Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a corn detasseling device. Background Technology

[0002] The corn tassel is the part at the top of the plant where the male flowers grow. It is shaped like an upside-down broom, light green with reddish tinges. The inflorescence of the corn tassel has a main axis that stands upright. After the male florets mature, their pollen is blown by the wind onto the silks of the female corn ear, completing the pollination process. In corn hybridization breeding, to achieve co-pollination, the corn tassel is often pinched off before it matures.

[0003] Traditional methods of removing corn tassels typically involve bending the corn stalks to reduce the height of the tassels before cutting them. While this method removes the tassels, it requires significant physical exertion and is generally inefficient. It also damages the corn stalks. Therefore, this method is not only prone to damaging the plant but is also cumbersome, time-consuming, and labor-intensive. Furthermore, the tassels removed from the plant are usually discarded indiscriminately, hindering the reuse of straw in the field and making irrigation difficult.

[0004] Therefore, a new demasting device is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a corn detasseling device, the specific solution of which is as follows:

[0006] A corn detassel removal device includes a base frame. A steering rod is rotatably mounted at the front end of the base frame, and a bracket is mounted at the bottom end of the steering rod. A guide wheel is rotatably mounted on the bracket, and a steering handle is mounted at the top end of the steering rod. A front support shaft and a rear support shaft are rotatably mounted on the base frame. Drive wheels and gears are mounted at both ends of the front support shaft, and drive wheels and gears are mounted at both ends of the rear support shaft. The base frame has a perforated structure for gear one and a notch for gear two. A support rod is also mounted on the base frame, and a seat plate is mounted at the top end of the support rod. A cushion is mounted on the top of the seat plate. A sleeve is slidably mounted on the support rod, and a tension spring is fitted at the bottom of the support rod to apply tension to the sleeve. A rotating sleeve is rotatably mounted on the sleeve, and a foot pedal is mounted on the rotating sleeve.

[0039] The aforementioned picking device 37 is used by operators to remove corn tassels. It includes a handle 37-1, a sliding cavity within the handle 37-1, a sliding rod 37-3 slidably mounted within the sliding cavity, a base plate 37-9 at the top of the sliding rod 37-3, a return spring 37-4 within the sliding cavity to apply tension to the sliding rod 37-3, a travel groove 37-1-1 on the side of the handle 37-1, a slider 37-6 passing through the travel groove 37-1-1 on the sliding rod 37-3, and a baffle 37-2 at the end of the handle 37-1. A hinge frame is mounted on the baffle 37-2. A pressure rod 37-5 is provided, and a connecting rod 37-7 is provided between the pressure rod 37-5 and the slider 37-6. The two ends of the connecting rod 37-7 are respectively hinged to the pressure rod 37-5 and the slider 37-6. Multiple elastic rods 37-10 are provided on the base plate 37-9. The telescopic end of the elastic rod 37-10 is provided with a pressure plate 37-11. A cutting blade 37-12 is also provided on the base plate 37-9.

The distance between the base plate 37-9 and the baffle plate 37-2 is closer than the distance between the end of the cutting blade 37-12 and the baffle plate 37-2.

[0040] To facilitate the operation of the picking device 37, the aforementioned pressure rod 37-5 and handle 37-1 are both equipped with finger rings 37-8 for the operator's fingers.

[0041] To facilitate the retrieval of the picking device 37, the handle 37-1 and the seat 9 are connected by the pull rope 40.

[0042] Considering the high position of the seat cushion, a ladder 12 is hinged to the base frame 1 to facilitate workers sitting on the seat cushion. The top of the ladder 12 is provided with a pair of hooks, and the seat plate 9 is provided with a support head 10 for the hooks to be engaged.

[0043] The specific working principle of this invention is as follows: When it is necessary to remove corn tassels, the device is first moved to the edge of the field. Then, according to the soil conditions, the screw rod 33 is rotated so that the plow head 36 extends to an appropriate depth below the ground surface, ensuring that the plow head 36 can plow a trench of appropriate depth to accommodate the crushed tassels. Next, the screw rod 31 is rotated to adjust the position of the soil-removing plate, ensuring that the soil-removing plate can push an appropriate amount of soil from both sides of the trench into the trench to bury the crushed tassels.

[0044] When removing corn tassels, the operator only needs to hold the picking device 37 and press the pressure rod 37-5. The sliding rod 37-3 moves into the sliding cavity. During the process of the sliding rod 37-3 moving into the sliding cavity, the pressure plate 37-11 first presses the tassels tightly against the baffle 37-2. Then the cutting blade 37-12 cuts the tassels to detach them from the corn plant. The cut tassels are then moved to the feeding bin 25-3, and the pressure rod 37-5 is released to allow the tassels to enter the main shell 25-1.

[0045] When the equipment needs to be moved, the operator holds the steering handle 5 with one hand and repeatedly presses the foot pedal 14 up and down with both feet. When the foot pedal 14 is pressed down, the sleeve 7 moves down, the tension spring 18 is compressed, the front one-way transmission assembly 15 moves forward, and the rear one-way transmission assembly 16 moves backward. The gear plate 15-5 in the front one-way transmission assembly 15 drives the gear 21 to rotate, which in turn causes the front support shaft 19 to rotate and the drive wheel 22 to drive the entire device forward. When the foot is released, under the elastic force of the tension spring 18, As the sleeve 7 moves upward, the front one-way transmission assembly 15 moves backward, and the rear one-way transmission assembly 16 moves forward. The toothed plate 16-5 in the rear one-way transmission assembly 16 drives the gear 23 to rotate, which in turn causes the rear support shaft 20 to rotate, and the drive wheel 24 drives the entire device forward. It should be noted that regardless of whether the rear one-way transmission assembly 16 moves forward or backward, the rack in the rear one-way transmission assembly 16 drives the driven gear to rotate, causing the rotating shaft 30 to rotate. The blades 30-1 on the rotating shaft 30 crush the corn tassels.

[0046] In addition, as the equipment moves forward, the plow head 36 plows out a trench, and after being crushed, the male ears fall into the trench. The soil-removing board then pushes the soil on both sides of the trench into the trench to bury the crushed male ears.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
