Description

Technical Field

[0001] The invention relates to the technical field of pest control in granaries, and in particular to an aluminum phosphide residue treatment device. Background Art

[0002] When the pest infection of grains (including finished grains, raw grains, oilseeds, dried potatoes, seed grains, etc.) reaches a certain level, a certain amount of aluminum phosphide, calcium phosphide, zinc phosphide, DDT and other drugs are buried in the grain pile under sealed conditions. The above-mentioned phosphides can absorb moisture in the gaps in the grain pile and in the grain, produce a chemical reaction, and release highly toxic phosphine gas, so as to kill various pests and insect eggs in the grain pile.

[0003] Among them, common grain fumigation generally uses pelletized aluminum phosphide, which is inserted into the grain pile through a tube and a rod. The tube is about 1 to 3 meters long, and the rod is located in the tube. The rod is taken out to make the tube hollow, and then the pelletized aluminum phosphide is delivered to the grain pile to fumigate the grain.

[0004] After searching, a patent with authorization announcement number CN220140641U discloses a grain fumigation ring dispenser, including a bracket, a rotating rod is rotatably connected to the upper part of the bracket, a wire roller is fixedly connected to the middle part of the rotating rod, a steel wire rope is arranged on the outer periphery of the wire roller, a pipe cap is arranged on the lower end of the steel wire rope, a medicine tube is threadedly connected to the lower part of the pipe cap, a cone head is threadedly connected to the bottom of the medicine tube, a plurality of evenly distributed inclined holes are arranged on the outer periphery of the upper part of the medicine tube, a bottom plate is fixedly connected to the bottom of the bracket, a lifting port is arranged in the middle part of the bottom plate, a cross fixing rod is fixedly connected to the inner side of the cone head, a limiting rod is fixedly connected to the middle part of the bracket, and the bracket, rotating rod, limiting rod and bottom plate are all made of galvanized material. The dosing device can achieve the purpose of accurate dosing without space restriction, environmental protection and zero pollution through the coordination of the rotating rod, wire roller, wire rope, pipe cap, medicine tube, cone head and inclined hole. However, the dosing device is to load a plurality of pelletized aluminum phosphide into the medicine tube. After the aluminum phosphide in the medicine tube is volatilized, the medicine tube needs to be taken out from the grain. During the removal process, since the medicine tube has an inclined hole, it is easy to cause the aluminum phosphide residue to run out of the inclined hole and contact the grain. At the same time, the residual gas of the aluminum phosphide residue drifts out from the inclined hole and is easily absorbed by the human body, causing an impact.

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] like Figures 1 to 15As shown, the present invention provides an aluminum phosphide residue processing device, including a sleeve inserted in the grain, a material conveying pipe 300 communicating with the inner cavity of the sleeve is arranged at the upper end of the sleeve, a plurality of air holes 120 for gas circulation are evenly arranged on the sleeve, a spiral sheet 140 is coaxially arranged inside the sleeve, that is, the spiral sheet 140 is a rectangular rod, and two spiral guide grooves are respectively arranged on both sides of the rectangular rod, and a transmission rod 400 is inserted and installed inside the sleeve, and the diameter of the transmission rod 400 is adapted to the inner diameter of the inner cylinder 110, and the circumference of the transmission rod 400 is opened from top to bottom. There is a spiral groove 410, and a plurality of accommodating grooves 420 are arranged at intervals in the spiral groove 410. There is a transition arc surface between the accommodating groove 420 and the spiral groove 410. The inner diameter of the accommodating groove 420 is adapted to the pelletized aluminum phosphide and is larger than the width of the spiral groove 410. The inner diameter of the spiral groove 410 is smaller than the outer diameter of the pelletized aluminum phosphide. A spiral sleeve 460 is arranged in the transmission rod 400, which is used in conjunction with the spiral piece 140 and drives the transmission rod 400 to rotate; when the transmission rod 400 is sleeved on the outside of the spiral piece 140 and moves downward, the transmission rod 400 rotates synchronously during the descent.

[0023] A collecting cylinder 430 with an annular collecting opening on the top is coaxially arranged at the lower end of the conveying rod 400, and a circular hole 433 matched with the outer diameter of the spiral sheet 140 is opened in the middle of the collecting cylinder 430 to facilitate the passage of the spiral sheet 140; a pressing handle 440 is passed through and rotatably connected to the upper end of the conveying rod 400. In detail, the pressing handle 440 is connected to the conveying rod 400 by a bearing to ensure that the pressing handle 440 no longer rotates with the conveying rod 400 during the rotating and descending process of the conveying rod 400. A cleaning ring 500 is coaxially arranged inside the opening of the upper end of the sleeve below the pressing handle 440 and is sleeved on the upper section of the conveying rod 400. The cleaning ring 500 is slidably connected to the conveying rod 400. A scraper 520 for processing the residue in the receiving groove 420 is arranged on the inner wall of the cleaning ring 500. When the conveying rod 400 moves upward and leaves the cleaning ring 500, the scraper 520 moves along the spiral groove 410 on the conveying rod 400 to scrape off the residue in the spiral groove 410 and the receiving groove 420.

[0024] When the above scheme is used, first, the pelletized aluminum phosphide is stored in the feeding pipe 300; then the sleeve is inserted into the grain pile; and then the conveying rod 400 is inserted into the sleeve; when the conveying rod 400 enters the sleeve and moves downward, the conveying rod 400 can be rotated and moved downward from top to bottom through the cooperation between the spiral sheet 140 and the spiral sleeve 460. At the same time, after the receiving groove 420 on the conveying rod 400 corresponds to the feeding pipe 300, since the outer diameter of the pelletized aluminum phosphide is larger than the inner diameter of the spiral groove 410 and smaller than the inner diameter of the receiving groove 420, The pelletized aluminum phosphide can only roll when it contacts the spiral groove 410, and can enter and be stored in the containing groove 420 only when the pelletized aluminum phosphide moves to the containing groove 420, thereby finally realizing the automatic unloading of the pelletized aluminum phosphide and distributing it at intervals in the inner cylinder 110, and cooperating with a plurality of air holes 120 to realize the uniform volatilization of the pelletized aluminum phosphide and the uniform dispersion of the gas generated, and being able to isolate the pelletized aluminum phosphide from the grain, so as to facilitate the collection of the aluminum phosphide residue after volatilization, thereby solving the problem that the pelletized aluminum phosphide is retained in the grain after volatilization and cannot be processed. Among them, when the conveying rod 400 is taken out from the sleeve, the scraper 520 on the cleaning ring 500 enters into the receiving groove 420 along the spiral groove 410. Since the position of the cleaning ring 500 is fixed, the scraper 520 is always located in the spiral groove 410 of the conveying rod 400 during the rotation process, thereby cleaning the residues in the spiral groove 410 and the receiving groove 420, and then collecting the residues in the receiving groove 420 into the collecting tube 430, thereby reducing the need for manual cleaning and effectively preventing harmful gases in the residues from being inhaled by the human body.

[0025] In this embodiment, a circular groove 450 having a depth matching the height of the spiral piece 140 is opened axially upward at the bottom end of the transmission rod 400, a spiral sleeve 460 is axially arranged in the circular groove 450, and the spiral sleeve 460 is fixedly arranged in the bottom opening of the circular groove 450, and a spiral rectangular hole matching the circumference of the spiral piece 140 is arranged in the spiral sleeve 460, that is, two protrusions matching the spiral guide groove of the spiral piece 140 are arranged in the rectangular hole, and the gap between the two protrusions matches the spiral guide groove of the spiral piece 140. The two protrusions can respectively adapt to the spiral guide grooves on both sides of the spiral piece 140 and drive the spiral sleeve 460 to rotate; with the cooperation of the spiral piece 140 and the spiral sleeve 460, when the spiral sleeve 460 in the conveying rod 400 is sleeved on the outside of the spiral piece 140 and the conveying rod 400 moves downward, the spiral piece 140 can drive the spiral sleeve 460 to rotate, thereby driving the conveying rod 400 to rotate synchronously during the descent process, so as to cooperate with the conveying pipe 300, the spiral groove 410 and the receiving groove 420 to carry out intermittent feeding of the pelletized aluminum phosphide.

[0026] like Figure 2 and Figure 4As shown, in order to further prevent the leakage of pelletized aluminum phosphide residues into the grain while ensuring that the pelletized aluminum phosphide can effectively kill insects, the present invention controls the closing and opening states of the air holes 120 on the sleeve to achieve communication and relative sealing between the inner cavity of the sleeve and the outside world. In this embodiment, the sleeve includes an outer cylinder 100, an inner cylinder 110 and an installation sleeve 200. The inner cylinder 110 is rotatably arranged in the outer cylinder 100, and the outer wall of the inner cylinder 110 is in contact with the inner wall of the outer cylinder 100. The upper ends of the outer cylinder 100 and the inner cylinder 110 are both set to be open, and a plurality of air holes 120 are evenly and symmetrically arranged on the inner cylinder 110 and the outer cylinder 100. In the initial state, the positions of the air holes 120 on the inner cylinder 110 and the outer cylinder 100 are staggered, and the inner cavity of the inner cylinder 110 is not connected to the outside. When the inner cylinder 110 and the outer cylinder 100 are relatively rotated at a set angle, the air holes 120 on the inner cylinder 110 and the outer cylinder 100 correspond to each other one by one, and the inner cylinder The inner cavity of 110 is connected to the outside; the installation sleeve 200 is coaxially connected and connected to the outer cylinder 100, and an adaptive positioning ring 130 is arranged along the circumference of the connection, and the cleaning ring 500 is arranged in the upper opening of the installation sleeve 200; the feeding pipe 300 is fixed to one side of the upper end of the installation sleeve 200 and is connected to the inner cavity of the installation sleeve 200; the positioning ring 130 is used to support and limit the sleeve inserted into the grain pile, so that the outer cylinder 100 and the inner cylinder 110 below the positioning ring 130 are inside the grain pile, and the installation sleeve 200, the feeding pipe 300, the cleaning ring 500 and the pressing handle 440 above the positioning ring 130 are located outside the grain pile, which is convenient for installation and use; like Figure 2 and Figure 6 As shown, in order to align the air holes 120 on the outer cylinder 100 and the inner cylinder 110 by rotating the outer cylinder 100 and the inner cylinder 110 at a set angle (the rotation angle is five to ten degrees), in this embodiment, the lower end of the spiral piece 140 is fixedly connected to the inner cylinder 110; a guide groove 101 is opened at the lower inner side of the outer cylinder 100 along the circumferential direction, and a positioning column 111 sliding in the guide groove 101 is provided on the outer wall of the lower end of the inner cylinder 110. The cooperation between the positioning column 111 and the guide groove 101 can make the inner cylinder 110 only rotate at a set angle relative to the outer cylinder 100 to limit the position, so as to cooperate with the external force to realize the communication or relative sealing between the inner cavity of the inner cylinder 110 and the outside through the relative rotation of the outer cylinder 100 and the inner cylinder 110.

[0027] In detail, during use, the upper end of the handheld transmission rod 400 is firstly held and sent downward into the inner cylinder 110 through the mounting sleeve 200. When the spiral sleeve 460 at the lower end of the transmission rod 400 is inserted into the spiral piece 140 of the inner cylinder 110, since the handheld transmission rod 400 does not rotate, the spiral piece 140 is driven to drive the inner cylinder 110 to rotate forwardly by a set angle. At this time, the air holes 120 on the outer cylinder 100 and the inner cylinder 110 are aligned to realize the conduction between the inner cavity of the inner cylinder 110 and the outside; then Loosen the upper end of the conveying rod 400 and hold the pressure handle 440 to continue to push the conveying rod 400 downward. Since the spiral piece 140 cannot continue to rotate further after rotating to the limit position with the inner cylinder 110, the conveying rod 400 will continue to rotate forward relative to the inner cylinder 110 and the pressure handle 440 during the descent process with the cooperation of the spiral piece 140 and the spiral sleeve 460, thereby realizing the intermittent feeding of the pelletized aluminum phosphide. During use, the pelletized aluminum phosphide can volatilize and enter the grain pile through the air vent 120 to achieve effective insecticide.

[0028] When the pelletized aluminum phosphide needs to be replaced after a set period of use, first, the upper end of the conveying rod 400 is held and lifted upward. At this time, since the conveying rod 400 held by hand does not rotate, the spiral piece 140 is driven to drive the inner cylinder 110 to rotate in the opposite direction by a set angle. At this time, the air holes 120 on the outer cylinder 100 and the inner cylinder 110 are misaligned to achieve a relative sealing between the inner cavity of the inner cylinder 110 and the outside world; then, the upper end of the conveying rod 400 is loosened and the pressing handle 440 is held to continue to lift the conveying rod 400. Since the spiral piece 140 rotates with the inner cylinder 1 10 is reversed to the limit position and cannot continue to rotate, so the conveying rod 400 will continue to rotate in the opposite direction relative to the inner cylinder 110 and the pressing handle 440 during the ascending process under the cooperation of the spiral sheet 140 and the spiral sleeve 460. When the spiral groove 410 and the receiving groove 420 on the conveying rod 400 pass through the scraping member 520 on the inner wall of the cleaning ring 500, the pelletized aluminum phosphide residue in the spiral groove 410 and the receiving groove 420 will be scraped off and descend along the spiral groove 410 or fall directly downward, and finally collected in the collecting cylinder 430. Since the inner cavity of the inner cylinder 110 is relatively sealed with the outside world during this process, the pelletized aluminum phosphide residue can be effectively prevented from leaking into the grain through the air vent 120.

[0029] like Fig. 9 and Fig.10 As shown, a limit groove 210 adapted to the cleaning ring 500 is provided on the upper end surface of the mounting sleeve 200, and the limit groove 210 can limit the circumferential movement of the cleaning ring 500 to prevent it from moving; in order to ensure that the cleaning ring 500 does not move upward along with the conveying rod 400 during the rising process of the conveying rod 400, one or more sets of position locking mechanisms are arranged between the mounting sleeve 200 and the cleaning ring 500, which can limit the axial movement and circumferential rotation of the cleaning ring 500 to prevent it from moving.

[0030] In this embodiment, the position locking mechanism can adopt a pin 201, the outer end of the pin 201 is provided with a limit ring 202 and the inner end is provided with an upward guiding inclined surface, the pin 201 passes through the tube wall of the installation sleeve 200 and the guiding inclined surface is located in the inner cavity of the installation sleeve 200, and the outer wall of the cleaning ring 500 is correspondingly provided with a pin hole 502; a spring 203 is sleeved on the surface of the pin 201 between the outer wall of the installation sleeve 200 and the limit ring 202, and the two ends of the spring 203 are respectively fixed to the limit ring 202 and the outer wall of the installation sleeve 200, and the guiding inclined surface of the spring 203 is located in the inner cavity of the installation sleeve 200 in the original length state, that is, the spring 203 always drives the pin 201 to move inward; In the initial state, the cleaning ring 500 is sleeved on the conveying rod 400 and is located between the collecting tube 430 and the pressing handle 440. After the spiral sleeve 460 of the conveying rod 400 is inserted into the spiral sheet 140 of the inner tube 110 through the circular hole 433, the cleaning ring 500 is placed in the limiting groove 210 and contacts the guiding inclined surface at the outer end of the pin 201. As the conveying rod 400 is driven downward, the cleaning ring 500 descends and squeezes the guiding inclined surface, thereby driving the pin 201 to overcome the elastic force of the spring 203 and move outward. When the pin 201 corresponds to the position of the pin hole 502 on the outer wall of the cleaning ring 500, the spring 203 drives the pin 201 to enter the pin hole 502, thereby locking the position of the cleaning ring 500.

[0031] When the conveying rod 400 is taken out, after the collecting tube 430 at the lower end of the conveying rod 400 presses against the lower end of the cleaning ring 500, the cleaning ring 500 and the collecting tube 430 can be taken out of the housing together by pulling out the pin 201.

[0032] like Fig.14 and Fig.15As shown, in this embodiment, the position locking mechanism can also use two clamping plates 230 symmetrically arranged in the limiting groove 210, and the cleaning ring 500 is provided with a clamping groove 530 used in conjunction with the clamping plate 230. The cooperation between the clamping plate 230 and the clamping groove 530 can limit the axial movement of the position of the cleaning ring 500, so as to prevent the cleaning ring 500 from following the rise of the transmission rod 400 and causing the inner cylinder 110 to fail to form a closed space. The limiting groove 210 is provided with two symmetrically arranged installation cavities 220, and the clamping plate 230 is elastically arranged in the installation cavity 220. In detail, both sides of the lower end of the clamping plate 230 are connected with connecting rods 231, and the connecting rod 231 is located in the installation cavity 220. A torsion spring 232 is fixedly connected between the connecting rod 231 and the installation cavity 220. The upper end of the clamping plate 230 is provided with a clamping joint 233, and the cross section of the clamping joint 233 is triangular, and the shape of the clamping joint 233 is adapted to the shape of the clamping groove 530. The clamping joint 233 has a first inclined surface 234 and a second inclined surface 235. The second inclined surface 235 is arranged so that the cleaning ring 500 can lift the clamping plate 230, so that the clamping plate 230 enters the clamping groove 530 to fix the position of the cleaning ring 500. The arrangement of the first inclined surface 234 can push the cleaning ring 500 out of the mounting sleeve 200 after the collecting tube 430 contacts the cleaning ring 500. The inclination angle of the first inclined surface 234 is greater than the inclination angle of the second inclined surface 235, so that the resistance of the cleaning ring 500 is increased when it is moved out of the mounting sleeve 200, thereby preventing the cleaning ring 500 from easily slipping out of the mounting sleeve 200.

[0033] In the initial state, the cleaning ring 500 is sleeved on the conveying rod 400 and is located between the collecting tube 430 and the pressing handle 440. After the spiral sleeve 460 of the conveying rod 400 is inserted into the spiral sheet 140 of the inner tube 110 through the circular hole 433, the cleaning ring 500 is placed in the limiting groove 210 and contacts the second inclined surface 235 of the clamping joint 233. As the conveying rod 400 is driven downward, when the cleaning ring 500 descends and squeezes through the second inclined surface 235, the clamping plate 230 is driven to overcome the elastic force of the torsion spring 232 and swing. When the clamping joint 233 on the clamping plate 230 corresponds to the position of the clamping groove 530, the torsion spring 232 resets and drives the clamping joint 233 to enter the clamping groove 530, thereby locking the position of the cleaning ring 500.

[0034] When taking out the conveying rod 400, after the collecting tube 430 at the lower end of the conveying rod 400 presses against the lower end of the cleaning ring 500, the cleaning ring 500 is subjected to force through the clamping joint 233 and the first inclined surface 234, driving the clamping plate 230 to overcome the elastic force of the torsion spring 232 and swing, so that the cleaning ring 500 and the collecting tube 430 can be taken out of the shell together.

[0035] like Figure 7 and Fig. 9As shown, the scraper 520 is always located in the spiral groove 410 and initially located at the uppermost end of the spiral groove 410. The scraper 520 includes a bristle bundle 550 and a sponge cover 540 arranged at the outer end of the bristle bundle 550; the outer end of the bristle bundle 550 is bundled and the inner end is freely dispersed, the outer diameter of the outer end of the bristle bundle 550 is smaller than the width of the spiral groove 410, the length of the outer end of the bristle bundle 550 is adapted to the depth of the spiral groove 410, and the outer diameter of the outer end of the bristle bundle 550 after the sponge cover 540 is set is larger than the width of the spiral groove 410; the area of ​​the bristles at the inner end of the bristle bundle 550 in a free state is larger than the area of ​​the receiving groove 420, and the length of the bristles at the inner end of the bristle bundle 550 in a free state is larger than the depth of the receiving groove 420; The outer end of the bristle bundle 550 always moves along the spiral groove 410, and the spiral groove 410 is cleaned by the expandable and contractible sponge cover 540, and the outer end of the bristle bundle 550 can play a good supporting role; the bristles at the inner end of the bristle bundle 550 are in a bent state when in the spiral groove 410, and when the bristle bundle 550 moves to the receiving groove 420, the bristles at the inner end of the bristle bundle 550 are freely expanded to clean the receiving groove 420; with the relative movement of the scraper 520 and the conveying rod 400, the aluminum phosphide residues in the spiral groove 410 and the receiving groove 420 can be cleaned by the sponge cover 540 and the bristle bundle 550.

[0036] like Figure 3 , Figure 7 and Figure 8 As shown, in order to be able to automatically block the collection tube 430 when the collection tube 430 is removed, in the present invention, a ring cover plate 510 is detachably provided at the lower end of the cleaning ring 500, and the outer diameter of the ring cover plate 510 is adapted to the inner diameter of the inner tube 110, and the ring cover plate 510 is used to block the annular collection opening at the upper end of the collection tube 430; a clamping groove 501 is provided at the lower end of the cleaning ring 500, and a clamping piece 511 used in conjunction with the clamping groove 501 is fixedly connected to the upper end surface of the ring cover plate 510, and the clamping groove 501 is connected to the clamping piece 511. The cooperation between the connectors 511 can realize the detachable connection between the ring cover plate 510 and the cleaning ring 500. During the cleaning process, the positions of the ring cover plate 510 and the cleaning ring 500 can be relatively fixed to avoid obstruction of the annular collecting opening at the upper end of the collecting tube 430 due to the downward movement of the ring cover plate 510. After cleaning, the ring cover plate 510 can seal the annular collecting opening at the upper end of the collecting tube 430 and can be separated from the cleaning ring 500, so as to facilitate further processing of the collecting tube 430 containing aluminum phosphide residue.

[0037] like Figure 7 and Figure 8As shown, in this embodiment, the snap-in groove 501 includes a guide hole and an arc-shaped slide groove, and the snap-in component 511 includes an anti-slip portion at the upper end and a sliding rod at the lower end. The area of ​​the anti-slip portion is smaller than the guide hole and larger than the arc-shaped slide groove. After the anti-slip portion of the snap-in component 511 is inserted into the guide hole, the ring cover plate 510 is rotated to realize the coaxial connection between the ring cover plate 510 and the cleaning ring 500.

[0038] like Fig.12 As shown, in this embodiment, the outer wall of the collecting barrel 430 contacts the inner wall of the inner barrel 110, and the collecting barrel 430 is provided with an annular storage cavity 432, and the upper end surface of the storage cavity 432 is provided with an annular collection opening, and the side wall of the annular collection opening is provided with a convex ring 434 with an end surface inclined inwardly, and the convex ring 434 is made of a flexible material, such as a rubber convex ring, and can be inserted into the annular collection opening at the lower end of the ring cover plate 510 through deformation and compression of the lower end of the ring cover plate 510, so as to realize the closure of the annular collection opening at the upper end of the collecting barrel 430 through the ring cover plate 510. The upper end surface of the convex ring 434 is inclined inwardly, which is conducive to the faster entry of the residues swept from the conveying rod 400 into the storage cavity 432 of the collecting barrel 430.

[0039] like Figure 2 , Figure 7 , Figure 8 and Fig.12 As shown, in order to realize the disassembly of the collecting barrel 430, so that the collecting barrel 430 storing the aluminum phosphide residue can be further processed, in the present invention, a mounting ring 431 is fixedly connected to the collecting barrel 430, and the mounting ring 431 is threadedly connected to the lower end of the conveying rod 400, and the mounting ring 431 is threadedly connected to the conveying rod 400. After the circumferential surface of the mounting ring 431 and the conveying rod 400 are threadedly connected, it is flush to avoid blocking the residue from entering the storage cavity 432. In this embodiment, the inner surface of the mounting ring 431 is provided with an internal thread, the outer diameter of the lower end of the conveying rod 400 is reduced and provided with an external thread, and the mounting ring 431 and the thread are installed at the lower end of the conveying rod 400, and the circumferential surface is flush.

[0040] The mounting ring 431 and the transmission rod 400 may also be connected by a snap-fit ​​connection (the snap-fit ​​connection adopts the existing technology and will not be described in detail here).

[0041] In the present invention, the lower end of the ring cover plate 510 can be squeezed by deformation of the convex ring 434 to achieve sealing of the ring cover plate 510 on the collecting tube 430; the ring cover plate 510 and the mounting ring 431 can also be threadedly connected to achieve sealing of the collecting tube 430 by the ring cover plate 510; in this embodiment, the inner wall of the ring cover plate 510 is provided with an internal thread, and the outer wall of the mounting ring 431 is provided with a corresponding external thread. After the ring cover plate 510 contacts the collecting tube 430, the collecting tube 430 is rotated by the transmission rod 400, thereby achieving threaded connection between the ring cover plate 510 and the mounting ring 431.

[0042] After the ring cover 510 seals the collecting cylinder 430, the axial and circumferential movement restrictions of the cleaning ring 500 are cancelled through the position locking mechanism, and the cleaning ring 500, the ring cover 510, the collecting cylinder 430 and the conveying rod 400 are taken out of the outer cylinder 100 together. Then, the collecting cylinder 430 is rotated to separate the collecting cylinder 430, the cleaning ring 500 and the ring cover 510 from the conveying rod 400. Finally, the collecting cylinder 430 is rotated to drive the ring cover 510 to rotate together. The collecting cylinder 430 and the ring cover 510 can be removed from the cleaning ring 500 by disengaging the clamping piece 511 on the ring cover 510 from the clamping groove 501 on the cleaning ring 500, so as to facilitate further processing of the aluminum phosphide residue in the collecting cylinder 430.

[0043] like Figure 1 and Fig.13 As shown, in order to allow aluminum phosphide to be transported into the inner cylinder 110 at intervals, a mounting groove 330 is provided inside the feeding pipe 300, a rotating roller 340 is rotatably installed inside the mounting groove 330, and a plurality of accommodating grooves 350 are provided at equal intervals in the circumferential direction of the rotating roller 340. A feeding pipe 310 corresponding to the rotating roller 340 is connected to the top of the feeding pipe 300, and the feeding pipe 310 is connected to an external storage device. A driver 320 is installed on one side of the feeding pipe 300, and a rotating shaft on the driver 320 passes through the feeding pipe 300 and is coaxially fixedly connected with the rotating roller 340. The accommodating groove 350 on the rotating roller 340 can intermittently transport the pelletized aluminum phosphide, and at the same time, after the rotating roller 340 has transported the pelletized aluminum phosphide, the rotating roller 340 blocks the feeding pipe 300 to prevent the gas generated during the volatilization of the pelletized aluminum phosphide from escaping from the feeding pipe 300. In detail, in order to move the pelletized aluminum phosphide on the rotating roller 340 to the containing tank 420 as quickly as possible, the outlet end of the conveying pipe 300 is configured as a downwardly inclined surface.

[0044] In the present invention, considering that the volume of the sleeve inserted in the grain is relatively large, the length of the sleeve can generally reach 1 meter to 3 meters, and the diameter of the sleeve can be 15 centimeters to 25 centimeters, which has sufficient space for structural design optimization. Therefore, the present invention adopts a multi-layer nesting design, that is, the outer cylinder 100, the inner cylinder 110, and the spiral piece 140 are nested in sequence, and the spiral piece 140 and the spiral sleeve 460 cooperate to make the conveying rod 400 rotate synchronously during the descent process, and the pelletized aluminum phosphide is discharged at intervals; when the conveying rod 400 enters the inner cylinder 110, the upper end of the conveying rod 400 is held and rotated, and the spiral piece 140 is driven by the spiral sleeve 460 to drive the inner cylinder 110 to rotate forward, so that the air holes 120 on the outer cylinder 100 and the inner cylinder 110 are aligned to realize the conduction between the inner cavity of the inner cylinder 110 and the outside world; when the conveying rod 400 is moved out of the inner cylinder 110, the upper end of the conveying rod 400 is held and lifted upward, and the spiral piece 140 is driven by the spiral sleeve 460 to drive the inner cylinder 110 to rotate in the opposite direction, so that the air holes 120 on the outer cylinder 100 and the inner cylinder 110 are misaligned to realize the relative sealing between the inner cavity of the inner cylinder 110 and the outside world.

[0045] In the present invention, after the aluminum phosphide residue is collected and processed, considering that toxic phosphine gas may remain after the aluminum phosphide is fumigated, which is likely to pose a threat to the environment and human health, a reaction tank used in conjunction with an aluminum phosphide collection sleeve is provided, a stirring rod is installed inside the reaction tank, a multi-speed regulating motor connected to the stirring rod is installed at the bottom of the reaction tank to regulate the stirring speed of the stirring rod, a water storage tank connected to the reaction tank body is installed above the reaction tank body, and a copper heating pipe is installed in the water storage tank for heating water. An aluminum phosphide residue pouring port is provided above the reaction tank body, and a sealing cover is installed on the pouring port. Four phosphine gas processors and two pressure relief valves are installed above the reaction tank, and activated carbon is installed in the phosphine gas processor to absorb harmful gases. A remote-controlled electric regulating ball valve is provided below the tank body, and a remote-controlled electric regulating ball valve is installed in the middle of the pipeline connecting the water storage tank and the reaction tank. During use, the aluminum phosphide residue is first collected and poured into the reaction tank, and then the boiling water in the water storage tank is remotely injected into the reaction tank. The stirring rod is driven by the remote control motor to stir the aluminum phosphide and boiling water evenly. After sufficient reaction, the waste water after the reaction is finally discharged into the wastewater pool through the ball valve switch controlled by the remote control, thus completing the entire operation and ensuring that no secondary pollution is generated during the treatment process. The aluminum phosphide residue can be treated quickly and effectively, reducing treatment costs and time.

[0046] Working principle of the present invention: When in use, the outer cylinder 100 is first inserted from the top of the granary into the grain, the outer cylinder 100 goes deep into the grain, the installation sleeve 200 protrudes from the horizontal surface of the grain, and then the transmission rod 400 enters the inner cylinder 110 from the installation sleeve 200, and the spiral piece 140 contacts the spiral sleeve 460. Under the cooperation of the spiral piece 140 and the spiral sleeve 460, the transmission rod 400 rotates and moves toward the bottom of the inner cylinder 110; At the same time, the pelletized aluminum phosphide enters the conveying pipe 300 through the feeding pipe 310, and the pelletized aluminum phosphide is located in the containing groove 350 on the rotating roller 340. When the containing groove 420 on the conveying rod 400 corresponds to the outlet of the conveying pipe 300, the pelletized aluminum phosphide enters the containing groove 420, and the pelletized aluminum phosphide is sequentially conveyed to the inner cylinder 110; After the transmission rod 400 enters the inner cylinder 110, the cleaning ring 500 is fixed by the position locking mechanism to prevent the cleaning ring 500 from rotating and moving; When the spiral sleeve 460 contacts the spiral piece 140, the spiral sleeve 460 drives the spiral piece 140 to rotate a certain angle, so that the air holes 120 on the inner cylinder 110 and the outer cylinder 100 correspond to each other, thereby realizing the opening of the air holes 120 on the sleeve, so that the gas generated by the volatilization of the pelletized aluminum phosphide can contact the grain; After the fumigation of the pelletized aluminum phosphide is completed, the pelletized aluminum phosphide is a block of slag and is located in the containing tank 420; The conveying rod 400 is lifted by the pressing handle 440, and the conveying rod 400 will rotate in the opposite direction again under the cooperation of the spiral sleeve 460 and the spiral sheet 140, so that the inner cylinder 110 rotates a certain angle, and then the air holes 120 on the inner cylinder 110 and the outer cylinder 100 are staggered, so that the air holes 120 on the inner cylinder 110 are closed. Since the position of the cleaning ring 500 does not move, a closed space is formed between the collecting cylinder 430 and the cleaning ring 500 during the ascending process of the conveying rod 400 to prevent the aluminum phosphide residue and the gas that has not been completely volatilized from being absorbed by the human body. At the same time, the scraper 520 on the cleaning ring 500 enters the receiving groove 420 from the spiral groove 410, and the residue in the receiving groove 420 falls downward into the storage cavity 432 on the collecting cylinder 430, so as to clean the residue in the receiving groove. When the collecting barrel 430 contacts the ring cover plate 510, the ring cover plate 510 closes the feed port of the storage chamber 432 on the collecting barrel 430, and then the collecting barrel 430 is twisted to separate the collecting barrel 430 from the conveying rod 400. At the same time, the threads on the collecting barrel 430 and the ring cover plate 510 correspond, and the collecting barrel 430 rotates to separate the clamping piece 511 from the clamping groove 501, thereby separating the cleaning ring 500 from the ring cover plate 510, thereby realizing the connection between the collecting barrel 430 and the ring cover plate 510, and closing the storage chamber 432 of the disassembled collecting barrel 430 to prevent the gas in the storage chamber 432 from leaking out.
