Description

Technical Field

[0001] The utility model belongs to the technical field of sowing devices, and in particular relates to a small corn sowing machine for hilly and mountainous areas. Background Art

[0002] Most of the corn planting is done by farmers themselves. The cultivated land of each household is scattered and the plot area is small. Therefore, corn planting is limited by the distribution of cultivated land, and it is impossible to carry out centralized cultivation. Large-scale sowing machinery is difficult to complete the work. Due to the inconvenience of transportation in hilly and mountainous areas, soil management is rarely carried out on cultivated land. Cultivated land is mainly affected by sunlight and precipitation, the distance of cultivated land, and the distribution location. The difference in soil moisture in each layer and each piece of cultivated land leads to different spacing between crops. Therefore, the spacing between corn planting in hilly and semi-mountainous areas will be determined according to the soil moisture of each farmland plot, so as to ensure that corn seeds absorb more water to help growth.

[0003] The Chinese utility model patent with publication number CN213187165U discloses a corn seeder, including a machine body, a furrowing plate and a covering plate. A loading box is connected to the middle part of the upper end of the machine body by bolts, a reduction motor is arranged on one side of the loading box, the reduction motor is connected to the machine body by bolts, a transmission output shaft of the reduction motor is connected to gear one by a key, a front wheel is rotatably connected to one side of the bottom end of the machine body, a furrowing plate is arranged on one side of the front wheel, an electric push rod is connected to the upper end of the furrowing plate by bolts, when in use, corn seeds are introduced into the loading box, and then the device is started through the operation panel, the gear one is driven to rotate by the reduction motor, the gear bar is meshed with the gear one and the gear two, so that the gear two can be driven to rotate, and then the rear roller is driven to rotate to realize the movement of the device, the front wheel and the rear roller jointly move the machine body, the moving direction of the device is controlled by the handrail, and when sowing, the height of the furrowing plate can be adjusted by the electric push rod to facilitate furrowing, and the loading box is vibrated by the vibration motor to make the corn seeds flow into the feeding box The corn seeds are placed in the feeding pipe, and the corn seeds are arranged in the feeding pipe. The flow of the feeding pipe is controlled by the electromagnetic valve to control the amount of corn sowing, so that the corn seeds flow into the ditch, and then the soil bag is covered on the corn seeds through the covering plate, and compacted by the rear roller. Since the survival rate of corn seeds is relatively high now, when sowing corn seeds, most of the time, only one corn seed is sown. The corn seeds are controlled by opening and closing the electromagnetic valve, and the amount of sowing. Since more corn seeds are accumulated on the upper side of the electromagnetic valve, when the electromagnetic valve is opened, more corn seeds fall to the bottom of the electromagnetic valve by gravity. Even if the corn seeds fall one by one, it is necessary to manually control the opening time of the electromagnetic valve. Since the opening and closing of the electromagnetic valve is manually controlled through the operation panel, there is a difference in the time of manually controlling the opening and closing of the electromagnetic valve each time, resulting in inconsistent numbers of corn seeds falling, thereby low accuracy of the number of corn seeds sown, and it is difficult to accurately control the planting spacing of corn according to the soil moisture conditions of each farmland.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In addition, the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1

[0025] See also Figures 1 to 5 As shown, a small corn planter for hilly and mountainous areas is proposed, comprising a frame 1;

[0026] The upper part of the frame 1 is provided with a seeding mechanism 6, and the lower part of the frame 1 is provided with a front walking wheel 2, a furrow opener 9, a rear walking wheel 10, and a soil cover 11 in sequence from front to back. The front walking wheel 2 is used as a driving wheel, and its rotating shaft is connected to the driving mechanism;

[0027] The driving mechanism drives the front traveling wheel 2 to rotate, driving the frame 1 to travel as a whole, the furrow opener 9 performs soil furrowing, and after the seeding mechanism 6 drops the corn seeds into the furrow, the soil cover 11 performs furrow leveling to bury the seeds.

[0028] The seeding mechanism 6 includes a bottom plate 601 connected to the upper part of the frame 1, a receiving tube 602 is fixedly connected to the bottom plate 601, a feeding port 6021 is provided at the bottom edge of the receiving tube 602 through the bottom plate 601, a seed scraping plate 605 is provided on one side of the feeding port 6021, the seed scraping plate 605 is fixedly connected to the inner wall of the receiving tube 602, a seed guide tube 7 is connected to the bottom of the feeding port 6021, and the end of the seed guide tube 7 is fixed behind the furrow opener 9. A seeding disc 603 is also arranged in the upper receiving tube 602. The upper surface of the seeding disc 603 contacts the bottom of the seed scraping plate 605. A plurality of holes 6031 are provided along the circumference of the seeding disc 603 corresponding to the feeding opening 6021. The hole diameter of the hole 6031 is larger than the outer diameter of a single corn seed and smaller than the outer diameter of two corn seeds. The center of the seeding disc 603 is connected to the output shaft of the seeding motor 604. The seeding motor 604 is fixed to the lower part of the bottom plate 601.

[0029] When the seeding mechanism 6 is working, corn seeds accumulate at the bottom of the seeding plate 603. During the seed filling process, due to mutual disturbance between populations, there are individual differences between seeds. Multiple seeds will be filled into the same shaped hole 6031 on the seeding plate 603, or multiple seeds will be covered on the shaped hole 6031. The seeding motor 604 drives the seeding plate 603 to drive the seeds in the shaped hole 6031 to move, and also drives the seeds above the shaped hole 6031. When the seeds that have been filled into the shaped hole 6031 pass through the scraper plate 605, the scraper plate 605 will hang off the excess seeds above, completing the seed cleaning stage. The seeds in the shaped hole 6031 leave the seeding plate 603 under the action of gravity and fall into the discharge port 6021 at the bottom, and complete the seeding process through the connected seed guide tube 7, ensuring that one seed falls each time in one working cycle.

[0030] Specifically, the driving mechanism includes a reducer assembly 3 and a travel motor 4. The reducer upper case 301 is connected and closed with the reducer lower case 305. The reducer lower case 305 is connected to the frame 1. The reducer output pulley 302 is connected to the front wheel shaft pulley 304 on the front wheel shaft through the output synchronous belt 303. The reducer input shaft large pulley 306 is connected to the input shaft small pulley 307 connected to the output shaft of the travel motor 4 through the input shaft belt 308.

[0031] By adding a controller and using a plc control program to control the seeding motor 604 and the travel motor 4, the planting spacing of corn can be accurately controlled according to the soil moisture conditions of each farmland plot, making it more convenient for farmers in hilly and mountainous areas to plant corn.

[0032] The furrow opener 9 uses a shoe-type furrow opener 9, which is connected to the bottom of the frame 1 by bolts, and the height of the connection position controller of the furrow opener 9 can be adjusted to control the sowing depth.

[0033] The soil cover 11 is composed of two discs symmetrically connected to the lower end of the frame 1. The two discs are V-shaped and the openings are inclined toward the front end of the frame 1 to prevent the seeds from spreading seriously in the seed furrow. At the same time, it can also make the position of the seeds more regular when they fall to a certain extent, greatly improving the working quality of the seeder.

[0034] In order to facilitate manual operation to control the planting path, a hand support 12 is connected to the upper end of the frame 1.

[0035] The working steps are as follows: turn on the power supply, the power supply supplies power to the travel motor 4 and the seeding motor 604, and the whole mechanism enters the working state; during the working process, the travel motor 4 outputs power to the reducer, and the reducer outputs power to the front wheel axle pulley 304. The travel motor 4 is controlled by the controller to control the travel drive of the whole mechanism, and at the same time the seeding motor 604 starts to work, and the seeding motor 604 drives the seeding disc 603 to move. During the working process, the seeds are accumulated on one side of the seeding disc 603, and are filled with seeds in an orderly manner under the centrifugal effect. After the seeds enter the mold hole 6031, they are brought to the lower feeding port 6021 by the seeding disc 603. The seeds fall from the lower feeding port 6021 into the seed guide tube 7, and fall into the seed furrow opened by the furrow opener 9 through the seed guide tube 7; during the working process, the soil cover 11 turns the furrow opener 9 to the soil on both sides when the whole mechanism moves forward, and completes the soil covering work; according to the needs of different planting environments, the seeding motor 604 and the travel motor 4 are adjusted and controlled by the controller to change the planting spacing.

[0036] Example 2

[0037] Based on Example 1, in this embodiment, in order to enable the present seed drill to better adapt to the complex terrain of hilly and mountainous areas, one end of the base plate 601 is rotatably connected to the top of the support frame 5 fixedly connected to the frame 1, and the other end of the base plate 601 is rotatably connected to the top of the electric push rod 8. The bottom of the electric push rod 8 is installed on the frame 1. The base plate 601 is supported by the electric push rod 8, and the accommodating cylinder 602 on the base plate 601 is adjusted to keep it parallel to the frame 1 during the seeding process.

[0038] At the same time, the seed guide tube 7 is configured as a telescopic tube with ductility to adapt to the change of the inclination of the bottom plate 601.
