[0029] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0030] Reference Figures 1-10A semi-automatic sand separator includes a frame 1. A tilting sand separator mechanism 2 and a replenishing sand mechanism 3 are movably connected inside the frame 1. A conveying mechanism 4 is installed inside the frame 1 near the replenishing sand mechanism 3. A receiving hopper 5 is placed on the conveying mechanism 4, which is used to convey the receiving hopper 5. The tilting sand separator 2 consists of a drive assembly 21, a conveying assembly 22, a feeding assembly 23, and a hopper body 24. The drive assembly 21 includes a tilting motor 210 installed on one side of the rear surface of the frame 1, a solenoid valve 211 near the tilting motor 210, a drive gear 212 installed at the output end of the tilting motor 210, a driven gear 213 meshing with the outer wall of the drive gear 212, a frame 214 installed at the output end of the driven gear 213, and a frame 214 installed on the output end of the driven gear 213. The frame 214 includes a pilot two-way valve 215 on one side, a lifting cylinder 216 diagonally mounted on one side of the frame 214, a floating connector 217 located at the output end of the lifting cylinder 216, and a guide shaft 218 diagonally mounted on one side of the frame 214. The feeding assembly 23 includes a funnel 230, a pneumatic vibrator 231 mounted on one side of the funnel 230, a connecting connector 232, and a clamp valve 233 mounted at the feeding point of the funnel 230. The conveying assembly 22 includes a geared motor 220 mounted on one side of the frame 214, a chain 221 rotatably connected to the output end of the geared motor 220, and a power roller 222 meshing with the chain 221. The size of the funnel 230 is adapted to the size of the barrel 24.

[0031] With this configuration, the flipping sand-distributing mechanism 2 can rotate the barrel 24 to be directly above the receiving hopper 5 and introduce quartz sand into the receiving hopper 5. The barrel 24 is filled with quartz sand and is limited by the feeding component 23 and the conveying component 22. Thus, the drive component 21 can flip the barrel 24 as a whole to be above the receiving hopper 5. After a certain weight of quartz sand in the barrel 24 is quantitatively distributed into multiple receiving hoppers 5, the drive component 21 drives the barrel 24 to return to its original position, removes the empty barrel 24 from the conveying component 22, and uses a transport vehicle to place another barrel 24 filled with quartz sand on the conveying component 22, realizing the feeding and unloading of the barrel 24, which is convenient to use.

[0032] The sand replenishment mechanism 3 includes a rotary cylinder 31 installed inside the frame 1, a replenishment component 32 rotatably connected to the output end of the rotary cylinder 31, a first fixed plate 33 and a second fixed plate 34 installed on both sides of the replenishment component 32, a first lifting cylinder 35 and a second lifting cylinder 36 installed on the first fixed plate 33 and the second fixed plate 34, a lifting pipe 37 installed at the output end of the first lifting cylinder 35, a lifting plate 38 fixed below the lifting pipe 37, and a connecting pipe 39 movably connected inside the lifting pipe 37. The inner diameter of the connecting pipe 39 is larger than the outer diameter of the lower opening of the feeding component 23. The inner diameter of pipe 37 is larger than the outer diameter of connecting pipe 39. The diameter of lifting plate 38 is matched with the diameter of the upper surface of receiving hopper 5. The feeding assembly 32 includes a housing 320 installed at the output end of rotary cylinder 31, a weighing transmitter 321 and a solenoid valve 322 installed on the inner wall of housing 320, a weighing sensor 323 symmetrically installed on one side of housing 320, a funnel 324 installed on the weighing sensor 323, a pneumatic vibrator 325 installed on one side of funnel 324, and a clamping valve 326 installed at the discharge point of funnel 324.

[0033] With this configuration, when quartz sand is introduced into the receiving hopper 5 via the tilting sand-separating mechanism 2, the lifting cylinder 35 and the lifting cylinder 36 respectively drive the lifting plate 38 to descend and close the receiving hopper 5, and the connecting pipe 39 to rise and connect with the discharge port of the funnel 230. When the weight of the quartz sand introduced into the receiving hopper 5 by the tilting sand-separating mechanism 2 is close to the set target weight, but less than the set target weight, the quartz sand is no longer introduced into the receiving hopper 5 via the tilting sand-separating mechanism 2, and the process is switched to... Funnel 2 324 introduces quartz sand into receiving hopper 5. During the replenishment process, pneumatic vibrator 2 325 vibrates the outer wall of funnel 2 324 to assist in the discharge of quartz sand inside, preventing quartz sand from clogging or remaining at the discharge port below funnel 2 324. The insufficient weight of quartz sand is replenished into receiving hopper 5. That is, the combination of fast feeding by flipping sand distribution mechanism 2 and slow feeding by sand replenishment mechanism 3 achieves quantitative sand distribution into receiving hopper 5, effectively improving the practicality and convenience of the device.

[0034] The conveying mechanism 4 includes a support plate 41 installed on one side of the frame 1, a support frame 42 installed on the support plate 41, two drive rollers 43 rotatably connected to the inner wall of the support frame 42, a conveyor belt 44 rotatably connected to the outer wall of the drive rollers 43, and a drive motor 45 for driving the drive rollers 43 to rotate. A through-beam sensor 46 is installed on the side of the support frame 42 close to the support plate 41, and a reflection sensor 47 is installed on the side of the support frame 42 away from the support plate 41. A weighing sensor 6 is installed below the conveying mechanism 4.

[0035] With this configuration, the size of the receiving hopper 5 is matched with the width of the inner wall of the support frame 42, preventing the receiving hopper 5 from shifting left or right during the conveying process. The support frame 42 acts as a guide. When the receiving hopper 5 needs to be conveyed to a certain position, the drive motor 45 is started to drive the power roller 43 to rotate through the external synchronous belt. The rotation of the power roller 43 drives the conveyor belt 44 to rotate, placing the receiving hopper 5 on the conveyor belt 44 for conveying. When it is detected by the reflection sensor 47, an electrical signal is transmitted to the controller 7. The controller 7 controls the drive motor 45 to shut down, thereby realizing the conveying of the receiving hopper 5 and bringing it to the designated position for use.

[0036] A controller 7 is installed on one side of the frame 1. The flipping sand-distributing mechanism 2, the sand-replenishing mechanism 3, and the conveying mechanism 4 are all electrically connected to the controller 7. The lower surface of the frame 1 is equipped with feet 8 in a rectangular array.

[0037] With this setup, the controller 7 enables the automated operation of multiple components on the device, and the multiple grounding feet 8 improve the stability of the device.

[0038] Working principle: The barrel 24 is placed on the power roller 222 by a transport vehicle, so that its upper surface abuts against the lower surface of the funnel 230. The lifting cylinder 216 is activated, which drives the floating joint 217 to descend and moves the guide shaft 218. The floating joint 217 abuts against the corresponding sleeve, thereby limiting the barrel 24 to the lower surface of the power roller 222 and the funnel 230, fixing the position of the barrel 24. The tilting motor 210 is activated, which drives the drive gear 212 to rotate. Wheel 212 rotates and meshes with driven gear 213, causing driven gear 213 to rotate. Since frame 214 is mounted on driven gear 213, the rotation of driven gear 213 causes frame 214 to flip directly above sand replenishment mechanism 3. In the initial state, the position of connecting pipe 39 corresponds to the position of the discharge port of funnel one 230. When sand needs to be added to funnel two 324, the rotary cylinder 31 is activated to rotate funnel two 324 directly below funnel one 230, through the pilot two-way valve. Valve 215 and solenoid valve 211 drive clamp valve 233 and pneumatic vibrator 231 to open, allowing the quartz sand material inside barrel 24 to be introduced into funnel 324 for storage through funnel 230. During the material introduction process, pneumatic vibrator 231 vibrates the outer wall of funnel 230 to assist in material feeding. Simultaneously, weighing sensor 323 monitors the weight of the quartz sand material inside funnel 324 in real time. Weighing sensor 323 is electrically connected to weighing transmitter 321, which can... The electrical signal of the weighing sensor 323 is converted into a standard electrical signal and output to the controller 7. The controller 7 monitors the weight of the material inside the funnel 324 in real time. When the amount of sand added reaches the set weight value, the controller 7 controls the clamp valve 233 to close and stop adding sand to the funnel 324. After adding sand to the funnel 324, the rotary cylinder 31 is driven again to drive the funnel 324 back to the feeding position. At this time, the connecting pipe 39 is aligned with the discharge port of the funnel 230 again.

[0039] When it is necessary to transfer the quartz sand material in the barrel 24 to multiple receiving barrels 5 to achieve the purpose of separating the quartz sand material in the barrel 24, the receiving barrels 5 are placed on the conveying mechanism 4 for conveying. When they are detected by the reflection sensor 47, the conveying mechanism 4 stops conveying. At this time, the receiving barrels 5 are aligned with the lifting plate 38. Simultaneously, the lifting cylinder 1 35 and the lifting cylinder 2 36 are activated. The lifting cylinder 1 35 drives the lifting pipe 37 and the lifting plate 38 to move down, so that the lifting plate 38 closes the upper surface of the receiving barrel 5. The drive pipe 39 moves upward to the outer wall of the lower opening of the funnel 230, so that the drive pipe 39 is aligned with the lower opening of the funnel 230. The controller 7 controls the clamp valve 233 to open through the pilot two-way valve 215 and the solenoid valve 211, allowing the quartz sand material in the barrel 24 to be guided into the receiving hopper 5. The weight of the quartz sand material in the receiving hopper 5 is monitored in real time by the weighing sensor 6. When the weight of the quartz sand material in the receiving hopper 5 approaches the target set weight value, the clamp valve 233 is closed to stop the material from entering the receiving hopper 5. The material is guided by lifting cylinders 35 and 36, which drive the lifting plate 38 to move upward and the connecting pipe 39 to move downward and return to its original position. Then, the rotary cylinder 31 is activated again, driving the funnel 324 to rotate between the receiving hopper 5 and the funnel 230. The controller 7 and solenoid valve 322 then open the clamp valve 326, allowing the quartz sand in the funnel 324 to be fed into the receiving hopper 5 for replenishment. This continues until the weight of the quartz sand in the receiving hopper 5 detected by the weighing sensor 6 matches the set weight value, thus completing the replenishment process. After the material is fed, close the clamp valve 326 and then remove the receiving bucket 5 from the conveying mechanism 4. This device can feed material into the receiving bucket 5 through the flipping sand-distributing mechanism 2, and replenish the receiving bucket 5 with the sand-replenishing mechanism 3. With the cooperation of the two, the quartz sand material in the bucket 24 is quantitatively distributed into multiple receiving buckets 5 to achieve the purpose of sand distribution. The flipping sand-distributing mechanism 2 adopts a fast feeding method, and the sand-replenishing mechanism 3 adopts a slow feeding (replenishing) method, which can achieve quantitative sand distribution and improve the practicality and convenience of the device.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
