Description

Technical Field

[0001] The utility model relates to the field of garbage treatment, in particular to a garbage crushing device for a sweeper vehicle. Background Technique

[0002] With the acceleration of the urbanization process and the continuous increase of the population, the amount of urban garbage generated is also increasing year by year. Garbage treatment has become an important task in modern urban management. As an important tool for maintaining urban environmental sanitation, the performance and efficiency of sweeper vehicles directly affect the effect of garbage treatment and the cleanliness of the urban environment. In the process of garbage treatment by traditional sweeper vehicles, mechanical cleaning and collection methods are usually adopted, but there are some deficiencies in this method. For example, garbage is prone to blockage during the cleaning and collection process, affecting the working efficiency of the sweeper vehicle; when the sweeper vehicle processes some larger or harder garbage, manual intervention is often required, increasing the labor intensity and operation complexity; in addition, the garbage treatment system of traditional sweeper vehicles is prone to secondary pollution during the treatment process, affecting environmental sanitation.

[0003] In response to these problems, some improvement schemes have been proposed in the prior art, but there are still certain limitations. For example, the patent with the publication number CN111636344A discloses a garbage cleaning device for a road sweeper, which transports the garbage collected during the working process of the main brush of the road sweeper to the garbage crushing box for crushing treatment through a transmission mechanism. There are still some deficiencies in the crushing treatment process, such as: 1. Garbage blockage problem: When dealing with some flexible garbage, such as leaves, plastic bags, etc., it is prone to blockage, affecting the normal operation of the sweeper vehicle. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a garbage crushing device for a sweeper vehicle, which solves the problems existing in the prior art. The designed cutting blades are arc-shaped and are tightly fixed on the feeding cutting pipe through cutting grooves, effectively increasing the cutting area and cutting efficiency. The layout and staggered arrangement of the cutting blades further improve the processing capacity of the system, and can quickly and efficiently cut various garbage materials. And through the combined design of the cutting blades and the cutting grooves, a gap guillotine effect is generated, which can cut the garbage into very small pieces, reducing the possibility of garbage accumulation and blockage in the feeding cutting pipe and the conveying pipeline, and ensuring the normal operation of the sweeper vehicle.

[0006] (II) Technical Solutions

[0007] To achieve the above purpose, the utility model provides the following technical solutions: A garbage crushing device for a sweeper vehicle, comprising: a feeding cutting pipe, with connecting mechanisms fixed on both sides of the feeding cutting pipe, and multiple groups of cutting blades are movably connected to the connecting mechanisms;

[0008] The feed cutting pipe is a cylindrical pipe body with both ends open. The left side of the feed cutting pipe is the feed inlet, and the right side is the discharge outlet. Cutting grooves are provided on both sides of the feed cutting pipe. Among them, the feed cutting pipe serves as the main transmission channel of the system. Its cylindrical design and the structure with open ends enable it to effectively guide and convey waste materials. The feed inlet on the left is used to receive waste, and the discharge outlet on the right is used to convey the processed materials to downstream processing equipment or waste collection areas. Cutting grooves are provided on both sides of the feed cutting pipe. The main function of these cutting grooves is to provide space for the cutting tool to enter and operate. The cutting grooves not only define the movement trajectory of the cutting blade but also ensure that the cutting tool can perform cutting operations stably when rotating at high speed.

[0009] Preferably, each cutting blade is arc-shaped, and a cutting edge is provided at one end of the cutting blade, and the cutting edge extends along the arc-shaped edge of the cutting blade. Among them, the cutting edge of the arc-shaped cutting blade extends along the arc-shaped edge, increasing the contact area between the cutting edge and the waste materials, and improving the cutting efficiency and ability. The arc-shaped design enables the cutting blade to better adapt to waste materials of different shapes and densities, thus achieving a wider range of applications. The cutting edge extends uniformly along the blade edge, ensuring the consistency and accuracy during the cutting process, thereby improving the cutting quality. Moreover, the design of the arc-shaped cutting edge helps to evenly distribute the cutting pressure, reducing tool wear and damage and extending the service life of the tool.

[0010] Preferably, the cutting blade is centered in the cutting groove, and the gap between the cutting blade and the cutting groove is less than or equal to 1 mm, and it has the following functions: 1. Precise cutting position control: The cutting blade is centered in the cutting groove, ensuring the stable and precise position of the blade during the cutting process. This position control can improve the cutting accuracy and consistency, ensuring that each cut can achieve the expected effect. 2. Reducing vibration and noise during cutting: A gap of less than or equal to 1 mm can effectively reduce the friction and vibration between the cutting tool and the groove wall during cutting, thereby reducing the noise level during system operation. This is particularly important for waste treatment vehicles in urban environments, reducing interference to surrounding residents. 3. Utilizing the slit guillotine effect to enhance the cutting force: The small gap between the cutting blade and the cutting groove can form a slit guillotine effect, enhancing the cutting force and efficiency of the tool. This physical effect utilizes the high-pressure area where air or fluid is extruded, making the cutting process smoother and more efficient. 4. Extending the service life of the tool: The small gap design helps to reduce the lateral movement and wear of the tool during cutting, thereby extending the service life of the tool and reducing replacement and maintenance costs.

[0011] Preferably, the connecting mechanism includes bearing seats symmetrically fixed on the outer side of the feeding pipe cutter. Bearings are embedded in the bearing seats, and a transmission shaft is movably connected between the bearings. A cutter coupling is fixed on the outer edge of the transmission shaft. Among them, the bearing seat is a component fixed on the outer side of the feeding pipe cutter and is a symmetrically arranged structure. Its main function is to provide a stable support platform for installing and fixing transmission components, while ensuring its firm and stable connection with the feeding pipe cutter. The function of the bearing is to reduce the friction and resistance during the rotation of the transmission shaft, ensuring the smoothness and efficiency of the transmission process. The transmission shaft is responsible for transmitting the driving force to the cutting blade, enabling it to rotate at high speed, thereby realizing the function of garbage cutting and processing. A cutter coupling is fixed on the outer edge of the transmission shaft, and the design of the cutter coupling ensures an effective connection between the transmission shaft and the cutting blade, enabling the cutter to be stably driven and remain stable and efficient during the cutting process.

[0012] Preferably, the cutting grooves are staggered on the outer contour of the feeding pipe cutter. The staggered arrangement of the cutting grooves enables the cutting blades to be arranged in a wider area, effectively enhancing the cutting effect. This layout can effectively handle garbage materials of different shapes and sizes, improving the adaptability and application range of the system.

[0013] Preferably, the overall shape of the cutting groove is arc-shaped, and the size of the cutting groove is one-half of the feeding pipe cutter. The size of the cutting groove being one-half of the diameter of the feeding pipe cutter ensures that the cutting groove can completely cover one side of the feeding pipe cutter. This design takes into account the size of the feeding pipe cutter, enabling the cutting groove to effectively dock with the outer contour of the feeding pipe cutter, ensuring that the cutting tool can fully utilize the entire length of the cutting groove during the cutting operation.

[0014] Preferably, a semi-circular mounting groove is provided at the bottom of the cutting blade, and two cutting blades are symmetrically fixed on the cutter coupling. The semi-circular mounting groove design at the bottom of the cutting blade helps to stably install and fix the cutting blade on the cutter coupling. Two cutting blades are symmetrically fixed on the cutter coupling. This arrangement can balance the load and rotational force of the cutter, reducing imbalance and vibration during the cutting process. Symmetrical fixing also helps to extend the life of the cutter, reducing losses and wear caused by uneven use.

[0015] Preferably, two sets of cutting blades are provided on each side of the feeding pipe cutter. Arranging two sets of cutting blades on each side can significantly increase the cutting capacity of the garbage disposal system of the sweeper.

[0016] Preferably, the angle between each set of cutting blades is 90°. The 90° angle distribution between each set of cutting blades is uniform, which can effectively cover the entire peripheral area of the feeding pipe cutter. This uniform angle setting helps to maximize the cutting range, improving the cutting efficiency and coverage area of the system.

[0017] Preferably, the cutting direction of the left cutting blade is clockwise, and the cutting direction of the right cutting blade is counterclockwise. The left cutting blade rotates clockwise and the right cutting blade rotates counterclockwise. This symmetrical rotation direction can balance the internal forces and reaction forces within the system. The clockwise and counterclockwise cutting methods can reduce the vibration and imbalance of the system, improving the stability and cutting quality during the cutting process.

The design of the tool coupling 24 ensures the effective connection between the transmission shaft and the cutting blade, enabling the tool to be stably driven and maintaining stability and efficiency during the cutting process.

[0029] There are multiple sets of cutting blades 3 movably connected to the connecting mechanism 2; each cutting blade 3 is arc-shaped, and one end of the cutting blade 3 is provided with a cutting edge 31, and the cutting edge 31 extends along the arc edge of the cutting blade 3; the cutting blade 3 is centrally arranged in the cutting groove 13, and the gap between the cutting blade 3 and the cutting groove 13 is less than or equal to 1 mm.

Its surface is coated with hard materials (titanium alloy, titanium nitride), and the rotation speed of the cutting blade is controlled at 700 - 800 RPM.

[0031] The working principle of the present utility model can be specifically divided into the following stages:

[0032] Feeding pipe design: The core component of the system is the feeding pipe cutter 1, which is a cylindrical pipe body with openings at both ends. The left side is the feeding port 11, and the right side is the discharging port 12. Cutting grooves 13 are arranged on both sides of the feeding pipe cutter. These cutting grooves are integrally arc-shaped and have a size of half of the diameter of the feeding pipe cutter.

[0033] Cutting blade configuration: A connecting mechanism 2 is fixed on the outside of the feeding pipe cutter, and multiple sets of cutting blades 3 are installed on the connecting mechanism. The angle between each set of cutting blades is 90°. The left cutting blade rotates clockwise, and the right cutting blade rotates counterclockwise. Each cutting blade is arc-shaped, and a semi-circular mounting groove 32 is provided at the bottom and is symmetrically fixed on the tool coupling 24.

[0034] Preparation work: First, the whole device is installed in the cleaning vehicle. The drive shafts 23 on both sides of the device are externally connected to a drive motor. Garbage is sucked into the cleaning vehicle by high-pressure air, and through the cavity preset at the bottom of the front section of the device, stones and metals will directly fall into the collection box in the cleaning vehicle due to their large density, and soft garbage such as leaves and plastic bags will enter the pipe cutter through the feeding port 11.

[0035] Cutting process and effect: When the garbage enters the interior from the feed inlet 11, it is first captured and positioned by the cutting edge 31 of the cutting blade 3. The cutting blade 3 rotates at high speed and breaks in the clockwise or counterclockwise direction. The cutting edge 31 extends along the arc-shaped edge of the cutting groove 13. The small gap between the cutting blade 3 and the cutting groove 13 utilizes the slit guillotine effect to enhance the cutting force and effect of the cutting edge. This effect enables the cutting edge to cut deeper into the garbage material, improving the cutting efficiency and accuracy. After cutting, the cut material is discharged through the discharge outlet 12 to complete the garbage treatment process.

[0036] In summary, this garbage treatment system for a cleaning vehicle realizes an efficient, precise, and stable garbage treatment process through the design optimization between the cutting blade and the cutting groove and the slit guillotine effect, and is applicable to various application scenarios of garbage cleaning and treatment in urban environments.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
