[0031] Example 1

[0032] Refer to the instruction manual Figure 1-5 , a conveying device for transferring stone materials, including a conveying device, the conveying device can be a belt conveyor or an auger conveyor 14, in the present application, the conveying device uses an auger conveyor 14 to convey the stone materials, compared with the belt conveyor, the auger conveyor 14 will not slip when conveying the stone materials, affecting the conveying effect, and a sorting feeding structure is arranged above the conveying device;

[0033] The sorting feeding structure includes a supporting shell 1 arranged above the conveying device, a rolling screen drum 2 is rotatably connected inside the supporting shell 1, a threaded material guide plate 3 is fixedly installed on the inner wall of the rolling screen drum 2, and the rolling screen drum 2 is driven by a driving device. The driving device can drive the rolling screen drum 2 by using a driving motor and a driving belt. With reference to the rolling stirring barrel and other devices, the rolling stirring barrel is driven to rotate by the driving motor and the belt sleeved on the rolling screen drum 2. A plurality of discharge holes 4 are opened inside the rolling screen drum 2, and the rolling screen drum 2 is located above the feeding port of the conveying device;

[0034] When in use, stones are put into the rolling screen drum 2, and the rolling screen drum 2 is driven to rotate by a driving motor. The stones roll inside the rolling screen drum 2, and the stones that meet the standards fall downward through the discharge hole 4 to the feed port of the auger conveyor 14, and the auger conveyor 14 conveys the stones that pass through the rolling screen drum 2 to a designated location; the stones that do not pass through the discharge hole 4 roll inside the rolling screen drum 2, and after being guided by the threaded guide plate 3, the stones that do not pass through the discharge hole 4 are pushed out from the rolling screen drum 2 to a designated place, and then they can be reprocessed to meet the standards.

[0035] A feeding structure for conveying stones into the rolling screen drum 2 is arranged inside the supporting shell 1; the feeding structure includes a guide trough 5 fixedly mounted on the upper end surface of the supporting shell 1, a driving shaft 6 rotatably connected to the supporting shell 1 is arranged below the guide trough 5, a spiral pushing plate 7 is fixedly connected to the driving shaft 6, and a driving motor 8 is fixedly connected to one end of the driving shaft 6. The driving motor 8 is connected to an external power supply. When in use, the driving motor 8 drives the driving shaft 6 to rotate, and the spiral pushing plate 7 is driven to rotate through the driving shaft 6 to push the stones into the rolling screen drum 2.

[0036] The rolling screen drum 2 is fixedly connected to the driving shaft 6 . When the rolling screen drum 2 rotates, the rolling screen drum 2 is synchronously driven to rotate, so that the stones entering the rolling screen drum 2 are screened.

[0037] The cross section of the guide trough 5 is arranged to be an equilateral trapezoidal structure which is narrow at the bottom and wide at the top.

[0038] An anti-blocking push plate 9 is slidably connected to the inner wall of the material guide trough 5, and a plurality of anti-blocking push teeth 10 are fixedly connected to the side of the anti-blocking push plate 9 close to the inside of the material guide trough 5. A stretching elastic member is connected between the anti-blocking push plate 9 and the material guide trough 5. The stretching elastic member adopts a stretching spring. When in use, the anti-blocking push plate 9 is pulled downward by the stretching spring, and a pushing structure for pushing the anti-blocking push plate 9 to slide is provided inside the supporting shell 1.

[0039] The pushing structure includes a pushing cam 11 fixedly connected to the driving shaft 6, an intermediate pushing member 12 is slidably connected inside the supporting housing 1 and abuts against the pushing cam 11, and a connecting rod 13 is connected between the intermediate pushing member 12 and the anti-blocking pushing plate 9;

[0040] During use, when the driving shaft 6 rotates, the driving shaft 6 drives the pushing cam 11 to rotate. When the pushing cam 11 rotates, after the highest point contacts the intermediate pushing member 12, the intermediate pushing member 12 is pushed in the direction away from the supporting shell 1, thereby pushing the anti-blocking pushing plate 9 in the direction away from the supporting shell 1 through the intermediate pushing member 12 and the connecting rod 13; when the highest point of the pushing cam 11 is out of contact with the intermediate pushing member 12, the anti-blocking pushing plate 9 is pulled downward under the action of the tension spring; in this reciprocating manner, multiple large stones that are simultaneously blocked in the material guide trough 5 are pushed upward, thereby preventing the large stones from blocking the material guide trough 5.

[0041] The conveying device adopts an auger conveyor 14 , and an auger support frame 15 is detachably connected below the auger conveyor 14 . The auger support frame 15 can be replaced with auger support frames 15 of different heights according to the height to which the auger conveyor 14 needs to be lifted.

[0042] One end of the supporting shell 1 is rotatably connected to the upper end surface of the auger conveyor 14 , and an angle adjustment structure is installed between the other end of the supporting shell 1 and the auger conveyor 14 .

[0043] The angle adjustment structure includes a support block 16 slidably connected to one end of the auger conveyor 14 , the support block 16 is threadedly connected to a threaded rod 17 rotatably connected to the auger conveyor 14 , and a support rod 18 is connected between the support block 16 and the support housing 1 .

[0044] During use, if it is necessary to transport stones to a higher place, replace the appropriate auger support frame 15. At this time, it is necessary to adjust the angle of the support shell 1 simultaneously, rotate the threaded rod 17, and under the action of the support block 16 and the support rod 18, adjust the support shell 1 to a horizontal state. At this time, the stones inside the rolling screen drum 2 will not fall from the inside of the rolling screen drum 2 under the action of gravity due to angle problems.

[0045] Shielding plates 19 are fixedly connected on both sides of the support shell 1. When in use, the shielding plates 19 shield both sides of the support shell 1 to prevent a large gap from existing between the support shell 1 and the auger support frame 15 after the support shell 1 adjusts its angle, causing stones to splash out from between the support shell 1 and the auger support frame 15.

[0046] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
