Description

Technical Field

[0001] This utility model belongs to the field of locust suction machine technology, specifically relating to a suction nozzle mechanism for a locust suction machine. Background Technology

[0002] Existing locust trapping machines typically have a main baffle at the bottom of the collection tube to prevent locusts from escaping. However, during the trapping process, some locusts do escape from the sides of the collection tube. Therefore, some existing trapping machines also have side baffles on both sides of the collection tube to mitigate this escape. However, because the main baffle and the two side baffles are independently configured, locusts can still escape through the gaps between the baffles during the trapping process. Furthermore, this can cause vibration in the baffles, reducing their lifespan. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a suction nozzle mechanism for a locust trapping machine.

[0004] To achieve the above objectives, this utility model discloses a suction nozzle mechanism for a locust trapping machine, including a support, a suction cylinder, a collection cylinder, and a main baffle.

[0005] The suction cylinder has multiple suction cylinders, which are installed side by side on the bracket. The collecting cylinder is set vertically, and the upper port of the collecting cylinder is sealed to the lower port of the multiple suction cylinders. The lower port of the collecting cylinder is the suction port. Side baffles are provided on both sides of the collecting cylinder along its length. The main baffle is installed on the bracket and is inclined to the side away from the collecting cylinder. At least part of the main baffle is located below the suction port.

[0006] An arc-shaped baffle is provided between the main baffle and the two side baffles. The two sides of the arc-shaped baffle are connected to the main baffle and the corresponding side baffle, respectively, to completely seal the gap between the main baffle and the corresponding side baffle.

[0007] Preferably, the arc-shaped baffle completely covers the gap between the main baffle and the corresponding side baffle.

[0008] Preferably, the shape of the arc-shaped baffle is the same as the shape of the gap between the main baffle and the corresponding side baffle.

[0009] Preferably, the bottom surface of the arc-shaped baffle and the side baffle is higher than the bottom surface of the main baffle.

[0010] Preferably, the two sides of the arc-shaped baffle are welded to the main baffle and the corresponding side baffle, respectively.

[0011] Preferably, the two sides of the arc-shaped baffle are detachably connected to the main baffle and the corresponding side baffle, respectively.

[0012] Preferably, the main baffle is detachably connected to the bracket.

[0013] Preferably, the bracket includes a mounting frame and a connecting frame rotatably connected to the mounting frame, wherein the plurality of suction cylinders, collector cylinders and main baffle are mounted on the mounting frame, and the connecting frame is used to connect to the equipment.

[0014] Preferably, the mounting bracket is provided with a U-shaped limiting part, the opening of the limiting part is opposite to the connecting bracket, the two side walls of the limiting part are provided with corresponding connecting holes, and a limiting pin is provided in the two opposite connecting holes, the limiting pin is engaged with the connecting bracket for limiting.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] An arc-shaped baffle is installed between the main baffle and each of the two side baffles. The two sides of the arc-shaped baffle connect to the main baffle and the corresponding side baffle, respectively, to completely seal the gap between them. This eliminates the gaps and prevents locusts from escaping, improving locust capture efficiency. Furthermore, the arc-shaped baffles connect the main baffle and the corresponding arc-shaped baffles together, reinforcing them and reducing vibration and shaking during use, thus extending their service life.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] A suction nozzle mechanism for a locust trapping machine, see [link / reference]. Figures 1-3The system includes a support 100, suction cylinders 200, a collector cylinder 300, and a main baffle 400. Multiple suction cylinders 200 are arranged side-by-side on the support 100. The upper port of each suction cylinder 200 is connected to a negative pressure adsorption device, enabling the suction nozzle mechanism to perform suction operations. The collector cylinder 300 is vertically oriented, with its upper port sealed to the lower ports of the multiple suction cylinders 200. The lower port of the collector cylinder 300 serves as a suction port 310. Side baffles 320 are provided on both sides along the length of the collector cylinder 300. The main baffle 400 is mounted on the support 100, tilted away from the collector cylinder 300, and at least a portion of the main baffle 400 is located below the suction port 310. An arc-shaped baffle 500 is provided between the main baffle 400 and each of the two side baffles 320. The two sides of the arc-shaped baffle 500 are connected to the main baffle 400 and the corresponding side baffle 320, respectively, to completely seal the gap between them. This eliminates the gap, preventing locusts from escaping and improving locust capture efficiency. Furthermore, the arc-shaped baffle 500 connects the main baffle 400 and the corresponding side baffles 320, reinforcing them and reducing vibration and shaking during use, thus extending their service life.

[0023] Among them, the collector cylinder 300 is a rectangular cylinder, the suction cylinder 200 is a horn shape that is narrow at the top and wide at the bottom, and the lower port is a rectangular port. The lower ports of multiple suction cylinders 200 are rectangular openings. After multiple suction cylinders 200 are arranged side by side, they can be sealed and connected to the upper port of the collector cylinder 300.

[0024] In this embodiment, the arc-shaped baffle 500 completely covers the gap between the main baffle 400 and the corresponding side baffle 320. By completely covering the gap, the possibility of locusts escaping through any tiny gap between the main baffle 400 and the side baffle 320 is completely eliminated, further improving the locust-catching efficiency. At the same time, the full-coverage design enhances the overall structural strength of the baffle assembly and reduces the risk of deformation caused by uneven local stress.

[0025] Preferably, the shape of the arc-shaped baffle 500 is the same as the shape of the gap between the main baffle 400 and the corresponding side baffle 320, so that the arc-shaped baffle 500 and the gap shape are precisely matched, ensuring that the baffle and the gap fit seamlessly and avoiding the creation of new escape channels due to shape differences; in addition, this also optimizes the airflow distribution, reduces turbulence interference during the suction process, and improves the suction stability.

[0026] In this embodiment, the bottom surfaces of the arc-shaped baffle 500 and the side baffle 320 are higher than the bottom surface of the main baffle 400. This reduces the frictional resistance between the arc-shaped baffle 500 and the side baffle 320 and the ground during operation, making it easier for the equipment to move in complex terrain, while also preventing the baffles from touching the ground and wearing down, thus improving the service life of the baffles.

[0027] In this embodiment, the two sides of the arc-shaped baffle 500 are welded to the main baffle 400 and the corresponding side baffle 320, respectively. The welding connection ensures the integrated rigidity of multiple baffles, significantly reduces the vibration transmission effect, and extends the service life. In addition, it can also prevent small locusts from seeping out from the connection and reduce the maintenance frequency.

[0028] In other alternative embodiments, the two sides of the arc-shaped baffle 500 are detachably connected to the main baffle 400 and the corresponding side baffle 320, respectively, for example by bolt connection. This facilitates quick replacement when the baffle is partially damaged, reduces maintenance costs, and allows for flexible adjustment of the baffle configuration according to the working environment (such as replacing baffles with different arcs), enhancing the adaptability of the equipment.

[0029] In this embodiment, the main baffle 400 is detachably connected to the bracket 100, specifically by bolts. This detachable connection allows for easy maintenance and replacement of the main baffle 400, reducing maintenance costs and facilitating the cleaning of insect remains on the main baffle 400.

[0030] In this embodiment, the support 100 includes a mounting frame 110 and a connecting frame 120 rotatably connected to the mounting frame 110. Multiple suction cylinders 200, a collector cylinder 300, and a main baffle 400 are mounted on the mounting frame 110, and the connecting frame 120 is used to connect to the equipment. The mounting frame 110 and the connecting frame 120 can rotate relative to each other, allowing the suction nozzle mechanism to be adjusted at multiple angles to adapt to crops or terrains of different heights.

[0031] Specifically, the bottom of the connecting bracket 120 is hinged to the mounting bracket 110. The mounting bracket 110 has a U-shaped limiting part 111, the opening of which is opposite to the connecting bracket 120. The two side walls of the limiting part 111 have corresponding connecting holes 112, and a limiting pin 113 is provided in each of the two opposite connecting holes 112. The limiting pin 113 engages with the connecting bracket 120 for limiting. During assembly, the connecting bracket 120 is inserted into the U-shaped opening of the limiting part 111, and then inserted into the two opposite connecting holes 112, thus limiting the connecting bracket 120 within the connecting part. When it is necessary to adjust the operating angle of the bracket 100, the limiting pin 113 is inserted into the other pair of connecting holes 112, thereby changing the angle between the mounting bracket 110 and the connecting bracket 120.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
