Description

Technical Field

[0001] The present invention relates to the technical field of predatory mite breeding equipment, and in particular to an indoor predatory mite breeding device and an operating method. Background Art

[0002] The main function of predatory mites is to control pests, especially red spider mites. Predatory mites are carnivorous pest mites that feed on pests such as red spiders and will not cause harm to plants. They can effectively control the number of pests and reduce the use of chemical pesticides, thereby ensuring the quality and safety of agricultural products. In the process of raising predatory mites, compared with outdoor raising, indoor raising is more conducive to controlling the temperature and humidity during the raising of predatory mites, which greatly increases the survival rate and survival time of predatory mites.

[0003] The existing method of raising predatory mites is usually to raise predatory mites and spider mites in the same space. The predatory mites use spider mites as bait to prey on them and thus feed them. The specific method is to use the spider mite's host plant to raise spider mites, and then use the raised spider mites to raise predatory mites. However, if this breeding method is used in the same container, the reproduction rate of spider mites and predatory mites cannot be guaranteed. If the predatory mites hunt too quickly, the predatory mites in the container will instantly lose their hunting targets, so the spider mites need to be re-cultivated. Since it takes many days to re-raise spider mites, the predatory mites are always in a state of waiting to be preyed during this period. Therefore, spider mites and predatory mites need to be raised separately. However, raising them separately is inconvenient during the feeding process and is not conducive to observation.

[0004] In order to solve the above problems, a device and an operating method are proposed for conveniently raising spider mites and predatory mites at the same time and conveniently feeding spider mites. Summary of the Invention

[0005] In response to the above-mentioned problems, the present invention provides an indoor predatory mite breeding device and operating method, which solves the existing method of breeding predatory mites, which is usually to place predatory mites and spider mites in the same space for breeding, and the predatory mites use spider mites as feed bait to prey on them to achieve feeding. The specific method is to use the spider mite host plant to breed spider mites, and then use the raised spider mites to breed predatory mites. However, if this breeding method is used in a container, the reproduction rate of the spider mites and the predatory mites cannot be guaranteed. If the predatory mites hunt too quickly, the predatory mites in the container will instantly lose their hunting targets, so the spider mites need to be re-cultivated. Since it takes many days to re-breed the spider mites, the predatory mites are always in a state of waiting to be preyed during this period. Therefore, the spider mites and the predatory mites need to be raised separately. However, when they are raised separately, it is inconvenient during the feeding process and it is not conducive to observation.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] refer to Figures 1 to 11 , an indoor predatory mite breeding device and operating method, comprising a barrel body 1, a culture barrel 5, a top cover 6, a connecting barrel 7, a transport box 18, a harvesting tray 11, a rotating cylinder 17, an arc-shaped baffle 12, a support leg 14, a first rotating mechanism, a second rotating mechanism, a lifting mechanism, and a sliding mechanism; The lower parts of the four walls of the barrel body 1 are connected to connecting barrels 7, and the other ends of the four connecting barrels 7 are connected to culture barrels 5. Three of the four culture barrels 5 are used to breed spider mites, and the other culture barrel 5 is used to breed predatory mites. The connecting barrels 7 are connecting parts between the four culture barrels 5 and the barrel body 1. The top walls of the four culture barrels 5 are respectively detachably mounted with top covers 6, which can be removed to observe, increase, or clean the organisms in the culture barrels 5; The lower ends of the four connecting barrels 7 are respectively fixed with supporting legs 14, which are used to support the equipment so that the barrel body 1 has a certain distance from the placement plane to facilitate the harvesting tray 11 to slide down; The four culture barrels 5 are each rotatably mounted with an arc-shaped baffle 12, and the four arc-shaped baffles 12 are detachably arranged between the connection barrel 7 and the connection between the culture barrel 5 and the four culture barrels 5; The four arc-shaped baffles 12 are all driven to rotate by the second rotating mechanism. Driven by the second rotating mechanism, the four arc-shaped baffles 12 can block the culture barrel 5 and the connecting barrel 7 adjacent thereto. A transport box 18 is movably mounted in each of the four connecting barrels 7. The four transport boxes 18 are driven to slide by a sliding mechanism. When the arc-shaped baffle 12 opens the communication channel between the culture barrel 5 and the connecting barrel 7, the transport boxes 18 will simultaneously slide into the connecting channel driven by the sliding mechanism, and eventually deliver the spider mites or predatory mites on them into the barrel body 1. The second rotating mechanism is driven to work by the sliding mechanism; A rotating drum 17 is rotatably mounted in the lower portion of the barrel body 1. Through holes 1701 are respectively provided on the four walls of the rotating drum 17. The four through holes 1701 are detachably connected to the adjacent connecting drums 7. The rotating drum 17 is driven to rotate by the first rotating mechanism. Driven by the first rotating mechanism, the rotating drum 17 can rotate and form a state of communication or closure between the four through holes 1701 and the four connecting barrels 7; The sliding mechanism is driven to work by the first rotating mechanism; A harvest tray 11 is movably mounted below the barrel 1. An inclined wall 1101 is mounted inside the harvest tray 11. The purpose of the harvest tray 11 is to collect spider mites or predatory mites at the lower part of the inclined wall, making it easier for predatory mites to prey on spider mites. The harvest tray 11 is driven by a lifting mechanism. The top wall of the harvest tray 11 is in detachable contact with the bottom wall of the barrel 1. When the harvest tray 11 is lowered, the predatory mites in the harvest tray 11 can be collected. When it is raised, it is convenient to feed the predatory mites being raised. The first rotating mechanism is driven to work by the lifting mechanism.

[0022] The lifting mechanism includes a driving column 3, a cross connecting rod 2, a housing 201, a return spring 20, a round table 301, and a button 4; A cross connecting rod 2 is installed on the top wall of the barrel body 1, and a driving column 3 is installed slidingly through the intersection of the horizontal rod and the vertical rod of the cross connecting rod 2; A button 4 is fixedly mounted on the upper end of the driving column 3, and the bottom wall of the button 4 is in detachable contact with the top wall of the cross connecting rod 2; The harvesting tray 11 is fixedly connected to the lower end of the driving column 3; The lower end of the cross connecting rod 2 is fixedly mounted with a housing 201, and the upper end of the driving column 3 is fixedly mounted with a round platform 301; The round table 301 is movably installed in the housing 201; The bottom wall of the truncated cone 301 is connected to the upper end of the bottom wall of the housing 201 via a return spring 20; The driving column 3 drives the first rotating mechanism to work by sliding. There is a section of thread on the driving column 3. When the device is in the initial state, the four connecting barrels 7 and the barrel body 1 are connected. The thread is located above the cross connecting rod 2. Figure 11 As shown in A, when the driving column 3 is pressed to make the thread contact with the screw teeth at the intersection of the horizontal plate and the vertical plate of the cross connecting rod 2, the driving column 3 is slightly rotated to make the screw teeth and the thread cooperate with each other to achieve fixation. Figure 11 As shown in B, at this time, the reset spring 20 is in and remains in a compressed state, and the driving column 3 drives the harvesting plate 11 below to slide out downward and can keep the harvesting plate 11 in this state for a long time. Since the four connecting barrels 7 can be in a closed state only when the harvesting plate 11 extends downward, and the four connecting barrels 7 need to be in a closed state for a long time during the subsequent breeding process to ensure that the four culture barrels 5 always maintain independent spaces, when the thread on the driving column 3 is threadedly connected to the horizontal and vertical plates of the cross connecting rod 2, the equipment can be fixed in this state. When the driving column 3 is rotated in the opposite direction to disengage the upward thread of the driving column 3 from the screw thread at the intersection of the horizontal plate and the vertical plate of the cross connecting rod 2, the reset spring 20 begins to lift the table 301 upward, and the driving column 3 fixedly mounted on the table 301 is lifted upward, and the harvesting plate 11 connected to the driving column 3 begins to lift upward and seal the bottom wall of the barrel body 1.

[0023] The first rotating mechanism includes a connecting plate 15, a first connecting rod 16, a guide post 21, and a slider; The middle end of the driving column 3 is rotatably sleeved with a connecting disk 15, which is installed below the sleeve 201; The first end of the first connecting rod 16 is fixedly mounted in the connecting disk 15; A spiral groove 102 is provided on the inner wall of the barrel body 1, and a slider is slidably installed in the spiral groove 102; The outer wall of the second end of the first connecting rod 16 is movably arranged between the slider; A guide post 21 is fixedly mounted on the top wall of the rotating cylinder 17; The guide post 21 is slidably arranged to penetrate the second end of the first connecting rod 16; The rotating cylinder 17 works by rotating to drive the sliding mechanism. As the driving column 3 moves up and down, the connecting disk 15 fixedly connected to the driving column 3 will also start to slide up and down. In the process of sliding up and down, the connecting disk 15 drives the first connecting rod 16 to start to move up and down. While the first connecting rod 16 moves up and down, it drives the slider at the end to start sliding along the spiral groove 102. The slider will slide up or up along the spiral groove and will start to rotate along the spiral groove. The first connecting rod 16 will also start to have the ability to rotate along with the slider, and the connecting disk 15 is also rotating on the driving column 3 at this time. During the rotation, the first connecting rod 6 will drive the guide column 21 to start rotating, and the rotating cylinder 17 fixedly connected to the guide column 21 starts to rotate. During the rotation, the rotating cylinder 17 can form a connection or closure with the four connecting barrels 7 respectively.

[0024] The sliding mechanism includes a first rectangular slider 1702, a second connecting rod 8, and a second rectangular slider 1801; The upper ends of the four walls of the rotating cylinder 17 are respectively fixed with first rectangular sliders 1702 , and the four first rectangular sliders 1702 are respectively installed in the middle of the upper part of two adjacent through holes 1701 ; The side wall of the barrel body 1 is provided with four arcuate through grooves 101 that cooperate with the first rectangular slider 1702 . The four arcuate through grooves 101 are all provided below the spiral groove 102 . The four first rectangular sliding blocks 1702 are respectively slidably arranged to penetrate the arc-shaped through slots 101 corresponding thereto; The upper ends of the four first rectangular sliders 1702 are respectively fixedly mounted with first connecting shafts, and the outer walls of the four first connecting shafts are respectively rotatably mounted with the first ends of the second connecting rods 8; The side walls of the four transport boxes 18 are respectively fixed with second rectangular sliders 1801, and the side walls of the four connecting barrels 7 are respectively provided with rectangular sliding grooves 701 that cooperate with the second rectangular sliders 1801; The four second rectangular sliding blocks 1801 are respectively slidably arranged to penetrate the corresponding rectangular sliding grooves 701; The upper ends of the four second rectangular sliders 1801 are respectively fixed with second connecting shafts; The second ends of the four second connecting rods 8 are respectively rotatably sleeved on the outer wall of the second connecting shaft adjacent thereto; The four second rectangular sliders 1801 drive the second rotating mechanism to work by sliding respectively. When the rotating cylinder 17 rotates, it also drives the four first rectangular sliders 1702 fixed thereto to start rotating along the four arc-shaped through grooves 101. When the four first rectangular sliders 1702 rotate, they will respectively drive the second connecting rods 8 close to them to start deflecting. When the four second connecting rods 18 deflect, they will respectively drive the second rectangular sliders 1801 to start sliding along the rectangular through grooves 701 that cooperate with them. The transport box 18 fixedly connected to the four second rectangular sliders 1801 can now start to slide back and forth. It should be noted that when the rotating cylinder 17 rotates to connect the barrel body 1 with the connecting barrel 7, the four transport boxes 8 will slide into the barrel body 1 from this connection. When the rotating cylinder 17 rotates and gradually closes the connecting barrel 7, the transport box 8 gradually slides backward into the connecting barrel 7. During this process, there is no interference between the transport box 8 and the rotating cylinder 7.

[0025] The second rotating mechanism includes a connecting plate 13, a spur gear 10, a rack plate 9, and a connecting block 19; The lower ends of the four second rectangular sliders 1801 are respectively fixed with connecting blocks 19, and the lower ends of the four connecting blocks 19 are respectively fixed with rack plates 9; The bottom walls of the four culture barrels 5 are respectively provided with spur gears 10 which are rotatably mounted via rotating shafts. The four spur gears 10 are respectively engaged with rack plates 9 adjacent thereto. The four rotating shafts rotate through the bottom wall of the culture barrel 5 adjacent to them and are equipped with a plurality of connecting plates 13; Several connecting plates 13 located in the same culture barrel 5 are fixedly connected to the arc-shaped baffle 12 close to it. During the reciprocating sliding process, the four second rectangular sliders 1801 will respectively drive the rack plate 9 fixed thereto through the connecting block 19 to start reciprocating sliding. The spur gear 10 engaged with the rack plate 9 can then start to rotate back and forth, and the arc-shaped baffle 12 fixedly installed coaxially with the spur gear 10 can start to rotate back and forth. It should be noted that when the arc-shaped baffle 12 rotates to close the culture barrel 5 and the connecting barrel, the transport box 8 just slides into the barrel body 1. When the arc-shaped baffle 12 rotates to connect the culture barrel 5, the rotating cylinder 17 just closes the barrel body 1, and the transport box 8 just slides into the connecting barrel 7. At this time, the culture barrel 5 and the connecting barrel 7 become a connecting space.

[0026] The horizontal rod and vertical rod of the cross connecting rod 2 are respectively connected to the top wall of the barrel body 1 through a detachable glass cover, which is used to facilitate the breeding personnel to observe through the glass cover, and also to facilitate the external light source to enter the barrel body 1 through the glass cover to provide a certain temperature and light for the predatory mites.

[0027] The two sides of the four second rectangular sliding blocks 1801 are connected to the two sides of the corresponding rectangular through slots 701 through flexible sealing members, and their function is to prevent predatory mites and spider mites from escaping from the two rectangular through slots 701 .

[0028] The operating method of the indoor predatory mite breeding device comprises the following steps: Step 1: Press the button 4 to separate the harvest box 11 from the bottom of the barrel body 1 and expose it. Slightly rotate the driving rod 3 to fix the driving rod 3 and the cross connecting plate 2 to each other. At this time, the four connecting barrels 7 located outside the side wall of the barrel body 1 remain in a closed state. A certain amount of feed can be placed in the harvest box 11. This part of the feed is used to feed the predatory mites. When the predatory mites and spider mites are all placed in the harvest box 11, the predatory mites will prey on the spider mites. After preying on the spider mites, they can continue to eat the feed, avoiding food shortages after predation; Step 2: Place a number of spider mites in three of the culture barrels 5, with the ratio of male to female spider mites being 1:1. This is to facilitate the self-reproduction of spider mites in the three culture barrels 5. Step 3: Place a number of predatory mites into the remaining culture bucket 5, with the ratio of male to female predatory mites being 1:1. This is to facilitate the self-reproduction of the predatory mites in the remaining culture bucket 5; Step 4: Place plants for feeding spider mites in the transport box 18 on one side of the culture barrel 5 for feeding spider mites. Some of the spider mites in the culture barrel 5 for feeding spider mites will be transferred to the plants on the transport box 18 adjacent to it, so that the spider mites will be transported into the barrel 1 at the same time when the transport box 18 is subsequently transported into the barrel 1. Step 5: Place only a small amount of nutrients to maintain the feeding of the predatory mites in the transport box 18 on one side of the culture barrel 5 for raising predatory mites. The nutrients can be a mixture of a small amount of corn flour and water. Its role is to ensure that the small amount of predatory mites is not enough to facilitate the subsequent predation of spider mites. Step 6: After 12 hours, the spider mites in the three culture barrels 5 will respectively parasitize the plants close to them, and some spider mites will remain in the culture barrel 5 to continue to reproduce. At this time, the driving rod 3 is rotated in the opposite direction, and the reset spring 20 starts to reset. The button 4 and the driving rod 3 are reset upward under the reset of the reset spring 20. At this time, the harvesting box 11 is lifted up and close to the bottom wall of the barrel body 1. At this time, the connection barrel 7 and the culture barrel 5 close to it are closed, and the connection barrel 7 and the barrel body 1 are connected. As the rotating cylinder 17 rotates to connect the connection barrel 7 and the barrel body 1, the transport box 18 just delivers the plants with spider mites into the barrel body 1, and the predatory mites are also driven into the barrel body 1 at the same time. At this time, there is one predatory mite and three spider mites in the barrel body 1, and the predatory mites will begin to prey on the spider mites; Step 7: The spider mites or predatory mites in the four culture barrels 5 are collectively transported to the barrel body 1 under the drive of the transport box. After all of them are transported into the barrel body 1, the predatory mites begin to prey on the spider mites in the barrel body 1. Step 8: After the predatory mites have preyed on spider mites for a period of time, the predatory mites will gather in the feed area in the harvesting tray 11. Press the button 4 again and slightly turn the driving rod 3 to fix the driving rod 3 and the cross connecting plate 2, so that the harvesting tray 11 is exposed under the barrel 1 for harvesting.

[0029] Implementation method of the present invention: Press the button 4 to separate the harvest box 11 from the bottom of the barrel 1 and expose it. Slightly rotate the driving rod 3 to fix the driving rod 3 and the cross connecting plate 2 to each other. The four connecting barrels 7 outside the side wall of the barrel 1 are now in a closed state. A certain amount of feed can be placed in the harvest box 11. This part of the feed is used to feed the predatory mites. When the predatory mites and spider mites are all placed in the harvest box 11, the predatory mites will prey on the spider mites. After preying on the spider mites, they can continue to eat the feed to avoid food shortage after predation. Several spider mites are respectively placed in three of the culture barrels 5. The number of male and female spider mites put in is 1:1. Its function is to facilitate the spider mites in the three culture barrels 5. For self-reproduction, a number of predatory mites are placed in the remaining culture barrel 5, with the ratio of male to female predatory mites being 1:1. This facilitates the self-reproduction of predatory mites in the remaining culture barrel 5. Plants for feeding spider mites are placed in the transport box 18 on one side of the culture barrel 5 for raising spider mites. Some of the spider mites in the culture barrel 5 for raising spider mites will be transferred to the plants on the transport box 18 close to it, so that the spider mites will be transported into the barrel 1 at the same time when the transport box 18 is subsequently transported into the barrel 1. Only a small amount of nutrients for maintaining the feeding of predatory mites is placed in the transport box 18 on the side of the culture barrel 5 for raising spider mites. The nutrients can be a mixture of a small amount of corn flour and water. , its function is to ensure the small amount of predatory mites' predatory needs, which is convenient for subsequent predation of spider mites. After 12 hours, the spider mites in the three culture barrels 5 will respectively parasitize on the plants close to them, and some spider mites will still stay in the culture barrel 5 to continue breeding. At this time, the driving rod 3 is rotated in the opposite direction, and the reset spring 20 starts to reset. The button 4 and the driving rod 3 are reset upward under the reset of the reset spring 20, and the harvesting box 11 is lifted up and pressed against the bottom wall of the barrel body 1. At this time, the connection barrel 7 and the culture barrel 5 close to it are closed, and the connection barrel 7 and the barrel body 1 are connected. As the rotating cylinder 17 rotates to connect the connection barrel 7 and the barrel body 1, the transport The box 18 just delivers the plants with spider mites into the barrel body 1, and the predatory mites are also driven into the barrel body 1 at the same time. At this time, there will be one predatory mite and three spider mites in the barrel body 1. The predatory mites will start to prey on the spider mites. The spider mites or predatory mites in the four culture barrels 5 will be concentrated and transported to the barrel body 1 under the drive of the transport box. After all are transported into the barrel body 1, the predatory mites begin to prey on the spider mites in the barrel body 1. After the predatory mites prey on the spider mites for a period of time, the predatory mites will concentrate in the feed area of the harvesting tray 11. Press the button again and slightly turn the driving rod 3 to fix the driving rod 3 and the cross connecting plate 2, so that the harvesting tray 11 is exposed under the barrel body 1 for harvesting.

[0030] The present invention can simultaneously raise spider mites and predatory mites. Spider mites can be used as bait for predatory mites without affecting their reproduction, thereby greatly enhancing the raising efficiency of predatory mites. The lifting mechanism of the present invention can lift and lower the harvesting tray. When the harvesting tray is raised, it forms a closed space with the barrel body, which is convenient for predatory mites to prey on spider mites in the closed space. As the harvesting tray is lowered, the four culture barrels become independent closed spaces, which is convenient for raising spider mites and predatory mites separately. The sliding mechanism of the present invention conveniently drives the transport box carrying spider mites or predatory mites to be transported into the barrel body, and as the transport box is transported, the four culture barrels will be sealed by the second rotating mechanism.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
