Description

Technical Field

[0001] The invention relates to the technical field of chicken farming equipment, and in particular to a feed stirring device for chicken farming. Background Art

[0002] Chicken is a kind of poultry. It originated from wild jungle fowl. Its domestication history is at least about 4,000 years, but it was not until around 1800 that chicken and eggs became mass-produced commodities. There are turkeys, black chickens, pheasants, etc. Chicken is also one of the 12 Chinese zodiac signs. Feed is the general term for food for all animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Stirring means turning the mixture by hand or with an instrument.

[0003] A stirring device is required during the processing of chicken feed, but the feed pipes of existing stirring devices are mostly straight pipes, which easily cause blockage when multiple materials enter at the same time, reducing the efficiency of feed stirring.

[0004] A Chinese patent with authorization announcement number CN209476049U discloses a feed mixing device for raising chickens, including a bottom plate, support blocks are fixedly connected to both sides of the top of the bottom plate, a mixing box is fixedly connected to the top of the support block, a feed hose is connected to the top of the mixing box, and a transmission box is fixedly connected to the top of the mixing box, which can drive the hose to swing left and right.

[0005] In the above scheme, the threaded plate in the transmission box drives the transmission column to move left and right, and the left and right movement of the transmission column drives the hose to swing left and right, so that the hose swings left and right during feeding, thereby achieving the effect of preventing feed blockage.

[0006] Although the above scheme solves the problem that the feed pipe of the traditional stirring device is mostly a straight pipe, which is easy to cause blockage when multiple materials enter at the same time, and improves the efficiency of feed stirring by avoiding hose blockage, there is still the problem that adding multiple materials into the hose at the same time and then stirring the materials after they enter the mixing drum will cause uneven stirring between the various materials. Summary of the invention

[0007] In view of the deficiencies in the prior art, the technical problem solved by the present invention is to provide a feed stirring device for chicken farming, which solves the problem that adding multiple materials into a hose at the same time and then stirring the materials after they enter the stirring drum will cause uneven stirring between the various materials.

[0008] In order to solve the above problems, the technical solution adopted by the present invention is: a feed mixing device for chicken farming, comprising a frame, a motor is fixed on the frame, the output shaft of the motor is arranged in the horizontal direction, and a rotating rod is fixed on the output shaft of the motor; a mixing drum arranged in the horizontal direction is fixed on the frame, and one end of the rotating rod away from the motor penetrates one end of the mixing drum and extends into the inside of the mixing drum; the rotating rod is rotatably sealed and connected with the mixing drum; a stirring paddle is fixed on the part of the rotating rod located inside the mixing drum; a feeding port is opened at the top of the mixing drum, a rotating shaft is fixed inside the feeding port, a flap that can block the feeding port is rotatably sleeved outside the rotating shaft, a torsion spring is arranged on the rotating shaft, one end of the torsion spring is fixed on the rotating shaft, and the other end of the torsion spring is fixed on the flap; a stopper is fixed at the bottom of the flap, and the stirring paddle can move the stopper when the stirring paddle rotates; the number of the stirring paddles and the feeding port is set to more than 2 and corresponds to each other; a discharging port is opened at the bottom of the mixing drum, a discharging pipe is fixedly connected to the discharging port, and a sealing cap is threadedly connected to the discharging pipe.

[0009] The technical principle of the technical scheme is as follows: the flap blocks the discharge port under the force of the torsion spring to prevent leakage from the discharge hopper, and the raw materials to be mixed are pre-placed in different discharge hoppers according to the proportion, and the motor is started, and the motor drives the rotating rod to rotate, and the rotating rod drives the stirring paddle to rotate, and the stirring paddle can touch the block at the lower end of the flap during the rotation, and when the stirring paddle touches the block, it can drive the block to rotate, and the block drives the flap to flip a certain angle, and the torsion spring stores energy, and the discharge port can be discharged during this process; then after the stirring paddle continues to rotate to a certain position, the stirring paddle is separated from the block, and under the force of the torsion spring, the flap and the block are reset; the material in each discharge hopper is added to the mixing drum in small amounts and multiple times, and the stirring paddle rotates to stir the material in the mixing drum, and finally all the materials are evenly mixed before the cover is opened, and the mixed chicken feed can be discharged from the discharge pipe.

[0010] The beneficial effect of the present scheme is as follows: compared with the chicken feed stirring device in the prior art, the existing chicken feed stirring device adds multiple materials into the hose at the same time and then stirs the materials after they enter the stirring drum, which will lead to uneven stirring between the various materials; while in the present application, different raw materials are pre-filled in multiple feed hoppers, and then when the stirring paddle touches the block during the rotation of the stirring paddle, the rotation of the block drives the flap to flip, so that multiple feed hoppers can be discharged at the same time, and when the stirring paddle continues to rotate until it is separated from the block, the flap drives the block to reset under the force of the torsion spring, and multiple raw materials are added in small quantities and multiple times repeatedly, thereby ensuring that the chicken feed is stirred evenly.

[0011] Furthermore, a through hole is provided at the bottom of one end face of the mixing drum away from the discharge port, and a connecting rod arranged in the horizontal direction is slidingly and sealedly connected in the through hole; the connecting rod can only move in the horizontal direction; one end of the connecting rod extends through the through hole into the mixing drum and is fixedly connected to a scraper.

[0012] After the feed is mixed, it is inconvenient to discharge the chicken feed from the mixing drum in the existing chicken feed mixing device; however, in the present application, a scraper is arranged inside the mixing drum, and the scraper can be driven by a connecting rod to reciprocate along the axis direction of the mixing drum, thereby accelerating the discharge of the chicken feed.

[0013] Furthermore, the bottom surface of the scraper is an arc surface that fits the inner bottom surface of the mixing drum.

[0014] The chicken feed at the bottom of the mixing drum can be scraped off and discharged as much as possible.

[0015] Furthermore, the top surface of the scraper is a straight line.

[0016] Reduce the space occupied by the scraper.

[0017] Furthermore, a handle is fixed to one end of the connecting rod away from the scraper.

[0018] Easy to move the connecting rod.

[0019] Furthermore, the number of the feed openings is set to 4, with the sizes gradually decreasing from left to right.

[0020] At least 4 kinds of raw materials can be added at the same time, and the corresponding size of the feed hopper can be matched according to the proportion of various raw materials in the chicken feed formula.

[0021] Furthermore, the connecting rod is provided with a through hole whose axis is arranged in the vertical direction, and a "7"-shaped block can be placed in the through hole. When the connecting rod moves to the extreme position in the direction away from the discharge port, the "7"-shaped block cooperates with the through hole to limit the connecting rod in the horizontal direction.

[0022] In the process of stirring chicken feed, it is necessary to prevent the connecting rod from sliding under the influence of the moving material in the mixing drum, thereby preventing the scraper from blocking the rotation of the stirring paddle.

[0023] Furthermore, the motor is a servo motor; a cavity is provided in the stirring paddle, and one end of the cavity far from the rotating rod passes through the end of the stirring paddle far from the rotating rod to form an opening, a limiting portion is provided at the opening of the cavity, a sliding block is slidably connected inside the cavity, a spring is provided in the cavity, one end of the spring is fixed to the bottom of the cavity, and the other end of the spring is fixed to the piston; a one-way air inlet valve and a one-way air outlet valve that connect the inside and outside of the cavity are provided on the end of the stirring paddle close to the rotating rod; the one-way air inlet valve is connected to the outside of the stirring drum, and the one-way air outlet valve is connected to an air storage chamber, which is provided inside the rotating rod; a pressure valve is provided on the air storage chamber, and the pressure valve is electrically connected to a controller, when the pressure in the air storage chamber is greater than or equal to the set value, the controller controls the pressure valve to open; when the pressure in the air storage chamber is less than the set value, the controller controls the pressure valve to close.

[0024] The motor rotates forward and reverse periodically, and the motor speed changes according to a sine curve; during the rotation of the motor, the slider is stretched by the centrifugal force to move the spring toward the mouth of the cavity, and the air outside the mixing drum is sucked into the cavity during this process; when the motor is reversing, there is a moment when the motor speed is zero, and the stirring paddle is stationary. At this time, the slider approaches the rotating rod under the force of the spring, and the air in the cavity is exhausted into the air storage chamber during this process. The motor rotates forward and reverse periodically, and the cavity intermittently inhales and exhausts air. The gas discharged from the cavity is stored in the air storage chamber. When the gas pressure in the air storage chamber is greater than or equal to the set value, the air storage chamber discharges high-speed flowing gas, and the high-speed flowing gas discharged from the air storage chamber stirs the chicken feed in the stirring paddle. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 It is a cross-sectional view of the overall structure of an embodiment of the present invention. DETAILED DESCRIPTION

[0026] The following is further described in detail through specific implementation methods:

[0027] The reference numerals in the drawings of the specification include:

[0028] The embodiment is basically as shown in the attached Figure 1 As shown: motor 10, rotating rod 11, mixing drum 12, mixing paddle 13, discharge port 15, flap 16, block 17, discharge pipe 18, cover 19, scraper 20, connecting rod 21, "7"-shaped block 22, handle 23, cavity 30, slider 31, spring 32, one-way air inlet valve 33, one-way air outlet valve 34, air inlet pipe 40, air outlet pipe 50, air storage chamber 60, and pressure valve 61.

[0029] A feed stirring device for chicken farming, such as Figure 1 As shown, it includes a frame (not shown in the figure), a motor 10 is fixed on the frame, the output shaft of the motor 10 is arranged horizontally to the right, and a rotating rod 11 is fixed on the output shaft of the motor 10; a mixing drum 12 arranged in the horizontal direction is fixed on the frame, the mixing drum 12 is a hollow cylindrical shape, the right end of the rotating rod 11 passes through the left end surface of the mixing drum 12 and extends to the inside of the mixing drum 12, the right end of the rotating rod 11 is close to the right end surface of the mixing drum 12, the rotating rod 11 and the mixing drum 12 are rotatably sealed and connected, and the rotating rod 11 and the mixing drum 12 are coaxially arranged; 4 groups of stirring paddles 13 are fixed on the part of the rotating rod 11 located inside the mixing drum 12, the number of each group of stirring paddles 13 is set to 2 and is evenly distributed on the rotating rod 11 in the circumferential direction, when viewed from the side of the mixing drum 12, the 4 groups of stirring paddles 13 overlap each other, and the end of the stirring paddle 13 away from the rotating rod 11 is at a certain distance from the inner wall of the mixing drum 12.

[0030] like Figure 1As shown, the top of the mixing drum 12 is provided with four discharge ports 15 from left to right, and the four discharge ports 15 correspond to the horizontal positions of the four groups of stirring paddles 13 one by one. The diameters of the four discharge ports 15 are in the ratio of 5:4:3:2 from left to right. The discharge port 15 at the far left is taken as an example for explanation. A rotating shaft (not shown in the figure) arranged in the horizontal left and right directions is fixed in the center of the discharge port 15, and a flap 16 is rotatably sleeved outside the rotating shaft. The flap 16 is a circular plate, and the diameter of the flap 16 is the same as the diameter of the discharge port 15. A torsion spring (not shown in the figure) is arranged on the rotating shaft, and one end of the torsion spring is fixed on the rotating shaft, and the other end of the torsion spring is fixed on the flap 16; a stopper 17 is fixed at the bottom center of the flap 16, and the stopper 17 is arranged in the vertical direction, and the stopper 17 is cylindrical, and the lower end of the stopper 17 extends into the mixing drum 12.

[0031] During the rotation of the stirring paddle 13, when the stirring paddle 13 moves to the upper limit position, the stirring paddle 13 can touch the stopper 17 and drive the stopper 17 to rotate, and the stopper 17 drives the flap 16 to flip a certain angle, and the torsion spring stores energy. During this process, the discharge port 15 can discharge materials; then after the stirring paddle 13 continues to rotate to a certain position, the stirring paddle 13 is separated from the stopper 17, and under the action of the torsion spring, the flap 16 and the stopper 17 are reset; the material in each discharge hopper is added to the mixing drum 12 in small amounts and multiple times, and the stirring paddle 13 rotates to stir the material in the mixing drum 12, thereby ensuring that the chicken feed is evenly mixed.

[0032] The other three hoppers unload materials in the same way.

[0033] like Figure 1 As shown, a discharge port is provided at the bottom of the right end surface of the mixing drum 12, a discharge pipe 18 is fixedly connected to the discharge port, and a cover 19 is threadedly connected to the right end of the discharge pipe 18. After the chicken feed is mixed, it is inconvenient to discharge the chicken feed from the mixing drum 12. Therefore, in this embodiment, an internal spline-shaped through hole is provided at the bottom of the left end surface of the mixing drum 12, and a connecting rod 21 arranged in the horizontal direction is slidably sealed in the through hole, and an external spline matching the internal spline in the through hole is provided on the connecting rod 21. The right end of the connecting rod 21 extends through the through hole into the mixing drum 12 and is fixedly connected to the scraper 20. The bottom surface of the scraper 20 is set as an arc surface that fits the bottom surface of the mixing drum 12, and the top surface of the scraper 20 is set as a straight line. A through hole with an axis arranged in the vertical direction is opened on the connecting rod 21, and a "7"-shaped block can be placed in the through hole. When the connecting rod 21 moves to the left to the extreme position, the "7"-shaped block is placed in the through hole, and the right end of the "7"-shaped block is against the left end surface of the mixing drum 12. A cubic handle 23 is fixed to the left end of the connecting rod 21.

[0034] The connecting rod 21 can only move in the horizontal direction. By moving the connecting rod 21 left and right, the scraper 20 can be driven to reciprocate left and right, thereby accelerating the discharge of the chicken feed; the setting of the handle 23 facilitates the movement of the connecting rod 21; the purpose of setting the bottom surface of the scraper 20 as an arc surface that fits the inner bottom surface of the mixing drum 12 is to scrape and discharge the chicken feed at the bottom of the mixing drum 12 to the maximum extent; setting the top surface of the scraper 20 as a straight line can reduce the space occupied by the scraper 20; the through hole and the "7"-shaped block cooperate to limit the connecting rod 21 in the horizontal direction, and in the process of stirring the chicken feed, it is prevented that the connecting rod 21 slides under the drive of the moving material in the mixing drum 12, resulting in the scraper 20 blocking the rotation of the stirring paddle 13.

[0035] The motor 10 in this embodiment is a servo motor; Figure 1 As shown, a cavity 30 is provided in the stirring paddle 13, and one end of the cavity 30 away from the rotating rod 11 passes through the end of the stirring paddle 13 away from the rotating rod 11 to form an opening, and a slider 31 is slidably connected inside the cavity 30, and the size of the opening of the cavity 30 is smaller than the size inside the cavity 30 to prevent the slider 31 from falling from the cavity 30; a spring 32 is provided in the cavity 30, one end of the spring 32 is fixed to the bottom of the cavity 30, and the other end of the spring 32 is fixed to the slider 31; a one-way air inlet valve 33 and a one-way air outlet valve 34 that connect the inside and outside of the cavity 30 are provided on the end of the stirring paddle 13 close to the rotating rod 11; an air inlet pipe 40 and an air outlet pipe 50 are fixed on the outer periphery of the rotating rod 11, and the air inlet pipe 40 and the air outlet pipe 50 are fixed on the outer periphery of the rotating rod 11. The left end of the mixing drum 12 is connected to the outside of the mixing drum 12, the right end of the air inlet pipe 40 is closed, and all the one-way air inlet valves 33 are connected to the air inlet pipe 40; the left end of the air outlet pipe 50 is connected to the leftmost cavity 30, and the right end of the air outlet pipe 50 is connected to the air storage chamber 60, which is opened in the right part of the rotating rod 11, and all the one-way air outlet valves 34 are connected to the air outlet pipe 50; the right end of the rotating rod 11 is provided with a pressure valve 61 that can connect the inside and outside of the air storage chamber 60, and the pressure valve 61 is electrically connected to a controller. When the pressure in the air storage chamber is greater than or equal to 0.8MPa, the controller controls the pressure valve 61 to open; when the pressure in the air storage chamber is less than 0.8MPa, the controller controls the pressure valve 61 to close. The pressure valve 61 is electrically connected to a delay relay, which is also electrically connected to the controller. After the controller sends a closing signal, the delay relay closes the pressure valve 61 after 10s through the controller.

[0036] The motor 10 rotates forward and reverse periodically, and the speed of the motor 10 changes according to a sine curve; during the rotation of the motor 10, the slider 31 is subjected to the centrifugal force to stretch the spring 32 to move toward the mouth of the cavity 30, and during this process, the cavity 30 sucks in the air outside the mixing drum 12; during the reversal of the motor 10, there is a moment in the middle when the speed of the motor 10 is zero, at which time the stirring paddle 13 is stationary, and the slider 31 is no longer subjected to the centrifugal force. The slider 31 approaches the rotating rod 11 under the force of the spring 32, and during this process, the air in the cavity 30 is exhausted into the air storage chamber 60. The motor 10 rotates forward and reverse periodically, and the cavity 30 intermittently inhales and exhausts air, and the gas discharged from the cavity 30 is stored in the air storage chamber 60. When the gas pressure in the air storage chamber 60 is greater than or equal to 0.8MPa, the air storage chamber 60 discharges high-speed flowing gas, and the high-speed flowing gas discharged from the air storage chamber 60 stirs the chicken feed in the mixing drum 12. The function of the delay relay is to extend the exhaust time of the air storage chamber 60.

[0037] The specific implementation process is as follows:

[0038] Grind the various raw materials for preparing chicken feed into powder in advance.

[0039] In the initial state, the connecting rod 21 is limited to the extreme position at the left end; the flap 16 blocks the discharge port 15 under the force of the torsion spring; four kinds of raw materials are pre-filled in the four discharge ports, the motor 10 is started, the motor 10 drives the rotating rod 11 to rotate, the rotating rod 11 drives the stirring paddle 13 to rotate, the stirring paddle 13 touches the stopper 17 and drives the stopper 17 to rotate, the stopper 17 drives the flap 16 to flip, the torsion spring stores energy, and the discharge port 15 can discharge materials during this process; then the stirring paddle 13 continues to rotate to a certain position, the stirring paddle 13 and the stopper 1 7 is disengaged, and under the action of the torsion spring, the flap 16 and the stopper 17 are reset; the stirring paddles 13 in each group of stirring paddles 13 move the stopper 17 in turn; the material in each lower hopper is added to the stirring drum 12 in small amounts and multiple times, and the stirring paddles 13 rotate to stir the material in the stirring drum 12. After the chicken feed is stirred, the cover 19 is opened, the "7"-shaped block is removed, and the handle 23 is held by hand to make the connecting rod 21 drive the scraper 20 to reciprocate left and right, and the stirred chicken feed is discharged from the discharge pipe 18 under the push of the scraper 20.

[0040] In the process of stirring the chicken feed, the motor 10 rotates forward and reverse periodically, and the cavity 30 intermittently inhales and exhausts air. The gas discharged from the cavity 30 is stored in the gas storage chamber 60. When the pressure in the gas storage chamber 60 exceeds the set value, the gas storage chamber 60 discharges high-speed flowing gas to blow the powder for preparing the chicken feed into a floating state. Combined with the stirring of the stirring paddle 13, it is beneficial to make the various raw materials mixed more evenly and improve the stirring efficiency.

[0041] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
