Abstract

An agricultural grinder is mainly characterized in that: the machine shell is arranged on the machine seat, a main shaft with belt transmission wheel is assembled in the center of the machine shell. The main shaft inside the machine shell is provided with a fan which has a casing. Moreover, the main shaft still has supporting racks in symmetry, and four parallel revolving knife-type axial rods with hammer slices are positioned between the supporting racks. The side ends of the supporting rack have an upper revolving knife and a lower revolving knife which are fixed on the side wall near the main shaft and which match with a positioning knife. The two sides, the middle part and the lower part on top of the side wall of the machine shell are respectively provided with a material inlet straw exit, a straw inlet and a material exit. The utility model can be used to fast crush dry and wet corn-sticks, corn straw and dry and wet green grass.

Description

Agricultural mill

Affiliated technical field

The utility model belongs to agricultural mill, particularly relates to the device that various crops such as corn ear, corn stalk wheat straw are pulverized.

Background technology

At present, the agricultural mill that China generally uses in the rural area, generally be cracker and fan split setting, promptly not in uniform machinery, air-introduced machine is generally positioned at pulverizes the casing outside, and this device volume is big, power consumption big, pulverizing speed is slow, cost is higher, because imbalance during the rotation of the fan of air-introduced machine, therefore, the loosening various mechanical breakdowns that cause of each parts easily take place in long-time the use.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of simple in structure, reasonable in design, easy for installation, the agricultural straw cracker of good crushing effect.

In order to achieve the above object, the technical solution adopted in the utility model is: casing is installed on the support, a side has the spindle mounted of belt pulley in the casing center in the casing, the casing inner main axis is equipped with the fan of band guard shield, also be equipped with the bracing frame of symmetry on the main shaft, install four between the bracing frame and parallelly revolve the axostylus axostyle that cutter-type has hammer leaf, on the bracing frame side has, the backspin rotating knife is fixed in close main shaft place and cooperates stationary knife on the sidewall, both sides, chassis sidewall top, the middle part, the bottom is respectively equipped with feed entrance straw discharging opening, straw feeding mouth and discharging opening.

The utility model has the advantages that:

Simple in structure, reasonable in design, power consumption is little, pulverizing speed is fast, can the crushing maize rod, corn stalk and variously do wet this device long service life of wheat straw crop, low this device of fault rate can by the user need adjust in this machine hammer leaf or hammer leaf or sieve plate carry out the different crops of grinding particle size.

Embodiment:

In conjunction with the accompanying drawings the utility model embodiment is described in further detail.

By Fig. 1-Figure 10 as can be known the utility model be that casing 1 is installed on the support 2, the main shaft 4 that casing 1 an interior side has belt pulley 3 is assemblied in casing 1 center, casing 1 inner main axis 4 is equipped with the fan 6 of band guard shield 5, also be equipped with the bracing frame 12 of symmetry on the main shaft 4, install four between the bracing frame 12 and parallelly revolve the axostylus axostyle 8 that cutter-type has hammer leaf 7, on bracing frame 12 sides have, backspin rotating knife 9 is fixed in close main shaft 3 places and cooperates stationary knife 10 on the sidewall, casing 1 side wall upper part both sides, the middle part, the bottom is respectively equipped with feed entrance 11 straw discharging openings 13, straw feeding mouth 14 and discharging opening 15.

Described casing I inner top has bounce-back sloping baffle 16.

Described casing 1 inwall is provided with double wedge 17.

Closed arc 18 is equipped with in the bottom in the described casing 1.

Sieve plate 19 also is equipped with in the bottom in the described casing 1.

Described guard shield 5 coincide mutually and is installed on fan 6 support arms.

The utility model is work like this:

Connect the power supply rear motor and drive main axis rotation by the belt drives belt pulley, make and be installed on also rotation simultaneously of bracing frame, rotate synchronously by the four parallel axostylus axostyles and the main shaft that are fixed on the bracing frame, make the mutual rotary-cut of the hammer leaf that is assemblied on the axostylus axostyle, the moving knife and the bracing frame that are fixed on the supporting side walls are synchronous, rotate and the stationary knife rotary-cut crops of matching.Described bounce-back baffle plate is that the bounce-back baffle plate is installed when crushing maize straw or wheat straw, simultaneously closure plate is installed also, and pulverized corn stalk or wheat straw are flown to the bounce-back baffle plate at a high speed, are launched.Because the fan high speed rotating, with broken to the straw discharging opening, when the crushing maize rod baffle plate that will rebound takes off.Closure plate changes the outfit and is sieve plate simultaneously, makes by the crushing maize rod and exports along discharging opening.Described guard shield is that corn ear damages fan propeller, and therefore guard shield is installed.
