Description

Technical Field

[0001] This utility model relates to the field of aphid trapping technology, specifically to a crop aphid trapping device. Background Technology

[0002] Aphids are one of the major pests of crops. They congregate on the back of leaves, tender stems, growing points and flowers to suck sap and cause damage, resulting in curled branches and leaves, stunted growth, and even the spread of viral diseases, which seriously affect crop yield and quality. Therefore, the control of aphids is particularly important.

[0003] A search revealed a utility model patent with Chinese patent publication number CN209314659U, which discloses an agricultural aphid trapping device. The device comprises an attractant mounting frame, a collection tube, and a trapping tube. The outer surface of the collection tube has an external thread, and the inner surface of the trapping tube has an internal thread. The collection tube is screwed onto the bottom of the trapping tube via the threaded structure. The trapping tube has a set of trapping channels arranged in a ring on its surface, and these channels are integral with the trapping tube. The trapping channels have a flared outer inlet and a tapering inner inlet, with the tapering structure located inside the trapping tube.

[0004] The aforementioned device uses a hanging ring to attach to crops to trap aphids. However, for fruit trees, aphids often gather on tender branches, which have low support capacity. The device can only be attached to older branches, which is too far from the tender branches and does not improve the trapping rate. Furthermore, for grains and legumes, the support capacity is even lower, so the device is not suitable and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a crop aphid trapping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crop aphid trapping device, comprising a trapping barrel, wherein a plurality of equally spaced funnel-shaped inlets are provided on the outer circumference of the trapping barrel, a support assembly is fixedly connected to the bottom of the trapping barrel, the support assembly includes a connecting frame fixedly connected to the outer wall of the bottom of the trapping barrel, a vertically arranged guide rod is slidably connected to the end of the connecting frame away from the trapping barrel, a plurality of equally spaced limiting holes are provided inside the guide rod, a pin is slidably connected inside the connecting frame, the pin is slidably connected inside one of the limiting holes, a connecting structure is fixedly connected to the bottom end of the guide rod, a plurality of receiving assemblies are fixedly connected inside each of the plurality of inlets, an installation chamber is fixedly connected to the top outer wall of the trapping barrel, and an attracting structure is fixedly connected inside the installation chamber.

[0007] This device allows the trapping bucket to be positioned close to the tender branches of crops without being affected by the type of crop, thus ensuring aphid trapping rates. It can also adapt to aphid trapping on crops of different heights. If the crop height is less than the guide rod height, place the guide rod on the ground first, then step on the clamping plate and apply pressure to insert the ground nail at its bottom, thus fixing the guide rod in place. If the crop is a fruit tree, wrap two clamping plates around the outside of the branches, then flip the screw inside one clamping plate. When the screw passes through the groove of the other clamping plate, twist the nut to press the other clamping plate, thus clamping and fixing it in place. Then, push the connecting frame to slide along the guide rod, bringing the trapping bucket at the top of the connecting frame closer to the height where aphids tend to gather. Then, push the pin along the connecting frame to move it closer to the guide rod, and finally select the nearest limiting hole and insert it. The positions of the connecting frame and the trapping bucket will then be fixed, improving the adaptability of the device.

[0008] As a further preferred embodiment of this technical solution, the connection structure includes two mounting seats fixedly connected to the outer wall of one side of the guide rod. Each of the two mounting seats is rotatably connected to a vertically arranged clamping plate, and the two clamping plates are symmetrically arranged. Each clamping plate has two mounting grooves at the end away from the guide rod. A screw is rotatably connected inside each of the two mounting grooves of one of the clamping plates. Two vertically arranged ground nails are fixedly connected to the bottom outer wall of each of the two clamping plates.

[0009] As a further preferred embodiment of this technical solution, the guiding assembly includes a guiding rope fixedly connected to the inner wall of the inlet circumference, a movable ring slidably connected to the outside of the guiding rope, a Torx handle screw threadedly connected inside the movable ring, one bottom end of the Torx handle screw contacting the guiding rope, and a hook fixedly connected to the bottom outer wall of the movable ring.

[0010] Pick up the movable end of the guide rope, then push the moving ring along the guide rope so that the hook at its bottom is close to the tender branch of the crop. Then twist the plum blossom handle screw inside the moving ring. The plum blossom handle screw, together with the moving ring, can tightly squeeze the guide rope. Under the action of static friction, the position of the moving ring and the hook will also be fixed. Finally, hang the hook on the tender branch of the crop. The guide rope will form a "channel" between the trap and the tender branch, making it easier for aphids to approach the trap and further improving the trapping rate.

[0011] As a further preferred embodiment of this technical solution, the outer circumference of the trapping barrel is fixedly connected with a number of climbing ropes that are distributed at equal intervals.

[0012] As a further preferred embodiment of this technical solution, the inducing structure includes a collar fixedly connected to the outer wall of the bottom of the installation chamber, a paper tube fixedly sleeved on the outside of the collar, a lamp holder fixedly connected to the middle position of the installation chamber, and a lamp rod fixedly installed at the interface of the lamp holder.

[0013] As a further preferred embodiment of this technical solution, a photovoltaic panel is fixedly connected to the outer wall of the top of the installation chamber, and a battery pack connected in series is fixedly connected to the inner wall of the bottom of the installation chamber. The battery pack is electrically connected to the photovoltaic panel and the lamp holder through wires.

[0014] As a further preferred embodiment of this technical solution, a slot is provided at the bottom of the outer circumference of the trapping barrel, and a drawer is slidably connected inside the slot. The top edge of the inner circumference of the drawer is rounded.

[0015] This utility model provides a device for trapping aphids on crops, which has the following beneficial effects: (1) By setting up a support component, this utility model can make the trapping bucket close to the tender branches of crops without being affected by the type of crops, which is conducive to ensuring the aphid trapping rate and can also adapt to the aphid trapping work of crops of different heights. If the height of the crops is less than the height of the guide rod, the guide rod is placed on the ground first, and then the foot clamp plate is stepped on and pressure is applied so that the ground nail at the bottom is inserted into the ground, thus fixing the position of the guide rod. If the crops are fruit trees, the two clamp plates are wrapped around the outside of the branches, and then the screw inside one of the clamp plates is flipped. When the screw passes through the groove of the other clamp plate, the nut is twisted to squeeze the other clamp plate, thus completing the clamping fixation. Then the connecting frame is pushed to slide along the guide rod so that the trapping bucket at the top of the connecting frame is close to the height where aphids are easy to gather. Then the pin is pushed to move along the connecting frame to the guide rod. Finally, the nearest limiting hole is selected and inserted into it, and the positions of the connecting frame and the trapping bucket will be fixed, which is conducive to improving the adaptability of the device.

[0016] (2) By setting up a receiving component, the movable end of the receiving rope is picked up, and then the moving ring is pushed to slide along the receiving rope so that the hook at the bottom is close to the tender branches of the crop. Then the plum blossom handle screw inside the moving ring is twisted. The plum blossom handle screw and the moving ring can tightly squeeze the receiving rope. Under the action of static friction, the position of the moving ring and the hook will also be fixed. Finally, the hook is hung on the tender branches of the crop. The receiving rope can form a "channel" between the trap and the tender branches, making it easier for aphids to approach the trap and further improving the trapping rate.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 1 As shown in Figure 4, in this embodiment, a crop aphid trapping device includes a trapping barrel 1. The outer circumference of the trapping barrel 1 has several funnel-shaped inlets distributed at equal intervals. A support assembly 8 is fixedly connected to the bottom of the trapping barrel 1. The support assembly 8 includes a connecting frame 801 fixedly connected to the outer bottom wall of the trapping barrel 1. A vertically arranged guide rod 802 is slidably connected to the end of the connecting frame 801 away from the trapping barrel 1. Several equidistant limiting holes 803 are opened inside the guide rod 802. A pin 804 is slidably connected inside the connecting frame 801. The pin 804 is slidably connected inside one of the limiting holes 803. A connecting structure is fixedly connected to the bottom end of the guide rod 802. Several receiving assemblies 7 are fixedly connected inside each of the several inlets. An installation chamber 2 is fixedly connected to the top outer wall of the trapping barrel 1. An attracting structure is fixedly connected inside the installation chamber 2.

[0020] The connection structure includes two mounting seats fixedly connected to the outer wall of one side of the guide rod 802. Each of the two mounting seats is rotatably connected to a vertically arranged clamp plate 805, and the two clamp plates 805 are symmetrically arranged. Each clamp plate 805 has two mounting grooves at the end away from the guide rod 802. A screw is rotatably connected inside each of the two mounting grooves of one clamp plate 805. Two vertically arranged ground nails 806 are fixedly connected to the bottom outer wall of each clamp plate 805.

[0021] If the height of the crop is less than the height of the guide rod 802, place the guide rod 802 on the ground first, then step on the clamp plate 805 and apply pressure to insert the ground nail 806 at its bottom into the ground, thus fixing the position of the guide rod 802. If the crop is a fruit tree, wrap the two clamp plates 805 around the outside of the branches, then flip the screw inside one of the clamp plates 805. When the screw passes through the groove of the other clamp plate 805, twist the nut to squeeze the other clamp plate 805, thus completing the clamping fixation. Then push the connecting frame 801 to slide along the guide rod 802, so that the trapping bucket 1 at the top of the connecting frame 801 is close to the height where aphids are likely to gather. Then push the pin 804 to move it along the connecting frame 801 close to the guide rod 802. Finally, select the nearest limiting hole 803 and insert it into it. The positions of the connecting frame 801 and the trapping bucket 1 will be fixed, which helps to improve the adaptability of the device.

[0022] like Figure 2 and Figure 3 As shown, the guide assembly 7 includes a guide rope 701 fixedly connected to the inner wall of the inlet circumference. A movable ring 702 is slidably connected to the outside of the guide rope 701. A Torx handle screw 704 is threadedly connected inside the movable ring 702. One end of the Torx handle screw 704 contacts the guide rope 701. A hook 703 is fixedly connected to the bottom outer wall of the movable ring 702.

[0023] Pick up the movable end of the guide rope 701, then push the moving ring 702 to slide along the guide rope 701, so that the hook 703 at its bottom is close to the tender branch of the crop. Then twist the plum blossom handle screw 704 inside the moving ring 702. The plum blossom handle screw 704, together with the moving ring 702, can tightly squeeze the guide rope 701. Under the action of static friction, the positions of the moving ring 702 and the hook 703 will also be fixed. Finally, hang the hook 703 on the tender branch of the crop. The guide rope 701 can form a "channel" between the trap 1 and the tender branch, making it easier for aphids to approach the trap 1, which can further improve the trapping rate.

[0024] The outer circumference of the trapping bucket 1 is fixedly connected with several climbing ropes 705 that are evenly distributed.

[0025] The climbing rope 705 fixed to the outside of the trapping bucket 1 can provide aphids with a point of leverage to attach to the branches of the device, thereby avoiding trapping failure due to the lack of a point of leverage on the surface of the trapping bucket 1.

[0026] like Figure 1 As shown in Figure 2, the attraction structure includes a collar fixedly connected to the bottom outer wall of the installation chamber 2, a paper tube 5 fixedly fitted on the outside of the collar, a lamp holder 3 fixedly connected in the middle of the installation chamber 2, a lamp stick fixedly installed at the interface of the lamp holder 3, and the trapping barrel 1 is made of transparent PVC material so that the reflection of the paper tube 5 can be emitted normally, thereby attracting aphids better.

[0027] like Figure 1 As shown in Figure 2, a photovoltaic panel 4 is fixedly connected to the outer wall of the top of the installation chamber 2, and a battery pack connected in series is fixedly connected to the inner wall of the bottom of the installation chamber 2. The battery pack is electrically connected to the photovoltaic panel 4 and the lamp holder 3 through wires. The photovoltaic panel 4 can convert light energy into electrical energy and store it in the battery pack. The battery pack can then power the lamp holder 3, thereby making the lamp light up and enabling the device to work at night.

[0028] like Figure 1 As shown in Figure 2, a slot is provided at the bottom of the outer circumference of the trap 1, and a drawer 6 is slidably connected inside the slot. The top edge of the inner circumference of the drawer 6 is rounded to prevent aphids from being trapped on the top wall. Aphids that enter the trap 1 through the entrance will slide down and be caught by the drawer 6 at the bottom. The inner wall of the drawer 6 is vertical and has a smooth surface, which can effectively prevent aphids from climbing up and escaping.

[0029] This utility model provides a device for trapping aphids on crops, the specific working principle of which is as follows: When the device is in operation, if the height of the crop is less than the height of the guide rod 802, place the guide rod 802 on the ground first, then step on the clamp plate 805 and apply pressure to insert the ground nail 806 at its bottom into the ground, thus fixing the position of the guide rod 802. If the crop is a fruit tree, wrap the two clamp plates 805 around the outside of the branches, then flip the screw inside one of the clamp plates 805. When the screw passes through the groove of the other clamp plate 805, twist the nut to squeeze the other clamp plate 805, thus completing the clamping and fixing. Then push the connecting frame 801 to slide along the guide rod 802, so that the trapping bucket 1 at the top of the connecting frame 801 is close to the height where aphids are likely to gather. Then push the pin 804 to move it along the connecting frame 801 close to the guide rod 802. Finally, select the nearest limiting hole 803 and insert it into it. The positions of the connecting frame 801 and the trapping bucket 1 will be fixed, which helps to improve the adaptability of the device.

[0030] Pick up the movable end of the guide rope 701, then push the moving ring 702 to slide along the guide rope 701, so that the hook 703 at its bottom is close to the tender branch of the crop. Then twist the plum blossom handle screw 704 inside the moving ring 702. The plum blossom handle screw 704, together with the moving ring 702, can tightly squeeze the guide rope 701. Under the action of static friction, the positions of the moving ring 702 and the hook 703 will also be fixed. Finally, hang the hook 703 on the tender branch of the crop. The guide rope 701 can form a "channel" between the trapping bucket 1 and the tender branch, making it easier for aphids to approach the trapping bucket 1, which can further improve the trapping rate. The climbing rope 705 fixed to the outside of the trapping bucket 1 can provide aphids with a point of leverage for attaching to the branch of the device, thereby avoiding the trapping failure due to the lack of a point of leverage on the surface of the trapping bucket 1.
