Abstract
Description
Technical Field
[0001] This utility model relates to the field of health protection technology for the transfer and transportation of contaminated soil, and specifically to a health protection device for the transfer and transportation of contaminated soil. Background Technology
[0002] During the remediation and transfer of contaminated soil, especially in the co-processing of cement kilns, loaders are often used for transporting contaminated soil. However, the buckets of these loaders are often open without any protective devices, which makes it easy for soil to fall or spill during the transfer process, causing further environmental pollution and impacting human health. Utility Model Content
[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use health protection device for the transfer and transportation of contaminated soil, which can effectively solve the defects and shortcomings of the existing technology.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a transfer bucket and a connecting seat, wherein the connecting seat is fixed to one side of the outer wall of the transfer bucket; it also includes:
[0005] The first protective plate is set on one side of the transfer bucket. The second protective plate is vertically fixed to the lower side of the side wall of the first protective plate. The second protective plate is set inside the transfer bucket and has a built-in counterweight.
[0006] The rotating shaft is inserted through and fixed inside the top wall of the second protective plate. The front and rear ends of the rotating shaft are respectively screwed to the front and rear inner walls of the transfer bucket by bearings.
[0007] The movable scraper is movably inserted into the second protective plate. Push springs are equidistantly embedded and fixed inside the movable scraper. The other end of the push spring passes through the movable scraper and is fixed to the inner wall of the second protective plate.
[0008] The limiting mechanism is located inside the transfer hopper and cooperates with the second protective plate to abut against it.
[0009] The contact plate is movably inserted into the first protective plate. An anti-contact spring is fixed on the inner wall of the contact plate, and the other end of the anti-contact spring is fixedly connected to the inner wall of the first protective plate.
[0010] The sliding blocks are multiple in number and are respectively fixed on the two side walls of the contact plate. The sliding blocks are slidably disposed in the grooves on the inner wall of the first protective plate.
[0011] Through the above technical solution, the loader moves the transfer bucket towards the side of the contaminated soil, causing the soil to push the No. 2 protective plate towards one side of the transfer bucket, allowing the soil to enter the transfer bucket. The No. 2 protective plate drives the No. 1 protective plate to rotate. After pushing the soil into the transfer bucket, the No. 2 protective plate is limited by a limiting mechanism, while the No. 1 protective plate rotates to one side inside the transfer bucket. The elastic force of the contact spring causes the contact plate to move outward and contact the inner bottom wall of the transfer bucket, thereby shielding the contaminated soil and preventing it from falling out, achieving a protective effect. When the soil is moved to a suitable position, the limiting mechanism is released, releasing the No. 2 protective plate. At this time, the No. 2 protective plate moves the soil downward, causing the soil to fall to a suitable position. During this process, the movable scraper moves outward under the elastic force of the pushing spring and contacts the inner wall of the transfer bucket, thereby scraping off the soil and preventing it from adhering to the inner wall of the transfer bucket.
[0012] As a further improvement of this utility model, movable blocks are symmetrically fixed on both sides of the movable scraper, and the movable blocks are slidably arranged in the grooves on the two inner walls of the second protective plate.
[0013] The above technical solution can prevent the movable scraper from moving out of the second protective plate.
[0014] As a further improvement of this utility model, the contact plate is fixed with baffles on both the front and rear sides of the inner side wall of the first protective plate, and the baffles are movably inserted into the side wall of the first protective plate.
[0015] The above technical solution makes it easy to cover the gap between the No. 1 protective plate and the contact plate.
[0016] As a further improvement of this utility model, the limiting mechanism includes:
[0017] The limiting blocks are four in number, and they are symmetrically embedded in the front and rear inner walls of the transfer bucket in pairs. The lower side of one side wall of the limiting block is inclined towards one side of the inner wall of the transfer bucket. The limiting block is located inside the transfer bucket and slides in the groove on the inner wall of the transfer bucket by a slider.
[0018] The reset springs are of several kinds, and they are fixed symmetrically in pairs on the inner wall of the limiting block. The other end of the reset spring is fixed on the inner wall of the transfer bucket.
[0019] A fixing plate is fixed to the outer wall of one side of the transfer bucket. An electric push rod is fixed to the lower side of the fixing plate, and a pulling block is fixed to the piston rod of the electric push rod.
[0020] The connecting ropes consist of four ropes, each fixed to the inner wall of the limiting block. The other end of each rope passes through one side wall of the transfer bucket and the fixing plate, and is then fixed to the upper side wall of the pulling block.
[0021] With the above technical solution, when the No. 2 protective plate rotates upward, it abuts against the inclined surface of the limiting block, causing the limiting block to push the reset spring to move into the side wall of the transfer bucket, thus not affecting the movement of the No. 2 protective plate. When the No. 2 protective plate moves to the upper side of the limiting block, the limiting block resets under the elastic force of the reset spring and abuts against the lower side of the No. 2 protective plate, thus limiting the No. 2 protective plate. When unloading is required, the electric push rod is activated, which drives the pulling block to move downward. The pulling block drives the limiting block to move to one side inside the transfer bucket through the connecting rope, thereby releasing the limitation on the No. 2 protective plate and facilitating its movement.
[0022] As a further improvement of this utility model, the outer side wall of the movable scraper, the front and rear side walls of the first protective plate and the front and rear side walls of the second protective plate are all fixed with abutting pads, which are set to abut against the inner wall of the transfer bucket.
[0023] The above technical solution allows the inner wall of the transfer bucket to be wiped by the contact pad during the rotation of the movable scraper, the first protective plate, and the second protective plate, thereby preventing soil from adhering to the transfer bucket.
[0024] As a further improvement of this utility model, a rotary motor is fixed to one end of the rotating shaft. The rotary motor is connected to the power supply on the loader. The rotary motor is fixed on the outer wall of one side of the transfer bucket. The rotary motor is connected to a control switch. The control switch is embedded and fixed on the inner bottom wall of the transfer bucket.
[0025] With the above technical solution, after the transfer bucket is in the soil, the No. 2 protective plate will rotate into the transfer bucket. At this time, the push spring will move the movable scraper outward until it touches the control switch. The control switch will start the rotary motor. The rotary motor will drive the No. 2 protective plate and the No. 1 protective plate to rotate through the rotating shaft, thereby speeding up the material shoveling speed.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: The health protection device for transferring and transporting contaminated soil described in this utility model can shield and protect the soil during the transfer of contaminated soil, preventing the soil from polluting the environment again and causing harm to human health. It is also convenient for transfer. This utility model has the advantages of reasonable design and low manufacturing cost. Attached Figure Description

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0035] Example 1:
[0036] like Figures 1-5 As shown, this embodiment includes a transfer bucket 1 and a connecting seat 2, wherein the connecting seat 2 is welded and fixed to the left side of the outer wall of the transfer bucket 1; it also includes:
[0037] The first protective plate 3 is located on the right side of the transfer bucket 1. The second protective plate 4 is vertically welded and fixed to the lower side of the left side wall of the first protective plate 3. The second protective plate 4 is located inside the transfer bucket 1 and has a built-in counterweight.
[0038] A rotating shaft 5 is inserted through and welded to the top wall of the second protective plate 4. The front and rear ends of the rotating shaft 5 are respectively screwed to the front and rear inner walls of the transfer bucket 1 through bearings. A rotary motor 15 is fixed to the rear end of the rotating shaft 5. The rotary motor 15 is connected to the power supply on the loader. The rotary motor 15 is fixed to the outer wall of the rear side of the transfer bucket 1 by bolts. The rotary motor 15 is connected to the control switch 16. The control switch 16 is embedded in and fixed to the inner bottom wall of the transfer bucket 1 by bolts. After the transfer bucket 1 scoops up the soil, the second protective plate 4 is rotated into the transfer bucket 1. At this time, the push spring 7 moves the movable scraper 6 to the outside until it touches the control switch 16. The control switch 16 starts the rotary motor 15. The rotary motor 15 drives the second protective plate 4 and the first protective plate 3 to rotate through the rotating shaft 5, thereby speeding up the scooping speed.
[0039] The movable scraper 6 is movably inserted into the second protective plate 4. Push springs 7 are equidistantly embedded and welded inside the movable scraper 6. The right end of the push spring 7 passes through the movable scraper 6 and is welded to the inner wall of the second protective plate 4. Moving blocks 12 are symmetrically fixed on both sides of the movable scraper 6. The moving blocks 12 are slidably disposed in the grooves on the two inner walls of the second protective plate 4 to prevent the movable scraper 6 from moving out of the second protective plate 4.
[0040] The outer side wall of the movable scraper 6, the front and rear side walls of the first protective plate 3, and the front and rear side walls of the second protective plate 4 are all fixed with abutting pads 14. The abutting pads 14 are set to abut against the inner wall of the transfer bucket 1. During the rotation of the movable scraper 6, the first protective plate 3, and the second protective plate 4, the inner wall of the transfer bucket 1 can be wiped by the abutting pads 14, thereby preventing soil from adhering to the transfer bucket 1.
[0041] The limiting mechanism 8 is installed inside the transfer bucket 1, and the limiting mechanism 8 cooperates with the second protective plate 4 to abut against it.
[0042] A contact plate 9 is movably inserted into the first protective plate 3. A contact spring 10 is fixed on the inner wall of the contact plate 9, and the other end of the contact spring 10 is fixedly connected to the inner wall of the first protective plate 3. Baffles 13 are fixed on both the front and rear sides of the inner side wall of the first protective plate 3. The baffles 13 are movably inserted into the side wall of the first protective plate 3, which can facilitate the blocking of the gap between the first protective plate 3 and the contact plate 9.
[0043] Sliding blocks 11, there are several sliding blocks 11, and they are respectively welded and fixed on the two side walls of the contact plate 9. The sliding blocks 11 are slidably arranged in the groove on the inner wall of the first protective plate 3.
[0044] Example 2:
[0045] See Figure 1-4 As shown, based on Embodiment 1, the limiting mechanism 8 includes:
[0046] The limiting blocks 8-1 are four in number, and they are symmetrically embedded in the front and rear inner walls of the transfer bucket 1 in pairs. The lower side of one side wall of the limiting block 8-1 is inclined towards one side of the inner wall of the transfer bucket 1. The limiting block 8-1 located inside the transfer bucket 1 slides in the groove on the inner wall of the transfer bucket 1 through a slider.
[0047] The reset spring 8-2 consists of several springs, which are symmetrically welded and fixed to the inner wall of the limiting block 8-1 in pairs. The other end of the reset spring 8-2 is fixed to the inner wall of the transfer bucket 1.
[0048] The fixing plate 8-3 is fixed on the outer wall of the left side of the transfer bucket 1. The lower side of the fixing plate 8-3 is fixed with an electric push rod 8-4 by bolts. The piston rod of the electric push rod 8-4 is fixed with a pulling block 8-5 by bolts.
[0049] There are four connecting ropes 8-6, and they are fixed one-to-one on the inner wall of the limiting block 8-1. The other end of the connecting rope 8-6 passes through one side wall of the transfer bucket 1 and the fixing plate 8-3 in sequence, and is fixed on the upper side wall of the pulling block 8-5.
[0050] When using this invention, the loader moves the transfer bucket 1 towards the contaminated soil, causing the soil to push the second protective plate 4 towards one side of the transfer bucket 1, allowing the soil to enter the transfer bucket 1. The second protective plate 4 also drives the first protective plate 3 to rotate. After pushing the soil into the transfer bucket 1, the second protective plate 4 rotates upwards, abutting against the inclined surface of the limiting block 8-1. This causes the limiting block 8-1 to push the return spring 8-2 into the side wall of the transfer bucket 1, thus not affecting the movement of the second protective plate 4. When the second protective plate 4 moves to the upper side of the limiting block 8-1, the limiting block 8-1, under the elastic force of the return spring 8-2, returns to its original position and abuts against the lower side of the second protective plate 4, thus limiting the movement of the second protective plate 4. Meanwhile, the first protective plate 3 rotates. Inside the transfer bucket 1, the spring force of the contact spring 10 causes the contact plate 9 to move outward and contact the inner bottom wall of the transfer bucket 1, thereby shielding the contaminated soil and preventing it from falling out, thus achieving a protective effect. After the soil is moved to a suitable position, the electric push rod 8-4 is activated. The electric push rod 8-4 drives the pulling block 8-5 to move downward. The pulling block 8-5, through the connecting rope 8-6, drives the limiting block 8-1 to move to one side inside the transfer bucket 1, thereby releasing the limit on the second protective plate 4. At this time, the second protective plate 4 moves the soil downward, causing the soil to fall to a suitable position. During this process, the movable scraper 6 moves outward under the spring force of the pushing spring 7 and contacts the inner wall of the transfer bucket 1, thereby scraping off the soil and preventing it from adhering to the inner wall of the transfer bucket 1.
[0051] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:
[0052] 1. When the contaminated soil is shoveled up, the No. 2 protective plate 4 can be pushed so that the soil is located between the No. 1 protective plate 3 and the No. 2 protective plate 4, thereby shielding and protecting the soil from environmental pollution and facilitating its relocation.
[0053] 2. After the No. 2 protective plate 4 is rotated to the appropriate position, it can be limited by the limiting mechanism 8 to prevent soil from falling when it is shoveled.
[0054] 3. A movable scraper 6 is installed inside the second protective plate 4. The movable scraper 6 can be pushed by the spring 7, so as to scrape off the soil adhering to the inner wall of the transfer bucket 1 during the rotation of the second protective plate 4, thus preventing the soil from adhering to the transfer bucket 1.
[0055] 4. The rotary motor 15 located on the rear side of the rotating shaft 5 can be connected to the control switch 16 inside the transfer bucket 1. After the second protective plate 4 and the movable scraper 6 are rotated into the transfer bucket 1, the control switch 6 can be pressed to start the rotary motor 15 and speed up the transfer of soil.
[0056] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
