Description

Technical Field

[0001] The utility model relates to the technical field of screening feeding, in particular to a feeding device for a lobster grade screening machine. Background Technique

[0002] A drum sieve is a common screening device, and its working principle is to screen materials by rotating a sieve tube. There are multiple sieve holes inside the sieve tube. The materials keep rolling inside the sieve tube. Smaller particles will pass through the sieve holes and be screened out, while larger particles will be blocked by the sieve holes and cannot pass through. The screening efficiency of the drum sieve is high, and it can efficiently complete the screening work of a large amount of materials.

[0003] In the production process of cooked lobster products, it is necessary to grade their sizes. When grading lobsters, a drum-type screening machine is usually used to divide lobsters into three grades according to their sizes. However, during the conveying process, the grading effect is easily affected by the conveying volume. When the conveying volume is large, a large amount of feeding causes the screening machine to screen untimely, and some incompletely screened lobsters are also output, resulting in uneven grade specifications. Therefore, we propose a feeding device for a lobster grade screening machine to solve the above problems. Content of the Utility Model

[0023] Please refer to Figures 1-5 , the present utility model discloses a feeding device for a lobster grading and screening machine, including a storage bin 1 and a blanking pipe 3 installed at its lower end, and further including two groups of adjusting assemblies 4 symmetrically arranged on the blanking pipe 3. The two groups of adjusting assemblies 4 are used to adjust the blanking amount in the blanking pipe 3 to make the blanking uniform. A switch assembly 6 is arranged inside the lower end of the blanking pipe 3. The switch assembly 6 is used to control the discharging of the blanking pipe 3. The blanking pipe 3 extends into a drum type screening machine. A vibration motor 7 is arranged on one side of the storage bin 1 to control the smooth blanking of the storage bin 1. The storage bin 1 is connected to a feed conveying device.

[0024] Specifically, a bin cover 2 is hinged to the upper end of the storage bin 1, and a feed inlet 9 is opened on one side of the storage bin 1. The feed conveying device extends into the feed inlet 9.

[0025] In this implementation scheme, through the setting of the box cover 2, it is convenient to clean the inside of the storage bin 1, and the feeding and conveying device conveys the lobsters from the feeding port 9 to the storage bin 1.

[0026] Specifically, the adjusting assembly 4 includes a driving structure and an adjusting plate 407. A shield 5 is arranged outside the driving structure and the adjusting plate 407. The shield 5 is sleeved and installed on the blanking pipe 3. The driving structure is arranged on the side wall of the blanking pipe 3. The adjusting plate 407 extends into the blanking pipe 3, and a section of the adjusting plate 407 inside the blanking pipe 3 is bent downward.

[0027] In this implementation scheme, through the operation of the driving structure, the adjusting plate 407 is driven to move. When the two adjusting plates 407 move, the blanking amount can be adjusted to control uniform blanking, so that the feeding of the drum sieve is uniform, and thus the screening specifications are neat. Through the downward-bent setting of the adjusting plate 407, it is convenient for blanking.

[0028] Specifically, the driving structure includes a first motor 401. The first motor 401 is a bidirectional motor. Connecting rods 402 are respectively connected to both ends of the first motor 401. Rotating wheels 403 are respectively installed at the relatively far ends of the two connecting rods 402. The rotating wheels 403 are meshed with a rack 405. The rack 405 is connected to an installation groove 406. The installation groove 406 is opened at the bottom of the adjusting plate 407. The adjusting plate 407 is connected through a connection groove 408. The connection groove 408 is opened on the side wall of the blanking pipe 3. A connecting frame 404 is installed on the outer side wall of the blanking pipe 3 below the adjusting plate 407. The first motor 401 is installed on the connecting frame 404.

[0029] In this implementation scheme, the first motor 401 is welded and installed on the connecting frame 404. The connecting frame 404 is welded and installed on the blanking pipe 3. The rack 405 is welded and installed in the installation groove 406. When the first motor 401 operates, it drives the two connecting rods 402 to rotate, thereby driving the two rotating wheels 403 to rotate, which are meshed with the rack 405 to drive the adjusting plate 407 to slide in the connection groove 408, so as to adjust the blanking amount.

[0030] Specifically, the switch assembly 6 includes a second motor 601. The second motor 601 is installed at one end of the side wall of the blanking pipe 3 close to the drum sieve. The output end of the second motor 601 is connected to a rotating plate 602. The rotating plate 602 is movably arranged inside the blanking pipe 3. A magnetic attraction structure is arranged between the lower end of the rotating plate 602 and the inner bottom of the blanking pipe 3. The magnetic attraction structure includes two magnetic strips 603. The two magnetic strips 603 are respectively below the side of the rotating plate 602 away from the drum sieve and at the inner bottom of the blanking pipe 3.

[0031] In this embodiment, the second motor 601 is installed on the blanking pipe 3 by screws. Two magnetic strips 603 are respectively pasted and installed under the side of the rotating plate 602 away from the drum sieve and at the inner bottom of the blanking pipe 3, and are used to rotate the rotating plate 602 and close the blanking pipe 3 when there is no blanking. The two magnetic strips 603 are used to limit the rotating plate 602.

[0032] Specifically, the vibration motor 7 is installed on the mounting frame 8, and the mounting frame 8 is welded and installed on the side wall of the storage bin 1.

[0033] In this embodiment, the vibration motor 7 is installed on the mounting frame 8 by screws, and the storage bin 1 is driven to vibrate by the vibration motor 7, so as to facilitate blanking and prevent blockage.

[0034] The working principle and usage process of the present utility model: When in use, the feeding and conveying device conveys the lobsters from the feeding port 9 to the inside of the storage bin 1, and they fall into the blanking pipe 3 through the gap between the two adjusting plates 407, and are conveyed from the lower end of the blanking pipe 3 to the drum sieve. The feeding is uniform, which is convenient for sieving, improves the sieving effect, and the sieving specifications are neat. When it is necessary to adjust the blanking amount, the first motor 401 is controlled to operate, driving the two connecting rods 402 to rotate, thereby driving the two rotating wheels 403 to rotate, engaging with the rack 405, and driving the adjusting plate 407 to slide in the connecting groove 408, so as to adjust the blanking amount. When there is no need for blanking, the second motor 601 drives the rotating plate 602 to rotate, so that the two magnetic strips 603 are magnetically connected to limit the rotating plate 602, thereby stopping blanking.

[0035] In summary, for the feeding device of the lobster grading sieve machine, the first motor 401, the rotating wheel 403 and the rack 405 are used in cooperation to control the movement of the adjusting plate 407. The two adjusting plates 407 move, so as to adjust the gap between the two adjusting plates 407 and adjust the blanking amount, so that the feeding of the drum sieve is uniform, which is convenient for sieving and makes the sieving specifications neat. The second motor 601, the rotating plate 602 and the magnetic strip 603 are provided to control the opening and closing of the blanking pipe 3 according to whether blanking is needed, avoiding excessive accumulation of materials inside the drum sieve and affecting the sieving effect.
