Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-7, the automatic parallel cotton topping machine comprises a detection module 1, a topping machine chassis 2, a hydraulic control module 4 and an automatic parallel module 3, two identical detection modules 1 are fixedly installed at the front end of the topping machine chassis 2, the two detection modules 1 are mutually symmetrical, one detection module 1 corresponds to a row of cotton, the detection module 1 comprises a T-shaped fixed support 5, a bolt 7, a slider 6, a groove 8, a movable slide rod 9 and a rotation detection module 10, the middle end of the T-shaped fixed support 5 is fixedly connected with the front end of the topping machine chassis 2 through the bolt 7, the T-shaped fixed support 5 is provided with a groove 8, the slider 6 penetrates through the T-shaped fixed support 5 and is connected with the T-shaped fixed support 5 through the bolt 7 in a sliding manner, the hinged with one end of a movable slide rod 9, the other end of the movable slide rod 9 is provided with a groove 8, the groove 8 is provided outside the groove 8, the groove 8 is provided with a rotation detection module 10, the detection module 10 comprises an angle sensor 11, a spring fixed plate 12, a spring 13, a spring 16, a spring 15 and a spring 15 are hinged rod 15, a hinge rod 35, a hinge rod 35 hinge, a hinge rod 35 hinge, a hinge rod.

When the motor works, the small motor 30 and the direct current motor 37 start to rotate; the topping machine chassis 2 drives the detection module 1, the hydraulic control module 4 and the automatic alignment module 3 to start moving in a cotton field, and the direct current motor 37 starts rotating to drive the rotary blade 19 to rotate, so that the rotary blade 19 meets the cotton tip to achieve the purpose of removing the tip of the cotton; if the cotton deviates from one row side, the cotton on the side is contacted with the soft rod 15 on the corresponding side, so that the soft rod 15 is pushed; the soft rod 15 is fixedly connected with the spring fixing plate 12, and the spring fixing plate 12 is hinged with the hinge block 13, so that the rotating shaft of the hinge block 13 rotates, and the angle sensor 11 is driven to rotate; the angle sensor 11 sends the detected signal to the controller 33 because the angle sensor 11 signal line is connected with the controller 33; the controller 33 receives the signal to convert, and the controller 33 controls the electromagnet of the three-position four-way electromagnetic reversing valve body 34 on the corresponding side to be electrified so as to reverse the oil path and control the movement of the hydraulic oil cylinder 31; due to the hinged connection mode among the hinged rod 18, the hinged rod 18 and the triangular hinged rod 27, the hydraulic oil cylinder 31 drives each hinged part to rotate; therefore, the telescopic amount of the hydraulic oil cylinder 31 can be controlled by controlling the power-on time of one side of the three-position four-way electromagnetic reversing valve body 34, so that the cutting part achieves the aim of line alignment; if the cotton is aligned, the soft rod 15 does not drive the rotating shaft of the hinged block to rotate at the moment, so that the angle sensor 11 cannot collect signals, the controller 33 does not control the electromagnet to be electrified, the three-position four-way electromagnetic reversing valve body 34 returns to the middle position, the hydraulic oil pumped by the hydraulic pump 36 directly flows back to the oil tank 28, and the hydraulic oil cylinder 31 does not move any more; if the cotton deviates from the other side of the row, the cotton on the original side does not push the soft rod 15; because the spring 16 is arranged between the spring fixing plate 12 and the spring fixing plate 12, the spring 16 pushes the spring fixing plate 12 to rotate, so that the angle sensor 11 receives a signal, and the cutting part finally returns to the original position in the same way; the cotton on the other side then pushes on the soft rod 15, which in the same way finally brings the cut portions into alignment with the rows of cotton.

The invention combines hydraulic control with agricultural machinery, can realize the function of automatically aligning cotton rows, can achieve the aim of accurately removing the tip, has reliable work, improves the working quality and has the advantage of high intelligence; the invention designs a set of special cutting device, different from the traditional flat cutting mode, the invention adopts three small motors 30 to drive the rotary blades 19 respectively, the center of the cotton can be cut off by the middle rotary blade 19, the tops of the cotton at both sides can be cut off by the rotary blades 19 at both sides when working, thereby achieving better agricultural effect than that of only flat cutting tops, in addition, because the Z-shaped connecting rod 21 and the rotary rod 25 are connected by the rotary disk 26, the angles of the rotary blades 19 at both sides can be changed by rotating the rotary disk 26, thereby being capable of well corresponding to cotton at different periods and different heights.
