Description

Technical Field

[0001] This utility model belongs to the field of flue-cured tobacco planting machinery technology, specifically relating to a flue-cured tobacco folding three-row stalk pulling machine. Background Technology

[0002] Tobacco production is a labor-intensive industry with numerous production processes and a large and concentrated workforce, leading to labor shortages and continuously rising costs in key production stages. The application of agricultural machinery in the stalk pulling stage is low, and it is impossible to pull out waste tobacco stalks and stubble at the same time. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a folding three-row tobacco stalk puller that enables simultaneous stalk pulling across three rows, significantly improving stalk pulling efficiency. The process is completed in one operation, simultaneously removing waste tobacco stalks and stubble, reducing the number of operations. The rapid and effective removal of tobacco stalks cuts off the soil, continuously providing nutrients to the waste stalks and ensuring soil fertility.

[0004] The technical solution adopted by this utility model is:

[0005] A flue-cured tobacco folding three-row stalk puller includes a traction frame, a main frame, a gear transmission box, a transmission mechanism, two auxiliary frames, two hydraulic telescopic components, and three stalk puller blade assemblies. The traction frame is mounted on the main frame, and the auxiliary frames are rotatably connected to the left and right ends of the main frame. A hydraulic telescopic component connects the main frame and the auxiliary frames, enabling the auxiliary frames to fold downwards and operate horizontally. Stalk puller blade assemblies are mounted on the main frame and the gear transmission box. The front input end of the gear transmission box is connected to the tractor's power system, and the left and right output ends of the gear transmission box drive the three stalk puller blade assemblies to rotate through the transmission mechanism.

[0006] Compared with the prior art, the present invention has the following advantages:

[0007] 1. This utility model is used in the stalk pulling process of flue-cured tobacco production, which can realize simultaneous operation of three rows, greatly improving the stalk pulling efficiency. The stalk pulling machine can operate on about 90 acres per day, which is 3 times more efficient than the traditional single-row stalk pulling operation. It effectively solves the "bottleneck" problem in the stalk pulling process of tobacco production and fully meets the needs of existing flue-cured tobacco planting.

[0008] 2. This utility model equips the three-row stalk pulling module with a drive shaft, and uses the power of an agricultural tractor to carry out the operation. The drive shaft drives three sets of blades to efficiently cut the tobacco plant roots in the soil. The stalk pulling operation is completed in one go, and the tobacco stalks and stubble in the field are pulled out at the same time, reducing the number of stalk pulling operations. At the same time, pulling out the tobacco stalks can effectively cut the soil to continuously provide nutrients for the discarded tobacco stalks and ensure soil fertility.

[0009] 3. This utility model is equipped with a hydraulic device, which can be folded when not in use, saving storage space. Attached Figure Description

[0014] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model will be provided below with reference to the accompanying drawings.

[0015] like Figure 1 , Figure 2 As shown, this utility model provides a folding three-row tobacco stalk puller, including a traction frame 1, a main frame 2, a gear transmission box 3, a transmission mechanism 8, two auxiliary frames 6, two hydraulic telescopic components 7, and three stalk puller blade groups 5. The traction frame 1 is installed on the main frame 2 for connection to a tractor. The auxiliary frames 6 are rotatably connected to the left and right ends of the main frame 2, and the hydraulic telescopic components 7 are connected between the main frame 2 and the auxiliary frames 6. The hydraulic telescopic components 7 can drive the auxiliary frames 6 to fold downwards and operate horizontally. The stalk puller blade groups 5 are installed on the main frame 2 and the two auxiliary frames 6. The gear transmission box 3 is installed on the main frame 2. The front input end of the gear transmission box 3 is connected to the power system of the tractor, and the left and right output ends of the gear transmission box 3 drive the three stalk puller blade groups 5 to rotate through the transmission mechanism 8.

[0016] The lever-pulling knife assembly 5 includes a main shaft 501, multiple connecting plates 502, and multiple lever-pulling knives 503; the multiple connecting plates 502 are all annular plates and are fixedly mounted on the main shaft 501, and the multiple lever-pulling knives 503 are evenly distributed in annular shape on the outside of the connecting plates 502, and each lever-pulling knife 503 is connected to the multiple connecting plates 502 by bolts.

[0017] like Figure 3As shown, each of the lever cutters 503 includes a blade sleeve 504, a connecting rod 506, and multiple blades 505; the multiple blades 505 can be inserted side by side into the blade sleeve 504 and are connected and fixed to the blade sleeve 504 in series by the connecting rod 506. The two ends of the connecting rod 506 protrude from the blade sleeve 504 and are fixed to the blade sleeve 504 by nuts.

[0018] The transmission mechanism 8 includes four chain drive boxes 801, two chain drive boxes 803, and four universal drive shafts 802. Two chain drive boxes 801 are provided on each of the left and right output ends of the gear transmission box 3, and the chain drive boxes 801 are sequentially connected to each other through the universal drive shafts 802. The lower ends of the two chain drive boxes 801 in the middle are connected to the main shaft 501 of the lever knife assembly 5 in the middle. The chain drive boxes 801 on both sides are connected to one end of the main shaft 501 of the lever knife assembly 5 on both sides, and the other end of the main shaft 501 of the lever knife assembly 5 on both sides is connected to the chain drive box 803. The four chain drive boxes 801 and the two chain drive boxes 803 are fixedly connected to the corresponding main frame 2 or sub-frame 6.

[0019] The gear transmission box 3 transmits power to the chain transmission box 801, which in turn transmits power to the main shaft 501 of the rod-pulling knife assembly 5, thereby driving the rod-pulling knife 503 to rotate and realize the rod-pulling operation.

[0020] The hydraulic telescopic assembly 7 includes a hydraulic telescopic cylinder 701, two hinge shafts 702, and two axle seats 703. The two axle seats 703 are respectively fixed to the main frame 2 and the sub-frame 6. Both ends of the hydraulic telescopic cylinder 701 are hinged to the axle seats 703 via the hinge shafts 702. The hydraulic telescopic cylinder 701 is connected to the tractor's hydraulic system and is powered by the tractor's hydraulic system. The extension and retraction of the hydraulic telescopic cylinder 701 can cause the sub-frame 6 to fold upwards and unfold downwards.

[0021] Each of the sub-frames 6 is detachably equipped with a U-shaped bracket 4. A connecting cylinder is inserted into each of the two upper ends of the U-shaped bracket 4 and fixed by a pin, and the connecting cylinder is fixed to the sub-frame 6.

[0022] During operation, the agricultural tractor provides power, which drives the three stalk-pulling blade assembly 5 through the transmission mechanism 8. It can efficiently cut the tobacco plant roots in the soil and pull out the waste tobacco stalks and stubble in one go. It is also equipped with a hydraulic telescopic component 7, which can be folded up by itself, saving storage space while ensuring the flexibility and adaptability of the machine in different storage sites.

[0023] This rod puller can be used in flue-cured tobacco planting areas across the country, as well as in flat and gentle slope terrain.
