Flue-cured tobacco stem pulling machine

Abstract

The invention relates to a flue-cured tobacco stem pulling machine, which belongs to the technical field of machinery and solves the technical problems of unreasonable design and the like of the prior art. The stem pulling machine comprises a suspension machine frame, depth wheels and a break shovel, wherein the depth wheels and the break shovel are arranged on the lower portion of the suspension machine frame; drive sprockets, jockey sprockets, a clamping chain and a clamping pressing plate are arranged on the suspension machine frame; the ring-shaped clamping chain is sleeved between the drive sprockets and the jockey sprockets and respectively meshed with the drive sprockets and the jockey sprockets; the drive sprockets are connected with a motive power mechanism and driven to rotate by the motive power mechanism; the clamping pressing plate is positioned on one side of the clamping chain; a clamping channel for enabling tobacco stems to enter and be pulled up and outputted is formed between the clamping pressing plate and the clamping chain; one end of the clamping channel is a tobacco stem inlet positioned behind the break shovel, and the other end of the clamping channel is a tobacco stem outlet. The flue-cured tobacco stem pulling machine has the advantages that: 1 the break shovel loosens soil at the root portions of the tobacco stems, thereby being extremely labor-saving in pulling the stems. 2 the root portions carry a small amount of soil, thereby being favorable for cleaning the tobacco stems. 3 a lead-in port enables the tobacco stems to be smoothly conveyed into the clamping channel.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to agricultural farming equipment, in particular to a flue-cured tobacco rod pulling machine. Background technique [0002] In the process of tobacco planting, after the tobacco leaves are picked, the tobacco rods left in the field are not only difficult to rot, but also usually carry tobacco pathogenic bacteria, so they must be cleaned up as much as possible to facilitate subsequent cultivation and realize the smoothness of tobacco leaf production. sustainable development. At present, the extraction of tobacco stems is mainly carried out manually. However, due to the well-developed root system of tobacco, manual extraction requires a lot of labor and time. It is only suitable for small fields, and it is impossible to complete large-scale fields. [0003] For this reason, people have carried out long-term exploration, have proposed various mechanical type cleaning devices. Mechanic...

Problems solved by technology

However, the excavation pocket rotor in the above scheme realizes excavation through the intermittent operation of the spikes into the soil. This structure has technical defects such as poor digging ability, shallow penetration of the spikes, and laborious spikes.

In addition, because the tooth nails are distributed in gaps, it is easy to cause leakage

On the other hand, the overall structure is complicated, the manufacturing cost is high, and it will still be affected by the lodging of the tobacco rod
