Description

Technical Field

[0001] This utility model belongs to the field of orchard pest technology, specifically relating to an orchard pest trapping device. Background Technology

[0002] An orchard pest trapping device is a tool used to control orchard pests. It reduces the damage to crops by attracting and capturing pests. It can also send the collected orchard pests to the laboratory for testing. Therefore, an orchard pest trapping device is needed.

[0003] Existing orchard pest trapping devices, such as the forestry pest trapping device disclosed in patent number CN203675927U, consist of a long vertical pipe and two short vertical pipes fixedly connected to an upper support plate and a lower support plate through holes at the three corners of the upper and lower support plates. Three bait boxes are fixed to the upper and lower supports of the upper support plate through through holes in the bait boxes. A power supply box is fixed to the lower support plate, containing a high-voltage pulse generator and a power supply. A lamp plate is connected to the threaded holes at the upper ends of the long and short vertical pipes through bolts and washers. An insect-attracting lamp is fixed below the lamp plate. A lamp frame is fixed around the lamp plate. A high-voltage grid is fixed to the lamp frame. Threaded column feet are connected to the threaded holes at the lower ends of the long and short vertical pipes.

[0004] Existing orchard pest trapping devices cannot generate physical suction to past pests, and their complex structure makes them unsuitable for single-person handheld use. Therefore, this utility model proposes an orchard pest trapping device. Utility Model Content

[0005] The purpose of this invention is to provide an orchard pest-catching device that facilitates the capture and collection of insects.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A pest-catching device for orchards includes a centrifuge chamber, one end of which is connected to a tapered acceleration tube, one end of which is connected to a wide-mouth suction head, and the other end of which is detachably connected to a turbine fan. A conical funnel is connected through the lower end of the centrifuge chamber, and a collection tube is detachably attached to the conical funnel.

[0008] The centrifuge chamber has a cross-shaped structure at its other end, with an installation shaft connected to the center of the cross-shaped structure. Three support rods are mounted on the installation shaft, and the projections of the three support rods on the vertical section are arranged in a circular array at equal angles around the installation shaft. The projections of the three support rods on the horizontal plane are spaced equally between adjacent ones, and guide vanes are mounted on the support rods.

[0009] Preferably, the turbine fan includes a fan housing detachably connected to the centrifugal chamber, a motor is installed inside the fan housing, the output end of the motor is connected to a drive shaft, and fan blades are installed on the drive shaft.

[0010] Preferably, the fan housing is connected to the centrifuge chamber by bolts, and a filter screen is provided at the rear end of the fan housing.

[0011] Preferably, the guide vane is inclined at 45°, and the longitudinal section sidewall of the tapered acceleration tube is inclined at 15°.

[0012] Preferably, the conical funnel and the centrifuge chamber are integrally cast, and the lower outer wall of the conical funnel is provided with two rubber protrusions, which are tightly fitted with the grooves on the inner wall of the collection tube.

[0013] Preferably, the lower end of the fan housing is provided with a handle, the handle is provided with a button switch, and the handle contains a battery.

[0014] Preferably, the lower end of the fan housing is provided with a handle, the handle is provided with a button switch, and the handle contains a battery.

[0015] The technical effects achieved by this utility model are as follows:

[0016] 1. Improved capture efficiency and success rate. The combination of centrifugal force, a baffle chamber, and a turbine fan enhances capture efficiency. Furthermore, the tapered acceleration tube design strengthens suction, resulting in a higher capture success rate. This is especially effective for capturing agile and difficult-to-catch insects with greater precision.

[0017] 2. The user holds the handle, aims the wide-mouth suction head at the insect, presses the button switch, starts the motor, and the turbine fan starts working. The motor drives the drive shaft to rotate, and the drive shaft drives the fan blades to rotate. The turbine fan works to create negative pressure suction, which sucks the pests into the centrifuge chamber from the wide-mouth suction head and the tapered acceleration tube. This makes the device flexible and convenient to operate, and one person can operate it.

[0018] 3. The device has three guide vanes, all tilted clockwise at 45 degrees. When airflow enters, it rotates along the tilt of the vanes, carrying the insects through centrifugal motion. The insects are gradually thrown against the inner wall of the centrifuge chamber. Some insects may be directly thrown into the lower part of the centrifuge chamber wall, passing through a conical funnel into the collection tube. This keeps the inner wall of the centrifuge chamber lubricated. When the guide vanes stop rotating and centrifugation ceases, the insects slide to the lower part of the centrifuge chamber under their own gravity, passing through the conical funnel into the collection tube. The collection tube is then removed to retrieve the captured insects for subsequent testing experiments. This device facilitates collection and preservation: insects are collected using centrifuge tubes, and preservation solutions such as alcohol can be added to the tubes for convenient observation, research, and preservation. This device is suitable for supplementing various small insects. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-4As shown, an orchard pest trapping device includes a centrifuge chamber 1, a tapered acceleration tube 2 connected to one end of the centrifuge chamber 1, a wide-mouth suction head 3 connected to one end of the tapered acceleration tube 2, a turbine fan 4 detachably connected to the other end of the centrifuge chamber 1, a conical funnel 5 connected through the lower end of the centrifuge chamber 1, and a collection tube 6 detachably connected to the conical funnel 5.

[0027] A cross 7 is provided inside the other end of the centrifuge chamber 1. A mounting shaft 8 is connected to the center of the cross 7. Three support rods 9 are provided on the mounting shaft 8. The projections of the three support rods 9 on the vertical section are distributed in a circular array at equal angles around the mounting shaft 8. The adjacent spacing between the projections of the three support rods 9 on the horizontal plane is equal. A guide vane 10 is installed on the support rod 9. Preferably, the guide vane 10 is inclined at 45°, and the longitudinal section sidewall of the tapered acceleration tube 2 is inclined at 15°.

[0028] like Figures 1-4 As shown, in this invention, the turbine fan 4 starts working, creating negative pressure suction to draw pests into the centrifuge chamber 1 from the wide-mouth suction head 3 and the tapering acceleration tube 2. The tapering acceleration tube 2 has a "wide front, narrow back" structure. According to Bernoulli's principle, when the cross-sectional area of ​​the pipe decreases, the fluid velocity increases while the pressure decreases. If the diameters of the front and rear ends are the same, the flow velocity cannot be increased, resulting in insufficient suction and reduced capture efficiency. Furthermore, if the pipe is straight without a tapering structure, greater suction may be required to achieve the same effect, but this would increase energy consumption or require a more powerful fan, affecting the convenience of the device and the lifespan of the battery 14.

[0029] Preferably, the turbine fan 4 includes a fan housing 402 detachably connected to the centrifugal chamber 1, a motor 403 is installed inside the fan housing 402, the output end of the motor 403 is connected to the drive shaft 401, and fan blades 404 are installed on the drive shaft 401.

[0030] When the turbine fan 4 is started, the motor 403 drives the drive shaft 401 to rotate, which in turn drives the fan blades 404 to rotate, creating a turbine airflow. Under the action of the guide vanes 10, the airflow moves along the direction of the guide vanes 10, ultimately causing the insects to undergo centrifugal motion. The centrifugal separation chamber design within the centrifugal chamber 1, facilitated by the guide vanes 10, separates the inhaled insects from the airflow. This ensures that some insects pass directly through the conical funnel 5 into the collection tube 6, while the rest are centrifuged to the inner wall of the centrifugal chamber 1 and then slide down into the collection tube 6. Without the centrifugal separation chamber, insects might be blown directly into the turbine fan 4, making it impossible to effectively collect them into the collection tube 6.

[0031] Preferably, the fan housing 402 is connected to the centrifuge chamber 1 by bolts, and a filter screen 405 is provided at the rear end of the fan housing 402. The filter screen 405 mainly prevents impurities from entering the turbine fan 4.

[0032] Preferably, the conical funnel 5 and the centrifuge chamber 1 are integrally cast. Two rubber protrusions 11 are provided on the lower outer wall of the conical funnel 5. These rubber protrusions 11 fit tightly into the grooves on the inner wall of the collecting tube 6. In this invention, the rubber protrusions 11 are fixedly bonded to the lower outer arm of the conical funnel 5. The two rubber protrusions 11 only fit into the grooves on the inner wall of the collecting tube 6, achieving stable installation of the collecting tube 6. As the collecting tube 6 is inserted or removed, the two rubber protrusions 11 will not fall off. Ultimately, this allows for easy removal or installation of the collecting tube 6, while ensuring its secure installation.

[0033] Preferably, a handle 12 is provided at the lower end of the fan housing 402, a button switch 13 is provided on the handle 12, and a battery 14 is provided inside the handle 12. By holding the handle 12 and pressing the button switch 13, the motor 403 is started and the turbine fan 4 begins to work.

[0034] like Figures 1-4 As shown, the working principle of this utility model is as follows: the user holds the handle 12, aligns the wide mouth suction head 3 with the insect, presses the button switch 13, starts the motor 403, the turbine fan 4 starts to work, the motor 403 drives the drive shaft 401 to rotate, the drive shaft 401 drives the fan blades 404 to rotate, the turbine fan 4 works, forming a negative pressure suction, so that the pests are sucked into the centrifuge chamber 1 from the wide mouth suction head 3 and the tapered acceleration tube 2;

[0035] There are three guide vanes 10, all tilted at 45 degrees clockwise. When the airflow comes in, it will start to rotate along the tilt direction of the guide vanes 10. The airflow carries the insects together in centrifugal motion and is gradually thrown towards the inner wall of the centrifuge chamber 1. The insects may be directly thrown into the lower end of the inner wall of the centrifuge chamber 1, and enter the collection tube 6 through the conical funnel 5. Keep the inner wall of the centrifuge chamber 1 lubricated. When the guide vanes 10 stop rotating and no longer generate centrifugation, the insects slide to the lower end of the centrifuge chamber 1 under their own gravity, and enter the collection tube 6 through the conical funnel 5. The collection tube 6 is removed to take out the captured insects for subsequent testing experiments.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
