Description

Technical Field

[0001] The present invention relates to the field of pest control equipment, and more particularly to an agricultural pest trapping device. Background Art

[0002] my country is a large agricultural country, and a large number of crops are planted every year. During the planting process, crops are often affected by pests and diseases, especially many crops such as sugarcane are planted densely, and the occurrence of pests and diseases is particularly serious. Sugarcane is a very important sugar crop, and the sucrose produced from it as raw material each year accounts for more than 76% of the world's total sugar production. my country's sugarcane planting areas are mainly distributed in 13 tropical and subtropical provinces and regions, among which the planting areas of Guangxi, Yunnan, Guangdong and Hainan account for 99% of the country's total area. With the large-scale planting of sugarcane, the impact of sugarcane pests is becoming increasingly serious. In order to minimize the impact of sugarcane pests on sugarcane planting, during the sugarcane planting process, attracting lamps are often used to trap pests, using the strong phototaxis of pests to light of a specific wavelength, luring pests to touch the high-voltage power grid with a high frequency vibration, and the pests are electrocuted and fall into the insect box under the power grid. However, the existing attractant lights cannot visually monitor the amount of pests accumulated in the insect receiving box, requiring crop workers to frequently and repeatedly check the amount of pests in the insect receiving box, which invisibly increases the workload. At the same time, when the pests accumulate to a level that exceeds the capacity of the insect receiving box and the crop workers fail to discover and clean them in time, the effect of the attractant lights in killing pests is easily affected.

[0030] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0031] like Figure 1-6 As shown, the present invention provides an agricultural pest trapping device, comprising:

[0032] Mounting cover 7;

[0033] An attracting light 15 is arranged at the bottom of the mounting cover 7;

[0034] A high voltage power grid 16, which is arranged at the bottom of the installation cover 7 and is sleeved outside the attracting light 15;

[0035] An insect receiving box is arranged below the high-voltage power grid 16 and is connected to the mounting cover 7 via a connecting rod 17. The insect receiving box includes a mounting tube 8 and a receiving groove 9 which are coaxially arranged and detachably connected from top to bottom. A horizontal receiving plate 10 is slidably provided in the receiving groove 9, and a supporting spring 11 is provided between the receiving plate 10 and the bottom of the receiving groove 9 to form an elastic support. An extension rod 12 is vertically provided at one end of the receiving plate 10 away from the mounting tube 8. A through hole 20 is penetrated through the bottom of the receiving groove 9. When the weight of the pests on the receiving plate 10 reaches a set amount, under the action of the pests, the receiving plate 10 compresses the supporting spring 11 and drives the extension rod 12 to pass through the through hole 20 and extend out of the receiving groove 9 to form a warning.

[0036] In the above technical solution, the installation cover 7 is a common lampshade, the attracting lamp 15 and the high-voltage power grid 16 are both installed under the installation cover 7, and the high-voltage power grid 16 is sleeved outside the attracting lamp 15, so that the attracting lamp 15 attracts pests, and the high-voltage power grid 16 kills the pests. The selection of the attracting lamp 15 is selected according to the corresponding crops. The structures of the installation cover 7, the attracting lamp 15 and the high-voltage power grid 16 and the connection structures between them are all existing very mature technologies, and no further elaboration is given here;

[0037] The insect receiving box is arranged below the high-voltage power grid 16, and the insect receiving box includes a detachably connected mounting tube 8 and a receiving groove 9. The mounting tube 8 may be in the shape of an inverted mounting cover 7 (but the bottom of the mounting tube 8 is open), that is, the mounting tube 8 and the mounting cover 7 are a pair of lampshades arranged opposite to each other, and the mounting tube 8 is connected to the mounting cover 7 by a connecting rod 17. The number of the connecting rods 17 may be four, and the four vertical connecting rods 17 are evenly spaced and arranged between the mounting cover 7 and the mounting tube 8. The bottom of the mounting tube 8 may be connected to the receiving groove 9 by screw connection, and the inside of the receiving groove 9 is connected to the inside of the mounting tube 8. The receiving groove 9 is connected so that the pests can fall into the receiving groove 9 after being killed by the high-voltage power grid 16; a receiving plate 10 is slidably arranged in the receiving groove 9, and a supporting spring 11 is arranged between the receiving plate 10 and the bottom of the receiving groove 9, that is, one end of the supporting spring 11 is connected to the bottom of the receiving groove 9, and the other end is connected to the bottom of the receiving plate 10, and a protruding rod 12 is arranged at the bottom of the receiving plate 10 (that is, the end away from the mounting tube 8), and a through hole 20 is opened on the bottom of the receiving groove 9 (that is, the bottom of the groove) so that the protruding rod 12 passes through the through hole 20 when the supporting spring 11 is compressed. 0 extends out of the receiving slot 9. When the crop personnel see the extended end of the extension rod 12, they realize that the amount of pests in the collecting slot is about to reach the upper limit, and they can clean the collecting slot to ensure the pest trapping effect. In actual design, the support spring 11 can be a pair, and the pair of support springs 11 are arranged at both ends of the bottom of the receiving plate 10, and one end of the support spring 11 is connected to the bottom of the receiving slot 9, and the other end is connected to the bottom of the receiving plate 10, or the support spring 11 is one, and the support spring 11 can be sleeved on the extension rod 12 and the diameter of the support spring 11 is larger than the perforation The diameter of 20 is so that the support spring 11 can effectively form a support. The support force of the support spring 11 is selected according to the actual situation. When the weight of the pests accumulated on the receiving plate 10 is just equal to the support force of the support spring 11, if pests continue to fall from the receiving plate 10, the receiving plate 10 can be pushed down to the extension rod 12 to extend out of the receiving slot 9. In actual use, when the extension rod 12 just extends out of the receiving slot 9, the receiving slot 9 can be designed so that there is 20-30% of the space for accommodating pests to continue to accommodate pests, so as to give crop personnel time to discover and clean them;

[0038] In this technical solution, during use, the attracting light 15 attracts the pests to the light, the high-voltage power grid 16 kills / stuns the pests, and the pests fall into the receiving slot 9. When the amount of pests on the receiving plate 10 reaches a certain level, the pests push the receiving plate 10 to move the compressed support spring 11 and drive the extending rod 12 to pass through the perforation 20 and extend out of the receiving slot 9. The crop personnel notice that the extending rod 12 extends, that is, they are alerted that the capacity of the insect receiving box is about to reach the upper limit. At this time, the crop personnel can remove the receiving slot 9 and clean the pests.

[0039] The beneficial effect obtained by adopting this technical solution is that, by arranging the installation cover 7, the attracting light 15, the high-voltage power grid 16, the insect receiving box (including the installation tube 8 and the receiving slot 9), the receiving plate 10, the supporting spring 11, the extending rod 12, and the perforation 20, an agricultural pest trapping device is provided, which can visually warn the farmers, making it convenient for the farmers to find and clean them in time, which helps to ensure the effect of the device in attracting and killing pests, and also avoids the need for the farmers to frequently check the amount of pests in the collection slot.

[0040] In another technical solution, a medicine liquid cavity 902 coaxial with the receiving groove 9 is provided inside the side wall of the receiving groove 9, a liquid inlet is provided on the outer wall of the medicine liquid cavity 902, a sealing cover 19 is provided at the liquid inlet, and a scattering hole 904 connected to the interior of the receiving groove 9 is provided on the inner wall of the medicine liquid cavity 902; specifically, an annular medicine liquid cavity 902 is provided inside the side wall of the receiving groove 9, the medicine liquid cavity 902 is coaxial with the receiving groove 9, a liquid inlet is provided on the outer wall of the medicine liquid cavity 902, a sealing cover 19 is provided at the liquid inlet, a scattering hole 904 is provided on the upper part of the inner wall of the medicine liquid cavity 902, and the scattering hole 904 is connected to the interior of the receiving groove 9. The inside of the groove is connected. During actual use, liquid medicine is added into the liquid medicine chamber 902 through the liquid inlet. The liquid medicine in the liquid medicine chamber 902 is selected according to actual conditions, such as attractant liquid medicine, and is sealed by the sealing cover 19. At this time, the attractant liquid medicine is emitted to the outside through the emission hole 904, the inside of the receiving groove 9 and the inside of the mounting tube 8, which can further attract pests to enter the receiving groove 9. In the process of pests entering the receiving groove 9, some pests accidentally touch the high-voltage power grid 16 and are killed, and some pests that are not killed by the high-voltage power grid 16 are also easily trapped in the receiving groove 9 under the attraction of the attractant liquid medicine, so as to minimize the impact of external pests on crops and improve the prevention and control effect.

[0041] In another technical solution, the bottom edge of the mounting tube 8 extends downward to form a cylindrical mounting edge 8021, the outer wall of the receiving slot 9 is detachably connected to the mounting edge 8021, the emitting holes 904 are a pair, the pair of emitting holes 904 are symmetrical about the center of the receiving slot 9, and the emitting holes 904 are arc-shaped holes arranged along the circumference of the inner wall of the liquid medicine chamber 902; it also includes a pair of shielding components arranged in the receiving slot 9, a pair of shielding components corresponds to a pair of emitting holes 904 one by one, each shielding component includes a vertical baffle plate, a support rod 907 arranged at the bottom of the baffle plate, the other end of the support rod away from the baffle plate is connected to the receiving plate 10, a connecting hole 906 is opened in the middle of the baffle plate, the baffle plate located above the connecting hole 906 is the upper baffle plate 903, and the baffle plate located below the connecting hole 906 is the lower baffle plate 905;

[0042] Wherein, an annular step 8022 is coaxially provided inside the mounting tube 8, and the step 8022 is located above the upper baffle plate 903; when the outer wall of the receiving groove 9 is connected to the mounting edge 8021, the step 8022 abuts against the upper baffle plate 903, and the support spring 11 is compressed to cause the connecting hole 906 to communicate with the dispensing hole 904, so that the liquid medicine can be dispensed to the outside; when the amount of pests on the receiving plate 10 reaches a set value, the support spring 11 is compressed and retracted, causing the receiving plate 10 to drop to the upper baffle plate 903 to cover the dispensing hole 904; when the connection between the receiving groove 9 and the mounting edge 8021 is released, and the pests in the receiving groove 9 are dumped, the support spring 11 returns to a natural state, and the lower baffle plate 905 covers the dispensing hole 904;

[0043] In the above technical solution, the structure of the installation cylinder 8 may include a cylinder body 802 located at the lower part and an extension cover 801 located at the upper part of the cylinder body 802. The extension cover 801 is in a trapezoidal truncated cone shape. The small end of the extension cover 801 is connected to the cylinder body 802. The purpose of designing the extension cover 801 is to facilitate connection with the installation cover 7 and receive pests. The structure of the cylinder body 802 can be regarded as a cylindrical through hole opened in the middle of the cylinder. The bottom edge of the cylinder body 802 extends downward to form an installation edge 8021. The installation edge 8021 is cylindrical. The installation edge 8021 and the bottom of the cylinder body 802 form an installation groove, and the notch of the installation groove faces downward.

[0044] The outer wall of the receiving groove 9 is detachably connected to the inner wall of the mounting groove, and the detachable connection can be connected by snap connection, screw connection or by a rebound block; the structure of the receiving groove 9 can be regarded as a cylindrical inner cavity 901 opened inside the middle of the cylinder, the top of the inner cavity 901 is open to communicate with the cylinder 802, and the diameter of the inner cavity 901 is the same as the inner diameter of the cylinder 802, and the inner cavity 901 forms the inner cavity of the receiving groove 9, the receiving plate 10 is slidably arranged on the inner cavity 901, and the support spring 11 is arranged between the receiving plate 10 and the inner bottom wall of the inner cavity 901; the dispensing hole 904 is opened on the common side wall of the liquid medicine cavity 902 and the inner cavity 901 (that is, the inner wall of the liquid medicine cavity 902);

[0045] A pair of shielding components are provided in the receiving slot 9, each shielding component includes a vertical support rod 907 provided on the receiving plate 10, and a baffle provided on the top of the support rod 907, a pair of baffles corresponding to a pair of emission holes 904, a connecting hole 906 is provided in the middle of each baffle, a baffle body located above the connecting hole 906 is an upper baffle 903, and a baffle body located below the connecting hole 906 is a lower baffle 905, and both the upper baffle 903 and the lower baffle 905 are used to shield the emission holes 904;

[0046] The interior of the cylinder 802 is coaxially provided with an annular step 8022, and the step 8022 is arranged above the upper baffle 903, so that when the receiving groove 9 is connected to the mounting cylinder 8, the step 8022 presses the upper baffle 903 to make the support spring 11 in a certain compression state; in actual use, the position of the step 8022, the size of the baffle and the selection of the support spring 11 are designed according to the needs, so that when the device is used normally, the pests pass through the extension cover 801 and the step 8022 (here refers to the inner ring through the step 8022) to enter the receiving groove 9, and when the number of pests in the receiving groove 9 reaches the level that can push the support spring 11 to move, the support spring 11 begins to retract and move, and when the number of pests in the receiving groove 9 reaches a certain level, the support spring 11 moves to the upper baffle 903 to cover the dispensing hole 904. At this time, the accumulation of pests has not reached the lower bottom surface of the dispensing hole 904, so as to avoid a large number of pests from entering through the dispensing hole 904 as much as possible. The medicine liquid chamber 902 is contaminated, thereby reducing the use effect of the medicine liquid chamber 902. At the same time, the extension rod 12 at this time can be designed to have extended out of the receiving slot 9 to form an early warning for the crop personnel, or the extension rod 12 is about to extend out of the receiving slot 9. When the receiving slot 9 further receives pests, the extension rod 12 extends out of the receiving slot; when the crop personnel realize that the receiving slot 9 needs to be cleaned, the receiving slot 9 is removed from the mounting slot. At this time, the upper baffle plate 903 still blocks the dispensing hole 904. In the process of dumping pests, since the pressure of the receiving plate 10 is reduced to no external pressure, the support spring 11 returns to its natural state, and the baffle plate also rebounds to the lower baffle plate 905 to block the dispensing hole 904. At this time, the liquid medicine in the medicine liquid chamber 902 can be avoided from spilling out of the dispensing hole 904 as much as possible (because the pouring process is fast, the time for the connecting hole 906 to be connected with the dispensing hole 904 during the pouring process is very short, and a small part of the liquid medicine may be spilled, and the spilled amount can be ignored);

[0047] In this technical solution, when in use, in the initial state, the receiving slot 9 is separated from the installation slot, and the lower baffle 905 blocks the dispensing hole 904. At this time, after the medicine liquid is added to the medicine liquid chamber 902, the sealing cover 19 is covered, and then the receiving slot 9 is connected to the installation slot. When the connection is completed, since the top of the upper baffle 903 contacts the bottom of the step 8022, the connecting hole 906 is connected with the dispensing hole 904. The medicine liquid in the medicine liquid chamber 902 enters the inner cavity 901 through the dispensing hole 904 and the connecting hole 906, and is further dissipated to the outside through the gap between the high-voltage power grid 16 and the insect receiving box to attract pests. Under the attraction of the attractant liquid, some of the pests accidentally touch the high-voltage power grid 16 and are killed, and some of the pests that are not accidentally touched are discharged from the gap between the high-voltage power grid 16 and the insect receiving box or from the high-voltage power grid 1 6 enters the insect receiving box (receiving slot 9) through the pores of the attractant liquid. Under the attraction of the attractant liquid, the pests are trapped in the collecting slot 9 to further improve the trapping effect of the pests. The use of liquid attractant liquid not only provides a wide variety of attractant liquids to choose from, but also has a good drug distribution effect, which helps to quickly attract the pests. When it is necessary to dump the pests in the collecting slot 9, the receiving slot 9 is removed from the mounting slot and the pests are poured out. After the pests are poured out, the support spring 11 returns to its natural state. At this time, the lower baffle 905 blocks the distribution hole 904 under the action of the rebound force, which can minimize the outflow of the liquid from the distribution hole 904 and cause waste of the liquid. At the same time, the distribution hole 904 is designed as a pair of arc-shaped holes, which is conducive to the rapid distribution of the attractant liquid and can attract pests faster and better.

[0048] In another technical solution, it also includes an electric heating rod 18, and the heating end of the electric heating rod 18 is sealed and extends into the liquid chamber 902; specifically, the electric heating rod 18 is an existing structure, such as the electric heating rod 18 of the existing electric mosquito repellent liquid; when in use, the electric heating rod 18 heats the attractant liquid, which can accelerate the rapid dissipation of the liquid and further improve the trapping and killing effects.

[0049] In another technical solution, an external thread is provided on the outer wall of the receiving groove 9, and an internal thread matched with the external thread is provided on the inner wall of the mounting edge 8021, and the top of the baffle is a smooth convex arc surface; specifically, the receiving groove 9 is screwed with the mounting groove through the external thread and the internal thread. When in use, the receiving groove 9 is screwed into the mounting groove, and when it is screwed in to the top of the upper baffle 903 and contacts the bottom of the step 8022 (the top of the upper baffle 903 can be designed to be a convex arc shape to reduce friction damage), the baffle compresses the support spring 11 under the action of the screw-in force and the step 8022, so that the dispensing hole 904 is connected with the connecting hole 906. At this time, the liquid medicine in the liquid medicine chamber 902 can lure pests into the receiving groove 9 after dispensing, thereby further improving the prevention and control effect.

[0050] In another technical solution, a warning film is provided on the end of the extension rod 12 away from the receiving plate 10; the beneficial effect obtained by adopting this technical solution is that by providing a warning film, it is easy to attract the attention of crop personnel, and they can quickly discover that the amount of pests in the receiving groove 9 is about to reach the limit.

[0051] In another technical solution, the warning film includes a reflective film 13 and a fluorescent film 14 which are sequentially arranged along the circumference of the extending rod 12; the beneficial effect obtained by adopting this technical solution is that the reflective film 13 and the fluorescent film 14 are adopted, the reflective film 13 is easy to attract people's attention during the day, and the fluorescent film 14 will emit fluorescence at night, which also attracts people's attention, warning the crop personnel that the amount of pests in the collection trough 9 is about to reach the limit.

[0052] In another technical solution, it also includes a base 1, a moving wheel 21 is provided at the bottom of the base 1, a column 2 is provided on the base 1, a mounting block 3 is provided on the column 2, a support plate 4 is provided on the side wall of the mounting block 3, and the mounting cover 7 is provided on the support plate 4; specifically, the moving wheel 21 can select the existing moving wheel 21 with a brake part, the support plate 4 is located on one side of the column 2, a vertical rod 5 is provided at the bottom of the support plate 4, and the top of the mounting cover 7 is connected to the bottom of the vertical rod 5 so as to be connected to the support plate 4 through the vertical rod 5; adopting this technical solution, the beneficial effect obtained is that a structure for installing an attractant lamp 15, a high-voltage power grid 16 and an insect receiving box is provided, which is convenient for moving the pest trapping device to a suitable position for installation, and has strong practicality.

[0053] In another technical solution, a solar panel 6 is provided on the top of the column 2, and the solar panel 6 is connected to the attractant light 15. By adopting this technical solution, the beneficial effect obtained is that by setting up the solar panel 6, the solar panel 6 absorbs light energy and converts it into electrical energy to power the attractant light 15, thereby achieving environmental protection and energy-saving effects.

[0054] In another technical solution, the height of the mounting block 3 is adjustable. Specifically, the mounting block 3 can be designed as a structure similar to a clamp. By adjusting the height position of the mounting block 3 on the column 2 and then locking the clamp, the height of the mounting block 3 can be adjusted. Alternatively, the height of the mounting block 3 can be adjusted in the following manner: the column 2 is provided with a plurality of fixing holes arranged along its axial direction, a sliding hole is penetrated in the middle of the mounting block 3, and the column 2 passes through the sliding hole so that the mounting block 3 is slidably connected to the column 2. Mounting holes are also penetrated on the two side walls of the mounting block 3. When the mounting hole is coaxial with one of the fixing holes, a pin is used to pass through one of the mounting holes, the fixing hole, and the other mounting hole, so that the mounting block 3 can be connected and fixed to the column 2. By connecting the mounting block 3 to the fixing holes at different heights, the height of the mounting block 3 can be adjusted. The technical solution has the beneficial effect that by adjusting the height of the mounting block 3, the position of the attracting light 15 can be adaptively adjusted according to actual conditions (such as the height of the crop or installing the attracting light 15 at a position convenient for crop personnel to operate), which is more practical.
