Description

Technical Field

[0001] This utility model relates to the field of tobacco re-drying technology, and in particular to an automatic collection device for scattered tobacco leaves at the outlet end of a tobacco re-drying machine. Background Technology

[0002] Currently, tobacco leaf re-drying machines are mainly used for re-drying tobacco leaves after threshing. The conveyor belt structure it employs, based on the principle of polygonal sprocket operation, creates a gap between the conveyor belt and the equipment's mesh cleaning device when the belt is at its maximum operating wheelbase. This results in some leaves not being thoroughly cleaned and scattering. Existing scattered tobacco leaf collection devices are inverted trapezoidal troughs, located below the end of the conveyor belt and arranged along its width. The sides of the collection device are sloped, and the scattered tobacco leaves fall slowly due to their own weight, causing them to accumulate on the sides of the collection device for extended periods. Given the high temperature and humidity environment, this significantly impacts the tobacco leaves, easily causing secondary contamination. Furthermore, the tobacco leaves in the collection device are manually removed, which is time-consuming and labor-intensive. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an automatic collection device for scattered tobacco leaves at the outlet end of a tobacco re-drying machine, so as to solve the technical problems mentioned in the background art.

[0004] The objective of this utility model is achieved through the following technical solution: An automatic collection device for scattered tobacco leaves at the outlet of a tobacco re-drying machine includes an inverted trapezoidal trough. The inverted trapezoidal trough is located below the end of the conveyor belt of the tobacco re-drying machine and is arranged along the width direction of the conveyor belt. Compressed air jetting device and tobacco leaf collection box are respectively provided at both ends of the inverted trapezoidal trough. The jetting direction of the compressed air jetting device is towards the tobacco leaf collection box. The compressed air jetting device includes multiple nozzles, which are arranged at intervals along the width direction of the inverted trapezoidal trough. The two outermost nozzles are circular nozzles and are respectively located close to the two sides of the inverted trapezoidal trough. The remaining nozzles are conical nozzles. The multiple nozzles are connected to a compressed air supply system.

[0005] Furthermore, multiple nozzles are mounted on a mounting block, which is installed in the lower middle part of an inverted trapezoidal groove.

[0006] Furthermore, the mounting block is provided with a cavity, which is connected to a compressed air supply system, and multiple nozzles are respectively connected to the cavity.

[0007] Furthermore, the tobacco collection box is equipped with a barrier, which opens to one side of the inverted trapezoidal groove.

[0008] The beneficial effects of this utility model are: The automatic collection device for scattered tobacco leaves at the outlet of the tobacco re-drying machine proposed in this utility model has two outermost circular nozzles used to blow tobacco leaves off the two sides of the inverted trapezoidal groove, and the remaining conical nozzles used to blow tobacco leaves out of the bottom of the inverted trapezoidal groove. The tobacco leaf collection box collects the blown tobacco leaves. This device can quickly and automatically collect scattered tobacco leaves from the tobacco re-drying machine.

[0009] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0014] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0015] Example 1 like Figure 1The automatic collection device for scattered tobacco leaves at the outlet of the tobacco re-drying machine shown includes an inverted trapezoidal trough 1, which is made of stainless steel. The inverted trapezoidal trough 1 is located below the end of the conveyor belt 2 of the tobacco re-drying machine and is arranged along the width of the conveyor belt 2. Compressed air jetting device and tobacco leaf collection box 3 are respectively provided at both ends of the inverted trapezoidal trough 1. The jetting direction of the compressed air jetting device is towards the tobacco leaf collection box 3. The compressed air jetting device includes multiple nozzles, which are spaced apart along the width of the inverted trapezoidal groove 1. The outermost nozzles are circular nozzles 4, which are positioned close to the two sides of the inverted trapezoidal groove 1. The remaining nozzles are conical nozzles 5. The nozzles are mounted on a mounting block 6, which is connected at both ends to the two sides of the inverted trapezoidal groove 1. The mounting block 6 is located in the lower middle part of the inverted trapezoidal groove 1 and has a cavity. The cavity is connected to a compressed air supply system (not shown in the figure).
