Description

Technical Field

[0001] The invention relates to the technical field of rotary tillers, in particular to a self-adaptive floating rotary tiller. Background Art

[0002] A rotary tiller is an agricultural machine that uses a matching agricultural vehicle (such as a tractor) to provide forward motive force and drives the rotary tiller blade to turn over the soil and break up mud and weeds through a drive device. It can throw the cut soil backwards to collide with the mud guard to further break up the soil. Then, the leveling plate will drag and scrape the surface to make it flat, completing the plowing and harrowing operations at one time. Whether in plains, hills or mountains, a rotary tiller can be used to complete basic operations such as tilling, weeding and leveling.

[0003] Application number: CN202411260251.3, discloses an adaptive floating rotary tiller, including a crawler frame, a rotary tiller, and a hanging rod and an arc-shaped sliding limit block connecting the rotary tiller and the crawler frame. By arranging a movably connected hanging rod and an arc-shaped sliding limit block at the connection between the crawler frame and the rotary tiller, when the crawler frame walks on an uneven ground, taking the crawler frame reaching a high area from a low area as an example, at this time, the rotary tiller is still in the low area, and the crawler frame is in the high area, the entire crawler frame including the arc-shaped sliding limit block connected to the rotary tiller will tilt upward relative to the rotary tiller, and at this time the arc-shaped sliding limit block will move relative to the hanging rod, so that the hanging rod moves downward in the arc-shaped sliding limit block to complete self-adjustment, and at this time the blade of the rotary tiller is still in contact with the land in the low area to perform tillage operations.

[0004] Although the above patented rotary tiller can perform effective automatic adjustment and effectively cultivate uneven areas such as potholes and slopes, the dirt attached to the plow body cannot be removed in time when the rotary tiller is working, which will directly affect the plowing effect and often requires a second pass, wasting the worker's time and consuming a lot of energy. Summary of the invention

[0005] The purpose of the present invention is to provide an adaptive floating rotary tiller to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tool, a telescopic groove is opened in the middle part of the inner part of the tool, a spring is arranged in the telescopic groove, the top of the spring is connected to the telescopic plate, the two sides of the telescopic plate are connected to the connecting rod, the connecting rod extends from the extension openings opened on the two sides of the telescopic groove of the suspension bracket, and the outer side of the connecting rod is connected to the cleaning plate; and a suspension bracket, a tool shaft is arranged in the middle part of the bottom of the suspension bracket, and a plurality of tool holders are arranged on the tool shaft.

[0007] Preferably, a support frame is provided in the middle of the top of the front end of the suspension bracket, a transmission shaft is provided in the middle of the support frame, and the suspension bracket is connected to the telescopic cylinder of the tractor through the transmission shaft, so that the tractor can drive the suspension bracket to move.

[0009] Preferably, a fixing slot is provided on one side of the mounting block and on the bottom of the tool. When the tool is inserted into the mounting slot, the fixing slot on the side of the mounting block overlaps with the fixing slot on the bottom of the tool. Inserting a fixing bolt into the overlapping fixing slot can fix the tool.

[0010] Preferably, the cleaning plate is clamped around the outer side of the tool, and the telescopic plate can drive the cleaning plate to telescope around the outer side of the tool through the connecting rod by squeezing the spring, so that the cleaning plate can clean the dirt adhered to the tool.

[0011] Preferably, telescopic plates are provided on both sides of the suspension bracket between the telescopic groove and the outer surface of the suspension bracket, and multi-stage telescopic plates are provided at both ends of the telescopic plates. The multi-stage telescopic plates are composed of multiple groups of telescopic plates, and the inner sides of the two groups of multi-stage telescopic plates are connected to the two ends of the connecting rod at the same time.

[0012] Preferably, the multi-stage telescopic plates, the telescopic plates inside the two groups of multi-stage telescopic plates are simultaneously connected to both sides of the connecting rod and are disconnected from the middle of the connecting rod. The multi-stage telescopic plates can block the soil and prevent the soil from entering the telescopic groove along the extension port and hindering the telescopic movement of the telescopic groove.

[0013] Preferably, a contraction groove is opened in the middle of the telescopic plate, and the connecting rod can squeeze the telescopic plate on one side so that the telescopic plate is accommodated in the contraction groove opened in the middle of the other group of telescopic plates, and at the same time pull the telescopic plate at the other end to extend out from the other group of contraction grooves.

[0014] Preferably, limit blocks are arranged on both sides of the inner top of the telescopic plate, and limit blocks are arranged on both sides of the bottom of the telescopic plate. The limit blocks can block the telescopic plate through the limit blocks at the bottom of another group of telescopic plates to prevent the telescopic plate from detaching from the contraction groove opened in the middle of the other group of telescopic plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The adaptive floating rotary tiller proposed by the present invention starts to push the cleaning plate against the soil surface through the insertion of the tool, so that the cleaning plate drives the telescopic plate through the connecting rod to squeeze the spring in the telescopic slot in the middle of the suspension bracket, so that the spring drives the telescopic plate to extend and retract downward, and at the same time, the extension opening starts to squeeze the multi-stage telescopic plate connected to one side of the bottom end of the slide slot, so that the multi-stage telescopic plate shrinks to another group of telescopic plates, and at the same time, the multi-stage telescopic plate connected to the top is pulled so that the telescopic plates in the group of multi-stage telescopic plates extend from the other group of telescopic plates, so that the two groups of multi-stage telescopic plates always close the extension openings opened on both sides of the suspension bracket to prevent soil from entering the telescopic slot along the extension opening and blocking the extension and retraction of the spring in the telescopic slot; when the tool shaft drives the tool holder to continue to rotate and the tool is separated from the soil, the spring in the telescopic slot rebounds the telescopic plate, so that the telescopic plate drives the cleaning plate to extend and retract synchronously through the connecting rod, so that the cleaning plate cleans the soil attached to the surface of the tool.
