Abstract
The utility model discloses a preliminary cleaning sieve for a winnowing drum, which relates to a preliminary cleaning sieve for separating paddy from rice straws and weed. The winnowing drum preliminary cleaning sieve is mainly used for solving the problems that a known preliminary cleaning sieve can enable the paddy to fall from holes of a sieve mesh of a sieve barrel through the rotation of the sieve barrel, and the rice straws and the weed are brought into a residue discharge port through the rotation of a spiral propeller, so that the speed is slow, and the small weed can simultaneously fall with the paddy through the holes of the sieve. The preliminary cleaning sieve comprises a machine body, the sieve barrel, a feeding pipe and the spiral propeller, wherein the sieve barrel and the feeding pipe are fixed on the machine body, and the spiral propeller is fixed in the sieve barrel. The preliminary cleaning sieve is characterized in that a blower is arranged at the feeding end of the sieve barrel. As the blower is arranged at the feeding end of the sieve barrel, the speed of enabling the rice straws and the weed to enter into the residue discharge port from the spiral propeller is accelerated, and the small weed is simultaneously blown away by wind, so that the rate of separating the paddy from the rice straws and the weed is ensured and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of cylindrical receiving sieve, relates to a kind of a kind of receiving sieve that paddy is separated with rice bar and weeds specifically.
Background technology
Known paddy rice is after the thresing machine threshing; Also be mixed with a large amount of rice bar and weeds in the paddy, for paddy is separated from rice bar and weeds, the first cylindrical that jigged that uses at present just jigs; Rotation through the sieve bucket falls paddy from the screen cloth eye of sieve bucket; Rice bar and weeds are brought slag notch into through the spiral propeller in the sieve bucket and discharge, and be brought into slag notch because rice bar and weeds are rotations through spiral propeller, so speed are slow; Also have tiny weeds to fall with paddy simultaneously, paddy is separated with weeds totally through the mesh on the sieve bucket; In addition, the sieve bucket adopts two motors to carry out transmission, wastes energy.
Summary of the invention
The purpose of the utility model is to above-mentioned deficiency, and a kind of can paddy the separation with weeds with the rice bar fully that proposes, work efficiency is high, the selection by winnowing drum receiving sieve of energy savings.
The technical solution of the utility model is: the receiving sieve of selection by winnowing drum comprises body, is fixed on sieve bucket and feed pipe on the body, and is fixed on the spiral propeller in the sieve bucket, it is characterized in that: the end in the charging of sieve bucket is provided with blower fan.
The air outlet of the blower fan described in the technical solution of the utility model is connected on the feed pipe, perhaps on the discharging opening of feed pipe.
On the circumference of the sieve bucket described in the technical solution of utility model through two driving wheels and two driven pulley transmissions, between two driving wheels through chain drive.
The utility model is owing to increased by a typhoon machine on the feed pipe; After the paddy that is mixed with rice bar and weeds gets into the sieve bucket from charging aperture; Under the effect of blower fan, quickened the speed that rice bar and weeds get into slag notch from spiral propeller, tiny weeds are also blown away by blower fan simultaneously; Guarantee the separation rate of paddy and rice bar and weeds, improved work efficiency simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, the utility model comprises body 2, is fixed on the sieve bucket 4 on the body 2; And be fixed on the spiral propeller 8 on sieve bucket 4 inwalls, and being provided with feed pipe 1 at sieve bucket 4 end vertically, the outlet of feed pipe 1 is located on sieve bucket 4 charging apertures; Below along the axial other end of sieve bucket 4 is provided with slag notch 9, and feed pipe 1 is fixed on the body 2, is provided with blower fan 5 at an end of sieve bucket 4 chargings; Can the air outlet of blower fan 5 be connected on the feed pipe 1; Also can the air outlet of blower fan 5 be connected on the discharging opening of feed pipe 1 lower end, below sieve bucket 4, be provided with discharging opening 10, above body 2, be provided with dust-exhausting port 3; Drive 4 rotations of sieve bucket through four drives on the circumference of sieve bucket 4, wherein two is that 7, two of driving wheels are driven pulley 11, and one of them driving wheel 7 is connected with motor through gear-box 6, connects through chain drive between two driving wheels 7; During work; At first motor drives 4 rotations of sieve bucket through reducing gear; The paddy that is mixed with rice bar and weeds gets in the sieve bucket 4 from feed pipe 1; Paddy falls into discharging opening 10 from the screen cloth eye on the sieve bucket 4, and rice bar and weeds are discharged outside the sieve bucket 4 at the slag notch below sieve bucket 49 under the acting in conjunction of blower fan 5 and spiral propeller 8.
