Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a modular automatic narrow spot seeding machine. Background Art

[0002] With the advancement of agricultural modernization and the improvement of agricultural production efficiency, the market for automated seed drills has shown a steady growth trend. The fully automated seed drills currently available on the market are large in size, difficult to carry, and can generally only be used on flat and wide farmland; they may be unstable on steep slopes and wet fields.

[0003] The northwestern region of Shanxi Province has abundant per capita arable land resources, but is affected by low temperature, drought, and steep slopes, and there is very little land available for production. Generally, the land utilization rate is effectively improved by intercropping beans and other legumes between corn stalks, solving the problem of full utilization of available land in the Loess Plateau area and improving soil nutrients based on the characteristics of legumes. Intercropping in the land is a rational way of using land. When planting corn, choosing to intercrop beans will not only not delay the growth of corn, but also promote the growth of beans. By matching them without affecting each other, increased production and income can be achieved.

At the same time, agricultural machinery and equipment are gradually becoming automated and intelligent, and fully automated seed drills are in line with this development trend.

[0049] Combine the following Figure 1 to Figure 6 The embodiment shown describes the technical solution of the utility model:

[0050] The utility model provides a modular automatic narrow-spot seed drill, comprising: a seed bin mechanism 1; a reciprocating seed taking mechanism 2, which is fixedly arranged at one side end of the seed bin mechanism 1; a speed stratification mechanism 3, which is fixedly arranged at one end of the reciprocating seed taking mechanism 2 away from the seed bin mechanism 1; a planetary gear structure 4, which is arranged at one end of the speed stratification mechanism 3 away from the reciprocating seed taking mechanism 2, and the speed stratification mechanism 3 is rotatably connected with the planetary gear structure 4; a soil rotating mechanism 5, which is fixedly arranged at one end of the planetary gear structure 4 away from the speed stratification mechanism 3; a seed delivery mechanism 6, one end of which is arranged at the soil rotating mechanism 5 away from the planetary gear structure 4, and the other end of the seed delivery mechanism 6 penetrates through one end of the seed delivery mechanism 6 away from the planetary gear structure 4 and is exposed.

[0051] The modular automatic narrow spot seeder provided in the utility model is a fully automatic modular hole-seeding seeder that integrates seed screening, seed arrangement and sowing. It is suitable for sowing a variety of bean seeds, especially for intercropping beans in narrow terrain in fields in northern Shanxi during the corn maturity period, and can effectively improve land utilization.

[0052] The seed bin mechanism 1 is used to place seeds to be sown, and the main body of the overall layout of the module body is cylindrical, and the external frame is a cube frame.

[0053] The overall size is small and exquisite. As a packaging system, it can be used in conjunction with various types of machines. When used with a cart or a tractor, it can achieve continuous and stable single-hole continuous sowing. The modular design can achieve all-in-one sowing in multiple holes, changing the applicable terrain, reducing production costs and improving sowing efficiency. Considering that there are many mountains and rugged terrain in northern Shanxi, the utility model can change the problem of excessive labor costs through the seed delivery mechanism 6, and achieve flexible hole planting and single-hole low-cost sowing.

[0054] The utility model as a whole cleverly uses classic mechanical structures such as the screw rod 206, bearings and flange 301 mechanism for many times, realizing the linkage of functions such as seed screening, seed taking, soil rotation and seed dropping. The screw rod 206 at the top of the machine simultaneously realizes the linkage of up and down movement and cyclic reciprocating seed taking, while the bearing is used to separate the rotation and movement at the bottom. The combination of planetary gears and reduction motor 401 is used to realize multi-speed adjustable rotation, which is suitable for the loosening and sowing process of various types of soil. The bottom end uses a self-designed steel auger piece to rotate the soil, and the seed delivery mechanism 6 at the bottom completes the seed dropping process.

[0055] The seed bin mechanism 1 is designed as an inverted trapezoid, with an opening at the bottom, and is assembled in the upper part of the entire machine, so as to facilitate the seed bin mechanism 1 and the reciprocating seed taking mechanism 2 to maintain a relatively close assembly accuracy, so as to realize the reciprocating seed taking mechanism 2 to rotate a fixed angle for stable seed taking;

[0056] The reciprocating seed taking mechanism 2 is fixedly arranged at one side end of the seed bin mechanism 1 and cooperates with the output end of the seed bin mechanism 1. The seeds placed in the seed bin mechanism 1 can be sent to the speed stratification mechanism 3 through the reciprocating seed taking mechanism 2.

[0057] The speed stratification mechanism 3 is fixedly arranged at one end of the reciprocating seed taking mechanism 2 away from the seed bin mechanism 1. The speed stratification mechanism 3 divides the seeding machine into an upper half and a lower half. The speed stratification mechanism 3 separates the reciprocating seed taking mechanism 2 and the planetary gear structure 4.

[0058] The planetary gear structure 4 is arranged at one end of the speed stratification mechanism 3 away from the reciprocating seed taking mechanism 2, and the speed stratification mechanism 3 is rotationally connected with the planetary gear structure 4, and the planetary gear structure 4 is used to reduce the rotation speed of the soil rotating mechanism 5;

[0059] The soil rotating mechanism 5 is fixedly arranged at one end of the planetary gear structure 4 away from the speed stratification mechanism 3, and is used to dig a hole at a designated position to facilitate subsequent planting;

[0060] One end of the seed delivery mechanism 6 is arranged at the soil rotating mechanism 5 away from the planetary gear structure 4, and the other end of the seed delivery mechanism 6 penetrates through the end of the seed delivery mechanism 6 away from the planetary gear structure 4 to be exposed. After the soil rotating mechanism 5 digs the hole, the seed delivery mechanism 6 is opened and the seeds fall to achieve the purpose of on-demand sowing.

[0061] According to the modular automatic narrow spot sowing machine provided by the utility model: the reciprocating seed taking mechanism 2 includes an arc-shaped seed taking disc 201, a first connecting plate 202, a connecting pipe 203, an arc-shaped track sleeve 204, a stepping motor 205, a screw rod 206, a square four-way nut 207, a square slide rail frame 208, a second connecting plate 209, a slider 2010, a screw rod 2011, a linear bearing and a base connecting column 2012; the output end of the stepping motor 205 is fixedly connected to one end of the screw rod 206, and the side wall of the screw rod 206 is sequentially provided with an arc-shaped seed taking disc 201, a first connecting plate 202, The arc track sleeve 204 and the linear bearing; a through hole is provided in the middle of the square four-way nut 207, which is threadedly connected to the screw rod 206, and screw rods 2011 are fixedly arranged in the two opposite screw holes of the square four-way nut 207. The other end of the screw rod 206 is fixedly connected to the base connecting column 2012, and the end of the base connecting column 2012 away from the square four-way nut 207 is connected to the second connecting plate 209 through a linear bearing. The second connecting plate 209 is a square connecting plate, and sliders 2010 are arranged at the four corners of the second connecting plate 209. The slider 2010 slides with the square slide rail frame 208 The side wall of the end of the screw rod 206 close to the stepping motor 205 is fixedly provided with an arc-shaped seed-taking disc 201, and the arc-shaped seed-taking disc 201 is provided with a seed-taking hole. The end of the arc-shaped seed-taking disc 201 away from the stepping motor 205 is provided with a first connecting plate 202, and the first connecting plate 202 is fixedly connected to the side wall of the square slide rail frame 208. The screw rod 206 penetrates the first connecting plate 202, and the screw rod 206 is rotatably connected to the first connecting plate 202. A drop through hole corresponding to the seed-taking hole is opened on the surface of the first connecting plate 202, and one end of the connecting pipe 203 is connected to the drop through hole, and the connecting pipe 203 The other end is connected to the inner wall of the base connecting column 2012; the arc track sleeve 204 is sleeved on the outside of the screw rod 206, and two corresponding arc channels are opened on the side wall of the arc track sleeve 204. One end of the arc track sleeve 204 is fixedly set on the end of the first connecting plate 202 away from the stepper motor 205, and the square four-way nut 207 is sleeved in the arc track sleeve 204. The distance between the farthest ends of the two screw rods 2011 is greater than the diameter of the arc track sleeve 204, and the ends of the two screw rods 2011 away from the square four-way nut 207 penetrate the arc channel opened on the arc track sleeve 204.

[0062] The stepper motor 205 is arranged above the square slide rail frame 208. Because the size of the stepper motor 205 is smaller than the two sides of the square slide rail frame 208, a support plate is fixedly set above the square slide rail frame 208. The stepper motor 205 is set in the middle position of the support plate. The output end of the stepper motor 205 is connected to the screw rod 206. After the screw rod 206 penetrates the support plate, an arc-shaped seed plate 201 is fixedly set on the side wall.

[0063] In the initial state, the seed taking hole corresponds to the lower opening of the seed bin mechanism 1. In the utility model, the seeds are first placed in the seed bin mechanism 1, and then two seeds are dropped into the seed taking hole opened on the arc-shaped seed taking plate 201 through the lower opening of the seed bin mechanism 1. Because the utility model is mainly used for beans, and 2 to 3 beans are sown in each hole, two seed taking holes are set, and the stepper motor 205 is started. The seed taking hole is driven by the screw rod 206 to rotate to the falling through hole position opened in the first connecting plate 202, and the seeds are transported to the inside of the base connecting column 2012 through the connecting pipe 203. The connecting pipe 203 is a hollow hose, and then slides all the way to the position of the seed delivery mechanism 6.

[0064] Because the overall up and down movement of the seeding machine to complete the loosening of the soil and to achieve linkage with the arc track sleeve 204 requires high stability, during which the overall mechanism cannot be linked in the x and y directions, aluminum profiles are used as the frame, and the aluminum profile accessories and the second connecting plate 209 are used to connect the four corners of the frame to achieve stable movement in the z-axis direction. In terms of drive, in order to make the overall up and down movement of the mechanism continuous and stable, and the movement amount is more accurate, a stepper motor 205 plus a screw rod 206 and a nut 602 set is used for drive. Considering that the overall weight is borne by the stepper motor 205, a high-power 57 motor is selected.

[0065] After starting the stepper motor 205, the stepper motor 205 drives the screw rod 206 to rotate back and forth, and the arc seeding disc 201 can realize reciprocating seeding; the arc track sleeve 204 is a hollow cylinder, and two arc channels are spirally opened on the surface. The diameter of the arc channel matches the diameter of the screw rod 2011, and the diameter of the arc track sleeve 204 matches the square four-way nut 207 on which the two screw rods 2011 are installed. The base connecting column 2012 is fixedly connected to the screw rod 206. The bottom end of the base connecting column 2012 is rotatably connected to the second connecting plate 209. When the screw rod 206 rotates, it drives the base connecting column 2012 to rotate, and drives the base connecting column 2012 to slowly move downward through the square four-way nut 207 and the screw rod 2011 stuck in the two arc-shaped channels, thereby driving the soil rotating mechanism 5 to dig a hole to achieve the purpose of on-demand seeding. A through hole is opened at the position corresponding to the inner wall of the second connecting plate 209 and the base connecting column 2012 to facilitate the seeds to continue to fall.

[0066] According to the modular automatic narrow spot seeder provided by the utility model: the speed stratification mechanism 3 includes a flange 301 and a bearing, the middle position of one end of the second connecting plate 209 away from the base connecting column 2012 is fixedly connected to the outer wall of the bearing, and the inner wall of the bearing is fixedly connected with the flange 301.

[0067] The speed stratification mechanism 3 in the utility model connects the planetary gear and the second connecting plate 209, and at the same time, it is necessary to prevent the rotation of the planetary gear from affecting the second connecting plate 209. The middle position of the end of the second connecting plate 209 away from the base connecting column 2012 is fixedly connected to the outer wall of the bearing, and the inner wall of the bearing is fixedly connected with a flange 301, which is connected to the base connecting column 2012, so that the seeds can pass through the speed stratification mechanism 3 and fall into the seed delivery mechanism 6.

[0069] The planetary gear structure 4 in the utility model drives the soil rotating mechanism 5 to rotate, digs holes at designated locations for on-demand sowing, and sets the reduction motor 401 and the planetary gear to reduce the rotation speed of the soil rotating mechanism 5, making it easier for users to adjust the rotation speed.

When the small motor is started, the transmission rod 603 is driven to rotate, and the nut 602 threadedly connected thereto moves downward, thereby driving the horizontal connecting rod 6011 to move downward, thereby opening the first side rod 6012 and the second side rod 6013, and the seeds can fall into the dug pit between the first fan-shaped grasping clamp 6014 and the second fan-shaped grasping clamp 6015, so as to achieve the purpose of on-demand sowing.

The two opening plates 604 have the same shape and together form a hollow cone. The first fan-shaped gripping clamp 6014 and the second fan-shaped gripping clamp 6015 are respectively fixed at the middle position of the inner walls of the two opening plates 604. The two opening plates 604 can be opened by opening the first fan-shaped gripping clamp 6014 and the second fan-shaped gripping clamp 6015, and the seeds inside can fall into the ground. When the two opening plates 604 are closed, the top of the opening plate 604 is in close contact with the bottom end of the auger to prevent seeds from leaking through the gap.

[0075] According to the modular automatic narrow spot seeder provided by the utility model: an infrared counting mechanism 7 is fixedly arranged on the side of the reciprocating seed taking mechanism 2, and the infrared counting mechanism 7 and the arc-shaped seed taking disk 201 are on the same horizontal line.

[0076] In the present invention, seed taking needs to be repeated, so the seed taking plate uses a circular structure. In order to realize the infrared counting function, the arc seed taking plate 201 is redesigned to cut off part of the arc. An infrared counting mechanism 7 is fixedly set on the side of the arc seed taking plate 201, that is, a photoelectric switch is used to detect the number of times the arc seed taking plate 201 takes seeds. The infrared counting mechanism 7 and the arc seed taking plate 201 are on the same horizontal line, which is convenient for infrared detection and counting. The infrared counting mechanism 7 is electrically connected to the display, and the display is fixedly set on the surface of the square slide rail frame 208, which can record the number of sowing times. It is equipped with a Bluetooth module and can be remotely controlled through Bluetooth or wifi connection. The number of dropped seeds is recorded through infrared sensing, and the number of dropped seeds is clearly displayed, which is convenient for timely seed replacement and automatic management.

[0077] In the utility model, the stepper motor 205, the reduction motor 401, the small motor and the infrared counting mechanism 7 are all connected to the single-chip microcomputer through wires. The program for driving each part is programmed in the single-chip microcomputer to achieve the purpose of unified control. The model of the single-chip microcomputer is STM32.

[0078] In the utility model, the stepper motor 205 and the small motor adopt independently designed codes to control the speed and the timing and fixed point of the switch through the driver. The reduction motor 401 realizes the switch and multi-level speed regulation through the independently designed speed regulating mechanism. At the same time, the VOD machine can also be equipped with a Bluetooth module for remote control via Bluetooth.

[0079] The working principle of the utility model is as follows: first, the seeds are loaded into the seed bin mechanism 1, and then the stepper motor 205 and the reduction motor 401 are started to transport the seeds to the seed delivery mechanism 6, and the screw 2011 moves down from the top to the bottom of the arc track sleeve 204, driving the second connecting plate 209 to move downward and dig a hole through the soil rotating mechanism 5 at the same time. After the hole is dug, the small motor is started, the first fan-shaped gripping clamp 6014 and the second fan-shaped gripping clamp 6015 are opened, and the seeds will fall into the dug hole. After the first fan-shaped gripping clamp 6014 and the second fan-shaped gripping clamp 6015 are closed, the stepper motor 205 is started again, and after the screw 2011 returns to the top of the arc track sleeve 204, the seeding machine is moved to the next position and repeated.

[0080] The on-demand seed drill provided by the utility model has a three-layer seeding mechanism whose reciprocating rotation cooperates with the up and down movement of the whole machine to quantitatively take seeds from the seed bin and regularly seed, thereby saving power source; the up and down movement of the on-demand seed drill is separated from the rotation of the planetary gear by bearings so as to operate them independently; the combination of the reduction motor 401 and the planetary gear can realize multi-level adjustment of the rotation speed, thereby improving the practicality of the on-demand seed drill.
