[0028] Example 1

[0029] like Figure 1-Figure 8 As shown,

[0030] A walking tractor-traction film-covering precision seeding machine comprises a walking tractor 1, a main support frame 2 is fixed on the walking tractor 1, a driver's seat 12 is fixed on the upper end of the main support frame 2, the rear end of the main support frame 2 is rotatably connected to a seeding bracket 1101 of a seeding device 11, and two film pressing wheels 8 are arranged on the main support frame 2. The main support frame 2 connects the seeding device 11 with the walking tractor 1, and the film pressing wheels 8 provide two wheels for the device, thereby improving the stability of the operation of the device. Since the walking tractor 1 does not have a driver's seat 12, the operator needs to stand to use it, which is very tiring. The driver's seat 12 is arranged on the main support frame 2 so that the operator can sit and complete the use and operation of the device, making it easier to sow.

[0031] A sub-support frame 3 is provided at the lower end of the main support, and the main support frame 2 and the sub-support frame 3 are fixedly connected through a sub-frame lifting device 7. The sub-frame lifting device 7 includes a first vertical rod 701, a second vertical rod 703, a first gear plate 704 and a first lifting arm 702. The lower end of the first vertical rod 701 is fixedly connected to the sub-support frame 3, the upper end of the first vertical rod 701 is rotatably connected to the first lifting arm 702, the lower end of the second vertical rod 703 is fixedly connected to the main support frame 2, the upper end of the second vertical rod 703 is rotatably connected to the first lifting arm 702, the first lifting arm 702 is clamped and connected to the first gear plate 704, and the first gear plate 704 is fixedly connected to the main support frame 2.

[0032] like Figure 8As shown, in order to allow the auxiliary support frame 3 to rise and fall smoothly, four movable arms 15 are provided on the main support frame 2, and the movable arms 15 include a first horizontal arm 1501, a first vertical arm 1502, a second vertical arm 1503 and a second horizontal arm 1504. The first horizontal arm 1501 is fixedly connected to the main support frame 2, and the second horizontal arm 1504 is fixedly connected to the auxiliary support frame 3. The first vertical arm 1502 and the second vertical arm 1503 are plugged in, and can move relative to each other as the auxiliary support frame 3 rises and falls, thereby ensuring the stable rise and fall of the auxiliary support frame 3 and preventing the auxiliary support frame 3 from shaking.

[0033] The purpose of setting the auxiliary support frame 3 is to enable film covering sowing. A film covering device is set on the auxiliary support frame 3. However, when the film covering device is not needed, if the film covering device is still moving forward by friction on the ground, it will generate a lot of friction resistance to the device, consume the power of the walk-behind tractor 1, and cause useless work. Therefore, when the film covering device is not used, the auxiliary support frame 3 needs to be lifted up and off the ground. Only the wheels of the walk-behind tractor 1 and the film pressing wheels 8 roll on the ground, which reduces the friction resistance between the device and the ground and realizes energy-saving and efficient operation.

[0034] The sowing device 11 includes a sowing bracket 1101, a sowing roller 1102 and a feed box 1103. The sowing device 11 is a prior art and uses an existing corn precision seeder. The seeds in the feed box 1103 can be put into the sowing roller 1102 and sown through the conical sowing holes on the sowing roller 1102. This corn precision seeder can control the number of seeds sown each time and the distance between each sowing to be equal, without wasting seeds, and achieving precision sowing.

[0035] An adjusting device 13 is provided on the sowing support 1101, and the adjusting device 13 includes a cross bar 1301, which is located at the upper end of the sowing device 11 and is rotatably connected to the main support frame 2. A transverse boom 1303 and a second lifting arm 1302 are fixed on the cross bar 1301, and a vertical boom 1304 is rotatably connected to the transverse boom 1303, and the lower end of the vertical boom 1304 is fixedly connected to the sowing device 11. The function of the adjusting device 13 is to lift or lower the sowing device 11. When the sowing device 11 is needed to sow, it is necessary to control the second lifting arm 1302 to rotate the cross bar 1301, the cross bar 1301 drives the horizontal hanging arm 1303 to move downward, the horizontal hanging arm 1303 drives the vertical hanging arm 1304 to move downward, and the vertical hanging arm 1304 drives the sowing support 1101 to rotate downward until the sowing roller 1102 reaches the required height; when sowing is not needed, the sowing device 11 is lifted to prevent the sowing roller 1102 from being damaged by friction and collision with the ground during the operation of the device, and the second lifting arm 1302 is rotated to drive the cross bar 1301 to rotate, the cross bar 1301 drives the horizontal hanging arm 1303 to rotate upward, the horizontal hanging arm 1303 drives the vertical hanging arm 1304 to move upward, and the vertical hanging arm 1304 drives the sowing support 1101 to rotate upward until the sowing roller 1102 is away from the ground and reaches the required height.

[0036] The lower end of the auxiliary support frame 3 is rotatably connected to a screed plate 4, and the function of the screed plate 4 is to level the land to be sown to prevent the uneven ground from causing different sowing depths to affect the sowing effect.

[0037] like Figure 5 As shown, a second lifting device 14 is provided on the smoothing plate, and the second lifting device 14 includes a third vertical rod 1401, a third lifting arm 1402, a fourth vertical rod 1403 and a second gear plate 1404. The third vertical rod 1401 is fixedly connected to the smoothing plate 4, and the second gear plate 1404 and the fourth vertical rod 1403 are fixedly connected to the main support frame 2. One end of the third lifting arm 1402 is fixedly connected to the upper end of the third vertical rod 1401, and the middle part of the third lifting arm 1402 is rotatably connected to the upper part of the fourth vertical rod 1403 through a rotating shaft. The free end of the third lifting arm 1402 is clamped in the slot of the second gear plate 1404. The second gear plate 1404 is provided with multiple slots of different heights. The height of the smoothing plate can be adjusted according to the different softness of the land, so as to better level the different lands.

[0038] Furrowing plows 5 are fixed on both sides of the auxiliary support frame 3. The furrowing plows 5 are located at the rear end of the screed plate 4. The function of the furrowing plows 5 is to open a shallow furrow to facilitate the fixing of the two sides of the mulch film. The distance between the two furrowing plows 5 can be adjusted according to the width of the mulch film. The furrowing plows 5 are fixed to the auxiliary support frame 3 through a first adjusting bracket. Two square tubes are sleeved at both ends of the first adjusting bracket. The two square tubes are fixed to the first adjusting bracket by bolts. When it is necessary to adjust the distance between the two furrowing plows, just loosen the bolts, adjust the two square tubes to the appropriate position, and then tighten the bolts to fix the square tubes. Always ensure that the shallow furrows opened by the two furrowing plows 5 are slightly narrower than the width of the mulch film, so that the two sides of the mulch film can be easily fixed in the two shallow furrows.

[0039] The film hanging device 6 is fixed on the auxiliary support frame 3 through the second adjustment bracket, and the film hanging device 6 includes a film hanging bracket 601 and a conical plug-in 602, and the conical plug-in 602 is fixedly connected to the film hanging bracket 601. Two square tubes are sleeved at both ends of the second adjustment bracket, and the two square tubes are fixed to the second adjustment bracket by bolts. When it is necessary to adjust the distance between the two film hanging brackets 601, it is only necessary to loosen the bolts, adjust the two square tubes to a suitable position, and then tighten the bolts to fix the square tubes; the second adjustment bracket film hanging device 6 is located at the rear end of the furrowing plow 5. The existing ground film on the market is rolled up and down, and the conical plug-in 602 is convenient for fixing the ground film roll; because the diameter of the ground film roll will gradually decrease during use, in order to ensure that the ground film is always covered closely to the ground, the design of the film hanging bracket 601 can be adjusted in height up and down, so that the ground film roll can always cover closely to the ground, and the film covering effect is better, and the two sides of the ground film just fall into the shallow groove opened by the furrowing plow 5.

[0040] The film pressing wheel 8 is located at the rear end of the film hanging device 6. The film pressing wheel 8 presses the soil dug to one side of the shallow trench by the furrowing plow 5 into the shallow trench with the ground film, pressing the ground film to prevent the ground film from being blown away by the wind, thereby achieving a better film covering effect. The distance between the two film pressing wheels 8 can be adjusted according to the width of the ground film to ensure the film pressing effect.

[0041] The two ends of the auxiliary support frame 3 are fixed with soil burying plates 10, which are located at the rear end of the film pressing wheel 8. The function of the soil burying plates 10 is to lift the soil on both sides of the ground film onto the ground film, with part of it falling on both sides of the ground film and part of it falling into the cylinder wall 901 of the drum 9. As the drum 9 rotates, the inclined plate 902 is provided in the cylinder arm 901, and the soil flows out to the middle of the ground film, thereby fixing the middle of the ground film, better fixing the ground film, and preventing the ground film from being blown away by the wind. The distance between the two soil burying plates 10 can be adjusted according to the width of the ground film to ensure the soil burying effect; at the same time, the height and angle of the soil burying plates 10 can be adjusted. The lower the soil burying plates 10 are and the larger the inclination angle is, the greater the amount of soil burying will be, and vice versa. A roller 9 that cooperates with the soil burying plate 10 is rotatably connected to the auxiliary support frame 3, an inclined plate 902 is provided in the roller 9, a fixed frame 903 is provided in the middle of the roller 9, a bearing 904 is fixed to one end of the fixed frame 903, a cross frame 905 is provided between the two rollers 9, both ends of the cross frame 905 are rotatably connected to the bearings 904 on the two rollers 9, a vertical frame 906 is fixedly connected to the cross frame 905, an adjusting arm 907 is provided at the upper end of the vertical frame 906, the lower end of the adjusting arm 907 is connected to the vertical frame 906 by bolts, and the upper end of the adjusting arm 907 is fixedly connected to the auxiliary support frame 3 by bolts. When it is necessary to adjust the height of the roller 9 according to the land conditions, the height of the roller 9 can be adjusted by adjusting the bolts between the vertical frame 906 and the adjusting arm 907.

[0042] Working principle:

[0043] When the device is only traveling and not performing sowing operations, the auxiliary support frame 3 and the sowing device 11 need to be lifted, and the equipment on the auxiliary support frame 3 and the sowing device 11 need to be away from the ground. First, the first lifting arm 702 is pressed downward. The first lifting arm 702 is a lever structure, and the upper end of the second vertical rod 703 is a fulcrum. The first lifting arm 702 rotates downward and drives the first vertical rod 701 to move upward. The first vertical rod 701 drives the auxiliary support frame 3 to move upward, and the auxiliary support frame 3 drives the second vertical arm 1503 in the movable arm 15 along the first The vertical arm 1502 moves upward until all equipment on the auxiliary support frame 3 is away from the ground, and the first lifting arm 702 is fixed in the slot of the corresponding height of the first gear plate 704; then the second lifting arm 1302 is pressed downward to drive the cross bar 1301 to rotate, and the cross bar 1301 drives the horizontal hanging arm 1303 to rotate upward, and the horizontal hanging arm 1303 drives the vertical hanging arm 1304 to move upward, and the vertical hanging arm 1304 drives the sowing support 1101 of the sowing device 11 to rotate upward, and the sowing roller 1102 is away from the ground.

[0044] When the device is used for film covering and sowing in the farmland, the auxiliary support frame 3 and the sowing device 11 need to be lowered to carry out the film covering and sowing operations. First, the first lifting arm 702 is lifted upward, and at the same time, the first vertical rod 701 is driven downward. The first vertical rod 701 drives the auxiliary support frame 3 to move downward. The auxiliary support frame 3 drives the second vertical arm 1503 on the movable arm 15 to move downward along the first vertical arm 1502. After all the equipment on the auxiliary support frame 3 falls straight to the ground, the first lifting arm 702 is inserted into the slot of the corresponding height of the first gear plate 704 and fixed; then the second lifting arm 1302 is lifted upward to drive the cross bar 1301 to rotate, the cross bar 1301 drives the horizontal lifting arm 1303 to rotate downward, and the horizontal lifting arm 1303 drives the vertical lifting arm 1 304 moves downward, the vertical boom 1304 drives the sowing support 1101 of the sowing device 11 to rotate downward, and the sowing roller 1102 reaches the ground. While the hand tractor 1 moves forward, the screed plate 4 levels the land, the furrowing plow 5 digs shallow furrows for the ground film, and the film hanging device 6 drives the ground film roll to lay the ground film. The two sides of the ground film fall into the shallow furrows opened by the furrowing plow 5, and the film pressing wheel 8 compacts the shallow furrows to fix the ground film. The soil burying plate 10 lifts the soil on both sides of the ground film onto the ground film, part of which falls on both sides of the ground film, and part falls into the drum 9. As the drum 9 rotates, the inclined plate 902 is provided in the drum 9, and flows out to the middle of the ground film, thereby fixing the middle of the ground film, better fixing the ground film, and preventing the ground film from being blown away by the wind.

[0045] The technical solution of the present invention realizes the precise film covering and sowing by the walking tractor 1 by providing a walking tractor 1, a film hanging device 6 and a sowing device 11; and by providing a main support frame 2, a sub-support frame 3 and a sub-frame lifting device 7, the device can lift the screed plate 4, the furrowing plow 5, the film hanging device 6, the soil burying plate 10 and the roller 9 on the sub-support frame 3 during operation without contacting the ground, thereby reducing friction resistance and improving the operating efficiency of the device.
