Description

Technical Field

[0001] This utility model relates to the field of garbage collection vehicle technology, specifically to a rapid material shoveling structure for a garbage collection vehicle. Background Technology

[0002] Garbage collection trucks are common sanitation vehicles or garbage trucks in municipalities. They are indispensable special vehicles in the urban sanitation system, mainly used to collect, compress, and transfer domestic waste and some commercial waste. They have a bucket structure at the rear for loading garbage into the truck.

[0003] In the prior art, Chinese Patent Application No. CN201210397190.6 discloses a material shoveling device for a rear-loading compactor garbage truck, used on a rear-loading compactor garbage truck containing a stuffer. It includes a tipping mechanism and a bucket. The bucket includes a shovel opening, two sides, a bottom surface, a rear surface, and a discharge port. The outer side of the rear of the bucket is located on the tipping mechanism, which is located on the lower part of both sides of the stuffer. It also includes pulleys and pulley seats. The pulley seats are symmetrically arranged on the lower part of both sides of the bucket. The pulleys are mounted on the pulley seats, and the axis of the pulleys is located on the outer side of the bottom surface of the bucket.

[0004] For example, in the prior art, Chinese patent application number CN202210010250.8 discloses a garbage sweeping or material collection device, including a collection shovel, a movable link, a hanging ear, a circulating chain, and a circulating track. The collection shovel is connected to the movable link, the movable link is connected to the hanging ear, and the hanging ear is connected to the circulating chain. The circulating chain moves along the circulating track, driving the collection shovel to move up and down and back and forth along the circulating track, thereby completing the cyclical operation process of the collection shovel sweeping and collecting garbage, lifting garbage, tipping and dumping garbage into the garbage bin, and descending empty. When the collection shovel is at the bottom, it moves backward along the circulating track in the opposite direction to the vehicle body, and the speed is equal to the forward speed of the vehicle body, so that the collection shovel is stationary on the ground at the bottom to improve sweeping efficiency.

[0005] For example, in the prior art, Chinese patent application number CN202120405145.5 discloses a pusher assembly for a compression garbage truck, including a shovel body, a power pusher arm and a buffer arm installed on the shovel body, the buffer arm being buffered connected to the shovel body, the shovel body including a bottom plate, a first support beam and a second support beam installed on both sides of the bottom plate, the pusher plate and the second support beam being set at an angle, the power pusher arm being pushed by a hydraulic cylinder, the buffer arm including a buffer hydraulic cylinder and a spring disposed between the buffer hydraulic cylinder and the first support beam, the first support beam being configured as several vertical steel sections, the first support beams located on both sides of the bottom plate corresponding to two power pushers, the remaining first support beams corresponding to buffer arms, the power pusher arm being hinged to the first support beam, the vertical height of the hinge point being lower than the vertical height of the connection point between the spring and the first support beam.

[0006] Based on the above information, it can be seen that existing garbage trucks generally dump garbage into the truck by tilting the bucket. However, in actual use, the garbage contains a certain amount of moisture, and damp garbage is prone to sticking to the inner wall of the bucket, resulting in incomplete dumping and requiring manual cleaning, which affects efficiency. Utility Model Content

[0007] The purpose of this utility model is to provide a rapid material shoveling structure for a garbage truck, so as to solve the problem of incomplete garbage dumping mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rapid material shoveling structure for a garbage truck, comprising a fixed frame fixedly installed at the rear of the garbage truck body, a shovel bucket installed at the lower end of the fixed frame, and the shovel bucket being rotatably installed to the fixed frame via a connecting shaft, a connecting plate rotatably installed on the outer side of the fixed frame, and the connecting plate being connected to the shovel bucket via a mounting rod, a vibration mechanism being provided between the mounting rod and the shovel bucket, and a telescopic hydraulic cylinder being rotatably installed between the connecting plate and the garbage truck body, a striking block being rotatably installed on the inner side of the fixed frame, and the striking block being driven by a drive motor fixedly installed on the outer side of the fixed frame; a hollow odor-neutralizing box is fixedly installed on the outer back of the shovel bucket.

[0009] Preferably, the outer surface of the striking block is provided with a protrusion structure arranged at equal intervals, and the striking block is in corresponding contact with the top of the shovel hopper when it is retracted;

[0010] When the striking block rotates, it causes the external protrusion structure to intermittently strike the shovel bucket, thereby causing the shovel bucket to vibrate.

[0011] Preferably, the vibration mechanism includes a limiting ring fixedly installed on the outer surface of the hopper, and the mounting rod is inserted into the inner side of the limiting ring. A first spring is fixedly installed between the mounting rod and the inner wall of the limiting ring. The mounting rod can move inside the limiting ring, and when the mounting rod moves, it squeezes the first spring inside the limiting ring, thereby improving the vibration effect by utilizing the elasticity of the spring.

[0012] Preferably, a movable scraper is installed at the bottom inner side of the hopper, and the movable scraper and the hopper form a left-right sliding structure;

[0013] The vibration drives the movable scraper to move synchronously, thereby further improving the cleaning effect of residual waste.

[0014] Preferably, the rod-shaped structure on the side of the movable scraper slides through the hopper, and a second spring is provided on the outside of the rod-shaped structure on the side of the movable scraper.

[0015] The second spring can provide a cushioning effect for the moving scraper, maintaining the stability of vibration.

[0016] Preferably, a connecting pipe extending into the hopper is fixedly installed on the side of the odor-eliminating box, and a negative pressure head is fixedly installed at the top of the connecting pipe;

[0017] The air drawn in by the negative pressure head is transported into the deodorizing chamber through the connecting pipe to achieve air circulation.

[0018] Preferably, a delivery pump connected to a connecting pipe is fixedly installed inside the odor removal box, and a filter cotton containing activated carbon is installed inside the odor removal box. An exhaust pipe is fixedly installed on the upper surface of the odor removal box. The activated carbon material contained in the filter cotton can absorb odors, ultimately achieving the purpose of odor removal.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the rapid material shoveling structure of this garbage truck adopts a novel structural design, the specific details of which are as follows:

[0020] 1. The extension of the telescopic cylinder pushes the connecting plate, causing the connecting plate to drive the shovel bucket to rotate around the connecting shaft, thereby causing the shovel bucket to flip and dump the garbage into the garbage truck compartment. When the front end of the shovel bucket fully contacts the striking block, the drive motor is turned on to drive the striking block to rotate, causing the striking block to strike the shovel bucket and generate vibration, shaking off the garbage attached to the inner wall of the shovel bucket.

[0021] Furthermore, during the vibration process, the shovel bucket and the mounting rod move relative to each other. At this time, the mounting rod squeezes the first spring on the inner wall of the limiting ring, and the elasticity of the first spring provides a better vibration effect.

[0022] Furthermore, during the vibration of the hopper, the internal movable scraper also vibrates left and right under the action of the second spring, thereby scraping away the sheet-like garbage (such as paper, garbage bags, etc.) attached to the inner wall of the hopper to achieve a better cleaning effect.

[0023] 2. During the operation of the device, the conveying pump is turned on. The negative pressure is generated at the negative pressure head through the connecting pipe connected to the conveying pump, thereby sucking the gas in the shovel hopper and garbage truck compartment into the odor removal box. The odor removal box uses filter cotton to filter and adsorb the odor (the filter cotton contains activated carbon particles, which are used to remove odors). Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please see Figures 1-2 In order to achieve the purpose of shoveling garbage into the truck, this embodiment provides the following technical solution, which specifically discloses: a fixed frame 2 fixedly installed at the rear of the garbage truck compartment 1, a shovel hopper 3 installed at the lower end of the fixed frame 2, and the shovel hopper 3 is rotatably installed with the fixed frame 2 through a connecting shaft 4, a connecting plate 5 is rotatably installed on the outside of the side of the fixed frame 2, and the connecting plate 5 is connected to the shovel hopper 3 through an installation rod 9, a vibration mechanism is provided between the installation rod 9 and the shovel hopper 3, and a telescopic cylinder 6 is rotatably installed between the connecting plate 5 and the garbage truck compartment 1.

[0036] When using the device, the staff first pours the garbage from the trash can into the shovel hopper 3, and then activates the telescopic cylinder 6. At this time, the telescopic cylinder 6 extends and pushes the connecting plate 5 to rotate. During the rotation of the connecting plate 5, the shovel hopper 3 rotates around the connecting shaft 4 through the mounting rod 9, and finally flips the shovel hopper 3 to pour the garbage into the garbage truck compartment 1.

[0037] Example 2

[0038] Please see Figures 3-7 In order to achieve the purpose of shaking off the garbage attached to the inner wall of the hopper 3, this embodiment provides the following technical solution, which specifically discloses: a striking block 7 is rotatably installed on the inner side of the fixed frame 2, and the striking block 7 is driven by a drive motor 8 fixedly installed on the outside of the fixed frame 2. The outer surface of the striking block 7 is provided with a protrusion structure arranged at equal intervals, and the striking block 7 is in corresponding contact with the top of the hopper 3 when it is retracted. The vibration mechanism includes a limiting ring 10 fixedly installed on the outer surface of the hopper 3, and an installation rod 9 is inserted into the inner side of the limiting ring 10. A first spring 11 is fixedly installed between the installation rod 9 and the inner wall of the limiting ring 10. A movable scraper 12 is installed at the bottom of the inner side of the hopper 3, and the movable scraper 12 and the hopper 3 form a left and right sliding structure. The rod-shaped structure on the side of the movable scraper 12 slides through the hopper 3, and a second spring 13 is provided on the outside of the rod-shaped structure on the side of the movable scraper 12.

[0039] When the hopper 3 flips to contact the striking block 7 at the front end (i.e., when the hopper 3 flips to its maximum angle), the drive motor 8 is turned on. The drive motor 8 drives the striking block 7 to rotate, causing the protruding structure on the outer surface of the striking block 7 to strike the front end of the hopper 3, generating vibration. This vibration shakes off the garbage attached to the inner wall of the hopper 3. During this process, the mounting rod 9 moves inside the limiting ring 10. At this time, the mounting rod 9 compresses the first spring 11 inside the limiting ring 10. Under the elastic action of the first spring 11, the overall vibration effect of the hopper 3 is improved, thereby achieving a better shaking effect. In addition, during the vibration of the hopper 3, the second spring 13 will drive the movable scraper 12 inside it to move synchronously (the rod-like structure on the outside of the movable scraper 12 slides through the hopper 3 to support the movable scraper 12). The movable scraper 12 is used to clean off the sheet-like garbage (such as paper, garbage bags, etc.).

[0040] Example 3

[0041] Please see Figure 8In order to prevent odors from spreading outward, this embodiment provides the following technical solution, which specifically discloses: a hollow odor-eliminating box 14 is fixedly installed on the outer side of the back of the hopper 3, a connecting pipe 15 extending into the hopper 3 is fixedly installed on the side of the odor-eliminating box 14, and a negative pressure head 16 is fixedly installed at the top of the connecting pipe 15. A delivery pump 17 connected to the connecting pipe 15 is fixedly installed inside the odor-eliminating box 14, and a filter cotton 19 containing activated carbon is installed inside the odor-eliminating box 14. An exhaust pipe 18 is fixedly installed on the upper surface of the odor-eliminating box 14.

[0042] During the use of the device, the conveying pump 17 inside the deodorizing box 14 is turned on. At this time, the negative pressure is generated at the position of the negative pressure head 16 under the action of the connecting pipe 15 connected to the conveying pump 17. The negative pressure is used to draw the gas in the shovel hopper 3 and the garbage truck compartment 1 into the deodorizing box 14. At this time, the filter cotton 19 inside the deodorizing box 14 is used to remove the odor from the gas (the filter cotton 19 contains activated carbon particles, which adsorb odors). The deodorized gas is discharged through the exhaust pipe 18.
