In the figure: 1. the automatic pin-driving device comprises a shell, 2 parts of guide rails, 3 parts of sliding blocks, 4 parts of servo motors, 5 parts of nut screw assemblies, 6 parts of transmission shafts, 7 parts of cross beams, 8 parts of shaft seats, 9 parts of shafts, 10 parts of barbed nail rollers, 11 parts of grid bars and 12 parts of lifting rods.

Detailed Description

because the spacing adjustment mechanism that is applicable to the spacing adjustment between spike roller set and grid bars group is the minor change of making in production practice, only provide an attached drawing and can clarify the utility model discloses a design. Although the smaller modification is smaller than the equipment per se, the influence on the cleaning function of the seed cotton cleaning machine is larger.

In addition, as the cotton matching vehicle is the development direction of the current cotton processing machinery, the online adjustment of the working parameters of the cotton processing equipment is the main development direction.

At present, the main factor of cotton matching is embodied in the cotton gin, and the seed cotton cleaning machine has not much attention, and the seed cotton cleaning is relatively extensive mainly because the primary cleaning is carried out on heavy impurities, dust, broken cotton leaves and the like, and the relatively extensive working mode easily causes the neglect of technicians in the field.

As described in the background section, an important working parameter of the seed cotton cleaning machine is the distance between the spike roller set and the grid set, and the distance in the existing seed cotton cleaning machine is fixed and cannot be adjusted according to the properties of seed cotton, so that the purpose of vehicle distribution due to flowers cannot be achieved.

while fig. 1 shows a horizontal seed cotton cleaner, it will be understood that the same applies to the inclined seed cotton cleaner, and that the adjustment of the spacing between the two types of seed cotton cleaners is a linear adjustment, which is not different.

in fig. 1, six spike rollers 10 are provided, six spike rollers 10 are collectively referred to as a spike roller group, and in addition, six grid bars 11 are provided corresponding one-to-one to the spike rollers 10, and in the structure shown in fig. 1, the grid bars 11 are located below the spike rollers 10, and heavy impurity discharge from the grid bars of the grid bars, for example, can be performed based on gravity.

for example, the inclined seed cotton cleaner disclosed in the Chinese patent document CN204849154U does not change the basic pattern that the barbed nail roller 10 is arranged above and the adapted grid 11 is arranged below.

for the convenience of description, it is noted that the plane defined by the coplanar axes of the spike rollers 10 in the spike roller set is a base plane, such as the horizontal plane passing through the axes of the spike rollers 10 in fig. 1, and is represented as an inclined plane passing through the axes of the spike rollers in chinese patent document CN 204849154U.

Accordingly, the grid set, whether in a horizontal seed cotton cleaner or an inclined seed cotton cleaner, is located on the underside of the base plane, which side is designated as the first side.

The axle seat 8 direct mount of traditional seed cotton descaling machine is on the casing 1 of seed cotton descaling machine, specifically on the wallboard, and the rigidity can't be adjusted.

in the construction shown in fig. 1, a cross beam 7 is provided as a seat, the cross beam 7 being parallel to the material conveying direction of the seed cotton cleaning station of the seed cotton cleaning machine or to the arrangement direction of the spike roller sets, the cross beam 7 serving as a support for the spike roller shafts of the spike roller sets, which spike roller shafts are shafts 9 in fig. 1, the shafts 9 being mounted on the cross beam 7 via bearing blocks, i.e. shaft seats 8 shown in fig. 1.

And the nut can be assembled with a bevel gear into a whole to serve as a driven gear, and the driving bevel gear is arranged on the transmission rod and meshed with the driving bevel gear to drive a screw nut screw mechanism on the right side. The screw nut and screw mechanism on the left side has the same principle.

in the structure shown in fig. 1, two ends of the spike roller 10 are provided with shaft seats 8, and the shaft seats 8 are fixed on the cross beam 7;

guide rail assemblies in the normal direction of the base plane are arranged corresponding to two ends of the cross beam 7, and the end part of the cross beam 7 is fixed on the sliding block 3 of the guide rail assembly at the end.
