[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or crop are often named after the crop type, such as grain drills, corn hole seeders, cotton seeders, and forage spreaders. Among them, barley is one of the many crops. Short-awn barley grass is also known as wild barley, wild rye, and Ley wheat grass. It is distributed in low-lying and wet grasslands in Northeast my country, North China, and Xinjiang. Wild species are distributed in the Caspian Sea, Siberia, and Mongolia in the Soviet Union. In recent years, it has been introduced and domesticated in various parts of northern my country. It has a short growth period, is salt-alkali tolerant, and has soft grass quality. It is a perennial grass of the Poaceae family that is good for both grazing and mowing.

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0053] See also Figure 1-Figure 6 The embodiment of the present invention provides a quantitative seeder for barley planting, comprising a sowing box 1, on which a plurality of sowing leakage pipes 8 are evenly distributed, and further comprising:

[0054] A U-shaped frame 21, wherein the U-shaped frame 21 is fixedly connected to the interior of the seeding box 1, and adjacent U-shaped frames 21 are connected via a connecting plate 20, and a feed barrel 22 is fixedly mounted on the U-shaped frame 21, and a partition is provided on the feed barrel 22, and the partition is connected to the inner wall of the seeding box 1, and barley seeds are distributed on the upper part of the partition; and

[0055] A quantitative sowing mechanism, which is connected to the sowing box 1 and the U-shaped frame 21 respectively, wherein the quantitative sowing mechanism includes a quantitative discharging component, a weight monitoring component and an accelerated discharging component;

[0056] The quantitative discharging assembly is connected to the seeding box 1 and the U-shaped frame 21 respectively, the weight monitoring assembly is located in the seeding box 1 and between the seeding leakage pipe 8 and the quantitative discharging assembly, and the weight monitoring assembly is connected to the seeding box 1 and the seeding leakage pipe 8 respectively;

[0057] The barley seeds on the upper part of the partition flow quantitatively into the quantitative discharge component through the feed tube 22, and the quantitative discharge component discharges the quantitative barley seeds into the weight monitoring component. The weight monitoring component monitors the sowing speed of the barley seeds and controls the corresponding acceleration discharge component to move. The acceleration discharge component achieves the same seed discharge volume of the sowing box 1 within a certain planting distance by changing the discharge speed of the sowing leakage pipe 8.

[0058] See also Figure 1 and Figure 2 , further comprising: a flap 2, the flap 2 being rotatably mounted on the top of the seeding box 1; and

[0059] A traction frame 12 is fixedly connected to a side wall of the seed box 1 .

[0060] When it is necessary to sow barley seeds, first, the entire equipment can be moved into the field and connected to the traction machinery through the traction frame 12, then, the flap 2 is opened, the barley seeds can be placed on the partition in the sowing box 1, and evenly spread, at this time, a part of the barley seeds will flow into the feed barrel 22, and flow through the partition into the quantitative discharge component, then a part of the barley seeds are stored in the quantitative discharge component, when the traction machinery pulls the sowing box 1 to move in the field, the quantitative discharge component is started, so that a part of the barley seeds stored previously can fall into the weight monitoring component, at this time, the barley seeds on the upper part of the partition cannot enter the quantitative discharge component through the feed barrel 22, forming a temporary blocking state, when all the barley seeds in the quantitative discharge component fall into the weight monitoring component, and the quantitative discharge component returns to its original position, a part of the barley seeds on the partition can enter the quantitative discharge component again, so that the discharge amount each time can be realized. Under the control of the weight monitoring component, the barley seeds entering the weight monitoring component will flow evenly into the soil through the sowing leakage pipe 8. During the sowing and discharging process, when multiple weight monitoring components detect that the weights of the remaining barley seeds are different, the corresponding accelerated discharging components can be started to increase the discharging speed of the sowing leakage pipe 8 corresponding to the weight monitoring component with a larger weight, so that after the sowing box 1 moves within a certain distance, all the quantitative barley seeds can be discharged into the soil, so that the barley seeds in the next round of quantitative discharging components can flow into the weight monitoring component. In this cycle, the planting area can be divided into several small areas, and the planting situation in each area is controlled by the quantitative sowing mechanism, from small to large, so as to ensure that the barley is evenly distributed in the entire planting area, and there will be no situation where there is a large difference in planting density in a large area, ensuring the balanced nutrition required for the growth of barley seedlings, thereby increasing the yield of crops and providing convenience for users.

[0061] In one embodiment of the present invention, see Figure 2 , Figure 4 and Figure 5 , the quantitative discharge component comprises:

[0062] A sliding partition 23, wherein the sliding partition 23 is clamped on the U-shaped frame 21 through a guide groove 24 and is slidably connected to the U-shaped frame 21;

[0063] A dosing cylinder 26, wherein the dosing cylinder 26 is fixedly connected to the sliding partition 23, and the top end of the dosing cylinder 26 is detachably connected to the feeding cylinder 22, and a rotating cover 27 is rotatably mounted on the bottom end of the dosing cylinder 26;

[0064] An L-shaped blocking plate 25, one end of which is fixedly connected to the U-shaped frame 21, and the L-shaped blocking plate 25 is also slidably connected to the rotating cover 27; and

[0065] A telescopic driving unit is connected to the seed box 1 and the metering cylinder 26 respectively.

[0066] The telescopic drive unit comprises:

[0067] A driving box 3, wherein the driving box 3 is fixedly mounted on the seeding box 1 and a telescopic cylinder is provided in the driving box 3; and

[0068] A push-pull member 28, one side of which is fixedly connected to the plurality of metering cylinders 26, and the other side of which is fixedly connected to the telescopic cylinder.

[0069] See also Figure 1 and Figure 3 , the weight monitoring component comprises:

[0070] A detection support plate 13, wherein the detection support plate 13 is fixedly mounted on the inner wall of the seed box 1, and the detection support plate 13 is located below the L-shaped blocking plate 25;

[0071] A square notch 14, the number of which is equal to the number of the sowing leakage pipes 8, and is located directly above the sowing leakage pipes 8, and a plurality of the square notches 14 are evenly opened on the detection support plate 13;

[0072] The barrel 15 is located in the square notch 14 and is installed in coordination with the metering barrel 26;

[0073] A discharge pipe 19, one end of which is fixedly connected to the bottom end of the barrel 15, and the other end of which is inserted into the sowing drain pipe 8; and

[0074] A monitoring unit is connected to the detection support plate 13 and the barrel 15 respectively.

[0075] See also Figure 3 , the monitoring unit comprises:

[0076] A bracket 17, wherein the number of the brackets 17 is multiple, and every two of the brackets 17 form a group, wherein each group of brackets 17 is located on both sides of the barrel 15;

[0077] A connecting plate 18, one end of which is fixedly connected to the barrel 15; and

[0078] The weight detector 16 is located on the bracket 17 and is also fixedly connected to the connecting plate 18 .

[0079] A portion of the barley seeds on the partition will enter the metering cylinder 26 through the feed cylinder 22 and the sliding partition 23. Since the volume of the metering cylinder 26 is fixed, the amount of barley seeds planted each time the sowing box 1 moves a certain distance is also fixed. When the sowing box 1 starts to move, the telescopic cylinder is started, and the push-pull member 28 can push multiple metering cylinders 26 to move at the same time, and the sliding partition 23 and the guide groove 24 are arranged to work together. On the one hand, the metering cylinder 26 can move smoothly. On the other hand, in the process of the gradual movement of the sliding partition 23, the feed cylinder 22 can be blocked to prevent the partition from When the barley seeds in the metering cylinder 26 gradually move away from the L-shaped blocking plate 25, the rotating cover 27 will rotate and open under the action of the gravity of the barley seeds in the metering cylinder 26, so that the quantitative barley seeds in the metering cylinder 26 can fall into the barrel 15. On the contrary, when the telescopic cylinder pulls the metering cylinder 26 to move in the opposite direction through the push-pull member 28, the rotating cover 27 blocks the bottom end of the metering cylinder 26 again, and when the through hole on the sliding partition 23 moves to the right below the feeding cylinder 22, the barley seeds on the upper part of the partition will enter the metering cylinder 26 through the through holes on the feeding cylinder 22 and the sliding partition 23;

[0080] When a certain amount of barley seeds are poured into the barrel 15, the weight of the barrel 15 will be increased to a certain extent. At this time, as the sowing box 1 moves forward, the barley seeds in the barrel 15 will also enter the sowing leakage pipe 8 through the discharge pipe 19 and finally enter the soil. In the process of continuous reduction of planting in the barrel 15, through the monitoring function of the weight detector 16, when the weight of a barrel 15 is greater than the weight of other barrels 15, the acceleration discharge component corresponding to the sowing leakage pipe 8 will be started to increase the discharge speed in the corresponding sowing leakage pipe 8, so that when the sowing box 1 moves within a certain distance, the seed discharge speeds in multiple barrels 15 are roughly equal. When the planting is balanced within each small distance, the planting density in the entire planting area is also roughly balanced, which is broken down into parts and improves the effect of sowing work.

[0081] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 6 , the accelerating discharge component comprises:

[0082] An accelerating exhaust pipe 9, wherein the accelerating exhaust pipe 9 runs through the sowing leakage pipe 8;

[0083] An accelerating leakage pipe 29, wherein the accelerating leakage pipe 29 is fixedly connected to the inner wall of the sowing leakage pipe 8 and communicates with the sowing leakage pipe 8, and the accelerating leakage pipe 29 is located below the accelerating exhaust pipe 9;

[0084] A drainage head 30, the drainage head 30 is located in the sowing leakage pipe 8 and is fixedly connected to the bottom end of the accelerating exhaust pipe 9, and the drainage head 30 is also inserted into the accelerating leakage pipe 29; and

[0085] A pressurizing unit is fixedly connected to the seed box 1 and the accelerating exhaust pipe 9 respectively.

[0086] See also Figure 1 and Figure 2 , the pressurizing unit comprises:

[0090] Under the monitoring of the weight detector 16, the corresponding controller 11 can be started, so as to control the opening and closing or the size of the opening of the connecting hose 10. When the connecting hose 10 is opened, the high-pressure gas generated by the fan 4 will enter the connecting hose 10 through the pipeline and the control bellows 7, and enter the accelerating exhaust pipe 9 through the connecting hose 10, and finally pass into the accelerating leakage pipe 29 through the drainage head 30, wherein an inclined partition (not shown in the figure) is provided in the accelerating leakage pipe 29, which can divide the space of the accelerating leakage pipe 29 into a discharge channel and an airflow channel for barley seeds. At the lower end outlet near the accelerating leakage pipe 29, the airflow can be mixed with the barley seeds, thereby producing an impact and auxiliary conveying effect on the barley seeds, so that the barley seeds can quickly flow into the soil in the sowing leakage pipe 8, and the attached Figure 6 The accelerating leakage pipe 29 is a transversely cut structure. The method of pushing the seeds to flow quickly by air pressure adopted here can also adopt other methods in the prior art to increase the seed discharge speed, which will not be described in detail here.

[0092] The roller 6 is rotatably connected to the support plate 5 .

[0093] By providing the support plate 5 and the roller 6, when the bottom end of the seeding tube 8 moves in the soil, the roller 6 contacts the ground and rotates, thereby improving the longitudinal stress condition of the traction frame 12 and ensuring the smooth movement of the seeding box 1.
