[0003] When using the existing feed conveying device to quantitatively convey and feed materials, if there are agglomerated material masses in the materials, the feed conveying device cannot process the material masses, and the material masses in the materials directly enter the feed conveying device, which is likely to cause material blockage. When quantitatively weighing the conveyed materials, some materials may adhere to the inner wall of the weighing and metering device, resulting in inaccurate quantitative weighing. The above situations are not conducive to the smooth progress of feed production.

The material masses in the materials can be broken up by the crushing mechanism on the feed hopper, and the materials after eliminating the material masses are conveyed again. The material has good flowability, which is conducive to controlling the balance and stability of the conveyed material flow, avoiding material blockage during the conveying process. At the same time, when it is necessary to maintain and replace the filter structure filter plate in the crushing mechanism on the feed hopper, the filter plate is convenient to maintain and replace. When quantitatively weighing the conveyed materials, the inner wall of the weighing hopper can be cleaned by the material cleaning mechanism inside the weighing hopper, avoiding materials adhering to the inner wall of the weighing hopper. When discharging, the materials can be discharged completely, achieving the cleanest discharging to the greatest extent, ensuring the accuracy of quantitative weighing. Using the feed conveying device of the utility model is conducive to the smooth progress of feed production and product quality control.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the attached Figures 1-5 , the present invention provides the following technical solutions:

[0030] A feed conveying device includes a mounting base 1, a support frame 2, a controller 3, a conveying cylinder 4, a conveying motor 5, a screw rod 6, a feed hopper 7, a filter plate 8 and a crushing mechanism. A support frame 2 is vertically fixed on the upper surface of the mounting base 1. The mounting base 1 can be a concrete mounting base or a steel structure mounting base, etc. A controller 3 is installed at the front end of the support frame 2. The controller 3 is connected to the conveying motor 5, the first motor 11, the weight sensor inside the weighing rack 16, the second motor 18, the first electric telescopic rod 21 and the second electric telescopic rod 23.

[0031] The conveying cylinder 4 is fixed on the support frame 2, and a conveying motor 5 is installed on the outer side surface of the top end of the conveying cylinder 4. The output end of the conveying motor 5 is fixed with a screw rod 6. A spiral conveying blade is arranged on the screw rod 6. The screw rod 6 can perform spiral conveying on the material. The bottom end of the conveying cylinder 4 is fixed with a feed hopper 7. A filter plate 8 is arranged inside the feed hopper 7. Feed materials (such as feed additives, etc.) are put into the inside of the feed hopper 7 and enter the inside of the conveying cylinder 4 after being filtered by the filter plate 8. The conveying motor 5 drives the screw rod 6 to rotate, and the material is conveyed upward through the rotation of the screw rod 6.

[0032] A crushing mechanism is provided on the feed hopper 7. The crushing mechanism includes a support roller 9, a mounting frame 10, a first motor 11, a first rotating rod 12, a first cleaning plate 13 and a crushing piece 14. The rear side of the feed hopper 7 is fixed with the support roller 9, and the mounting frame 10 is snap-fitted inside the support roller 9. The end of the mounting frame 10 is fixed with the first motor 11, and the output end of the first motor 11 is fixed with the first rotating rod 12. The bottom end of the first rotating rod 12 is fixed with the first cleaning plate 13, and a crushing piece 14 is arranged above the first cleaning plate 13. The lower surface of the first cleaning plate 13 is attached to the upper surface of the filter plate 8, and the vertical center line of the first rotating rod 12 coincides with the vertical center line of the feed hopper 7.

[0033] When there are agglomerated masses in the material, the material is put into the feed hopper 7. The first motor 11 inside the crushing mechanism is started. The first motor 11 drives the first rotating rod 12, the first cleaning plate 13 and the crushing piece 14 to rotate. The masses in the material are broken up by the rotation of the crushing piece 14. After the masses are eliminated, the flowability of the material is good, which is beneficial to controlling the balance and stability of the conveying material flow and avoiding material blockage during the conveying process. The material without masses can enter the conveying cylinder 4 through the filter screen holes on the filter plate 8. The filter surface of the filter plate 8 is cleaned by the rotation of the first cleaning plate 13, which can prevent the filter plate 8 from being blocked. The conveying motor 5 rotates to drive the screw rod 6 to rotate, and the material entering the conveying cylinder 4 is conveyed by the screw rod 6 and discharged from the discharge pipe 15.

[0034] The filter plate 8 can be installed in the feed hopper 7 by means of snap-fitting or threaded connection, that is, the filter plate 8 is detachably installed in the feed hopper 7. When the filter plate 8 needs to be maintained and replaced, since the mounting frame 10 is snap-fitted inside the support roller 9, the mounting frame 10 is pulled out from the inside of the support roller 9, so that the first rotating rod 12, the first cleaning plate 13 and the crushing piece 14 are taken out from the inside of the feed hopper 7. Then the filter plate 8 is rotated and removed from the feed hopper 7 for maintenance and replacement.

[0035] The utility model can process the masses in the material. The masses in the material can be broken up by the crushing mechanism on the feed hopper 7. After the masses are eliminated, the flowability of the material is good, which is beneficial to controlling the balance and stability of the conveying material flow and avoiding material blockage during the conveying process. At the same time, when the filter structure, i.e., the filter plate 8, in the crushing mechanism on the feed hopper 7 needs to be maintained and replaced, the filter plate 8 is convenient to maintain and replace.

[0036] A discharge pipe 15 is fixed to the top end of the conveying cylinder 4. The bottom end of the discharge pipe 15 penetrates through the top end of the weighing hopper 17. Materials are discharged from the discharge pipe 15 and flow into the weighing hopper 17. The feed in the weighing hopper 17 is weighed by a weighing frame 16 arranged below the conveying cylinder 4. A weight sensor is installed inside the weighing frame 16. When the weight of the materials inside the weighing hopper 17 reaches the required weight, the weight sensor transmits a signal to the controller 3. The controller 3 controls the conveying motor 5 to stop, so as to stop feeding materials into the inside of the weighing hopper 17. Then, the first electric telescopic rod 21 is opened. Under the action of the first electric telescopic rod 21, the baffle 22 leaves the discharge port opened at the bottom end of the weighing hopper 17, and the materials flow out from the inside of the weighing hopper 17. The weight sensor inside the weighing frame 16 monitors the weight inside the weighing hopper 17 in real time. When the materials inside the weighing hopper 17 are not completely unloaded, the second motor 18 inside the material cleaning mechanism is started. The second motor 18 drives the second rotating rod 19 and the second cleaning plate 20 to rotate. The inner wall of the weighing hopper 17 is cleaned through the rotation of the second cleaning plate 20, so as to prevent materials from adhering to the inner wall of the weighing hopper 17. In this way, the materials can be completely discharged during discharging, ensuring the accuracy of weighing and metering.

[0037] When quantitatively weighing the conveyed materials, the inner wall of the weighing hopper 17 can be cleaned in time through the material cleaning mechanism inside the weighing hopper 17, so as to prevent materials from adhering to the inner wall of the weighing hopper 17, ensuring the accuracy of quantitative weighing.

[0038] Furthermore, the following improvement scheme can also be adopted: As Figure 1 and Figure 2 shown, a second electric telescopic rod 23 is fixed to the outer side surface of the second motor 18. A chute for the movement of the second rotating rod 19 is opened in the middle of the top end of the weighing hopper 17. The second motor 18 is moved under the action of the second electric telescopic rod 23. The second rotating rod 19 moves in the chute at the top end of the weighing hopper 17, and the second cleaning plate 20 is moved. The part of the second cleaning plate 20 that fits the inner wall of the weighing hopper 17 is a brush. When the second motor 18 and the second rotating rod 19 move, the brush on the second cleaning plate 20 is squeezed. Then, the second rotating rod 19 and the second cleaning plate 20 are rotated under the action of the second motor 18, so that the second cleaning plate 20 does not fit the inner wall of the weighing hopper 17, and the brush on the second cleaning plate 20 unfolds. The second motor 18 is opened again, and the second motor 18 drives the second cleaning plate 20 to rotate within a small range, thereby shaking the brush on the second cleaning plate 20 to shake off the materials adhering to the second cleaning plate 20, achieving the cleanest discharging to the greatest extent.

[0039] Using the feed conveying device of the present utility model is beneficial to the smooth progress of feed production and product quality control.
