A tobacco bundle in-line spraying device

Abstract

This invention provides a tobacco bundle spraying device that effectively solves the problem that existing spraying devices cannot spray inside tobacco bundles. The solution includes a water inlet pipe, closed at the right end, with a water outlet in the middle. A sliding cylinder is fitted onto the water inlet pipe, consisting of a left and right cylinder with a gap between them. The left and right cylinders are fixed together by a connecting rod. A rotatable annular shell is installed at the gap between the left and right cylinders, and multiple nozzles are installed around the annular shell. Multiple arc-shaped elastic rods connect the left end of the sliding cylinder to the right end of the water inlet pipe, forming a cage-like structure. An annular protrusion is fixed to the left end of the water inlet pipe, and a compression spring is installed between the left ends of the sliding cylinders. This invention has an ingenious structure, enabling spraying inside tobacco bundles. After insertion into the tobacco bundle, it maximizes internal spraying while minimizing the concentration of exogenous enzymes.

Description

Technical Field

[0001] This utility model relates to the field of tobacco production process research, and in particular to a tobacco bundle spraying device. Background Technology

[0002] In tobacco production, exogenous enzyme preparations are sprayed onto the surface of tobacco leaves. Existing processes use small sprayers to spray the tobacco leaf bundles, such as the pesticide real-time mixing spray tank disclosed in patent document CN109497022A and the sprayer and waterer disclosed in CN102907299A. These can only spray the surface, and even if the nozzle is inserted into the tobacco leaf bundle, the spray cannot be spread.

[0003] To address the aforementioned problems, a tobacco bundle spraying device is provided. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a tobacco bundle spraying device, which effectively solves the problem that the existing spraying devices cannot perform spraying operations inside the tobacco bundle.

[0005] The technical solution includes an inlet pipe, which is closed at the right end and has a water outlet in the middle. A slide cylinder is fitted onto the inlet pipe, which is divided into a left cylinder and a right cylinder with a gap between them. The left and right cylinders are fixed together by a connecting rod. A rotatable annular shell is installed at the gap between the left and right cylinders, and multiple nozzles are installed around the annular shell. Multiple arc-shaped elastic rods are connected between the left end of the slide cylinder and the right end of the inlet pipe to form a cage structure. An annular protrusion is fixed at the left end of the inlet pipe, and a compression spring is installed between the left ends of the slide cylinders.

[0006] Furthermore, the right end of the water inlet pipe is tapered.

[0007] Furthermore, the axis of the nozzle is tangent to the annular shell.

[0008] This invention has a clever structure that allows for spraying inside the tobacco bundle. After the tobacco bundle is inserted, it can spray as much as possible inside, minimizing the excessive concentration of exogenous enzyme preparations. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 6 The present invention includes a water inlet pipe 1, which is closed at the right end. A water outlet 2 is provided in the middle of the water inlet pipe 1. A slide cylinder is fitted on the water inlet pipe 1. The slide cylinder is divided into two parts: a left cylinder 3 and a right cylinder 4. There is a gap between the left cylinder 3 and the right cylinder 4. The left cylinder 3 and the right cylinder 4 are fixed together by a connecting rod 5. A rotatable annular shell 6 is installed at the gap between the left cylinder 3 and the right cylinder 4. Multiple nozzles 7 are installed around the annular shell 6. Multiple arc-shaped elastic rods 8 are connected between the left end of the slide cylinder and the right end of the water inlet pipe 1 to form a cage structure. An annular protrusion is fixed at the left end of the water inlet pipe 1. A compression spring 9 is installed between the left ends of the slide cylinders.

[0017] To facilitate insertion into the tobacco bundle, the right end of the water inlet pipe 1 is tapered.

[0018] In order to spray the spray evenly around the inside of the bundle, the axis of the nozzle 7 is tangent to the annular shell 6.

[0019] It is worth noting that during the spraying process, since the center of the nozzle 7 is tangent to the annular shell 6, the reaction force caused by the high-pressure water causes the annular shell 6 to rotate, and the rotation allows for uniform spraying around the perimeter.

[0020] In the initial state, the compression spring 9 pushes the slide cylinder to the right, and the right end of the slide cylinder abuts against the right end of the water inlet pipe 1. At this time, the annular shell 6 is exactly at the water outlet 2, and the nozzle 7 sprays outward. When the slide cylinder moves to the left, the right cylinder 4 in the slide cylinder can block the water outlet 2, and the nozzle 7 does not work.

[0021] When it is necessary to spray the inside of the tobacco bundle, such as Figure 6 As shown, hold the device in one hand and pull the slide cylinder to the left. At this time, the elastic bar's arc narrows to the left, making it easier to insert into the bundle. Nozzle 7 does not spray water at this time. After insertion, release the slide cylinder. Under the action of the compression spring 9 and the elastic rod 8, the slide cylinder returns to its original shape to the right. The elastic rod 8 returns to its original arc. Figure 1 As shown, this also expands the inside of the tobacco bundle. During the spraying process of nozzle 7, the annular shell 6 also rotates under the reaction force, so that the tobacco leaves around this area can be sprayed as evenly as possible.

[0022] This solution is specifically designed for spraying inside the tobacco bundle. When inserted into the tobacco bundle, you can let go and the nozzle 7 will spray inside the tobacco bundle. After detaching from the tobacco bundle, you should pinch the water inlet pipe 1 and the left end of the slide tube to seal the water outlet 2 with the right tube 4 in the slide tube, thus preventing waste.

[0023] This invention has a clever structure that allows for spraying inside the tobacco bundle. After the tobacco bundle is inserted, it can spray as much as possible inside, minimizing the excessive concentration of exogenous enzyme preparations.
