Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a slow-release device for natural enemy insects used in protected vegetable cultivation. Background Technology

[0002] Vegetable protected areas are special agricultural production environments. By artificially constructing relatively enclosed spaces, suitable conditions such as temperature, humidity, and light are provided for vegetable growth. In vegetable protected areas, there are many common types of pests and diseases. In order to reduce the impact of chemical pesticide residues on the quality and safety of vegetables, some natural enemies of pests are released in the protected areas to achieve biological control.

[0003] Currently, biological control typically involves placing natural enemies of pests in boxes. After bringing the boxes to the protected area, the boxes are opened to allow the insects to fly out. However, a large number of insects fly out at once, and because some insects prefer to live in groups, this can easily lead to aggregation, affecting the control effect. Summary of the Invention

[0004] This invention provides a slow-release device for natural enemy insects used in protected vegetable cultivation. Its release holes can slow down the speed at which insects fly out, allowing them to disperse in the protected area for biological control. This avoids too many insects flying out at once and causing them to gather, thus improving the control effect.

[0005] The first aspect of this utility model provides a slow-release device for natural enemy insects used in protected vegetable cultivation, specifically comprising: a base; a support plate welded to the top of the base, an insect release block fixed to the top of the support plate, four release holes arranged in a ring inside the insect release block, and two symmetrically fixed plates on the top of the insect release block; an insect storage box embedded in the inner side of the insect release block, a spring support plate fixed in the cavity inside the insect storage box, a spring at the bottom of the spring support plate, and a guide rod slidably installed at the bottom center of the insect storage box, with four baffles arranged in a ring on the outer side of the top of the guide rod.

[0006] The baffles are all in close contact with the inner wall of the insect storage box. When the guide rod slides down to the bottom, the baffles will block the round holes on the outer wall of the insect storage box. After the insect storage box is installed, the cylindrical rod in the middle of the top of the support plate will push the guide rod to slide up, and at the same time the baffles will detach from the round holes on the outer wall of the insect storage box.

[0007] The insect release tray has a rectangular groove with an open top on its inner side, and after the insect storage box is installed, its outer wall will be in close contact with the inner wall of the rectangular groove on the inner side of the insect release tray.

[0008] The insect storage box has an inverted trapezoidal protrusion on both the left and right sides. The main body of the card plate is an L-shaped plate, and after the insect storage box is installed, the inverted trapezoidal protrusions on the left and right sides will be stuck under the card plate.

[0009] The release holes are all L-shaped holes, and the outer wall of the insect storage box is also provided with four through holes. After the insect storage box is installed, the through holes on its outer wall will be aligned with the opening at the bottom of the release hole.

[0010] Each of the card plates has an inclined protrusion on one side of its top, and the card plates are all made of elastic plastic.

[0011] The insect storage box has a round tube at the bottom inner center, and the guide rod is in close contact with the inner wall of the round tube. The support plate has a cylindrical rod at the top center, and after the insect storage box is installed, the cylindrical rod at the top center of the support plate will be embedded in the round tube at the bottom inner center of the insect storage box.

[0012] This utility model provides a slow-release device for natural enemy insects used in protected vegetable cultivation, which has the following beneficial effects:

[0013] The insect storage box of this utility model is used to hold the natural enemies of pests that need to be released. Before release, the baffle will automatically close the round hole on the outer wall of the insect storage box to prevent the insects from flying out. During release, it can be installed on the insect release support block. During the installation process, the round hole on the outer wall of the insect storage box will automatically open, and then the natural enemies of pests can fly out slowly through the release hole. Moreover, the release hole can slow down the speed at which the insects fly out, so that the insects are dispersed in the protected area to achieve biological control, avoid the insects from flying out too many at once and gathering together, and improve the control effect.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] This utility model proposes a slow-release device for natural enemy insects used in protected vegetable cultivation, comprising: a base 1; a support plate 2 welded to the top of the base 1, an insect release support block 3 fixed to the top of the support plate 2, the insect release support block 3 having four release holes 4 arranged in a ring inside, and two symmetrically fixed retaining plates 5 on the top of the insect release support block 3. The base 1 supports the support plate 2, the support plate 2 supports the insect release support block 3, and the insect release support block 3 supports the installation of an insect storage box 6. The retaining plates 5 cooperate with the inverted trapezoidal protrusions on the left and right sides of the insect storage box 6 to fix the position of the insect storage box 6. The natural enemies of pests inside the insect storage box 6 will enter the release hole 4 through the round hole on its outer wall and fly outward; an insect storage box 6 is embedded in the inner side of the insect release block 3, and a spring support plate 7 is fixed in the cavity inside the insect storage box 6. A spring is set at the bottom of the spring support plate 7. A guide rod 8 is also slidably installed at the middle of the bottom of the insect storage box 6. Four baffles 9 are arranged in a ring on the outer side of the top of the guide rod 8. The insect storage box 6 is used to hold the natural enemies of pests, the spring support plate 7 is used to support the spring, the guide rod 8 is used to support the baffles 9, and the baffles 9 are used to cover the round hole on the outer wall of the insect storage box 6.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, the baffles 9 are all in close contact with the inner wall of the insect storage box 6. When the guide rod 8 slides down to the bottom, the baffles 9 will block the round holes on the outer wall of the insect storage box 6. After the insect storage box 6 is installed, the cylindrical rod in the middle of the top of the support plate 2 will push the guide rod 8 to slide up. At the same time, the baffles 9 will disengage from the round holes on the outer wall of the insect storage box 6. When the insect storage box 6 is not installed, the spring at the bottom of the spring support plate 7 will push the guide rod 8 and the baffles 9 down to the bottom through the round plate at the top of the guide rod 8. At this time, the baffles 9 can block the round holes on the outer wall of the insect storage box 6, thereby preventing insects from flying out before installation. After the insect storage box 6 is installed, the natural enemies of pests inside can enter the release hole 4 through the round holes on its outer wall and fly out.

[0029] In this embodiment, as Figures 1-5 As shown, the insect release tray 3 has a rectangular groove with an open top on its inner side. After the insect storage box 6 is installed, its outer wall will be in close contact with the inner wall of the rectangular groove on the inner side of the insect release tray 3. When in use, the insect storage box 6 can be carried to the vegetable protection area and installed in the rectangular groove on the inner side of the insect release tray 3. The insect storage box 6 will not shake after installation.

[0030] In this embodiment, as Figures 1-6 As shown, the insect storage box 6 has an inverted trapezoidal protrusion on both the left and right sides. The main body of the card plate 5 is an L-shaped plate. After the insect storage box 6 is installed, the inverted trapezoidal protrusions on the left and right sides will be stuck under the card plate 5. When installing the insect storage box 6, the inclined surface of the bottom of one side of the inverted trapezoidal protrusions on the left and right sides will also contact the top side of the card plate 5 and push the card plate 5 to bend outward. When the insect storage box 6 moves down to the bottom, the inverted trapezoidal protrusions on the left and right sides will be locked by the card plate 5, thereby fixing the position of the insect storage box 6.

[0031] In this embodiment, as Figure 3 , Figure 4 and Figure 6 As shown, the release holes 4 are all L-shaped holes. The outer wall of the insect storage box 6 also has four through holes. After the insect storage box 6 is installed, the through holes on its outer wall will be aligned with the opening at the bottom of the release hole 4. When in use, the natural enemies of pests in the insect storage box 6 can enter the release hole 4 through the through holes on its outer wall. The L-shaped release holes 4 can slow down the speed at which the insects fly out, thus allowing the natural enemies of pests to be released slowly, avoiding the aggregation of too many insects released at one time and affecting the control effect.

[0032] In this embodiment, as Figure 3 and Figure 4As shown, a round tube is located in the middle of the inner side of the bottom of the insect storage box 6. The guide rod 8 is in close contact with the inner wall of the round tube. A cylindrical rod is located in the middle of the top of the support plate 2. After the insect storage box 6 is installed, the cylindrical rod in the middle of the top of the support plate 2 will be embedded in the round tube on the inner side of the bottom of the insect storage box 6. When installing the insect storage box 6, the round rod in the middle of the top of the support plate 2 will first contact the bottom end of the guide rod 8 and push the guide rod 8 and the baffle 9 to slide upward. Therefore, the baffle 9 can be disengaged from the round hole on the outer wall of the insect storage box 6.

[0033] Example 2, based on Example 1, such as Figures 1-6 As shown, each side of the card plate 5 has an inclined protrusion plate on its top, and the card plates 5 are all made of elastic plastic. When the insect storage box 6 needs to be disassembled later, simply pull it outward and bend it through the protrusion plate on the top of one side of the card plate 5. At this time, the card plate 5 can be separated from the inverted trapezoidal protrusion strips on the left and right sides of the insect storage box 6, so that the insect storage box 6 can be disassembled upward.

[0034] The working principle of this embodiment is as follows: During installation, the support plate 2 and the insect release block 3 can be fixed in the vegetable protection area by the base 1. When it is necessary to release the natural enemies of pests, first open the lid of the top of the insect storage box 6, then put the raised or captured insect natural enemies into the insect storage box 6 and tighten the lid. When the insect storage box 6 is not installed, the spring at the bottom of the spring support plate 7 will push the guide rod 8 and the baffle 9 to the bottom through the round plate at the top of the guide rod 8. At this time, the baffle 9 can block the round hole on the outer wall of the insect storage box 6, thereby preventing the insects from flying out before installation. Then, the insect storage box 6 can be carried to the vegetable protection area and installed in the rectangular groove inside the insect release block 3. During installation, simply push the insect storage box 6 downward. During this process, the round rod in the middle of the top of the support plate 2 will first contact the bottom of the guide rod 8 and push the guide rod 8 and the baffle 9 to slide upward. Moreover, the insect storage box 6 can be installed in the vegetable protection area by the spring at the bottom of the base 1. The inclined surfaces at the bottom of the inverted trapezoidal protrusions on both sides of the insect storage box 6 will also contact the top side of the card plate 5 and push the card plate 5 to bend outward. When the insect storage box 6 moves down to the bottom, the inverted trapezoidal protrusions on both sides will be locked by the card plate 5, thereby fixing the position of the insect storage box 6. At this time, the baffle 9 will disengage from the round hole on the outer wall of the insect storage box 6. Therefore, the natural enemies of pests in the insect storage box 6 can enter the release hole 4 through the round hole on its outer wall. The L-shaped release hole 4 can slow down the speed at which the insects fly out, thereby allowing the natural enemies of pests to be released slowly, avoiding the aggregation of too many insects at one time, which would affect the control effect. When the insect storage box 6 needs to be disassembled later, simply pull it outward and bend it by the protrusion on the top side of the card plate 5. At this time, the card plate 5 will disengage from the inverted trapezoidal protrusions on both sides of the insect storage box 6, thereby allowing the insect storage box 6 to be disassembled upward.
