The driving member 22 is connected to the vehicle frame 11 and is hinged to both harvesting members, so that the two harvesting shears 21 are opened or closed at the same time and cut the vegetation stems.

[0062] Compared with the prior art, a harvesting shear 21 is set at a position above the top plane of the vehicle frame 11 to cut and harvest the vegetation stems, and another harvesting shear 21 is set at a position below the bottom plane of the vehicle frame 11 to cut the portion of the vegetation stems that is higher than the bottom plane of the vehicle frame 11, so as to avoid the portion of the vegetation stems that is higher than the bottom plane of the vehicle frame 11 blocking the travel path of the cart and hindering the normal movement of the cart, making it convenient for the cart to move in the field. It can solve the problem in the prior art that the stems remaining in the soil after being cut are higher than the bottom of the cart, blocking the travel path of the cart and hindering the normal movement of the cart, thus causing inconvenience in use.

[0063] In this embodiment, Figure 3 、 Figure 4 As shown, a collecting tank 12 is formed inside the vehicle body frame 11. The cross-section of the collecting tank 12 is an isosceles trapezoid, and the cross-sectional area of ​​the collecting tank 12 gradually increases toward the top of the vehicle body frame 11.

[0066] Among them, the two first cross beams 111 are parallel to each other and arranged at intervals, the two ends of the two first vertical beams 112 are respectively connected to the two ends of the two first cross beams 111, the second cross beam 113 is arranged parallel to the first cross beam 111 below the first cross beam 111, and the two second cross beams 113 are parallel to each other and arranged at intervals, the two ends of the two second vertical beams 114 are respectively connected to the middle parts of the two second cross beams 113, and the four first connecting beams 115 are distributed in pairs on both sides of the two second cross beams 113, and are respectively connected to the two first cross beams 111 and the second cross beams 113 located on the same side.

[0067] The two first transverse beams 111 , the two first vertical beams 112 , the two second transverse beams 113 , the two second vertical beams 114 and the four first connecting beams 115 form a hollow collecting trough 12 structure, and the collecting trough 12 has a gradually enlarged opening end to facilitate the collection of materials.

[0068] In one embodiment, see Figure 3 、 Figure 4 The first reinforcing beam 116 and the second cross beam 113 are spaced apart, and the two first reinforcing beams 116 are parallel to each other and spaced apart. The second reinforcing beam 117 and the second vertical beam 114 are spaced apart, and the two second reinforcing beams 117 are parallel to each other and spaced apart. The two ends of the two second connecting beams 118 are respectively connected to the first reinforcing beam 116, the second reinforcing beam 117, the first cross beam 111 and the first vertical beam 112.

[0069] The vehicle frame 11 further includes two first reinforcing beams 116 , two second reinforcing beams 117 and four second connecting beams 118 , which are interconnected to form a hollow reinforcing structure for improving the stability of the vehicle frame and increasing the load-bearing capacity of the device.

[0070] Furthermore, the first cross beam 111, the two first vertical beams 112, the two second cross beams 113, the two second vertical beams 114 and the four first connecting beams 115, the two first reinforcing beams 116, the two second reinforcing beams 117 and the four second connecting beams 118 are all aluminum alloy profiles that are common and easy to purchase on the market, and are formed into a hollow bracket structure by welding. This is a conventional setting known to those skilled in the art and will not be elaborated on.

[0071] In this embodiment, the trolley 1 also includes a screen 13, two wheels 14, two handrails 15 and two support rods 16. The screen 13 spans the two second vertical beams 114 and the two second reinforcing beams 117, and is connected to the two second vertical beams 114 and the two second reinforcing beams 117. The wheels 14 are arranged in a one-to-one correspondence with the second cross beams 113, and the two wheels 14 are respectively rotatably connected to the second cross beams 113. The handrails 15 are parallel to each other and spaced apart, and are both connected to a first vertical beam 112. The two support rods 16 are parallel to each other and spaced apart, and one end of the two support rods 16 is respectively connected to a second reinforcing beam 117, and the other end is in contact with the ground.

[0072] By providing independently rotatable wheels 14 on both sides of the frame, it is convenient for the user to push the entire device. Electric drive can also be achieved by a motor, which will not be described in detail here.

[0073] Furthermore, the two handrails 15 and the two support rods 16 are respectively used to facilitate the user to push or stabilize the trolley 1. A screen 13 is also provided at the bottom of the collecting trough 12, which can prevent the stemmed tobacco leaves from falling out while reducing the weight. At the same time, when the trolley 1 is pushed forward, the cut stemmed tobacco leaves fall into the collecting trough 12, which can screen some impurities and reduce the weight of the material in the collecting trough 12.

[0074] In this embodiment, Figure 5As shown, the harvesting shears 21 include a first handle 211, a second handle 212, a first blade head 213 and a second blade head 214. One end of the first handle 211 is fixedly connected to the middle part of the other first vertical beam 112, and the middle part of the second handle 212 is hinged to the middle part of the first handle 211. The first blade head 213 is detachably connected to one end of the second handle 212. The second blade head 214 is arranged relative to the first blade head 213 and is detachably connected to the other end of the first handle 211. The driving member 22 is hinged to the other end of the second handle 212, and is used to drive the first handle 211 and the second handle 212 to rotate around their hinges as axes, and to make the first blade head 213 and the second blade head 214 rotate closer to or away from each other.

[0075] The harvesting shears 21 are composed of a first handle 211, a second handle 212, a first blade head 213 and a second blade head 214, which are hinged to each other. By driving the first handle 211 and the second handle 212 to rotate relative to each other, the first blade head 213 and the second blade head 214 can be rotated closer to or away from each other, thereby shearing the material placed between the first blade head 213 and the second blade head 214.

[0076] Specifically, in this device, one end of the second handle 212 is hinged to the middle of the first handle 211, and the first handle 211, the second handle 212, and the second blade head 214 are hinged to each other. The rotation of the first handle 211 and the second handle 212 around their hinge can drive the first blade head 213 and the second blade head 214 to rotate closer to or away from each other.

[0077] Furthermore, the first cutting head 213 and the second cutting head 214 are detachably connected to the first handle 211 and the second handle 212 , respectively, so that the user can conveniently inspect or replace the first cutting head 213 and the second cutting head 214 .

[0078] In one embodiment, see Figure 1 、 Figure 5 The harvesting assembly 2 also includes two guide rods 23, which are respectively arranged along the extension direction of the other end of the first handle 211 and one end of the second handle 212, and are respectively connected to the other end of the first handle 211 and one end of the second handle 212.

[0079] By arranging two guide rods 23 along the extension direction of the other end of the first handle 211 and one end of the second handle 212 respectively, the tobacco stems can be better guided into between the first blade head 213 and the second blade head 214, which is convenient for user operation and improves cutting efficiency.

[0080] Furthermore, the two guide rods 23 are respectively welded to the blade backs of the first cutting head 213 and the second cutting head 214 .

[0081] In one embodiment, see Figure 5 The second cutting head 214 is further formed with a plurality of sawtooth grooves 215 relative to the first cutting head 213 , and the plurality of sawtooth grooves 215 are evenly arranged along the length direction of the second cutting head 214 .

[0082] After the first cutting head 213 and the second cutting head 214 are close to each other, the first cutting head 213 can be embedded in the second cutting head 214 to improve the shearing efficiency.

[0083] Furthermore, the second cutting head 214 is formed with a plurality of sawtooth grooves 215 for extending the service life of the second cutting head 214 and improving the shearing efficiency.

[0084] In this embodiment, the driving member 22 includes two steel wire ropes 221, a pull rod 222, a blocking rod 223 and an elastic part 224. The steel wire ropes 221 are arranged in a one-to-one correspondence with the second handle 212, and one end of the steel wire rope 221 is hinged to the other end of the second handle 212. One end of the pull rod 222 is rotatably connected to a second connecting beam 118, and the other end can rotate relative to a second connecting beam 118. The other ends of the two steel wire ropes 221 are both connected to the middle of the pull rod 222. The blocking rod 223 is arranged on the rotation path of the other end of the pull rod 222 and is connected to a first crossbeam 111. One end of the elastic part 224 is connected to the other end of the first handle 211, and the other end is connected to the other end of the second handle 212, which is used to drive the first handle 211 and the second handle 212 to rotate and reset respectively.

[0085] By rotating the pull rod 222 relative to the vehicle frame 11, the relative lengths of the two steel ropes 221 can be changed simultaneously, thereby simultaneously driving the two second handles 212 to rotate relative to the two first handles 211, respectively, so that the harvesting shears 21 are opened or closed.

[0086] Furthermore, the elastic portion 224 here is a spring that is common and easy to purchase on the market, and can also be a tension spring. The elastic portion 224 here belongs to a conventional setting well known to those skilled in the art and will not be described in detail.

[0087] In one embodiment, see Figures 1 to 3 The driving member 22 also includes a mounting beam 225, two first guide wheels 226 and two second guide wheels 227. The mounting beam 225 is arranged between the first cross beam 111 and the first reinforcement beam 116, and is connected to the first cross beam 111 and the first reinforcement beam 116. The two first guide wheels 226 are arranged opposite to each other and are both connected to the mounting beam 225. The two second guide wheels 227 are arranged back to back and are respectively connected to the first cross beam 111 and the first reinforcement beam 116. The first guide wheel 226 and the second guide wheel 227 form a group of guide members, and the wire rope 221 passes through the first guide wheel 226 and the second guide wheel 227 in the same group.

[0088] The frame body is also provided with a guide wheel, and a steel wire rope 221 is connected to the vehicle frame 11 through the first guide wheel 226 and the second guide respectively, to realize the transmission and steering of motion, and ensure that the steel wire rope 221 can effectively drive the two second handles 212 to rotate relative to the two first handles 211, thereby improving the stability of the device.

[0089] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0090] Two harvesting shears 21 are provided on the vehicle frame 11, wherein the plane of one harvesting shear 21 is higher than the top plane of the vehicle frame 11, and the plane of the other harvesting shear 21 is lower than the bottom plane of the vehicle frame 11. The driving member 22 is connected to the vehicle frame 11 and is hinged to both harvesting members, so that the two harvesting shears 21 are opened or closed at the same time and cut the plant stems. Compared with the prior art, by providing a harvesting shear 21 at a position higher than the top plane of the vehicle frame 11, the plant stems are cut and harvested, while providing another harvesting shear 21 at a position lower than the bottom plane of the vehicle frame 11, the portion of the plant stems that is higher than the bottom plane of the vehicle frame 11 is cut, thereby preventing the portion from blocking the path of the cart and hindering the normal movement of the cart, thereby facilitating the cart's movement in the field.

[0091] The specific working process of the present invention is that when in use, the user first pushes the device to move in the field. First, when the guide rod 23 approaches the tobacco stem, as the device moves forward, the tobacco stem is automatically stuck between the first cutter head 213 and the second cutter head 214. Then the user pulls the pull rod 222 by hand. As the pull rod 222 drives the wire rope 221 to rotate, the other end of the wire rope 221 drives the second handle 212 to rotate relative to the first handle 211 to cut the tobacco stem. At the same time, the cutting shears located at the top and bottom of the frame can cut the tobacco stem at the same time. Then the user feeds the wire. Driven by the elastic part 224, the first cutter head 213 and the second cutter head 214 are separated, and the tobacco stem falls to one side. Finally, the user continues to push the device forward. Under the action of inertia, the tobacco stem can be poured into the collecting trough 12. Repeating the above operations can realize the harvesting of tobacco stems in the field, which is convenient and labor-saving.

[0092] The present application uses the above-mentioned device to solve the problem in the prior art that the stems remaining in the soil after being cut are higher than the bottom of the cart, blocking the cart's path and hindering the cart's normal movement, thus causing inconvenience in use.

[0093] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
