Traditional feed ratio methods often rely on manual operation, which has problems such as inaccurate ratio, low operating efficiency and feed waste. Therefore, it is necessary to develop an efficient and accurate quantitative ratio device for feed supplements, which can automatically control the ratio and delivery of supplements, improve the management level and production efficiency of feed, and meet the needs of modern aquaculture for automation and intelligent development.

[0003] After the feed supplement is proportioned, it will be injected into the mixing drum for stirring. In order to make the feed supplement more delicate and easy to digest, a certain amount of water is generally added while proportioning the feed to soften the feed. During the feed softening process, the stirring shaft in the mixing drum is also used for stirring so that the feeds of various components are fully mixed. Finally, the mixed feed in the mixing drum is poured out. Due to the setting of the stirring shaft in the existing mixing drum, the feed in the mixing drum will have residues after being poured out.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0032] Embodiment 1:

[0033] A quantitative proportioning device for livestock feed supplement, comprising a proportioning bin 1 and a stirring drum 2 below the proportioning bin 1; the outer wall of the stirring drum 2 is supported and connected by a bracket 21; the lower surface of the stirring drum 2 is fixedly connected to a motor 22; the inner central axis position of the stirring drum 2 is rotatably connected to a stirring shaft 3; the lower end of the stirring shaft 3 is connected to the output shaft of the motor 22; a discharge pipe 23 is provided on the bottom wall of the stirring drum 2; a receiving groove 31 is vertically provided on the outer wall of the stirring shaft 3; the upper end of the receiving groove 31 is rotatably connected to a stirring bar 4; the shape of the stirring bar 4 is adapted to the specification of the receiving groove 31; the upper end of the stirring drum 2 is movably sealed and connected to a movable disk 5; an axial hole 51 is provided through the center of the movable disk 5; the upper end of the stirring shaft 3 is movably sealed and connected to the axial hole 51; the lower surface of the movable disk 5 is connected to the proportioning bin 1 through a feed pipe 52; a plurality of the outer walls of the proportioning bins 1 are fixedly connected to mounting rings 11; the lower surface of the mounting ring 11 and the bracket 21 are connected by a vertical hydraulic cylinder 12.

[0034] In this embodiment, the center formed by the multiple proportioning bins 1 has an avoidance area 13; the avoidance area 13 is used to avoid the stirring shaft 3; the opening and closing of the feed pipe 52 is controlled by the feed valve; the opening and closing of the discharge pipe 23 is controlled by the discharge valve; the movable disk 5 is penetrated by a third valve 53.

[0035] In this embodiment, the vertical height of the inner bottom wall of the mixing drum 2 increases as it moves away from the discharge pipe 23; the lower surface of the movable disk 5 is adapted to the inner bottom wall of the mixing drum 2; and the lower surface of the movable disk 5 can contact the inner bottom wall of the mixing drum 2.

[0036] During operation, the staff will pre-load the feed of each component into different proportioning bins 1, and the proportioning bin 1 will be at the lower limit position to facilitate the loading of the feed. Then, the discharge valve and the third valve 53 will be closed, and the opening and closing of the feed valve will be controlled. If all the materials in the proportioning bin 1 need to be added to the mixing drum 2, all the feed valves in the feed pipes 52 will be opened. If only part of the materials in the proportioning bin 1 need to be squeezed into the mixing drum 2, the corresponding feed valves in the feed pipes 52 will be opened. The greater the degree of opening of the channel in the feed pipe 52 by the feed valve, the greater the feed speed, and vice versa. In this way, the control of the feed valve is completed, and then the control system will control the extension of the hydraulic cylinder 12, and the hydraulic cylinder 12 will drive the installation ring 1 during the extension process. 1 moves upward, and during the upward movement of the mounting ring 11, the multiple proportioning bins 1 on the inner side will be driven upward, and during the upward movement of the multiple proportioning bins 1, the feeding pipe 52 will be driven upward, and during the upward movement of the feeding pipe 52, the movable disk 5 will be driven upward, and during the upward movement of the movable disk 5, it will move on the inner side wall of the mixing drum 2, so that the movable disk 5 moves upward on the inner side wall of the mixing drum 2, and during the upward movement of the movable disk 5, the inner wall space of the mixing drum 2 will be enlarged to form a negative pressure, so that the feed in the proportioning bin 1 passes through the feeding pipe 52 and enters the mixing drum 2 under the dual effects of gravity and negative pressure. When the movable disk 5 moves up to the limit position and needs to continue feeding, the feeding valve is closed, the third valve 53 is opened, and the shortening of the hydraulic cylinder 12 will drive the proportioning bin 1, the feeding pipe 52 and the movable disk 5 to move downward, and the mixing drum 2 is turned on and off. The excess gas in the mixing drum 2 will flow out along the third valve 53, and then the feed valve will be opened. After closing the third valve 53, the movable disk 5 will be controlled to move upward again, thus completing the process of the feed in the proportioning drum entering the mixing drum 2. During the up and down movement of the proportioning bin 1, the feed in the proportioning bin 1 is also brought close to the feed pipe 52 under vibration and gravity, thereby ensuring the continuity of the feed; then the feed valve will be closed, and during the upward movement of the movable disk 5, the axial hole 51 of the movable disk 5 and the stirring shaft 3 will move, and the stirring bar 4 will be placed in the accommodating groove 31 under the action of gravity, which will not interfere with the movement of the axial hole 51 and the stirring shaft 3. After the feed in the mixing drum 2 is in place, the movable disk 5 also moves upward to the upper port position of the mixing drum 2, and the stirring bar 4 on the stirring shaft 3 is also located at the lower end of the movable disk 5. The stirring bar 4 will generate centrifugal force during the rotation of the stirring shaft 3, so that the lower end of the stirring bar 4 will rotate out of the receiving groove 31 under the action of the centrifugal force. After being unfolded, the stirring bar 4 will stir the feed in the stirring drum 2, so as to mix the feed in the stirring drum 2 and make the feed mixed evenly. The unfolding angle of the stirring bar 4 will increase as the rotation speed of the stirring shaft 3 increases. After the mixing of the feed is completed, the control system will control the motor 22 to stop rotating. The lower end of the stirring bar 4 will flip toward the receiving groove 31 after the centrifugal force disappears. The stirring bar 4 will flip to the notch position of the receiving groove 31 and stop moving.Then, when the discharge valve is controlled to be open, the hydraulic cylinder 12 is shortened, and the hydraulic cylinder 12 will drive the mounting ring 11 and the proportioning bin 1 to move downward. During the downward movement of the proportioning bin 1, the movable disk 5 will be driven to move downward in the mixing drum 2. The movable disk 5 will squeeze the feed and gas in the mixing drum 2. The feed in the mixing drum 2 is below the gas. The feed in the mixing drum 2 is discharged along the discharge pipe 23 during the pressure process. In addition, since the vertical height of the bottom wall of the mixing barrel increases as it moves away from the discharge pipe 23, the feed on the bottom wall of the mixing drum 2 will gather toward the discharge pipe 23. The movable plate 5 moves downward and squeezes the feed in the mixing drum 2. The movable plate 5 moves downward, and the shaft hole 51 and the mixing shaft 3 move. The mixing shaft 3 passes through the shaft hole 51 from top to bottom, and the feed on the surface of the mixing shaft 3 is scraped off by the lower end of the shaft hole 51. The mixing shaft 3 drives the stirring bar 4 to enter the shaft hole 51 from bottom to top, and the stirring bar 4 is squeezed by the lower end of the shaft hole 51. The stirring bar 4 is squeezed and avoids the containing groove 31. The stirring bar 4 is turned over into the containing groove 31, and the residual feed in the containing groove 31 is squeezed. The stirring bar 4 is adapted to the shape of the receiving groove 31, so that the feed can be fully squeezed out during the process of the stirring bar 4 flipping into the receiving groove 31. After the stirring bar 4 moves out from the upper end of the shaft hole 51 along with the stirring shaft 3, the stirring bar 4 is still located in the receiving groove 31 under the action of gravity, so that the movable plate 5 will not be affected by the up and down movement of the movable plate 5 on the outer wall of the stirring shaft 3. In the process of the movable plate 5 moving downward, the feed on the outer wall of the stirring shaft 3 is scraped off. On the other hand, the feed on the inner wall of the mixing drum 2 will be scraped away, so that the feed in the mixing drum 2 can be discharged to the maximum extent and the residual amount can be reduced. After the movable disk 5 moves down to the limit position, the discharge valve is controlled to be closed, the third valve 53 is opened, and then the movable disk 5 is controlled to move up, and the external gas will enter the mixing drum 2 along the third valve 53. Then, the discharge valve is opened again, the third valve 53 is closed, and the movable disk 5 is controlled to move down, so that the feed in the mixing drum 2 is fully discharged, and finally the discharge valve and the third valve 53 are closed;

[0037] In the present invention, the stirring bar 4 can be pressed into the receiving groove 31 on the outer wall of the stirring shaft 3 to avoid the stirring when the stirring is stopped, so that the movable disk 5 can move on the outer wall of the stirring shaft 3 and squeeze the feed in the stirring drum 2, so that the feed in the stirring drum 2 can be fully discharged even when the stirring shaft 3 is in the stirring drum 2, thereby maximally reducing the residual feed in the stirring drum 2 and avoiding the waste, cross infection and mildew of the feed in the stirring drum 2 as much as possible.

[0038] Embodiment 2:

[0039] The wall of the shaft hole 51 is provided with an annular groove 54; the upper end of the outer wall of the stirring shaft 3 is provided with an active groove 32; the active block 6 is slidably connected in the active groove 32; the active block 6 is connected to the bottom of the active groove 32 through a first spring 61; the active block 6 is provided with guide surfaces 62 facing upward and downward at the end away from the first spring 61; the active block 6 can be stuck into the annular groove 54 under the action of the first spring 61.

[0040] In this embodiment, the active groove 32 is slidably sealed and connected to the active block 6; a driven groove 33 is provided inside the stirring shaft 3; the driven groove 33 is movably sealed and connected to the driven rod 7 up and down; the upper end of the driven groove 33 is connected to the bottom of the active groove 32 through an air hole 34; the lower groove wall of the accommodating groove 31 is connected to the driven groove 33 through an L-shaped groove 35; the L-shaped block 71 is movably connected to the upper and lower parts of the L-shaped groove 35; the L-shaped block 71 is fixedly connected to the driven rod 7; a clamping groove 41 is provided at the end of the stirring bar 4 away from the hinge point; the stirring bar 4 is arc-shaped at the end away from the hinge point and toward the corresponding accommodating groove 31; the clamping groove 41 on the stirring bar 4 is aligned with the notch of the L-shaped groove 35 after the stirring bar 4 is placed in the accommodating groove 31; the end of the L-shaped block 71 can be moved up to be clamped in the clamping groove 41.

[0041] In this embodiment, the anti-blocking block 42 is connected to the anti-blocking block 42 in a sliding seal in the slot 41 ; the anti-blocking block 42 is connected to the bottom of the slot 41 via a second spring 43 .

[0042] In this embodiment, the outer wall of the stirring bar 4 away from the central axis of the stirring shaft 3 is adapted to the outer wall of the stirring shaft 3; the upper end of the L-shaped block 71 is slidingly and sealingly connected to the L-shaped groove 35; the lower end of the driven groove 33, the L-shaped groove 35 and the card groove 41 are all filled with gas and can be compressed; the upper end of the driven groove 33, the air hole 34 and the active groove 32 are filled with liquid.

[0043] During operation, after the feed in the mixing drum 2 is mixed, the movable disc 5 will move downward under control, and the movable disc 5 will drive the annular groove 54 to squeeze the active block 6 away from the guide surface 62 at one end of the first spring 61, so that the active block 6 is further retracted into the active groove 32. As the movable disc 5 continues to move downward, the upper end of the mixing shaft 3 will be exposed from the upper end of the shaft hole 51, and the active groove 32 at the upper end of the mixing shaft 3 will be exposed accordingly. The first spring 61 will give the active block 6 an elastic force, so that the active block 6 moves away from the bottom of the active groove 32, so that the end of the active block 6 away from the bottom of the active groove 32 extends out of the active groove 32, so that the space in the active groove 32 becomes larger to form a negative pressure, and the driven groove 33 is close to the active groove 32. The liquid medium at the upper end will enter the active groove 32 along the air hole 34 to be replenished, so that the driven rod 7 moves upward. The lower end of the driven rod 7 can also be provided with an elastic member to realize the upward movement of the driven rod 7. During the upward movement of the driven rod 7, the L-shaped block 71 will be driven to move upward, and the L-shaped block 71 will move upward in the L-shaped groove 35, so that one end of the L-shaped block 71 extends from the L-shaped groove 35 into the lower end of the corresponding receiving groove 31, completing the preparation action for the L-shaped block 71. As the movable plate 5 continues to move downward, the movable plate 5 will squeeze the stirring bar 4, so that the lower end of the stirring bar 4 will flip toward the receiving groove 31, and the arc surface of the lower end of the stirring bar 4 will squeeze the L-shaped block 71, so that the L-shaped block 71 is When the driven rod 7 moves downward, the active block 6 will move toward the bottom of the active groove 32, and the first spring 61 will be compressed. After the stirring bar 4 completely enters the accommodating groove 31, the groove 41 at the lower end of the stirring bar 4 is aligned with the upper end of the L-shaped groove 35, and the first spring 61 begins to reset. The active block 6 will move away from the bottom of the active groove 32, and the driven rod 7 will move upward accordingly. The driven rod 7 will drive the L-shaped block 71 to move upward, and the upper end of the L-shaped block 71 will be stuck in the corresponding groove 41. The elastic force of the first spring 61 is greater than that of the second spring 43, so that the anti-blocking block 42 in the groove 41 is squeezed by the L-shaped block 71 The second spring 43 is overcome to move toward the bottom of the slot 41, so that the L-shaped block 71 locks the stirring bar 4. When the movable disk 5 moves downward, all the stirring bars 4 are locked into the corresponding receiving slots 31. The stirring bars 4 are adapted to the receiving slots 31, so that the outer wall of the stirring shaft 3 is relatively smooth. In order to completely discharge the feed in the mixing drum 2, the movable disk 5 moves up and down, and the shaft hole 51 on the movable disk 5 moves with the stirring shaft 3. However, since the stirring bar 4 is locked into the receiving slot 31, the stirring bar 4 will not protrude from the receiving slot 31 as the movable disk 5 moves, thereby ensuring that the movable disk 5 can move up and down smoothly, thereby improving the stability of the proportioning device.During the process of the movable disk 5 moving up and down to discharge the feed in the mixing drum 2, it is necessary to keep the active groove 32 above the movable disk 5. After the movable disk 5 moves down to the limit position, a new round of feed mixing is carried out. In order to make the feed enter the mixing drum 2 better, the movable disk 5 will also move up and down. The active groove 32 is higher than the movable disk 5, thereby ensuring that the stirring bar 4 is locked in the accommodating groove 31. The stirring bar 4 is retracted to avoid blocking the feed from moving down. After the feed is fed and the next step of mixing is carried out, the movable disk 5 moves up to squeeze the active block 6, and the active block 6 is compressed back into the active groove 32. When the active groove 32 is aligned with the annular groove 54, the active block 6 is partially stuck in the annular groove by the action of the first spring 61. The groove 54 realizes the temporary positioning of the movable disk 5 and the stirring shaft 3, thereby reducing the risk of the movable disk 5 moving down, making the stirring process more stable. When the active block 6 is partially inserted into the annular groove 54, the liquid medium in the active groove 32 is still under pressure, and the medium in the active groove 32 will enter the driven groove 33 along the air hole 34, so that the driven rod 7 moves down while driving the L-shaped block 71. The L-shaped block 71 will move out of the slot 41 and retract into the L-shaped groove 35 at one end, so that the stirring bar 4 in the accommodating groove 31 is unlocked. As the stirring shaft 3 rotates, the stirring bar 4 will unfold, and the second spring 43 will also push the anti-blocking block 42 away from the slot 41, so that the slot 41 is blocked, and the feed is prevented from entering the slot 41 and causing blockage. ;

[0044] Embodiment 3:

[0045] The movable plate 5 is penetrated by a pipe sleeve 8 from top to bottom; a fourth valve is arranged in the pipe sleeve 8; and the fourth valve is located just above the highest position of the inner bottom wall of the mixing drum 2.

[0046] In this embodiment, the inner side of the pipe sleeve 8 is movably sealed and connected to the extension pipe 81; the upper end of the extension pipe 81 is connected to the upper end of the pipe sleeve 8 by an elastic rope 82; the lower end of the extension pipe 81 extends to the inner bottom wall of the mixing drum 2; the lower end of the extension pipe 81 is provided with a toothed opening.

[0047] During operation, when the feed enters the mixing drum 2, the fourth valve is in a non-operating state, and the third valve 53 is in an operating state. When the movable disk 5 moves downward, the third valve 53 is opened, and the gas in the mixing drum 2 is pressed and squeezed out along the third valve 53. When the movable disk 5 moves upward, the third valve 53 is closed, so that the feed pipe 52 can feed. For details of the specific process, see Example 1;

[0048] During the feed stirring process, the fourth valve is in a closed state, and the stirring bar 4 will not interfere with the extension tube 81;

[0049] During the discharge of the feed in the mixing drum 2, the fourth valve is in a working state, and the third valve 53 is in a non-working state. During the downward movement of the movable disk 5, the fourth valve is closed, the discharge valve is opened, and the feed in the mixing drum 2 is discharged along the discharge pipe 23. In order to discharge all the feed in the mixing drum 2 and to improve the discharge efficiency of the feed in the mixing drum 2, the movable disk 5 moves up and down. During the upward movement of the movable disk 5, the discharge valve is closed, the fourth valve is opened, the space in the mixing drum 2 is expanded to form a negative pressure, and the external gas flows from top to bottom along the extension tube 81, and finally flows into the mixing drum 2 along the lower end of the extension rod. The airflow will impact the surrounding feed, so that the feed is not easy to accumulate at the high position of the bottom wall of the mixing drum 2, so that the feed on the bottom wall of the mixing drum is blown from a high position to a low position, so that the feed on the bottom wall of the mixing drum can quickly gather toward the feed pipe 52, and then when the movable disk 5 moves down again, the discharge efficiency of the feed in the mixing drum 2 is greatly improved, and the residual feed is further avoided;

[0050] During the up and down movement of the movable plate 5 in this embodiment, the elastic rope 82 is always in a pulled state, so that the elastic rope 82 gives elastic force to the extension tube 81 against the inner bottom wall of the mixing drum 2, thereby ensuring the stability of the extension tube 81.
