Cereal bagging device
Technical field
The present invention relates to field of mechanical technique, is specifically a kind of cereal bagging device.
Background technology
Annual summer Qiu Liangjishi peasant household and Liang Chu unit concentrate the time period of grain storage, therefore, need to carry out pack process to grain, so that the later stage better stores grain in silo.In prior art, the staff of most of silo carries out packing process to grain by artificial mode, and efficiency is low on the one hand, needs several staff's co-operating on the other hand, and therefore this traditional grain pack is wasted time and energy.
Therefore, there is mechanical bagging apparatus on the market, to enhance productivity.As " grain collects bag packer automatically " patent of invention that the patent No. disclosed on State Intellectual Property Office website is " ZL201210230214.9 ", it comprises leaks grain cleaning plant, auger, group grain device, elevator, wind power knot screen, grain intake mechanism, vibrating grizzly and magnetic impurity removing device, silo, quantitatively pack transport bag system, automatic bag sealing system, power and driving system etc., all devices are all fixed in frame, and collaborative work completes the collection of grain.It adopts auger that grain is delivered to elevator lower end, and grain is delivered to top by elevator again, and grain falls to sack from top.But this device structure is complicated, fuselage is huge, floor area is also large, be only applicable to the large granary of large space, and for those small-sized silos, this equipment is obviously inapplicable.
In addition, State Intellectual Property Office website also discloses " movable pneumatic grain bagging machine " utility model patent that the patent No. is " ZL02208631.5 ", it is by support, air operated mechanism and electrical control cubicles are formed by formant part, support is provided with wheel bottom a horizontal deckle board and top is provided with the car formula stand of support, air operated mechanism includes suction tank, grain output device, blower fan and high-order silo and the assembly of multistage connection pipe form semi-closed system, suction tank is that the air intake of the aspiration channel and outer company being connected to the connection of drawing on blower fan that height splits on the upside of a can body inhales grain flexible pipe, high-order silo shape roughly the same suction tank and be equiped with the movable grain-discharging short tube of band gate at its funnel mouth of pipe place.It first air intake is inhaled grain flexible pipe tube head insert bulk grain heap in, under the effect of blower fan, grain is inhaled into suction tank, then is allocated by grain output device, and then grain send grain transfering tube to enter high-order silo through wind, then fall into from movable grain-discharging short tube put grain sack realize pack.But this foodstuff bagging machine is piled between pack from grain to be needed through suction tank, grain output device, then enters high-order silo, and the process in the middle of this is longer, and step is more, and the loss of energy is more on the one hand, and the specification of the blower fan used is larger; Grain is after the Cemented filling through very long complications on the other hand, understands some grain and remains in pipeline, and the time one is long, causes the cleaning difficulty of pipeline; Parts related in one aspect to again or more, keep in repair cumbersome.

2) and, this apparatus structure is simple, and amount of parts is few, and cost is low;
3) under the effect driving cylinder, hopper directly can shovel out grain and directly pour in loading bag from grain heap, therefore, greatly enhances productivity;
4) after hopper port has added baffle plate, put in place in hopper upset and carry out there has been stop when toppling over grain, avoid the phenomenon that loading bag poured out by grain in toppling process occurs;
5) hopper is used for shoveling one end of grain and is designed to angle, is to can better more effectively shovel in material bin by grain;
6) base designs is packaged type, makes this device more flexible, can move to the bagging operations carrying out grain Anywhere.
