[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A conveying device for packaging wettable powder pesticides includes a workbench 1, a conveying trough 2 inside the workbench 1, a conveyor belt 3 inside the conveying trough 2, adaptive adjustment conveying mechanisms 4 on both sides of the top of the workbench 1, and a leak-proof sealing conveying assembly 5 on the top of the workbench 1.

[0027] The adaptive adjustment conveying mechanism 4 includes several mounting blocks 41, the bottom of which is bolted to the top of the workbench 1. Electric push rods 42 are provided inside the mounting blocks 41, and limit baffles 43 are bolted between one side of the electric push rods 42.

[0028] In this embodiment: The operator places the wettable powder pesticide package onto the conveyor belt 3 inside the conveyor trough 2 of the workbench 1, and then starts the adaptive adjustment conveying mechanism 4. Several mounting blocks 41 of this mechanism are bolted to the top of the workbench 1. When adjustment is needed according to the width of the packaged product, the electric push rods 42 inside the mounting blocks 41 start working and extend and retract. Since the limit baffles 43 are bolted between one side of several electric push rods 42, the extension and retraction of the electric push rods 42 causes the limit baffles 43 to move. If the package is wider, the electric push rods 42 extend, increasing the distance between the two limit baffles 43; if the package is narrower, the electric push rods 42 shorten, reducing the distance. This achieves stable conveying of packaged products of different widths. At the same time, the leak-proof sealing conveying assembly 5 set on the top of the workbench 1 is also in operation to ensure that the pesticide does not leak during the conveying process.

[0029] Specifically, such as Figure 1 , Figure 2 As shown, the top of the workbench 1 is covered with a glass protective cover 51, and the bottom of the glass protective cover 51 is bolted to the top of the workbench 1.

[0030] Specifically, such as Figure 2 As shown, a filter hole 52 is provided on the front side of the glass protective cover 51, and a first air filter element 53 is installed inside the filter hole 52.

[0031] Specifically, such as Figure 2 As shown, an air extractor 54 is bolted to the top of the glass protective cover 51. A recovery filter box 55 is fixedly connected to the left side of the air extractor 54. An air extraction pipe 56 is fixedly connected between the left side of the recovery filter box 55 and the top of the glass protective cover 51. A second air filter element 57 is provided inside the recovery filter box 55.

[0032] In this embodiment: A glass protective cover 51 is placed on top of the workbench 1 and bolted to it, forming a unique sealed conveying channel. This effectively prevents pesticide powder leakage caused by vibration, ensuring the safety of the surrounding environment and operators. The front filter hole 52 of the glass protective cover 51 contains a first air filter element 53, which can initially filter the outside air, removing dust and impurities and preventing external pollutants from mixing into the pesticide packaging. The exhaust fan 54 at the top of the glass protective cover 51 extracts the internal air through the exhaust pipe 56 and sends it into the recycling filter box 55. The second air filter element 57 in the box further filters the air. If a small amount of pesticide powder leaks, it will be sucked in and intercepted under negative pressure, realizing dust recovery. The purified air is discharged, reducing pollution and raw material waste. In addition, the operator can observe the conveying situation at any time through the transparent observation window of the sealed cover.

[0033] Specifically, such as Figure 5 , Figure 2As shown, a placement platform 6 is provided on the front and rear sides of the left side inside the workbench 1. A pressure sensor 7 is bolted to the top of the placement platform 6, and a controller 8 is bolted to the front side of the workbench 1.

[0034] Specifically, such as Figure 5 As shown, a fixing block 9 is bolted to the top of the pressure sensor 7, and a pressure measuring roller 10 is rotatably arranged between the two fixing blocks 9. The surface of the pressure measuring roller 10 is in contact with the inner wall of the conveyor belt 3.

[0035] In this embodiment: The placement platform 6 is installed on the front and rear sides of the left side inside the workbench 1. A pressure sensor 7 is fixed on its top. A pressure measuring roller 10 is rotatably mounted on the top of the sensor via a fixing block 9. The surface of the pressure measuring roller 10 contacts the inner wall of the conveyor belt 3. When the wettable powder of pesticide passes through the conveyor belt 3, the weight of the package causes the conveyor belt 3 to apply pressure to the pressure measuring roller 10. The pressure is transmitted to the pressure sensor 7 through the pressure measuring roller 10. The pressure sensor 7 converts the pressure signal into an electrical signal and transmits it to the controller 8 on the front side of the workbench 1. The controller 8 analyzes the pressure signal. If the package is heavy and the pressure exceeds the preset normal range, it issues a command to adjust the speed of the motor 15 and reduce the running speed of the conveyor belt 3 to ensure stable conveying. If the package is light and the pressure is within the normal range, it maintains the current speed of the motor 15 to ensure conveying efficiency.

[0036] Specifically, such as Figure 2 As shown, several through holes 11 are provided on the front and rear sides of the glass protective cover 51, and the electric push rod 42 extends into the glass protective cover 51 through the through holes 11.

[0037] Specifically, such as Figure 4 As shown, several support rollers 12 are rotatably arranged inside the conveyor trough 2. Power rollers 13 and driven rollers 14 are rotatably arranged on both sides inside the conveyor trough 2. The surfaces of the support rollers 12, power rollers 13 and driven rollers 14 are in contact with the inner wall of the conveyor belt 3. A motor 15 is bolted to the left side of the front side of the workbench 1. The output shaft of the motor 15 extends into the workbench 1 and is bolted to the power rollers 13.

[0038] In this embodiment: the through holes 11 on the front and rear sides of the glass protective cover 51 provide a passage for the electric push rod 42 to pass through. The electric push rod 42 extends from the mounting block 41 into the cover and drives the limiting baffle 43 without damaging the sealing structure, ensuring the normal operation of the adaptive adjustment conveying mechanism 4. The conveying groove 2 is equipped with a support roller 12, a power roller 13, and a driven roller 14, the surfaces of which are in contact with the inner wall of the conveyor belt 3. The motor 15 starts and drives the power roller 13 to rotate, driving the conveyor belt 3 through friction. The driven roller 14 rotates passively to assist the circulation. The support roller 12 supports the conveyor belt 3 to prevent it from sagging or shaking due to carrying pesticide packaging, ensuring that the packaging is transported smoothly. After the pressure sensor 7 detects different weights of packaging, the controller 8 adjusts the speed of the motor 15 according to the signal, changes the speed of the power roller 13, and automatically adjusts the speed of the conveyor belt 3 to ensure stable and efficient conveying.

[0039] Working principle: After the operator places the wettable powder pesticide package onto the conveyor belt 3 of the conveyor trough 2 inside the workbench 1 and starts the adaptive adjustment conveying mechanism 4, the bottom of the mounting block 41 in the mechanism is bolted to the top of the workbench 1. When adjustment is needed according to the width of the packaged product, the electric push rod 42 inside the mounting block 41 extends and retracts. Because a limit baffle 43 is bolted to one side of the electric push rod 42, its extension and retraction causes the limit baffle 43 to move. When the package is wide, the electric push rod 42 extends to increase the distance; when the package is narrow, the electric push rod 42 shortens to decrease the distance, achieving stable conveying of packages of different widths. The leak-proof sealing conveying assembly 5 on top of workbench 1 is also in operation. A glass protective cover 51 covers the top of workbench 1 and is bolted to it to form a sealed conveying channel to prevent pesticide powder leakage. Outside air enters after being initially filtered by the first air filter element 53 in the filter hole 52 on the front side of the glass protective cover 51. The top exhaust fan 54 extracts the internal air through the exhaust pipe 56 and sends it to the recovery filter box 55. The second air filter element 57 in the box further filters the air. A small amount of leaked pesticide powder is sucked in and intercepted under negative pressure. After purification, the air is discharged. The operator can also pass through the sealed air... The transparent observation window of the cover allows observation of the conveying process. The placement platform 6 is installed on the front and rear sides of the left side inside the workbench 1. The pressure sensor 7 on its top rotates through the top fixing block 9 and contacts the inner wall of the conveyor belt 3 with the pressure measuring roller 10. When the package passes through, its weight causes the conveyor belt 3 to apply pressure to the pressure measuring roller 10. The pressure is transmitted to the pressure sensor 7 and converted into an electrical signal, which is then transmitted to the controller 8. The controller 8 analyzes the signal. If the package is heavy and the pressure exceeds the preset range, the speed of the motor 15 is reduced. If the package is light and the pressure is normal, the current speed is maintained. The glass protective cover 51 has holes 1 on the front and rear sides. 1 provides a passage for the electric push rod 42, which extends from the mounting block 41 to the drive limiting baffle 43 inside the cover. The surfaces of the support roller 12, power roller 13, and driven roller 14 in the conveyor trough 2 contact the inner wall of the conveyor belt 3. The motor 15 drives the power roller 13 to rotate, which drives the conveyor belt 3 through friction. The driven roller 14 assists in circulation. The support roller 12 prevents the conveyor belt 3 from sagging or shaking. The controller 8 adjusts the speed of the motor 15 and changes the speed of the power roller 13 according to the signal from the pressure sensor 7, so as to realize the automatic adjustment of the speed of the conveyor belt 3 and ensure stable and efficient conveying.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
