[0029] It should be noted here that: in the process of conveying quartz sand by rotating the spiral blades 103, when some foreign matter is mixed in the quartz sand and is stuck between the spiral blades 103 and the inner wall of the body 101, the two groups of spiral blades 103 are driven to move away from each other in the axial direction of the driving rod 102 through transmission, so that the foreign matter that is against the inner wall of the body 101 between the spiral blades 103 is separated under the action of the axial friction force, thereby reducing the probability of poor rotation and jamming of the spiral blades 103 during the conveying process, further reducing the probability of tearing and damage of the spiral blades 103, and facilitating the screw conveyor to stably and continuously convey the quartz sand. In the process of the two groups of spiral blades 103 moving away from each other, the pitch between the two groups of spiral blades 103 on the rod body 1021 is increased, thereby further increasing the material discharge and conveying capacity of the rod body 1021, and alleviating the blockage of material conveying inside the body 101.

[0030] Preferably, there are multiple transmission assemblies, and the multiple transmission assemblies are arranged in a ring array between the sleeve 6 and the mounting cylinder 7;

[0033] It should be noted here that: during the rotation of the sleeve 6, the second spring 1104 between the fixed plate 1001 and the mounting plate 1002 drives the mounting cylinder 7 to rotate, and when the rotation of the spiral blade 103 outside the mounting cylinder 7 is blocked, as the rod body 1021 and the sleeve 6 continue to be driven, the fixed plate 1001 moves toward the mounting plate 1002 to shrink, and during the movement, the sliding rod 1103 is pushed to slide on the sleeve 1102, and at this time, the mounting cylinder 7 and the sleeve 6 rotate relative to each other, so as to judge whether the rotation of the mounting cylinder 7 and the spiral blade 103 is blocked;

[0034] It is worth noting here that the sliding rod 1103 and the sleeve 1102 facilitate stable contraction transmission between the fixing plate 1001 and the mounting plate 1002 .

[0035] Preferably, the pushing assembly includes two groups of transmission plates 1201 symmetrically fixed inside the annular mounting cavity 5, the two groups of transmission plates 1201 are respectively fixed to the inside of the two groups of mounting cylinders 7, a transmission pin 1202 is fixed to one side of the two groups of transmission plates 1201, a push plate 1203 is fixed to the rod body 1021, the push plate 1203 is arranged inside the annular mounting cavity 5 and between the two groups of sleeves 6, and two groups of inclined surfaces 1204 for driving against the front end of the transmission pin 1202 are opened on the push plate 1203;

[0036] It should be noted here that: when some foreign matter exists inside the quartz sand and is stuck between the spiral blade 103 and the inner wall of the body 101, the rotation of the spiral blade 103 is hindered, and as the driving motor 104 continues to drive the rod body 1021 and the sleeve 6, the fixed plate 1001 contracts toward the mounting plate 1002. In the process of the fixed plate 1001 moving toward the mounting plate 1002, the push plate 1203 is driven by the rod body 1021 to move toward the transmission plate 1201. In the process of movement, the two groups of inclined surfaces 1204 on the push plate 1203 respectively abut against the transmission pins 1202 on the two groups of transmission plates 1201. In the process of abutting, the two groups of transmission plates 1201 are pushed to move away from each other.

[0037] Preferably, the connecting assembly includes a plurality of groups of slide grooves 901 provided inside the annular mounting cavity 5, and each group of slide grooves 901 is arranged in an annular array state, each group of slide grooves 901 is slidably connected with a transmission slider 902, and each group of transmission sliders 902 is fixed to the inner wall of the sleeve 6;

[0038] It should be noted here that: through multiple sets of slide grooves 901 and sliders 902, it is convenient to drive the sleeve 6 to rotate synchronously during the rotation of the rod body 1021, and through multiple sets of slide grooves 901 and sliders 902, it is convenient to adjust the movement of the sleeve 6 on the rod body 1021, and in the process of movement of the sleeve 6, the fixing plate 1001, the mounting plate 1002 and the components on the identification component can drive the installation tube 7 to move, so that the installation tube 7 can be moved in the axial direction of the rod body 1021 while rotating.

[0039] Preferably, an accordion cover 8 for isolating the annular installation cavity 5 from the outside is connected between the two groups of installation tubes 7 and between the installation tubes 7 and the end of the rod body 1021;

[0040] It should be noted here that the interior of the annular installation cavity 5 is sealed by the accordion cover 8 to prevent the components inside the annular installation cavity 5 from being affected.

[0041] Preferably, the filter assembly includes two sets of mounting rollers 201 rotatably connected to the feed frame 105, a filter belt 202 for filtering particulate foreign matter on the feed is connected between the two sets of mounting rollers 201, and a mounting motor 203 for driving the mounting rollers 201 is installed on the outer side of the feed frame 105;

[0042] It should be noted here that: during the process of feeding the interior of the body 101 through the feed frame 105, the material passes through the filter belt 202, and the feed is filtered by the filter belt 202 to prevent the material from being mixed with larger foreign objects that affect the normal transportation of the screw conveyor. During the filtering process of the filter belt 202, the installation roller 201 is driven to rotate by the installation motor 203. During the rotation of the installation roller 201, the filter belt 202 is driven to move between the two groups of installation rollers 201. Through the movement of the filter belt 202, it is convenient to use different positions on the filter belt 202 to filter the feed, thereby ensuring the filtering transparency effect.

[0043] Preferably, the guide collection assembly includes a slot 301 opened on one side of the feed frame 105 and communicating with the inside of the feed frame 105, a guide scraper 302 is arranged obliquely inside the slot 301, the front end of the guide scraper 302 is arranged against the outside of the filter belt 202, a strip plate 303 is fixed to one end of the guide scraper 302 away from the filter belt 202, and an elastic component for elastically pushing the strip plate 303 is arranged between the strip plate 303 and the feed frame 105;

[0044] It should be noted here that: during the movement of the filter belt 202, the elastic component pushes the strip plate 303, so that the material guide scraper 302 on the strip plate 303 remains against the outer side of the filter belt 202. Through the abutment between the material guide scraper 302 and the outer side of the filter belt 202, foreign matter remaining on the filter belt 202 after filtering is guided outward through the material guide scraper 302, thereby facilitating the continuous filtering operation of the filter belt 202.

[0045] Preferably, the elastic component includes a plurality of fixed blocks 401 fixed at the lower end of the strip plate 303, a T-shaped rod 402 is slidably connected to the fixed block 401, one end of the T-shaped rod 402 is fixed to the outer side of the feed frame 105, a first spring 403 is sleeved on the outer side of the T-shaped rod 402, and both ends of the first spring 403 are respectively connected to the other end of the T-shaped rod 402 away from the feed frame 105 and the fixed block 401;

[0046] It should be noted here that: the movement of the strip plate 303 and the material guide scraper 302 is guided by multiple sets of fixed blocks 401 and T-shaped rods 402, and the elastic force of the first spring 403 on the fixed block 401 is used to push the material guide scraper 302 on the strip plate 303 to maintain contact with the outer side of the filter belt 202, thereby ensuring the effect of separating and guiding materials.

[0047] In this scheme: a conveying device for quartz sand processing comprises the following steps:

[0048] In the process of conveying quartz stone by using the screw conveyor, the quartz sand to be conveyed is put into the interior of the machine body 101 through the feeding frame 105. During the putting process, the driving rod 102 is driven to rotate by the driving motor 104. Since the driving rod 102 is composed of multiple groups of rod bodies 1021 spliced ​​by bolts, during the rotation of the driving rod 102, each group of rod bodies 1021 is driven to rotate. During the rotation of the rod body 1021, the connection transmission of multiple groups of slide grooves 901 and sliders 902 drives the two groups of sleeves 6 to rotate. During the rotation of the sleeve 6, the connection transmission action of the second spring 1104 between the fixing plate 1001 and the mounting plate 1002 drives the mounting cylinder 7 to rotate. During the rotation of the mounting cylinder 7, the spiral blade 103 is driven to rotate. Through the rotation of the spiral blade 103, the put-in quartz sand is conveyed;

[0049] In the process of conveying quartz sand by the rotation of the spiral blade 103, when some foreign matter is mixed in the quartz sand and is stuck between the spiral blade 103 and the inner wall of the body 101, the rotation of the spiral blade 103 is hindered, and as the driving motor 104 continues to drive the rod body 1021 and the sleeve 6, the fixed plate 1001 is caused to contract toward the mounting plate 1002. In the process of the fixed plate 1001 moving toward the mounting plate 1002, the push plate 1203 is driven by the rod body 1021 to move toward the transmission plate 1201. In the process of movement, the two groups of inclined surfaces 1204 on the push plate 1203 are respectively abutted against the transmission pins 1202 on the two groups of transmission plates 1201. In the process of abutting against each other, the two groups of transmission plates 1201 are pushed to move away from each other. In the process of the two groups of transmission plates 1201 moving away from each other, The two groups of mounting tubes 7 and the spiral blades 103 outside the two groups of mounting tubes 7 are driven to move away from each other in the axial direction of the driving rod 102. The two groups of spiral blades 103 move away from each other in the axial direction of the driving rod 102, so that the foreign matter abutting against the inner wall of the spiral blades 103 and the body 101 is separated under the action of the axial friction force, thereby reducing the probability of the spiral blades 103 rotating poorly and getting stuck during the conveying process, further reducing the probability of the spiral blades 103 being torn and damaged, and facilitating the screw conveyor to stably and continuously convey the quartz sand. In addition, in the process of the two groups of spiral blades 103 moving away from each other, the pitch between the two groups of spiral blades 103 on the rod body 1021 is increased, further increasing the material discharge and conveying capacity of the rod body 1021, and relieving the blockage of the material conveying inside the body 101;

[0050] During the process of feeding the material into the body 101 through the feeding frame 105, the material passes through the filter belt 202, and the feed is filtered by the filter belt 202 to prevent the material from being mixed with large foreign objects that affect the normal transportation of the screw conveyor. During the filtering process of the filter belt 202, the installation roller 201 is driven to rotate by the installation motor 203. During the rotation of the installation roller 201, the filter belt 202 is driven to move between the two sets of installation rollers 201. Through the movement of the filter belt 202, The feed is filtered at different positions on the filter belt 202 to ensure the filtering transparency. When the filter belt 202 moves, the elastic component pushes the strip plate 303 to keep the material guide scraper 302 on the strip plate 303 against the outside of the filter belt 202. The foreign matter remaining on the filter belt 202 after filtering is guided outward through the material guide scraper 302 through the friction between the material guide scraper 302 and the outside of the filter belt 202, so as to facilitate the continuous filtering operation of the filter belt 202.
