Compared with the prior art, the invention has the following advantages:

1. the automatic feeding device is used as an important component of the automatic feeding system for the uranium chemical concentrated materials, is used for driving the charging basket to enter or move out the charging basket overturning device of the automatic feeding system for the uranium chemical concentrated materials along a limited path, and lays a foundation for realizing the automatic feeding operation of the uranium purification concentrated materials. The charging basket enters the charging basket overturning device so as to facilitate the subsequent charging basket overturning operation, and the charging basket moves out of the charging basket overturning device so as to facilitate the crane to hoist and transport the charging basket away.

2. The storage bucket that contains uranium chemical concentrate material usually weighs more than 1 ton, bears the weight of the frame (the storage bucket bears the weight of the frame and places on travelling car A through the storage bucket promptly) through setting up the storage bucket between storage bucket and travelling car A, can be fine with storage bucket weight share to travelling car A's a plurality of cylinder A on, avoid the weight of storage bucket excessively concentrate on a few cylinder A, and bend cylinder A.

3. Operating personnel puts down the in-process that bears on the storage bucket through driving control storage bucket, and the wheel C of rectifying on two deviation wheel carriers C and the storage bucket bear four group's locating wheel A on the frame and can roll contact with the storage bucket outer wall, play jointly and prevent that the storage bucket from rocking, for the storage bucket effect of providing the direction of transferring, in addition, the proof warp pole on the mounting bracket stretches into in the jack that the storage bucket bears the frame and can avoid the storage bucket to bear the frame and knock the turnover because of rocking the storage bucket.

4. The four groups of positioning wheels A form a charging bucket positioning arc bend A together, the two rows of positioning wheels B form a charging bucket positioning arc bend B together, and the charging bucket positioning arc bend A and the charging bucket positioning arc bend B enclose to form a charging bucket positioning area. When the piston rod of pneumatic cylinder stretched out, promoted the storage bucket and removed, storage bucket location arc A and storage bucket location arc B laminated the storage bucket outer wall from the storage bucket both sides respectively, and then with the accurate restriction in the storage bucket location region in position of storage bucket, ensured the accuracy nature of storage bucket removal route.

5. The sliding frame is arranged between the hydraulic cylinder and the charging basket bearing frame, and the hydraulic cylinder pushes the charging basket on the charging basket bearing frame to move sequentially through the sliding frame, the positioning wheel seat B and the positioning wheel B. On the one hand, the end of the piston rod of the sliding frame and the hydraulic cylinder is connected, so that the problem that the piston rod of the hydraulic cylinder is sagged under the action of self weight and then the piston rod of the hydraulic cylinder is abraded at the lower end is effectively avoided. On the other hand, because the position that the storage bucket was originally placed on the storage bucket bears the frame has certain randomness, the storage bucket center can not guarantee with the central line coincidence of the piston rod of pneumatic cylinder, when initial promotion storage bucket, the storage bucket can move to the position with the central line coincidence from the position of skew central line, and in this process, the locating wheel B atress of locating wheel seat B one side is greater than the locating wheel B of opposite side, and the locating wheel B atress of locating wheel seat B both sides is unbalanced promptly. The sliding frame arranged between the hydraulic cylinder and the charging basket bearing frame can effectively bear the unbalanced force, the unbalanced force is prevented from being transmitted to the piston rod of the hydraulic cylinder, the piston rod of the hydraulic cylinder is guaranteed to smoothly extend out and retract, and the problem of unilateral blocking is avoided.

6. The sliding frame is movably arranged on the two sliding rails through the rollers at the lower end of the sliding frame, and is limited between the two guide surfaces of the sliding frame deviation preventing component. Because the position that the storage bucket was originally placed on the storage bucket bears the frame has certain randomness, the central line coincidence with the piston rod of pneumatic cylinder can not be guaranteed at the storage bucket center, when the storage bucket is promoted at the beginning, the storage bucket can be followed the position of skew central line and moved to the position with the central line coincidence, this in-process, the locating wheel B atress of locating wheel seat B one side is greater than the locating wheel B of opposite side, the balladeur train both sides atress is unbalanced promptly, the skew trend appears when leading to the balladeur train to remove, and then lead to the gyro wheel card to die in the slide rail. And two guide surfaces of the sliding frame deviation preventing assembly well play a role in limiting the moving path of the sliding frame, the effect of correcting the deviation trend of the sliding frame in real time is achieved, and the sliding frame is ensured to move smoothly along the sliding rail.

The automatic feeding system for the uranium chemical concentrated materials has the following advantages that:

the automatic feeding operation of the radioactive uranium-containing chemical concentrated material can be realized, the stability, reliability and automation degree of the feeding process are higher, and the feeding effect is clean and thorough; the feeding operation can be executed by only 1 operator, so that the labor intensity of the operators is reduced, and the time for the operators to receive radioactive radiation in a short distance is shortened; need not to have the component of locating hole at the storage bucket bottom welding of splendid attire concentrated material, be favorable to the simplification of storage bucket structure, reduced the manufacturing cost of storage bucket.
