Description

A extrusion mechanism and forage grinder for forage grinder

Technical Field

The utility model relates to a pulverizer, in particular to a forage pulverizer.

Background

The forage grass mainly refers to herbaceous plants which can be used by livestock and poultry, and generally comprises two types of herbaceous plants which naturally grow on grasslands, wherein one type of herbaceous plants is taken directly by livestock or harvested manually and is used as food materials of livestock, namely pasture, and the other type of herbaceous plants which are domesticated and form feed after artificial cultivation, namely feed crops. Among them, the use of grass stalks is most common. The straw rod is characterized in that the interior is hollow, the cavity is large, and more space is occupied when crushing.

Therefore, the existing pulverizer presses and crushes the grass rod before pulverizing. For example, the patent publication No. CN218353354U, an animal feed breaker, the utility model extrudes the forage through a plurality of pairs of feeding rollers, so that the volume of the forage is reduced, and the forage does not occupy more space. However, in this structure, the feed roller is provided with a plurality of pairs. When in use, the forage extruded by the pair of feeding rollers is small in volume and flat, and the forage is lighter in weight. The feeding roller is easy to wind and adhere to the surface of the feeding roller, and the feeding roller is difficult to move downwards continuously when entering the feeding roller below, so that the blanking speed is reduced, and the crushing efficiency is affected.

Aiming at the problems that the forage is inconvenient to discharge and is easy to wind on the surface of a feed roller, the extrusion mechanism for the forage pulverizer and the forage pulverizer are provided.

Description of the embodiments

In order to better understand the technical solutions in the present application, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

The embodiment of the application provides an extrusion mechanism for a forage pulverizer and the forage pulverizer.

Example 1, as shown in fig. 1-4.

A forage extrusion mechanism comprises two groups of feeding rollers 11, wherein a plurality of feeding rollers 11 are arranged in each group, are vertically distributed, and are preferably 4 in number. The forage extrusion mechanism 1 further comprises a conveying belt 12, a limiting convex edge 13 and a conveying protrusion 14.

Each group of feeding rollers 11 is coated on the outer side of the conveying belt 12, limiting ribs 13 are arranged on two sides of the conveying belt 12, and a plurality of conveying protrusions 14 are arranged on the outer side surface of any conveying belt 12.

Wherein the two conveying belts 12 move relatively so as to flatten forage, and the conveying protrusions 14 drive the forage to move in the process of flattening the forage.

The feeding roller 11 drives the conveying belts 12 to move, and a small gap is reserved between the two conveying belts 12, so that forage is downwards moved through the gap, and is continuously extruded by the two conveying belts 12 while moving. Thereby flattening the forage and reducing the volume thereof.

The conveying belt 12 is coated on the outer side of the same group of feeding rollers 11, so that the flattened forage is prevented from adhering and winding on the surfaces of the feeding rollers 11. The flattened forage directly falls into the lower part for crushing. The spacing ribs 13 prevent forage from falling out from both sides of the conveyor belt 12 during extrusion, thereby being wound on the surface of the feed roller 11. The conveying protrusions 14 avoid that forage is accumulated at the inlets of the two conveying belts 12, and easily overflows the width range of the conveying belts 12, and then the forage is wound on the surfaces of the feeding rollers 11.

Wherein the conveying protrusions 14 only drive the forage to move and only partially contact with the forage. The conveyor belt 12 is in contact with the forage material as a whole, and extrudes the forage material to reduce its volume. When the conveyor belt 12 is selected, a material having a high compressive strength is preferable. Reducing the deformation of the forage material when the forage material is extruded as much as possible. Since the forage material itself is not strong, the pressure reaction force fed back to the conveyor belt 12 is also small. It is ensured that the conveyor belt 12 collapses the straw of the forage material.

The conveying protrusions 14 are in the shape of ribs. The conveying protrusions 14 in the shape of ribs press forage material through edges of the edges, so that the forage material is driven to move, and compared with other forms such as circular arcs and the like, the partial pressure is high, so that the conveying capability of the conveying protrusions 14 is higher.

The edges of the outer sides of the conveying bulges 14 opposite to the conveying direction are rounded. The rear edge is set to be in rounded transition, and the contact pressure of the conveying protrusion 14 and forage grass on the contact surface is gradually reduced, so that the conveying protrusion 14 and the forage grass can be prevented from being bonded to a certain extent.

The conveying protrusions 14 are hemispherical. The effect on forage extrusion is reduced as much as possible while the forage is driven to move. Avoiding that it occupies a large space and thus affects the extrusion of forage material by the conveyor belt 12.
