Description

Technical Field

[0001] The invention relates to the technical field of feed mixing equipment, and in particular to a vertical livestock feed mixer. Background Art

[0002] Animal feed is a general term for the food of all artificially raised animals. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc. In animal husbandry, in addition to grass, mixed feed made from a mixture of various raw materials is the most common animal feed and the animal feed with the largest consumption. The breeders use feed mixers to mix and stir various raw materials evenly to obtain more economical feed that is suitable for the growth of the farmed animals, thereby maximizing the breeding profit. In the production of mixed feed, in addition to selecting suitable raw materials, stirring the mixed feed is also particularly important. Through sufficient and uniform stirring, the nutrients are evenly dispersed in the feed, and the nutrients added in the feed can be fully absorbed by the farmed animals, thereby achieving the breeding expectations. Therefore, it is necessary to invent a feed mixer that can promote the uniform stirring of animal feed;

[0003] For example, a feed mixing equipment for animal husbandry with application number 202010211805.6 comprises a tank body, an annular mounting plate is fixedly connected to the inner wall of the tank body, a mixing tank is fixedly mounted inside the annular mounting plate, a material tank is arranged above the tank body, two support rods are fixedly connected to the lower end of the material tank, the support rods are fixedly connected to the outer wall of the tank body, a plurality of raw material cavities are arranged inside the material tank, a conical feed pipe is connected to the lower end of the material tank, and a feeding mechanism for conveying different feeds is arranged inside the interface between the material tank and the conical feed pipe. The present invention has a reasonable structure and is easy to operate. It can realize automatic and continuous feeding of different kinds of feeds, preliminarily mix them, and then pass them into the mixing tank for stirring, which saves time and labor and effectively shortens the stirring time. In addition, compressed gas can be introduced into the feed during the stirring process to improve the mixing efficiency, and at the same time, air is filled into the feed, and the gaps between the feeds become larger, which is more conducive to stirring and mixing;

[0004] Although this patent can mix the feed evenly, the material added during use must be a dry powder raw material with good fluidity. In the rainy season and in some mountainous areas with relatively humid air, since most feed raw materials are packaged in woven bags, they often absorb moisture in the air and cause the raw materials to often form lumps. When the equipment is used with raw materials containing lumps, the lumps are easy to block the feed hole, making it impossible for the equipment to feed and mix normally, thereby causing uneven distribution of components in the mixture. Summary of the invention

[0005] The invention provides a vertical livestock feed mixer to solve the technical problem of uneven feed mixing and stirring due to agglomeration during feed stirring.

[0006] A vertical livestock feed mixer of the present invention adopts the following technical scheme: a vertical livestock feed mixer comprises a mixing barrel for mixing and stirring feed, a support frame for supporting the mixing barrel, a feeding barrel is fixedly connected to the center position of the lower end surface of the mixing barrel, a feeding groove is welded on the outer wall of the feeding barrel, and the feeding groove is connected with the inside of the feeding barrel, a discharge port is welded on the conical side wall of the mixing barrel, the center positions of the mixing barrel and the feeding barrel are rotated together with a central auger, the upper end surface of the mixing barrel is equipped with a power mechanism that drives the central auger to rotate, and the inside of the mixing barrel A lifting cylinder is provided which is sleeved on the outside of the central auger and is fixed to the inner wall of the mixing barrel through a supporting rod. It also includes a fixed sleeve which is sleeved between the upper end of the rotating blade of the central auger and the upper end surface of the inner part of the mixing barrel, and one end of the fixed sleeve is fixed to the upper end surface of the mixing barrel. A material blocking plate assembly is slidably fitted on the outer wall of the fixed sleeve, and a plurality of fixed rods are circumferentially fixedly welded to the material blocking plate assembly. A plurality of fan-shaped crushing plate assemblies for impact crushing are circumferentially provided on the outside of the fixed sleeve and below the material blocking plate assembly, and the crushing plate assembly is hinged to the other end of the fixed rod.

[0007] Furthermore, the material blocking plate assembly includes a sliding material blocking plate that is slidably fitted on the outer wall of the fixed sleeve, an annular fixed tube is welded to the upper end surface of the sliding material blocking plate, the annular fixed tube is fixedly welded to one end of multiple fixed rods, and a compression spring is arranged between the sliding material blocking plate and the upper end surface inside the mixing barrel.

[0008] Furthermore, the lower end surface of the sliding material blocking plate is an upwardly inclined curved surface, and when the material hits the lower end surface of the sliding material blocking plate, it scatters around along the curved surface.

[0009] Furthermore, a semi-enclosed baffle plate for intermittent feeding is welded on the outer wall of the central auger and below the lifting cylinder. During the rotation of the central auger, the amount of feed entering the central auger through the bottom of the lifting cylinder changes periodically under the action of the baffle plate.

[0010] Furthermore, the crushing plate assembly includes a hinge joint fixedly welded to one end of the fixed rod, a hinge rod is rotatably engaged on the hinge joint, a tension spring is arranged between the hinge rod and the fixed rod, a first fan-shaped connecting plate is fixedly welded below the hinge rod, a plurality of arc rods are circumferentially welded on the first fan-shaped connecting plate, a second fan-shaped connecting plate is welded together on the side of the plurality of arc rods away from the first fan-shaped connecting plate, and the second fan-shaped connecting plate, the first fan-shaped connecting plate and the arc rods are welded into an integral fan-shaped plate, gaps are left between the plurality of arc rods for powder to pass through, the hinge point is arranged at the first fan-shaped connecting plate, and the front end of the fan-shaped plate welded into one body tends to flip downward under the action of gravity, and the front end is kept in an upward tilted state under the action of the tension spring.

[0011] Furthermore, a triangular extrusion head is welded on the outer wall of the arc rod and the outer side of the first fan-shaped connecting plate, and a V-shaped space is formed between adjacent triangular extrusion heads.

[0012] Furthermore, a fan-shaped fixing block is arranged above the triangular extrusion head, and the fan-shaped fixing block is fixedly welded to the inner wall of the mixing barrel, a plurality of extrusion teeth are welded to the lower end surface of the fan-shaped fixing block, and the extrusion teeth and the V-shaped space form a matching structure.

[0014] The beneficial effects of the present invention are as follows: the baffle plate assembly, the crushing plate assembly and the center auger are arranged in the present invention. The amount of feed entering the center auger during the rotation of the center auger changes periodically under the action of the baffle plate. When the sliding baffle plate is pushed up, the front end of the fan plate is deflected downward, and the tension spring is stretched. When the sliding baffle plate moves to a certain height, the impact force of the feed is reduced and the upward movement speed is slowed down. The tension spring rebounds, pulling the front end of the fan plate to deflect upward, thereby colliding head-on with the falling feed, and the discharged agglomerated feed is slapped and crushed. In this process, the periodic discharging can give the mechanical mechanism enough reaction time, thereby greatly increasing the probability of the fan plate rebounding and hitting the feed, and enhancing the impact and crushing effect. In this way, the mixing equipment can be made more applicable, meet the feed mixing operation when the feed is agglomerated in harsh environments, and make the feed mixed more fully and evenly.

DETAILED DESCRIPTION

[0024] 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.

[0025] An embodiment of a vertical livestock feed mixer of the present invention is as follows Figures 1 to 7As shown, it includes a mixing barrel 1 for mixing and stirring feed, a support frame 3 for supporting the mixing barrel 1, a feeding barrel 2 is fixedly connected to the center of the lower end surface of the mixing barrel 1, a feeding groove 7 is welded on the outer wall of the feeding barrel 2, and the feeding groove 7 is connected to the inside of the feeding barrel 2, a discharge port 8 is welded on the conical side wall of the mixing barrel 1, and a central auger 9 is rotated together at the center of the mixing barrel 1 and the feeding barrel 2, and a power mechanism that drives the central auger 9 to rotate is installed on the upper end surface of the mixing barrel 1, and a lifting barrel 1 connected to the outside of the central auger 9 is arranged inside the mixing barrel 1 0, and the lifting cylinder 10 is fixed on the inner wall of the mixing barrel 1 through the support rod 12, and also includes a fixed sleeve 17 sleeved between the upper end of the rotating blade of the central auger 9 and the upper end surface of the inner part of the mixing barrel 1, and one end of the fixed sleeve 17 is fixed to the upper end surface of the mixing barrel 1, and a material blocking plate assembly is slidably matched on the outer wall of the fixed sleeve 17, and a plurality of fixed rods 15 are circumferentially fixedly welded to the material blocking plate assembly, and a plurality of fan-shaped crushing plate assemblies for impact crushing are circumferentially arranged on the outer side of the fixed sleeve 17 and below the material blocking plate assembly, and the crushing plate assembly is hinged to the other end of the fixed rod 15;

[0026] During specific operation, the power mechanism drives the central auger 9 to rotate, and the feed raw materials are poured into the upper barrel 2 from the feeding trough 7, and move upward under the push of the central auger 9. After all the raw materials are added, the feed inlet of the upper barrel 2 is blocked with a blocking tool for stirring. During stirring, the feed enters the lifting barrel 10 from the lower end of the lifting barrel 10, is pushed to the top of the lifting barrel 10 by the central auger 9, and then scattered to the surroundings. The scattered feed continues to move to the bottom of the conical barrel and is repeatedly pushed up and scattered by the central auger 9, thereby achieving the purpose of feed stirring;

[0027] In this process, when the feed is pushed up to the top along the lifting cylinder 10, it pushes the material blocking plate assembly that is slidably fitted on the fixed sleeve 17, causing the material blocking plate assembly to slide up and down, thereby driving the crushing plate assembly hinged at the other end of the fixed rod 15 to vibrate through the fixed rod 15, thereby colliding with the falling and scattered feed, and the feed falls from the gap. The agglomerated feed is broken and scattered during the collision and falls from the gap.

[0028] As an embodiment of the present invention, Figure 5 and Figure 7 As shown, a semi-enclosed baffle plate 11 for intermittent feeding is welded on the outer wall of the central auger 9 and below the lifting cylinder 10. During the rotation of the central auger 9, the amount of feed entering the central auger 9 through the bottom of the lifting cylinder 10 changes periodically under the action of the baffle plate 11.

[0029] During specific operation, when the rotating blades of the central auger 9 below the lifting cylinder 10 rotate one circle, the feed between the blades of the central auger 9 is pushed up by one pitch, and the feed at this location is filled with the half of the material opposite to the baffle plate 11 under the action of the baffle plate 11, while the material on the other half is loose. As a result, when the central auger 9 pushes the feed to the top of the lifting cylinder 10, the material delivered by the central auger 9 when it rotates one circle is more in half a circle and less in the other half, thereby causing the feed to be subjected to a periodically changing impact force on the baffle plate assembly to increase the reciprocating sliding distance of the baffle plate assembly.

[0030] As an embodiment of the present invention, Figure 3-Figure 6 As shown, the material blocking plate assembly includes a sliding material blocking plate 13 that is slidably matched on the outer wall of the fixed sleeve 17, an annular fixed tube 14 is welded to the upper end surface of the sliding material blocking plate 13, and the annular fixed tube 14 is fixedly welded to one end of a plurality of fixed rods 15, a compression spring 16 is arranged between the sliding material blocking plate 13 and the upper end surface inside the mixing barrel 1, and the lower end surface of the sliding material blocking plate 13 is an upwardly inclined curved surface, and when the material hits the lower end surface of the sliding material blocking plate 13, it scatters outward along the curved surface;

[0031] The crushing plate assembly includes a hinge joint 18 fixedly welded to one end of a fixed rod 15, a hinge rod 20 is rotatably matched on the hinge joint 18, a tension spring 19 is arranged between the hinge rod 20 and the fixed rod 15, a first fan-shaped connecting plate 25 is fixedly welded below the hinge rod 20, a plurality of arc-shaped rods 23 are circumferentially welded on the first fan-shaped connecting plate 25, a second fan-shaped connecting plate 26 is welded together on the side of the plurality of arc-shaped rods 23 away from the first fan-shaped connecting plate 25, and the second fan-shaped connecting plate 26, the first fan-shaped connecting plate 25 and the arc-shaped rods 23 are welded to form an integral fan-shaped plate, gaps are left between the plurality of arc-shaped rods 23 for powder to pass through, and a hinge point is arranged at the first fan-shaped connecting plate 25, and the front end of the fan-shaped plate welded into one body has a tendency to flip downward under the action of gravity, and the front end is kept in an upward tilted state under the action of the tension spring 19;

[0032] During specific operation, when the feed is pushed out, the sliding blocking plate 13 slides back and forth under the squeezing of the feed and the support of the compression spring 16. When the feed overflows and pushes the sliding blocking plate 13 to rise, the sliding blocking plate 13 pulls the hinge head 18 upward through the fixed rod 15, and the fan-shaped plate is subjected to instantaneous tension at the rear end under the action of the gravity of the front end, and the front end deflects downward relative to the fixed rod 15, and the tension spring 19 is stretched. When the sliding blocking plate 13 moves to a certain height, the impact force of the feed is reduced and the upward movement speed is slowed down, the tension spring 19 rebounds, and the front end of the fan-shaped plate deflects upward, thereby colliding head-on with the falling feed, and the discharged agglomerated feed is slapped and crushed. In this process, periodic discharging can give the mechanical mechanism enough reaction time, thereby greatly increasing the probability of the fan-shaped plate rebounding and hitting the feed, thereby enhancing the impact and crushing effect.

[0033] As an embodiment of the present invention, Figure 6 As shown, a triangular extrusion head 24 is welded on the outer wall of the arc rod 23 and the outer side of the first fan-shaped connecting plate 25, and a V-shaped space is formed between adjacent triangular extrusion heads 24, a fan-shaped fixing block 21 is arranged above the triangular extrusion head 24, and the fan-shaped fixing block 21 is fixedly welded on the inner wall of the mixing barrel 1, and a plurality of extrusion teeth 22 are welded on the lower end surface of the fan-shaped fixing block 21, and the extrusion teeth 22 and the V-shaped space are a matching structure;

[0034] During specific operation, when the feed lumps are hard and are not broken by tapping, they slide down to the V-shaped space of the triangular extrusion head 24 bracket under the shaking of the fan-shaped plate. When the sliding material blocking plate 13 moves up or the feed hits the front end of the fan-shaped plate, the triangular extrusion head 24 moves up and cooperates with the extrusion teeth 22 to crush the lumps. The V-shaped structure is convenient for the feed lumps to slide into the mixing barrel 1 after being crushed.

[0035] The power mechanism includes a stirring wheel 5 rotatably fitted at the center of the upper end surface of the stirring barrel 1 , a motor welding frame 6 is welded on the top outer wall of the stirring barrel 1 , a motor 4 is mounted on the motor welding frame 6 , and the motor 4 is connected to the stirring wheel 5 .

[0036] In summary, the power mechanism drives the central auger 9 to rotate, and the feed raw materials are poured into the upper barrel 2 from the feeding trough 7, and move upward under the push of the central auger 9. After all the raw materials are added, the feed inlet of the upper barrel 2 is blocked with a blocking tool for stirring. During stirring, the mixed feed 27 enters the lifting barrel 10 from the lower end of the lifting barrel 10, is pushed to the top of the lifting barrel 10 by the central auger 9, and then scattered to the surroundings. The scattered feed continues to move to the bottom of the conical barrel and is repeatedly pushed up and scattered by the central auger 9, thereby achieving the purpose of feed stirring.

[0037] During the rotation of the central auger 9, the amount of feed entering the central auger 9 through the bottom of the lifting cylinder 10 changes periodically under the action of the baffle plate 11. When the feed overflows and pushes the sliding baffle plate 13 to rise, the sliding baffle plate 13 pulls the hinge head 18 upward through the fixed rod 15. Under the action of the gravity of the front end, the rear end of the fan-shaped plate is subjected to an instantaneous pulling force, and the front end deflects downward relative to the fixed rod 15, and the tension spring 19 is stretched. When the sliding baffle plate 13 moves to a certain height, the impact force of the feed is reduced and the upward movement speed is slowed down, the tension spring 19 rebounds, and the front end of the fan-shaped plate deflects upward, thereby colliding head-on with the falling feed, and the discharged agglomerated feed is slapped and crushed. In this process, the periodic discharging can give the mechanical mechanism enough reaction time, thereby greatly improving the probability of the fan-shaped plate rebounding and hitting the feed, and enhancing the impact and crushing effect;

[0038] When the feed lumps are hard and are not broken by tapping, they slide down to the V-shaped space of the triangular extrusion head 24 bracket under the shaking of the fan-shaped plate. When the sliding material blocking plate 13 moves up or the feed hits the front end of the fan-shaped plate, the triangular extrusion head 24 moves up and cooperates with the extrusion teeth 22 to crush the lumps. The V-shaped structure is convenient for the feed lumps to slide into the mixing barrel 1 after being crushed.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
