Description
Technical Field
[0001] The present invention relates to the technical field of livestock breeding feed mixing, and particularly relates to a feed mixing device for livestock breeding. Background Art
[0002] In the process of livestock breeding, the feed mixing device plays a crucial role. It can mix different types of feed raw materials in a certain proportion to ensure that livestock obtain comprehensive and balanced nutrition. This can not only improve the growth rate and health status of livestock, but also reduce feed waste and breeding costs. Therefore, the performance and quality of the feed mixing device have an important impact on the benefits of the livestock breeding industry.
[0003] Although some existing feed mixing devices for livestock breeding can achieve a certain degree of feed mixing, they have high requirements for the physical properties of feed and poor adaptability, and it is difficult to meet the mixing requirements of different types and specifications of feed.
[0004] In summary, the problem of poor adaptability of some existing feed mixing devices for livestock breeding has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a feed mixing device for livestock breeding. Summary of the Invention
[0005] To solve the above problems, the present invention provides a feed mixing device for livestock breeding. By using a material transfer box to transfer feed periodically, the addition progress of the feed is effectively controlled. While improving the adaptability of the feed mixing device, the added feed can be fully mixed, improving the mixing efficiency and mixing quality between feeds.
[0006] To achieve the above object, the technical solution of the present invention is as follows: A feed mixing device for livestock breeding, including an upper housing, the bottom of the upper housing is detachably connected to a lower housing, a feed inlet frame is fixedly connected to the side wall of the lower housing, the lower housing communicates with the outside through the feed inlet frame, a feeding port is opened at the top of the upper housing, a discharge port is opened at the side wall of the lower housing, and a controller is further included. A fixed frame is fixedly connected to the top of the lower housing, and a storage frame is fixedly connected to the top of the fixed frame.
[0007] A fixing plate and a driving member are fixedly connected to the top of the lower housing. The controller is used to control the rotation of the output shaft of the driving member. The output shaft of the driving member penetrates through the fixing plate and is fixedly connected to a rotating disc. A chute in the shape of a "convex" character is opened on the rotating disc. A sliding rod is slidably fitted in the chute. One end of the sliding rod away from the chute is fixedly connected to an L-shaped transmission plate, and the corner of the transmission plate is hinged to the side wall of the fixing plate.
[0008] A transmission rod is hinged to the side of the transmission plate away from the fixing plate, and a swinging rod is hinged to the side wall of the fixing plate. One end of the transmission rod away from the transmission plate is hinged to the middle of the swinging rod.
[0009] A rotating shaft is rotatably fitted on the swing rod. At both ends of the rotating shaft, a material transfer box and a limit block are respectively fixedly connected. On one side of the limit block away from the rotating shaft, a limit shaft is eccentrically fixedly connected. A limit groove is formed on the fixed plate, and the limit shaft is located in the limit groove and is in transverse sliding fit with the fixed plate.
[0010] A material transfer cylinder is connected to the material transfer box. At one end of the material transfer cylinder away from the material transfer box, a material transfer solenoid valve is connected. An outlet solenoid valve is connected to the side wall of the storage frame, and an inlet solenoid valve is connected to the top of the lower housing. The controller is used to control the opening and closing of the material transfer solenoid valve, the outlet solenoid valve, and the inlet solenoid valve.
[0011] A stirring assembly for stirring feed is provided on the output shaft of the driving member.
[0012] The technical principle of the above solution is as follows:
[0013] The staff adds the feed to be mixed into the lower housing through the feed frame, and adds the feed to be added into the upper housing through the feeding port, so that it enters the storage frame.
[0014] The staff controls the rotation of the output shaft of the driving member through the controller, so that it drives the rotating disk to rotate. During the rotation of the rotating disk, the sliding groove is driven to rotate, so that the sliding rod slides in the sliding groove. During the sliding process of the sliding rod, the transmission plate, the transmission rod, the swing rod, and the rotating shaft are successively driven to swing horizontally. The rotating shaft drives the limit block to swing horizontally, and the limit block drives the limit shaft to slide horizontally in the limit groove.
[0015] The rotating shaft also drives the material transfer box to swing horizontally. During the swinging process, the limit block drives the rotating shaft to rotate, the rotating shaft drives the material transfer box to rotate, and the material transfer box drives the material transfer cylinder to rotate, so that it is communicated with the storage frame through the material transfer solenoid valve and the outlet solenoid valve. The staff controls the material transfer solenoid valve and the outlet solenoid valve to open for 2 - 5 minutes and then close through the controller. During this period, the staff controls the output shaft of the driving member to stop rotating, so that the feed in the storage frame enters the material transfer box. The staff controls the rotation angle of the output shaft of the driving member, so that the material transfer cylinder is communicated with the inside of the lower housing through the material transfer solenoid valve and the inlet solenoid valve. Then, the staff controls the output shaft of the driving member to stop rotating, opens the material transfer solenoid valve and the inlet solenoid valve, and transfers the feed in the material transfer box to the inside of the lower housing.
[0016] During the rotation of the output shaft of the driving member, the stirring assembly is also driven to operate to stir and mix the feed inside the lower housing.
[0017] Adopting the above solution has the following beneficial effects:
[0018] 1. In the present invention, by using a transfer box to transfer feed cyclically, the feeding progress of the feed is effectively controlled. While improving the adaptability of the feed mixing device, the added feed can be fully mixed, thus improving the mixing efficiency and quality between feeds.
[0019] 2. In the present invention, due to the detachable connection between the upper housing and the lower housing, it is more convenient for the staff to clean and maintain the inside of the feed mixing device. At the same time, it is also convenient to replace or upgrade components when needed.
[0020] 3. In the present invention, through the precise control of the transfer solenoid valve, the discharge solenoid valve and the feed solenoid valve by the controller, the proportional addition and mixing of different types of feeds can be achieved, ensuring that the nutritional components in each portion of the feed are balanced and consistent.
[0021] Further, the stirring assembly includes a first bevel gear coaxially and fixedly connected to the output shaft of the driving member. The first bevel gear meshes with a second bevel gear. The second bevel gear is coaxially and fixedly connected with a stirring shaft. The stirring shaft penetrates through the top wall of the lower housing and extends into the interior of the lower housing to be rotationally matched with the inner bottom wall of the lower housing. A plurality of stirring blades are circumferentially and fixedly connected to the lower part of the stirring shaft.
[0022] Beneficial effects: The stirring assembly realizes the power transmission from the driving member to the stirring shaft through the meshing of the first bevel gear and the second bevel gear. This gear transmission method has the characteristics of high transmission efficiency and stable operation, ensuring that the stirring shaft can rotate stably and continuously.
[0023] Further, a partition is fixedly connected to the inner side wall of the lower housing. The partition divides the interior of the lower housing into a storage cavity and a stirring cavity in sequence from left to right. An opening and closing door is hinged to the side wall of the storage cavity.
[0024] Beneficial effects: The partition clearly divides the interior of the lower housing into two areas, namely a storage cavity and a stirring cavity. The storage cavity can be used to temporarily store feed raw materials to be mixed or the mixed feed, while the stirring cavity is the main place for feed mixing. This functional partition makes the operation more orderly and avoids the confusion between feed raw materials and mixed feed.
[0025] Further, a stirring limiting frame is fixedly connected to the top wall of the stirring cavity. The stirring shaft is located in the stirring limiting frame and is rotationally matched with the stirring limiting frame.
[0026] Beneficial effects: The stirring limiting frame provides stable support for the stirring shaft, enabling it to rotate stably during the stirring process. This helps to reduce the shaking and vibration of the stirring shaft and improve the stirring efficiency.
[0027] Further, a sealing ring is fixedly connected to one end of the transfer cylinder close to the transfer solenoid valve.
[0028] Beneficial effects: The design of the sealing ring can effectively prevent the leakage of feed during the transfer process, ensuring the smooth transfer of feed, avoiding waste of feed and contamination of the feed mixing device.
[0029] Furthermore, a limiting baffle is provided above the feed solenoid valve. The bottom of the limiting baffle is fixedly connected to the top of the lower housing, and the limiting baffle is located in the movement path of the transfer cylinder.
[0030] Beneficial effects: The presence of the limiting baffle provides a clear movement boundary for the transfer cylinder. During the feed mixing and transfer process, the transfer cylinder needs to move precisely to a specified position to ensure the smooth discharge of feed. The limiting baffle can guide the transfer cylinder to move along a predetermined path, preventing it from deviating from the track, thus ensuring the accuracy and stability of the transfer cylinder's movement.
[0031] Furthermore, the limiting baffle is U-shaped.
[0032] Beneficial effects: The U-shaped limiting baffle can fit more closely to the outside of the transfer cylinder, enabling it to better adapt to the shape changes of the transfer cylinder and preventing feed from leaking out through the gap between the transfer cylinder and the lower housing during the transfer process.
[0033] Furthermore, buffer layers are fixedly connected to both the transfer cylinder and the limiting baffle.
[0034] Beneficial effects: The buffer layer can reduce the direct collision between the transfer cylinder and the limiting baffle during movement, thereby reducing the wear degree of the transfer cylinder and the limiting baffle. This helps to extend the service life of the transfer cylinder and the limiting baffle and reduce the maintenance and replacement costs.
[0035] Furthermore, a guiding frame is fixedly connected at the feeding port.
[0036] Beneficial effects: The guiding frame can guide the feed to accurately enter the feeding port, ensuring that the feed does not scatter or deviate from the predetermined path. This helps to reduce waste of feed and improve the utilization rate of feed. At the same time, the design of the guiding frame can also prevent external impurities from entering the interior of the feed mixing device, maintaining the cleanliness of the feed mixing device and the hygiene of the feed.
[0037] Furthermore, a discharge plate is hinged at the discharge port.
[0038] Beneficial effects: The discharge plate is connected to the discharge port by a hinge, enabling the staff to flexibly open or close the discharge port. This design allows the staff to control the discharge of feed as needed at any time.
[0039] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed description of the specific implementation
[0044] The following is a further detailed description through specific implementation manners:
[0045] Example 1:
[0046] As shown in the attached Figure 1 , Figure 2 and Figure 3 shown: A feed mixing device for livestock breeding, including an upper housing 1, the bottom of the upper housing 1 is detachably connected to a lower housing 2 by bolts, a feed inlet frame 3 is integrally formed on the side wall of the lower housing 2, the lower housing 2 communicates with the outside through the feed inlet frame 3, a feeding port is opened at the top of the upper housing 1, a guide frame 4 is integrally formed at the feeding port, a discharge port is opened on the side wall of the lower housing 2, and a discharge plate 5 is hinged at the discharge port.
[0047] It further includes a controller, a fixed frame 6 is welded on the top of the lower housing 2, and a storage frame 7 is integrally formed on the top of the fixed frame 6.
[0048] A fixed plate 8 and a driving member are fixedly connected to the top of the lower housing 2 by bolts. The controller is used to control the rotation of the output shaft of the driving member. The output shaft of the driving member penetrates through the fixed plate 8 and is fixedly connected to a rotating disk 9 by bolts. A chute in the shape of a "convex" character is opened on the rotating disk 9. A sliding rod is slidably fitted in the chute. One end of the sliding rod away from the chute is integrally formed with an L-shaped transmission plate 10. The corner of the transmission plate 10 is hinged to the side wall of the fixed plate 8. In this embodiment, the driving member is selected as a stepping motor.
[0049] One side of the transmission plate 10 away from the fixed plate 8 is hinged with a transmission rod 11, and one side wall of the fixed plate 8 is hinged with a swing rod 12. One end of the transmission rod 11 away from the transmission plate 10 is hinged with the middle part of the swing rod 12.
[0050] A rotating shaft is rotationally fitted on the swing rod 12. Two ends of the rotating shaft are respectively welded with a material transfer box 13 and a limiting block 14. One side of the limiting block 14 away from the rotating shaft is integrally formed with a limiting shaft eccentrically. A limiting groove is formed on the fixed plate 8, and the limiting shaft is located in the limiting groove and is in transverse sliding fit with the fixed plate 8.
[0051] A material transfer cylinder 15 is communicated with the material transfer box 13. One end of the material transfer cylinder 15 away from the material transfer box 13 is communicated with a material transfer solenoid valve 16. One side wall of the storage frame 7 is communicated with a discharge solenoid valve 17. The top of the lower shell 2 is communicated with a feed solenoid valve 18. The controller is used to control the opening and closing of the material transfer solenoid valve 16, the discharge solenoid valve 17 and the feed solenoid valve 18. A sealing ring is fixedly adhered to one end of the material transfer cylinder 15 close to the material transfer solenoid valve 16.
[0052] A stirring assembly for stirring feed is arranged on the output shaft of the stepping motor.
[0053] The stirring assembly includes a first bevel gear 19 coaxially and fixedly clamped on the output shaft of the stepping motor. The first bevel gear 19 meshes with a second bevel gear 20. The second bevel gear 20 is coaxially and fixedly clamped with a stirring shaft 21. The stirring shaft 21 penetrates through the top wall of the lower shell 2 and extends into the lower shell 2, and is in rotational fit with the inner bottom wall of the lower shell 2. A plurality of stirring blades 22 are integrally formed on the lower part of the stirring shaft 21 in the circumferential direction.
[0054] The specific implementation process is as follows: The staff determines the feed ratio to be mixed, and respectively adds them into the lower shell 2 and the storage frame 7 through the feed frame 3 and the guiding frame 4 according to the types of feed to be mixed.
[0055] The staff controls the rotation of the output shaft of the stepping motor through the controller, so that it drives the rotating disk 9 to rotate. The rotating disk 9 drives the sliding groove to rotate, so that the sliding rod slides in the sliding groove. During the sliding process of the sliding rod, it drives the transmission plate 10, the transmission rod 11, the swing rod 12 and the rotating shaft to swing horizontally in sequence.
[0056] During the horizontal swinging process of the rotating shaft, it drives the material transfer box 13 and the limiting block 14 to swing horizontally. The limiting block 14 drives the limiting shaft to slide horizontally in the limiting groove. The limiting block 14 rotates under the limiting action of the limiting shaft, so that it drives the rotating shaft to rotate. The rotating shaft drives the material transfer box 13 to rotate together with it during the horizontal swinging process.
[0057] During the rotation of the material transfer box 13, the material transfer cylinder 15 is driven to rotate. The staff sets the rotation angle of the output shaft of the stepper motor through the controller, so that the material transfer cylinder 15 is connected to the storage box 7 through the material transfer solenoid valve 16 and the discharge solenoid valve 17. The controller sets the material transfer solenoid valve 16 and the discharge solenoid valve 17 to open for 2 minutes, and the output shaft of the stepper motor stops rotating for 2 minutes, so that the feed in the storage box 7 enters the material transfer box 13.
[0058] After 2 minutes, the controller restarts the output shaft of the stepper motor to make the feed mixing device continue to operate. When the material transfer cylinder 15 rotates above the feed solenoid valve 18 and the material transfer box 13 is connected to the inside of the lower housing 2 through the material transfer solenoid valve 16 and the feed solenoid valve 18, the controller controls the output shaft of the stepper motor to stop rotating for 2 minutes again. During this period, the material transfer solenoid valve 16 and the feed solenoid valve 18 are in the open state, and the feed in the material transfer box 13 is transferred into the lower housing 2.
[0059] When the output shaft of the stepper motor rotates, it will also drive the first bevel gear 19 to rotate. The first bevel gear 19 drives the second bevel gear 20 to rotate. The second bevel gear 20 drives the stirring shaft 21 to rotate. The stirring shaft 21 drives the stirring blades 22 to rotate, and the feed in the lower housing 2 is stirred and mixed.
[0060] During the transfer of the feed, the sealing ring seals its transfer channel, reducing its loss.
[0061] By using the material transfer box 13 to transfer the feed periodically, the addition progress of the feed is effectively controlled. While improving the adaptability of the feed mixing device, the added feed can be fully mixed, improving the mixing efficiency and mixing quality between the feeds.
[0062] Embodiment 2:
[0063] As shown in the appendix Figure 2 and Figure 3 The difference from Embodiment 1 is that a partition plate 23 is welded to the inner side wall of the lower housing 2. The partition plate 23 divides the inside of the lower housing 2 into a storage cavity and a stirring cavity from left to right in sequence. A hinged door 24 is hinged to the side wall of the storage cavity.
[0064] The specific implementation process is as follows: The storage cavity provides an additional placement point for the staff to store the feed. When adding feed is required, the staff can take out the feed in the storage cavity and directly add it. The design of the hinged door 24 protects the feed stored inside the storage cavity and reduces the external pollution it receives.
[0065] Embodiment 3:
[0066] As shown in the appendix Figure 3As shown, the difference from Embodiment 2 is that a stirring limiting frame 25 is welded to the top wall inside the stirring cavity, and the stirring shaft 21 is located in the stirring limiting frame 25 and rotatably engaged with the stirring limiting frame 25.
[0067] The specific implementation process is as follows: When the stirring shaft 21 rotates, the stirring limiting frame 25 can limit it, thereby improving the stability of the stirring shaft 21 during rotation. As a result, the feed in the stirring cavity can be fully mixed, improving the mixing quality of the feed.
[0068] Embodiment 4:
[0069] As shown in the attached Figure 2 and Figure 3 As shown, the difference from Embodiment 3 is that a U-shaped limiting baffle 26 is provided above the feed electromagnetic valve 18. The bottom of the limiting baffle 26 is welded to the top of the lower housing 2. The limiting baffle 26 is located in the movement path of the material transfer cylinder 15, and buffer layers are fixedly adhered to both the material transfer cylinder 15 and the limiting baffle 26.
[0070] The specific implementation process is as follows: The design of the U-shaped limiting baffle 26 enables the material transfer cylinder 15 to be limited during rotation, reducing the occurrence of feed transfer failure caused by excessive rotation of the material transfer cylinder 15. Its U-shaped design fits the shape of the limiting cylinder, and combined with the design of the buffer layer, it reduces the mechanical damage suffered by the material transfer cylinder 15 and the limiting baffle 26.
[0071] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill 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 the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
