Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a seedling loosening and weeding device. Background Art

[0002] Agricultural tillers use manual methods to plow the soil to create a suitable growth environment for plant cultivation. Soil loosening plays an important role in improving the soil's ability to retain water and fertilizer, promoting microbial activity, etc., and has become an indispensable basic link in the modern agricultural production chain.

[0003] When soil loosening equipment encounters compacted soil and dense accumulation of weed roots inside, it will indeed face the difficulties of low efficiency, huge resistance, equipment damage and even inability to operate.

[0004] Compacted soil is harder and denser than normal soil. The teeth, shovels or blades of the loosening equipment will experience increased wear during use. In addition, large pieces of compacted soil are still compacted after loosening, and the equipment needs to be turned back and forth, which increases the overall loosening time and reduces efficiency. In the loosening process, since the teeth, shovels or blades are relatively large relative to weeds, the roots and stems of the weeds inside are easily preserved in an intact state during the loosening process. After mixing with the soil, they are prone to secondary sprouting, competing with the planting effect for nutrients. This requires targeted strategies to solve this problem. For this reason, we propose a seedling loosening and weeding equipment to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a seedling loosening and weeding device to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: a seedling loosening and weeding device, comprising:

[0008] Among them, a separation mechanism composed of several separation frames is provided inside the welding plate, several screening slots are opened on the welding plate, and several connecting brackets are installed at the bottom of the welding plate. The connecting bracket is located between the screening slots and has a group of crushing rollers for weed separation at the bottom. When it is necessary to loosen the soil in the farmland, as the turning over equipment starts to operate, it can drive the connecting frame to loosen and turn the soil. At this time, the driving shaft moves in a circular motion, and can turn the soil under the action of the loosening component and throw it along the direction of the limiting hanging plate. Under the blocking effect of the welding plate, the soil can be turned and evenly distributed in place. In the process of throwing, it can impact the soil blocks that are still compacted, which can play a role in crushing and effectively improve the turning over effect. The soil blocks can enter the separation frame and, under the action of the separation blade, cut the plant roots to reduce the situation of them mixing into the soil and sprouting again. And a group of crushing rollers at the bottom of the connecting bracket can roll on the ground that has not yet been turned over to cut and separate the stems and leaves of the weeds.

[0009] Preferably, the separation frame is rectangular, and is provided with a plurality of elastic connecting pipes, the positions of the connecting pipes corresponding to the screening slots, the connecting pipes are provided with fixing holes, and the fixing holes are internally connected with docking shafts;

[0010] A plurality of curved separation blades are provided on the outer wall of the docking shaft. The separation blades are used to separate weed roots during the screening and crushing of compacted soil blocks, so that they are mixed into the soil and become nutrients. The curved separation blades in the separation frame dynamically cut and screen the incoming soil blocks, effectively solving the problem of soil compaction.

[0011] Preferably, a clamping groove is provided on one side of the inner wall of the welding plate, and the separation frames are all clamped inside the clamping groove. A transmission end block is connected to the side of the inner wall of the separation frame away from the clamping groove. The transmission end block is used to connect several separation frames into a separation mechanism. The spacing between the separation frames is smaller than the gap between the welding plates. Under the action of external force, the transmission end block can drive the separation mechanism to swing, which is used to break up compacted soil blocks. As the transmission end block moves, it can drive the separation blades in the separation mechanism to actively cut the entangled weed roots during the soil block screening process, and cooperate with the swinging movement of the separation frame to achieve staggered segmentation of the roots.

[0012] Preferably, a plurality of sleeve rings are installed on the driving shaft, and a plurality of arc-shaped loosening plates are installed on the outer wall of the sleeve ring. The sleeve rings and the loosening plates constitute a soil loosening component to loosen the soil.

[0013] Preferably, the sleeve rings are symmetrically arranged in pairs on the driving shaft, and the loosening plates on the outer walls of the symmetrically arranged sleeve rings are stretched outward for digging and turning over the soil. The driving shaft drives the arc-shaped loosening plates to move in a circular motion, and the turned-over soil blocks are thrown to the bottom of the limiting hanging plate at high speed, and the soil blocks are broken by the continuous impact force with the welding plate.

[0014] Preferably, the connecting bracket is arranged in a "U" shape, a circular groove is opened at the bottom end of the connecting bracket, and a driving shaft is inserted into the circular groove, the top end of the driving shaft is sleeved with a clamping tube, the bottom of the welding plate is provided with a threaded groove, the clamping tube is threadedly clamped on the bottom of the welding plate, and the top end of the driving shaft is against the bottom of the transmission end block;

[0015] A fixing ring is fixedly connected to the bottom of the pushing shaft, and a clamping roller is provided for rotation inside the fixing ring. The crushing rollers are respectively connected to both ends of the clamping rollers. The pushing shaft at the bottom of the connecting bracket is connected to the crushing rollers through the clamping rollers, and the height is automatically adjusted according to the terrain. This structure synchronously drives the transmission end block to drive the separation frame to swing, ensuring continuous and efficient operation of soil crushing and root cutting under different terrains.

[0016] Preferably, the crushing roller is composed of several metal sheets with rectangular frames, and the inner side of the metal sheets is provided with cutting edges. The weed roots and stems are cut off during the circular motion of the crushing roller. The crushing roller is composed of rectangular metal sheets with cutting edges, and actively draws in and cuts off the stems and leaves of weeds on the surface when rolling.

[0017] Preferably, a group of straight plates are provided at the bottom of the connecting bracket, and a plurality of positioning plates are symmetrically arranged on both sides of the straight plates, the positioning plates are arc-shaped and are connected to connecting ends inside the gaps, and the connecting blocks are clamped on the straight plates, a plurality of fixing tubes are provided on the inner walls of the positioning plates, and rods are inserted into the fixing tubes, a reset frame is connected to the interior of the positioning plates, the reset frame is elastic and fits on the outer wall of the pushing shaft, the reset frame is arc-shaped and is provided with a movable gap between the reset frame and the positioning plates and is connected to a plurality of metal shafts that pass through the fixing tubes, and the outer ends of the metal shafts are connected to separation plates;

[0018] The separation plate is arranged in an arc shape, and metal frosted plates are provided on both side edges of the separation plate. The separation plate can move slightly following the metal shaft. The coiled weeds are further torn into small sections by the metal frosted plates of the separation plate, and finally evenly mixed into the soil to be converted into organic fertilizer.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The invention drives the arc-shaped opening plate to move in a circular motion through a driving shaft, throwing the turned-up soil blocks at high speed to the bottom of the limit hanging plate, and using the continuous impact force with the welding plate to break the soil blocks. The curved separation blades in the separation frame dynamically cut and screen the incoming soil blocks, effectively solving the problem of soil compaction, forming uniform and fine soil fragments, and creating ideal conditions for seedling planting;

[0021] 2. The present invention uses the separation blades in the separation mechanism to actively cut the entangled weed roots during the soil clod screening process. The swinging motion of the separation frame achieves staggered segmentation of the roots. This design significantly reduces the probability of secondary sprouting of roots after mixing with the soil, thus inhibiting weed regeneration at the root.

[0022] 3. The present invention uses a bottom crushing roller composed of a rectangular metal sheet with a cutting edge. When rolling, it actively rolls in and cuts off the stems and leaves of weeds on the surface. Longer weeds are coiled around the outer side of the positioning plate and further torn into small pieces by the metal frosting plate of the separation plate. Finally, they are evenly mixed into the soil and converted into organic fertilizer, realizing the integration of weed control and field fertilization.

[0023] 4. The present invention connects the crushing roller via a driving shaft at the bottom of the bracket through a clamping roller, automatically adjusting the height according to the terrain, and synchronously driving the transmission end block to drive the separation frame to swing, ensuring continuous and efficient operation of soil crushing and root cutting under different terrains;

[0024] 5. The present invention reserves a pesticide spraying port in the equipment, which can spray herbicides or nutrient solution simultaneously during the loosening process.

[0046] like Figure 8As shown, the metal frosted plate crushing roller metal frosted plate 45 is composed of several metal sheets with rectangular frames, and the inner side of the metal sheets is provided with cutting edges.

The metal frosted plate separation plate metal frosted plate 44 metal frosted plate can move slightly with the metal shaft.

[0049] Working principle: First, when it is necessary to loosen the soil of the farmland, as the turning equipment starts to operate, it can drive the connecting frame 1 to loosen and turn the soil. At this time, the driving shaft 3 moves in a circle, and can turn the soil and throw it in the direction of the limit hanging plate 2 under the action of the loosening component. Under the blocking effect of the welding plate 21, the soil can be evenly distributed in place, and in the process of throwing, it can hit the soil blocks that are still compacted, which can play a role in breaking them, and can effectively improve the turning effect. The soil blocks can enter the separation frame 24, and the separation blade 261 can cut the plant roots to reduce their mixing into the soil and secondary sprouting.

As the mud blocks are quickly shaken off inside, the plant roots can remain between the separation blades 261;

[0050] Then, when the crushing roller 45 is attached to and rolls on the ground, the uneven state of the soil surface can drive the driving shaft 42 to move, thereby moving the transmission end block 27 at the top, and driving the separation frame 24 to move inside the welding plate 21, so that the separation blades 261 on both sides can stagger and divide the roots, thereby reducing the possibility of secondary sprouting. In addition, a corresponding drug spraying port can be provided at the bottom of the connecting frame 1, which can spray herbicides or corresponding nutritional drugs during the turning process. In addition, as the crushing roller 45 moves on the ground, the weed stems and leaves can be rolled into it, and the blades inside the metal frame can be used to cut the weeds, thereby achieving the effect of weeding.

[0051] Finally, during the weeding process, some weeds grow taller and can be thrown onto the separation plate 44 during the winding process of the crushing roller 45.
