[0002] Pig feed is vital in the pig farming industry. By providing comprehensive nutritional support, it can not only accelerate the growth rate of pigs, improve their health and production performance, but also enhance their immunity, optimize feed conversion rate, and reduce the risk of disease, thereby maximizing breeding benefits and environmental protection, and ensuring the sustainable development of farms. The raw materials for pig feed production and processing include the following ingredients, such as energy feeds such as corn kernels, wheat and barley, which can provide the energy needed for pig growth.

[0004] However, when crushing corn kernels with a high moisture content, since the corn kernels contain a high content of sugar and starch, these components will be released during the crushing process and coated on the hammer head under the action of moisture. After long-term use, the coating layer on the outer wall of the hammer head will gradually thicken. In particular, when the friction between the hammer head and the corn kernels generates heat, the sugar will become more viscous, increasing the possibility of adhesion, which not only makes the corn kernels more likely to adhere to the outer wall of the hammer head, but also increases the difficulty of cleaning the hammer head and the frequency of maintenance.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 7 The present invention provides a technical solution: a pig feed processing crushing and granulating device, comprising a shell 1, a fixed sleeve 2 is fixedly installed at the center of the shell 1 through a connecting rod, a hammer rod 3 that can slide vertically up and down is installed inside the fixed sleeve 2, a hammer head 6 is fixedly connected to the bottom of the hammer rod 3, two cleaning plates 7 that can be opened or closed are installed on the inner wall of the shell 1, the cleaning plate 7 is semi-barrel-shaped, and cleaning cotton is installed on the inner wall of the cleaning plate 7, and the cleaning cotton can fit the outer wall of the hammer head 6 when the cleaning plate 7 is closed;

[0031] The utility model also comprises a hammering part arranged below the hammering head 6, and the hammering head 6 can cooperate with the hammering part to smash the corn kernels.

[0032] See also Figures 1 to 7 When corn kernels need to be crushed to make pig feed, the corn kernels to be crushed are first put into the hammer part, and the hammer rod 3 is moved up and down by an external driving component, thereby driving the hammer head 6 to crush the corn kernels in the hammer part, and the corn kernels are broken in an automatic impact mode, avoiding the loss caused by the use of a grinder. Compared with a grinder, the manufacturing cost is lower, the durability is stronger, and the failure rate is lower.

[0033] During the hammering process of the hammer head 6, the corn kernels will be hammered into smaller particles. These corn broken particles will adhere to the outer wall of the hammer head 6 under the action of water and sugar. Although some corn broken particles can be shaken off during the continuous hammering process of the hammer head 6, the corn broken particles are small and stubbornly adhere to the outer wall of the hammer head 6 under the action of water and sugar. Such stubborn broken particles may not only cause equipment failure, but also corrode the hammer head 6 as they gradually accumulate. If the adhesion time is too long, the corn broken particles may deteriorate. The spoiled broken particles will be used to make feed together with the corn kernels crushed next time, thereby affecting the nutritional value and safety of the feed, and may even cause animal health problems. In summary, it is particularly important to clean the corn broken particles adhered to the outer wall of the hammer head 6. The specific implementation method is as follows:

[0034] When the hammer head 6 separates from the corn kernels and moves upward, the two cleaning plates 7 will close, and the cleaning cotton on the inner wall of the cleaning plate 7 will fit with the outer wall of the hammer head 6. When the hammer head 6 moves upward, the corn kernels adhering to the outer wall of the hammer head 6 will be wiped off by the friction between the outer wall of the hammer head 6 and the cleaning cotton; when the hammer head 6 moves downward, the two cleaning plates 7 will gradually separate from the hammer head 6, so that the wiped corn kernels fall into the hammer part.

[0035] Therefore, each time the hammer head 6 rises after hammering and crushing the corn kernels, the outer wall of the hammer head 6 can be cleaned by cleaning cotton to keep the outer wall of the hammer head 6 clean, reduce the adhesion of materials, ensure that the hammer head 6 always works in the best condition, improve the crushing efficiency, reduce the wear caused by the adhesion of materials, and thus extend the service life of the equipment. It can also be done without affecting the normal operation of the equipment, reducing downtime, improving production efficiency, reducing the direct contact between operators and equipment, and reducing safety risks during the cleaning process.

[0036] Furthermore, the inner walls on both sides of the housing 1 are rotatably connected to rotating rods 9 through pins, and cavities are opened inside the two rotating rods 9. The outer wall of the hammer rod 3 is rotatably connected to the sliding sleeve 4. The outer walls on both sides of the sliding sleeve 4 are rotatably installed with sliding rods 10 through pins. The two sliding rods 10 are respectively inserted into the cavities of the corresponding rotating rods 9, and the two sliding rods 10 are slidably connected to the penetration points of the outer walls of the corresponding rotating rods 9.

[0037] It also includes a connection portion that enables the cleaning plate 7 to be opened or closed when the rotating rod 9 swings.

[0038] See also Figure 2 as well as Figure 3When the external driving component drives the hammer rod 3 to move downward, it will drive the sliding sleeve 4 to move downward together, thereby driving the two sliding rods 10 to move downward and rotate, and then driving the two rotating rods 9 to rotate downward. When the two rotating rods 9 rotate downward, the two rotating rods 9 drive the two cleaning plates 7 to move in opposite directions through the connecting parts, so that the cleaning cotton on the cleaning plate 7 is separated from the hammer head 6, and the corn kernels wiped off the cleaning cotton fall back into the hammer part; when the hammer head 6 moves upward after hammering the corn kernels, similarly, the sliding sleeve 4 will drive the sliding rod 10 to rotate and move upward, and then the rotating rod 9 rotates upward. In the process of the rotating rod 9 rotating upward, the two cleaning plates 7 are driven to move in a direction close to each other through the connecting part, so that the cleaning cotton on the inner wall of the cleaning plate 7 fits with the outer wall of the hammer head 6, and the corn kernels adhering to the outer wall of the hammer head 6 are cleaned by friction.

[0039] Embodiment 1 provides a connection portion that enables the cleaning plate 7 to be opened or closed when the rotating rod 9 swings.

[0040] Furthermore, the connecting portion includes two first connecting rods 16 respectively fixedly connected to the bottoms of the two rotating rods 9 , and the two first connecting rods 16 are respectively fixedly connected to the tops of the two cleaning plates 7 .

[0041] As can be seen from the above, when the hammer head 6 moves downward to hammer the corn kernels, the rotating rod 9 will rotate downward along the axis of the pin shaft, see Figure 3 When the rotating rod 9 rotates downward, the two cleaning plates 7 will gradually open in opposite directions through the first connecting rod 16, so that the wiped corn kernels will fall back into the hammering part for collection after hammering contact; when the hammer head 6 moves upward after hammering the corn kernels, the rotating rod 9 will rotate upward along the axis of the pin shaft. During the upward rotation of the rotating rod 9, the two cleaning plates 7 will gradually shrink toward the hammer head 6 through the first connecting rod 16 until the cleaning cotton of the cleaning plate 7 fits into the outer wall of the hammer head 6. During the upward movement of the hammer head 6, it will rub against the cleaning cotton, thereby wiping off the corn kernels adhering to the outer wall of the hammer head 6, thereby completing the purpose of cleaning the outer wall of the hammer head 6, reducing the damage to the outer wall of the hammer head 6 due to scaling and corrosion, and thus extending the service life of the equipment.

[0042] It is worth mentioning that the cleaning cotton below the cleaning plate 7 is thicker than the cleaning cotton above. Since the closing action of the two cleaning plates 7 is to rotate with the axis of the pin connecting the rotating rod 9 as the center of the circle, during the closing process, the cleaning cotton above the cleaning plate 7 will first contact the outer wall of the hammer head 6. The cleaning cotton below the cleaning plate 7 is designed to be thicker so that the entire cleaning cotton can fit with the outer wall of the hammer head 6, thereby achieving a better cleaning effect.

[0043] Embodiment 2 provides a second connection portion that can open or close the cleaning plate 7 when the rotating rod 9 swings.

[0044] Furthermore, the connecting portion includes a transverse groove 28 opened on the inner wall of the outer shell 1, and the two cleaning plates 7 are slidably installed in the transverse groove 28 through a slider. A second connecting rod 25 is fixedly installed on the top of the two cleaning plates 7, and the outer walls of the two second connecting rods 25 are opened with vertical grooves 26. The outer walls of the two rotating rods 9 are fixedly connected with pins 27 that can slide in the corresponding vertical grooves 26.

[0045] See also Figure 6 When the hammer head 6 moves downward to crush the corn kernels, the sliding sleeve 4 will drive the rotating rod 9 to rotate downward along the axis of the pin shaft, thereby driving the pin 27 to slide in the vertical groove 26. Under the cooperation of the horizontal groove 28 and the slider on the outer wall of the cleaning plate 7, the two cleaning plates 7 will move in opposite directions in the horizontal direction, thereby separating the cleaning cotton on the cleaning plate 7 from the hammer head 6; when the hammer head 6 moves upward after crushing the corn kernels, the sliding sleeve 4 drives the rotating rod 9 to rotate upward along the axis of the pin shaft. Similarly to the above, the two cleaning plates 7 will approach each other in the horizontal direction, thereby making the cleaning cotton fit against the outer wall of the hammer head 6, thereby cleaning the outer wall of the hammer head 6, thereby making the equipment run more stable and reducing safety accidents caused by equipment failure.

[0046] Furthermore, an annular groove 18 is provided inside the hammer rod 3, a cylinder is fixedly connected to the top of the housing 1, a telescopic rod 8 of the cylinder penetrates the top of the housing 1 and is slidably connected to the penetration, a groove 17 is provided on the outer wall of the telescopic rod 8, a first protrusion 20 is slidably connected to the inner wall of the groove 17, and one end of the first protrusion 20 is connected to the inner wall of the groove 17 via a second spring 19;

[0047] A tension spring 5 is connected between the sliding sleeve 4 and the fixed sleeve 2 .

[0048] See also Figure 2 as well as Figure 4 A first protrusion 20 slides on the inner wall of the groove 17. When the corn kernels need to be crushed, the telescopic rod 8 is controlled by the cylinder to move downward. When the first protrusion 20 contacts the hammer rod 3, the first protrusion 20 compresses the second spring 19 and slides into the groove 17. When the first protrusion 20 slides into the annular groove 18, under the action of the second spring 19, the first protrusion 20 will be squeezed into the annular groove 18, and the telescopic rod 8 will continue to be extended downward by the cylinder. The telescopic rod 8 will move downward against the hammer rod 3, so that the hammer head 6 will hammer and crush the corn kernels.

[0049] When the hammer head 6 finishes hammering the corn kernels, the telescopic rod 8 is controlled by the cylinder to retract upward. At this time, the first protrusion 20 and the top of the annular groove 18 abut against each other and drive the hammer rod 3 to move upward. In this process, the rotating rod 9 gradually rotates upward. When the rotating rod 9 rotates to a horizontal state, the balance between the first protrusion 20 and the annular groove 18 is broken under the pulling force of the sliding rod 10, so that the first protrusion 20 shrinks into the groove 17, and then the telescopic rod 8 is separated from the hammer rod 3. At the moment when the telescopic rod 8 is separated from the hammer rod 3, the hammer rod 3 will move downward again under the action of gravity, and the sliding sleeve 4 will be pulled upward again under the action of the tension spring 5, so that the hammer head 6 is The vibration in the vertical direction will cause the rotating rod 9 to rotate continuously during the vibration process, so that the two cleaning plates 7 will swing continuously. In this process, not only can the corn crumbs on the outer wall of the hammer head 6 be further dropped by the vibration, but also the corn crumbs that are wiped off and adhered to the cleaning cotton of the cleaning plate 7 will be thrown off while the cleaning plate 7 swings, so as to complete the cleaning of the cleaning cotton and prevent the corn crumbs from continuously accumulating on the cleaning cotton, causing the surface of the cleaning cotton to gradually lose the cleaning effect, and the adhesion on the outer wall of the hammer head 6 cannot be effectively removed. Moreover, the long-term accumulation of crumbs will increase the friction between the cleaning cotton and the hammer head 6, which will not only cause the cleaning cotton to wear faster, but also may cause the hammer head 6 to be damaged.

[0050] Furthermore, one end of the sliding rod 10 extending into the cavity of the rotating rod 9 is fixedly connected with a baffle 11 , and a first spring 12 is installed between the baffle 11 and an inner wall of one side of the sliding rod 10 close to the sliding sleeve 4 .

[0051] See also Figure 3 After the telescopic rod 8 is separated from the hammer rod 3, when the hammer rod 3 vibrates up and down, it will drive the baffle 11 to slide inside the sealing chamber 13 through the sliding rod 10, and then squeeze the first spring 12, so that the first spring 12 produces an elastic force on the baffle 11, so that the hammer rod 3 swings with a larger amplitude, and more effectively makes the corn kernels adhered to the cleaning cotton of the cleaning plate 7 fall into the hammer part, thereby increasing the service life of the cleaning cotton and saving resources.

[0052] Furthermore, a sealed chamber 13 is formed in the space between the baffle 11 and the inner wall of the sliding rod 10 on the side away from the sliding sleeve 4, and an air inlet pipe 14 and an air outlet pipe 15 are fixedly connected to the outer wall of the rotating rod 9. The air inlet pipe 14 connects the sealed chamber 13 with the external water tank, and the air outlet pipe 15 connects the rotating rod 9 with the cleaning cotton inside the cleaning plate 7, and a one-way valve is installed in both the air inlet pipe 14 and the air outlet pipe 15.

[0053] From the above, it can be seen that while the rotating rod 9 rotates, the baffle 11 will slide inside the sealed chamber 13. When the sealed chamber 13 moves toward the direction close to the sliding sleeve 4, the water in the external water tank will be pumped into the sealed chamber 13 through the air inlet pipe 14. When the sealed chamber 13 moves away from the sliding sleeve 4, the water in the sealed chamber 13 will be injected into the cleaning plate 7 through the air outlet pipe 15, so that the cleaning plate 7 remains moist. The moist cleaning cotton can effectively reduce the generation of static electricity, prevent corn kernels from being adsorbed on the hammer head 6 or the cleaning cotton due to static electricity, and can reduce the friction between the hammer head 6 and the cleaning cotton, thereby reducing wear and extending the service life of the equipment and the cleaning cotton.

[0054] It is worth mentioning that while the hammer head 6 vibrates up and down, the baffle 11 will also reciprocate in the sealed chamber 13. In this process, the water in the external water tank will also be injected into the cleaning cotton to retain moisture for the cleaning cotton, so that the cleaning cotton remains moist at all times.

[0055] Furthermore, an internal thread groove 21 is formed on the inner wall of the fixing sleeve 2 , and the internal thread groove 21 is an oblique groove when expanded. A second protrusion 29 that can slide in the internal thread groove 21 is fixedly connected to the outer wall of the hammer rod 3 .

[0056] See also Figure 5 When the hammer rod 3 moves downward against the hammer rod 3, the hammer rod 3 drives the hammer head 6 to rotate under the cooperation of the second protrusion 29 and the internal thread groove 21. The rotating hammer head 6 can evenly distribute the impact force so that each corn kernel can be subjected to similar impact and friction, thereby achieving a more uniform crushing effect. In addition, the centrifugal force can be used to throw the adhered broken grains off the surface of the hammer head 6 during the rotation process, which has a certain self-cleaning effect and reduces the cleaning and maintenance work of the equipment.

[0057] Similarly, the hammer head 6 will also rotate during the upward movement. When the cleaning cotton of the cleaning plate 7 is in contact with the hammer head 6, the rotation of the hammer head 6 can enable the cleaning cotton to cover the entire surface of the hammer head 6, ensuring that every part is effectively cleaned and more adhesions are removed.

[0058] Furthermore, an air storage ring 22 is fixedly connected to the outer wall of the sliding sleeve 4 , the air storage ring 22 is connected to an external hot air dryer, and a plurality of nozzles 23 are fixedly installed at the bottom of the air storage ring 22 , and the nozzles 23 are communicated with the inside of the air storage ring 22 .

[0059] See also Figure 2In the process of the hammer head 6 continuously hammering and crushing the corn kernels, hot air is blown into the air storage ring 22 through an external hot air dryer, and then blown to the hammer head 6 through the nozzle 23, further blowing off the corn crumbs adhering to the surface of the hammer head 6, and also drying the corn kernels in the hammer part. The dried corn kernels are not easy to adhere to the hammer head 6 or other parts of the equipment during the crushing process, thereby improving the crushing efficiency and the stability of the equipment operation.

[0060] It is worth mentioning that when the two cleaning plates 7 are opened, a trumpet shape is formed, so that the hot air blown out from the nozzle 23 flows along the surface of the hammer head 6, thereby further improving the cleaning effect on the hammer head 6.

[0061] Furthermore, the hammering part includes a striking platform 24 , which is hemispherical and has a plurality of sieve holes formed on its inner wall.

[0062] See also Figure 7 When the corn kernels are crushed, the corn kernels are placed on the top of the striking platform 24. When the hammer head 6 moves downward, it will cooperate with the striking platform 24 to crush the corn kernels. The crushed corn kernels will leave through the sieve holes for subsequent processing.

[0063] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
