Description

Technical Field

[0001] The invention relates to the technical field of bucket cleaning, and in particular to a bucket cleaning device for a mining truck. Background Art

[0002] When a mine car is transporting minerals, various dust, mud, etc. are easily attached to the body of the mine car, and the mine car needs to be cleaned. In the prior art, a water spray cleaning device is generally set on the door head frame to clean the surface of the mine car. At the same time, a water spray cleaning device can also be set on the top to clean the inside of the car bucket. The surface dust is easily washed off. However, when the inside of the car bucket is filled with minerals, some minerals and attachments mixed with mud and the like are adhesive, especially under the action of gravity extrusion, attached to the inner wall of the car bucket. Simple high-pressure direct flushing sometimes cannot quickly flush the attachments, or repeated long-term flushing is required to complete the cleaning of the inner wall of the car bucket, which is time-consuming and labor-intensive, with low flushing efficiency and a lot of water resources waste. The cost of filtering and recycling the wastewater containing minerals after flushing is high, the filtering equipment is complicated, the equipment is easily damaged, the economic benefit is low, and it is not convenient for recycling.

[0003] In the prior art, the problem of low efficiency and waste of water resources in flushing the minerals attached to the inner wall of the truck bed needs to be solved. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a mining truck bucket cleaning device in view of the above-mentioned technical deficiencies, which solves the problems of low efficiency and waste of water resources in flushing minerals attached to the inner wall of the bucket in the prior art.

[0005] The technical solution adopted by the present invention is: to provide a mining truck bucket cleaning device, including a top frame located above the vehicle bucket, characterized in that it also includes:

[0006] A hanging seat is horizontally movable relative to the top frame and is arranged to be lifted and lowered. After the hanging seat moves horizontally, it approaches or moves away from the inner wall of the truck bucket;

[0007] A rotating frame, rotatably arranged at the lower end of the suspension seat;

[0008] A mounting frame is rotatably arranged on the rotating frame, and the mounting frame rotates on the hanging seat following the rotating frame, and the rotation axis direction of the mounting frame on the rotating frame is perpendicular to the rotation axis direction of the rotating frame on the hanging seat, and is used to make the mounting frame swing up and down and rotate horizontally relative to the truck bucket, and the mounting frame follows the hanging seat to rise and fall in the truck bucket;

[0009] A cleaning nozzle, arranged at the lower end of the mounting frame, connected to an external water source, and used for spraying water onto the inner wall of the bucket;

[0010] A recovery box is arranged at the lower side of the mounting frame and below the cleaning nozzle. The upper end of the recovery box is provided with a recovery port for recovering water and solid particles splashed from the inner wall of the bucket.

[0011] To further optimize the technical solution, a plurality of first water spray holes are provided on one side of the cleaning nozzle, the water outlet direction of the first water spray holes is inclined and tilted downward toward the inner wall of the bucket, and the first water spray holes are located directly above the recovery port.

[0012] Further optimizing the technical solution, the cleaning nozzle is reciprocatingly slidably arranged on the mounting frame, and the sliding direction of the cleaning nozzle is perpendicular to the water outlet direction of the first water spray hole, and further comprising:

[0013] The reciprocating drive mechanism is arranged on the mounting frame and is used for driving the cleaning nozzle to slide reciprocally.

[0014] To further optimize the technical solution, the cleaning nozzle also has a plurality of second water spray holes, the second water spray holes are respectively arranged on both sides of the first water spray hole, and the water outlet direction of the second water spray holes points to the inner wall of the truck bed.

[0015] Further optimization of this technical solution also includes:

[0016] There are several stirring plates, which are arranged in an array at the lower end of the cleaning nozzle in sequence, and the lower end of the stirring plate extends to the lower part of the recovery box, and the lower part of the stirring plate reciprocates in the lower part of the recovery box.

[0017] To further optimize the technical solution, a vertical side wall of the recovery box close to the first water spray hole is inclined, and the upper end of the inclined vertical side wall is closer to the inner wall of the truck bucket than the lower end.

[0018] Further optimization of this technical solution also includes:

[0019] A sliding seat, slidably arranged on the top frame;

[0020] A translation seat, horizontally movable and arranged on the slide seat;

[0021] A linear drive mechanism is arranged at the lower end of the translation seat, and a moving end of the linear drive mechanism is arranged at the upper end of the suspension seat;

[0022] Wherein, the sliding seat and the translation seat are used to drive the hanging seat to move horizontally, and the linear driving mechanism is used to drive the hanging seat to move up and down.

[0023] Further optimization of this technical solution also includes:

[0024] A rotating motor, arranged on the suspension seat, for driving the rotating frame to rotate;

[0025] The swing motor is arranged on the rotating frame and is used for driving the mounting frame to swing up and down.

[0026] The beneficial effects of the present invention are:

[0027] 1. When the cleaning nozzle moves up and down in the bucket to wash the inner wall of the bucket, the recycling box can collect the wastewater and solid particles splashed from the inner wall of the bucket. When the recycling box moves to the top of the bucket with the hanging seat, the recycling box swings up and down with the mounting frame, which can make the recycling box flip down and tilt, and use the wastewater and solid particles recovered inside to spray the inner wall of the bucket from above, which plays a role of preliminary spraying and wetting. At the same time, the solid particles adhere to the surface of the attachments on the inner wall. The wastewater mixed with particles is directly sprayed on the inner wall of the bucket, and there is no need to filter and remove impurities for reuse. The structure is simple, and it will not cause equipment damage. Both wastewater and solid particles are reused, and the cleaning efficiency is improved.

[0028] 2. Preliminary spray wetting can directly wash off some external attachments with poor adhesion, reducing the obstruction of high-pressure washing. High-pressure washing directly acts on the surface of attachments that are not easy to fall off, saving water resources. At the same time, waste water penetrates into the interior of the attachments, making them partially soft in advance, making it easier to wash away the attachments more quickly during washing.

[0029] 3. The surface of the attachment is bumpy and uneven, and solid particles tend to stay on the upward surface of the attachment, which is different from the properties of the integrated attachment itself. When the integrated attachment is subjected to high-pressure impact, the attachment body gradually breaks into small pieces or particles, and finally splashes out directly (under the outward force, the attachment will gradually disintegrate and splash out directly under the action of external force. Part of the splashed wastewater, particles and small pieces will be collected by the recycling box); the particles that remain on the surface of the attachment after spraying from the recycling box are not an integrated structure with the attachment. When subjected to high-pressure impact, they are more likely to follow the high-pressure water flow to impact the surface of the attachment, and finally splash out. There is an additional process of following the high-pressure water flow impact, and the surface of the particles is irregular, which is more likely to cause the attachment to break, thereby improving the flushing efficiency.

DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0040] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance. The explanation is based on the longer direction of the mine car as the front and rear direction. The top frame can be suspended or supported off the ground by columns. This is a prior art and depends on the site environment.

[0042] like Figure 1-7As shown, a mining truck bucket cleaning device includes a top frame 101 located above the vehicle bucket, and also includes: a suspension seat 105, which is horizontally movable and lifting relative to the top frame 101, and the suspension seat 105 moves closer to or away from the inner wall of the bucket after horizontal movement; a rotating frame 106, which is rotatably arranged at the lower end of the suspension seat 105; a mounting frame 2, which is rotatably arranged on the rotating frame 106, and the mounting frame 2 rotates on the suspension seat 105 following the rotating frame 106, and the rotation axis direction of the mounting frame 2 on the rotating frame 106 is perpendicular to the rotation axis direction of the rotating frame 106 on the suspension seat 105, which is used to make the mounting frame 2 swing up and down and rotate horizontally relative to the bucket, and the mounting frame 2 follows the suspension seat 105 to rise and fall in the bucket; a cleaning nozzle 3, which is arranged at the lower end of the mounting frame 2 and is connected to an external water source, and is used to spray water to the inner wall of the bucket; a recovery box 4, which is arranged on the lower side of the mounting frame 2 and is located below the cleaning nozzle 3, and the upper end of the recovery box 4 has a recovery port 401, which is used to recover water and solid particles splashed from the inner wall of the bucket.

[0043] When in use, the mounting frame 2 is installed on the hanging seat 105 through the rotating frame 106. Finally, the mounting frame 2 can be lifted and lowered, moved horizontally forward, backward, left and right, and rotated on the horizontal plane, so that the cleaning nozzle 3 can move up and down to clean the inner wall of the truck bucket. After the cleaning nozzle 3 rotates on the horizontal plane, it can face different inner walls of the truck bucket. The coordination of forward, backward and left and right movements can make the cleaning nozzle 3 close to the inner wall of the truck bucket or move to change the cleaning position. At the same time, the cleaning nozzle 3 and the recovery box 4 can be flipped up and down. The upside down flipping of the cleaning nozzle 3 can change the flushing angle. After the recovery box 4 is flipped down, the waste water and solid particles recovered inside can be poured out.

[0044] There may be many cleaning methods. Taking the following cleaning process as an example, first, the inner wall of the front side of the truck bucket is cleaned, and the cleaning nozzle 3 faces the front side wall and is initially located above the front side wall (waste water may be pre-stored in the recovery box 4, or it may be considered that when different truck buckets are continuously cleaned, circulating waste water is used in the recovery box 4). The front end of the mounting frame 2 is swung downward and flipped, and the waste water (including solid particles) in the recovery box 4 is poured onto the front side wall to preliminarily rinse and moisten the attachments on the front side wall, and some solid particles are scattered and remain on the upward surface of the attachments. Then the suspension seat 105 descends, and the cleaning nozzle 3 moves downward and performs high-pressure rinsing. During the rinsing process, the attachments are gradually broken, and some waste water and particles are splashed and recovered by the recovery box 4. After the cleaning nozzle 3 rinses the lower part of the front side wall, the mount 105 rises, and the cleaning nozzle 3 rinses again to improve the cleanliness (you can choose whether to rinse again according to your needs, and the first flushing process can also be after the recycling box 4 pours waste water from the top, the cleaning nozzle 3 follows the mount 105 to first descend to the bottom of the bucket, and then moves upward from a small point to rinse. The flushing process can be set according to your needs). During the upward movement of the recycling box 4, part of the waste water is still recovered, and finally moves to the top of the front side wall to complete the cleaning of the front side wall. Then, the rotating frame 106 rotates to adjust the cleaning nozzle 3 to face the inner wall of the right side wall of the bucket, and the mount 105 moves horizontally to adjust the gap between the cleaning nozzle 3 and the right side wall. Then, the above cleaning process can be repeated. The front-to-back direction of the right side wall of the bucket is longer. After a single up and down lift to clean the corresponding area, the mount 105 moves back and forth to change the corresponding cleaning area for cleaning.

[0045] The truck bed is generally long in the front-to-back length direction and relatively narrow in the left-to-right width direction. In addition, the models of the mining trucks used in the same mine and the same fleet are basically the same, that is, the flushing length of the cleaning nozzle 3 can cover the width of the front side wall of the truck bed at one time. When cleaning the left and right side walls, it can be covered alternately by moving forward and backward, which can save flushing time and ensure a cleaner flushing.

[0046] Furthermore, a plurality of first water spray holes 301 are provided on one side of the cleaning nozzle 3 . The water outlet direction of the first water spray holes 301 is tilted and tilted downward toward the inner wall of the bucket. The first water spray holes 301 are located directly above the recovery port 401 .

[0047] When in use, the first water spray hole 301 of the cleaning nozzle 3 can be set roughly horizontally or tilted. When it is set horizontally, when washing the truck bucket, because the recovery box 4 is located below, the cleaning nozzle 3 cannot be lowered to the lowest point. Even if the high-pressure washing has a range, it cannot impact the bottom. At this time, the mounting frame 2 can be flipped at a certain angle so that the first water spray hole 301 faces downward to clean the bottom of the truck bucket. This flipping angle should ensure that the recovery box 4 does not flow out or less waste water flows out from the recovery port 401.

[0048] The first water spray hole 301 sprays water downward at an angle, and can spray water directly to the bottom of the truck bucket. When in use, the following process can be adopted: when flushing the middle and above areas of the inner wall of the truck bucket, the recovery box 4 is close to the inner wall, and the position where the first water spray hole 301 impacts the inner wall is higher than the recovery port 401, so that the recovery port 401 can receive waste water. When moving downward to flush the lower part of the inner wall, the cleaning nozzle 3 and the recovery box 4 follow the mounting frame 2 to move appropriately away from the inner wall, and the inclined first water spray hole 301 can directly flush the lower part of the inner wall. At this time, the impact position on the inner wall is lower than the recovery port 401.

[0049] Furthermore, the cleaning nozzle 3 is reciprocatingly slidably arranged on the mounting frame 2, and the sliding direction of the cleaning nozzle 3 is perpendicular to the water outlet direction of the first water spray hole 301, and also includes: a reciprocating drive mechanism 5, which is arranged on the mounting frame 2 and is used to drive the cleaning nozzle 3 to reciprocately slide.

[0050] When in use, the cleaning nozzle 3 reciprocates in the left and right directions, which can increase the direct flushing coverage area, improve flushing efficiency and flushing cleanliness. When the first water spray hole 301 flushes, there is a flushing area, but the central area is the main cleaning area. By reciprocating, the main cleaning area can be moved left and right, increasing the direct high-pressure flushing coverage area.

[0051] The reciprocating drive mechanism 5 can be of various types, such as realizing reciprocating motion through hydraulic equipment, or through gear rack structure drive, cam structure drive, screw structure drive, etc.

[0052] Furthermore, the cleaning nozzle 3 also has a plurality of second water spray holes 302 . The second water spray holes 302 are respectively arranged on both sides of the first water spray hole 301 . The water outlet direction of the second water spray holes 302 points to the inner wall of the truck bucket.

[0053] When in use, the first water spray hole 301 is arranged at the front side of the cleaning nozzle 3, and the second water spray holes 302 can be arranged at the left and right sides respectively. For example, when the first water spray hole 301 washes the front side wall, the second water spray hole 302 can wash the local area of ​​the left and right side walls. When the first water spray hole 301 turns to wash the left side wall, there is already a washed area in the front part of the left side wall. When the area is washed again or the area is partially washed, the splashing to the washed front side wall can be reduced.

[0054] Furthermore, it also includes: a stirring plate 6, which has a plurality of stirring plates 6, which are arranged in an array at an interval at the lower end of the cleaning nozzle 3, and the lower end of the stirring plate 6 extends to the lower part of the recovery box, and the lower part of the stirring plate 6 reciprocates in the lower part of the recovery box 4.

[0055] When in use, the stirring plate 6 can disturb and stir the wastewater and solid particles in the recovery box 4, which can reduce the precipitation of solid particles, so that more solid particles can be poured out when the wastewater is poured out of the recovery box 4. The reciprocating movement of the stirring plate 6 can also break up small pieces of structure immersed in the wastewater, generating more small particles, which are convenient for staying on the surface of the attachment.

[0056] Furthermore, a vertical side wall of the recovery box 4 close to the first water spray hole 301 is inclined, and the upper end of the inclined vertical side wall is closer to the inner wall of the bucket than the lower end.

[0057] When in use, the front side wall of the recovery box 4 is close to the first water spray hole 301, that is, it is an inclined vertical side wall, inclined outward, and the recovery port 401 is convenient for receiving waste water. When the recovery box 4 is turned over to dump the waste water, the residual waste water and solid particles in the recovery box 4 can be reduced.

[0058] Furthermore, it also includes: a slide 102, which is slidably set on the top frame 101; a translation seat 103, which is horizontally movable on the slide 102; a linear drive mechanism 104, which is set at the lower end of the translation seat 103, and the moving end of the linear drive mechanism 104 is set at the upper end of the hanging seat 105; wherein the slide 102 and the translation seat 103 are used to drive the hanging seat 105 to move horizontally, and the linear drive mechanism 104 is used to drive the hanging seat 105 to move up and down.

[0059] When in use, the horizontal movement and lifting of the hanging seat 105 can be realized by a variety of structures, for example, the sliding seat 102 can move forward and backward on the top frame 101, the translation seat 103 can move left and right on the sliding seat 102, and the linear drive mechanism 104 can be a hydraulic cylinder assembly to drive the lifting of the hanging seat 105. The movement of the sliding seat 102 and the translation seat 103 are all existing technologies and will not be described in detail herein.

[0060] Furthermore, it also includes: a rotating motor 107, which is arranged on the suspension seat 105 and is used to drive the rotating frame 106 to rotate; and a swing motor 108, which is arranged on the rotating frame 106 and is used to drive the mounting frame 2 to swing up and down.

[0061] When in use, the hanging seat 105 can be frame-shaped, with the lower part rotatably connected to the rotating frame 106 and hanging the rotating frame 106. The rotating motor 107 is vertically arranged in the hanging seat 105 to drive the rotating frame to rotate in the horizontal plane to change the cleaning nozzle 3 to face different inner walls.

[0062] The swing motor 108 is disposed on the rotating frame 106 , and the driving end drives the mounting frame 2 to rotate, that is, the mounting frame 2 can be swung up and down.

[0063] Equipment that needs to be waterproofed can be waterproofed according to existing technologies.

[0064] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
