DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1: Figure 1-10As shown, a feeding mechanism of a soil remediation device described in an embodiment of the present invention includes a feeding shell 1 provided on the soil remediation device, and also includes: an inlet 2 and an outlet 3 opened on the feeding shell 1; a screening assembly 4 installed on the feeding shell 1, the screening assembly 4 includes: a No. 1 sieve plate 41 and a No. 2 sieve plate 42 installed on the feeding shell 1, the No. 2 sieve plate 42 is located below the No. 1 sieve plate 41, and the mesh number of the No. 1 sieve plate 41 is smaller than the mesh number of the No. 2 sieve plate 42.

[0024] Specifically, before repairing the soil, it is necessary to use the feeding mechanism of the soil remediation equipment to introduce the soil into the mixing mechanism of the soil remediation equipment; the existing device intercepts the stones through the screen on the feeding part to avoid damaging the machine when the soil is mixed and repaired. A layer of stones is laid on the farmland where watermelons are planted, which can not only prevent soil loss but also retain moisture in the ground. The above-mentioned device can only screen out the stones, but cannot screen the stones in the soil. After the repair is completed, the stones need to be screened again to screen out the larger stones, and the remaining stones are used to lay on the surface of the farmland; the feeding shell 1 is used to introduce the soil from the farmland and other places into the interior of the feeding mechanism of the soil remediation equipment, and the feeding shell 1 is slidably installed up and down on the feeding mechanism of the soil remediation equipment, and the outlet 3 of the feeding shell 1 is connected to the feeding mechanism of the soil remediation equipment. When working, the farmland The soil in the fields is dug out, and the soil is poured into the feed shell 1 from the feed port. The soil first falls above the No. 1 sieve plate 41, and the larger stones in the soil are blocked above the No. 1 sieve plate 41. The soil and smaller stones fall above the No. 2 sieve plate 42. The smaller stones are blocked above the No. 2 sieve plate 42 by the No. 2 sieve plate 42, and the soil enters the stirring mechanism of the soil remediation equipment from the outlet 3. The stirring mechanism of the soil remediation equipment continuously stirs the soil and sprays the soil remediation agent to achieve the soil remediation action. The remediated soil is again discharged to the farmland and the like; by setting the No. 1 sieve plate 41 and the No. 2 sieve plate 42, the larger stones are screened out from the soil, and the stones of the right size are screened above the No. 2 sieve plate 42. After the remediation is completed, the stones on the No. 2 sieve plate 42 can be re-laid on the surface of the farmland such as watermelon, which is convenient to use.

[0025] like Figure 3 - Figure 5As shown, the screening assembly 4 also includes: a No. 1 collecting box 43 and a conduit 44 fixedly mounted on one side of the feed shell 1; two slide plates 45 respectively mounted above the No. 1 sieve plate 41 and the No. 2 sieve plate 42, the slide plates 45 being slidably connected to the feed shell 1 and the partition plate 5; a No. 1 plate 46 mounted on the slide plates 45; a push plate 47 mounted on the No. 1 plate 46, the push plate 47 being used to push the stones on the No. 1 sieve plate 41 and the No. 2 sieve plate 42 into the No. 1 collecting box 43 and the conduit 44 respectively.

[0026] Specifically, a baffle is provided on one side of the No. 1 collecting box 43 and the conduit 44 close to the No. 1 sieve plate 41 and the No. 2 sieve plate 42, with the side where the No. 1 collecting box 43 is located as the rear side. After the soil remediation is completed, the baffle is controlled to open, and the slide plate 45 is controlled to slide backward, driving the push plate 47 to slide backward synchronously, and the stones on the No. 1 sieve plate 41 and the No. 2 sieve plate 42 are pushed into the No. 1 collecting box 43 and the conduit 44 respectively, the larger stones are stored in the collecting box, and the smaller stones are discharged from the conduit 44.

[0027] like Figure 2 - Figure 4 As shown, it also includes: a partition plate 5 installed on the feed shell 1, two groups of screening components 4 are arranged in the feed shell 1, and the two groups of screening components 4 are respectively located on both sides of the partition plate 5; two telescopic rods 6 slidably installed on the feed shell 1; and a cover plate 7 rotatably installed on the two telescopic rods 6.

[0028] Specifically, the side where the conduit 44 extends out of the shell is the right side. In the initial state, the cover plate 7 is located above the screening assembly 4 on the right. At this time, the telescopic rod 6 on the right of the two telescopic rods 6 is in an extended state, so that the cover plate 7 is tilted to the left, so that the soil falls onto the screening assembly 4 on the left. The screening assembly 4 on the left screens the stones in the soil. When the No. 1 sieve plate 41 and the No. 2 sieve plate 42 of the screening assembly 4 on the left accumulate more stones, the telescopic rod 6 is controlled to slide to the left until the telescopic rod 6 on the left is in contact with the wall surface on the left side of the feed shell 1. The telescopic rod 6 moves and retracts at the same time, so that the cover plate 7 is tilted to the right, and the soil is introduced into the screening assembly 4 on the right. At this time, the screening assembly 4 on the right screens the stones in the soil, and the slide plate 45 and the push plate 47 of the left screening assembly 4 are controlled to move, and the stones on the No. 1 sieve plate 41 and the No. 2 sieve plate 42 are pushed into the No. 1 collection box 43 and the conduit 44 respectively. At this time, the stones are discharged from the conduit 44 to the farmland, which is convenient to use.

[0029] like Figure 1 and Figure 4 As shown, it also includes a No. 2 collecting box 8 installed on the cover plate 7 , and a pump body 9 is provided on the outer side of the No. 1 collecting box 43 , and the pump body 9 is connected to the No. 2 collecting box 8 .

[0030] Specifically, the pump body 9 adopts an air suction pump, and a baffle is provided on the side of the No. 2 collecting box 8 close to the No. 1 sieve plate 41. Since there may be plastic film fragments, empty plastic bottles and other garbage in the farmland, taking the operation of the left screening component 4 as an example, the baffle of the No. 2 collecting box 8 on the right screening component 4 is controlled to open, and the pump body 9 is controlled to start, and the space where the right screening component 4 is located is evacuated, so that the plastic film fragments and empty plastic bottles blocked on the No. 1 sieve plate 41 can be pumped into the No. 1 collection box, which is easy to use.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the screening assembly 4 also includes: a slide bar 10 slidably installed on both sides of the No. 1 sieve plate 41 and the No. 2 sieve plate 42, and the No. 1 sieve plate 41 and the No. 2 sieve plate 42 are connected to the inner wall of the feed shell 1 through the slide bar 10; a No. 1 rotating rod 49 and a No. 2 rotating rod 410 rotatably installed on the inner wall of the feed shell 1, and the No. 1 rotating rod 49 and the No. 2 rotating rod 410 adopt a telescopic structure, the No. 1 rotating rod 49 is detachably connected to the No. 1 sieve plate 41, and two No. 1 sieve plates 41 are provided at both ends of the No. 1 rotating rod 49, the No. 2 rotating rod 410 is detachably connected to the No. 2 sieve plate 42, and two No. 2 sieve plates 42 are provided at both ends of the No. 2 rotating rod 410; windows 411 are opened on both sides of the feed shell 1.

[0032] As shown in the figure, the screening assembly 4 also includes: a connecting plate 412 installed on both sides of the push plate 47, and the connecting plate 412 is slidably connected to the No. 1 plate 46; a No. 1 spring 413 installed between the connecting plate 412 and the No. 1 plate 46; and a No. 1 switch 414 installed on the No. 1 plate 46, and the No. 1 switch 414 is located within the moving range of the connecting plate 412.

[0033] Specifically, since the No. 1 sieve plate 41 and the No. 2 sieve plate 42 are subjected to soil and stones falling from above for a long time, the No. 1 sieve plate 41 and the No. 2 sieve plate 42 may be damaged or deformed by stones. The position of the No. 1 sieve plate 41 and the No. 2 sieve plate 42 which are perpendicular to the window 411 is used as the working position, and the No. 1 switch 414 is a push-type. After the No. 1 switch 414 is triggered, it can control the No. 1 rotating rod 49 or the No. 2 rotating rod 410 on the corresponding horizontal plane to rotate. In the initial state, the No. 1 spring 413 is in a compressed state. During the sliding process of the slide plate 45 backward, the No. 1 plate 46 and the push plate 47 slide backward synchronously. If there is a deformation problem, the push plate 47 moves downward under the action of the elastic force of the No. 1 spring 413. After the push plate 47 moves downward, it can press the No. 1 switch 414, thereby triggering a No. 1 switch 414. After the No. 1 switch 414 is triggered, the No. 1 switch 414 controls the No. 1 rotating rod 49 or the No. 2 rotating rod 410 on the corresponding horizontal plane to rotate. Taking the deformation of the No. 1 sieve plate 41 as an example, after the No. 1 switch 414 is triggered, the control slide bar 10 slides toward the inside of the No. 1 sieve plate 41, so that the No. 1 sieve plate 41 is separated from the shell, and then the No. 1 rotating rod 49 rotates counterclockwise, and the No. 1 rotating rod 49 is retracted to ensure that the two No. 1 sieve plates 41 on the No. 1 rotating rod 49 can rotate synchronously. After the No. 1 rotating rod 49 rotates 90 degrees counterclockwise, the No. 1 sieve plate 41 that is in contact with the partition plate 5 is transferred to the work station, and the No. 1 sieve plate 41 at the work station is transferred to one side of the window 411. The staff can remove the deformed No. 1 sieve plate 41 from the rotating rod through the window 411 for maintenance. It is easy to use and does not require shutdown for maintenance.

[0034] like Fig. 9 As shown, the connecting plate 412 is rotatably connected to the push plate 47 , and a first torsion spring 415 is installed between the connecting plate 412 and the push plate 47 .

[0035] Specifically, due to the irregular shape of the stones, there is a problem that the stones are stuck in the sieve holes of the No. 1 sieve plate 41 or the No. 2 sieve plate 42. If the push plate 47 contacts the stones stuck in the sieve holes and pushes the stones to the front and rear sides, there is a problem that the sieve holes of the sieve are damaged. By setting a rotating push plate 47, when the push plate 47 encounters a stone blocking the sieve holes, the push plate 47 rotates upward. At this time, the No. 1 torsion spring 415 is twisted until the push plate 47 passes the stone. The push plate 47 returns to its original state under the action of the elastic force of the No. 1 torsion spring 415, thereby improving the above-mentioned problem.

[0036] like Figure 7 and Fig. 9 As shown, the No. 1 plate 46 is provided with a plurality of groups of the push plates 47 , the connecting plates 412 , the No. 1 springs 413 and the No. 1 switches 414 .

[0037] Specifically, if there are larger stones in the soil, the No. 1 sieve plate 41 and the No. 2 sieve plate 42 may be partially damaged or deformed by the stones. For a whole long push plate 47, it is impossible to detect the problem of partial damage or deformation by stones. By setting multiple groups of smaller push plates 47, connecting plates 412, No. 1 springs 413 and No. 1 switches 414, the detection is more accurate.

[0038] like Fig. 9 and Fig.10 As shown, the screening assembly 4 also includes: a number of rods 416 and rods 417 slidably mounted on the slide 45; a long plate 418 slidably mounted on the slide 45, the long plate 418 being located within the moving range of the rod 417; a connecting rod 419 driving the rod 416 to slide up and down, the two ends of the connecting rod 419 being rotatably connected to the push plate 47 and the rod 416; a triangular block 420 rotatably mounted on the rod 416; a triangular block 421 slidably mounted on the rod 417; a torsion spring 422 mounted between the triangular block 420 and the rod 416 ... a No. 2 spring 423 installed between the slide plate 45 and the long plate 418; a No. 3 spring 424 installed between the slide plate 45 and the long plate 418; a ratchet 425 rotatably installed on the slide plate 45; a cam 426 fixedly installed on the ratchet 425; a No. 2 switch 427 fixedly installed on the slide plate 45, the No. 2 switch 427 being located within the moving range of the cam 426; a pawl 428 rotatably installed on the long plate 418, the pawl 428 being used to drive the ratchet 425 to rotate; a No. 3 torsion spring 48 installed between the ratchet 425 and the slide plate 45; a check block 429 slidably installed on the slide plate 45, the check block 429 being used to limit the one-way rotation of the ratchet 425, the check block 429 being of a telescopic structure.

[0039] Specifically, the No. 1 triangular block 420 can only rotate downward, and the No. 4 torsion spring 422 is used to restore the No. 1 triangular block 420 to its original state after rotating. After the push plate 47 contacts the stone blocking the No. 1 sieve plate 41 or the No. 2 sieve plate 42, the push plate 47 rotates. At this time, the No. 1 torsion spring 415 is in a torsion state, and the rotation of the push plate 47 drives the connecting rod 419 to rotate upward synchronously. The rotation of the connecting rod 419 drives the No. 1 rod 416 to move upward, and the No. 1 rod 416 moves upward to drive the No. 1 triangular block 420 to move upward. Since the No. 1 triangular block 420 contacts the No. 2 triangular block 421, the No. 1 triangular block 420 needs to rotate through the No. 2 triangular block 421. When the push plate 47 passes the blocking After the stone on the No. 1 sieve plate 41 or the No. 2 sieve plate 42 is removed, the push plate 47 returns to its original state under the action of the elastic force of the No. 1 torsion spring 415, and the push plate 47 returns to its original state to drive the No. 1 to move downward. During the downward movement of the No. 1 rod 416, the No. 1 triangular block 420 contacts the No. 2 triangular block 421 on the No. 2 rod 417, and pushes the No. 2 rod 417 downward through the No. 2 triangular block 421. After the No. 2 rod 417 moves downward, it can push the long plate 418 to move downward. At this time, the No. 3 spring 424 is compressed, and the long plate 418 moves downward and pushes the ratchet 425 to rotate through the pawl 428. At this time, the No. 3 torsion spring 48 is twisted, and the rotation of the ratchet 425 drives the cam 426 to rotate. The first triangular block 421 moves downward and is pushed into the second rod 417 by the first triangular block 420. At this time, the second spring 423 is compressed. When the first triangular block 420 is no longer in contact with the second triangular block 421, the first triangular block 420 passes through the second triangular block 421. The second triangular block 421 moves out of the second rod 417 under the elastic force of the second spring 423. At this time, the long rod moves up to the initial state under the elastic force of the third spring 424. If there are multiple blocked stones on the same row of sieve holes, due to the different sizes of the stones, the time for the push plate 47 to pass through the stones is inconsistent. The time for each group of second rods 417 to push the long plate 418 downward is different. Each time the long rod is moved downward, the ratchet 425 and the cam 426 can be rotated a little. When the slide plate 45 slides forward to the initial position, the check block 429 can be controlled to slide downward until it is not in contact with the ratchet 425. At this time, the ratchet 425 rotates to the initial state under the elastic force of the No. 3 torsion spring 48. If there are multiple blockages on the No. 1 sieve plate 41 or the No. 2 sieve plate 42, the cam 426 can rotate to contact the No. 2 switch 427 during the backward sliding process. After the No. 2 switch 427 is triggered, the No. 1 rotating rod 49 or the No. 2 rotating rod 410 can be controlled to rotate to replace the No. 1 sieve plate 41 or the No. 2 sieve plate 42. Otherwise, the No. 2 switch 427 is not triggered.

[0040] Embodiment 2: Figure 8 As shown, compared with Example 1, another implementation of the present invention is that the No. 1 plate 46 and the slide plate 45 are connected in an up and down sliding manner.

[0041] Specifically, after the push plate 47 has pushed the stones, the slide plate 45 is located at the rear side of the No. 1 sieve plate 41 and the No. 2 sieve plate 42, and the No. 1 plate 46 is controlled to move upward relative to the slide plate 45, driving the push plate 47 to move upward synchronously, and then the slide plate 45 is controlled to slide forward, driving the No. 1 plate 46 and the push plate 47 to move forward, until the slide plate 45 is located at the front of the No. 1 sieve plate 41 and the No. 2 sieve plate 42, and the No. 1 plate 46 is controlled to slide downward relative to the slide plate 45 to the initial state. During the return journey, the push plate 47 is driven upward by the No. 1 plate 46 to avoid contact with the stones blocking the sieve holes on the No. 1 sieve plate 41 and the No. 2 sieve plate 42, thereby improving the problem of the push plate 47 generating thrust on the stones and causing deformation of the sieve holes.

[0042] Working principle: In the initial state, the cover plate 7 is located above the screening component 4 on the right. At this time, the telescopic rod 6 on the right of the two telescopic rods 6 is in an extended state, so that the cover plate 7 is tilted to the left to facilitate the soil to fall onto the screening component 4 on the left. When working, the soil in the farmland and other fields is dug out, and the soil is poured into the feed shell 1 from the feed port. The soil first falls above the No. 1 sieve plate 41 of the left screening component 4, and the larger stones in the soil are blocked above the No. 1 sieve plate 41. The soil and smaller stones fall above the No. 2 sieve plate 42. The smaller stones are blocked above the No. 2 sieve plate 42 by the obstruction of the No. 2 sieve plate 42, and the soil enters the mixing mechanism of the soil remediation equipment from the outlet 3. The mixing mechanism of the soil remediation equipment continuously mixes the soil. Stir and spray the soil repair agent to repair the soil. The repaired soil is discharged to farmland and other places again. When the No. 1 sieve plate 41 and the No. 2 sieve plate 42 of the left screening component 4 accumulate more stones, control the telescopic rod 6 to slide to the left until the telescopic rod 6 on the left is in contact with the wall on the left side of the feed shell 1. The telescopic rod 6 moves and retracts at the same time, so that the cover plate 7 tilts to the right, and the soil is introduced into the screening component 4 on the right. At this time, the screening component 4 on the right screens the stones in the soil, and control the slide plate 45 and the push plate 47 of the left screening component 4 to move, and push the stones on the No. 1 sieve plate 41 and the No. 2 sieve plate 42 into the No. 1 collection box 43 and the conduit 44 respectively. At this time, the stones are discharged from the conduit 44 to the farmland, which is convenient to use.
