Description

Technical Field

[0001] The utility model relates to the technical field of material cleaning equipment, in particular to a rotary material cleaning machine. Background Art

[0002] Stabilized soil mixer is a set of special equipment for continuous mixing of road base materials. It is suitable for the construction of base materials for ordinary roads, high-grade roads, expressways, urban roads, stadiums, airports, etc. During the operation of the existing stabilized soil mixing equipment, due to the high humidity of the water-stabilized material, the feeding belt conveyor sticks (carries material), causing material return when the feeding belt conveyor rotates. The accumulation of returned material will affect the normal operation of the feeding belt conveyor. In severe cases, it will cause damage to the feeding belt conveyor, resulting in the inability of the stabilized soil mixing equipment to produce normally.

[0003] In order to solve the problem of return material accumulation, in the prior art, a water pump is usually used to blow the return material to the ground in time when the belt conveyor is working; since the return material will solidify if it is not processed for a long time, it needs to be processed manually using electric tools such as electric drills, electric hammers, and electric chisels, which greatly increases the labor intensity of the staff and will cause the following problems:

[0004] 1. Once the feeding belt conveyor is started, the water pump needs to be turned on in time, resulting in a waste of water resources;

[0005] 2. The returned material cannot be used normally after washing, and becomes waste;

[0006] 3. The waste generated by water flushing can only be disposed of, causing environmental pollution;

[0007] 4. Cleaning the returned materials requires the cooperation of multiple people and equipment. The investment of manpower and mechanical equipment will greatly increase production costs, thus affecting economic benefits;

[0008] 5. When cleaning the returned material, the equipment needs to be shut down, which seriously reduces production efficiency. Summary of the invention

[0038] In order to further improve the scraping effect and realize that the lower end of the scraper 9 always presses the rubber pad 10, in the utility model, a plurality of scrapers 9 close to each other are arranged on each support plate 8 along the front-to-back direction, and each scraper 9 is vertically slidably connected to the support plate 8, and a pressing drive mechanism for driving the lower end of the scraper 9 to always press the rubber pad 10 is also arranged between the scraper 9 and the support plate 8;

[0039] In this embodiment, the pressing drive mechanism includes a reset spring 17 and a pressure block 18.

[0042] In order to achieve a better use effect, a first arc plate 23 and a second arc plate 24 are respectively provided at the left and right ends between the first L-shaped plate 11 and the second L-shaped plate 12. When the scraper 9 rotates clockwise from bottom to top, the first arc plate 23 can be gradually compressed by the return spring 17 driven by the scraper 9, so that the scraper 9 moves smoothly to the top of the rubber pad 10, and is driven by the return spring 17 to move downward to press the rubber pad 10.

[0044] When the utility model is in use, in the initial state, the housing 1 is located below the feeding belt conveyor. When the feeding belt conveyor is running, the forward-reverse switch is started, and the forward-reverse switch controls the motor 13 to turn on through the power supply control circuit;

[0045] Working principle of the power supply control circuit: the start button SB2 is a normally open contact, and the stop button SB1 is a normally closed contact. When the start button SB2 is pressed, the circuit where the coil of the contactor KM is located is connected, and the coil is energized to make the main contact K1 and the normally open auxiliary contact K2 of the contactor KM attract, and the circuit where the main contact K1 and the normally open auxiliary contact K2 of the contactor KM are located is connected, the entire circuit is energized, and the motor 13 starts; when the start button SB2 is released, the entire circuit is still energized, and the entire circuit is energized through the normally closed contact K3 of the thermal relay FR, the stop button SB1 and the normally open auxiliary contact K2 of the contactor KM to enable the coil of the contactor KM to work, realizing the self-locking function; when the stop button SB1 is pressed, the circuit where the coil of the contactor KM is located is disconnected, the coil is de-energized, so that the main contact K1 and the normally open auxiliary contact K2 of the contactor KM are not attracted, the entire circuit is disconnected, the motor 13 stops working, and the start-stop function is realized.

[0046] The motor 13 drives the active shaft 2 to rotate clockwise through the reducer 14, the active shaft 2 drives the first sprocket 4 and the second sprocket 5 to rotate clockwise, the two first sprockets 4 drive the first chain 6 to rotate clockwise, the two second sprockets 5 drive the second chain 7 to rotate clockwise, the first chain 6 and the second chain drive the plurality of support plates 8 to rotate clockwise, the support plates 8 drive the plurality of scrapers 9 to rotate clockwise along the tracks of the first chain 6 and the second chain 7;

[0047] When the feeding belt conveyor rotates, the returned material falls on the rubber pad 10 below the feeding belt conveyor and will not accumulate on the ground to affect the operation of the belt conveyor. When the scraper 9 rotates to above the first curved plate 23, the scraper 9 contacts the left end of the rubber pad 10, and the first curved plate 23 gradually presses the scraper 9 upward, and the scraper 9 drives the pressure block 18 to slide upward along the slide groove 19, and the pressure block 18 gradually presses the return spring 17 upward. At the same time, the return spring 17 drives the scraper 9 to move vertically downward through the pressure block 18, so that the pressure between the scraper 9 and the rubber pad 10 gradually increases. There are multiple scrapers 9 on each support plate 8, so that the scrapers 9 at different positions can press the rubber pad 10 downward;

[0048] Multiple scrapers 9 drive the returned material on the rubber pad 10 to move to the right. When the scraper 9 moves to above the second curved plate 24, the pressure between the second curved plate 24 and the scraper 9 gradually decreases, and the reset spring 17 drives the pressure block 18 to move vertically downward in the slide groove 19. The pressure block 18 drives the scraper 9 to move vertically downward, and the reset spring 17 gradually restores its original length. The pressure between the scraper 9 and the rubber pad 10 gradually decreases, and the returned material falls into the collection container, which is convenient for the staff to uniformly reuse the returned material, which is conducive to reducing waste and reducing production costs.
