Description

Technical Field

[0001] The invention belongs to the technical field of agricultural production, and relates to a device for crushing and separating waste ground films, in particular to a device for crushing and separating agricultural waste ground films and a separation method thereof. Background Art

[0002] Ground mulch is difficult to degrade naturally, and its residue in the fields will cause "white pollution". Waste ground mulch remaining in the soil will destroy the soil structure, reduce soil moisture absorption and permeability, and affect crop emergence and root growth. By recycling waste ground mulch, we can reduce plastic residues in the soil and protect the soil ecology. After recycling, waste ground mulch can be processed into new plastic products or raw materials to achieve resource recycling. However, waste ground mulch will be stained with soil, straw, etc. after use. If it is not effectively separated, the material will be difficult to use during the secondary production process.

[0003] After searching, for example, Chinese patent documents disclose an agricultural straw processing and recycling device with a film separation function [Application No.: 202210991614.5; Publication No.: CN115351034B]. This device removes the residual film from the raw material straw by setting a screening and filtering device, separates the residual film from the straw fragments through a filter plate, and then sends the filtered film waste to a waste recovery device through a three-sided transmission plate for subsequent processing. At the same time, the vibrating impact wheel will continuously impact the filter plate, so that the waste on the filter plate can be sent to the waste recovery device faster to ensure that there is no film waste residue in the crushed straw.

[0004] Although the agricultural straw processing and recycling device with mulch film separation function disclosed in this patent can separate mulch film from straw, the core technology of the agricultural straw processing and recycling device with mulch film separation function is to achieve separation through screening, filtration and vibration, and the mulch film has a certain slight stickiness. The straw fragments are attached to the mulch film through static electricity and other means, and it is difficult to completely filter out. Moreover, the mulch film screened out by vibration alone is still in a state of being stained with a lot of soil and other dirt, and still needs to be processed for subsequent recycling.

[0007] The working principle of the present invention is as follows: a linear motor is used to drive the waste ground film to move to different positions for cleaning, drying and crushing respectively; a clamping mechanism is used to clamp the waste ground film; a cleaning mechanism is used to clean the clamped waste ground film; a drying mechanism is used to dry after cleaning; a cutting mechanism performs preliminary cutting of the ground film before the ground film enters the crusher body; after the preliminary cutting, the ground film is kept clean and free of debris before entering the crusher body; there is no need to manually transfer the ground film, thus saving manpower and labor, avoiding debris from causing wear and damage to the internal structure of the crusher body, and extending the service life of the crusher body; and after crushing, the ground film is clean and pollution-free for easy use; the preliminary cutting improves the cutting efficiency of the crusher body and avoids The mulch film is too long and causes the parts inside the crusher body to be entangled. The clamping bar is moved upward to compress the spring, and one end of the waste mulch film is passed through the clamping bar and the clamping frame. The two ends of the clamping bar are loosened, and the spring restoring force causes the clamping bar to move downward, so that the waste mulch film is clamped and fixed between the clamping bar and the clamping frame. When the linear motor drives the body to move above the cleaning mechanism, the second electric telescopic rod is extended to allow the waste mulch film to enter the cleaning mechanism. The second motor drives the clamping frame to rotate, and the waste mulch film rotates in the clean water with the clamping frame. At the same time, the second electric telescopic rod is repeatedly extended and retracted, and the waste mulch film rotates up and down in the water, which is fully cleaned to remove debris. The third motor and the electric thermal cutting wire are both existing technologies, and the cleaning The washed and dried waste mulch is moved to the top of the crusher body by the linear motor, and the third motor drives the circular plate to rotate, and the center of rotation is different from the center of the circular plate, so that the rotation range of the circular plate is expanded.

During the sliding process, the rotating wheel rotates in the slide groove, reducing friction and accelerating the movement of the push plate. The push plate pushes the debris in the sedimentation bottom frame to accelerate into the filter frame, so that the debris can be dumped more thoroughly.

The filter screen is placed on the limit bar to filter out excess mud and water, and the filter screen can be taken out of the filter frame, avoiding manual transfer, saving manpower labor, saving time and effort, and at the same time avoiding the situation where water-stained debris is difficult to clean during the transfer process.

[0020] A feeding mechanism is arranged above the transmission mechanism, and the feeding mechanism includes a fixed cover, a revolving door is rotatably connected to the right side of the fixed cover, a fourth electric telescopic rod is fixed to the top of the inner wall of the fixed cover, a connecting cross plate is fixed to the bottom end of the fourth electric telescopic rod by bolts, electromagnets are fixed to the left and right ends of the bottom of the connecting cross plate, the electromagnets are magnetically connected to the magnetic suction block, the filter screen can be in contact with the fixed cover and the revolving door on all sides, an air supply mechanism is arranged on the top of the fixed cover, the air supply mechanism includes a connecting frame fixed between the fixed cover and the mounting frame, a second blower is fixed in the connecting frame by bolts, a single outlet air duct is connected to the output end of the second blower, an end of the single outlet air duct away from the second blower is fixed to the left side of the fixed cover, a blocking net is fixed between the single outlet air duct and the fixed cover, and a diversion mechanism is arranged between the second blower and the single outlet air duct.

[0021] With the above structure, when the filter frame is located directly below the fixed cover, the fourth electric telescopic rod is extended to make the electromagnet close to the magnetic block. After the bottom of the electromagnet is aligned with the top of the magnetic block, the electromagnet is operated. The electromagnet is magnetically connected to the magnetic block, and the fourth electric telescopic rod is retracted. The connecting cross plate moves up with the fourth electric telescopic rod, the electromagnet moves up with the connecting cross plate, the magnetic block moves up with the electromagnet, and the filter moves up with the magnetic block into the fixed cover. Under the premise that the second blower is connected to the inside of the fixed cover, the second blower enters the fixed cover through the through holes on the right side and the bottom of the three-way box and the round hole on the top of the fixed cover in turn, and blows Solid debris on the surface of the dry filter is removed, and the retaining net prevents lighter debris such as straw fragments from entering the single-outlet air duct. After the debris is dried, the outlet of the second blower is connected to the single-outlet air duct and the revolving door opening through the diversion mechanism. The external collection bag is pasted on the revolving door opening, and the second blower blows the lighter debris (mostly straw and other plants) into the external collection bag for subsequent secondary utilization. Heavier debris such as gravel remains on the filter and is thrown into the soil or reused. The debris contaminated on the waste is screened by wind to extract its value, avoiding the debris from occupying the workshop's garbage disposal space as garbage, which is environmentally friendly.

[0022] The diversion mechanism includes a three-way box, wherein through holes are provided on the left and right sides and the bottom of the three-way box, the left through hole is connected to the single-outlet air duct, the right through hole is connected to the second blower output end, and the bottom through hole is connected to the circular hole opened on the top of the fixed cover.

[0023] With the above structure, the first gear and the second gear have the same number of teeth. When the air outlet of the second blower on the fixed cover needs to be changed, the fifth motor drives the first rotating shaft and the first synchronous wheel to rotate, and the baffle rotates 90° clockwise with the first rotating shaft, that is, blocks the through hole at the bottom of the three-way box, so that the air can be discharged from the left side of the fixed cover. The baffle rotates 90° counterclockwise, that is, blocks the through hole on the left side of the three-way box, so that the air can be discharged from the top of the fixed cover.

[0024] A separation method of a device for crushing and separating agricultural waste mulch film, the method is a method for using the device for crushing and separating agricultural waste mulch film, and the steps are as follows: Step 1: clamping, clamping the waste mulch film between the clamping strip and the clamping frame; Step 2: Cleaning: Pour clean water into the water frame to the upper / linear position inside the water frame, and the linear motor drives the body to translate until the body and the cleaning mechanism are on the same vertical horizontal line. The second electric telescopic rod drives the clamped waste mulch film into the clean water, and the second motor drives the clamping frame to rotate. At the same time, the second electric telescopic rod keeps retracting, so that the waste mulch film rotates up and down in the clean water for cleaning; the speed is 50rmp, and the cleaning time is 10min; Step 3: Remove and dry, the second electric telescopic rod retracts, the waste mulch is separated from the sewage, the linear motor drives the body to move between the crusher body and the water frame, and the first blower blows the wet waste mulch through the double outlet air duct and the inclined bottom air duct in turn until it is dried; Step 4: Preliminary crushing and complete crushing. The linear motor drives the machine body to move above the crusher body. The cutting mechanism preliminarily cuts the waste mulch film. After the preliminary cutting, the mulch film enters the crusher body and is completely crushed. The completely crushed mulch film is recycled for secondary use. Step 5: Sedimentation. After cleaning the waste mulch, the sewage is precipitated in the water frame for 1.5 hours. After sedimentation is completed, the butterfly valve is opened to discharge the sewage through the drain pipe. At this time, the fourth motor drives the lead screw to rotate, and the threaded transmission between the slider and the lead screw moves the filter frame to the limited position of the positioning plate on the left. The first electric telescopic rod retracts, and the sedimentation bottom frame moves down. The first motor indirectly drives the sedimentation bottom frame to rotate clockwise. The push plate slides on the sedimentation bottom frame toward the filter frame due to gravity, pushing the sewage and debris into the filter frame; Step 6: Filtration, the debris enters the filter frame and is separated into solid and liquid by the filter screen, and at the same time, the fourth motor rotates in the opposite direction to move the filter frame to the position limited by the right positioning plate; Step 7: Drying. The fourth electric telescopic rod is extended to make the running electromagnet approach the magnetic block and attract it. After attraction, the fourth electric telescopic rod retracts, and the filter enters the fixed cover from the bottom along with the magnetic block. At this time, the revolving door is in a vertically closed state, and the baffle is in a vertical state to expose the bottom through hole of the three-way box. The second blower blows air once through the bottom through hole of the three-way box and the round hole on the top of the fixed cover to dry the debris until it is completely dried. Step eight: Screening. After drying, the fifth motor indirectly drives the baffle to rotate 90° clockwise to cover the bottom hole of the three-way box and expose the left hole. At the same time, the revolving door opens counterclockwise, and the collection bag is pasted on the revolving door opening and the fixed cover. The second blower blows air through the three-way box and the single-outlet air duct in turn, and the dried straw and other plants are blown into the collection bag, and heavier debris such as gravel remains on the surface of the filter. The screened straw and other plants can be reused.

[0025] Compared with the prior art, the agricultural waste mulch film crushing and separation device and separation method have the following advantages: 1. Fix one end of the waste mulch by the clamping mechanism, wash it in a water frame, blow it dry with the first blower, and make preliminary cutting with the electric heating cutting wire by reciprocating up and down and left and right. After a series of treatments, put the waste mulch into the crusher body to make it clean and free of debris after crushing, improve the quality of secondary utilization materials, simplify the subsequent secondary utilization operation steps, and avoid dirt, straw, gravel and other debris entering the crusher, avoid the crusher from being worn and damaged by contact with debris, and improve the service life of the crusher body. At the same time, the waste mulch is initially crushed before entering the crusher body, which improves the crushing efficiency and avoids the accident of long mulch wrapping around parts during the crushing process, further improving the service life of the crusher.

[0026] 2. A linear motor is provided to provide power for left and right linear motion, so that the waste mulch film is clamped by the clamping frame and the clamping bar, and the second electric telescopic rod is extended and retracted, and the second motor rotates to wash the waste mulch film up and down in the clean water. The second electric telescopic rod retracts and the linear motor drives the connecting plate to move left, so that the waste mulch film is separated from the clean water and dried by the first blower. The linear motor continues to drive the connecting plate to move left to the active range of the electric heating cutting wire, so that the waste mulch film is initially crushed. In this process, except for fixing the waste mulch film between the clamping frame and the clamping bar, no manual operation is required, which saves manpower and keeps the operator away from the waste mulch film to reduce dust inhalation and away from the crusher body, thereby reducing the personal safety risk in the process of crushing the waste mulch film and improving safety.

[0027] 3. By setting a third motor to drive the circular plate to rotate away from the center of the circular plate itself, cooperating with the connecting rod transmission of the single-hole rotating plate, the first double-hole rotating plate, the three-hole rotating plate, and the second double-hole rotating plate, as well as the engagement of the limit slot plate with the mounting sliding block and the connecting trapezoidal block with the trapezoidal slot of the fixed plate, the movement trajectory limitation in the left and right straight lines and the up and down straight lines can be achieved, and a motor can indirectly drive the electric thermal cutting wire to move repeatedly up and down and left and right, so that the movement trajectory of the electric thermal cutting wire is complicated, the cutting frequency of the waste mulch is faster, the specifications of the waste mulch after preliminary crushing are smaller, and the crushing efficiency is improved.

[0028] 4. The sewage is allowed to settle by means of the sedimentation mechanism. After the debris is deposited on the sedimentation bottom frame, the sewage is discharged through the drain pipe, and the sewage is separated into solid and liquid to achieve preliminary sewage treatment, thereby avoiding blockage of the sewage discharge system of the waste film processing workshop. The sedimentation bottom frame indirectly driven by the first electric telescopic rod and the first motor is used to dump the debris and perform subsequent screening, thereby exploring the possibility of debris utilization and improving the environmental value. The rotating wheel and the push plate are used to slide when the sedimentation bottom frame is tilted to push the debris, so that the debris can be moved to the filter more thoroughly and quickly, thereby improving the operating efficiency.

[0029] 5. The filter frame and the filter screen are transported to the limited positions of the left and right positioning plates through the transmission mechanism. The first electric telescopic rod and the first motor control the sedimentation bottom frame to dump the debris. The fourth electric telescopic rod, the electromagnet and the magnetic suction block pull up the filter screen, so that the debris enters the filter frame and the fixed cover respectively, and the filtering, drying and screening steps are carried out, so that the debris does not need to be manually transferred in multiple steps, saving manpower and labor, and avoiding the situation where the wet debris is difficult to clean during the transfer process.

[0030] 6. Through the diversion mechanism, the fifth motor can indirectly drive the rotation of the baffle and the revolving door at the same time, changing the path of the second blower blowing air into the fixed cover. When the wind blows out from the top of the fixed cover, the liquid in the debris can be blown out from the bottom of the filter, speeding up the drying speed. When the wind blows out from the left side of the fixed cover, it is directly aimed at the external collection bag, so that lighter objects can enter the collection bag more accurately, thereby improving the utilization rate of wind power.

[0031] 7. By adding the steps of cleaning, drying and preliminary crushing before the waste mulch enters the crusher body, the secondary raw materials of the waste mulch after crushing are cleaner and of better quality, reducing the subsequent secondary utilization steps, improving the quality of the items after secondary utilization, improving the crushing efficiency, reducing the entry of debris into the crusher body, and extending the service life of the crusher body.

A linear motor 15 is fixed between the bracket 8 and the mounting frame 10 by bolts, and a connecting plate 301 is fixed to the output end of the linear motor 15. There are two connecting plates 301, and a top plate 302 is integrally formed on the top of the two connecting plates 301. A clamping mechanism 4 is arranged on the top plate 302, and a drying mechanism 5 is arranged on the side of the top plate 302. A cleaning mechanism 2 is arranged on the right side below the linear motor 15, and a crusher body 6 is placed on the left side below the linear motor 15, and a cutting mechanism 7 is arranged on the crusher body 6.

[0053] In this embodiment, the linear motor 15 and the crusher body 6 are both prior arts. The linear motor 15 is used to drive the waste ground film to move to different positions for cleaning, drying and crushing respectively. The clamping mechanism 4 is used to clamp the waste ground film. The cleaning mechanism 2 is used to clean the clamped waste ground film. The drying mechanism 5 is used to dry after cleaning. The cutting mechanism 7 performs preliminary cutting of the ground film before it enters the crusher body 6. After the preliminary cutting, the ground film remains clean and free of debris before entering the crusher body 6. There is no need to manually transfer the ground film, which saves manpower and labor, avoids wear and damage to the internal structure of the crusher body 6 caused by debris, and extends the service life of the crusher body 6. After crushing, the ground film is clean and pollution-free for easy use. The preliminary cutting improves the cutting efficiency of the crusher body 6 and avoids the ground film being too long and causing the parts inside the crusher body 6 to be entangled.

[0054] The clamping mechanism 4 includes a second electric telescopic rod 401, a mounting frame 402 is fixed at the bottom end of the second electric telescopic rod 401, a second motor 403 is fixed in the mounting frame 402, and the output end of the second motor 403 is connected to the bottom of the mounting frame 402, the output end of the second motor 403 is keyed to a clamping frame 404, and slide grooves are provided on both sides of the clamping frame 404, a clamping bar 405 is passed through the slide groove, and a spring 406 is fixed between the clamping bar 405 and the top of the inner wall of the clamping frame 404.

[0055] In this embodiment, the second electric telescopic rod 401 and the second motor 403 are both prior arts. The clamping bar 405 is moved upward to compress the spring 406, and one end of the waste mulch is passed through the clamping bar 405 and the clamping frame 404. The two ends of the clamping bar 405 are loosened, and the restoring force of the spring 406 causes the clamping bar 405 to move downward, so that the waste mulch is clamped and fixed between the clamping bar 405 and the clamping frame 404. When the linear motor 15 drives the body 3 to move above the cleaning mechanism 2, the second electric telescopic rod 401 is extended to allow the waste mulch to enter the cleaning mechanism 2, and the second motor 403 drives the clamping frame 404 to rotate, and the waste mulch rotates in the clean water with the clamping frame 404. At the same time, the second electric telescopic rod 401 is repeatedly extended and retracted, and the waste mulch rotates up and down in the water, which is fully cleaned to remove debris.

[0056] The cutting mechanism includes a fixed plate 701 fixed at an upper position in front of the crusher body 6, a third motor 702 is fixed to the front end of the fixed plate 701, and the output end of the third motor 702 is connected to the rear end of the fixed plate 701, a circular plate 703 is keyed to the output end of the third motor 702, a position of the front end of the circular plate 703 away from the center of the circle is keyed to the output end of the third motor 702, a single-hole rotating plate 704 is fixedly connected to the position of the rear end of the circular plate 703 away from the center of the circle, the single-hole rotating plate 704 is rotatably connected to the first double-hole rotating plate 705 at one end away from the circular plate 703, and the first double-hole rotating plate 705 is rotatably connected to the three-hole rotating plate 706 at one end away from the single-hole rotating plate 704, and a fixed The short rod on the fixed plate 701 and the three-hole rotating plate 706 rotate around the short rod as the center of the circle. The end of the three-hole rotating plate 706 away from the first double-hole rotating plate 705 is rotatably connected to the second double-hole rotating plate 707. The end of the second double-hole rotating plate 707 away from the three-hole rotating plate 706 is rotatably connected to the installation sliding block 708. The bottom of the installation sliding block 708 is trapezoidally engaged with a limiting groove plate 711. The bottom of the limiting groove plate 711 is fixed with a connecting trapezoidal block 710.

A movable ring 709 is fixed to the bottom of the connecting trapezoidal block 710. The movable ring 709 is sleeved on the circular plate 703. The top of the installing sliding block 708 is fixed with an electric heating cutting wire 712.

[0057] In this embodiment, the third motor 702 and the electric hot cutting wire 712 are both prior arts. The cleaned and dried waste mulch is moved to the top of the crusher body 6 by the linear motor 15. The third motor 702 drives the circular plate 703 to rotate, and the center of rotation is different from the center of the circular plate 703, so that the rotation range of the circular plate 703 is expanded. The movable ring 709 can only move linearly up and down due to the limitation of the connecting trapezoidal block 710 and the trapezoidal groove. The movable ring 709 moves linearly up and down with the circular plate 703. The single-hole rotating plate 704 rotates with the circular plate 703, the first double-hole rotating plate 705 rotates with the single-hole rotating plate 704, the three-hole rotating plate 706 rotates with the first double-hole rotating plate 705, the three-hole rotating plate 706 rotates with the short rod on the fixed plate 701 as the center, and the second double-hole rotating plate 707 rotates with the three-hole rotating plate 706. The bottom of the sliding block 708 is a trapezoid, and the trapezoid is aligned with the top of the limiting slot plate 711. The trapezoidal grooves are interlocked, and the interlocking relationship limits the moving trajectory of the installation sliding block 708. The installation sliding block 708 moves linearly left and right with the second double-hole rotating plate 707. At the same time, the limiting groove plate 711 moves up and down with the connected trapezoidal block 710, so that the installation sliding block 708 repeatedly moves up and down and left and right with the limiting groove plate 711. The electric thermal cutting wire 712 realizes repeated up and down and left and right movements with the installation sliding block 708. The electric thermal cutting wire 712 cuts the waste ground film during the movement. After cutting, the ground film falls into the crusher body 6 for complete crushing. The third motor 702 and multiple rotating plates form a connecting rod movement to complicate the trajectory of the electric thermal cutting wire 712, speed up the cutting frequency of the electric thermal cutting wire 712, and make the waste ground film after preliminary cutting smaller in size, share the crushing work of the crusher body 6, avoid excessively long waste ground film from being entangled with the internal parts of the crusher body 6, and extend the service life of the crusher body 6.

The cleaned and dried waste mulch film is moved to the top of the crusher body 6 by the linear motor 15. The third motor 702 drives the circular plate 703 to rotate, and the center of rotation is different from the center of the circular plate 703, so that the rotation range of the circular plate 703 is expanded. The movable ring 709 is limited by the connection between the trapezoidal block 710 and the trapezoidal groove and can only move linearly up and down. The movable ring 709 moves linearly up and down with the circular plate 703.

After the debris in the single-outlet air duct 1303 is dried, the air outlet of the second blower 1302 is connected to the single-outlet air duct 1303 and the opening of the revolving door 1202 through the diversion mechanism 14, and the fifth motor 1402 drives the first rotating shaft 1403 and the first synchronous wheel 1405 to rotate. The baffle 1404 rotates 90° clockwise with the first rotating shaft 1403, that is, blocks the bottom through hole of the three-way box 1401, so that the air can be discharged from the left side of the fixed cover 1201. The baffle 1404 rotates 90° counterclockwise, that is, blocks the left through hole of the three-way box 1401, so that the air can be discharged from the top of the fixed cover 1201.
