Description

Technical Field

[0001] The utility model relates to the technical field of corn sowing, in particular to a portable corn sowing device. Background Art

[0002] my country is a large agricultural country. Corn planting has a strong ability to adapt to the environment and can be planted in relatively barren places. Corn accounts for a very large proportion of my country's grain output. In order to increase corn production, agricultural production increasingly relies on agricultural machinery and equipment. There are many types of convenient corn sowing devices currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, it is generally used for a convenient corn sowing device, which sows corn kernels by directly making grooves and placing them in. The row spacing between the grooves for corn sowing cannot be flexibly adjusted, resulting in over-dense planting, which will affect the corn yield. At the same time, there will be good and bad corn seeds, and if they are not screened, there will be problems with the quality of the planted corn. Secondly, since the sowing device is too fast, seeds are prone to splashing, which will result in reduced yields and other problems. Therefore, we propose a convenient corn sowing device to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 The utility model provides a technical solution: a portable corn sowing device, including: a cart 1, a screening box 2, a screen 3, a double-axis motor 4, a cam 5, a mobile frame 6, a spring 7, a fixed frame 8, a seed box 9, a spiral conveyor belt 10, a single-axis motor 11, a seed delivery tube 12, a seed separation box 13, a seed meter 14, a seed delivery hose 15, a planting limit pipeline 16, a fixed block 17, a support frame 18, an electric telescopic rod 19, a support rod 20, a rotating frame 21, a positioning hole 22, a scale 23 and a slotted wheel 24;

[0030] like Figure 1 , Figure 2 and Figure 3As shown in the figure, by pushing the cart 1 to the place where corn needs to be planted, a support frame 18 is symmetrically arranged on the upper right side of the cart 1, and an electric telescopic rod 19 is installed under the support frame 18. The output end of the electric telescopic rod 19 can push the connected support rod 20 to move downward, so that the slotted wheel 24 outside the rotating frame 21 inside the support rod 20 contacts the land. Since the rotating frame 21 is arranged inside the support rod 20, and a plurality of positioning holes 22 are arranged inside the rotating frame 21, and a scale 23 is also arranged on the surface, and the scale 23 and the positioning holes 22 are arranged inside the rotating frame 21. The holes 22 correspond to each other, and the slotted wheel 24 is fixed to the rotating frame 21 by bolts, that is, the bolts fixing the rotating frame 21 and the slotted wheel 24 are unscrewed so that the slotted wheel 24 can slide on the rotating frame 21, and the appropriate distance between the slotted wheels 24 is adjusted according to the scale 23. After the adjustment, the bolts are inserted into the corresponding rotating frame 21 and the slotted wheel 24 to fix the rotating frame 21 and the slotted wheel 24. At this time, the single-axis motor 11 connected to the rear of the rotating frame 21 is turned on, that is, the slotted wheel 24 is rotated, and the slotted wheel 24 can open the planting groove;

[0031] By opening the entrance above the screening box 2 on the left side above the cart 1, the corn seeds are poured into the screening box 2 from the entrance on the screening box 2, and the corn seeds will directly fall on the screen 3 in the screening box 2. At this time, the double-axis motor 4 inside the screening box 2 is turned on, and the double-axis motor 4 will drive the cam 5 symmetrically connected front and back to rotate inside the screening box 2. At the same time, springs 7 are set on the left and right sides of the double-axis motor 4, and the spring 7 connects the double-axis motor 4 and the moving frame 6. Secondly, the outer side of the moving frame 6 is connected to the fixed frame 8, and the moving frame 6 is connected to the fixed frame 8. A spring 7 is also provided at the bottom, and the spring 7 connects the movable frame 6 and the fixed frame 8. In addition, the upper part of the fixed frame 8 is fixed in the screening box 2, and the screen 3 is connected to the lower part of the middle of the dual-axis motor 4, that is, when the cam 5 is started, the screen 3 will vibrate left and right, so as to better screen the corn kernels. In addition, the screen 3 is placed in a sloped manner, and the corn seeds with small particles are directly screened by the vibration of the screen 3 and fall directly through the screen 3 to the bottom of the screening box 2, while the corn seeds with large and full particles directly roll into the seed box 9 on the right side outside the screening box 2 along the slope of the screen 3;

[0032] like Figure 1 , Figure 3 and Figure 5 As shown in the figure, a spiral conveyor belt 10 is connected to the right side of the lower middle part of the seed box 9, and the single-axis motor 11 connected to the spiral conveyor belt 10 is turned on. In addition, a seed delivery tube 12 is also connected to the right side of the upper part of the spiral conveyor belt 10, and the lower part of the seed delivery tube 12 is placed inside the seed separation box 13, that is, when the single-axis motor 11 is started, the corn seeds in the seed box 9 can be transmitted from the seed delivery tube 12 to the inside of the seed separation box 13 through the spiral conveyor belt 10;

[0033] like Figure 1 , Figure 4 and Figure 5 As shown in the figure, the seed delivery tube 12 is divided into three, so that the seed delivery tube 12 can directly deliver the corn into the interior of the seed separation box 13 and divide it into three spaces, and then the single-axis motor 11 connected to the front of the seed meter 14 is turned on, and the seed meter 14 in the three spaces inside the seed separation box 13 will be started, and the seed meter 14 will suck in the corn kernels, and then transmit the corn kernels one by one into the interior of the seed delivery hose 15. At the same time, the seed delivery hose 15 is connected to the planting limit pipe 16, and the corn kernels will be transmitted to the interior of the planting limit pipe 16 through the seed delivery hose 15. The interior of the planting limit pipe 16 is empty, and there is a fixed hole on the upper outer side of the planting limit pipe 16. The fixed block 17 is firmly fixed, that is, the fixed block 17 can fix the planting limit pipe 16 and the setting of the fixed block 17 just corresponds to the scale 23 inside the cart 1. The scale 23 inside the cart 1 and the scale 23 on the surface of the rotating frame 21 are completely corresponding, so the position of the planting limit pipe 16 can be adjusted according to the position of the slotted wheel 24 to ensure that the position of the planting limit pipe 16 is completely consistent with the position of the slotted wheel 24. Since the length of the planting limit pipe 16 is set very close to the slot opened by the slotted wheel 24, the corn in the planting limit pipe 16 can be directly transported to the opened slot without splashing everywhere.
