Abstract

The utility model relates to a grain drier which is a drying apparatus used for drying grain in agricultural machinery. An air feed and an air discharge angle-shaped pipes in a drying section and a cooling section are arranged and fixed in a cross structure. Refracting plates are arranged at four corner points of the drying section and the cooling section. A grain discharge mechanism composed of an upper sliding plate, a lower arc plate, a self-cleaning rotor and a discharge hopper is uniformly arranged on the whole cross section of a grain discharge section along the horizontal direction. The self-cleaning rotor can rotate along the obverse and the inverse directions. A high temperature air pipe is arranged in a low temperature wind chamber. The drier has the advantages of simple structure, strong rigidity and strength of the whole drier, energy and manufacturing material saving and low crushing rate. Dried grain has even water content and good quality.

Description

Crop dryer

The utility model belongs to the drying machinery that is used for grain and baked seed use in the agricultural machinery.

Agricultural production practice for many years proves, to grain or breeding dehydrate be guarantee its quality, one of the effective measures of product interchange of doing business of going forward side by side.Current, the crop dryer tool is of a great variety, and wherein the drying machine with the angular tube class formation uses comparatively extensive.Since its drying effect still can, in agricultural byproducts processing, played positive role.But, because the inlet and outlet angular tube of this drier adopts the fixed structure that is arranged in parallel on same direction, therefore the grain that is dried during operation mixes inhomogeneous, the body intensity difference, certainly lead to the unfavorable problem of drying effect, when precipitation range 10% when above, the moisture difference of oven dry back grain is generally 3～5%; Secondly, the high and low temperature air channel is the design of separate configurations separately, has wasted insulation material, has increased manufacturing cost, and the thermal loss in high temperature air channel causes a large amount of energy wastes, seems more outstanding in northern China extremely frigid zones contradiction especially; The 3rd, be provided with grain dividing plate in the grain discharging section, complex structure, and two screw feeders in both sides concentrate row's grain to cause row's grain inhomogeneous (also being to cause one of irregular reason of oven dry), and vibration row grain structural reliability is poor, percentage of damage is greatly its deadly defect, especially behind roasted grain, be not easy cleaning, cause miscegenation.

The purpose of this utility model is exactly on existing angular tube structure dryer basis, design a kind of crop dryer that is more suitable in grain-drying, make it when drying grain or kind subjob, grain that is dried in the assurance machine or seed can overturn fully in top-down flow process, mix, parallel even whereabouts and clear grain are convenient, to reach the purpose that improves oven dry uniformity (can reach in 1%), strengthens crop dryer tower body rigidity and intensity, saving manufactured materials and energy savings.

Basic design of the present utility model is air inlet angular tube in oven dry section and the cooling section and exhaust angular tube are criss-cross construction alignment arrangements, fixing, and portion to install the angle deflecting plate in four jiaos of places within it; Grain discharging section is made of upper slide, lower curved plate, certainly clear rotor, dump skip, and it can realize positive and negative both direction rotation from clear rotor; The high temperature airduct adopts and to be configured in the low temperature air compartment, the structure that is communicated with the high temperature air compartment again, and the low temperature air compartment is provided with the rock wool heat-preservation layer.

The utlity model has that cereal moisture content after the oven dry is even, dries quantity good, percentage of damage is low, the clear grain of facility is convenient, save the energy and manufactured materials, simple in structure, complete machine rigidity and the good characteristics of intensity.

Fig. 3 is the grain discharging section structural representation;

Fig. 4 is the partial enlarged drawing of Fig. 3;

Fig. 5 is high temperature airduct, low temperature air compartment, high temperature air compartment and rock wool heat-preservation layer configuration relation schematic diagram.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Crop dryer is assemblied by grain storage section 1, oven dry section 2, cooling section 3, grain discharging section 4, low temperature air compartment 5 and high temperature air compartment 6.Air inlet angular tube 7 in oven dry section 2 and cooling section 3 is the right-angled intersection alignment arrangements with exhaust angular tube 8 to be fixed, and in oven dry section 2 and cooling section 3 inner four jiaos of places angle of entry deflecting plate 9 is installed.8 groups of draining crop mechanisms that constitute by upper slide 10, lower curved plate 11, from clear rotor 12, dump skip 13 make from clear rotor 12 by positive and negative start button and machine driving on the control panel and realize positive and negative both direction rotation smoothly along horizontal direction, configuration is installed on the entire cross section of grain discharging section 4 equably.High temperature airduct 15 is configured in the low temperature air compartment 5, is communicated with high temperature air compartment 6 again, constitutes compound air duct, in the design of the outside of low temperature air compartment 5 rock wool heat-preservation layer 14 is arranged.During the cereal drying operation, cereal flows from top to bottom in crop dryer inside, under inlet and outlet angular tube 7,8 effects of right-angled intersection configuration, overturn fully, mix, form rationally, paddy layer thickness equably, thereby improved the uniformity of grain-drying greatly, simultaneously, the inlet and outlet tubulose pipe 7,8 that right-angled intersection is arranged has improved the rigidity and the intensity of tower body as the lacing wire in the body; Angle deflecting plate 9 has been eliminated the dead angle of cereal in flowing; When 8 groups of draining crop mechanisms of horizontal arrangement are arranged grains in the grain discharging section 4, rotate from clear rotor 12 whole forwards (clockwise), strengthened row's grain uniformity, when drying operation finishes to carry out clearly grain, rotate from clear rotor 12 revert alls (counterclockwise), utilize from clear rotor 12 and lower curved plate 17 minimum fit clearances and realize clear grain operation; Hot blast enters in the crop dryer tower body by high temperature air compartment 6 and low temperature air compartment 5, and high temperature airduct 15 is positioned at low temperature air compartment 5, has reduced and reduced the radiation loss of heat, and high temperature airduct 15 dispersed heats are all entered in the low temperature air compartment 5.
