Tobacco is an annual herb of the genus nicotiana of the family solanaceae, which includes tobacco leaves and tobacco stalks. Tobacco leaves can be collected and made into cigarettes. And the tobacco stalks are still positioned in the tobacco field after the tobacco leaves are collected. In order to enable the tobacco to be planted repeatedly in the tobacco field, the tobacco stalks need to be pulled out after the tobacco leaves are collected.
In practice, stalk plucking is typically performed manually, and operators pluck the stalks from the tobacco field by means of hoe heads and other simple labor tools. However, the tobacco stalks are pulled out manually, so that the tobacco stalks are easy to pull out, roots cannot be cleaned completely, and a large number of roots remain in the soil. Meanwhile, if the root hair carries virus, on new plants planted in the next year, diseases can appear on the new plants, and the yield and quality of tobacco are reduced.
In order to solve the defect of manual pole removal, the rotary cultivator is often used in the prior art to smash soil, so that the tobacco stalk removing effect is better. However, the rotary cultivator has better use effect in soil such as sandy soil, and in hills and mountain areas, the rotary cultivator is difficult to break the soil due to high viscosity of the soil in the hills and the mountain areas, so that root hairs are difficult to separate from the soil, and the straw pulling effect is poor.

The front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 are arranged in tandem, the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 are matched together to loosen soil of a tobacco field, refine soil and pull out tobacco stems and root hairs. The pulled tobacco stalks are finally manually collected and cleaned.
The front rotary tillage mechanism 1 in the embodiment comprises rotary tillage blades, cutter shafts, bearing seats, chain wheels and chains, wherein the rotary tillage blades are provided with a plurality of rotary tillage blades, and the rotary tillage blades are uniformly distributed around the cutter shafts as circle centers. The cutter shaft is cylindrical, and a plurality of rotary blades are arranged along the length direction of the cutter shaft in a surrounding manner. The two ends of the cutter shaft are arranged on bearing seats through bearings, and the bearing seats are fixedly arranged on the frame 5. The cutter shaft can rotate around the bearing seat, so that the rotary blade arranged on the cutter shaft rotates along with the cutter shaft. The end of the cutter shaft in the embodiment is connected with a chain wheel, and the chain wheel is in transmission connection with an output shaft of the transmission mechanism 3 through a chain.
It will be appreciated that: there are a variety of rotary tillage mechanisms in the prior art, so that the rotary tillage mechanism in the prior art can be installed at the present embodiment.
The rear rotary tillage mechanism 2 in the embodiment has the same structure as the front rotary tillage mechanism 1, but the rotary blade of the rear rotary tillage mechanism 2 is smaller than that of the front rotary tillage mechanism 1. Therefore, the front rotary tillage mechanism 1 performs a first soil loosening operation, and the rear rotary tillage mechanism 2 performs a second soil loosening operation. The rear rotary tillage mechanism 2 and the front rotary tillage mechanism 1 have different loosening and thinning degrees, so that a better loosening effect is realized.
In this embodiment, the diameter of the sprocket of the front rotary tillage mechanism 1 is larger than that of the sprocket of the rear rotary tillage mechanism 2, so that when the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 are driven to move by the transmission mechanism 3, the rotation speed of the front rotary tillage mechanism 1 is smaller than that of the rear rotary tillage mechanism 2, and the rear rotary tillage mechanism 2 can break soil more thoroughly, so that more tobacco root systems can be taken out.
In this embodiment, the transmission mechanism 3 is a double-shaft speed reducer. The front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 are respectively connected with different output shafts of the double-shaft speed reducer. The transmission 3 is connected to the output shaft of the tractor by a cardan shaft. When the tractor works, the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 can work by the driving of the double-shaft speed reducer, so that the soil loosening operation of the tobacco field is realized.
Of course, it will be appreciated that in some embodiments, two driving motors may be directly provided, and the two driving motors are respectively connected with the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 through chain transmission, so that the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 can work normally.
In order to enable the frame 5 in the embodiment to walk along with the tractor, the whole tobacco field is subjected to handle bar. In this embodiment, a connection part 51 is provided on the frame 5, and is connected to a tractor through the connection part 51.

Bolts can be installed in each connecting hole, so that the connecting holes are mutually overlapped and connected with the connecting holes of the tractor. The frame 5 also moves as the tractor walks along the tobacco field. The front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 which are arranged on the frame 5 are matched together to realize the pulling rod of the tobacco field.
In order to avoid that the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 extend into the ground too deeply in the embodiment, the embodiment comprises a depth limiting mechanism 4, and the depth limiting mechanism 4 is respectively arranged at the left side and the right side of the frame 5, so that the left side and the right side of the frame 5 are supported. The depth limiting mechanism 4 of the present embodiment includes a support plate and a support wheel. The support plate is fixedly mounted on the support and extends to the side face of the support. The supporting wheel is installed at the bottom of backup pad. When the stalk pulling machine works, the supporting wheels are positioned in the furrows of the tobacco lands and can move along the furrows. The support wheels and the support plates cooperate with each other to support the frame 5 such that the frame 5 is at a predetermined height. The front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 do not go deep into the soil.
In this embodiment, the depth limiting mechanisms 4 on two sides are detachably connected with the frame 5, and two rows of adjusting holes may be disposed on the surface of the frame 5 during implementation. The adjusting holes are arranged from top to bottom. Simultaneously, set up two mating holes at the top of backup pad. The matching hole and the adjusting hole are opposite through bolts, so that the depth limiting mechanism 4 can be detachably arranged on the frame 5.
When the limiting depth of the depth limiting mechanism 4 needs to be adjusted, the supporting plate can be installed at different positions of the adjusting hole, so that the depth limiting mechanism 4 is installed at different heights. When the depth limiting mechanism 4 is located at different heights, the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 can be supported at different height positions.
The following is a further detailed description of the embodiments: in operation, the frame 5 is fixedly connected with the tractor through the connecting portion 51. When the tractor moves, the frame 5 moves accordingly. The output shaft of the tractor is connected with the input shaft of the double-shaft speed reducer by adopting a universal joint, and the output shaft of the tractor rotates to drive the double-shaft speed reducer to work. The double-shaft speed reducer works to drive rotary blades of the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 to rotate, so as to loosen soil of a tobacco field, refine soil and pull out tobacco stalks and root hairs. The tobacco stalks are manually collected and cleaned.
Meanwhile, when the tractor drives the frame 5 to move, the supporting wheels of the depth limiting mechanism 4 walk in furrows of a tobacco field to support the stalk pulling machine, so that the front rotary tillage mechanism 1 and the rear rotary tillage mechanism 2 are prevented from being too deep.
