Detailed Description

For ease of use, embodiments of the present invention provide a leveling device. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the examples of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

This embodiment provides a levelling apparatus which will be described in detail below in terms of the direction of tea input, as illustrated with reference to figures 1 and 2.

Firstly, a tea leaf input mechanism is arranged, in the figure, an inclined plane feeder 1 is arranged at an input end, and feeding is carried out at the bottom to a uniform stacking platform. The end of the inclined plane feeder 1 is connected with a section of plane feeder 2, the output end of the plane feeder 2 is provided with a material conveying travelling crane, and the material conveying travelling crane is arranged above the uniform stacking bin 4 and conveys tea leaves to the uniform stacking bin to lay a longitudinal tea pile.

It should be noted that the tea leaf is laid by the delivery vehicle shown in the figure in this embodiment, but in another preferred embodiment, the delivery operation of the leveling silo 4 is performed by connecting the delivery vehicle by a pipeline or other conventional means, and it is within the scope of the present invention.

And with the attached drawing, the specific scheme of the material conveying travelling crane is that a transverse travelling crane 3 and a longitudinal travelling crane 5 are arranged at different heights. The transverse traveling crane 3 is arranged above the longitudinal traveling crane 5, and the transverse traveling crane 3 receives the tea leaves from the plane feeding machine 12 and finally conveys the tea leaves to the longitudinal traveling crane 5.

The transverse row 3 can slide back and forth along the transverse direction (i.e. up and down on the paper of fig. 2) to realize the conveying of the tea leaves at different transverse positions on the longitudinal row 5. It is worth mentioning that in order to utilize the sliding path of the transverse traveling crane 3 to the maximum extent, referring to fig. 2, cloud storage bins 4 are arranged on both sides of the transverse traveling crane 3, and the longitudinal traveling cranes 5 of the two cloud storage bins 4 are butted with the transverse traveling crane 3. The transverse travelling crane 3 is provided with a conveyor belt capable of rotating forward and backward, so that the two longitudinal travelling cranes 5 can be conveyed. For example, when the material is discharged after the material is completely conveyed in the uniform stack bin 4, the transverse traveling crane 3 can convey the material in the cloud stack bin 4 on the other side, so that the integral production beat is accelerated, and the production efficiency is greatly improved.

The longitudinal traveling carriage 5 is mounted above the level stack compartment 4 in the drawing, and is driven to slide back and forth in the longitudinal direction (i.e., the left and right direction of the sheet of fig. 2). In operation, tea leaves of the traversing carriage 3 are received and finally laid in the levelling and piling bin 4.

Detailed description of the preferred embodimentreferring to fig. 3, if a blended tea is desired, the tea includes 3 teas, A, B, C, in a 3:2:2 weight ratio. Then 3 longitudinal tea piles are required to be laid according to the planned A kinds of tea leaves, corresponding to the first position, the second position and the third position in the

longitudinal travelling crane

5, and 2 longitudinal tea piles are required to be laid for B and C, namely the fourth position, the fifth position, the sixth position and the seventh position.

Feeding is started according to planning, firstly, A tea leaves are put into a conveyor and enter a transverse travelling crane 3 along an integral conveying line, the transverse travelling crane 3 slides the output position of the transverse travelling crane to a position above a position of a longitudinal travelling crane 5 and then stops, a conveying belt on the longitudinal travelling crane 3 feeds the uniform stacking bin 4 and integrally slides at the same time, when the transverse travelling crane slides to a position half the length of the uniform stacking bin 4, the conveying belt reversely rotates to feed towards the other half, when the longitudinal travelling crane 3 reaches the limit position of the uniform stacking bin 4, the conveying belt reversely rotates again, and the self moving direction of the longitudinal travelling crane 3 reversely feeds until the longitudinal travelling crane returns to the bottom of the uniform stacking bin 4 to form a complete longitudinal tea pile. And then the tea pile is moved repeatedly in a cycle, the complete longitudinal tea piles are driven at the positions of the second and third machines, and at the moment, the three longitudinal tea piles of the A type of tea leaves are paved. Meanwhile, the end of the conveyor is continuously fed, namely, after all the A kinds of tea leaves are put into the conveyor, the B kinds of tea leaves are immediately connected, and finally, the C kinds of tea leaves are connected, so that the tea leaves are continuously put into the conveyor.

And after the longitudinal tea pile laying of the tea leaves of the A type is finished by the material conveying travelling crane, the longitudinal tea pile laying of the tea leaves of the B type and the tea leaves of the C type is also carried out immediately according to the same working procedure.

The final effect is that A, B, C three kinds of tea are made into tea piles in the same proportion in the homogenizing silo 4 according to the proportion of the formula. Then the conveyor belt in the uniform stacking bin 4 pushes the uniform stacking bin 4 out, and a discharging rake is arranged at the output end of the uniform stacking bin 4 and used for discharging in a vertical cutting mode. During the period that the discharging harrow pulls down tea leaves, three kinds of tea leaves are uniformly mixed, each longitudinal tea pile is parallel and level in the longitudinal direction, just like parallel arranged 'noodles', and each harrow comprises the blended tea according to the proportion of the formula.

In the whole process, the most important link is the calculation of the longitudinal tea pile of the blended tea when the tea leaves are not input. The technical details here also represent the advancement of the longitudinal tea-heap solution of the present invention. No matter what method is adopted for even stacking, the uniformity is realized, and the premise for solving the technical problem is to carry out blending according to the formula process. The method of the longitudinal tea pile of the invention is adopted to carry out process design through the number of the tea piles intuitively, and the quantity of the tea in each tea pile can form a stable constant through designing the speed of the material conveying travelling crane, thus not causing too large error to the calculation of the result. Each tea pile is relatively independent in space through the design clearance, namely when laying the second tea pile, can not receive the influence of other tea piles. If a multi-layer laying mode is adopted, compared with the phenomenon that the tea leaves like bulk materials collapse between layers, the uniformity of each layer of tea leaves is difficult to ensure. Furthermore, if the number of longitudinal tea piles is too large and the lateral distance is not enough, the tea piles can be stacked upwards on the basis of the first layer of tea piles, and in view of the scheme of the longitudinal tea piles, the flexibility is higher, and the adjustable range is larger in use.

It should be noted that, in the design of the present embodiment, the above technical key is fully considered. The planar conveyor 2 is provided with a belt scale and a controller, and the speed of the planar conveyor 2 is controlled by the controller through the feedback of the belt scale to control the flow rate, so that the amount of the longitudinal tea piles is controlled.

The idea of the design is to control the number of tea piles by controlling the real-time flow into the homoheap bin 4. In another preferred embodiment, a combination of a belt scale and a controller can be used to control the output flow of the delivery wagon (as can be achieved at the input end of the levelling bin 4) and also to control the number of longitudinal tea piles. However, in this embodiment, since the transporting vehicle is moving, in order to reduce the variation and the stability of the operation, the speeds of the transverse vehicle 3 and the longitudinal vehicle 4 in the transporting vehicle are fixed to be a constant.

Further, another reason for setting the speed variable on the flat conveyor 2 is that, if the flow rate in the current conveying step is to be controlled, it is necessary to ensure that the flow rate in the previous step is sufficient, that is, the previous step is kept to feed continuously, whereas in the case of the current conveying mechanism, the feeding is performed by dumping, and a large amount of feeding can be performed as long as the conveyor speed is sufficient. In other words, then, the speed before the step of controlling the flow rate must be higher than the speed of the current step. Therefore, in an advantageous scheme, the flow rate of the plane conveyor is controlled only by controlling the speed of the inclined plane conveyor to be higher than that of the plane conveyor. If the control step is set on the conveying traveling crane, it is necessary to ensure that the speed of the plane conveyor 2 is higher than that of the traveling crane and the speed of the inclined plane conveyor is higher than that of the plane conveyor, which increases the running cost and reduces the equipment stability.

When the speed of the material conveying travelling crane is not changed, the time period for finishing one tea pile is also not changed, and the tea pile can be controlled only by controlling the quantity of the input tea.

Again according to the above example, A, B, C three leaves, in a ratio of 3:2:2, then a tea leaf requires three tea piles, assuming a tea leaf of type a weighs m, then the real time flow rates input are:

t is the period time for forming a longitudinal tea pile, and is also a constant because the speed of the travelling crane is constant and the length of the tea pile is constant. The flow rate S can be calculated directly and then be used for reverse thrust, and the speed of the plane conveyor 2 is controlled by combining with a belt scale, so that the laying requirement of the longitudinal tea pile can be met.

Further, in the above examples, a complete longitudinal tea pile is exemplified in the levelling bin 4, but it should be understood that the length of the tea pile is not limited, and that the length of all the tea piles is consistent, thereby ensuring that all kinds of tea leaves can be cut at each vertical cut, and no discontinuity is allowed in the middle. The invention is also advantageous in that the uninterrupted feeding and discharging of the materials are realized, thereby improving the production efficiency.

In the implementation, the speed of one input mechanism is controlled to realize the control of the whole tea blending uniformity. The method greatly saves the program memory, simplifies the programming complexity, reduces the investment and improves the working efficiency. The tea blending process is undoubtedly a great improvement.

Finally, it should be noted that although the present embodiment takes the tea blending process as an example, at present, such processes are widely applied in the processing fields of food, medicine, etc., so the application of the present invention in the related fields should also be within the protection scope.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
