Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a multifunctional machine for weeding rows. Background Art

[0002] At present, with the development of green agriculture and ecological agriculture, people gradually give up the use of herbicides and other drugs with chemical components for weeding, and often use manual weeding. The labor intensity of manual weeding is very high. In order to reduce people's labor intensity, weeders are now more often used for weeding. In the prior art, a "multifunctional power weeder" is disclosed, with the announcement number of CN 202618103 U and the announcement date of 2012.12.26. The invention patent includes a rotatable rotating shaft, a plurality of weeding hinge wheels with weeding blades are arranged at intervals on the rotating shaft, and support wheels with straight blades are arranged at both ends of the rotating shaft. When working, the rotating shaft rotates, the rotating shaft drives the weeding hinge wheel to rotate, and the weeding hinge wheel drives the rotation of the weeding blade. The weeding blade rotates to remove weeds. When crops are planted in the field, it is difficult for weeds to grow in the place where the crops grow, but it is particularly easy for weeds to grow between the crop rows. This weeder can only be used in fields where no crops are grown, and cannot remove weeds between the rows. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a multifunctional machine for weeding between rows, which solves the technical problem that the prior art cannot remove weeds between rows. The present invention can remove weeds between rows and reduce the number of weeding times during crop growth.

[0004] The objective of the present invention is achieved in this way: a multifunctional machine for row weeding comprises a frame, a plurality of rotatable transmission boxes are connected to the frame, the plurality of transmission boxes are arranged in the same row, one end of the transmission box extending downward and backward is rotatably connected to a connecting shaft, the left and right ends of the connecting shaft are respectively connected to row weeding wheels, the two row weeding wheels are respectively on the left and right sides of the transmission box facing outward, and a plurality of weeding blades are arranged on the periphery of the row weeding wheels.

[0005] In the present invention, the frame is connected to the rear of the traveling device in a liftable manner (this is the prior art, and the traveling device can be a tractor, a rice transplanter or other drivable machine), the row weeding wheels are between the rows of crops, and the two row weeding wheels at the left and right ends of the connecting shaft are on the left and right sides of the crops; when working, the connecting shaft rotates, and the connecting shaft drives the rotation of the row weeding wheels, and the weeding blades continuously rotate to remove the weeds between the rows of crops; the present invention realizes the removal of weeds between the rows by arranging the row weeding wheels and the weeding blades, and reduces the number of weeding times during the growth of crops; it can be applied to the weeding work during the initial growth of crops, and is particularly suitable for the weeding work of rice and wheat.

[0006] In order to further improve the weeding effect, a support rod is connected to the rear side of the transmission box, and a support frame is connected to the rear side of the support rod. Two slides are connected to the downward side of the support frame. The positions of the two slides in the length direction correspond to the two opposite-row weeding wheels respectively. The end of the slide extending forward from the support frame is tilted upward, and the rear part of the slide is tilted upward. In this design, the slide slides forward along the field, and the front and rear ends of the slide are tilted upward. Soil is not easy to accumulate on the slide, thereby reducing sliding resistance. The combined setting of the support frame and the slide provides support for the opposite-row weeding wheels and limits the weeding depth at the same time.

[0007] In order to further realize fertilization, the slide includes a sliding soil part, a fertilizer drop opening is opened on the sliding soil part, a groove part extending downward and bending outward is provided on the sliding soil part corresponding to the front side of the fertilizer drop opening, the groove part is connected with the fertilizer drop opening, and a covering soil part tilted forward and upward is provided on the sliding soil part at the rear side of the fertilizer drop opening, and covering soil parts facing inward and downward are respectively provided on the sliding soil parts on the left and right sides of the fertilizer drop opening, in the front and rear directions, the covering soil part is between the groove part and the covering soil part, two fertilization holes are opened on the support frame, a fertilizer sliding groove inclined backward and downward is opened on the rear side of the support frame, one end of the fertilizer sliding groove is connected with the fertilization hole, the other end of the fertilizer sliding groove extends in the direction of the fertilizer drop opening, and the covering soil part is behind the fertilizer sliding groove; in this design, two relatively arranged groove parts are provided on the sliding soil part, and there is a fertilizer drop gap between the two groove parts, and a weeding blade between the grooves The weeding blade rotates continuously to remove the weeds on both sides of the crop, and the sled slides along the field after the weeds are removed. A fertilizer pipe corresponding to the fertilization hole is connected to the upper side of the support frame, and the cavity of the fertilizer pipe is connected to the fertilization hole. A fertilizer box is arranged in front of the frame, and electric fertilizer applicators with the same number as the fertilizer pipes are arranged on the lower side of the fertilizer box (this is the prior art). The fertilizer dropped by the electric fertilizer applicator is blown into the fertilizer pipe through wind selection, and the fertilizer dropped into the fertilizer pipe enters the fertilization hole. The ditching part opens a fertilizer ditch, and the fertilizer gap between the two ditching parts forms a fertilizer ditch. The fertilizer slides into the fertilizer ditch along the fertilizer sliding groove, and the soil covering part moves the soil on both sides toward the direction of the fertilizer ditch, and the soil covers the fertilizer in the fertilizer ditch. The soil covering part tightly covers the soil on the fertilizer that has just been covered with soil. The synchronous actions of opening fertilizer ditch, covering soil and covering soil are realized through the setting of the sled, and the structure is ingenious and the efficiency is high.

[0008] As a further improvement of the present invention, the frame can swing left and right, and the amplitude of the swing of the frame left and right is adjustable.

If the frame tilts left and right, the working heights of various weeding components are different. A gyroscope for detecting the horizontality of the frame is connected to the upper side of the frame. The gyroscope detects the inclination of the frame, controls the action of the hydraulic cylinder, extends or retracts the push-pull rod, and the frame performs a corresponding swinging action to adjust the horizontality of the frame, so that the frame remains horizontal during operation, the working heights of the sleds are the same, and the operation effect is improved.
