Description

Tobacco plant stem pulling device

Technical Field

The application relates to the field of small-sized farm tools, in particular to a tobacco plant stem pulling device.

Background

Tobacco is an important economic crop in China, and the tax income of tobacco related industries is one of the main tax sources in China. After the tobacco leaf is picked, tobacco stems need to be pulled out by tobacco growers, so that the tobacco stems are prevented from growing again, and unnecessary soil nutrient loss is avoided; in addition, the tobacco rods can be recycled and reused as biomass energy materials, and compared with coal blocks, the tobacco rods have the advantages of quick ignition, stable combustion, convenience in operation, sanitation, easiness in storage and the like; the tobacco rod can also be used for culturing edible fungi. The tobacco stalk recovery can increase the income of tobacco growers while maintaining the sustainable development of energy products.

The tobacco stem removing is one of important steps in the tobacco stem recovery process, and due to land leveling in plain areas, the mechanized tobacco stem removing device can conveniently enter tobacco fields, and can perform batch removing work on tobacco stems, but for southwest areas where tobacco is widely planted, due to the limitation of geographical environments, the mechanized tobacco stem removing device is difficult to operate on mountainous regions, and most of the tobacco growers manually remove or dig hoes the tobacco stems in the tobacco stem removing work process, so that the tobacco stems are easily broken by the method, and physical power is consumed.

The application number is "201820079262.5" and discloses "simple and easy flue-cured tobacco rhizome extractor, including the bracing piece bottom has linked firmly the connecting plate, and connecting plate upper portion is equipped with the support, and the bottom is connected with the V type fork, inserts in the soil of tobacco trunk root with the V type fork during the use to support the support subaerial, use the support as the fulcrum, can easily extract the tobacco trunk through the bracing piece. Because the tobacco rhizome remover needs to operate the bracket when in use and the bracket also has certain requirements on the land flatness, the tobacco stem remover has complicated operation steps when in use, long time for removing the tobacco stems and inconvenient use; in addition, the V-shaped fork can only be forced by two hands when inserted into the soil, and the V-shaped fork can not reach the root of the flue-cured tobacco only by hand power at a place where the soil is hard to pull out the whole tobacco plant; in the process that the V-shaped fork pulls out the tobacco rod, the contact surface of the V-shaped fork and the soil is a plane, so that the effect of saving labor cannot be achieved.

The application number '201621323150.7' discloses a cigarette stem puller, which comprises a support rod, wherein a V-shaped clamping groove is fixedly arranged on the support rod, and the cigarette stem puller is characterized in that a sliding sleeve capable of sliding up and down along the support rod is sleeved on the support rod, a V-shaped clamping part is arranged on the sliding sleeve, and the V-shaped clamping groove and the clamping part can be mutually involuted. When the device is used, a handheld rod of an iron hoe, a spade or an iron rake is used as a supporting rod of a tobacco rod pulling device, and a positioning sleeve, a V-shaped clamping groove and a sliding sleeve are arranged on the supporting rod to carry out rod pulling operation. Although this utility model has realized using with existing equipment jointly, nevertheless can not extract the tobacco plant easily at the harder local dead man ware of soil, on the contrary pull out the tobacco plant because of the tight interlock of V-arrangement draw-in groove and clamping part is broken easily, if use instruments such as spade to loosen the soil after the work again carry out the dead man operation then increased the operating procedure that the tobacco plant was pulled out, it is inconvenient to use.

SUMMERY OF THE UTILITY MODEL
