[0023] refer to Figure 3 The limiting assembly 6 includes a limiting groove 61, which is opened on both sides of the left side of the positioning magnetic plate 5. The limiting groove 61 is internally slidably connected to a limiting rod 62, and the right side of the limiting rod 62 is fixedly connected to both sides of the left side of the air outlet seat 3.

[0024] As a technical optimization scheme of the utility model, by setting a limit assembly 6, when the user moves the air outlet seat 3, the air outlet seat 3 will drive the limit rod 62 to move, and then the limit rod 62 and the limit groove 61 are slidably matched to limit the moving trajectory of the air outlet seat 3 front, back, up and down, so as to avoid the air outlet seat 3 from being offset during the movement.

[0025] refer to Figure 2 The auxiliary cleaning component 7 includes a scraper bar 71 , the bottom of the scraper bar 71 is slidably connected to the rear side of the top of the weighing device body 1 , and the front of the scraper bar 71 is fixedly connected to a pull rope 72 .

[0026] As a technical optimization solution of the utility model, by setting up the auxiliary cleaning component 7, the user can pull the pull rope 72 to move toward the front, so that the pull rope 72 drives the scraper 71 to move toward the front, and then the pull rope 72 will drive the scraper 71 to move toward the front, and then the scraper 71 will scrape away foreign matter on the front and rear sides of the top of the weighing device body 1, further improving the cleaning effect.

[0027] refer to Figure 2 Guide blocks 8 are fixedly connected to both sides of the back of the scraper strip 71 , and guide grooves 9 are opened on both sides of the top of the weighing device body 1 , and the inner wall of the guide groove 9 is slidably connected to the surface of the guide block 8 .

[0028] As a technical optimization solution of the utility model, by setting the guide block 8 and the guide groove 9, the user can utilize the sliding cooperation of the guide block 8 and the guide groove 9 to limit the movement of the scraper 71 to the left and right, thereby avoiding the scraper 71 from being offset during the movement, resulting in the scraper 71 being unable to move smoothly.

[0029] Referring to 2 , the front side of the top of the weighing device body 1 is fixedly connected to a limit seat 10 , and the inner wall of the limit seat 10 is slidably connected to the surface of the pull rope 72 .

[0030] As a technical optimization solution of the utility model, by setting a limit seat 10 and utilizing the sliding cooperation between the pull rope 72 and the limit seat 10, the end of the pull rope 72 away from the scraper strip 71 can be limited left and right and up and down to prevent the end of the pull rope 72 away from the scraper strip 71 from shaking randomly, resulting in the situation that the position of the pull rope 72 is not fixed enough.

[0031] refer to Figure 2 One end of the pull rope 72 away from the scraper strip 71 is fixedly connected to the limited force application plate 11, and the material of the limited force application plate 11 is PP plastic.

[0032] As a technical optimization scheme of the utility model, by setting a limit force plate 11, when the user needs to pull the pull rope 72, the user can directly pull the pull rope 72 by holding the limit force plate 11. At the same time, the limit force plate 11 can be used to limit the end of the pull rope 72 away from the scraper strip 71 to avoid the pull rope 72 from being separated from the limit seat 10. The advantage of the low cost of PP plastic is then utilized to reduce the use cost of the limit force plate 11.

[0033] refer to Figure 2 A connecting plate 12 is fixedly connected to the back of the weighing device body 1 , an elastic rope 13 is fixedly connected to the top of the connecting plate 12 , and one end of the elastic rope 13 away from the connecting plate 12 is fixedly connected to the back of the scraper strip 71 .

[0034] As a technical optimization solution of the utility model, by providing a connecting plate 12 and an elastic rope 13, the user can pull the elastic rope 13 when moving the scraper strip 71 toward the front, and then the elastic rope 13 will be pulled to generate a rebound force, and then the elastic rope 13 will pull back the scraper strip 71. After the user releases the pull rope 72, the elastic rope 13 can be used to quickly pull the scraper strip 71 to its original position.

[0035] The working principle and use process of the utility model are as follows: before the user needs to place the agricultural products on the weighing tray 2 and use the weighing device body 1 to weigh them, the user first opens the solenoid valve 4, and then the solenoid valve 4 conducts the air flow of the air source to the air outlet seat 3 through the conduit and the solenoid valve 4, and then the user moves the air outlet seat 3 to the right and close to the left side of the bottom of the weighing tray 2, and then the air outlet seat 3 guides the air flow and blows out the foreign matter between the weighing tray 2 and the weighing device body 1, so as to avoid the foreign matter blocking the weighing data of the agricultural products by the weighing device body 1. When the user moves the air outlet seat During the process of cleaning, the air outlet seat 3 will drive the limiting rod 62 to move, and then the limiting rod 62 will slide with the limiting groove 61 to limit the moving trajectory of the air outlet seat 3 in the front, back and up and down directions, so as to avoid the air outlet seat 3 from deviating during the movement. Then the user can pull the pull rope 72 to move toward the front, so that the pull rope 72 drives the scraper 71 to move toward the front, and then the pull rope 72 will drive the scraper 71 to move toward the front, and then the scraper 71 will scrape away foreign matter on the front and rear sides of the top of the weighing device body 1, thereby further improving the cleaning effect and having the ability of auxiliary cleaning. To sum up: the agricultural product wholesale weighing device based on the Internet of Things, by setting the air outlet seat 3, opens the solenoid valve 4, and then the solenoid valve 4 will conduct the airflow of the air source to the air outlet seat 3 through the conduit and the solenoid valve 4, and then the user moves the air outlet seat 3 to the right close to the left side of the bottom of the weighing tray 2, and then the air outlet seat 3 will conduct the airflow and blow out the foreign matter between the weighing tray 2 and the weighing device body 1, which solves the problem that the weighing device used for weighing agricultural products lacks a corresponding protective structure, resulting in some foreign matter falling into the gap on the weighing device, which will cause the activity space between the weighing tray on the weighing device and the weighing device to be blocked by foreign matter, causing errors in the weighing data.
