Abstract

The utility model discloses a feed grinder which comprises a casing with a feeding port at the lateral portion. A discharging port is arranged on one side of the lower portion of the casing, a spindle is arranged in the middle of the casing, and one end of the spindle extends out of the casing and is provided with a transmission wheel which can be in transmission chaining connection with a power device. The spindle positioned in the casing is provided with a grinding mechanism, screening piece fixing plates are symmetrically arranged on the inner surfaces of the two lateral walls of the casing, two clamping arms extending inwards are arranged on the lateral walls of the casing, and a feeding channel is formed between the two clamping arms. Arc-shaped screening pieces are inserted between the clamping arms and the screening piece fixing plates, inserting grooves enabling the screening pieces to be inserted in are arranged on the casing, and a grinding cavity is defined by the clamping arms, the screening pieces and the screening piece fixing plates jointly. The ground feed can leave the grinding cavity at any time through the screening pieces, so that repeated grinding of the feed is avoided, and grinding efficiency is improved. The screening pieces are inserted into the casing through the inserting grooves arranged on the lateral walls of the casing, and accordingly, the screening pieces can be installed and replaced simply and conveniently.

Description

A kind of feed grinder

Technical field

The utility model belongs to the pulverizer technical field, and it is high and be convenient for changing the feed grinder of sieve specifically to relate to a kind of crush efficiency.

Background technology

At present, the sieve of the employed tangential feeding hammer type feedstuff crasher of people is installed on the lower house by bolt, the existing major defect of the mounting structure of this sieve is: 1, because sieve only is installed in lower house, feed after the pulverizing can only be by the sieve discharging of bottom, be positioned at grinding fodder and again being pulverized by hammer leaf of upper shell, make to have serious repetition crushing phenomenon in the process, cause crush efficiency low; 2, owing to adopted the bolted sieve, when needs are changed sieve, need to turn on fastening bolt, its complicated operation.

The utility model content

The technical problems to be solved in the utility model provides a kind of crush efficiency height and is convenient for changing the feed grinder of sieve.

For addressing the above problem, the feed grinder that provides comprises that sidepiece is provided with the housing of charging aperture, bottom one side of housing is provided with discharging opening, main shaft is equipped with at the middle part of housing, one end of main shaft stretch out housing outer and be equipped with can with the drive of power set transmission link, the main shaft that is positioned at housing is equipped with disintegrating mechanism, its design feature is: the two side inner surface of described housing is equipped with the sieve fixed head, two jig arm also are housed on the sidewall of housing, it is feeding-passage between two jig arm, be fitted with the sieve of arc between jig arm and the sieve fixed head, housing is provided with the slot that inserts for sieve.

After adopting said structure, the feed link of needs pulverizing is crossed charging aperture to be entered in the housing, under the driving of power set, finish the crushed work of feed by disintegrating mechanism, feed behind the flour can leave crushing chamber at any time by the sieve that is centered around the disintegrating mechanism border, avoid the pulverizing that repeats of feed, improved crush efficiency; And can sieve be inserted in the housing by the slot that arranges on the housing sidewall, by the cooperation of sieve fixed head and jig arm sieve is fixed, make installation and change sieve to become very simple and convenience.

Described disintegrating mechanism comprises at least two hammer frame plates that are set in parallel on the main shaft, and the hammer slice axis parallel with main shaft is installed on the hammer frame plate, is rotatably connected to a plurality of hammer leaves on the hammer slice axis.

Described housing comprises the upper shell that is fitted together and lower house, the sieve fixed head comprises the upper sieve fixed head that is packed in the upper shell and the lower sieve fixed head that is packed on the lower house inwall, one end of upper sieve fixed head and lower sieve fixed head is affixed, and the other end of upper sieve fixed head and lower sieve fixed head cooperates with jig arm respectively fixes sieve.

The other end of described main shaft stretches out outside the housing and is connected with the rotating shaft transmission of blower fan, and the import of described blower fan is communicated with by carrier pipe with described discharging opening.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of analysing and observe along the A-A line among Fig. 1.

The specific embodiment

Feed grinder as shown in drawings, comprise housing 1, housing 1 is supported by bearing 14, one sidepiece of housing 1 is provided with the charging pallet, and the charging pallet is provided with charging aperture 2, and bottom one side of housing 1 is provided with discharging opening 10, main shaft 4 is equipped with at the middle part of housing 1, one end of main shaft 4 stretch out housing 1 outer and be equipped with can with the drive 5 of power set transmission link, the other end of main shaft 4 stretches out that housing 1 is outer to be connected with the rotating shaft transmission of blower fan 11, the import of blower fan 11 is communicated with by carrier pipe 16 with discharging opening 10.Be positioned on the main shaft 4 of housing 1 disintegrating mechanism is housed, this disintegrating mechanism can comprise at least two hammer frame plates 12 that are set in parallel on the main shaft 4, hammer frame plate 12 and main shaft 4 vertical settings, the hammer slice axis 13 parallel with main shaft 4 is installed on the hammer frame plate 12, be rotatably connected to a plurality of hammer leaves 15 on the hammer slice axis 13, hammer leaf 15 is prior art with the mounting structure of hammer slice axis 13, does not repeat them here.The two side inner surface symmetry of housing 1 is equipped with around the sieve fixed head 3 of the arc of disintegrating mechanism periphery, stretching in also in the position of the corresponding charging aperture 2 of the sidewall of housing 1 has two jig arm 6 that cooperate with sieve fixed head 3, be feeding-passage 17 between two jig arm 6, be fitted with the sieve 7 of arc between jig arm 6 and the sieve fixed head 3, housing 1 is provided with the slot 9 that inserts for sieve 7, and jig arm 6, sieve 7 and sieve fixed head 3 surround crushing chamber 8 jointly.Above-mentioned housing 1 can comprise the upper shell 1-1 that is fitted together and lower house 1-2, sieve fixed head 3 comprises the upper sieve fixed head 3-1 that is packed in the upper shell 1-1 and the lower sieve fixed head 3-2 that is packed on the lower house 1-2 inwall, the end of upper sieve fixed head 3-1 and lower sieve fixed head 3-2 is solidly installed by geometrical clamp, and the other end of upper sieve fixed head 3-1 and lower sieve fixed head 3-2 cooperates respectively sieve 7 fixing with jig arm 6.
