Summary of the invention

The object of the present invention is to provide a kind of flour mill, effectively can solve existing flour mill easily becomes block problem from the powder that discharging opening is discharged.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of flour mill, comprise driving motor, the main shaft driven by driving motor, there is the housing of crushing chamber, the discharging opening being arranged on the grinding mechanism in crushing chamber and being arranged on below housing, described driving motor is fixed on housing, also comprise the broken caking device being arranged on discharging opening, the middle part of described main shaft drives grinding mechanism to rotate, also driven shaft is provided with in the crushing chamber of described housing, the upper end of described driven shaft and the lower end of main shaft are by gear pair transmission, the lower end of described driven shaft passes housing and drives broken caking plant running.

Preferably, some pieces of vertical space bars are provided with in described discharging opening, described broken caking device comprises the first toggle, the second toggle and loose powder plate, space bar described in every block is all rotatably connected to loose powder plate, all space bars are divided into odd bits space bar and even bit space bar, odd bits space bar and even bit space bar are arranged alternately, the loose powder plate be connected with described odd bits space bar is driven by the first toggle and swings, and the loose powder plate be connected with described even bit space bar is driven by the second toggle and swings; By the swing of odd bits and even bit space bar, change the width of discharging opening, the powder for the one-tenth block extruded from discharging opening carries out side extruding makes it scatter.

Preferably, described driven shaft lower end is connected with the second toggle with the first toggle by gear pair, the first toggle and the second toggle synchronous axial system; Can realize the first toggle and the second toggle synchronous axial system accurately by gear pair transmission, and synchronous axial system can make the better collaborative work of loose powder plate of radix position and even bit.

Preferably, with the loose powder plate that described odd bits space bar connects and contrary with the loose powder plate swaying direction that described even bit space bar is connected; The powder of block can better be squeezed into from the side, ensure that agglomerating powders is squeezed loose.

Preferably, described loose powder plate cross section is one or more in waveform, arc or polygon; The loose powder plate shape of better squeezing loose effect can be reached.

Compared with prior art, advantage of the present invention is: this apparatus structure is simple, directly can transform existing equipment, carry out power transmission by installing driven shaft on original equipment additional, give broken caking device by the power transmission of main shaft, broken caking device is arranged on discharge outlet, broken by making the agglomerated particle transferred out from discharging opening squeeze, ensure normally carrying out of subsequent step, improvement cost is low, is easy to realize.

Fig. 1 is the structural representation of a kind of flour mill of the present invention;

Fig. 2 is the structural representation of broken caking device in a kind of flour mill of the present invention;

Structural representation when Fig. 3 is broken caking device work in a kind of flour mill of the present invention.

Detailed description of the invention

Consult the embodiment that Fig. 1 is a kind of flour mill of the present invention, a kind of flour mill, comprise driving motor 7, the main shaft 8 driven by driving motor 7, there is the housing 10 of crushing chamber 9, the discharging opening 1 being arranged on the grinding mechanism 11 in crushing chamber 9 and being arranged on below housing 10, described driving motor is fixing on the housing 10, also comprise the broken caking device 12 being arranged on discharging opening 1, the middle part of described main shaft 8 drives grinding mechanism 11 to rotate, driven shaft 13 is also provided with in the crushing chamber 9 of described housing 10, the upper end of described driven shaft 13 and the lower end of main shaft 8 are by gear pair 14 transmission, the lower end of described driven shaft 13 passes housing 10 and drives broken caking device 12 to run.

As Fig. 2, shown in Fig. 3, some pieces of vertical space bars 3 are provided with in described discharging opening 1, described broken caking device 12 comprises the first toggle 5, second toggle 6 and loose powder plate 4, described loose powder plate 4 cross section is waveform, one or more in arc or polygon, space bar 3 described in every block is all rotatably connected to loose powder plate 4, all space bars 3 are divided into odd bits space bar 3 and even bit space bar 3, odd bits space bar 3 and even bit space bar 3 are arranged alternately, the loose powder plate 4 be connected with described odd bits space bar 3 is driven by the first toggle 5 and swings, the loose powder plate 4 be connected with described even bit space bar 3 is driven by the second toggle 6 and swings.
