[0002] Tobacco is an annual herbaceous plant of the genus Nicotiana in the Solanaceae family. It has a thick root, a stem height of 0.7 to 2 meters, and a slightly lignified base. The tobacco leaves are harvested when the leaf surface changes from green to yellow-green, and the straw is cleared out of the tobacco field after harvesting. Among them, northern tobacco is mainly planted in ridges, and is mainly planted individually. Due to the limitations of this terrain and scale, it is difficult to use medium and large comprehensive machinery to complete straw cleaning. Therefore, at present, straw cleaning is first done by a small machine such as a tractor-driven planing mechanism to dig the straw out of the soil, and then the straw is picked up manually and put on the field transport vehicle to transport the straw out of the tobacco field. This straw collection method has a large amount of manual labor and occupancy, and the soil in the tobacco field is often humid, which will cause more inconvenience to manual travel and picking, resulting in high overall labor intensity of straw collection operations, but extremely low efficiency.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, exemplary embodiments of the present invention are described only by way of illustration. It is undoubted that one of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0025] like Figures 1 to 6As shown, the tobacco field straw collector includes a frame 1. The frame 1 serves as a carrier of other functional structures, and its structure can be flexibly arranged according to actual needs. This is also easily obtained by those skilled in the art in combination with conventional technical means, and will not be repeated here. It also includes rake teeth 2, a height control mechanism 3 and a soil beating device 4. The rake teeth 2 are fixedly arranged at the rear end of the frame 1, and the rake teeth 2 are arranged in the left and right directions. The lower ends of the rake teeth 2 can be inserted into the soil. The rake teeth 2 can rake the straw on the soil surface as the frame 1 moves forward. It should be noted that the "front", "rear", "left" and "right" involved in this embodiment are all defined to adapt to the front, rear, left and right directions when moving, so as to adapt to conventional cognition and make the description clearer, and are not intended to limit the scope of protection.

[0026] Furthermore, if Figure 3 and Figure 4 As shown, the height control mechanism 3 is fixedly arranged at the front end of the frame 1, and the height control mechanism 3 is used to control the depth of the rake teeth 2 inserted into the soil, so that the depth of the rake teeth 2 inserted into the soil can rake the straw without causing obvious obstruction to the movement. The soil beating device 4 is fixedly arranged on the frame 1, and the soil beating device 4 is located on the front side of the rake teeth 2, and the soil beating device 4 is used to beat the straw.

[0027] Among them, the height control mechanism 3 includes a traction connecting rod 31 and an adjustable connecting rod 32. The traction connecting rod 31 and the adjustable connecting rod 32 are both hinged to the front end of the frame 1. The adjustable connecting rod 32 is adjustable in length. Under the restriction of the traction connecting rod 31, the end of the frame 1 away from the adjustable connecting rod 32 will produce a height change, thereby adjusting the height of the rake teeth 2. After the length of the adjustable connecting rod 32 is fixed, the height of the rake teeth 2 is also fixed.

[0028] Furthermore, the adjustable connecting rod 32 includes a connecting rod head 33 and a connecting tube 34. Two connecting rod heads 33 are provided. Both ends of the connecting tube 34 are respectively threadedly connected to the two connecting rod heads 33. One end of one connecting rod head 33 away from the connecting tube 34 is hinged to the front end of the frame 1, and the other end of the other connecting rod head 33 away from the connecting tube 34 is hinged to the tractor.

[0029] Furthermore, an adjusting external thread 331 is provided on the rod body of the connecting rod head 33, and adjusting internal threads 341 matching the adjusting external thread 331 are provided on both ends of the connecting tube 34. The spiral directions of the adjusting external threads 331 on the two connecting rod heads 33 are opposite. By rotating the connecting tube 34 and guiding with opposite spiral directions, the two connecting rod heads 33 can synchronously move closer to or farther from each other, and the total length of the adjustable connecting rod 32 can be adjusted to shorten or lengthen accordingly.

[0030] Furthermore, a fixed-length nut 35 is provided on the adjustable connecting rod 32, and two fixed-length nuts 35 are provided. Each fixed-length nut 35 is threadedly connected to an adjusting external thread 331 on a connecting rod head 33, and the two fixed-length nuts 35 are respectively located at both ends of the connecting tube 34. After the length of the adjustable connecting rod 32 is adjusted through the connecting tube 34, the fixed-length nut 35 is rotated to the corresponding end position of the connecting tube 34, and the threaded connection can be locked, thereby fixing the length of the adjustable connecting rod 32.

[0031] Furthermore, at least two traction connecting rods 31 are provided, and at least one adjustable connecting rod 32 is provided. In the present embodiment, one adjustable connecting rod 32 and two traction connecting rods 31 form a triangle shape, one adjustable connecting rod 32 is located at the top angle of the triangle, and two traction connecting rods 31 are located at the bottom angle of the triangle. In actual application, the traction connecting rod 31 can also directly adopt the existing connecting rod on the traction frame on the rear side of the tractor, that is, when designing the present embodiment, its front end hinged ear plate is designed to adapt to the rear traction mechanism of the existing tractor, so as to facilitate the matching use.

[0032] The soil-breaking device 4 includes a soil-breaking shaft 42 , a soil-breaking rod 43 and a soil-breaking driver 46 . The soil-breaking shaft 42 is movably disposed at the bottom end of the frame 1 , and the soil-breaking shaft 42 is disposed transversely.

[0033] Furthermore, a radially arranged soil-beating rod 43 is provided on the outer peripheral surface of the soil-beating shaft 42. The soil-beating rod 43 is a direct acting structure for beating the straw, and its shape can be set according to needs. Since its shape is not necessarily a regular straight rod, its radial setting on the soil-beating shaft 42 should be understood as being roughly in a radial direction. The soil-beating shaft 42 is transmission-connected to a soil-beating driver 46, and the soil-beating driver 46 drives the soil-beating shaft 42 to rotate at a high speed, thereby achieving strong beating of the straw and shaking off the wet soil.

[0034] Further, the beating device 4 is arranged to beat the straw backwards, so that when the straw passes through the beating device 4, the beating of the beating device 4 can be driven to the rake teeth 2, thereby promoting the rapid collection of the straw. For this embodiment, when the beating rod 43 is at the lower part of the beating shaft 42, it should rotate backwards to achieve backward beating.

[0035] Among them, the soil-beating driver 46 includes a transmission box 44 and a universal coupling 45. The transmission box 44 is fixedly arranged on the frame 1, and the transmission box 44 is located above the soil-beating shaft 42. The soil-beating shaft 42 is connected to the output shaft of the transmission box 44 by transmission. The input shaft of the transmission box 44 is connected with the universal coupling 45, that is, this embodiment also directly adopts the power take-off shaft at the rear of the tractor to realize power drive, and conventional gears, worm gears, etc. can be used in the transmission box 44 to realize power transmission. This is easy for technical personnel in this field to obtain, and it will not be repeated here and is not marked in the figure.

[0036] Furthermore, if Figure 4 As shown, a ground clearance 41 for straw to pass through is provided between the soil beating device 4 and the soil surface. The purpose of providing the ground clearance 41 in this embodiment is to enable the straw to be smoothly raked by the rake teeth 2. However, due to the uneven ground of the tobacco field and the unstable posture of the straw after raking, the straw will always be tilted or partially extended to the soil beating device 4 after being raked, and then be strongly beaten by the soil beating device 4. The strong beating can directly or indirectly act on the raked straw, so that the wet soil at the root of the straw is shaken off, thereby reducing the weight of the raking and reducing the travel resistance. In this embodiment, in combination with the ground conditions after the straw is dug out, the randomness of the straw posture and the mechanism of raking the straw, the soil beating device 4 with the ground clearance 41 is adopted, which can simultaneously achieve the effects of not affecting the smooth raking, not causing obvious hindrance to the travel, and being able to shake off most of the wet soil.

[0037] Furthermore, a reinforcing cross bar 21 is fixedly arranged between the rake teeth 2, and the reinforcing cross bar 21 can improve the anti-deformation ability of the rake teeth 2 and ensure reliable raking.

[0038] When in use, the traction connecting rod 31 and the adjustable connecting rod 32 are hinged on the rear side of the tractor, and then the length of the adjustable connecting rod 32 is adjusted by rotating the connecting tube 34, thereby adjusting the height of the rake teeth 2. When the frame 1 is pulled by the tractor, the rake teeth 2 can form a raking effect on the straw, and the power take-off shaft at the rear of the tractor drives the beating shaft 42 to rotate through the universal coupling 45 and the transmission box 44, thereby driving the beating rod 43 to rotate, so as to beat the straw.

[0039] Based on the ground conditions after the straw is raked out, the randomness of the straw posture and the collection mechanism of rake, the utility model adopts a soil beating device with a distance from the ground, so that while not affecting the smooth rake, the soil is not lifted, and there is no obvious hindrance to the movement, and most of the wet soil on the straw can be shaken off, reducing the weight of the rake. In addition, the length of the adjustable connecting rod can be adjusted by rotating the connecting tube, so as to achieve the purpose of adjusting the height of the rake teeth. Finally, the straw arrives at the end of the tobacco field with the traction chassis under the rake of the rake teeth, and the straw is quickly collected, which greatly simplifies the collection operation of manually entering the tobacco field to pick up the straw, and has a favorable effect on reducing the labor intensity of straw collection and improving the efficiency of straw collection. The present embodiment is small in size and can be installed and used on a tractor, so it is very flexible in traveling and turning around in the tobacco field, and is suitable for use in ridges and small-scale planting.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
