Summary of the invention
The utility model is low for the sifter automaticity that has hand-rail type of prior art, and the screening frequency is unfixing, can not get rid of the problem of screening frequency on the impact of experimental result, proposes a kind of soil agreegate automatic sieving device.
The technical solution of the utility model is: a kind of soil agreegate automatic sieving device, comprise support, bent axle, the collar, native screen frame (unit) and soil sieve, be provided with the bearing holder (housing, cover) of two symmetries on the closed-loop of support the top, bent axle is connected with the bearing on support by bearing, the support ring of mid-stent is provided with a fairlead, have at least three horizontal struts to be fixedly connected with support ring with fairlead, the threaded rod of collar the latter half is through fairlead; The soil screen frame (unit) is hinged by connecting rod and the collar and bent axle, described native screen frame (unit) is comprised of the fixing soil sieve ring holder of door type framework and lower end, on door type framework, the end floor beam middle part is provided with a thread bush, the soil screen frame (unit) is connected and fixed by thread bush and connecting rod, it is upper that soil sieves the soil sieve ring holder that is placed in native screen frame (unit) lower end, and an end of described bent axle is connected with engine.
Described soil agreegate automatic sieving device, described engine is variable-frequency motor, the rotating speed of variable-frequency motor is set to 20 rev/mins～30 rev/mins.
Described soil agreegate automatic sieving device, described engine is common electric machine, and motor is connected with an end of bent axle by decelerator, and the rotating speed after deceleration is 25 rev/mins.
Described soil agreegate automatic sieving device, the described collar is connected together by two approximate circle ring sets, draws separately the mechanism with break-in function of the structure composition of an external thread rod.
The beneficial effects of the utility model are: soil agreegate automatic sieving device of the present utility model divides and compares with rider, have easy to use, reduce error, save the operating time, reduce personnel labor intensity and the advantage such as increase work efficiency; In addition, adopt the variable-frequency motor driving crank, can set the rotating speed of bent axle by the rotating speed that variable-frequency motor is set, guarantee stability and the accuracy of screening frequency, avoid sieving frequency inconsistent, the result of impact experiment; Be provided with support ring in mid-stent in addition, the fairlead arranged on support ring, avoid the connecting rod horizontal jitter, guarantees that the screening frame vertically moves up and down.
