

[0009] Preferably, the feed rotating assembly comprises a cylinder, a connecting plate, a connecting frame, a hollow rotating shaft and a servo motor;

[0010] One surface of the connecting plate is fixedly connected to the end of the cylinder, and the other surface of the connecting plate is provided with the connecting frame and the servo motor. The hollow rotating shaft passes through the connecting frame, one end of the hollow rotating shaft is fixedly connected to the ice breaking head, and the rotating shaft passes through the hollow rotating shaft and is transmission-connected to the servo motor.

[0011] Preferably, the knocking assembly further includes a return spring, one end of which is fixed to the fixing frame, and the other end of which is fixed to the knocking mechanism.

[0013] The two ends of the knocking rod are fixedly connected to the fixing plate and the knocking head respectively, the fixing plate is fitted with one side of the cam, and the fixing plate is fixedly connected to the return spring;

[0014] The guide block is arranged on the knocking rod, and the guide block is slidably connected to the fixing frame.

[0015] Preferably, the automatic ice-breaking and snow-shoveling equipment further comprises a heating device, and the heating device is arranged inside the ice-breaking head.

[0016] Preferably, a cavity is provided inside the ice-breaking head, an air inlet is provided inside the cavity, the air inlet is located directly below the heating device, and a through hole is provided on the top of the cavity.

[0017] Preferably, the striking assembly further includes a fan blade and an air inlet pipe, wherein the fan blade is arranged on the rotating shaft and is located inside the hollow rotating shaft, one end of the air inlet pipe is arranged inside the hollow rotating shaft, and the other end of the air inlet pipe is arranged inside the ice-breaking head.

[0018] According to another aspect of the present invention, a control method for an automatic ice-breaking and snow-shoveling device is provided, the control method comprising:

[0019] Obtaining the weight of the load on the snow-removing device;

When it is determined that the amount of snow plowed is insufficient, the ice-breaking device is started to break the ice. After the ice-breaking device is started, if it is detected that the ice-breaking is difficult, it is necessary to increase the speed of the ice-breaking head and start the heating device to assist in ice-breaking. The maximum feed stroke of the ice-breaking device is greater than the maximum plowing stroke of the snow-plowing device to ensure that the ice-breaking amount is large enough, so that the snow-plowing device can plow a sufficient amount of snow after breaking the ice.

[0024] The above technical solution of the present invention has the following beneficial technical effects:

[0025] 1. The automatic ice-breaking and snow-dredging equipment, through the cooperation between the cylinder, the rotating assembly and the ice-breaking head, is provided with a weighing device in the snow-dredging device during the snow-dredging operation to obtain the weight of the current snow dug. When the weight of the snow dug is less than the preset weight, it is judged that ice is encountered. When ice is encountered, the ice can be crushed, and the ice-breaking head can be heated by providing a heating device to further improve the ice-breaking efficiency. The maximum feed stroke of the ice-breaking head is greater than the maximum digging stroke of the snow-dredging device to ensure that the ice-breaking travel is large enough, so that a sufficient amount of snow can be dug after breaking the ice, avoiding the problem of unequal energy ratio caused by the small amount of snow dug. Through such a setting, the economic cost of the snow-dredging equipment is reduced.

[0026] 2. The automatic ice-breaking and snow-shoveling equipment can perform knocking operations on the inside of the ice-breaking head through the cooperation between the rotating shaft, cam, fixed frame and knocking mechanism. Through this setting, the ice attached to the ice-breaking head can be vibrated and dropped, preventing the ice from adhering to the surface of the ice-breaking head and affecting the ice-breaking effect, thereby further improving the work efficiency during ice breaking.

[0027] 3. The automatic ice-breaking and snow-shoveling equipment can transmit the external wind force to the inside of the ice-breaking head through the cooperation between the fan blades, the air inlet pipe, the cavity and the air inlet hole. Then, under the heating of the heating device, the cold wind is converted into hot air, which flows into the cavity of the ice-breaking head to heat the ice-breaking head, thereby avoiding problems such as poor local heating effect and further improving the heating effect.

[0045] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0046] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] In one embodiment, reference Figure 1-Figure 8 An automatic ice-breaking and snow-plowing device comprises a machine body 1, a snow-plowing device 2, a weighing device 3 and an ice-breaking device 4. The weighing device 3 is arranged on the snow-plowing device 2 and is used to weigh the load on the snow-plowing device 2. The snow-plowing device 2 is arranged on the machine body 1. The ice-breaking device 4 comprises a feeding rotating assembly 41 arranged on the machine body and an ice-breaking head 42 connected to the output end of the feeding rotating assembly 41. The maximum feeding stroke of the ice-breaking device 4 is greater than the maximum excavating stroke of the snow-plowing device 2.

[0048] By adopting such a scheme, when the snow-clearing device 2 is clearing snow, when the weight of the cleared snow is less than the preset weight, it can be determined whether ice cubes are encountered. When ice cubes are encountered, the ice cubes can be crushed. The maximum feed stroke of the ice-breaking head 42 is greater than the maximum excavation stroke of the snow-clearing device 2 to ensure that the ice-breaking travel distance is large enough, so that a sufficient amount of snow can be cleared after breaking the ice, avoiding the problem of unequal energy ratio caused by small amount of snow cleared. Through such an arrangement, the economic cost of the snow-clearing equipment is reduced.

[0049] During specific operation, the snow-clearing device 2 is controlled by the machine body 1 to perform snow-clearing operations, and then the snow-clearing device 2 is used to collect the accumulated snow. The weight of the accumulated snow increases the overall weight of the weighing inner bucket 31, and the weighing inner bucket 31 squeezes the supporting spring 33. The distance between the weighing inner bucket 31 and the inner wall of the snow-clearing device 2 is reduced. When the supporting spring 33 is compressed to a fixed length, the weighing inner bucket 31 contacts the weighing device 32, and the overall weight of the weighing inner bucket 31 is shared between the supporting spring 33 and the weighing device 32. At this time, the first weight shared by the weighing device 32 can be obtained, and the fixed second weight shared when the supporting spring 33 is compressed to a fixed length. The single snow-clearing weight can be obtained by adding the first weight to the second weight and subtracting the self-weight of the weighing inner bucket 31. Under the setting of the support spring 33, the weighing inner bucket 31 is supported with the snow-digging device 2. When there is no snow inside the snow-digging device 2, the support spring 33 will push the weighing inner bucket 31 to reset, so as to facilitate the subsequent re-measurement and reduce the load of the weighing device 32, thereby ensuring the accuracy of the measurement of the weighing device 32. If the weight of snow dug in the snow-digging device 2 is less than the preset weight, it is judged that ice is encountered and ice breaking is required. The starting cylinder 411 moves the feeding rotating assembly 41 downward, and drives the ice-breaking head 42 to feed and rotate through the feeding rotating assembly 41. It should be noted that after the ice-breaking head 42 is started, the ice-breaking feeding stroke within the preset time is compared with the pre-set feeding stroke. If the actual feeding stroke of the ice-breaking head 42 within the preset time is less than the preset feeding stroke, it means that the ice breaking is slow and it is judged that ice breaking is difficult. At this time, the rotation speed of the ice-breaking head 42 is increased to speed up the ice breaking efficiency. Furthermore, the maximum feeding stroke of the ice breaking device is greater than the maximum excavation stroke of the snow excavating device, ensuring that the ice breaking travel is large enough, so that the snow excavating device can excavate a sufficient amount of snow after breaking the ice. Preferably, a heating device 5 is provided inside the ice breaking head, and the ice breaking head 42 is heated by the heating device 5 to further promote ice breaking work and improve work efficiency.

[0050] In other optional situations, the weighing device 32 can be configured as a pressure sensor and electrically connected to an external display to measure weight.

[0051] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7An automatic ice-breaking and snow-digging device comprises a machine body 1, a snow-digging device 2, and a weighing inner bucket 31 and a weighing device 32 are respectively arranged inside the snow-digging device 2, the weighing device 32 is used to weigh the weighing inner bucket 31, and the snow-digging device 2 is used to dig snow from the accumulated snow; a cylinder 411 is fixed to the side wall of the machine body 1, and a connecting plate 412 of a feeding rotating component 41 is fixedly connected to the output end of the cylinder 411, and an end of the feeding rotating component 41 is fixedly connected to an ice-breaking head 42, and the ice-breaking head 42 is used to break ice in the accumulated snow; a heating device 5 is arranged inside the ice-breaking head 42 to heat the ice-breaking head 42; a knocking component 43 is arranged inside the ice-breaking head 42 to knock the ice inside the ice-breaking head 42 For knocking and vibration, the knocking component 43 includes a rotating shaft 431 arranged inside the feeding rotating component 41, the end of the rotating shaft 431 is fixedly connected with a cam 432, the surface of the cam 432 is fixedly connected with a fixing frame 433 through a bearing, the fixing frame 433 is internally slidably connected with a knocking mechanism 434, one end of the knocking mechanism 434 is attached to the surface of the cam 432, the surface of the knocking mechanism 434 is fixedly connected with a return spring 435, the end of the return spring 435 is fixed on the fixing frame 433, the surface of the rotating shaft 431 is fixedly connected with a fan blade 436, and air inlet pipes 437 are arranged on both sides of the fan blade 436, and the air inlet pipes 437 are respectively fixed inside the feeding rotating component 41 and the ice breaking head 42.

[0052] With such a scheme, the feeding rotating assembly 41 drives the knocking assembly 43 to move, so that the knocking assembly 43 knocks on the inside of the ice-breaking head 42, causing the inside of the ice-breaking head 42 to vibrate, thereby vibrating and cleaning the ice cubes attached to the surface of the ice-breaking head 42 during ice breaking, thereby preventing the ice cubes from remaining on the surface of the ice-breaking head 42 and affecting the ice-breaking efficiency.

[0053] During specific operation, first, the rotation of the rotating shaft 431 can drive the cam 432 to rotate. When the highest protruding position of the cam 432 hits the surface of the knocking mechanism 434 during the rotation of the cam, the knocking mechanism 434 can be attached to the inside of the ice-breaking head 42 to knock the inside of the ice-breaking head 42. On the contrary, when the lowest recessed position of the cam 432 hits the surface of the knocking mechanism 434 during the rotation of the cam, the knocking mechanism 434 will be moved away from the inside of the ice-breaking head 42. Under the setting of the fixed frame 433, it can play a guiding and limiting role for the fixed frame 433. Through the setting of the reset spring 435, it can reset the knocking mechanism 434 when it is at the lowest point, and when the rotating shaft 431 rotates, the fan blade 436 can be rotated, so that it can convert the external gas into wind force and transport it to the inside of the air inlet pipe 437, and then transport it to the inside of the ice-breaking head 42 through the air inlet pipe 437.

[0054] In a preferred embodiment, the feed rotating assembly 41 includes a cylinder 411, a connecting plate 412, a connecting frame 413, a hollow rotating shaft 414 and a servo motor 415; one surface of the connecting plate 412 is fixedly connected to the end of the cylinder 411, and the other surface of the connecting plate 412 is provided with a connecting frame 413 and a servo motor 415, the hollow rotating shaft 414 passes through the connecting frame 413, one end of the hollow rotating shaft 414 is fixedly connected to the ice breaking head 42, and the rotating shaft 431 passes through the hollow rotating shaft 414 and is transmission-connected to the servo motor 415. The knocking assembly 43 also includes a return spring 435, one end of which is fixed to the fixing frame 433, and the other end of the return spring 435 is fixed to the knocking mechanism 434. The knocking mechanism 434 includes a knocking rod 4341, a fixed plate 4342, a knocking head 4343 and a guide block 4344; the two ends of the knocking rod 4341 are fixedly connected to the fixed plate 4342 and the knocking head 4343 respectively, the fixed plate 4342 and one side of the cam 432 are fitted together, and the fixed plate 4342 and the return spring 435 are fixedly connected; the guide block 4344 is arranged on the knocking rod 4341, and the guide block 4344 and the fixed frame 433 are slidably connected.

[0055] Through such a setting, the feed rotating assembly 41 drives the rotating shaft 431 to rotate, thereby driving the cam 432 to rotate, and realizing the reciprocating motion of the knocking mechanism 434 inside the ice-breaking head 42, knocking the inside of the ice-breaking head 42, so as to vibrate the surface of the ice-breaking head 42, further improving the efficiency of the ice-breaking head 42, and at the same time promoting the separation of ice and snow attached to the surface of the ice-breaking head 42, and preventing the ice and snow remaining on the surface of the ice-breaking head 42 from affecting the subsequent ice-breaking effect. In a preferred case, a guide block 4344 is provided on the knocking rod 4341, and the guide block 4344 is slidably connected to the fixing frame 433, and the fixing plate 4342 and the fixing frame 433 are connected by a reset spring 435, so that when the fixing plate 4342 is squeezed by the cam 432, it drives the knocking rod 4341 to move, and the reset spring 435 makes the knocking rod 4341 reciprocate within a limited range, and the guide block 4344 makes the knocking rod 4341 move in a preset direction, so that it can better knock on the inner wall of the ice-breaking head 42, and the vibration effect of the ice-breaking head 42 is better.

[0056] In a preferred case, the driving icebreaker head 42 of the feeding rotating assembly 41 rotates, and the speed of the icebreaker head 42 is adjusted by controlling the output power of the servo motor 415, and the knocking assembly 43 can be rotated synchronously with the rotation of the feeding rotating assembly 41. It should be noted that the servo motor 415 and the rotating shaft 431 are driven by gear transmission, preferably, bevel gear meshing transmission is adopted, and the driving effect is better. The transmission method is not limited here. In optional cases, synchronous belt transmission or gear pair can be adopted, or the servo motor 415 can be directly used to drive the rotating shaft 431 to rotate, as long as the rotating shaft 431 can rotate and the structural stability during the knocking process is guaranteed.

[0057] Reference Figure 5 , Figure 6 The ice-breaking head 42 has a cavity 421 formed inside, an air inlet 422 formed inside the cavity 421, and the air inlet 422 is located directly below the heating device 5. A vent 423 is formed on the top of the cavity 421. The striking assembly 43 further includes a fan blade 436 and an air inlet pipe 437. The fan blade 436 is disposed on the rotating shaft 431 and is located inside the hollow rotating shaft 414. One end of the air inlet pipe 437 is disposed inside the hollow rotating shaft 414, and the other end of the air inlet pipe 437 is disposed inside the ice-breaking head 42.

[0058] With such a solution, when the wind enters the ice-breaking head 42, the wind flows from top to bottom, and the wind passes through the heating device 5 and enters the cavity 421 of the ice-breaking head 42 through the air inlet 422, so as to heat the surface of the ice-breaking head 42 and improve the ice-breaking efficiency. Preferably, the heating device 5 is arranged near the bottom of the ice-breaking head 42, that is, near the drilling head of the ice-breaking head 42. With such an arrangement, the temperature of the ice-breaking head 42 is better heated from the drilling head, so that the heat can be reasonably used.

[0059] During specific operation, when wind passes through the heating device 5 , it is heated to hot air, and the hot air is transported to the inside of the cavity 421 through the air inlet 422 , so that it heats the inside of the ice-breaking head 42 , and then the wind is discharged through the vent 423 .

[0060] Another aspect of the present invention provides a control method for automatic ice-breaking and snow-shoveling equipment, including: obtaining the weight of the load on the snow-shoveling device 2; if the weight of the load is less than a preset weight, starting the feed rotating component 41 to drive the ice-breaking head 42 to feed and rotate; obtaining the feed stroke of the ice-breaking head 42 within a preset time; if the feed stroke within the preset time is less than the preset stroke, increasing the rotation speed of the ice-breaking head 42.

[0061] Specifically, the snow shoveling device 2 is controlled by the machine body 1 to perform snow shoveling operation, and the snow shoveling device 2 collects the accumulated snow in the weighing inner bucket 31 inside the snow shoveling device 2, so that the weighing inner bucket 31 squeezes the weighing device 32, thereby obtaining the weight of the snow shoveled inside the weighing inner bucket 31;

[0062] If the weight of the snow dug inside the weighing inner bucket 31 is less than the preset weight, the cylinder 411 is started to move the feeding rotating assembly 41 downward, and the feeding rotating assembly 41 drives the ice breaking head 42 to feed and rotate;

[0063] The feeding stroke of the ice-breaking head 42 within the preset time is obtained. If the feeding stroke within the preset time is less than the preset stroke, the rotation speed of the ice-breaking head 42 is increased and the heating device 5 is started for auxiliary heating, so as to increase the feeding stroke in the later stage.

[0064] In a preferred case, during the feeding and ice-breaking process of the ice-breaking head 42, the feeding rotating assembly 41 is started, and the cam 432 at one end of the rotating shaft 431 is driven to rotate by the servo motor 415, thereby driving the knocking assembly 43 to move, so that the knocking assembly 43 performs a knocking operation on the inside of the ice-breaking head 42 when it rotates, thereby improving the feeding efficiency of the ice-breaking head 42.

[0065] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
