Description
Technical Field
[0001] The utility model relates to the technical field of seed processing, and particularly relates to a device for adjusting the swing amplitude of a sieve box of a pneumatic-sieve cleaner. Background Art
[0002] The pneumatic-sieve cleaner is a common seed or grain cleaning device, which mainly uses the differences in geometric dimensions, aerodynamic characteristics, etc. between seeds and inclusions for cleaning and winnowing. Its working principle is generally as follows: after the material enters the machine, it first passes through the winnowing part, and the light impurities are removed by the airflow; then the material enters the vibrating sieve part. According to the external dimensions of the granular material, sieve plates of appropriate specifications are configured, and under the reciprocating movement of the sieve plates, impurities of different sizes are further separated.
[0003] The pneumatic-sieve cleaner has the following characteristics and advantages: it can perform size sorting and weight sorting on seeds, effectively remove impurities, and improve the purity of seeds or grains. Appropriate sieve plates can be replaced according to different crops and cleaning requirements to achieve the cleaning of various crops. It has the characteristics of small floor area and relatively simple operation. The pneumatic-sieve cleaner is widely used in seed companies, farms, and good seed propagation departments at all levels, and can be used for the primary selection and basic cleaning of seeds of various crops such as wheat, corn, rice, and soybeans.
[0004] Inside the vibrating sieve part of the pneumatic-sieve cleaner, the vibrating motor is generally installed and fixed on the sieve box. When the sieve box is assembled into the vibrating sieve, there are installation errors between it and other components. During the debugging process, the vibrating motor and the sieve box are prone to unstable vibration. However, since the vibrating motor is installed and fixed on the sieve box, it can only be disassembled from the sieve box and then reinstalled and fixed, and then debugged again. In practice, it needs to be disassembled, installed, and debugged repeatedly for many times, which is very cumbersome and wastes a lot of time. In addition, due to different types of crop seeds and inclusions, it is necessary to adjust the swing amplitude of the sieve box in necessary cases. The adjustment of the swing amplitude of the sieve box is generally achieved by adjusting the amplitude of the vibrating motor. After adjusting the amplitude of the vibrating motor, it is necessary to adjust the attitude of the vibrating motor to ensure stable vibration. Therefore, it is necessary to provide a device with convenient adjustment of the installation position of the vibrating motor, adjustable amplitude of the vibrating motor and swing amplitude of the sieve box.

[0007] By adopting the above technical solutions, when the wind sieve type cleaning machine is installed and debugged or the amplitude of the vibration motor is adjusted, when it is necessary to debug the installation position of the vibration motor, loosen the locking bolt and the positioning bolt, remove the sliding seat, then slightly loosen the locking bolt, rotate the mounting seat to adjust the position of the vibration motor on the sieve box, and tighten the locking bolt to fix the position of the mounting seat and the vibration motor. At this time, start the vibration motor to test the vibration stability.

[0012] A further setting of the utility model is that the support includes a base and a first seat body fixed on the base, and the sliding hole is located on the first seat body.
[0013] A further setting of the present utility model is that the support further includes a second seat body fixed on the base, and the positioning bolt is threadedly connected to the second seat body.

[0017] A further setting of the present utility model is that the positioning column is in a cylindrical shape.
[0018] The beneficial effects of the present utility model are as follows: By installing the vibration motor on the mounting seat, and installing the mounting seat on the sieve box through the arc-shaped groove, locking bolt and first threaded hole, the position of the mounting seat can be adjusted by loosening the locking bolt, so as to adjust the installation angle of the vibration motor.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.
[0025] An adjustable device for the swing amplitude of the sieve box of a wind-sieving cleaner, as Figures 1 to 3 shown, includes a sieve box 1, a mounting seat 2, a vibration motor 103 mounted on the mounting seat 2, and two locking bolts 4. Two arc-shaped grooves 21 are provided on the mounting seat 2. The two locking bolts 4 respectively correspond to the two arc-shaped grooves 21. Two first threaded holes are provided on the sieve box 1. The two locking bolts 4 respectively pass through the two arc-shaped grooves 21 and are threadedly connected in the first threaded holes. The mounting seat 2 is in a disc shape.
[0026] Two guide rails 5 are fixed on the sieve box 1, and the mounting seat 2 is located between the two guide rails 5. Two sliders 51 are slidably connected to each guide rail 5. A support 6 is fixed on each slider 51. The support 6 includes a base 61, a first seat body 62, and a second seat body 63. The first seat body 62 and the second seat body 63 are both fixed on the base 61. A positioning bolt 8 is threadedly connected to the first seat body 62. A sliding hole is provided on the second seat body 63. A sliding seat 7 is inserted into the sliding hole. The cross-section of the sliding hole and the cross-section of the sliding seat 7 are both rectangular. One end of the sliding seat 7 abuts against the positioning bolt 8, and a positioning groove 71 is provided at the other end. The positioning groove 71 is arc-shaped. Two positioning columns 22 are fixed on the mounting seat 2. The positioning columns 22 are cylindrical. Each positioning column 22 is embedded in the positioning grooves 71 of the two sliding seats 7. By locking the position of one positioning column 22 by the two sliding seats 7, the position of the mounting seat 2 is further locked.
[0027] When the wind-sieving cleaner is installed and debugged or the amplitude of the vibration motor 103 is adjusted, when it is necessary to debug the installation position of the vibration motor 103, loosen the locking bolt 9 and the positioning bolt 8, remove the sliding seat 7, then slightly loosen the locking bolt 4, rotate the mounting seat 2 to adjust the position of the vibration motor 103 on the sieve box 1, and tighten the locking bolt 4 to fix the positions of the mounting seat 2 and the vibration motor 103. At this time, start the vibration motor 103 to test the vibration stability.
[0028] During the long-term operation of the air-screen cleaner, if the mounting base 2 is only locked by the locking bolts 4, it is very easy for the locking bolts 4 to become loose and the position of the mounting base 2 to become loose. After the vibration of the sieve box 1 stabilizes, turn off the vibration motor 103 at this time, install the sliding seat 7, lock the positioning column 22 through the positioning grooves 71 on the two sliding seats 7, lock the position of the sliding seat 7 through the positioning bolts 8, and lock the position of the support 6 through the locking bolts 4, so as to realize the position locking of the mounting base 2.
[0029] By adjusting the amplitude of the vibration motor 103, the function of adjusting the swing amplitude of the sieve box 1 can be realized. To adjust the amplitude of the vibration motor 103, several counterweights can be installed on the eccentric block of the vibration motor 103, and the amplitude can be adjusted by changing the number of counterweights.
