Technical Field
[0001] The utility model relates to the technical field of vibration screening machines, in particular to a novel vibration screening machine for automatic dredging of pellet feed. Background Art
[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc. Granular feed is a feed with comprehensive nutrition and strong stability. It is not easy to disintegrate in water, not easy to pollute water bodies, easy to digest and absorb, and farmers save labor and effort. It is deeply favored by the majority of aquaculture farmers. In the process of feed production, in order to ensure the quality of the feed, a vibrating screening machine will be used to screen the feed to screen out feed of different sizes.
[0003] Prior art, such as the patent with announcement number CN212916464U, discloses an automatic diversion vibration screening machine for pellet feed, comprising a shell and a feed feed port, wherein a feed feed port is arranged above the shell, a first slope is arranged below the feed feed port, a first slope baffle is arranged on the first slope, the first slope baffle is connected to a third type of pellet feed baffle, the third type of pellet feed baffle is connected to a second slope, the second slope is connected to a discharge port of the third type of pellet feed, a diversion device is also arranged above the first slope, a vibration screening device is arranged below the first slope baffle, a third slope is arranged below the vibration screening device, and the third slope is connected to the discharge port of the first type of pellet feed, which has the advantages of diversion before screening and not easy to be blocked.
[0004] The above prior art has obvious beneficial effects, but still has shortcomings:
[0005] In the above-mentioned prior art, large-particle feed is conveyed by a drainage roller to improve the efficiency of feed screening. However, in actual use, after the feed is dropped from the feed inlet and falls on the first slope, some large feed will entrain small feed and be discharged from the second slope along the drainage roller without being screened by the screen plate. When the amount of feed screened is large, the feed may also accumulate on one side of the drainage roller and cannot slide down for screening, which affects the screening of the feed and reduces the screening degree of the feed. Therefore, a new vibration screening machine for automatic drainage of granular feed is proposed. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model provides a novel vibration screening machine for automatic flow separation of pellet feed, which is convenient for flow separation of feed to improve screening efficiency and has a high degree of feed screening.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of vibration screening machine for automatic drainage of pellet feed, comprising a shell and a sieve plate installed in the shell, a bracket is installed on the side wall of the shell, a vibration motor is fixedly connected to the bottom surface of the shell, adjustment grooves are opened on both sides of the shell, adjustment units are installed in the two adjustment grooves, a drainage rod is rotatably connected between the two adjustment units, a driving motor is installed on the outer wall of one of the adjustment units, the output shaft of the driving motor is fixedly connected to one end of the drainage rod, a spiral blade is fixedly connected to the outer wall of the drainage rod, a discharge trough corresponding to the conveying direction of the spiral blade is opened on one side of the sieve plate, a discharge hopper that passes through the shell is fixedly connected in the discharge trough, the sieve plate is tilted, a first discharge port is opened on the lower outer wall of the shell near the sieve plate, and a feeding unit is installed on the upper end of the shell.
[0008] Preferably, the adjustment unit includes an adjustment block, which is slidably connected to the adjustment groove, and a screw is fixedly connected to the upper surface of the adjustment block. The upper end of the screw is passed through the outside of the shell and is threadedly connected to a first nut.

[0009] Preferably, the inner bottom surface and top surface of the adjustment groove are both provided with a clearance groove, and the adjustment unit also includes two shielding plates, which are respectively fixedly connected to the bottom surface and the upper end surface of the adjustment block, and the two shielding plates are respectively slidably connected to the two clearance grooves.
[0010] Preferably, the adjusting unit further comprises a second nut, the second nut is threadedly connected to the outer wall of the screw rod, and the second nut is located in the adjusting groove.
[0011] Preferably, a guide inclined plate is fixedly connected to the upper surface of the sieve plate, and the guide inclined plate shields the position obliquely above the discharge chute.
[0012] Preferably, the inner bottom surface of the shell is an inclined structure, and the inclination direction of the inner bottom surface of the shell is opposite to the inclination direction of the screen plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. When the feed needs to be screened, the utility model intercepts the large-particle feed through the diversion rod driven by the motor, and the spiral blades on the outer wall of the diversion rod drive the intercepted large-particle feed to move toward the discharge trough. The small-particle feed contained in the large-particle feed passes through the sieve plate from the bottom of the diversion rod as it is vibrated out for screening. The spiral blade drives the large-particle feed to fall from the discharge trough into the discharge hopper for discharge, so that when the feed is screened, the large-particle feed can be discharged through diversion, thereby improving the screening efficiency. In addition, when the feed is diverted, there will be no accumulation or small-particle feed will be carried out, so that the feed screening is continuous and the screening degree of the feed is improved.

[0017] 3. The utility model can shield the adjustment slot for making way for the adjustment block by setting the adjustment block in the adjustment unit in cooperation with the shielding plates at both ends thereof, so that the feed will not be exposed from the adjustment slot. When the adjustment block is adjusted in height, the shielding plate slides in the making way slot, thereby improving practicality.
[0018] 4. The utility model controls the feed discharging and screening speed by setting a feeding unit with adjustable discharge size, so as to improve the adaptability and screening degree of feed screening.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-5 The new type of vibration screening machine for automatic drainage of pellet feed in this embodiment comprises a shell 1 and a screen plate 2 installed in the shell 1, a bracket 3 is installed on the side wall of the shell 1, a vibration motor 4 is fixedly connected to the bottom surface of the shell 1, adjustment slots 15 are provided on both sides of the shell 1, adjustment units 6 are installed in the two adjustment slots 15, a drainage rod 10 is rotatably connected between the two adjustment units 6, a driving motor 9 is installed on the outer wall of one of the adjustment units 6, the output shaft of the driving motor 9 is fixedly connected to one end of the drainage rod 10, a spiral blade 11 is fixedly connected to the outer wall of the drainage rod 10, a discharge slot 12 corresponding to the conveying direction of the spiral blade 11 is provided on one side of the screen plate 2, a discharge hopper 13 that penetrates to the outside of the shell 1 is fixedly connected in the discharge slot 12, the screen plate 2 is tilted, a first discharge port 7 is provided on the lower end outer wall of the shell 1 near the screen plate 2, and a feeding unit 5 is installed on the upper end of the shell 1.
[0028] like Figure 1-4As shown, the structure of a new type of vibration screening machine for automatic flow of pellet feed in the utility model is similar to that of an existing new type of vibration screening machine for automatic flow of pellet feed, such as a new type of vibration screening machine for automatic flow of pellet feed disclosed in the patent with announcement number CN212916464U. The main improvement of the utility model is that; when the feed needs to be screened, the vibration motor 4 and the drive motor 9 are started to work, and the feed is poured into the shell 1 from the feeding unit 5. The bracket 3 supports the vibration motor 4. The connection between the bracket 3 and the vibration motor 4 can adopt a spring to increase the vibration frequency of the shell 1. The shell 1 drives the screen plate 2 to vibrate, and the feed added into the shell 1 from the feeding unit 5 falls on the screen plate 2. Because the screen plate 2 is placed at an angle, the feed falling on the screen plate 2 moves down until the feed contacts the flow rod 10. The flow rod 10 Large-particle feed is intercepted, and small-particle feed passes through the bottom of the drainage rod 10 and is screened. The small-particle feed screened on the screen plate 2 is finally discharged from the first discharge port 7. The driving motor 9 drives the drainage rod 10 to rotate, and the spiral blades 11 on the outer wall of the drainage rod 10 drive the intercepted large-particle feed to move toward the discharge trough 12. With the vibration of the vibration motor 4, the small-particle feed entrained in the large-particle feed can be separated and vibrated out from the bottom of the drainage rod 10 through the screen plate 2 for screening. The spiral blades 11 drive the large-particle feed to fall from the discharge trough 12 to the discharge hopper 13 for discharge, so that when the feed is screened, the large-particle feed can be discharged through drainage, thereby improving the screening efficiency. During drainage, there will be no accumulation or small-particle feed entrained and discharged, so that the feed screening is continuous and the screening degree of the feed is improved.
[0029] Among them, the vibration motor 4 and the drive motor 9 mentioned above can be purchased on the market. They are mature technologies and have been fully disclosed, so they are not repeated in the specification. The vibration motor 4 and the drive motor 9 are equipped with power connection lines, and they are electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power lines, and the main controller can be a conventional known device such as a computer that plays a control role.
[0030] like Figure 3 , 4As shown, the adjustment unit 6 includes an adjustment block 61, which is slidably connected to the adjustment groove 15. A screw 62 is fixedly connected to the upper surface of the adjustment block 61.

The drainage rod 10 is rotatably connected between the two adjustment blocks 61, and the drive motor 9 is installed on the outer wall of one of the adjustment blocks 61; the drive motor 9 and the drainage rod 10 are connected by two adjustment blocks 61, and the screw 62 is raised or lowered by rotating the first nut 63 to drive the adjustment block 61 to slide in the adjustment groove 15. The adjustment groove 15 restricts the adjustment block 61, thereby adjusting the distance between the drainage rod 10 and the screen plate 2. According to the particle size of the feed, the drainage rod 10 and the screen plate 2 can be adjusted to different distances to adapt to the drainage screening of feeds with different particle sizes, thereby improving adaptability.
[0031] like Figure 3 , 4 As shown, the inner bottom surface and the top surface of the adjustment groove 15 are both provided with a clearance groove 16, and the adjustment unit 6 also includes two shielding plates 64, which are fixedly connected to the bottom surface and the upper end surface of the adjustment block 61 respectively, and the two shielding plates 64 are slidably connected to the two clearance grooves 16 respectively; the adjustment block 61 can shield the adjustment groove 15 through the shielding plates 64 at both ends thereof, so that the feed will not be exposed from the adjustment groove 15, and when the adjustment block 61 is adjusted in height, the shielding plates 64 slide in the clearance groove 16, thereby improving practicality.
[0032] like Figure 3 , 4 As shown, the adjustment unit 6 also includes a second nut 65, which is threadedly connected to the outer wall of the screw rod 62, and the second nut 65 is located in the adjustment groove 15; by threading the second nut 65 on the outer wall of the screw rod 62, after the position adjustment of the adjustment block 61 is completed, the first nut 63 is abutted against the upper surface of the shell 1, and then the second nut 65 is rotated to abut against the inner top wall of the adjustment groove 15, thereby restricting the screw rod 62, so that the adjustment block 61 remains stable and cannot move, thereby improving the stability of the drainage rod 10 in draining the feed.
[0033] like Figure 2 , 4 As shown, a guide inclined plate 14 is fixedly connected to the upper surface of the screen plate 2, and the guide inclined plate 14 blocks the position obliquely above the discharge trough 12; after the feed falls on the screen plate 2, it slides downward, and the guide inclined plate 14 blocks the discharge trough 12, so that the feed will not directly fall into the discharge trough 12 and be discharged under the guidance of the guide inclined plate 14, thereby improving practicality.
[0034] like Figure 2As shown, the inner bottom surface of the shell 1 is an inclined structure, and the inclination direction of the inner bottom surface of the shell 1 is opposite to the inclination direction of the screen plate 2. A second discharge port 8 is provided on the side wall of the shell 1 at one end away from the first discharge port 7, and the second discharge port 8 corresponds to the lower end of the inner bottom surface of the shell 1; the feed screened by the screen plate 2 falls on the inner bottom surface of the shell 1, and with the vibration of the shell 1, the screened feed is discharged from the second discharge port 8, and the retained feed on the screen plate 2 is discharged from the first discharge port 7, so that feed particles of different sizes are discharged separately for easy collection.
[0035] like Figure 1 , 5 As shown, the feeding unit 5 includes a feeding hopper 51, which is fixedly connected to and communicated with the upper surface of the shell 1, and a slot 52 is provided on the side wall of the feeding hopper 51, in which an adjusting plate 53 is movably inserted; when adding feed into the shell 1, the feed is poured into the feeding hopper 51, and the adjusting plate 53 is pulled outward to make the feed fall from the feeding hopper 51 onto the screen plate 2 for screening, and the speed of feed feeding and screening is controlled by controlling the position of the adjusting plate 53 and the slot 52, so as to improve the adaptability and screening degree of feed screening.
[0036] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
