Description

Large-scale pulverizer for livestock breeding

Technical Field

The invention relates to the technical field of grain feed grinding, in particular to a large-scale grinder for livestock breeding.

Background

The large-scale pulverizer for livestock cultivation is used for pulverizing various feed raw materials (such as straw, corn, wheat, bean pulp and the like) into small blocks or fine particles so as to meet the feed requirements of livestock. Through crushing, the digestibility and the nutritive value of the feed can be improved, and the production efficiency of livestock is further improved.

The utility model discloses a fodder grinder for animal husbandry breed like CN114713327A, though can realize setting through fodder grinder, make it have functions such as breakage, dust collection, dual screening, grind for the fodder can separate and refine, make the fodder be applicable to different animals and eat, not only avoided influencing the condition of unloading to take place effectively, also avoided grinding not good condition to take place simultaneously, but there is the defect that can not handle big granule stone and the material is static to pile up easily on the screen cloth and cause the unloading to block up, and the crushing roller can not grind the material comprehensively.

The summary is as follows:

1. The materials are statically piled on the screen, the materials to be ground are poured into the feed bin in advance, and then the materials are finely screened through the screen, so that the granularity of the materials entering the grinding stage is ensured to be uniform, the requirements of the subsequent process are met, however, when the materials are poured onto the screen in a large amount, the materials are statically piled together due to the weight of the materials and the friction force between the materials, and an aggregate which is difficult to disperse is formed. In this case, if vibration is only generated by the driving component of the machine body, the effect is often unsatisfactory. Because excessive material accumulation weakens the transmission effect of vibration, the material on the screen is difficult to be effectively dispersed and screened, and when the material on the screen is accumulated to a certain degree, the vibration of the machine body may not even penetrate the material layer, resulting in a sharp drop in screening efficiency. This not only increases the screening time and increases the energy consumption, but also may affect the quality and efficiency of the subsequent grinding operation because the screening is not complete.

2. The utilization of the crushing rolls is poor, and the crushing rolls are usually mounted in parallel and tightly by two elongated rolls, which crush the material to the desired particle size by pressing and friction against each other, however, in practice the distribution of the material over the crushing rolls is not uniform. The material tends to accumulate more in the middle region of the crushing roller due to the gravity of the material itself and the manner of feeding. Thus, the rollers in the middle region need to bear larger crushing pressure, so that the wear speed is increased, and the crushing efficiency is reduced due to material accumulation. In contrast, the two end regions of the crushing roller are not fully utilized because of less material distribution, and even in some cases, when the material is completely crushed, the roller can continue to idle without the material, which not only wastes energy, but also further reduces the utilization rate of the crushing roller.

Aiming at the problems, innovative design is urgently needed on the basis of the prior large-scale pulverizer for livestock cultivation.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 10, the invention provides a large-scale crusher for livestock cultivation, which comprises a frame 1, a feeding barrel 2 rotatably arranged in the frame 1 through a driving component for feeding grains, an elastic screening component arranged in the feeding barrel 2 for screening large granular stones and preventing static accumulation of grains, a spreading grinding structure and a blanking component arranged at the bottom of the feeding barrel 2 for filling blank spreading, wherein a spiral blanking opening 201 for blanking grains and forming a spiral shape is formed in the inner wall of the bottom of the feeding barrel 2, and a notch of the spiral blanking opening 201 is attached to a feeding opening of the spreading grinding structure.

Specifically, firstly, the materials to be ground are poured into the feed hopper 2, the materials are then placed on the elastic screening assembly, when the pouring amount of the materials is large, the accumulated weight of the materials can apply pressure to the central area of the elastic screening assembly, the pressure drives the elastic screening assembly to shrink, the chain reaction leads the central part of the elastic screening assembly to integrally extend downwards, meshes in the elastic screening assembly are expanded, wherein the meshes are not expanded so much, the meshes are expanded so as to only allow the materials to pass, thereby being beneficial to realizing more efficient screening and discharging of the stacked materials through the expanded meshes and vibration generated when the pulverizer is operated, the screened materials are finally deposited at the bottom of the feed hopper 2, and then, the driving assembly drives the feed hopper 2 to rotate at a uniform speed in the frame 1 through the action of a belt.

At this time, since the spiral discharging opening 201 is a spiral opening, the overlapping area of the spiral discharging opening 201 and the spreading opening 9 is different at each rotation angle, so that a special material guiding mode between the spiral discharging opening 201 and the spreading opening 9 can be utilized, materials can be spread along the spreading opening 9 from inside to outside and from outside to inside, but the materials are not dropped at a fixed position of the grinding gap, a large amount of materials are prevented from being accumulated at a certain position, grinding and idling are performed in other areas, the utilization rate is poor, and the materials are efficiently collected and discharged through the discharging assembly after the grinding is completed.

The elastic screening assembly comprises a screen 5 for screening large granular stones and preventing static accumulation of grains, an elastic rod 6 which is arranged at the center of the bottom of the screen 5 in a lamination manner through a jacking block 601 and is used for elastic jacking and is pressed down by accumulation of grains, and a main shaft rod 14 which is arranged at the center of the feed barrel 2 in a penetration manner and is elastically telescopic through a spring.

The border fixedly connected with screen cloth 5, and the border of screen cloth is the slip setting with the inner wall of feedwell 2, and the outer wall fixedly connected with of elastic rod 6 is circular array distribution's connecting piece 10, and rotates on the connecting piece 10 and be provided with the flexible adjusting lever 7 that prevents screen cloth 5 distortion, and the other end of flexible adjusting lever 7 is articulated mutually with the bottom at screen cloth border.

Specifically, the accumulated weight of the material applies pressure to the central area of the screen 5, which in turn drives the elastic rod 6 at the bottom of the screen 5 and its top block 601 to retract inside the spindle shaft 14, compressing the springs in the process. This chain reaction results in the screen 5 extending downward as a whole, the mesh is thus expanded, the screened material eventually settles at the bottom of the feedwell 2, and as the material on the screen 5 gradually decreases, the weight of the screen 5 correspondingly decreases, and at this time the resilience of the spring begins to act, pushing the resilient rod 6 and its top block 601 to extend upward, and further driving the screen 5 to deform upward, forming an inverted arc. This deformation not only makes the mesh of screen cloth 5 become finer, still through the resilience of elastic rod 6 and the curved structural feature of screen cloth 5, promotes great stone granule to the screen cloth 5 both sides removal to finally pile up at the edge of feedwell 2, the in-process of deformation is through the design of flexible adjusting lever 7, thereby avoids screen cloth 5 to take place distortion at the in-process of deformation.

The lapping material grinding structure comprises lapping material openings 9 and grinding rollers 8, wherein the lapping material openings 9 are distributed in a circular array and are used for filling blank-type lapping materials, and grinding joints between the grinding rollers 8 and the lapping material openings 9 are concentrically distributed on a horizontal plane so as to ensure that materials uniformly fall into the grinding joints and are efficiently ground.

The bottom of the main shaft lever 14 is rotatably provided with a driving wheel 13, the bottom of the driving wheel 13 is fixedly connected with a curved fluted disc 11, teeth of the curved fluted disc 11 are meshed with a driven gear 12, and the driven gear 12 is connected with a driving roller of the grinding roller 8.

Specifically, the lower end of the spreading hole 9 is parallel to and corresponds to the grinding gap of the grinding roller 8, and as the spiral blanking hole 201 is a spiral opening, the overlapping area of the spiral blanking hole 201 and the spreading hole 9 is different in each rotation angle, the effect is achieved that the material can be spread from inside to outside along the spreading hole 9 by utilizing a special material guiding mode between the spiral blanking hole 201 and the spreading hole 9 instead of falling down at a fixed position of the grinding gap, so that the material is prevented from being accumulated at a certain position in a large amount, and other areas are ground and idle, and the utilization rate is poor.

The blanking assembly comprises a conical feed guiding slope 4 for feeding ground feed and a blanking barrel 3 sleeved outside the feed guiding slope 4 and used for gathering ground materials, and the inner wall at the bottom of the feed guiding slope 4 and a shaft lever at the bottom of the driving wheel 13 are arranged in a rotary sliding mode.

Specifically, the guide slope 4 is a conical surface, the ground material can fall on the conical surface of the guide slope 4 and can fall along the conical surface of the guide slope 4 along with the running vibration of equipment, and finally enter the blanking barrel 3 with an inner conical surface, and after the lower end of the blanking barrel 3 is folded, the ground material is gathered and falls down from the center of the blanking barrel 3, so that the efficient collection and discharge of the material are ensured.

One end of the grinding roller 8 penetrates through the outer wall of the blanking cylinder 3, and the end part of the grinding roller, which is exposed on the outer wall of the blanking cylinder 3, is rotatably provided with a transmission gear 801 which is meshed with each other.

The drive assembly comprises a pulley which drives the feedwell 2 in rotation by means of a belt and a drive wheel 13.

When the large-scale crusher for livestock cultivation is used, firstly, the materials to be ground are poured into a feed barrel 2 at one time, the screen 5 is in an inverted arc shape with the cone tip upwards as shown in fig. 2 in the initial condition, when a large amount of dense materials directly fall on the screen 5, the dense materials can be regarded as a whole to generate certain impact force to the screen 5 at the moment of contacting the screen 5 so as to cause the deformation of the screen 5, so that the cone tip of the screen 5 instantaneously falls down and drives an elastic rod 6 at the bottom of the screen 5 and a top block 601 thereof to shrink towards the inside of a main shaft rod 14, and the spring is compressed in the process. This chain reaction causes the screen 5 to extend downwards as a whole, expanding the mesh openings, wherein the mesh openings are not so large that only material is allowed to pass through, thereby facilitating more efficient screening and blanking of the deposited material through the expanded mesh openings and the vibrations generated when the pulverizer itself is operated, and the screened material is finally deposited at the bottom of the feedwell 2, and then the drive assembly drives the feedwell 2 to rotate at a constant speed in the frame 1 by the action of the belt.

At this time, since the spiral discharging opening 201 is a spiral opening, the overlapping area of the spiral discharging opening 201 and the spreading opening 9 is different at each rotation angle, so that a special material guiding mode between the spiral discharging opening 201 and the spreading opening 9 can be utilized, materials can fall down along the spreading opening 9 from inside to outside and from outside to inside instead of spreading materials from outside to inside at a fixed position of a grinding gap, a large amount of materials are prevented from accumulating at a certain position, and other areas are ground and idle, so that poor utilization rate is caused, the ground materials can fall on the conical surface of the material guiding slope 4 and fall down along the conical surface of the material guiding slope 4 along with the running vibration of equipment, finally enter into the discharging barrel 3 with an inner conical surface, are gathered and fall down from the center of the discharging barrel 3 after being gathered through the lower end of the discharging barrel 3, and high-efficiency collection and discharge of the materials are ensured. Along with the gradual passing of the material on the screen 5 through the meshes, the downward pressure applied to the screen 5 is gradually reduced, and the resilience force of the spring starts to act at the moment to push the elastic rod 6 and the top block 601 thereof to extend upwards, so as to drive the screen 5 to deform upwards to form an inverted arc shape. This deformation not only makes the mesh of the screen 5 finer, but also promotes the movement of larger stone particles to both sides of the screen 5 and finally piles up on the edge of the feedwell 2 by the resilience of the resilient rod 6 and the structural characteristics of the arc shape of the screen 5. At this time, the vibration generated by the feed barrel 2 under the action of the driving component further helps the stones to be effectively screened out of the feed barrel 2, so that the fine materials meeting the grinding requirements are always reserved under the screen 5. Not only improves the overall working efficiency of the pulverizer, but also ensures the quality and uniformity of the ground materials.

Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
