Description

Technical Field

[0001] The invention relates to the technical field of mixer truck cleaning, in particular to a cleaning device for a self-loading mixer truck. Background Art

[0002] A concrete mixer truck, or mixer truck, is a special truck used to transport ready-mixed concrete for construction. Due to its appearance, it is often called a snail truck. The truck is equipped with a cylindrical mixing drum to carry the mixed concrete. During the transportation process, the mixing drum will always keep rotating to ensure that the transported concrete will not solidify. Cement mixer trucks play a very important role in urbanization construction.

[0003] In the prior art, a Chinese patent with publication number "CN110496838A" discloses a cement mixer tank cleaning device. A water distribution pipe is arranged on the top of the mixing tank. The water distribution pipe sprays water to clean the tank body through a cleaning nozzle, and the bottom of the tank body is brushed with a cleaning brush. The cleaning is convenient and effective, and the environment is effectively protected, urban dust pollution is reduced, and the problem that the mixing tank is often covered with dust, polluting the environment, and affecting the image of the city is solved because the mixer truck often travels between the construction site and the city.

[0004] In the working environment of the existing mixer truck, dust is easily accumulated on the surface of the mixing tank, and after the mud is discharged, some mud is often left on the discharge plate, which is difficult to be completely discharged.

The tooth block 34 meshes with the driven gear 35, and the position of the driven gear 35 is on the outside of the positioning plate 7. The side end surface of the lifting plate 32 is fixedly installed with a T-shaped slider 36. The side end surface of the mounting frame plate 5 is provided with a slide groove 37 used in conjunction with the T-shaped slider 36. The T-shaped slider 36 is slidably connected with the slide groove 37. When the T-shaped slider 36 slides in the slide groove 37, the lifting plate 32 will synchronously drive the L-shaped plate 33 in the process of lifting and lowering to ensure that it will not be displaced. The cross-sectional shape of the driving rod 29 is T-shaped to ensure that the pulling plate 30 will not be detached when working.

[0037] In this embodiment, the output shaft 22 is driven to rotate by the driving motor 21 in the driving assembly, and the output shaft 22 uses the driving roller 24 to cooperate with the driving groove 27 on the swing plate 26, and uses the driving shaft 25 to make the shunt pipe 13 in a swinging state.

Embodiment 3

[0038] On the basis of the second embodiment, a drainage component is provided on the driving component, through which the mud discharged from the mixing tank 2 can accurately fall onto the discharge plate 3, and the drainage component includes a U-shaped frame plate 40 fixedly mounted on the mounting frame plate 5 and a swinging tooth plate 41 fixedly mounted on the driving shaft 25, a bearing 42 is fixedly mounted on the U-shaped frame plate 40, a diverter rod 43 is fixedly mounted on the bearing 42, a diverter blade 44 is fixedly mounted on one end of the diverter rod 43, an auxiliary gear 45 is fixedly mounted on the other end of the diverter rod 43, and the swinging tooth plate 41 is meshed with the auxiliary gear 45, wherein the diverter blade 44 is relatively small in size, and the position of the diverter blade 44 is at the position where the mud falls, and when the mud continues to fall, the diverter blade 44 will not break up the mud, thereby avoiding dirt in the working area and the mixer truck.

[0039] In this embodiment, when the mixing tank 2 is discharging material, the valve 46 is closed, and the driving shaft 25 will synchronously drive the rocking gear plate 41 to rotate during rotation. The rocking gear cooperates with the auxiliary gear 45, and the auxiliary gear 45 drives the diverter blade 44 on the diverter rod 43 to swing back and forth. When the mixing tank 2 discharges the mud onto the discharge plate 3, the diverter blade 44 is used to swing inside the mud, so that the falling mud is in a uniform falling state. The uniformly falling mud will fall accurately on the discharge plate 3, effectively preventing the mud from overflowing on the discharge plate 3, and keeping the working area and the mixer truck clean.

[0040] Working principle:

[0041] When in use, the clean water in the water tank 6 is passed into the drain pipe 10 through the water pump 8 using the input pipe 9, and the clean water in the drain pipe 10 is passed into the diversion pipe 13 through the first telescopic hose 11, and part of the clean water in the diversion pipe 13 is sprayed onto the mixing tank 2 through the first spray head 14, and the other part of the clean water is passed into the guide pipe 16 through the connecting pipe 18 and the second telescopic hose 19, and the clean water in the guide pipe 16 is sprayed onto the discharge plate 3 through the second spray head 17, and the surface of the mixing tank 2 and the surface of the discharge plate 3 are cleaned by the clean water, so as to effectively prevent dust from floating and mud residue during the operation of the mixer truck;

[0042] The output shaft 22 is driven to rotate by the driving motor 21, and the output shaft 22 cooperates with the driving groove 27 on the swing plate 26 by using the driving roller 24, and the diverter pipe 13 is put into a swinging state by using the driving shaft 25. At the same time, the output shaft 22 drives the driving rod 29 on the circular plate 28 to rotate when rotating, and the driving rod 29 drives the gear block 34 on the L-shaped plate 33 to reciprocate up and down through the pulling plate 30, and then the gear block 34 cooperates with the driven gear 35, so that the guide pipe 16 is in a swinging state. When the diverter pipe 13 and the guide pipe 16 are in swinging at the same time, the cleaning water sprayed by the first spray head 14 and the second spray head 17 can better contact with the mixing tank 2 and the discharge plate 3, thereby improving the cleaning effect of the mixing tank 2 and the discharge plate 3;

[0043] When the mixing tank 2 is discharging, the valve 46 is closed, and the clean water in the diverter pipe 13 will not enter the diverter pipe 13. The driving shaft 25 will synchronously drive the swing gear plate 41 to rotate when rotating. The swing gear cooperates with the auxiliary gear 45, and the auxiliary gear 45 drives the diverter blade 44 on the diverter rod 43 to swing back and forth. When the mixing tank 2 discharges the mud onto the discharge plate 3, the diverter blade 44 is used to swing inside the mud, so that the falling mud is in a uniform falling state. The uniformly falling mud will accurately fall on the discharge plate 3, effectively preventing the mud from overflowing on the discharge plate 3, and keeping the working area and the mixer truck clean.

[0044] When the L-shaped plate 33 is in a reciprocating lifting and lowering state, the connecting plate 38 on the L-shaped plate 33 will be lifted and lowered reciprocatingly at the same time, and then the knocking block 39 on the connecting plate 38 will be used to knock the bottom of the discharge plate 3 back and forth. The knocking force generated by the knocking block 39 will cause the mud on the discharge plate 3 to be quickly discharged. At the same time, when the clean water cleans the discharge plate 3, the mud flushed by the clean water will also quickly slide off the discharge plate 3.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
