Description

Technical Field

[0001] This invention relates to the field of spore traps, and more specifically to a field spore trap. Background Technology

[0002] The spore trap is specifically designed to collect airborne pathogen spores and pollen particles. It is primarily used to detect the abundance and spread dynamics of pathogen spores, providing reliable data for predicting and preventing disease outbreaks and transmission. The spore trap can accurately detect and capture airborne pathogen spores, which are then observed under a microscope on a slide. This convenient and easy method is widely used for spore detection and counting of fungi and other microorganisms, as well as for the effective control of plant diseases. It is an essential piece of equipment for crop disease monitoring that agricultural plant protection departments should be equipped with.

[0003] For example, utility model patent application number 201820778250.1 discloses a spore trapping device with a multi-position spore observation apparatus. It includes a slide chamber, a spore trap, a culture chamber, a spore observation component, and a slide translation mechanism. The slide chamber has two integrally formed slide storage cavities, each containing multiple layers of slides. Each slide has at least three grooves along its length. The slide translation mechanism pushes out one slide at a time from each of the two slide storage cavities. Driven by the slide translation mechanism, the two slides move sequentially to below the spore trap, the culture chamber, and the spore observation component. This spore trapping device with a multi-position spore observation apparatus has the advantages of scientific design, collecting more spore samples per unit time, more accurate determination and prediction of pest and disease occurrence, high work efficiency, and time and labor saving.

[0004] The aforementioned spore traps are mostly large instruments that are not easy to move around and cannot be moved flexibly in the field. Moreover, these devices are generally expensive, and most growers cannot afford their high costs, which leads to an inability to effectively control plant diseases.

[0013] As a preferred embodiment of the present invention, a ventilation channel is formed between the outer wall of the connecting cylinder and the inner wall of the communicating shell, and a plurality of ventilation holes arranged in a ring array near the outer edge of the fixed plate for communicating with the ventilation channel are provided.

[0014] As a preferred embodiment of the present invention, a brushless fan is provided below the electric motor. The brushless fan is fixed to the bottom center of the fixed plate located at the lower part by bolts. The brushless fan is used to blow air containing spores toward the glass slide. A main control board for control and a lithium battery for power supply are respectively provided on both sides of the electric motor. The main control board is electrically connected to the brushless fan, the electric motor and the LED light strip through a control circuit. The lithium battery is electrically connected to the main control board, the brushless fan, the electric motor and the LED light strip through wires.

[0015] As a preferred embodiment of the present invention, the bracket includes an upper contact block and a lower connecting plate that is slidably connected to the inner wall of the mounting box.

[0022] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0023] 1. An electric motor can control the rotation of the lead screw, which causes the nut slide to move the moving plate upward. The moving plate then moves the adjusting rod upward to expose the strip ventilation hole. At the same time, the elastic component causes the bracket to move the filter strip upward, which covers the strip ventilation hole. Combined with a brushless fan, the spore collection can be completed. Compared with the large spore traps in the prior art, this invention is small in size, low in cost, can be fixed in any suitable location in the field, is easy to carry, and has greater flexibility.

[0024] 2. During the collection process, filter strips are used to filter the air drawn into the spore trap by the brushless fan, preventing large particles from entering the trap. In addition, the size of the strip ventilation holes can be adjusted by changing the position of the adjusting rod, thereby changing the air intake. When not in use, the adjusting rod can block the strip ventilation holes to prevent dust. When cleaning is required, the moving disc drives the brush roller to move up and down to clean the walls of the strip ventilation holes. Since the brush roller adopts a rotating connection, it will rotate due to friction during the up and down movement, which can further improve the cleaning effect and achieve automatic cleaning, making it more convenient to use.

[0025] 3. When the support rod moves down, it causes the bracket to move down, which in turn compresses the spring, which acts as a buffer. At the same time, the limiting post limits the bracket. When the support rod moves up, the spring force causes the bracket to move up, which in turn moves the filter strip up to cover the exposed strip ventilation hole. When the brushless fan collects spores, the filter strip filters the air drawn into the spore trap through the brushless fan, preventing large particles of impurities from entering the spore trap.

[0026] 4. Activate the LED light strip via the main control board to make the LED light strip light up, so that the operator can easily find the spore trap at night, which is conducive to the operator's recovery of the glass slide. Attached Figure Description

[0044] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] This invention provides, for example Figure 1-8 The field spore trap shown includes a ventilated shell 1, which is a cylindrical structure with an opening at the lower end. The outer wall of the ventilated shell 1 has strip-shaped ventilation holes 11 arranged in a ring array, and the top of the strip-shaped ventilation holes 11 is connected to a guide groove 12.

[0046] The connecting shell 2 is located at the bottom of the ventilation shell 1. The connecting shell 2 is a cylindrical structure with openings at both ends. The interior of the connecting shell 2 is provided with a control unit 7. The outer wall of the connecting shell 2 is provided with a number of filter units 6 arranged in a circular array along the circumference. Each filter unit 6 includes a mounting box 61 fixed to the outer wall of the connecting shell 2. The mounting box 61 is provided with a filter assembly and an elastic component for mounting the filter assembly. The filter assembly includes a filter strip 64 and a bracket 63 for supporting the filter strip 64. One side of the filter strip 64 is attached to the outer wall of the ventilation shell 1. Three sets of LED light strips 22 arranged in a linear array are embedded on the outer wall of the connecting shell 2. The filter strip 64 can be made of materials that can effectively filter air, such as activated carbon or sponge.

[0047] The adjustment and cleaning section 5 is located above the filter section 6. The adjustment and cleaning section 5 includes a lead screw 52 located inside the ventilation housing 1. A nut slide 53 that moves along the lead screw 52 is sleeved on the outer wall of the lead screw 52. A movable disk 51 with a through hole in the center is fixedly installed at the bottom of the nut slide 53. Several brush rollers 55 for cleaning the strip ventilation holes 11 are arranged in a ring array around the through hole on the outer wall of the movable disk 51. The brush rollers 55 are located inside the strip ventilation holes 11. One end of the brush roller 55 is provided with an adjustment rod 54 that is slidably connected to the guide groove 12. The two ends of the brush roller 55 are rotatably connected to the adjustment rod 54 and the movable disk 51, respectively. The adjustment rod 54 corresponds to the filter section 6 one by one. The lower end of the adjustment rod 54 is set as an arc shape.

[0048] The collection cover 3 is located at the bottom of the connecting housing 2. The collection cover 3 has a collection block 32 that can be detachably installed inside. The top center of the collection block 32 has a placement groove 321 for placing a glass slide.

[0049] In the above scheme, the three sets of LED light strips 22 are located at the lower part of the connecting shell 2. Each set of LED light strips 22 has a number of them, and the number of LED light strips 22 are distributed in a ring array on the connecting shell 2.

[0050] Specifically, after unscrewing the collection cover 3, place a suitable-sized glass slide into the placement slot 321 of the collection block 32. After securing the glass slide with tape, apply Vaseline to the glass slide. Then, install the collection cover 3 at the bottom of the connecting housing 2, and place the spore trap in the field. After manually starting the equipment, the electric motor 74 of the control unit 7 controls the screw 52 to rotate, causing the nut slide 53 to drive the moving plate 51 upward. The moving plate 51 drives the adjusting rod 54 upward to expose the strip ventilation hole 11. At the same time, the elastic component uses the bracket 63 to drive the filter strip 64 upward, using the filter strip 64 to cover the strip ventilation hole 11. When the brushless fan 78 draws spore-containing air into the equipment, the filter strip 64 uses the brushless fan 78 to filter the air drawn in by the spores. The air inside the spore trap is filtered to prevent large particles from entering. The brushless fan 78 of the control unit 7 blows the spore-containing air into the glass slide, where petroleum jelly is applied to collect the spores. The size of the strip ventilation hole 11 can be adjusted by changing the position of the adjusting rod 54, thereby changing the air intake. When not in use, the adjusting rod 54 can block the strip ventilation hole 11 to prevent dust. When cleaning is required, the moving disk 51 drives the brush roller 55 to move up and down to clean the walls of the strip ventilation hole 11. Since the brush roller 55 is connected by a rotating mechanism, it will rotate due to friction during the up and down movement, which can further improve the cleaning effect.

[0051] It should be further explained that the spore trap can be fixed in any suitable location in the field using a support frame. Taking a T-shaped support frame as an example, there are two fixing methods: Method 1: First, insert the support frame directly into the ground to fix it, then use the handle 15 to hang the spore trap on the support frame, and finally use a rope or cloth strip to fix the handle 15 to secure the spore trap; Method 2: Similarly, first fix the support frame, then use a rope to tie the handle 15, and then fix the spore trap by tying the rope to the support frame; If trees are planted in the field, the step of fixing the support frame can be omitted, and the spore trap can be fixed by fixing the rope to a thicker branch. Regardless of whether a support frame or a tree is used to support the equipment, care should be taken not to affect the operation of the various mechanisms of the equipment.

[0052] Reference Figure 1-5 and Figure 7 To facilitate the use of this invention, the control unit 7 in the structure includes two fixed disks 71 and a connecting cylinder 72 that is detachably installed between the two fixed disks 71. One of the fixed disks 71 is fixedly connected to the inner wall of the communicating shell 2. An electric motor 74 is provided at the center of the interior of the connecting cylinder 72. The electric motor 74 is fixed to the top of the lower fixed disk 71. The output shaft of the electric motor 74 passes through the mounting through hole at the center of the upper fixed disk 71 and is rotatably connected to the upper fixed disk 71 through a bearing. The output shaft of the electric motor 74 is connected to a locking head 76.

[0053] In the above scheme, a sealing disc 16 is fixed in the lower part of the ventilation housing 1, and the top end of the lead screw 52 is rotatably connected to the top plate inside the ventilation housing 1 through a bearing. The bottom end of the lead screw 52 passes through the sealing disc 16 and is fitted with a locking seat 521. The lead screw 52 is rotatably connected to the sealing disc 16 through a bearing. A locking groove 5211 matching the locking head 76 is opened at the center of the locking seat 521, and the lead screw 52 and the output shaft of the electric motor 74 are engaged and connected through the locking head 76 and the locking groove 5211.

[0054] Specifically, when assembling the connecting housing 2 and the ventilation housing 1, the engaging head 76 is inserted into the engaging groove 5211, thereby connecting the lead screw 52 and the output shaft of the electric motor 74. During operation, the electric motor 74 is started, which drives the lead screw 52 to rotate, causing the nut slide 53 to drive the moving disk 51 to move up and down, which in turn drives the brush roller 55 and the adjusting rod 54 to move up and down. The brush roller 55, which moves up and down, cleans the strip ventilation hole 11, preventing particulate impurities such as pollen from adhering to the strip ventilation hole 11 and affecting the next spore capture. The size of the strip ventilation hole 11 can be adjusted by the adjusting rod 54, which is beneficial for controlling the air intake. At the same time, when not in use, the adjusting rod 54 can block the strip ventilation hole 11, which has a dust prevention effect.

[0055] Reference Figure 3 and Figure 7 In the structure, a ventilation channel 79 is formed between the outer wall of the connecting cylinder 72 and the inner wall of the connecting shell 2. Several ventilation holes 73 arranged in a ring array near the outer edge of the fixed plate 71 are provided to communicate with the ventilation channel 79. The ventilation channel 79 and ventilation holes 73 are used to separate the air in the suction device from the equipment in the connecting cylinder 72, thereby providing a dustproof function. At the same time, the suction air can also carry away a certain amount of heat when passing through the connecting cylinder 72, thus achieving heat dissipation.

[0056] In the above scheme, a brushless fan 78 is provided below the electric motor 74. The brushless fan 78 is fixed to the bottom center of the mounting plate 71 located at the lower part by bolts. The brushless fan 78 is used to blow air containing spores onto the glass slide. A main control board 75 for control and a lithium battery 77 for power supply are respectively provided on both sides of the electric motor 74. The main control board 75 is electrically connected to the brushless fan 78, the electric motor 74, and the LED light strip 22 through control circuits. The lithium battery 77 is electrically connected to the main control board 75, the brushless fan 78, the electric motor 74, and the LED light strip 22 through wires. The main control board 75 can be mainly manufactured using STM series chips. The main control board 75 is customized by the manufacturer according to needs or a suitable control board with appropriate functions can be selected from the market. The main control board 75 may have a positioning module and remote... The remote communication module and positioning module prevent the spore trap from being lost and facilitate the operator's retrieval of the spore trap. The remote communication module can transmit the working status of the brushless fan 78, electric motor 74, and LED light strip 22 (i.e., whether they are working properly) to the user terminal. The user terminal, such as a mobile phone or computer, can also send reminder messages to remind the user to retrieve the glass slide in time. In addition, a charging port, control buttons, and a touch screen should be provided on the connecting housing 2. The touch screen can be used to display data, such as timer information. The charging port is electrically connected to the lithium battery 77 via a wire. The control buttons are electrically connected to the main control board 75. Multiple control buttons can be set, and their functions can include starting the main control board 75 by activating the control buttons, timing the device, or selecting whether to enable remote communication.

[0057] Specifically, when using the device, the spore trap is activated, and the user manually selects the operating mode, such as timed reminders or cleaning time. After setting the relevant parameters, the user can leave. The spore trap operates by activating the brushless fan 78 via the main control board 75. The brushless fan 78 draws spore-containing air into the device and blows it onto the glass slide. When cleaning is required, the electric motor 74 is activated via the main control board 75, and the brush roller 55 cleans the strip ventilation holes 11. At night, the LED light strip 22 is activated via the main control board 75, making the LED light strip 22 light up so that the operator can easily find the spore trap at night, facilitating the recovery of the glass slide.

[0058] Reference Figure 1-3 and Figure 6In order to achieve the automatic reset effect of the bracket 63 and filter the air containing spores, the bracket 63 in the structure includes an upper contact block 631 and a lower connecting plate 633 that is slidably connected to the inner wall of the mounting box 61. The top of the upper contact block 631 is provided with an arc-shaped through groove 6311 that cooperates with the bottom end of the adjusting rod 54. Two symmetrically distributed support rods 632 are detachably installed between the bottom of the upper contact block 631 and the top of the lower connecting plate 633, and the filter strip 64 is provided with through holes that cooperate with the support rods 632.

[0059] In the above scheme, the elastic component in the structure includes a limiting post 62 and a spring 65 fixed to the bottom of the lower connecting plate 633. The bottom ends of the spring 65 and the limiting post 62 are fixedly connected to the top of the mounting box 61 base plate, and the spring 65 is sleeved on the outside of the limiting post 62.

[0060] Specifically, when the support rod 632 moves downward, it causes the bracket 63 to move downward. The bracket 63 compresses the spring 65, which acts as a buffer. At the same time, the limiting post 62 limits the bracket 63. When the support rod 632 moves upward, the spring 65 causes the bracket 63 to move upward. The bracket 63 then moves the filter strip 64 upward to cover the exposed strip-shaped ventilation hole 11. When the brushless fan 78 collects spores, the filter strip 64 filters the air drawn into the spore trap through the brushless fan 78, preventing large particles from entering the spore trap. When the filter strip 64 needs to be replaced, the upper contact block 631 can be removed to remove the filter strip 64 for replacement. The upper contact block 631 and the support rod 632 can be connected by screws.

[0061] Reference Figure 5-6 and Figure 8 In order to achieve quick assembly and disassembly of the connecting shell 2 and the ventilation shell 1, the upper part of the ventilation shell 1 is provided with a handle 15. The handle 15 facilitates the carrying and placement of the device. The bottom of the ventilation shell 1 is connected to a guide ring 13 integrally formed with the ventilation shell 1. The outer wall of the guide ring 13 is symmetrically provided with guide strips 131.

[0062] The lower part of the ventilation housing 1 is symmetrically provided with a fastening groove 14, and the upper part of the connecting housing 2 is provided with a guide groove 23 that cooperates with the guide strip 131. The outer wall of the upper part of the connecting housing 2 is symmetrically provided with a buckle 4 for connecting the connecting housing 2 and the ventilation housing 1. The connecting housing 2 and the ventilation housing 1 can be detachably connected by the cooperation of the buckle 4 and the fastening groove 14.

[0063] Specifically, by using the cooperation of the guide strip 131 and the guide groove 23, the connecting housing 2 is fitted over the guide ring 13, thus completing the positioning of the connecting housing 2. At this time, the buckle 4 is aligned with the fastening groove 14, and the adjusting rod 54 is aligned with the filter part 6. Then, the buckle 4 is used to fix the connecting housing 2 onto the ventilation housing 1, thus completing the assembly of the connecting housing 2 and the ventilation housing 1. Disassembly is convenient and facilitates later maintenance. Moreover, if a part of the present invention is damaged, only the damaged part needs to be replaced to continue using it.

[0064] Reference Figure 3 and Figure 6 In order to facilitate the placement and removal of glass slides, the bottom of the connecting shell 2 is provided with a connection port 21 integrally formed with the connecting shell 2, and the outer wall of the connection port 21 is provided with external threads.

[0065] The structure includes a conical cover 31 and a mounting port 33 fixed to the top of the conical cover 31. The inner wall of the mounting port 33 is provided with an internal thread that engages with the external thread. The collection cover 3 and the connecting shell 2 are engaged with each other through the internal thread and the external thread.

[0066] Specifically, in use, place the glass slide in the placement groove 321 of the collection block 32 inside the collection cover 3, then use tape to fix the four corners of the glass slide. After that, apply Vaseline for adhering spores to the glass slide, then put the mounting port 33 over the connecting port 21, rotate the collection cover 3, and use the threaded connection to fix the collection cover 3 to the connecting shell 2. When it is necessary to remove the glass slide, rotate the collection cover 3 in the opposite direction to remove it, then tear off the tape and use the tape to take the glass slide out.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
