Description

Technical Field

[0001] The invention relates to the technical field of animal feed processing machinery, and in particular to a mixing device for cattle feed processing. Background Art

[0002] Beef is rich in nutrients such as protein and amino acids. Its composition is closer to human needs than pork. It can improve the body's disease resistance and is particularly suitable for people who are growing and developing, as well as those who are recovering from surgery or illness, in terms of replenishing blood loss and repairing tissues. Therefore, beef is widely loved by people, and the number of cattle farmers is gradually increasing. In the process of raising cattle, farmers usually add feed to the cattle in order to make the cattle absorb more nutrients and shorten the fattening period. Feed refers to the general term for food for all animals raised by people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry.

[0003] In the process of animal feed production and processing, the feed raw materials need to be fully stirred to promote sufficient mixing between the feed raw materials. The current feed stirring and mixing device usually includes a stirring drum, a feed box is provided on the upper side of the stirring drum, and stirring blades are provided in the stirring drum. The workers stir the stirring blades to achieve mixing and stirring of the feed. However, there are still some shortcomings in this way of stirring: as the stirring time increases, the stirring force of the workers gradually weakens, resulting in uneven force applied by the workers during the stirring process, and the mixing degree of the stirring drum from the inside to the outside is uneven, resulting in insufficient stirring of the raw materials. Summary of the invention

[0004] The present invention aims to provide a mixing device for cattle feed processing with more complete stirring.

[0005] To achieve the above-mentioned purpose, the technical scheme of the present invention is: a mixing device for cattle feed processing, comprising a frame and an operating box, the operating box is fixed on the frame, a feed box is also fixed on the frame, a forward and reverse motor is arranged above the operating box, a slide plate is vertically slidably connected in the operating box, a side wall of the operating box is provided with a slide groove slidably matched with the slide plate, first slide blocks are arranged on the lower sides of both ends of the slide plate, a connecting rod is fixedly connected between the first slide block and the slide plate, a feed port is arranged on the operating box, a conduit is connected between the feed box and the feed port, the feed port can be blocked by the first slide block, a support plate is arranged below the slide plate, a primary stirring chamber is arranged above the support plate, a secondary stirring chamber is arranged below the support plate, the cross-sectional area of ​​the primary stirring chamber is larger than the cross-sectional area of ​​the secondary stirring chamber, a bidirectional lead screw is coaxially connected to the output shaft of the forward and reverse motor, through holes are arranged on the slide plate and the support plate, nuts are arranged at both ends of the bidirectional lead screw, the bidirectional lead screw passes through the slide plate and the support plate and extends to the bottom of the support plate, the nut is fixedly connected in the through holes of the slide plate and the support plate, and a plurality of stirring blades are arranged on the bidirectional lead screw.

[0006] Beneficial effects of the present invention:

[0007] (1) Pour the feed into the feed box from the feed inlet, and the feed accumulates in the primary stirring chamber. When the motor output shaft drives the stirring blade to rotate, the stirring blade mixes the feed in the primary stirring chamber, and the motor output shaft rotates while driving the slide plate upward through the bidirectional lead screw. Since the cross-sectional area of ​​the primary stirring chamber is larger than that of the secondary stirring chamber, after the slide plate slides upward, the primary stirring chamber and the secondary stirring chamber will be connected, so that the feed inside the primary stirring chamber falls into the secondary stirring chamber. Since the bottom of the bidirectional lead screw is rotatably connected to the fixed plate in the secondary stirring chamber, the stirring blade in the secondary stirring chamber will further mix the feed that is not evenly mixed in the primary stirring chamber to achieve more complete mixing.

[0008] (2) In this scheme, while the bidirectional lead screw rotates, the first slider and the second slider are driven to slide vertically by the slide plate. When the first slider slides downward, the first slider opens the feed inlet, and the support plate is just in place at this time to receive the feed. When the first slider slides upward, the first slider blocks the feed inlet, and the support plate slides upward with the bidirectional lead screw at this time. The feed that has been stirred for the first time falls into the secondary stirring chamber, and the feed inlet will not be mistakenly fed with feed.

[0009] Furthermore, both ends of the skateboard extend through the operating box to the outside of the operating box, and the left and right ends of the skateboard extending to the outside of the operating box are fixedly connected with a vertical first spur rack, the frame is fixedly connected with a water tank, the operating box is provided with a water inlet, a water pipe is connected between the water tank and the water inlet, a first outer gear ring and a first rotary valve are coaxially provided on the water pipe, the first rotary valve is connected to the first outer gear ring, a third gear is provided on the frame, the first spur rack is meshed with the third gear, and the third gear is meshed with the first outer gear ring.

[0010] Beneficial effect: The vertical upward or downward movement of the first spur rack is controlled by moving the slide up or down, and the rotation of the first rotary valve is controlled by the rotation of the third gear. When the first rotary valve is changed from the closed position to the open position, the water in the water tank enters the primary mixing chamber.

[0011] Furthermore, an air box is provided on the right side of the operating box, a vortex tube is provided below the air box, an air guide tube is connected between the air box and the vortex tube, the cold air end of the vortex tube is connected with a first air pipe, the first air pipe is connected with the right side wall of the operating box, the connection point between the first air pipe and the right side wall of the operating box is opposite to the stirring blades in the secondary stirring chamber, the hot air end of the vortex tube is connected with a second air pipe, the second air pipe is connected with the right wall of the feed box, a piston plate is horizontally slidably connected in the feed box, and a second spring is fixed between the side of the piston plate facing the operating box and the side wall of the feed box.

[0012] Beneficial effect: The cold air generated by the vortex tube enters the secondary mixing chamber of the operating box through the first air guide pipe, and the cold air cools the mixing blades in the secondary mixing chamber, preventing the mixing blades from overheating and damaging the equipment after friction with the feed.

[0013] Furthermore, the bidirectional lead screw is coaxially connected to a first gear at one end away from the forward and reverse motor, the first gear is meshed with a second spur rack, the second spur rack extends horizontally to the right through the operating box to the outside of the operating box, a second rotary valve is provided on the air duct, the second rotary valve is connected to a second outer gear ring, the second outer gear ring is meshed with a second gear, the second gear is arranged on the frame, and the second gear is meshed with the second spur rack.

[0014] Beneficial effect: When the forward and reverse motors are started, the first gear, the second spur rack, the second gear, the outer gear ring and the second rotary valve cooperate with each other, so that the gas in the air box can enter the vortex tube through the air guide pipe only when the forward and reverse motors are started, thereby saving working costs.

[0015] Furthermore, a baffle is provided below the support plate, and the baffle is located below the first gear. The right end of the baffle is hinged to the right inner wall of the operating box, and a first telescopic rod is provided between the left end of the baffle and the left end of the support plate. The top of the first telescopic rod is slidably connected to the bottom of the support plate, and the bottom of the first telescopic rod is hinged to the baffle. A second telescopic rod is provided between the bottom of the baffle and the left side wall of the operating box, the top of the second telescopic rod is slidably connected to the bottom of the baffle, and the bottom of the second telescopic rod is ball-jointed to the left side wall of the operating box, and an arc spring is fixedly connected between the baffle and the right side wall of the operating box.

[0016] Beneficial effect: The thrust of the arc spring on the baffle is greater than the pressure on the baffle when the first telescopic rod is compressed. When a certain volume of feed is accumulated on the baffle, the sum of the gravity of the feed and the pressure of the first telescopic rod is greater than the thrust of the arc spring, so that the baffle is tilted, and the baffle drives the second telescopic rod to slide to the right along the bottom of the baffle. According to the triangle law, the length of the inclined hypotenuse is greater than the horizontal vertical side, so when the baffle is tilted, there is a gap between the baffle and the left side wall of the operating box, and the feed accumulated on the baffle is discharged from the gap. When the feed accumulated on the baffle is reduced and the first telescopic rod moves upward with the support plate, the baffle is reset under the action of the arc spring, and the baffle moves up to drive the top of the second telescopic rod to slide to the left along the bottom of the baffle.

[0017] Furthermore, a limit block is provided on the left inner wall of the operation box, and the limit block is located above the baffle and abuts against the baffle. An elastic airbag is provided on the right inner wall of the operation box, and the elastic airbag is located below the baffle and abuts against the baffle.

[0018] Beneficial effect: The elastic airbag provides a vertical upward support for the baffle, preventing the feed from exerting excessive pressure on the connection between the first telescopic rod and the baffle when the baffle tilts downward, causing the connection between the first telescopic rod and the baffle to break. At the same time, the limit block can exert a downward pressure on the left end of the baffle to prevent the baffle from tilting upward under the pull of the first telescopic rod.

[0019] Furthermore, the bottom of the operating box is set to be open, and a horizontal pull plate is slidably connected to the opening, a first spring is fixedly connected between the pull plate and the right side wall of the operating box, a pressure platform is provided on the left side of the pull plate, the pressure platform is located above the frame, a reset spring is fixedly connected between the pressure platform and the frame, a first fixed pulley is provided between the pressure platform and the pull plate, a pull rope is welded on the pull plate, the pull rope is connected to the bottom of the pressure platform through the first fixed pulley, and a receiving groove is provided under the pull plate.

[0020] Beneficial effect: After being stirred, the feed slides off the baffle and accumulates on the pull plate. When collecting the feed, downward pressure is applied to the pressure platform, so that the pull rope, under the action of the first fixed pulley, pulls the pull plate to slide horizontally to the left, allowing the feed to fall into the receiving trough. Compared with not setting up a pull plate, if the baffle happens to tilt when the receiving trough is transferred, it will cause waste of feed. After adding the pull plate, the feed can be received by actively controlling the pressure platform. BRIEF DESCRIPTION OF THE DRAWINGS

Through holes are provided on the slide plate 5 and the support plate 11, and the bidirectional lead screw 4 is rotatably connected to the slide plate 5 and the support plate 11 and extends into the secondary stirring chamber. Through holes are respectively provided on the slide plate 5 and the support plate 11, and nuts are fixedly connected in the through holes. The nut and the bidirectional lead screw form a threaded pair and the threaded pair does not meet the self-locking condition.

The inclined plate 6 is higher than the water inlet and is welded to the inner wall of the operation box 1. The feed is guided by the inclined plate 6 so that the feed can better contact the stirring blade 10 through the inclined plate 6, preventing the feed from entering the primary stirring chamber and accumulating in a place far away from the stirring blade 10.

[0031] The end of the bidirectional lead screw 4 away from the forward and reverse motor 2 is coaxially connected to the first gear 12, and a horizontal second spur rack 13 is provided in the secondary stirring chamber. The second spur rack 13 includes a smooth section and toothed sections located on both sides of the smooth section, and the first gear 12 is meshed with the second spur rack 13. An air box 18 is provided on the right side of the secondary stirring chamber. The air box 18 is fixed on the frame. The bottom of the air box 18 is connected to an air duct, and a second rotary valve 16 is provided on the air duct. The second rotary valve 16 is coaxially provided with a second outer gear ring 15, and the second outer gear ring 15 is meshed with a second gear 14, and the second gear 14 is rotatably connected to the frame. The second spur rack 13 is horizontally slidably connected to the operating box 1 and extends to the outside of the operating box 1. The second spur rack 13 is meshed with the second gear 14. A vortex tube is provided below the air box 18, and the vortex tube is fixed on the frame. The air box 18 is connected to the air inlet end of the vortex tube through the air duct. The cold air end of the vortex tube is connected with a first air pipe, and the hot air end of the vortex tube is connected with a second air pipe.

[0032] The first air pipe is connected to the right side wall of the operating box 1, and the connection point is opposite to the stirring blade 10 in the secondary stirring chamber. The second air pipe is connected to the feed box 3. The second air pipe is a Y-shaped pipe, and the Y-shaped pipe includes a first branch pipe and a second branch pipe. The first branch pipe is connected to the feed box 3 on the left side of the operating box 1, and the second branch pipe is connected to the feed box 3 on the right side of the operating box 1. A piston plate 22 is horizontally slidably connected in the feed box 3. A second spring is welded on the side wall of the feed box 3 away from the connection point between the second air pipe and the feed box 3, and the second spring is welded to the piston plate 22.

[0033] A stop block is provided on the left inner wall of the secondary stirring chamber, and a first telescopic rod 20 is provided between the left end of the support plate 11 and the left end of the baffle 19. The right end of the baffle 19 is hinged to the inner wall of the operation box 1, and an elastic airbag 21 is provided below the right side of the baffle 19. The elastic airbag 21 is filled with gas, and the elastic airbag 21 is fixedly connected to the inner wall of the operation box 1, and the elastic airbag 21 abuts against the baffle 19. A second telescopic rod is provided between the left end of the bottom of the baffle 19 and the left side wall of the operation box 1, and the bottom of the second telescopic rod is spherically hinged to the left side wall of the operation box 1, and the top of the second telescopic rod is horizontally slidably connected to the bottom of the baffle 19. An arc spring is fixedly connected between the bottom of the baffle 19 and the right side wall of the operation box 1, and the elastic force of the arc spring is greater than the thrust of the first telescopic rod 20 on the baffle 19. The first telescopic rod and the second telescopic rod can keep the baffle 19 horizontal when the baffle 19 is not under force, and when the baffle 19 is tilted under pressure, the top of the second telescopic rod slides along the bottom of the baffle 19 toward the right wall of the operation box 1. It can be known from the triangle theorem that the length of the hypotenuse is greater than the length of the vertical side. Since the length of the baffle 19 is fixed, when the baffle 19 is tilted, there is a gap between the baffle 19 and the left side wall of the operating box 1, so that the feed on the baffle 19 can fall down from the gap. When the first telescopic rod moves upward, the first telescopic rod pulls the baffle 19 upward, so that the top of the second telescopic rod slides along the bottom of the baffle 19 toward the left side wall of the operating box 1. When the top surface of the baffle 19 contacts the limit block, the limit block keeps the baffle horizontal. The bottom of the operating box 1 is set as an opening, and a horizontal pull plate 25 is provided on the opening. An inclined block is provided between the pull plate 25 and the baffle 19. The left side wall of the inclined block is welded to the left side plate of the operating box. A first spring is connected between the pull plate 25 and the right side wall of the operating box. A receiving slot 26 is provided directly below the operating box 1. Figure 1 As shown, a pressure platform 23 is provided on the left side of the receiving groove 26, a return spring is welded at the bottom of the pressure platform 23, and the end of the return spring away from the pressure platform 23 is welded to the frame, a first fixed pulley 24 is provided between the pressure platform 23 and the operating box 1, and a pull rope wound around the first fixed pulley 24 is connected between the pressure platform 23 and the pull plate 25. When the pressure platform 23 moves downward, the pull plate 25 is pulled horizontally to the left by the pull rope, so that the cattle feed accumulated between the pull plate 25 and the baffle 19 falls into the receiving groove 26.

[0034] The specific implementation process is as follows:

[0035] During the production process, by starting the forward and reverse motor 2, when the motor rotates forward, the nut is driven to rotate through the bidirectional lead screw 4, so that the slide plate 5 and the support plate 11 move downward. The downward movement of the slide plate 5 drives the first slider 17 to slide downward, so that the feed port is not blocked, so that the feed in the feed box 3 can fall into the primary stirring chamber through the conduit. And the bidirectional lead screw 4 drives the stirring blade 10 to mix and stir the feed. While the slide plate 5 moves downward, it drives the first straight rack 8 to move downward, and drives the third gear 27 to rotate through the first straight rack 8, so that the first outer gear ring 28 is driven to rotate through the third gear 27, so that the first rotary valve 9 is converted from the closed position to the open position, and the valve is opened, thereby achieving the mixing of feed and water. This water adding process does not require manual operation, which reduces the amount of manual labor.

[0036] When the forward and reverse motor 2 reverses, the nut is driven to rotate by the bidirectional lead screw 4, so that the slide plate 5 and the support plate 11 move upward. Therefore, the first slide block 17 is driven by the connecting rod to slide upward under the action of the slide plate 5 to cover the feed port. At the same time, the slide plate 5 drives the first spur rack 8 to move upward, so that the first spur rack 8 drives the third gear 27 to rotate, and the first outer gear ring 28 rotates to change the first rotary valve 9 from the open position to the closed position, thereby realizing the closing of the valve.

[0037] When the forward and reverse motor 2 reverses, the support plate 11 moves upward under the action of the bidirectional lead screw 4. Since the cross-sectional area of ​​the primary stirring chamber is larger than that of the secondary stirring chamber, the feed in the primary stirring chamber will fall into the secondary stirring chamber. Since the stirring blades 10 in the secondary stirring chamber rotate along with the rotation of the bidirectional lead screw 4, the feed that falls into the secondary stirring chamber can continue to be stirred, so that the feed that was not mixed evenly in the primary stirring chamber before can be further mixed. And while the slide plate 5 moves upward, the baffle 19 is pulled upward by the first telescopic rod 20. Since a limit block is provided in the secondary stirring chamber, the baffle 19 is limited so that the baffle 19 is horizontal when it slides upward and contacts the limit block. This prevents the baffle 19 from continuing to slide upward under the drive of the first telescopic rod, causing the baffle 19 to tilt. When the first telescopic rod is compressed downward with the support plate, the baffle plate remains horizontal because the thrust of the arc spring is greater than the pressure of the first telescopic rod on the baffle plate. When a certain volume of feed is piled on the baffle plate, the sum of the gravity of the feed and the pressure of the first telescopic rod on the baffle plate is greater than the thrust of the arc spring, thereby pushing the baffle plate to tilt. Since the length of the inclined hypotenuse is greater than the horizontal and vertical sides, and the length of the baffle plate is the same, a gap will appear between the baffle plate and the left side wall of the operating box when the baffle plate is tilted, causing the feed piled on the baffle plate to fall through the gap.

[0038] When the forward and reverse motor 2 is turned on, the first gear 12 rotates with the two-way screw 4, thereby driving the second gear 14 to rotate through the second spur rack 13, thereby driving the second outer gear ring 15 to rotate through the second gear 14, thereby driving the second rotary valve 16 from the closed position to the open position through the second outer gear ring 15, so that the gas in the air box 18 enters the turbine tube, and the cold air generated by the vortex tube flows into the secondary stirring chamber through the first air pipe to cool the stirring blade 10. The hot air generated by the vortex tube is transported to the feed box 3 through the second air pipe, and the feed delivery rate is increased by pushing the piston plate 22.

[0039] A downward pressure is applied to the pressure platform 23 to move the pressure platform 23 downward, so that the pull plate 25 is pulled out laterally through the pull rope on the first fixed pulley 24, so that the feed accumulated on the pull plate 25 falls into the receiving groove 26.

[0040] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, which should also be regarded as the protection scope of the present invention, and will not affect the effect of the implementation of the present invention and the practicality of the patent. The technology, shape, and structural parts omitted in the present invention are all well-known technologies.
