Description

Technical Field

[0001] This invention belongs to the field of saline-alkali land soil improvement technology, specifically a saline-alkali land soil improvement device. Background Technology

[0002] Saline-alkali land improvement refers to the process of reducing excessive soluble salts and exchangeable sodium ions in the soil through a series of physical, chemical, hydraulic, and biological measures, thereby improving soil structure and fertility to make it suitable for crop or vegetation growth and restoring or enhancing land productivity. Simply put, it transforms "bad" land—highly saline, alkaline, structurally unfavorable, and unsuitable for plant growth—into "good" land suitable for cultivation. Successful improvement not only increases arable land area, improves agricultural productivity and food security, but also improves the ecological environment, making it of great significance. Currently, both domestically and internationally, significant resources are being invested in the comprehensive management and development of saline-alkali land.

[0003] For the improvement of saline-alkali soil, the general method is to drive deep loosening teeth into the compacted layer of the soil and inject amendments such as organic fertilizers, microbial agents, and acidic substances into the interior. In practice, deep loosening teeth break through the compacted layer by moving in a straight line under the traction of external power. This linear movement of deep loosening teeth has a weak effect on breaking through the compacted layer, which may cause the amendment to not penetrate deeper and be discharged into the designated location, resulting in poor amendment effect.

[0004] Therefore, we propose a soil improvement device for saline-alkali land to solve the above problems. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies and proposes a soil improvement device for saline-alkali land; this invention is achieved through the following technical solution: A soil improvement device for saline-alkali land includes a deep tillage main frame plate, a deep tillage frame plate fixedly connected to one end of the deep tillage main frame plate, and deep tillage toothed plates arranged laterally at intervals on one side of the deep tillage frame plate. The deep tillage main frame plate is connected to a traction device. A feeding pipe is longitudinally installed on the inner side of the deep tillage toothed plates. A transparent feeding bin corresponding to the deep tillage toothed plates is installed on the top of the deep tillage frame plate via a bracket. The transparent feeding bin contains an amendment. A discharge chamber is connected to the bottom of the transparent feeding bin and is connected to the feeding pipe via a flexible hose. Deep tillage toothed mounting columns are installed on the front side of the deep tillage frame plate. The inside of the deep tillage toothed mounting columns has mounting column grooves corresponding to the number of deep tillage toothed plates. A sliding mounting plate that slides laterally along the mounting column groove is connected to the top of the deep tillage toothed plates. An intercepting cross plate is slidably connected to the discharge chamber, and the discharge chamber is opened or closed by the intercepting cross plate. A servo motor is installed on the deep tillage frame plate, and the servo motor drives the sliding mounting plate and the intercepting cross plate.

[0006] Furthermore, the bottom of the deep loosening toothed plate is a pointed cone in the vertical direction; the rear part of the deep loosening toothed plate has a tapered structure that narrows from wide to narrow along the traction direction. When the deep loosening toothed plate is subjected to traction, the tapered structure at the rear of the deep loosening toothed plate breaks the compacted layer to both sides, forming a soil trench structure; both sides of the deep loosening toothed plate are also tapered structures. When the deep loosening toothed plate moves laterally, the tapered structures on both sides break the soil laterally.

[0007] Furthermore, both ends of the deep-soiled frame plate are equipped with mounting column shafts, the rear ends of which are fixed to the surface of the deep-soiled frame plate. The deep-soiled tooth mounting columns are rotatably connected to the mounting column shafts. At the bottom of both ends of the deep-soiled frame plate, shaft positioning protrusions are fixedly connected, and at both ends of the deep-soiled tooth mounting columns, mounting column extension plates are fixedly connected. Both the shaft positioning protrusions and the mounting column extension plates are provided with positioning holes. When the mounting column extension plates and the deep-soiled tooth mounting columns are both attached to the surface of the deep-soiled frame plate, the positioning holes on the surface of the shaft positioning protrusions are aligned with the positioning holes on the surface of the mounting column extension plates. The deep-soiled tooth mounting columns and the deep-soiled frame plate are fixed by inserting bolts through the aligned positioning holes.

[0008] Furthermore, a mounting plate slot is formed on the surface of the sliding mounting plate away from the inner groove of the mounting column. The mounting plate slot is a rectangular slot, and the insertion direction of the mounting plate slot is located on the side of the sliding mounting plate away from the inner groove of the mounting column. A toothed plate top post is fixedly set on the top of the deep loosening toothed plate. The diameter of the toothed plate top post is smaller than the groove width of the mounting plate slot, and multiple sets of top post horizontal inserts are fixedly set on the surface of the toothed plate top post at equal intervals along the longitudinal direction. The width of the top post horizontal insert is also smaller than the groove width of the mounting plate slot, and the groove shape of the top post horizontal insert is adapted to the mounting plate slot. Positioning holes are formed on the surfaces of the top post horizontal inserts and the sliding mounting plate. After the top post horizontal insert is inserted into the mounting plate slot, the positioning holes of the top post horizontal insert and the positioning holes of the sliding mounting plate are aligned. At this time, the sliding mounting plate and the top post horizontal insert are locked and reinforced by bolts.

[0009] Furthermore, the servo motor output is connected to a functional rotating main disk. The external structure of the functional rotating main disk includes a central disc-shaped structure and symmetrically arranged arc-shaped protrusions on both sides of the disc-shaped structure. A concave rotating disk outer groove is provided in the middle of the side wall of the functional rotating main disk, and the groove shape of the rotating disk outer groove is consistent with the external shape of the functional rotating main disk. The top end of the sliding block is slidably connected to the rotating disk outer groove, and the bottom end of the sliding block is located outside the functional rotating main disk and is fixedly connected to an adjusting upright plate. The adjusting upright plate is connected to multiple sliding mounting plates through a linkage main rod.

[0010] Furthermore, a plug-in pressure plate is fixedly connected to the bottom of the adjusting upright plate, wherein the surface of the plug-in pressure plate is provided with an insertable through hole; a positioning horizontal insert is fixedly connected to one end of the linkage main rod; the positioning horizontal insert is rotatably connected in the through hole, and a synchronous connecting plate is rotatably connected to the end of the linkage main rod away from the positioning horizontal insert, wherein the bottom of the synchronous connecting plate is fixedly connected to the top of multiple sliding mounting plates.

[0011] Furthermore, a chute is horizontally opened at the bottom of the discharge chamber, and an intercepting horizontal plate is slidably connected in the chute. The two ends of the intercepting horizontal plate are fixedly provided with side protrusions, and the height of the side protrusions gradually increases from the side closer to the discharge chamber to the side farther away from the discharge chamber. Side grooves that are adapted to the side protrusions of the horizontal plate are provided on both sides of the chute. A material pushing plate is installed above the intercepting horizontal plate and on the surface of the discharge chamber. The material pushing plate has a fan-shaped cross-section, and one side of the material pushing plate is hinged to a hole opened on the surface of the discharge chamber. When the intercepting horizontal plate slides out of the discharge chamber, the material pushing plate rotates towards the inside of the discharge chamber, and the material pushing plate squeezes the modifier in the discharge chamber downward to assist in the discharge.

[0012] Furthermore, a longitudinally mounted trigger plate is provided on one side of the functional rotating main disk. A supporting and fixing side plate is provided on the bottom side of the trigger plate. The side of the supporting and fixing side plate is fixedly connected to the surface of the deep loose frame plate. A side plate transverse groove is provided on the surface of the supporting and fixing side plate. A transverse groove sliding block extending into the groove of the side plate is fixedly connected to the bottom of the trigger plate. A locking screw hole distributed in a ring array is provided at the front end of the functional rotating main disk. A limiting mounting plate is attached to the surface of the functional rotating main disk. One end of the limiting mounting plate is connected to the locking screw hole, and the other end of the limiting mounting plate is provided with a disc structure. The disc structure of the limiting mounting plate intermittently collides and contacts one side of the trigger plate. A trigger horizontal push rod is connected to the other side of the trigger plate. The trigger horizontal push rod is connected to the intercepting horizontal plate. The intercepting horizontal plate moves laterally by the lateral movement of the trigger plate.

[0013] Furthermore, a top-protruding adapter slider is slidably connected to the top of the side protrusion of the horizontal plate, and a toggle block is fixedly provided on the top of the top-protruding adapter slider.

A horizontal plate inner moving block is slidably connected in the sliding groove of the limiting horizontal plate. A sliding adapter block is provided at one end of the horizontal plate inner moving block. One end of the sliding adapter block is a cylindrical structure, and the other end of the sliding adapter block is a U-shaped groove structure. The cylindrical structure and the U-shaped groove structure are connected by an L-shaped connecting rod. One end of the cylindrical structure is fixedly connected to the horizontal plate inner moving block, and the side wall of the cylindrical structure is slidably connected to the convex-shaped groove on the corresponding toggle block. A rotating toggle plate is rotatably connected to the material pushing plate through a rotating shaft. The end of the rotating toggle plate away from the material pushing plate is inserted into the U-shaped groove structure of the sliding adapter block.

[0014] Furthermore, a longitudinal groove is provided on the surface of the discharge chamber, and a slider embedded in the longitudinal groove is provided on the surface of the actuating top block. The slider and the longitudinal groove provide longitudinal movement limit for the actuating top block. A vertical plate limiting sleeve is sleeved in the middle area of ​​the adjusting vertical plate, and one end of the vertical plate limiting sleeve is fixedly connected to the deep loosening frame plate. The vertical plate limiting sleeve provides longitudinal sliding limit for the adjusting vertical plate.

[0015] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention involves installing multiple sets of spaced deep loosening tooth plates in front of a deep loosening tooth installation column, and creating an inner groove within the column that allows the sliding installation plate to move left and right. The sliding installation plate is connected to the deep loosening tooth plate via a top column transverse insert plate. By moving the sliding installation plate left and right within the groove of the column, the deep loosening tooth plate can more fully break the soil on both sides of the forward direction after breaking the compacted layer. This allows the feed pipe on the inner side of the deep loosening tooth plate to flow more accurately into the soil groove of the plate, reducing the impact of the broken soil on the application of the soil conditioner and thus helping to improve the soil improvement quality of the soil conditioner.

[0016] 2. This invention uses a set of servo motors to drive the adjustment plate section to move longitudinally back and forth under the rotation of the functional rotating main disk. This allows for the synchronous movement of multiple deep loosening toothed plates via the linkage main rod and synchronous connecting plate. Simultaneously, the rotation of the functional rotating main disk enables the limiting mounting plate section to perform circular motion, periodically triggering the movement of the vertical plate section. The triggering plate section is connected to an intercepting horizontal plate via a trigger push rod. The reciprocating movement of the intercepting horizontal plate periodically intercepts and opens the discharge area inside the discharge chamber, enabling automated interval dispensing of the modifier and making the dispensing of the modifier more convenient.

[0017] 3. This invention, by intercepting the movement of the horizontal plate, and through the connection of the inner moving block, the top moving block, the sliding adapter block, and the rotating moving vertical plate, enables the material pushing plate to move synchronously when the horizontal plate moves. The material pushing plate, with a fan-shaped cross-section, can exert a downward pressure effect on the modifier stored inside the discharge chamber by rotating inward, which reduces the occurrence of modifier blockage to a certain extent and improves the discharge smoothness of the modifier.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0021] See Figures 1 to 9 This embodiment proposes a soil improvement device for saline-alkali land, including a deep loosening main frame plate 1, a deep loosening frame plate 2 fixedly connected to one end of the deep loosening main frame plate 1, and deep loosening tooth plates 22 arranged laterally on one side of the deep loosening frame plate 2. The deep loosening main frame plate 1 is connected to a traction device, which is used to provide power for the movement of the deep loosening main frame plate 1.

[0022] The bottom of the deep loosening toothed plate 22 is a pointed cone in the vertical direction. In practical applications, the pointed cone bottom makes it easy to break the soil from the vertical direction. The rear part of the deep loosening toothed plate 22 is a cone-shaped structure that narrows from wide to narrow along the traction direction. When the deep loosening toothed plate 22 is tractioned, the cone-shaped structure at the rear breaks the compacted layer to both sides, forming a soil trench structure, which facilitates the subsequent application of soil conditioner in the soil trench. The two sides of the deep loosening toothed plate 22 are also sharp cone-shaped structures. When the deep loosening toothed plate 22 moves laterally, the cone-shaped structures on both sides break the soil laterally.

[0023] A feeding pipe section 23 is installed longitudinally on the inner side of the deep loosening tooth plate 22. The bottom of the feeding pipe section 23 is located above the conical bottom of the deep loosening tooth plate 22. When the soil is broken at the conical bottom of the deep loosening tooth plate 22, the situation of soil clogging the bottom opening of the feeding pipe section 23 can be greatly reduced, thus reducing the maintenance rate. The top of the feeding pipe section 23 has an upward-protruding connection port; the top of the deep loosening frame plate 2 is equipped with a transparent feeding bin 24 corresponding to the deep loosening toothed plate 22 via a bracket. The transparent feeding bin 24 contains the modifier. The bottom of the transparent feeding bin 24 is connected to the discharge chamber 25, which also has a connection port at its bottom. The connection port at the bottom of the discharge chamber 25 is connected to the corresponding connection port at the top of the feeding pipe section 23 via a flexible hose. It is worth noting that a spring sleeve is provided on the outer sleeve of the flexible hose, so that the flexible hose can be bent in actual operation without bending. The modifier is fed downward through the discharge chamber 25 at the bottom of the transparent feeding bin 24 and enters the feeding pipe section 23 through the flexible hose. The material transfer between the discharge chamber 25 and the feeding pipe section 23 will not be blocked. The flexible hose and the spring sleeve are not shown in the attached drawings. The spring sleeve is made of 304 stainless steel spring, which has excellent rust prevention ability in saline-alkali soil containing corrosive substances. A spring with an elastic coefficient of K≈0.4 N / mm is sufficient.

[0024] Under external traction, multiple sets of deep loosening toothed plates 22 move in the compacted layer of the soil, breaking the compacted layer to form a soil trench, and then injecting a soil conditioner into the trench. The height of the conical bottom of the deep loosening toothed plate 22 is divided into three gradient types: 10-15cm, 15-20cm, and 20-25cm, respectively, for slightly salinized, moderately salinized, and severely salinized soils. The length of the entire deep loosening toothed plate 22 is 30-50cm, and the angle of the conical structure at the rear of the deep loosening toothed plate 22 is between 15° and 30°. If the cone angle is too large, it will affect the soil breaking effect; if it is too small, it will result in insufficient width of the soil trench.

[0025] A cylindrical deep-loosening tooth mounting column 3 is installed on the front side of the deep-loosening frame plate 2. The two ends of the deep-loosening tooth mounting column 3 are rotatably connected to the front side of the deep-loosening frame plate 2 through the mounting column pivot 4. The deep-loosening frame plate 2 is provided with mounting column pivot 4 at both ends. The rear end of the mounting column pivot 4 is fixed to the surface of the deep-loosening frame plate 2. The deep-loosening tooth mounting column 3 is rotatably connected to the mounting column pivot 4, so that the entire deep-loosening tooth mounting column 3 can rotate. To ensure the stability of the deep loosening tooth mounting column 3 after rotation, a pivot positioning protrusion 5 is fixedly connected to the bottom of both ends of the deep loosening frame plate 2, and a mounting column extension plate 6 is fixedly connected to both ends of the deep loosening tooth mounting column 3. The mounting column extension plate 6 and the deep loosening tooth mounting column 3 are combined to form a U-shaped structure. Positioning holes are provided on both the pivot positioning protrusion 5 and the mounting column extension plate 6. When both the mounting column extension plate 6 and the deep loosening tooth mounting column 3 are attached to the surface of the deep loosening frame plate 2, the positioning holes on the surface of the pivot positioning protrusion 5 are aligned with the positioning holes on the surface of the mounting column extension plate 6. By inserting bolts through the aligned positioning holes, the deep loosening tooth mounting column 3 and the deep loosening frame plate 2 can be fixed, thereby limiting and fixing the deep loosening tooth mounting column 3.

[0026] The deep loosening tooth mounting post 3 has an inner groove 16 inside, corresponding to the number of deep loosening tooth plates 22. The top of each deep loosening tooth plate 22 is connected to a sliding mounting plate 17 that slides laterally along the inner groove 16. The inner groove 16 consists of two parts: a cylindrical cavity and a waist hole communicating with the cylindrical cavity. A portion of the sliding mounting plate 17 extends into the cylindrical cavity, while the other portion extends outward through the waist hole, allowing the sliding mounting plate 17 to slide laterally within the inner groove 16. The sliding mounting plate 17 has a mounting plate slot 19 on its surface away from the inner groove 16 of the mounting post. The mounting plate slot 19 is a rectangular slot, and the insertion direction of the mounting plate slot 19 is located on the side of the sliding mounting plate 17 away from the inner groove 16 of the mounting post. A cylindrical toothed plate top post 21 is fixedly provided on the top of the deep loosening toothed plate 22. The diameter of the toothed plate top post 21 is smaller than the groove width of the mounting plate slot 19, and multiple sets of top posts are fixedly provided on the surface of the toothed plate top post 21 at equal intervals along the longitudinal direction. The horizontal insert plate 20, the width of which is smaller than the groove width of the mounting plate slot 19, and the groove shape of the horizontal insert plate 20 and the mounting plate slot 19 are adapted to each other, so that the horizontal insert plate 20 can be inserted laterally into the groove of the mounting plate slot 19 to complete the initial connection between the sliding mounting plate 17 and the horizontal insert plate 20; positioning holes are provided on the surfaces of both the horizontal insert plate 20 and the sliding mounting plate 17. After the horizontal insert plate 20 is inserted into the mounting plate slot 19, the positioning holes of the horizontal insert plate 20 and the sliding mounting plate 17 are aligned. The positioning holes of the mounting plate 17 are aligned. At this time, the sliding mounting plate 17 and the top column horizontal insert plate 20 are locked and reinforced by bolts, thereby completing the positioning and installation of the deep loosening tooth plate 22. When the sliding mounting plate 17 moves laterally in the groove 16 of the mounting column, it can drive the deep loosening tooth plate 22 to move laterally. During the forward movement of the deep loosening tooth plate 22, through the reciprocating movement left and right, the soil can be broken at the same time in the space on both sides directly in front of the deep loosening tooth plate 22, thereby increasing the width of the soil trench and increasing the air channels in the soil.

[0027] To achieve the lateral movement of the deep loosening toothed plate 22, a servo motor 7 is installed on the deep loosening frame plate 2, and the servo motor 7 is fixedly mounted on top of the deep loosening frame plate 2 by a bracket. The servo motor 7 requires an external power supply, and existing control technology is used to operate it. The output end of the servo motor 7 is connected to a functional rotating main disk 8, which can drive the functional rotating main disk 8 to rotate. Figure 3As shown, the functional rotating main disk 8 has an external structure divided into two parts. One part is a central disc-shaped structure, and the other part is an arc-shaped protrusion symmetrically arranged on both sides of the disc-shaped structure. The functional rotating main disk 8 is slidably connected to a sliding block part 11. Specifically, a concave rotating disk outer groove 9 is provided in the middle of the side wall of the functional rotating main disk 8. The groove shape of the rotating disk outer groove 9 is consistent with the external shape of the functional rotating main disk 8. A side groove is also provided on the side of the rotating disk outer groove 9. The top of the sliding block part 11 is slidably connected to the rotating disk outer groove 9 and the side groove. The bottom of the sliding block part 11 is located outside the functional rotating main disk 8 and is fixedly connected to an adjusting upright plate part 10. An upright plate limiting sleeve 12 is sleeved in the middle area of ​​the adjusting upright plate part 10, and one end of the upright plate limiting sleeve 12 is fixedly connected to the bracket on the top of the deep loosening frame plate 2. The upright plate limiting sleeve 12 provides longitudinal sliding limit for the adjusting upright plate part 10.

[0028] Due to the special shape of the functional rotating main disk 8, when the servo motor 7 drives the functional rotating main disk 8 to rotate, the sliding block part 11 slides along the outer groove 9 of the rotating disk. When the arc-shaped protrusion of the functional rotating main disk 8 rotates to the lower position, it will apply downward pressure to the sliding block part 11, causing the adjusting plate part 10 to move downward under the constraint of the plate limiting sleeve 12. Conversely, when the sliding block part 11 gradually disengages from the arc-shaped protrusion of the functional rotating main disk 8, the adjusting plate part 10 is pulled upward, thereby realizing the longitudinal reciprocating drive of the adjusting plate part 10; in the adjusting plate part 10 A plug-in pressure plate 13 is fixedly connected to the bottom, and the surface of the plug-in pressure plate 13 is provided with two sets of insertable through holes; a linkage main rod 15 is connected to each of the two sets of through holes. Specifically, a positioning horizontal insert 14 is fixedly connected to one end of the linkage main rod 15; the positioning horizontal insert 14 is rotatably connected to the corresponding through hole, and the positioning horizontal insert 14 drives the linkage main rod 15 to rotate; a synchronous connecting plate 18 is rotatably connected to the end of the linkage main rod 15 away from the positioning horizontal insert 14, and the bottom of the synchronous connecting plate 18 is fixedly connected to the top of a plurality of sliding mounting plates 17 on the same side.

[0029] Specifically, the front end of the positioning horizontal insert 14 is located outside the through hole of the insertion pressure plate 13. The front end of the positioning horizontal insert 14 is provided with a threaded part. The linkage main rod 15 and the positioning horizontal insert 14 can be locked with a nut to complete the connection of the linkage main rod 15.

[0030] When the insertion pressure plate 13 moves down, the linkage main rod 15 pushes the synchronous connecting plate 18, thereby causing the sliding mounting plate 17, which is fixedly connected to the synchronous connecting plate 18, to move within the mounting column groove 16, thus realizing the lateral movement of the horizontally arranged deep loosening toothed plates 22; the speed of the lateral reciprocating movement of the deep loosening toothed plates 22 is 0.1-0.5m / s.

[0031] like Figure 9As shown, a horizontal chute is provided at the bottom of the discharge chamber 25. An intercepting horizontal plate 33 is slidably connected within the chute, and both ends of the intercepting horizontal plate 33 are fixedly provided with side-top protrusions 34. The height of the side-top protrusions 34 gradually increases from the side closer to the discharge chamber 25 to the side farther away from the discharge chamber 25. Side grooves adapted to the side-top protrusions 34 are provided on both sides of the chute. The modifier inside the discharge chamber 25 can pass through the chute and enter the connection port at the bottom of the discharge chamber 25. By moving the intercepting plate 33 laterally within the chute, the modifier can be intercepted. When the intercepting plate 33 is pulled out laterally, the connection port of the discharge chamber 25 opens, allowing material to be discharged. Conversely, when the intercepting plate 33 completely closes the chute, the material supply can be paused. The side grooves on both sides of the chute are used for the movement of the side protrusion 34 of the plate, and the bottom of the side groove is designed to be inclined to minimize the impact of the modifier on the sliding of the intercepting plate 33 and the side protrusion 34 within the chute and side groove.

[0032] A material pushing plate 41 is installed above the intercepting horizontal plate 33 and on the surface of the discharge chamber 25. The material pushing plate 41 has a fan-shaped cross-section, and one side of the material pushing plate 41 is hinged to a hole opened on the surface of the discharge chamber 25. When the material pushing plate 41 rotates outward from the discharge chamber 25, one side of the material pushing plate 41 will block the hole opened on the surface of the discharge chamber 25. The presence of the material pushing plate 41 has little impact on the material discharge inside the discharge chamber 25. When the material pushing plate 41 rotates inward from the discharge chamber 25, the material pushing plate 41 will squeeze the modifier in the discharge chamber 25 downward, assisting the material discharge and improving the discharge effect of the modifier.

[0033] To achieve the movement of the aforementioned intercepting plate 33 and material pushing plate 41, the rotation of the functional rotating main disk 8 is used as the power source. Specifically, a longitudinally mounted trigger plate part 31 is provided on one side of the functional rotating main disk 8. A supporting and fixing side plate 28 is provided on the bottom side of the trigger plate part 31. The side of the supporting and fixing side plate 28 is fixedly connected to the surface of the deep loosening frame plate 2. A side plate transverse groove part 29 is opened on the surface of the supporting and fixing side plate 28. A transverse groove sliding block 30 extending into the groove of the side plate transverse groove part 29 is fixedly connected to the bottom of the trigger plate part 31. The transverse groove sliding block 30 can slide laterally within the side plate transverse groove part 29. A locking screw hole portion 26 with a circular array distributed at the front end of the functional rotating main disk 8 is provided. A limiting mounting plate portion 27 is attached to the surface of the functional rotating main disk 8. One end of the limiting mounting plate portion 27 has a positioning hole adapted to the locking screw hole portion 26. By attaching the limiting mounting plate portion 27 to the surface of the functional rotating main disk 8 and aligning the positioning hole of the limiting mounting plate portion 27 with the locking screw hole portion 26, the limiting mounting plate portion 27 can be fixed to the surface of the functional rotating main disk 8 after a bolt is inserted. A disc structure is provided at the other end of the limiting mounting plate portion 27. The disc structure of the limiting mounting plate portion 27 intermittently collides and contacts one side of the trigger upright plate portion 31. A trigger horizontal push rod portion 32 is connected to the other side of the trigger upright plate portion 31. The trigger horizontal push rod portion 32 is connected to the intercepting horizontal plate 33. By moving the trigger upright plate portion 31 laterally, the intercepting horizontal plate 33 can be moved laterally.

[0034] When the main rotating disk 8 rotates, the horizontal groove sliding block 30, which was originally located on the right side of the side plate horizontal groove 29, is pushed to the left side of the side plate horizontal groove 29 by the rotation of the limiting mounting plate 27. This causes the trigger upright plate 31 to move to the left. At this time, the trigger horizontal push rod 32 connected to the trigger upright plate 31 can simultaneously drive multiple sets of intercepting horizontal plates 33 to move. A spring is connected between the inner wall of the side plate horizontal groove 29 and the horizontal groove sliding block 30. When the limiting mounting plate 27 rotates and disengages from the surface of the trigger upright plate 31, the spring releases elastically, pushing the trigger upright plate 31 to the initial position, thus completing the directional movement of the intercepting horizontal plate 33. This enables the intercepting horizontal plate 33 to open and close the internal channel of the discharge chamber 25.

[0035] Since the locking screw holes 26 are distributed in a ring, different numbers of limiting mounting plates 27 can be installed at the locking screw holes 26 according to actual usage requirements, thereby changing the triggering frequency of the trigger plate 31.

[0036] A top-mounted top protrusion 34 of the horizontal plate is slidably connected to a top-mounted top protrusion slider 35. A groove is formed on the side of the top-mounted top protrusion 34, and a portion of the top-mounted top protrusion slider 35 slides within the groove. A toggle block 36 is fixedly provided on the top of the top-mounted top protrusion slider 35. The toggle block 36 has a triangular structure, with one side being a sloping surface of the triangle. A convex-shaped groove is provided on the sloping surface. A limiting horizontal plate 37 is symmetrically fixedly provided on the side wall of the discharge chamber 25. A sliding groove is provided on the limiting horizontal plate 37, and a sliding component is slidably connected within the sliding groove of the limiting horizontal plate 37. A horizontal plate inner moving block 38 is provided with a sliding adapter block 39 at one end. One end of the sliding adapter block 39 is a cylindrical structure, and the other end of the sliding adapter block 39 is a U-shaped groove structure. The cylindrical structure and the U-shaped groove structure are connected by an L-shaped connecting rod. One end of the cylindrical structure is fixedly connected to the horizontal plate inner moving block 38, and the side wall of the cylindrical structure is slidably connected to the convex sliding groove on the corresponding actuating top block 36. The material pushing plate 41 is rotatably connected to a rotating actuating vertical plate 40 through a rotating shaft. The end of the rotating actuating vertical plate 40 away from the material pushing plate 41 is inserted into the U-shaped groove structure of the sliding adapter block 39.

[0037] A longitudinal groove is provided on the surface of the discharge chamber 25, and a slider embedded in the longitudinal groove is provided on the surface of the actuating top block 36. The slider and the longitudinal groove provide a limit for the longitudinal movement of the actuating top block 36.

[0038] As the side-top protrusion 34 of the horizontal plate moves into the discharge chamber 25, it lifts the actuating block 36, causing it to move longitudinally upwards. Meanwhile, the sliding adapter block 39, under the lateral constraint of the inner moving block 38 of the horizontal plate, gradually moves away from the discharge chamber 25 as the actuating block 36 moves upwards. The U-shaped groove structure of the sliding adapter block 39 pulls the rotating actuating plate 40, thereby causing the material pushing plate 41 to rotate. At this time, the material pushing plate 41 gradually leaves the internal channel of the discharge chamber 25, while the intercepting horizontal plate 33 is laterally inserted into the discharge chamber 25, sealing the connection port at the bottom of the discharge chamber 25. Conversely... When the top protrusion 34 of the horizontal plate is pulled out from the discharge chamber 25, the top protrusion adapter slider 35 falls, causing the top block 36 to move downward. The cylindrical structure of the sliding adapter block 39 moves along the sliding groove of the limiting horizontal plate 37 to the side closer to the discharge chamber 25. Then, through the U-shaped groove structure of the sliding adapter block 39, it pushes the rotating vertical plate 40 to move in the opposite direction, thereby pushing the material push plate 41 to rotate. At this time, the intercepting horizontal plate 33 is located outside the discharge chamber 25, the connection port at the bottom of the discharge chamber 25 is opened, the material push plate 41 enters the discharge chamber 25 and squeezes the modifier downward, and the modifier enters the connection port at the bottom of the discharge chamber 25.

[0039] In summary, by rotating the main rotating disk 8, the deep loosening toothed plate 22 is driven to move laterally and reciprocally. At the same time, the intercepting horizontal plate 33 closes and stops the internal channel of the discharge chamber 25, and drives the material pushing plate 41 to rotate. When the intercepting horizontal plate 33 is open, the improver in the discharge chamber 25 is pushed.
