Description

Technical Field

[0001] This utility model relates to the field of agricultural facility technology, and in particular to an adjustable frame for trapping insects and pests. Background Technology

[0002] Pests and diseases are insects that harm crops, forest trees, and horticultural plants. They cause crop yield reduction, quality decline, and even large-scale death by feeding on leaves, stems, and roots or spreading diseases. The damage caused by pests and diseases is characterized by its insidiousness, explosiveness, and transmissibility. The control of pests and diseases requires a combination of agricultural, physical, biological, and chemical control methods. The pest and disease trapping color board angle adjustment frame enhances the trapping efficiency of color-attracting insects by optimizing the reflection angle of the color board, thus becoming an important tool in the green control system.

[0003] The insect trap angle adjustment frame is an auxiliary device that uses a mechanical structure to adjust the tilt or rotation angle of the trap to optimize spectral reflectance efficiency and improve insect trapping effect. Existing insect traps release the movement restriction of the support joint by rotating the nut, and tilt the trap to the target angle as needed (refer to the scale markings or empirical values). However, tightening the bolts too much can cause deformation of the plastic parts of the trap, which reduces the structural stability. Existing technology achieves angle locking through the cooperation of the slot and the elastic pin. During adjustment, you only need to press the pin to manually pry the support. After positioning, the pin automatically engages the slot. However, the elasticity of the elastic pin decreases significantly after long-term use, resulting in insufficient locking force and the trap angle slipping, which affects the trapping efficiency of the trap. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an angle adjustment frame for insect trapping boards, which aims to improve the problem that when the device is rotated and fixed in the prior art using elastic pins, the elasticity of the pins is severely weakened after long-term use, resulting in insufficient locking force, causing the color board angle to slip and affecting the trapping efficiency of the color board.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an angle adjustment frame for insect and disease trapping boards, including a placement frame. A rotating mechanism is installed on the top of the outer wall of the placement frame, which is used to adjust the angle of the placement frame. A lifting mechanism is installed on the bottom of the outer wall of the placement frame, which is used to raise and lower the placement frame. The rotating mechanism includes multiple connecting blocks, which are installed on the top of the outer wall of the placement frame. A drive shaft is rotatably connected to the inner wall of each connecting block. A ratchet is fixedly connected to the right end of the outer wall of the drive shaft. A worm gear is installed on the right side of the outer wall of the ratchet. The middle part of the worm gear is fixedly connected to the right side of the outer wall of the drive shaft. A pawl is installed on the top of the outer wall of the ratchet. A limit shaft is installed on the inner wall of the pawl. A worm is installed on the bottom of the outer wall of the worm gear. The top of the outer wall of the worm gear meshes with the bottom of the outer wall of the worm gear. A knob is fixedly connected to the front end of the outer wall of the worm gear.

[0006] As a further description of the above technical solution:

[0007] The lifting mechanism includes a base plate, which is installed on the bottom of the outer wall of the placement frame. Multiple sliding plates are fixedly connected to the top left and right ends of the outer wall of the base plate. A lifting frame is installed on the top of each of the multiple sliding plates. The front end of the bottom of the lifting frame is fixedly connected to the front end of the top of the outer wall of the sliding plate. A slider is fixedly connected to the rear end of the bottom of the lifting frame. A drive assembly is installed on the top of the outer wall of the base plate.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a hydraulic rod, which is mounted on the top of the outer wall of the base plate. The output end of the hydraulic rod is fixedly connected to a connecting plate, and the left and right sides of the outer wall of the connecting plate are fixedly connected to the outer wall of the lifting frame.

[0010] As a further description of the above technical solution:

[0011] A bracket is installed at the bottom of the outer wall of the worm gear, and the upper middle inner wall of the bracket is rotatably connected to the outer wall of the worm gear.

[0012] As a further description of the above technical solution:

[0013] A baffle is fixedly connected to the front end of the hydraulic rod, and the bottom of the outer wall of the baffle is fixedly connected to the top front end of the outer wall of the base plate.

[0014] As a further description of the above technical solution:

[0015] The top of each of the multiple sliding plates is provided with a groove, and the inner wall of the groove is slidably connected to the outer wall of the slider.

[0016] As a further description of the above technical solution:

[0017] A bracket is installed on the outer side of the placement rack, and the inner wall of the upper middle part of the bracket is rotatably connected to the outer wall of the drive shaft.

[0018] As a further description of the above technical solution:

[0019] A light-transmitting mirror is installed on the bottom outer side of the rotating mechanism, and the outer wall of the light-transmitting mirror is fixedly connected to the top outer wall of the placement frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the drive shaft rotates, it drives the placement frame to rotate. When it reaches the designated position, the pawl at the top of the ratchet plays a limiting role, keeping the entire device stationary. When the placement frame needs to be returned to its original position, the pawl is lifted, and the placement frame rotates back to its initial position under the action of gravity. This structure replaces the traditional elastic pin, solving the problem that after long-term use, the elasticity of the elastic pin weakens and the locking force is insufficient, causing the color plate angle to slide on its own, thereby reducing the capture efficiency of the trapping color plate.

[0022] 2. In this utility model, after the hydraulic rod is activated, the groove at the top of the slide plate restricts the movement trajectory of the slider, allowing it to slide only along the groove, thus ensuring the smooth operation of the lifting mechanism. The baffle at the front end of the hydraulic rod provides stable support and enhances the reliability of the mechanism. This design abandons the traditional snap-on adjustment frame, overcomes the defect that its upright positioning holes are evenly distributed, which makes it impossible to continuously adjust the height, avoids the discrepancy between the actual height and the requirements, and achieves precise and flexible height adjustment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a pest and disease trap angle adjustment frame, including a placement frame 1. A rotating mechanism 2 is installed on the top of the outer wall of the placement frame 1 for adjusting the angle of the placement frame 1. A lifting mechanism 3 is installed on the bottom of the outer wall of the placement frame 1 for raising and lowering the placement frame 1. The rotating mechanism 2 includes multiple connecting blocks 201, which are installed on the top of the outer wall of the placement frame 1. A drive shaft 202 is rotatably connected to the inner wall of the connecting blocks 201. A ratchet 203 is fixedly connected to the right end of the outer wall of the drive shaft 202. A worm gear 204 is installed on the right side of the outer wall of the ratchet 203. The middle part of 04 is fixedly connected to the right side of the outer wall of the drive shaft 202. A pawl 205 is installed on the top of the outer wall of the ratchet 203. A limit shaft 206 is installed on the inner wall of the pawl 205. A worm 207 is installed on the bottom of the outer wall of the worm gear 204. The top of the outer wall of the worm 207 is meshed with the bottom of the outer wall of the worm gear 204. A knob 208 is fixedly connected to the front end of the outer wall of the worm 207. A bracket 209 is installed on the bottom of the outer wall of the worm 207. The upper middle inner wall of the bracket 209 is rotatably connected to the outer wall of the worm 207. A bracket 4 is installed on the outside of the placement frame 1. The upper middle inner wall of the bracket 4 is rotatably connected to the outer wall of the drive shaft 202.

[0032] Specifically, the knob 208 is welded to the worm gear 207 as a single unit. Power transmission is achieved through the precise meshing of the worm gear 207 and the worm wheel 204. When the knob 208 is rotated, the rotational power is transmitted to the worm wheel 204 via the worm gear 207, driving the worm wheel 204 to rotate around its axis. A drive shaft 202 is welded to the middle of the worm wheel 204, and a ratchet 203 is installed on the outside of the drive shaft 202. Therefore, when the worm wheel 204 rotates, it synchronously drives the drive shaft 202 and the ratchet 203 to rotate. The bracket 209 installed on the outside of the worm gear 207 is fixed to the bracket 4, providing stable support for the worm gear 207 and ensuring the stability of the meshing transmission. The connecting block 201 on the outside of the drive shaft 202 is rigidly connected to the placement frame 1. When 202 rotates, it drives the placement rack 1 to rotate as needed. When the placement rack 1 rotates to the designated position, the pawl 205 on the top of the ratchet 203 engages with the tooth groove of the ratchet 203, keeping the entire device stationary through mechanical limiting. The limiting shaft 206 welded inside the pawl 205 is fixed to the outside of the bracket 4, restricting the pawl 205 to rotate only around the limiting shaft 206, ensuring its limiting action is accurate. If the placement rack 1 needs to be returned to its original position, simply lift the pawl 205 upwards to release the lock, and the placement rack 1 will automatically rotate to the initial position under the action of gravity. This design solves the problem that after long-term use, the elasticity of the traditional elastic pin will decrease, resulting in insufficient locking force, self-slip of the trapping color plate angle, and affecting the capture efficiency.

[0033] Reference Figure 2 , Figure 3 and Figure 5 The lifting mechanism 3 includes a base plate 301, which is installed on the bottom of the outer wall of the placement frame 1. Multiple sliding plates 302 are fixedly connected to the top left and right ends of the outer wall of the base plate 301. A lifting frame 305 is installed on the top of the multiple sliding plates 302. The bottom front end of the outer wall of the lifting frame 305 is fixedly connected to the top front end of the outer wall of the sliding plate 302. A slider 304 is fixedly connected to the bottom rear end of the outer wall of the lifting frame 305. A drive assembly 306 is installed on the top of the outer wall of the base plate 301. The drive assembly 306 includes a hydraulic rod 3061, which is installed on the top of the outer wall of the base plate 301. A connecting plate 3063 is fixedly connected to the output end of the hydraulic rod 3061. The left and right sides of the outer wall of the connecting plate 3063 are fixedly connected to the outer wall of the lifting frame 305.

[0034] Specifically, the output end of the hydraulic rod 3061 is welded to the connecting plate 3063 to form a stable connection. Slide plates 302 are symmetrically installed on the top of the base plate 301 to provide a guiding foundation for the lifting movement. Both ends of the connecting plate 3063 are welded to the lifting frame 305, constructing a rigid linkage structure to ensure that the two lifting frames 305 rise and fall synchronously during operation. When the hydraulic rod 3061 is activated, its output power drives the connecting plate 3063 to move, causing the lifting frame 305 to move vertically. During this process, the groove 303 on the top of the slide plate 302 plays a crucial role. The groove 303 closely cooperates with the slider 304 installed at the bottom of the lifting frame 305, allowing the sliding motion to proceed smoothly. The movement trajectory of slider 304 is restricted by 303, so that slider 304 can only slide along the inside of groove 303, thereby effectively preventing the lifting frame 305 from deviating or shaking during the lifting process, and further improving the overall stability and accuracy of the lifting mechanism 3. The baffle 3062 installed at the front end of hydraulic rod 3061 provides reliable support for hydraulic rod 3061 and enhances its stability during operation. This design completely solves the drawbacks of traditional snap-on adjustment frames. In the past, the positioning holes on the upright of the snap-on adjustment frame were evenly distributed, which resulted in height adjustment being limited to fixed intervals, failing to meet the needs of continuous height adjustment, and causing a deviation between the actual adjusted height and the usage requirements.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A light-transmitting mirror 5 is installed on the bottom outer side of the rotating mechanism 2. The outer wall of the light-transmitting mirror 5 is fixedly connected to the top of the outer wall of the placement frame 1. It has a converging effect on parallel light and can focus the dispersed sunlight onto the center of the color plate, making the color plate more vibrant and increasing its attractiveness to pests.

[0036] Specifically, at the bottom outer side of the rotating mechanism 2, the light-transmitting mirror 5 is precisely installed and positioned. Its outer wall is tightly connected to the top outer wall of the placement frame 1 through a fixed connection, forming a stable optical component structure. With its unique curved surface structure, the light-transmitting mirror 5 has the characteristic of converging parallel light, thereby effectively enhancing the visual attraction of the color board to pests and optimizing the trapping effect.

[0037] Working principle: Rotating knob 208 causes the placement rack 1 to rotate and be fixed as needed. Knob 208 engages with worm gear 207 and worm wheel 204 to drive the worm wheel 204. When knob 208 is rotated, its power is transmitted through worm gear 207 to worm wheel 204, causing it to rotate. A drive shaft 202 is welded to the middle of worm wheel 204, and a ratchet 203 is mounted on the outside of drive shaft 202. Therefore, when worm wheel 204 rotates, it drives drive shaft 202 and ratchet 203 to rotate synchronously. The bracket 209 mounted on the outside of worm wheel 204 is fixed to bracket 4, providing stable support for worm gear 207. The connecting block 201 mounted on the outside of drive shaft 202... The placement rack 1 is connected, so when the drive shaft 202 rotates, it will synchronously drive the placement rack 1 to rotate as needed. When it rotates to the designated position, the entire device will be stationary due to the restriction of the pawl 205 installed on the top of the ratchet 203. The limiting shaft 206 welded inside the pawl 205 is fixed to the outside of the bracket 4, which can limit the displacement of the pawl 205 so that it can only rotate. When it is necessary to return the placement rack 1 to its original position, simply lift the pawl 205, and the placement rack 1 will rotate back to its original position under the action of gravity. This solves the problem that when the device is rotated and fixed by the elastic pin, its elasticity will be severely weakened after long-term use, resulting in insufficient locking force, and the color plate angle will slip, affecting the capture efficiency of the trapping color plate.

[0038] The height of the placement frame 1 is adjusted by raising and lowering the lifting frame 305 by activating the hydraulic rod 3061. Because the output end of the hydraulic rod 3061 is welded with a connecting plate 3063, and a sliding groove plate 302 is installed on the top of the base plate 301, the two ends of the connecting plate 3063 are welded to the lifting frame 305 to achieve linkage. The two lifting frames 305 will rise and fall synchronously. When the hydraulic rod 3061 is activated, due to the restriction of the groove 303 opened on the top of the sliding groove plate 302, the slider 304 can only slide along the inside of the groove 303, further improving the stability of the lifting mechanism 3. The baffle 3062 installed at the front end of the hydraulic rod 3061 can provide sufficient support for it, solving the problem that when using a snap-on adjustment frame to adjust the height of the device, the positioning holes on the upright are evenly distributed, which cannot achieve continuous height adjustment, resulting in a deviation between the actual height and the requirement.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
