The outer sides of the first gear 301 and the second gear 303 are meshed with the inside of the conveying chain 302, the small gear 305 is meshed with the large gear 306, the rotating gear 401 and the outer sides of the docking gear 403 are meshed with the inside of the conveyor belt 402, the first bevel gear 405 is meshed with the second bevel gear 406, the threaded block 308 is connected to the nut of the vertical screw 307, and the moving block 408 is connected to the nut of the horizontal screw 407.

[0020] A partition 102 and a baffle 104 are vertically arranged in the middle of the sand spreading box 1, and the length of the partition 102 is smaller than that of the baffle 104. A support plate 106 is arranged between the bottom end of the partition 102 and the baffle 104, and an inner cavity 103 is arranged at the top of the support plate 106. The first gear 301, the transmission chain 302, the second gear 303, the connecting rod 304, the small gear 305, the large gear 306, the vertical lead screw 307, the threaded block 308 and the lifting rod 309 are all arranged inside the inner cavity 103, and the lifting plate 310 is located at the bottom end of the support plate 106. A storage box 101 is provided on the side of the partition 102 away from the baffle 104, and the stirring rod 203 is arranged inside the storage box 101. A placement cavity 105 is provided on the side of the baffle 104 away from the partition 102, and a rotating rod 404, a first bevel gear 405, a second bevel gear 406, a transverse lead screw 407 and a moving block 408 are all arranged inside the placement cavity 105.

[0021] In this embodiment, it should be noted that: an inlet for filling sand is provided at the top of the storage box 101, and the staff loads sand into the storage box 101 from this position. The sand flows through the storage box 101 to the sand outlet 5, and flows out from the sand outlet 5 and falls on the track.

[0022] To prevent the sand inside the storage box 101 from getting damp and clumping, the start of the drive motor 201 is set through the PLC controller. For example, the drive motor 201 is started 1-2 times per hour, and the sand in the sandbox is stirred for 5-10 minutes each time. The starting frequency of the drive motor 201 can be manually changed during rainy days or rainy and snowy weather in the south.

[0023] The driving motor 201 is started to drive the rotating rod 202 to rotate, so that the multiple groups of stirring rods 203 stir and break up the sand inside the storage box 101 .

[0024] Embodiment 2: Different from the first embodiment, Figure 1-4 as well as Figure 7, this embodiment also has the following further contents: the anti-blocking component 3 is used to dredge the sand at the sand outlet 5 to prevent the sand from piling up at the sieve plate 6. The sieve plate 6 is arranged in the shape of multiple circular holes. A first gear 301 is provided at one end of the rotating rod 202 close to the driving motor 201, a second gear 303 is provided on one side of the first gear 301, a transmission chain 302 is provided outside the first gear 301 and the second gear 303, a connecting rod 304 is provided at the bottom end of the second gear 303, a pinion 305 is provided at one end of the connecting rod 304 away from the second gear 303, a large gear 306 is provided at the side of the small gear 305 away from the first gear 301, a vertical lead screw 307 is provided at the bottom end of the large gear 306, a threaded block 308 is provided on the vertical lead screw 307, a lifting rod 309 is provided at the side of the threaded block 308 away from the vertical lead screw 307, a lifting plate 310 is provided at the bottom end of the lifting rod 309, and a plurality of plug rods 311 are equidistantly provided at the bottom end of the lifting plate 310.

[0025] The number of the insertion rods 311 is consistent with the number of the circular holes on the sieve plate 6 , the tooth marks of the small gear 305 and the large gear 306 are consistent in size, and the diameter of the small gear 305 is smaller than the diameter of the large gear 306 .

[0026] In this embodiment, it should be noted that: when the driving motor 201 is started, the rotating rod 202 and the first gear 301 located on the rotating rod 202 rotate, and the transmission chain 302 connected to the outside of the first gear 301 rotates to drive the second gear 303 to rotate, thereby realizing the rotation of the connecting rod 304 and the small gear 305, and the large gear 306 meshing with the small gear 305 rotates, realizing the rotation of the vertical screw 307, and the threaded block 308 connected to the nut of the vertical screw 307 moves up and down on the vertical screw 307, driving the lifting rod 309 to descend, so that the insertion rod 311 is inserted into the circular hole position of the sieve plate 6, pushing the blocked sand outward to avoid sand blockage.

[0027] Since the diameter of the small gear 305 is smaller than that of the large gear 306, the large gear 306 rotates once only after the small gear 305 rotates several times, so the rotation rod 202 can drive the stirring rod 203 to rotate at a high frequency while the insertion rod 311 rises and falls, so as to fully break up the sand.

[0028] At the same time, pressure sensors are provided on the partition 102 at the upper and lower ends of the threaded block 308. When the insertion rod 311 moves downward, the bottom end of the threaded block 308 is connected to the pressure sensor below the partition 102. At this time, the driving motor 201 rotates in the opposite direction to realize the rising of the insertion rod 311. When the top end of the threaded block 308 is connected to the pressure sensor above the partition 102, the driving motor 201 rotates forward to realize the reciprocating motion of the insertion rod 311.

[0029] Implementation three: Reference Figure 1-4 as well as Figure 7 Compared with the first and second embodiments, in this embodiment: the auxiliary protection component 4 is used to guide the sand at the sand outlet 5, and the auxiliary protection component 4 includes a rotating gear 401, a conveyor belt 402, a docking gear 403, a rotating rod 404, a first bevel gear 405, a second bevel gear 406, a transverse lead screw 407, a moving block 408 and a translation plate 409. The top of the large gear 306 is provided with a rotating gear 401, and the rotating gear 401 is away from the side of the driving motor 201. A docking gear 403 is provided, and a conveyor belt 402 is provided on the outer side of the docking gear 403 and the rotating gear 401, a rotating rod 404 is provided at the bottom end of the docking gear 403, a first bevel gear 405 is provided at the bottom end of the rotating rod 404, a second bevel gear 406 is provided on the side of the first bevel gear 405 away from the rotating rod 404, a transverse screw 407 is provided on the side of the second bevel gear 406 close to the insertion rod 311, a moving block 408 is provided on the transverse screw 407, and a translation plate 409 is connected to the moving block 408.

[0030] The sand outlet 5 is arranged at an angle at the bottom of the sand spreading box 1, and a blocking gauze 7 is provided on the side of the bottom of the storage box 101 away from the sieve plate 6. The blocking gauze 7 is arranged at an angle, and a pull-out placement box 701 is provided at the end of the blocking gauze 7 away from the stirring rod 203, and a silicone ball 702 is provided inside the pull-out placement box 701.

[0031] In this embodiment, it should be noted that: when the large gear 306 rotates, the rotating gear 401 located at the top of the large gear 306 rotates, thereby driving the conveyor belt 402 and the docking gear 403 to rotate, realizing the rotation of the rotating rod 404, and further driving the first bevel gear 405 to rotate, and the second bevel gear 406 meshing with the first bevel gear 405 rotates, realizing the rotation of the transverse screw 407, and the moving block 408 connected to the nut of the transverse screw 407 moves left and right, and the translation plate 409 moves left and right.

[0032] The reciprocating movement of the translation plate 409 guides the flow direction of the sand at the sand outlet 5 on the one hand, and on the other hand, when there is no need to spread sand, the translation plate 409 can seal the sand outlet 5 to prevent the sand from flowing out and avoid the entry of external moisture; a color-changing silicone ball 702 can be placed inside the pull-out placement box 701 to absorb the moisture of the sand inside the storage box 101. When the staff fills the sand, they can observe whether the silicone 702 changes color to replace the silicone ball 702, so that the silicone ball 702 always remains dry.
