Problems solved by technology

[0003] The present invention aims to solve the problem that the existing grain cleaning machine has only one large sieve box, which causes the grain cleaning machine to resonate when it is working, causing the whole body to vibrate, which affects the service life of the machine, and the sieve box is an integrated structure and cannot be realized. The problem of accurate grading of grain; and then a kind of grain cleaning machine with double sieve box is provided

specific Embodiment approach 1

[0007] Specific implementation mode one: as figure 1 and figure 2 As shown, the grain cleaning machine with double sieve boxes in this embodiment includes a frame 21, a grain feeding container 17, a specific gravity box 18, an induced draft fan 19, a blower 20, a motor 24, an induced draft fan transmission mechanism 27 and a blower transmission mechanism 28. The specific gravity box 18 is installed on the frame 21, and the grain feeding container 17 is arranged on the upper end of the specific gravity box 18. The induced draft fan 19 and the blower 20 are respectively driven by the output shaft of the induced draft fan transmission mechanism 27, the blower transmission mechanism 28 and the motor 24. Connection, the induced draft fan 19 and the blower 20 are all located under the specific gravity box 18, the induced draft fan 19 is installed on the frame 21 and communicates with one end of the specific gravity box 18, and the blower fan 20 is installed on the frame 21 and conn...

specific Embodiment approach 2

[0009] Specific implementation mode two: as figure 1 and figure 2 As shown, the fourth connecting rod 9 in this embodiment is a curved rod, and the bending point of the curved rod is hinged to the frame 21 at the corresponding position. The fourth connecting rod 9 is designed as a bent rod, and when the upper end of the fourth connecting rod 9 swings slightly, its lower end will swing at a larger angle. Other components and connections are the same as those in the first embodiment.

Abstract

A dressing machine having double straining boxes relates to a dressing machine. The invention solves the problem that sympathetic vibration is generated in work as the existing dressing machine has only one straining box so that the service life of the machine is influenced and exact classification of grain cannot be realized. An upper straining box and a lower straining box are installed from top to bottom and a gap remains between the two straining boxes; both ends of two lateral walls of the upper straining box and the lower straining box are respectively connected via a first swing stem and a second swing stem, and the middle parts of the first swing stem and the second swing stem are connected with machine frames at corresponding positions; each cam is fixedly connected with one end of a first connecting bar, the other end of the first connecting bar is connected with the middle part of a third connecting bar, one end of the third connecting bar is connected with one end of the second connecting bar, the other end of the third connecting bar is connected with one end of a fourth connecting bar, the other end of the fourth connecting bar is connected with one end of a fifth connecting bar, and the other end of the fifth connecting bar is connected with the lateral wall of the lower straining box. The invention uses two straining boxes so that the dressing machine has better balance performance without generating sympathetic vibration, thereby improving the service life of the dressing machine.

Description

technical field [0001] The invention relates to a grain cleaning machine. Background technique [0002] The grain cleaning machine is used to clean grain, select seeds and grade the harvested crops, such as wheat, king rice, bean crops and other agricultural products. There is only one large sieve box in the existing grain cleaning machine (that is to say, the sieve box is an integrated structure), so that when the grain cleaning machine is working, it is easy to cause the body to be unbalanced, generate resonance, and cause the whole body to vibrate, which greatly affects The service life of the machine is shortened; and the sieve box is an integrated structure and cannot achieve accurate grading of clear grain. Contents of the invention [0003] The present invention aims to solve the problem that the existing grain cleaning machine has only one large sieve box, which causes the grain cleaning machine to resonate when it is working, causing the whole body to vibrate, wh...
