Description

Technical Field

[0001] This invention relates to the field of seeding technology, specifically a quantitative seeder for barley cultivation. Background Technology

[0002] A seed drill is a planting machine that sows crop seeds. Seeders used for a specific type or crop are often named after the crop species, such as grain row seeders, corn hill seeders, cotton seeders, and forage spreaders. Barley is one such crop. Short-awned barley grass, also known as wild barley, wild rye, or wild wheatgrass, is distributed in low-lying, damp grasslands of Northeast my country, North China, and Xinjiang. Wild species are also found in the Caspian Sea region of the former Soviet Union, Siberia, and Mongolia. In recent years, it has been introduced and domesticated in northern my country, exhibiting characteristics such as a short growing season, salt and alkali tolerance, and soft forage texture, making it a good perennial gramineous forage grass suitable for both grazing and mowing.

[0003] Existing barley seeders cannot guarantee a balanced distribution of barley seeds across the entire planting area. Planting density affects the subsequent growth of barley, which in turn affects crop yield. They are also inconvenient to use. Therefore, there is an urgent need to develop a quantitative barley seeder to overcome the shortcomings in current applications. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative seeder for barley cultivation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0019] A drive box, which is fixedly mounted on the seeding box, and a telescopic cylinder is provided inside the drive box; and

[0020] A push-pull component, one side of which is fixedly connected to a plurality of metering cylinders, and the other side of which is fixedly connected to a telescopic cylinder.

[0021] As a further aspect of the present invention: the weight monitoring component includes:

[0022] A detection support plate is fixedly installed on the inner wall of the seeding box, and the detection support plate is located below the L-shaped sealing plate;

[0023] Square slots, the number of which is equal to the number of the seeding tubes, are located directly above the seeding tubes, and the square slots are evenly distributed on the detection support plate.

[0024] A material cylinder, which is located inside the square slot and is installed in conjunction with the metering cylinder;

[0025] A discharge pipe, one end of which is fixedly connected to the bottom end of the material cylinder, and the other end of which is inserted into the seeding funnel; and

[0026] The monitoring unit is connected to the detection support plate and the material cylinder respectively.

[0027] As a further aspect of the present invention: the monitoring unit includes:

[0028] The support is provided in multiples, with two supports forming a group, and each group of supports is located on both sides of the material cylinder.

[0029] A connecting plate, one end of which is fixedly connected to the material cylinder; and

[0030] A weight detector is located on the bracket and is also fixedly connected to the connecting plate.

[0031] As a further aspect of the present invention: the accelerated discharge component includes:

[0032] An accelerated exhaust pipe, which runs through the seeding duct;

[0033] An accelerating leak pipe is fixedly connected to the inner wall of the sowing leak pipe and communicates with the sowing leak pipe, and the accelerating leak pipe is located below the accelerating exhaust pipe.

[0034] A drainage head, located inside the seeding drain pipe and fixedly connected to the bottom end of the accelerating exhaust pipe, is also inserted into the accelerating drain pipe; and

[0035] A pressurizing unit is fixedly connected to the seeding box and the accelerated exhaust pipe, respectively.

[0036] As a further aspect of the present invention: the pressurization unit includes:

[0037] The fan is fixedly installed on the seed box;

[0038] A control air box is fixedly connected to the seeding box, and the control air box is also fixedly connected to the output end of the fan through a pipe;

[0039] A connecting hose is provided, with its two ends fixedly connected to the control air box and the acceleration exhaust pipe, respectively. The on / off state of the connecting hose is controlled by a controller installed on the control air box, and the controller is electrically connected to the weight monitoring component.

[0040] As a further aspect of the present invention, it also includes: two support plates, the two support plates being fixedly installed at both ends of the seeding box; and

[0041] A roller is rotatably connected to the support plate.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] When barley seeds need to be sown, firstly, the entire equipment can be moved to the field and connected to the traction machine via the traction frame. Then, the flip cover is opened, and the barley seeds can be placed on the partition inside the sowing box and spread evenly. At this time, some barley seeds will flow into the feeding cylinder and through the partition into the quantitative discharging component, where a portion of the barley seeds will be stored. When the traction machine pulls the sowing box in the field, the quantitative discharging component is activated, allowing a portion of the previously stored barley seeds to fall into the weight monitoring component. At this time, the barley seeds on the upper part of the partition cannot enter the quantitative discharging component through the feeding cylinder, creating a temporary blockage. Once all the barley seeds in the quantitative discharging component have fallen into the weight monitoring component and the quantitative discharging component returns to its original position, a portion of the barley seeds on the partition can re-enter the quantitative discharging component, thus enabling control over the amount of seeds discharged each time. The barley seeds entering the weight monitoring component flow evenly into the soil through the sowing tube. During the sowing and discharging process, when multiple weight monitoring components detect different weights of the remaining barley seeds, the corresponding accelerated discharging component can be activated to increase the discharging speed of the sowing tube corresponding to the heavier weight monitoring component. This ensures that after the sowing box has moved a certain distance, a fixed amount of barley seeds are discharged into the soil, facilitating the flow of barley seeds from the next round of quantitative discharging components into the weight monitoring components. This cycle divides the planting area into several small zones, and the planting situation in each zone is controlled by the quantitative sowing mechanism, gradually increasing the size of the zones. This ensures a balanced distribution of barley throughout the planting area, preventing significant differences in planting density within larger areas. It also ensures balanced nutrition for barley seedling growth, thereby increasing crop yield and providing convenience for users. Attached Figure Description

Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0053] Please see Figures 1-6 The present invention provides a quantitative seeder for barley cultivation, comprising a seed box 1, wherein multiple seeding tubes 8 are evenly distributed on the seed box 1, and further comprising:

[0054] A U-shaped frame 21 is fixedly connected to the interior of the seed box 1. Adjacent U-shaped frames 21 are connected by connecting plates 20. A feed cylinder 22 is fixedly installed on the U-shaped frame 21. The feed cylinder 22 has a partition, which is connected to the inner wall of the seed box 1. Barley seeds are distributed on the upper part of the partition.

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

[0056] The quantitative feeding component is connected to the seeding box 1 and the U-shaped frame 21 respectively. The weight monitoring component is located inside the seeding box 1 and between the seeding tube 8 and the quantitative feeding component. The weight monitoring component is connected to the seeding box 1 and the seeding tube 8 respectively.

[0057] The barley seeds on the upper part of the partition flow into the quantitative discharge component through the feed cylinder 22. The quantitative discharge component discharges the quantitative amount of 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. The acceleration discharge component achieves the same seed discharge volume in the sowing box 1 within a certain planting distance by changing the discharge speed of the sowing tube 8.

[0058] Please see Figure 1 and Figure 2 It also includes: a flip cover 2, which is rotatably mounted on the top of the seeding box 1; and

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

[0060] When barley seeds need to be sown, firstly, the entire equipment can be moved to the field and connected to the traction machine via the traction frame 12. Then, the flip cover 2 is opened, and the barley seeds can be placed on the partition inside the sowing box 1 and spread evenly. At this time, some barley seeds will flow into the feed cylinder 22 and through the partition into the quantitative discharging component, where a portion of the barley seeds will be stored. When the traction machine pulls the sowing box 1 to move in the field, the quantitative discharging component is activated, allowing a portion of the previously stored barley seeds to fall into the weight monitoring component. At this time, the barley seeds on the upper part of the partition cannot enter the quantitative discharging component through the feed cylinder 22, forming a temporary blockage. After all the barley seeds in the quantitative discharging component have fallen into the weight monitoring component and the quantitative discharging component returns to its original position, a portion of the barley seeds on the partition can re-enter the quantitative discharging component, thus enabling the measurement of the amount of seeds discharged each time. Under the control of the quantitative discharging mechanism, barley seeds entering the weight monitoring component will flow evenly into the soil through the sowing tube 8. During the sowing and discharging process, when multiple weight monitoring components detect different weights of the remaining barley seeds, the corresponding accelerated discharging component can be activated to increase the discharging speed of the sowing tube 8 corresponding to the heavier weight monitoring component. This ensures that after the sowing box 1 has moved a certain distance, all the quantitatively measured barley seeds are discharged into the soil, so that the barley seeds in the next round of quantitative discharging components can flow into the weight monitoring component. This cycle can divide the planting area into several small areas, and the planting situation in each area is controlled by the quantitative sowing mechanism. From small to large, this ensures that the barley is evenly distributed throughout the planting area, preventing large differences in planting density in large areas. This ensures the balanced nutrition required for barley seedling growth, thereby increasing crop yield and providing convenience for users.

[0061] In one embodiment of the present invention, please refer to Figure 2 , Figure 4 and Figure 5 The quantitative discharging component includes:

[0062] The sliding partition 23 is fitted onto the U-shaped frame 21 via a guide groove 24 and is slidably connected to the U-shaped frame 21.

[0063] A metering cylinder 26 is fixedly connected to the sliding partition 23, and the top end of the metering cylinder 26 is detachably connected to the feed cylinder 22. A rotating cover 27 is rotatably installed at the bottom end of the metering cylinder 26.

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

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

[0066] The telescopic drive unit includes:

[0067] A drive box 3, which is fixedly mounted on the seed box 1, and a telescopic cylinder is provided inside the drive box 3; and

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

[0069] Please see Figure 1 and Figure 3 The weight monitoring component includes:

[0070] The detection support plate 13 is fixedly installed on the inner wall of the seed box 1, and the detection support plate 13 is located below the L-shaped sealing plate 25;

[0071] Square slots 14, the number of which is equal to the number of the seeding tubes 8, and located directly above the seeding tubes 8, and the plurality of square slots 14 are evenly distributed on the detection support plate 13.

[0072] The material cylinder 15 is located inside the square slot 14 and is installed in conjunction with the metering cylinder 26;

[0073] A discharge pipe 19, one end of which is fixedly connected to the bottom end of the feed cylinder 15, and the other end of which is inserted into the seeding tube 8; and

[0074] The monitoring unit is connected to the detection support plate 13 and the material cylinder 15 respectively.

[0075] Please see Figure 3 The monitoring unit includes:

[0076] The bracket 17 is provided in multiples, with each pair of brackets 17 forming a group, wherein each group of brackets 17 is located on both sides of the material cylinder 15.

[0077] Connecting plate 18, one end of which is fixedly connected to the material cylinder 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 via 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 seeding box 1 moves a certain distance is also fixed. When the seeding box 1 starts to move, the telescopic cylinder is activated, which pushes multiple metering cylinders 26 to move simultaneously via the push-pull component 28. The sliding partition 23 works in conjunction with the guide groove 24 to ensure the smooth movement of the metering cylinders 26. On the other hand, as the sliding partition 23 gradually moves, it can block the feed cylinder 22 to prevent the barley seeds on the partition from being planted. When barley seeds leak from the metering cylinder 26, as the metering cylinder 26 gradually moves away from the L-shaped sealing plate 25, the rotating cover 27 will rotate and open under the gravity of the barley seeds inside the metering cylinder 26, allowing the metered barley seeds inside the metering cylinder 26 to fall into the feed cylinder 15. Conversely, when the telescopic cylinder pulls the metering cylinder 26 in the opposite direction through the push-pull part 28, the rotating cover 27 will seal the bottom of the metering cylinder 26 again, and when the through hole on the sliding partition 23 moves to directly below the feed cylinder 22, the barley seeds on the upper part of the partition will enter the metering cylinder 26 through the through hole on the feed cylinder 22 and the sliding partition 23.

[0080] When a fixed amount of barley seeds are poured into the feed cylinder 15, the weight of the feed cylinder 15 will increase. At this time, as the seeding box 1 moves forward, the barley seeds in the feed cylinder 15 will also enter the seeding drain pipe 8 through the discharge pipe 19 and eventually enter the soil. As the amount of seeds planted in the feed cylinder 15 decreases, the weight detector 16 will monitor the feed cylinder 15. When the weight of one feed cylinder 15 is greater than that of other feed cylinders 15, the corresponding accelerated discharge component of the seeding drain pipe 8 will be activated to increase the discharge speed in the corresponding seeding drain pipe 8. As a result, when the seeding box 1 moves within a certain distance, the discharge speed of seeds in multiple feed cylinders 15 is approximately equal. With balanced planting within each small distance, the planting density in the entire planting area is also approximately balanced. This process of breaking down large quantities into smaller ones improves the efficiency of the seeding work.

[0081] In one embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 6 The accelerated discharge component includes:

[0082] Accelerated exhaust pipe 9, which runs through the seeding duct 8;

[0083] Accelerating leak pipe 29 is fixedly connected to the inner wall of the sowing leak pipe 8 and communicates with the sowing leak pipe 8. The accelerating leak pipe 29 is located below the accelerating exhaust pipe 9.

[0084] A drainage head 30 is located inside the seeding drain pipe 8 and is fixedly connected to the bottom end of the accelerating exhaust pipe 9. The drainage head 30 is also inserted into the accelerating drain pipe 29.

[0085] A pressurizing unit is fixedly connected to the seeding box 1 and the accelerated exhaust pipe 9.

[0086] Please see Figure 1 and Figure 2 The pressurization unit includes:

[0087] Fan 4, which is fixedly installed on the seed box 1;

[0088] A control air box 7 is fixedly connected to the seed box 1, and the control air box 7 is also fixedly connected to the output end of the fan 4 through a pipe;

[0089] A connecting hose 10 is provided, with its two ends fixedly connected to the control air box 7 and the acceleration exhaust pipe 9, respectively. The on / off state of the connecting hose 10 is controlled by a controller 11 installed on the control air box 7, and the controller 11 is electrically connected to the weight monitoring component.

[0090] Under the monitoring of the weight detector 16, the corresponding controller 11 can be activated, thereby controlling the opening and closing of the connecting hose 10 or the size of the opening. When the connecting hose 10 is opened, the high-pressure gas generated by the blower 4 will enter the connecting hose 10 through the pipe and the control air box 7, and then enter the accelerating exhaust pipe 9 through the connecting hose 10. Finally, it will be introduced into the accelerating drain pipe 29 through the drain head 30. The accelerating drain pipe 29 is equipped with an inclined baffle (not shown in the figure), which can divide the space of the accelerating drain pipe 29 into a barley seed discharge channel and an airflow channel. Near the lower outlet of the accelerating drain pipe 29, the airflow can mix with the barley seeds, thereby impacting and assisting in the transport of the barley seeds, allowing the barley seeds to flow quickly into the soil in the sowing drain pipe 8. Figure 6 The accelerating discharge tube 29 in the middle has a transversely split structure. The method used here is to push the seeds to flow quickly by air pressure. Other existing technologies can also be used to increase the seed discharge speed, which will not be elaborated on here.

[0091] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 It also includes: support plates 5, wherein there are two support plates 5, and the two support plates 5 are fixedly installed at both ends of the seeding box 1; and

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

[0093] With the support plate 5 and rollers 6 installed, when the bottom end of the seeding tube 8 moves in the soil, the rollers 6 contact the ground and rotate, thereby improving the longitudinal force condition of the traction frame 12 and ensuring the smooth movement of the seeding box 1.

[0094] It should be noted that, in this invention, unless otherwise explicitly specified and limited, the terms "sliding," "rotating," "fixed," and "equipped" should be interpreted broadly. For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.
