Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery equipment, and specifically to a high-performance dual-purpose branch and wood feed grinder. Background Art

[0002] In agricultural labor, the processing and pulverization of feed are crucial. It can pulverize various raw materials such as corn, soybeans, wheat bran, hay, straw, rice straw, etc. into particles or powders suitable for animal digestion and absorption, improve the taste and nutritional value of the feed, and promote animal growth and health. The key behind this technology is to improve feed utilization rate, reduce feed costs, and improve agricultural production efficiency, so as to meet the growing demand for livestock farming; during the agricultural production process, a lot of fallen branches, useless waste wood, trees and other woods will be generated. For the pulverization and crushing processing of wood branches, farms or agricultural enterprises may have a large amount of agricultural waste such as branches and leaves that need to be processed, which is also an essential link in agricultural labor activities. Usually, through pulverization and crushing treatment, these wastes can be converted into powders or small particles, which are convenient for treatment and utilization. Wood branches are also one of the common raw materials for making compost. After pulverization and crushing treatment, wood branches are more easily decomposed, which helps the preparation process of compost and improves the quality of compost. After the wood branches are pulverized, wood chips can be obtained. The wood chips can be used as raw materials for biomass energy, such as biomass fuel, wood chip pellets, etc., and can also be used for the production of paper, wood-based panels, etc.

[0003] Existing wood pulverizing equipment is usually single-functional and uses a roller-type stirring or cutting method for crushing; there are also some dual-functional pulverizing equipment, such as the dual-purpose plant material cutting and pulverizing machine of Chinese invention patent CN101786034A. Although it can pulverize feed and branches, etc., the feeding direction is directly into the rotating direction of the cutter head, and the cutting flying knife blade contacts the material, that is, the feeding is all from the same inlet, and after cutting, it directly enters the pulverizing chamber. Since the feeding direction is the same as the vertical direction of the cutter head, it causes some materials to enter the gap between the cutter heads and cannot be cut and crushed first, resulting in strong randomness of the pulverization degree, poor uniformity in the discharging process, easy blockage when using a sieve plate type for discharging, high demand for motor energy consumption, high tool wear rate, and low efficiency. Summary of the Invention

[0004] To solve the above-mentioned deficiencies and defects existing in the prior art, after improved design by the inventor, a new structural design is now provided, which can efficiently and smoothly process the cutting and chipping of wooden strips and branches, improve the uniformity of chipping and the cutting quality, and solve the problems of blockage, low efficiency, and poor quality caused by poor uniformity of chipping in the prior art. Specifically, the present invention is implemented as follows:

[0005] A high-performance dual-purpose branch wood feed crusher, comprising a frame, a crushing chamber installed on the frame, and a discharge bin located below the crushing chamber, and a crushing cutter head group installed in the crushing chamber. The crushing cutter head group includes:

[0006] A Fire Wheel double cutter head, installed at the inner end of the main shaft and close to the side where the branch wood feed inlet is located. The outer cutter head is a thickened cutter holder disc, with several teeth arranged on the edge, and 4-6 cutter holder plates are provided on the inner side surface of the cutter holder disc; the inner cutter head is an annular structure installed on the cutter holder plate, and several toothed rubbing blades are installed.

[0007] Several bottom cutters with inclined surfaces. Several irregular polygon-shaped openings are provided on the disc surface of the cutter holder disc. Each opening corresponds to a cutter holder plate, and one bottom cutter is installed on each cutter holder plate, so that the inclined cutting edge of the bottom cutter extends obliquely to the window of the opening of the cutter holder disc, and the cutting edge is in stable fit with the plane of the cutter holder disc.

[0008] Several crushing discs, with several cutter teeth arranged on the edge, are successively installed on the main shaft, and a secondary shaft is installed through them.

[0009] Several hammer pieces are rotatably suspended and installed on the secondary shaft.

[0010] An inertial wheel is installed on the main shaft, placed between the Fire Wheel double cutter head and the crushing disc, or installed between the outer side of the crushing disc and the bearing seat.

[0011] Further, the toothed rubbing blades are triangular or trapezoidal, with tooth patterns provided on the side edges, the number is 3-6 pieces, and the sizes are the same. They are evenly distributed on the inner cutter head and the height is higher than the edge height of the inner cutter head.

[0012] Further, nodular cast iron tooth plates are installed on the front and rear bin walls of the crushing chamber, and at least one row of convex teeth arranged horizontally is installed on the nodular cast iron tooth plates.

[0013] Further, the branch wood feed inlet is arranged at a corner of the side wall of the crushing chamber, in the form of an inclined downward inclined plane channel structure. Waist-shaped holes are provided on the bottom surface of the channel, and the fixed cutter is installed and fixed on the waist-shaped holes through bolts. The fixed cutter extends inward along the inclined plane of the channel, and the cutting edge of the fixed cutter just extends into the crushing chamber only. The cutting thickness of the wood branches can be controlled by adjusting the distance between the cutting edge of the fixed cutter and the cutting edge of the bottom cutter.

The isolation plate or the sieve plate is designed with a corresponding curvature and can be inserted into the crushing chamber along the slots. A sawdust discharge port and a discharge table are formed on the rear wall of the crushing chamber. The upper opening of the discharge table is an arc surface structure adapted to the curvature of the slots. The end of the discharge table is connected to the sawdust discharge port. A notch adapted to the arc surface structure is formed at a corner of the isolation plate. When the isolation plate is inserted in place, the notch is docked with the arc surface structure, so that the crushing chamber is communicated with the sawdust discharge port.

An insertion plate slot is provided at the tree branch and wood feed inlet for inserting the insertion plate.

[0020] Introduction to the working principle of the present invention: The core of this crusher is mainly a crushing disc group for crushing. It can also process and crush branches and wood with the cooperation of the double-knife disc of the wind-fire wheel, having a dual-purpose function. When processing branches and wood, lateral feeding is utilized, enabling the wood to first contact the outer knife disc of the double-knife disc of the wind-fire wheel. The bottom knife on the outer knife disc and the fixed knife at the entrance are used to quickly cut and slice the wood branches. The shredded materials after slicing or cutting enter the crushing chamber through the non-equilateral polygon-shaped openings. First, they come into contact with the inner knife disc of the double-knife disc of the wind-fire wheel, and after being further broken by the teeth on its edge, they are smoothly thrown horizontally into the crushing chamber in a lateral direction. For larger particles or longer branches, they are further broken and shredded by the tooth-rubbing blades on the outer knife disc to ensure that the materials entering the crushing chamber enter with a smaller size and volume. Subsequently, they come into contact, collide, rotate and cut, and agitate with the high-speed rotating crushing discs and hammer pieces, driving the material debris to swirl in the crushing chamber and contacting the convex teeth on the ductile iron tooth plates installed on the chamber wall, generating a shearing effect to further cut the materials. Along with the airflow in the crushing chamber, they are finally thrown out from the sawdust discharge port; The inertia wheel is at the other end of the main shaft, and it can generate rotational inertia during rotation, driving the cutting force of the entire main shaft and improving the cutting force of the outer knife disc. When cutting branches and wood, it is smooth, efficient, and has good cutting performance; During the crushing process, in addition to the cutting motion, the knife rest plate on the double-knife disc of the wind-fire wheel, which serves as the skeleton for installing the inner knife disc to provide support and fixation, can also be installed in a turning shape and serve as an impeller to generate a propelling airflow. Cooperating with the throwing and conveying plates between the crushing discs, it can form an overall airflow guidance in the crushing chamber to drive the materials to rotate, avoiding dead-angle materials and accumulation at the bottom of the bin wall, improving the crushing efficiency and the discharge rate; The lateral feeding and cutting for shredding feeding direction and the structural design of the double-knife disc of the wind-fire wheel ensure the pre-cutting of branches and wood first, ensuring that the size difference between the shredded materials is relatively stable and uniform when contacting the pre-crushing disc, thus improving the processing quality and crushing efficiency. When crushing branches and wood, there is no need to use a sieve plate, and the whole process is smooth, continuous, efficient, and stable. When feed crushing is required, replace the isolation plate with a sieve plate, close the movable baffle, and add the feed from the top entrance. The feed grains and rice bran will directly enter the crushing chamber from above and be crushed under the action of the crushing discs and hammer pieces until the particle size is smaller than the sieve holes and passes through the sieve holes into the discharge bin and is discharged from the discharge door.

[0021] Advantageous technical effects of the present invention compared with the prior art:

[0022] (1) The structure of the Fire Wheel double cutter disc uses multiple groups of bottom cutters on the outer cutter disc and cooperates with the fixed cutter at the feeding inlet of the branch wood to achieve special cutting of the branch wood, enabling the material to be first cut into sections or slices and then crushed into particles under the action of the teeth of the inner cutter disc and the toothed crushing blades. This can be regarded as a pretreatment, quickly completing slicing, sectioning, and then crushing according to a specific process. The staged treatment has strong pertinence and is the basis for the homogenization and stable and smooth crushing effect, ensuring the crushing quality of the wood.

[0023] (2) The bottom cutter and the fixed cutter are dedicated to the cutting of wood, with strong specificity, convenient for separate replacement and maintenance, and small in material consumption and low in maintenance cost; it reduces the processing intensity requirements for the crushing disc, can extend the service life of the crushing disc and the hammer pieces, and reduces the maintenance frequency and cost; in cooperation with the design of the inertial wheel, it can ensure the smoothness and stability of the wood branch cutting process.

[0024] (3) Through the design of the tool rest plate, the Fire Wheel double cutter disc structure can not only perform cutting and crushing but also provide a certain amount of air transportation, which is the key to promoting lateral feeding. The wood particles enter the crushing chamber laterally and contact the crushing disc more fully and evenly. In cooperation with the throwing conveying plate, the wood chips can move, collide, and be cut and crushed sufficiently in the crushing chamber, avoiding the problem of uneven crushing caused by the dead corners generated by the gaps between the crushing discs, and providing continuous air flow to push, providing air flow power for discharging, and realizing the characteristics of high efficiency, smoothness, and stability in the process of crushing wood.

[0025] (4) Through the design of the replaceable plug board, the installation of the isolation board or the sieve board can be realized, and the processing purpose can be selected according to needs. It has two feeding ports, distinguishing the feeding and discharging inlets of the wood branches and other feeds, realizing the function of multi-material processing and expanding its functional uses.
