Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco field planting, in particular to a tobacco field rotary tillage and weed removal device. Background Art
[0002] Due to the high economic value of tobacco, many tobacco growing areas are in a continuous cropping mode, which leads to a large number of pathogens and insect eggs remaining in the soil of tobacco growing areas. Therefore, after the collection is completed, the fields need to be pulled out and rotary tilled to kill pathogens and insect eggs in the soil using sunlight and the low temperature environment in winter. However, compared with other annual herbaceous plants, tobacco plants are large in size and have a well-developed root system. At present, it is difficult for rotary tillage equipment to screen out the remaining underground roots relatively intact, resulting in the phenomenon that pests and diseases still occur in the next year's farming. Utility Model Content
[0003] The utility model aims to provide a tobacco field rotary tillage and weed removal device. The utility model has a simple structure, improves the existing rotary tillage equipment, and can remove, sort and collect the residual tobacco plant roots and stems while rotary tilling the tobacco field.
[0004] To achieve the above object, the present invention provides the following technical solutions:
[0005] A tobacco field rotary tillage and weed removal device comprises a rotary tillage blade frame detachably connected to a weed removal mechanism via a connector, wherein the weed removal mechanism comprises a screening component and a collecting component disposed between the screening component and the rotary tillage blade frame;
[0006] The screening assembly comprises a top inclined plate hinged to the connector, and a plurality of screening rods arranged at equal intervals are provided at the bottom end of the top inclined plate;
[0007] The collecting assembly comprises a connecting plate fixedly connected to the bottom surface of the top inclined plate, and circular discs are fixedly arranged at both ends of the connecting plate in the length direction, and the bottoms of the two circular discs are connected by an arc-shaped filter screen.
[0008] Preferably, the bottom surface of the top inclined plate is also provided with a connecting frame for assembling a rotating shaft, and one end of the rotating shaft is drivingly connected to an output end of a motor fixed on the top inclined plate;
[0009] A lever group is provided on the shaft of the rotating shaft at the position corresponding to the gap between the screening rods. The lever group consists of a plurality of metal rods arranged on the shaft at equal circumferential intervals. The free ends of the metal rods are bent.
[0010] Preferably, the bottom end of the screening rod is provided with a hook bent toward the rotary tiller frame.
[0011] Preferably, the two discs are further connected via a guide plate arranged close to the screening rod, and the discs, the guide plate and the connecting plate form a semi-enclosed structure with an open top.
[0012] Preferably, an auger is provided inside the semi-enclosed structure, the shaft of the auger is rotatably connected to the center of the disc, and there is a gap between the spiral blades of the auger and the arc filter, and the arc filter is provided with a collecting port near the end of the auger in the conveying direction.
[0013] Preferably, both ends of the auger shaft are exposed to the outside and a plurality of radially extending shifting blades are fixedly provided in the circumferential direction.
[0014] The working process of this utility model is as follows:
[0015] When the staff drives the vehicle or other traction mechanism to move the rotary tillage blade frame, the multiple blades at the bottom of the rotary tillage blade frame will till the land on the path, so that the soil and the remaining tobacco rhizomes therein will move to the surface of the soil. When the screening assembly subsequently moves, the screening rod uses the hook to break up the soil again, and the gap between adjacent screening rods forms a screening structure that can penetrate the soil but can retain the tobacco rhizomes. At the same time, the motor drives the rotating shaft to rotate, so that the rotating metal rod turns the tobacco rhizomes into the semi-enclosed structure. The design of the guide plate is also convenient for guiding the tobacco rhizomes moved by the metal rod.
[0016] Since the paddle is designed to be long, it can touch the ground and rotate as it moves forward, which in turn drives the auger to rotate, squeezing the rhizomes of tobacco plants in the semi-enclosed structure and pushing them toward the collection port. The staff can set a collection bag at the collection port to collect the rhizomes, or they can directly discharge them to the ground for subsequent overall collection.
[0017] Compared with the prior art, the utility model has the following advantages:

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] like Figure 1-4 As shown, a tobacco field rotary tillage and weed removal device comprises a rotary tillage blade frame 1 detachably connected to a weed removal mechanism via a connector 2, wherein the weed removal mechanism comprises a screening component 3 and a collecting component 4 disposed between the screening component 3 and the rotary tillage blade frame 1;
[0025] The screening assembly 3 includes a top inclined plate 31 hinged to the connecting head 2, a plurality of screening rods 32 arranged at equal intervals are provided at the bottom end of the top inclined plate 31, a hook 33 bent toward the rotary tiller frame 1 is provided at the bottom end of the screening rod 32, a connecting frame 34 for assembling a rotating shaft 35 is also provided on the bottom surface of the top inclined plate 31, one end of the rotating shaft 35 is transmission-connected to the output end of the motor fixed on the top inclined plate 31, a lever group is provided on the shaft of the rotating shaft 35 at the gap corresponding to the screening rod 32, the lever group is composed of a plurality of metal rods 36 arranged on the shaft at equal intervals in the circumferential direction, and the free end of the metal rod 36 is bent.
[0026] The collecting assembly 4 includes a connecting plate 41 fixedly connected to the bottom surface of the top inclined plate 31, and discs 43 are fixedly provided at both ends of the connecting plate 41 in the length direction. The bottoms of the two discs 43 are connected by an arc filter 44, and the two discs 43 are also connected by a guide plate 47 arranged near the screening rod 32. The disc 43, the guide plate 47 and the connecting plate form a semi-enclosed structure with an open top, and an auger 45 is arranged inside the semi-enclosed structure. The shaft of the auger 45 is rotatably connected to the center of the disc 43 and there is a gap between the spiral blades of the auger 45 and the arc filter 44.
