A kind of organic fertilizer fermentation heap turning over device
Technical field
The utility model relates to the fermentation unit in a kind of organic fertilizer production, is a kind of organic fertilizer fermentation heap turning over device specifically.
Background technology
In the production process of fertilizer, need regularly the fertilizer raw material of fermentation to be carried out to turning, reduce fermentation materials temperature with this, improve the survival rate of beneficial microorganism bacterium, can improve the oxygen in fertilizer raw material by turning simultaneously, make fermentation more abundant, can effectively improve organic nutrient content.Chinese patent 2013201876183 discloses a kind of " fertilizer fermenting raw materials heap turning over device ", adopts motor, chain-drive turning wheel to walk while turning over materials, reaches the object of turning.Its turning wheel is with the turnover panel of radial connection, and along with the rotation of turning wheel, turnover panel is provoked material to stir opposite side.This pile assembly replaces artificial turning operation, has the advantages that labour intensity is low, efficiency is high.But meanwhile, its turning wheel structure design is unreasonable, turnover panel is stressed large, easily fractures or comes off from turning wheel, and material turning is not thorough.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, long service life, material turning organic fertilizer fermentation heap turning over device thoroughly.
For achieving the above object, the utility model is by the following technical solutions:
A kind of organic fertilizer fermentation heap turning over device described in the utility model comprises that both sides are provided with the hull of road wheel and are fixedly mounted on the drive-motor on hull, the heap turning over device being in transmission connection with drive-motor, described heap turning over device comprises the rotating shaft being in transmission connection with drive-motor and is fixedly connected on the double helix plate group in rotating shaft, described double helix plate group comprises two spiral laths that arrange centered by rotating shaft, the hand of spiral of described two spiral laths is contrary, one end of two spiral laths is fixedly attached in rotating shaft by drive end connecting rod, the other end of two spiral laths is connected on driven shaft by follower link, described driven shaft is connected on support by bearing, described support is fixedly connected on the lower end of hull.
On described hull, be installed with the transmission gear box of longitudinal setting, the power input shaft of described transmission gear box connects drive-motor, the power output shaft connection rotating shaft of transmission gear box; Described spiral lath is provided with through hole; Between two spiral laths in same double helix plate group, be provided with support bar.
Adopt after technique scheme, this heap turning over device adopts the spiral lath turning over materials that two hands of spiral are contrary, spiral lath sound construction, reasonable in design, long service life, material turning is thorough, be conducive to reduce the maintaining cost of equipment, improve the fermented quality of organic fertilizer product.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the cross section view of double helix plate group.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
As shown in Figure 1, a kind of organic fertilizer fermentation heap turning over device described in the utility model comprises the heap turning over device that both sides are provided with the hull 1 of road wheel 15,16 and are fixedly mounted on drive-motor 2 on hull 1, are in transmission connection with drive-motor 2.When use, road wheel is arranged in the track on fermentation vat, utilizes manpower or Mechanical Driven power to drive hull 1 to walk, and heap turning over device work is by the material turning in fermentation vat.
Described heap turning over device comprises the rotating shaft 3 being in transmission connection with drive-motor 2 and is fixedly connected on the double helix plate group in rotating shaft 3.As shown in Figure 2, described double helix plate group comprises the two spiral laths 4,5 that arrange centered by rotating shaft 3, the hand of spiral of described two spiral laths 4,5 is contrary, one end of two spiral laths 4,5 is fixedly attached in rotating shaft 3 by drive end connecting rod 6, the other end of two spiral laths 4,5 is connected on driven shaft 8 by follower link 7, described driven shaft 8 is connected on support 9 by bearing, and described support 9 is fixedly connected on the lower end of hull 1.Rotating shaft 3 and driven shaft 8 can be two axles of coaxial setting as shown in Figure 1, can be also the same axises that runs through two ends.In a heap turning over device, can only have as shown in Figure 1 one group of double helix plate group, many groups double helix plate group of different diameter, different azimuth also can be set.
On described hull 1, be installed with the transmission gear box 10 of longitudinal setting, the power input shaft of described transmission gear box 10 connects drive-motor 2, the power output shaft connection rotating shaft 3 of transmission gear box 10, the inside of transmission gear box 10 can adopt chain gear also can adopt geartransmission; Described spiral lath 4,5 is provided with through hole 13; Between two spiral laths 4,5 in same double helix plate group, be provided with support bar 14.Through hole 13 also can reduce the resistance of motion of spiral lath, also can play the effect of dispersed material simultaneously, improves turning oxygenation efficiency; Support bar 14 can improve the rigidity of spiral lath, avoids torsional deformation.
