Description

Technical Field

[0001] This utility model relates to the technical field of sweeper trucks, specifically to a crushing device for sweeper trucks. Background Technology

[0002] As a core piece of equipment for modern urban sanitation and road cleaning, the sweeper truck integrates high-pressure washing and vacuum sweeping functions, offering a series of significant advantages that far surpass traditional single sweeping or washing operations in terms of efficiency and effectiveness. It not only removes ordinary garbage but also effectively removes adhering dirt, dust, mud, and oil stains from the road surface, restoring the road to its original color and significantly improving the visual quality of the road and the level of environmental hygiene.

[0003] Chinese patent application CN202021794772.4, entitled "A Crushing Device for a Sweeper Truck," discloses a crushing device for a sweeper truck. It optimizes the existing suction cup body by adding a crushing device. The blades of this crushing device rotate at high speed within the waste flow channel, forcibly throwing debris such as leaves towards the rear, thus improving the suction cup's working efficiency. The cutting blades of this crushing device can extend into the waste flow channel of the suction cup body to crush the sucked-in waste, allowing the waste inside the suction cup body to be quickly transported to the recycling bin. This crushing device enables effective sweeping of roads with a large amount of leaves and the recycling of ground waste.

[0004] However, the above-mentioned patent still has the following shortcomings. Although the rotating blades have a certain crushing effect on the garbage entering the garbage flow channel, they also have the effect of pushing the garbage to move during the crushing process. This results in the garbage only being subjected to the force of the blades during crushing, and not being subjected to the clamping force. This will greatly reduce the crushing effect, and some garbage will not be crushed. Although the existing technology adds blades to crush the garbage, it only reduces the probability of blockage. Some garbage that is too large will still not be crushed. Therefore, it is necessary to design a crushing device for sweeper trucks. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem that some waste is still not crushed in the existing technology.

[0006] To achieve the above objectives, this utility model provides a crushing device for a sweeper truck, comprising: a suction cup body with a garbage flow channel and a crushing unit communicating with the interior of the suction cup body. The crushing unit includes a housing fixedly mounted on the top of the suction cup body, a horizontal drive shaft rotatably mounted on the housing, a plurality of crushing blades uniformly mounted on the drive shaft and capable of rotating into the garbage flow channel, an mounting arm fixedly mounted on the inner wall of the housing away from the suction port of the garbage flow channel and parallel to the drive shaft, and a plurality of intercepting arms located at the garbage flow channel and spaced apart along the length of the mounting arms and staggered with the corresponding crushing blades. When the drive shaft drives the crushing blades to rotate, it passes between two adjacent intercepting arms.

[0007] Preferably, the mounting arm is assembled onto the housing by a plurality of first mounting bolts, and a plurality of intercepting arms are fixedly welded onto the mounting arm.

[0008] Preferably, at least one side wall of the mounting arm is recessed with a mounting groove in the same length direction, and the intercepting arm is provided with a positioning block that matches the mounting groove.

[0009] Preferably, the crushing unit further includes a motor mounted on the housing and connected to the drive shaft, and a plurality of cutter discs spaced apart along the length of the drive shaft and coaxially mounted on the drive shaft. Each crushing blade is mounted on the corresponding cutter disc by a plurality of second mounting bolts.

[0010] Preferably, the interceptor arm includes a first vertical rod whose lower end is fixedly connected to the mounting arm, an inclined rod whose top end is fixedly connected to the top of the first vertical rod, and a second vertical rod whose top end is connected to the lower end of the inclined rod, wherein the lower end of the inclined rod is inclined toward the drive shaft.

[0011] Preferably, a reinforcing rod connected to the middle of the inclined rod is fitted on the lower end of the first vertical rod.

[0012] Preferably, the reinforcing rod is fixedly fitted with a mounting part that is welded and fixed to the mounting arm.

[0013] According to the above technical solution, the beneficial effects of the crushing device for a sweeper truck provided by this utility model in use are as follows: The intercepting arms control the size of the waste passing through the waste flow channel, preventing excessively large waste from entering and causing blockages. Larger waste gets stuck between the intercepting arms. As the shredder rotates, it passes between adjacent intercepting arms, thus shredding the waste stuck between them. The intercepting arms act as a grip on the stuck waste, facilitating the shredder's crushing action and ensuring that only small-sized waste is drawn into the waste flow channel, preventing blockages.

[0014] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0019] like Figure 1-4As shown, a sweeper truck crushing device includes: a suction cup body 2 with a garbage flow channel 1 and a crushing unit communicating with the inside of the suction cup body 2. The crushing unit includes a housing 3 fixedly mounted on the top of the suction cup body 2, a horizontal drive shaft 4 rotatably mounted on the housing 3, a plurality of crushing blades 5 uniformly mounted on the drive shaft 4 and capable of rotating into the garbage flow channel 1, an mounting arm 6 fixedly mounted on the inner wall of the housing 3 away from the suction port of the garbage flow channel 1 and parallel to the drive shaft 4, and a plurality of intercepting arms 7 located at the garbage flow channel 1 and spaced along the length of the mounting arm 6 and staggered with the corresponding crushing blades 5. When the drive shaft 4 drives the crushing blades 5 to rotate, they pass between two adjacent intercepting arms 7.

[0020] In the above technical solution, during use, a negative pressure is generated inside the suction cup 2, which draws the garbage into the garbage flow channel. The drive shaft 4 drives several shredders 5 to rotate, thus initially shredding the garbage. The intercepting arms 7 control the size of the garbage passing through the garbage flow channel 1, preventing excessively large garbage from entering and causing blockage. At this time, excessively large garbage will be stuck between several intercepting arms 7. When the shredders 5 rotate, they will pass between two adjacent intercepting arms 7, thus shredding the garbage stuck between the intercepting arms 7. At this time, the intercepting arms 7 act as a grip on the stuck garbage, which is conducive to the shredders 5 shredding the garbage, thus ensuring that only small-volume garbage is drawn into the garbage flow channel 1, avoiding blockage problems.

[0021] In a preferred embodiment of the present invention, the mounting arm 6 is assembled onto the housing 3 by a plurality of first mounting bolts, and a plurality of intercepting arms 7 are fixedly welded onto the mounting arm 6.

[0022] In the above technical solution, several interceptor arms 7 are fixedly welded to the mounting arm 6 to prevent the interceptor arms 7 from falling off during use. By loosening and removing the first mounting bolt, the entire mounting arm 6 and interceptor arms 7 can be replaced or disassembled for maintenance.

[0023] In a preferred embodiment of the present invention, at least one side wall of the mounting arm 6 is recessed with a mounting groove 8 in the same length direction, and the intercepting arm 7 is provided with a positioning block that matches the mounting groove 8.

[0024] In the above technical solution, although the interceptor arm 7 is fixedly welded to the mounting arm 6, the positioning block and mounting groove 8 can quickly position the interceptor arm 7, which facilitates welding.

[0025] In a preferred embodiment of the present invention, the crushing unit further includes a motor 9 mounted on the housing 3 and connected to the drive shaft 4, and a plurality of cutter discs 10 spaced apart along the length of the drive shaft 4 and coaxially mounted on the drive shaft 4. Each crushing blade 5 is mounted on the corresponding cutter disc 10 by a plurality of second mounting bolts.

[0026] In the above technical solution, the motor 9 drives the drive shaft 4 to rotate, which in turn drives the crushing blades 5 to rotate through several cutter discs 10. The crushing blades 5 on the cutter discs 10 can be replaced through the second mounting bolt.

[0027] In a preferred embodiment of the present invention, the intercepting arm 7 includes a first vertical rod 11 whose lower end is fixedly connected to the mounting arm 6, an inclined rod 12 whose top end is fixedly connected to the top of the first vertical rod 11, and a second vertical rod 13 whose top end is connected to the lower end of the inclined rod 12. The lower end of the inclined rod 12 is inclined toward the drive shaft 4.

[0028] In the above technical solution, large-volume waste will mainly be stuck between the inclined rods 12 and the second vertical rods 13 of the two adjacent mounting arms 6, while the crushing blade 5 will first enter between the two adjacent second vertical rods 13 when it rotates, and then pass between the two adjacent inclined rods 12.

[0029] In a preferred embodiment of the present invention, a reinforcing rod 14 connected to the middle of the inclined rod 12 is fitted on the lower end of the first vertical rod 11.

[0030] In the above technical solution, the reinforcing rod 14 can improve the strength of the intercepting arm 7.

[0031] In a preferred embodiment of this utility model, the reinforcing rod 14 is fixedly fitted with a mounting part 15 that is welded and fixed to the mounting arm 6.

[0032] In the above technical solution, the mounting part 15 can be directly welded to the mounting arm 6, thereby improving the connection strength between the intercepting arm 7 and the mounting arm 6.

[0033] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0035] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
