Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf root and stem cleaning equipment, and more specifically, to a self-propelled tobacco leaf picking and stalk pulling cleaning machine. Background Art

[0002] Tobacco straw is the roots and stems of tobacco plants left in the soil after the tobacco leaves are harvested. After the current year's harvest, manual labor is required to remove the remaining tobacco straw from the soil to prepare for the next year's tobacco cultivation. Because the roots of tobacco straw are deeply embedded in the soil, it takes considerable force to uproot the tobacco straw. Existing methods for removing tobacco straw primarily rely on mechanically powered straw pullers and manual hoeing.

[0003] In the prior art, motor vehicle heads are mostly tractor heads. However, the growing environment of tobacco leaves is different from that of food crops grown in plain areas. Tobacco leaves are mostly grown in mountainous areas, and terraced planting methods are generally adopted. Tobacco-growing plots in mountainous areas are small, and the tractor heads and straw pullers that provide power for pulling out tobacco stalks are large in size and heavy in weight, and cannot be used in mountain terraces. Secondly, because the roads in mountainous areas are narrow and rugged, the tractor heads and straw pullers that provide power for pulling out tobacco stalks cannot enter the narrow and rugged mountain roads. Therefore, they are difficult to apply to tobacco-growing fields in mountainous areas, and it is impossible to use mechanical power to remove tobacco stalks.

[0004] Therefore, a self-propelled tobacco leaf picking and stalk pulling cleaning machine is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-propelled tobacco leaf picking, stalk pulling and cleaning machine to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a self-propelled tobacco leaf picking, stalk pulling and cleaning machine, comprising a self-propelled trolley body, a gripping adjustment mechanism installed in the self-propelled trolley body, a sliding shaft connected to the gripping adjustment mechanism, a fixed shaft rotatably installed in the self-propelled trolley body, and a plurality of cleaning components connected between the sliding shaft and the fixed shaft;

[0007] There are two sliding shafts and two fixed shafts, and each sliding shaft is arranged in a group with the fixed shaft at the bottom, and the cleaning components installed on the two groups of sliding shafts and the fixed shaft at the bottom are staggered and matched.

[0008] Preferably, the gripping adjustment mechanism includes a hydraulic push-pull rod, a lifting plate and a guide connecting plate. The top end of the hydraulic push-pull rod is installed on the self-propelled trolley body, the bottom end of the hydraulic push-pull rod is installed with a lifting plate, and the bottom end of the lifting plate is installed with multiple guide connecting plates.

[0009] Preferably, the guide connecting plate is symmetrically provided with limiting sliding grooves, and each sliding shaft is respectively inserted into the corresponding limiting sliding groove.

[0010] Preferably, the cleaning assembly includes an upper grab head, a lower grab head, a spring, a connecting hole and an axial hole. A connecting hole is provided at the top of the upper grab head, and an axial hole is provided at the bottom of the connecting hole. The upper grab head and the lower grab head are movably connected, and a spring is connected between the upper grab head and the lower grab head.

[0011] Preferably, the sliding shaft rod is inserted into the connecting hole, and the fixed shaft rod is inserted into the shaft hole.

[0012] Preferably, two springs are provided, and the two springs are connected to both sides of the upper gripping head and the lower gripping head respectively.

[0013] The technical effects and advantages of this utility model are:

[0014] By extending and retracting the hydraulic push-pull rod, the lifting plate can be raised and lowered, thereby causing the bottom of the guide connecting plate to rise and fall accordingly. When the guide connecting plate descends, the sliding shaft rod is pressed down, and the cleaning component is opened under the support of the fixed shaft rod, causing the sliding shaft rod to slide inward, thereby adjusting the tension of the cleaning component and avoiding jamming, thereby improving the smoothness of the structure operation.

[0015] When cleaning the tobacco rhizomes, the upper gripping head is caused to slide inward by the sliding shaft, so that the top of the upper gripping head moves inward, and under the support of the fixed shaft, the lower gripping head connected to the bottom end of the upper gripping head moves outward. During the outward movement, the lower gripping head is blocked by the soil and folded. When it continues to move outward, so that the lower gripping head leaves the soil, under the action of the spring, the lower gripping head fits with the upper gripping head again, and when the sliding shaft moves outward, the upper gripping head moves outward, and the bottom lower gripping head moves inward and grabs into the soil, thereby clamping the tobacco rhizomes. During the process of continuing to grasp, the lower gripping head comes out of the soil and pulls the grasped tobacco rhizomes out of the soil, thereby realizing automatic cleaning of the tobacco rhizomes. The whole process does not require manual labor, thereby reducing the use of labor. The automatic cleaning of mechanical equipment improves the cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] As attached Figure 1-4 The self-propelled tobacco leaf picking, stalk pulling and cleaning machine shown in the figure includes a self-propelled trolley body 1, a gripping adjustment mechanism 3 is installed in the self-propelled trolley body 1, a sliding shaft 4 is connected to the gripping adjustment mechanism 3, a fixed shaft 5 is rotatably installed in the self-propelled trolley body 1, and a plurality of cleaning components 2 are connected between the sliding shaft 4 and the fixed shaft 5; there are two sliding shafts 4 and two fixed shafts 5, and each sliding shaft 4 is arranged in a group with the fixed shaft 5 at the bottom, and the two groups of sliding shafts 4 are staggered with the cleaning components 2 installed on the fixed shaft 5 at the bottom.

[0023] During specific implementation, as the self-propelled trolley body 1 moves automatically, the gripping adjustment mechanism 3 runs along with it, so that the sliding shaft rod 4 is moved by the push-pull force, and the fixed shaft rod 5 supports each cleaning component 2, so that the two rows of staggered cleaning components 2 can be cyclically grasped and released. In this process, when the bottom end of the cleaning component 2 is opened, the bottom soil resistance is reduced, and when grasping, it can directly penetrate into the soil to grasp the tobacco rhizomes. In the process of continuous grasping, it can be automatically lifted, so that the tobacco rhizomes are automatically pulled out of the soil, thereby realizing automatic cleaning of the tobacco rhizomes, reducing the physical effort consumed by manual cleaning, and improving cleaning efficiency and convenience of use.

[0024] The gripping adjustment mechanism 3 includes a hydraulic push-pull rod 301, a lifting plate 302 and a guide connecting plate 303. The top of the hydraulic push-pull rod 301 is installed on the self-propelled trolley body 1, and the bottom of the hydraulic push-pull rod 301 is installed with a lifting plate 302. The bottom of the lifting plate 302 is installed with multiple guide connecting plates 303. The guide connecting plates 303 are symmetrically provided with limiting grooves, and each sliding shaft 4 is respectively inserted into the corresponding limiting groove.

[0025] During specific implementation, the lifting plate 302 can be raised and lowered by extending and retracting the hydraulic push-pull rod 301, so that the bottom of the guide connecting plate 303 can be raised and lowered accordingly. When the guide connecting plate 303 descends, the sliding shaft 4 is pressed down, and the cleaning component 2 is opened under the support of the fixed shaft 5, so that the sliding shaft 4 slides inward, thereby adjusting the tension of the cleaning component 2, avoiding jamming, and improving the smoothness of the structure operation.

[0026] The cleaning assembly 2 includes an upper grab head 201, a lower grab head 202, a spring 203, a connecting hole 204 and an axial hole 205. The upper grab head 201 is provided with a connecting hole 204 at the top, and the connecting hole 204 is provided with an axial hole 205 at the bottom. The upper grab head 201 and the lower grab head 202 are movably connected. A spring 203 is connected between the upper grab head 201 and the lower grab head 202. The sliding shaft rod 4 is inserted into the connecting hole 204, and the fixed shaft rod 5 is inserted into the axial hole 205. Two springs 203 are provided, and the two springs 203 are connected to the upper grab head 201 and the lower grab head 202 on both sides respectively.

[0027] When the upper gripping head 201 is in the soil, the lower gripping head 202 is moved inwards and the lower gripping head 202 is moved outwards by the support of the fixed shaft 5. When the upper gripping head 201 is in the soil, the lower gripping head 202 is moved outwards and the lower gripping head 202 is moved outwards. When the lower gripping head 202 leaves the soil, the lower gripping head 202 is engaged with the upper gripping head 201 again. When the sliding shaft 4 moves outwards, the upper gripping head 201 moves outwards, and the lower gripping head 202 at the bottom moves inwards and grabs the soil, thereby clamping the tobacco rhizome. When the gripping head 201 is in the soil, the lower gripping head 202 comes out of the soil and pulls the gripped tobacco rhizome out of the soil, thereby realizing automatic cleaning of the tobacco rhizome. The whole process does not require manual labor, thereby reducing the use of labor and improving the cleaning efficiency through the automatic cleaning of the mechanical equipment.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
