[0023] By starting the first electric push rod 101, the baffle plate 102 can be driven to move up and down, so as to achieve the effect of exposing or covering the feed port of the sandblasting machine 1. When covering, it can prevent the ejected sand and gravel from being discharged from the feed port. When exposing, the first motor 204 can be started to drive the connecting plate 202 to rotate, so as to rotate the discharge table 203 located above the placement table 2 to the inside of the sandblasting machine 1, so as to achieve the purpose of transferring the unprocessed weeder blade into the sandblasting machine 1 for sandblasting treatment, and rotating the processed weeder blade to the top of the placement table 2 for easy removal and replacement;

[0024] See also Figure 1-4A second electric push rod 405 is arranged on the top of the connecting frame 404, a mounting plate 407 is arranged on the bottom of the connecting frame 404, an output shaft of the second electric push rod 405 passes through the connecting frame 404 and is fixedly connected to the top of the mounting plate 407, a guide rod 406 is fixedly connected to the top of the mounting plate 407, an upper end of the guide rod 406 passes through the connecting frame 404, a pressing plate 409 is arranged on the bottom of the mounting plate 407, and electromagnets 413 evenly distributed are fixedly connected to the bottom of the pressing plate 409, and through holes 408 are opened on the surfaces of the pressing plate 409 and the mounting plate 407, and the through holes 408 The aperture is larger than the diameter of the discharge rod 3, the top of the mounting plate 407 is fixedly connected with evenly distributed mounting cylinders 410, the interior of the mounting cylinder 410 is provided with a connecting rod 411, the lower end of the connecting rod 411 passes through the mounting cylinder 410 and the mounting plate 407 in sequence and is fixedly connected to the top of the pressing plate 409, the surface of the connecting rod 411 is sleeved with a spring 412, the upper end of the spring 412 is fixedly connected to the bottom of the mounting plate 407, the lower end of the spring 412 is fixedly connected to the top of the pressing plate 409, and the upper end of the connecting rod 411 is fixedly connected with a sealing plate slidably connected to the inner wall of the mounting cylinder 410;

[0025] By starting the second motor 402, the rotating rod 403 can be driven to rotate, so as to adjust the positions of the two connecting frames 404. The two connecting frames 404 arranged at an angle of ninety degrees can align one of them with the discharge table 203 above the placement table 2, and the other with one of the discharge rods 3. The discharge rod 3 is used to stack the lawn mower blades. By starting the second electric push rod 405, the mounting plate 407 can be driven to move downward. In this process, the pressure plate 409 can be driven to move downward synchronously under the action of the spring 412 and gravity. At the same time, the electromagnet 413 is energized until the electromagnet 413 contacts the surface of the lawn mower blade and can adsorb the lawn mower blade under the action of magnetic force. The setting of the through hole 408 can prevent the discharge rod 3 from affecting the pressure plate 409 and the mounting plate 40 7 moves downward, and the electromagnet 413 absorbs the weeder blade and the second electric push rod 405 is reset, so as to achieve the effect of moving the absorbed weeder blade upward. At this time, the second motor 402 drives the rotating rod 403 to rotate, so as to adjust the positions of the two connecting frames 404, so that the unprocessed weeder blade moves to the top of the discharge table 203, and the processed weeder blade is transferred to the top of another discharge rod 3, and the second electric push rod 405 drives the mounting plate 407 to reset. At this time, the electromagnet 413 is powered off, and the effect of transferring the weeder blade can be achieved. After the transfer is completed, the second electric push rod 405 drives the mounting plate 407 to reset, and at the same time, the second motor 402 drives the rotating rod 403 to reset the connecting frame 404 for reuse;

[0026] See also Figure 1-4A temporary storage chamber is formed between the bottom of the sealing plate and the inner wall of the mounting cylinder 410, a connecting pipe 416 connected to the temporary storage chamber is connected to the surface of the mounting cylinder 410, a conduit 415 connected to the temporary storage chamber is connected to the top of the mounting cylinder 410, the other end of the conduit 415 passes through the mounting plate 407 and is fixedly connected to a nozzle 414, the other end of the nozzle 414 passes through the pressing plate 409, the inner walls of the conduit 415 and the connecting pipe 416 are both provided with a first one-way valve, a filter is embedded and installed on the side of the connecting pipe 416 away from the mounting cylinder 410, the surface of the conduit 415 is connected to an exhaust pipe, a second one-way valve is provided inside the exhaust pipe, the cross section of the electromagnet 413 is annular, and the nozzle 414 is coaxially arranged with the adjacent electromagnet 413;

[0027] Specifically, the first one-way valve located inside the connecting pipe 416 can allow the outside air to be introduced into the temporary storage chamber through the connecting pipe 416 in one direction, the first one-way valve located inside the conduit 415 can allow the air inside the temporary storage chamber to be discharged in one direction through the conduit 415 and the nozzle 414, and the second one-way valve can allow the gas in the conduit 415 to be discharged in one direction through the exhaust pipe;

[0028] When the electromagnet 413 contacts the lawn mower blade, the second electric push rod 405 continues to move down for a distance. Due to the obstruction of the lawn mower blade, the mounting plate 407 can be driven close to the pressure plate 409, so that the connecting rod 411 is inserted into the interior of the mounting cylinder 410 and the spring 412 is compressed. Since the connecting rod 411 is inserted into the interior of the mounting cylinder 410, the connecting rod 411 pushes the sealing plate to move up along the inner wall of the mounting cylinder 410, thereby increasing the internal space of the temporary storage chamber, so that the internal space forms a negative pressure and the outside air passes through the filter under the action of the pressure difference. The first one-way valve enters the temporary storage chamber for storage. When the second electric push rod 405 drives the mounting plate 407 and the pressure plate 409 to reset, the connecting rod 411 can be driven to reset under the action of the spring 412. At this time, the internal gas stored in the temporary storage chamber can be squeezed and discharged through the first one-way valve in the conduit 415. If the electromagnet 413 contacts the blade of the weeder at this time, the weeder blade blocks the electromagnet 413, so that the gas cannot be discharged normally through the nozzle 414. Therefore, the gas inside the conduit 415 can be discharged through the exhaust pipe under the action of the second one-way valve.

[0029] If the electromagnet 413 is not in contact with the lawn mower blade at this time, the nozzle 414 can be connected to the outside, so that the gas inside the exhaust duct 415 can be discharged directly through the nozzle 414, and the sandblasting remaining on the surface of the placed lawn mower blade can be blown away, reducing the situation where gravel remains on the surface of the lawn mower blade, and the gravel cleaned by the airflow can be introduced into the internal storage of the recovery chamber through the through groove for easy reuse. At the same time, under the action of the baffle 102, the situation of gravel splashing everywhere can be reduced, and the gravel remaining on the surface of the lawn mower blade can be effectively recovered, avoiding the situation where a large amount of gravel remains on the surface of the lawn mower blade after the traditional equipment is processed and is inconvenient to clean.

[0030] Working principle: the unprocessed weeder blade is placed on the placement table 2 through the discharge rod 3 on the left, and the mounting plate 407 can be driven downward by starting the second electric push rod 405. In this process, the pressure plate 409 can be driven to move downward synchronously under the action of the spring 412 and gravity, and the electromagnet 413 is energized until the electromagnet 413 contacts the surface of the weeder blade and can adsorb the weeder blade under the action of magnetic force, and drive it to move upward through the second electric push rod 405. Under the action of the second motor 402, the rotating rod 403 rotates to adjust the position of the two connecting frames 404, so that the unprocessed weeder blade moves to the top of the discharge table 203, and the processed weeder blade is transferred to the top of another discharge rod 3, and the mounting plate 4 is driven by the second electric push rod 405. 07At this time, the electromagnet 413 is powered off, and the effect of transferring the lawn mower blade can be achieved. After the transfer is completed, the second electric push rod 405 drives the mounting plate 407 to reset, and at the same time, the second motor 402 drives the rotating rod 403 to reset the connecting frame 404 for reuse. In this process, the air flow can be sprayed out through the first one-way valve, the second one-way valve, the exhaust pipe, the connecting pipe 416, the conduit 415 and the nozzle 414 to act on the treated surface of the lawn mower blade. The gravel cleaned by the air flow can be introduced into the internal storage of the recovery chamber through the through groove for reuse. At the same time, under the action of the baffle 102, the situation of gravel splashing everywhere can be reduced, and the gravel remaining on the surface of the lawn mower blade can be effectively recovered, avoiding the situation where a large amount of gravel remains on the surface of the lawn mower blade after processing by traditional equipment and is inconvenient to clean.

The specific models can be selected according to actual needs. At the same time, the sandblasting machine 1, the first electric push rod 101, the first motor 204, the second motor 402, the second electric push rod 405 and the electromagnet 413 can be powered by a built-in power supply or by AC power.
