Description

Technical Field

[0001] This utility model relates to the technical field of snow removal equipment, and in particular to a multi-functional snow sweeper spreader. Background Technology

[0002] In winter, due to the cold weather, highways, city roads, airport runways, squares, and scenic area roads are prone to snow accumulation and icing. Road icing typically includes frozen snow residue, ruts, melted snow, or other road water that forms a hard layer of ice in the cold season. This phenomenon not only causes great inconvenience to people's travel and transportation but also poses significant safety hazards, such as reduced friction between vehicle wheels and the road surface leading to skidding and inability to brake, and the risk of pedestrians slipping and falling. To solve the problem of road icing and snow and ensure traffic safety and smooth traffic flow, various snow removal equipment has emerged, among which snow spreaders play an important role in snow melting and removal operations.

[0003] Currently available spreaders have several shortcomings in application. Firstly, many spreaders lack precise control over spreading speed and quantity, resulting in uneven spreading and inconsistent application of de-icing agents or salt under varying road and weather conditions. Secondly, spreaders typically distribute de-icing agents or salt, which must be stored in the machine's internal storage compartment before application. However, the cold, damp winter climate causes these agents or salts to easily become damp and clump together, affecting spreading efficiency and potentially causing blockages, thus increasing maintenance difficulty and operating costs.

[0004] To address the aforementioned problems, existing technologies still fail to provide effective solutions, resulting in numerous inconveniences and safety hazards for snowplow spreaders in practical applications. This invention aims to provide a multi-functional snowplow spreader to solve these technical problems. Utility Model Content

[0036] The following is in conjunction with the appendix Figures 1-8 The embodiments of this utility model will be described in detail below.

[0037] Example 1:

[0038] Reference Figures 1 to 4 As shown, a multi-functional snowplow spreader includes:

[0039] Main support frame 1, connected to the snowplow for mounting the spreader;

[0040] Storage compartment 2 is installed on the main support 1, with a sealing cover 202 on the top and a discharge pipe 201 at the bottom;

[0041] The spreading disc 3 is located on the main support 1 and is directly below the discharge pipe 201. Multiple dividing plates 301 are evenly arranged on the upper surface of the spreading disc 3. The dividing plates 301 are used to control the spreading direction and ensure that the de-icing agent is evenly distributed.

[0042] The crushing mechanism is located at the storage bin 2 and the discharge pipe 201. It is used to crush the agglomerated de-icing agent or salt, and also has the function of clearing the discharge pipe 201 to prevent blockage.

[0043] The drive mechanism, located on the storage chamber 2, includes a drive shaft 501 that passes through the storage chamber 2 and the discharge pipe 201. The lower end of the drive shaft 501 passes through the discharge pipe 201 and is connected to the spreading disc 3. The drive shaft 501 drives the crushing mechanism to run and the spreading disc 3 to rotate.

[0044] The rotation of the drive shaft 501 effectively breaks up agglomerated de-icing agent, preventing blockage of the discharge pipe 201 and ensuring uniform spreading. Simultaneously, by adjusting the rotation speed of the drive shaft 501, the rotation speed of the spreading disc 3 is adjustable, thereby controlling the amount and range of de-icing agent spread. Furthermore, the design of the dividing plate 301 on the spreading disc 3 further optimizes the spreading effect, avoids waste of de-icing agent, and improves operational efficiency.

[0045] The main support 1 has a bottom support frame 6 installed on its side wall. The lower end of the spreading disc 3 is rotatably mounted on the bottom support frame 6. The lower end of the drive shaft 501 passes through the spreading disc 3 and is rotatably mounted on the bottom support frame 6. The bottom support frame 6 is equipped with a roller 601 on its rear side for easy movement and position adjustment.

[0046] The main support frame 1 includes a vertical support 101, a horizontal support 102, and a mounting bracket 103. The bottom support frame 6 is installed on the rear side of the vertical support 101, the horizontal support 102 is installed on the front side of the vertical support 101, and the mounting bracket 103 is installed on the rear side of the vertical support 101 and above the bottom support frame 6. The storage compartment 2 is detachably installed on the mounting bracket 103 and the vertical support 101 for easy maintenance and replacement. The front end of the horizontal support 102 is connected to the snow sweeper and can rotate flexibly through a hinge structure to ensure the stability and adaptability of the spreader under different road conditions.

[0047] The rollers 601 of the undercarriage frame 6 are made of highly wear-resistant material to ensure stable operation under complex road conditions.

[0048] The dividing plates 301 of the spreading disc 3 are made of high-strength alloy material, which is highly corrosion-resistant and ensures that they will not deform after long-term use. The number of dividing plates 301 can be adjusted according to actual needs, increasing or decreasing the number of dividing plates 301 to adapt to different spreading requirements and improve operational flexibility.

[0049] A vibrating frame 602 is mounted on the front side of the upper end of the support frame 6. A vibrating motor 603 is mounted on the vibrating frame 602. A vibrating plate 604 extends from the right side of the vibrating frame 602. The two vibrating plates 604, on the side opposite to the vibrating motor 603, together form a circular ring plate 605. The circular ring plate 605 is fitted against the outside of the discharge pipe 201. When the vibrating motor 603 is started, the circular ring plate 605 vibrates with the vibrating plate 604, effectively assisting the crushing mechanism, preventing the de-icing agent from clumping, and ensuring smooth discharge. The frequency and intensity of the vibrating motor 603 can be adjusted as needed to further optimize the crushing effect and improve the spreading efficiency.

[0050] A protective plate 606 is installed at the lower end of the vibrating plate 604. The protective plate 606 is made of high-strength material to prevent de-icing agent or salt from splashing upwards during the spreading process, ensuring operational safety. The protective plate 606 has a detachable design for easy cleaning and replacement, ensuring long-term use without damage.

[0051] In addition, the protective plate 606 has a through hole facing the discharge pipe 201 to ensure that the de-icing agent flows out smoothly and avoids accumulation.

[0052] Both sides of the vibrating frame 602 are equipped with vertical baffles 607. The lower end of the vertical baffles 607 extends to the bottom of the support frame 6, forming an effective protective barrier to prevent the de-icing agent from splashing onto the outside of the front of the snowplow, ensuring the cleanliness of the working area and avoiding the waste of de-icing agent or salt.

[0053] A support rod 608 is connected between the mounting bracket 103 and the vibrating plate 604. The support rod 608 is made of high-strength alloy material. After the vibration motor 603 is started, the support rod 608 can effectively transmit vibration, so that the de-icing agent in the storage chamber 2 is vibrated evenly, preventing clumping and ensuring the spreading effect.

[0054] Reference Figure 5 As shown, the lower end face of the circular plate 605 is flush with the lower end face of the discharge pipe 201. The upper end face of the protective plate 606, located below the discharge pipe 201, is provided with an opening and closing component to control the opening and closing state of the lower port of the discharge pipe 201, ensuring that the de-icing agent is spread as needed.

[0055] The opening and closing assembly includes two symmetrical semicircular plates 701. A semicircular hole for the drive shaft 501 to pass through is opened at the center of the two semicircular plates 701. A drive arm 702 is connected to the opposite side of the two semicircular plates 701.

[0056] A bidirectional screw 703 is rotatably mounted on the upper surface of the protective plate 606 via a support base. Two drive arms 702 are threadedly connected to the two ends of the bidirectional screw 703. An operating handle 704 is installed on one end of the bidirectional screw 703. By rotating the operating handle 704, the bidirectional screw 703 is driven to drive the drive arms 702, so that the two semicircular plates 701 open and close synchronously, accurately controlling the output amount and ensuring uniform spreading.

[0057] Furthermore, this application also allows for the installation of a control motor at one end of the bidirectional screw 703 to achieve automated adjustment and improve operational convenience, based on actual operational needs. The control motor is connected to the bidirectional screw 703 and precisely controls the opening and closing of the semi-circular plate 701 through a preset program, adapting to different spreading scenarios.

[0058] The inner wall of storage compartment 2 is equipped with an electric heating layer, and the outer wall is wrapped with insulation material. The working temperature of the electric heating layer is 30-50℃. It is automatically started and stopped based on the feedback data from temperature and humidity sensors to ensure that the de-icing agent maintains optimal fluidity during storage, prevents clumping caused by low temperature, further optimizes the spreading effect, and improves work efficiency.

[0059] The drive mechanism also includes a drive motor 502, which is installed on the outer wall of the storage bin 2. A drive box 503 is provided at the top of the storage bin 2. The output end of the drive motor 502 is rotatably inserted into the drive box 503 and a pulley is installed thereon. The upper end of the drive shaft 501 is also rotatably inserted into the drive box 503 and a pulley is installed thereon. The pulleys are connected by a belt. The drive motor 502 drives the drive shaft 501 to rotate through the belt drive, thereby realizing the operation of the crushing mechanism and the spreading disc 3.

[0060] Example 2:

[0061] Reference Figures 6 to 8 As shown, based on Embodiment 1, the crushing mechanism of this application includes a rotating ring 401 sleeved on a drive shaft 501. The rotating ring 401 rotates with the drive shaft 501. Multiple sets of vertically distributed rotating strips 402 are circumferentially arranged on the outer wall of the rotating ring 401. Multiple steel wire ropes 403 are connected between two vertically distributed rotating strips 402. When the steel wire ropes 403 rotate with the rotating ring 401, they generate shearing force, effectively crushing the agglomerated de-icing agent and ensuring smooth discharge. The steel wire ropes 403 are made of wear-resistant material, suitable for high-intensity operation, and extend the service life of the equipment. The spacing between the steel wire ropes 403 and the axis of the rotating ring 401 is different to improve the shearing effect and cover agglomerated clumps at different locations.

[0062] The bottom of the rotating bar 402 located below is equipped with a scraper 404. The lower surface of the scraper 404 is flush with the lower surface of the discharge pipe 201, and the side wall of the scraper 404 is in close contact with the inner wall of the discharge pipe 201. This ensures that the scraper 404 completely removes residual de-icing agent during rotation, while also ensuring that the de-icing agent is evenly distributed to avoid clogging.

[0063] The rotating bar 402 and the scraper 404 work together to form a high-efficiency crushing and cleaning system.

[0064] A sliding sleeve 405 is slidably fitted on the drive shaft 501 located in the storage compartment 2. The inner wall of the sliding sleeve 405 is provided with a wear-resistant coating to reduce friction loss. The sliding sleeve 405 is tightly fitted with the outer wall of the drive shaft 501 to prevent the de-icing agent in the storage compartment 2 from entering between the sliding sleeve 405 and the drive shaft 501, thus ensuring internal cleanliness.

[0065] A rotating ring 406 is rotatably provided at the lower end of the sliding sleeve 405. A sliding groove is provided on the outer side wall of the drive shaft 501. The rotating ring 406 cooperates with the sliding groove, so that the sliding sleeve 405 rotates synchronously with the drive shaft 501 and can move axially.

[0066] Multiple extension bars 407 are provided circumferentially on the outer side wall of the rotating ring 406. The extension bars 407 correspond one-to-one with the rotating bars 402 above the rotating ring 401. Several steel wire ropes 408 are connected between the vertical extension bars 407 and the rotating bars 402. When the drive shaft 501 rotates, the steel wire ropes 408 are driven to rotate synchronously through the rotating ring 406 and the rotating ring 401, forming a double-layer shearing effect and further enhancing the crushing effect.

[0067] Furthermore, the length of the extension bar 407 is longer than the length of the rotating bar 402, so the steel wire rope 408 is at a certain angle to the axis of the drive shaft 501, which enhances the shearing force and ensures that the clumped de-icing agent is completely broken up.

[0068] A support plate 409 is slidably fitted onto the lower end of the sliding sleeve 405. The support plate 409 is installed on the inner wall of the storage chamber 2. A protrusion is provided inside the sliding sleeve 405. A bidirectional groove 410 is provided on the outer wall of the drive shaft 501 corresponding to the area of ​​the sliding sleeve 405. The protrusion and the bidirectional groove 410 cooperate so that when the drive shaft 501 rotates, the axial movement of the sliding sleeve 405 is achieved through the interaction between the protrusion and the bidirectional groove 410. This drives the rotating ring 406 and the extension bar 407 to move axially, ensuring that the second wire rope 408 is alternately in a tensioned and relaxed state during the up and down movement of the rotating ring 406. This adapts to different agglomerate hardness, improves crushing efficiency, and at the same time, the second wire rope 408 can cover a wider crushing area, avoid dead corners, and ensure uniform crushing of the de-icing agent.

[0069] The top of the sliding sleeve 405 is provided with a sliding plate 411 that is on the same vertical plane as the support plate 409. Both ends of the sliding plate 411 are equipped with elastic support rods 412 with downward telescopic ends. The telescopic ends of the elastic support rods 412 slide through to the bottom of the support plate 409. The elastic support rods 412 provide stable support force to ensure that the sliding plate 411 moves longitudinally on the support plate 409. During the process of the sliding plate 411 moving up and down with the sliding sleeve 405, the elastic telescopic rods can effectively push against the de-icing agent in the storage bin 2 to prevent agglomeration and ensure that the de-icing agent flows smoothly into the discharge pipe 201.

[0070] Two extension strips 413 are symmetrically arranged in the middle of the sliding plate 411. A poking rod 414 is installed at the bottom of the extension strip 413. The poking rod 414 is fixed vertically to the extension strip 413. The end of the poking rod 414 is tapered, which facilitates penetration into the de-icing agent to break up clumps and ensure the fluidity of the de-icing agent. The poking rod 414 is linked to the sliding plate 411 through the extension strip 413 and the elastic telescopic rod. It moves up and down with the sliding plate 411 to achieve all-round disturbance of the de-icing agent in the storage compartment 2. The tapered end design of the poking rod 414 enhances the penetration power and effectively deals with stubborn clumps. The poking rod 414 is made of wear-resistant material and does not stick to the de-icing agent, thus extending its service life.
