Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of agricultural machinery, and concretely relates to an automatic seeding device. BACKGROUND

[0002] With the growth of global population and the reduction of agricultural land, improving agricultural production efficiency has become one of the important challenges faced by modern agriculture. Traditional manual seeding methods not only have high labor intensity and low efficiency, but also are difficult to ensure the uniform distribution of seed material and the consistency of planting depth, which directly affects the growth quality and final yield of crops. Therefore, developing an efficient, accurate and easy-to-operate automatic seeding device has become an important direction of the development of modern agricultural technology.

[0003] In traditional agricultural practice, seeding usually relies on manual or simple mechanical tools. This method has the following shortcomings: (1) high labor intensity, traditional seeding methods often require a large amount of manpower for operation, especially in large-scale farmland operations, which not only increases the physical burden of farmers, but also easily leads to low work efficiency due to long-term repetitive labor. (2) uneven distribution of seed material, whether by hand or using simple seeding equipment, it is difficult to accurately control the amount and distribution of seed material. This will lead to some areas with too dense seed material and other areas with too sparse seed material, affecting the growth and development of crops and the final yield. (3) structure is not easy to disassemble, on the one hand, the agricultural production environment is dusty and dirty, and the seeding equipment, especially the part directly contacting the soil and seed material, is easy to be contaminated with dirt. If the equipment is not easy to disassemble, it is difficult to thoroughly clean these critical parts, which may cause corrosion or blockage of the equipment over a long period of time, thereby shortening the service life of the equipment. On the other hand, for large or integrated designed seeding equipment, if its structure is complex and not easy to disassemble, it will bring inconvenience to the transportation, transfer and long-term storage of the equipment. Especially during the non-farming season or when long-distance transportation to other work sites is required, moving such a whole equipment is not only laborious and time-consuming, but also increases the logistics cost and time cost.

[0051] . As shown in Figures 1 to 5 , the present disclosure provides an automatic seeding device, which comprises a vehicle body 10, a storage box 20, a seed distribution disc 30 and a furrowing mechanism 40. The storage box 20 has a storage cavity 21 for containing seed material. The top of the storage box 20 is formed with a filling port 22 communicating with the storage cavity 21. The bottom of the storage box 20 is in the form of a funnel. The furrowing mechanism 40 is arranged on the vehicle body 10. The seed distribution disc 30 is detachably mounted on the vehicle body 10. The seed distribution disc 30 is arranged below the storage box 20. The seed distribution disc 30 has a cavity 31 in the inside. The seed distribution disc 30 is formed with a feeding port 32 and a discharging port 33. Both the feeding port 32 and the discharging port 33 communicate with the cavity 31. The feeding port 32 communicates with the closing part of the funnel structure. The discharging port 33 is arranged to be located behind the furrowing mechanism 40 along the traveling direction of the vehicle body 10.

[0052] Among them, the vehicle body 10 is the basic structure of the whole device, used to install the storage box 20, the seed distribution disc 30 and the furrowing mechanism 40, and supports the whole seeding device to move on the land.

[0053] Among them, the furrowing mechanism 40 is installed on the vehicle body 10, responsible for opening a groove suitable for planting seed material in the soil.

[0054] The feeding port 32 of the seed distribution disc 30 is directly connected to the funnel structure of the bottom of the storage box 20 to receive the seeds, and the discharging port 33 of the seed distribution disc 30 is arranged behind the furrowing mechanism 40 in the traveling direction of the vehicle body 10, so as to ensure that the seeds can be accurately dropped into the furrow.

[0055] According to the above technical scheme, the storage box 20 is provided, and the storage box 20 has a storage cavity 21 for accommodating the seeds. The top of the storage box 20 is provided with a feeding port 22, so as to facilitate the addition of seeds, so that the storage box 20 can store a certain amount of seeds to facilitate the seeding in the land. The bottom of the storage box 20 is designed as a funnel structure, which is helpful for the smooth entry of the seeds into the seed distribution disc 30. Moreover, since the seed distribution disc 30 is located below the storage box 20 and is detachably installed on the vehicle body 10, when the seeding work is needed, the seed distribution disc 30 and the storage box 20 can be installed on the vehicle body 10. In this way, when the vehicle body 10 travels, the seeds in the storage box 20 can flow to the feeding port 32 of the seed distribution disc 30 under the action of gravity through the funnel structure at the bottom, and after being uniformly distributed by the seed distribution disc 30, the seeds can be dropped into the corresponding furrow through the discharging port 33 of the seed distribution disc 30. When the seeding work is not needed, the seed distribution disc 30 and the storage box 20 can be detached from the vehicle body 10. On the one hand, not only can the seed distribution disc 30 and the storage box 20 be conveniently cleaned and maintained, which is helpful for removing the residual seeds, soil and other impurities, so as to prevent the device from being corroded or blocked to ensure that the device is in the best state for use next time, but also potential problems can be found and solved in time, such as replacement of worn parts, so as to prolong the service life of the entire seeding device. On the other hand, the detached seeding device has a small size and is convenient to store. In addition, when the site is transferred or transported over a long distance, the detached seeding device is easier to carry, which can reduce the transportation difficulty and cost. The automatic seeding device provided by the present disclosure can realize the automation of the seeding process, and can efficiently complete the storage, distribution and final seeding of the seeds into the soil, can reduce the demand for manpower, and can improve the efficiency of agricultural production.

[0056] Optionally, the vehicle body 10 in the present disclosure can be installed on a towing device (such as a tractor). When the work needs to be carried out on a large area or multiple scattered lands, the seeding device can be installed on the towing device, which can conveniently and quickly move to different fields for seeding work, and can reduce the preparation time and labor cost.

[0057] Since the hardness of different soils has a significant impact on trenching operation, optionally, a weight block can be provided on the side of the vehicle body 10 close to the trenching mechanism 40. The weight block can increase the overall weight of the device, which can help to improve the stability of the vehicle body 10 and maintain the consistency of the trenching depth. Specifically, in soft soil, the pressure of the weight block can be reduced to prevent over-trenching or unnecessary soil disturbance. In hard soil, the pressure of the weight block can be increased to ensure that the trenching mechanism 40 smoothly cuts into the soil to form a suitable trench depth.

[0058] As an embodiment, as shown in Figures 1 to 2 The vehicle body 10 includes a vehicle body 11, a first support frame 12 and a second support frame 13, the first support frame 12 and the second support frame 13 are oppositely arranged and connected with the vehicle body 11, the seed dividing disc 30 is located between the first support frame 12 and the second support frame 13, the first support frame 12 is formed with a recess 121 with an upward opening, the second support frame 13 is provided with a snap ring 131 opposite to the recess 121, one end of the seed dividing disc 30 is provided with a first rotating shaft 50, the other end of the seed dividing disc 30 is provided with a second rotating shaft 51, the first rotating shaft 50 is inserted into the snap ring 131, and the second rotating shaft 51 is accommodated in the recess 121.

[0059] In this way, the seed dividing disc 30 can be moved horizontally towards the first support frame 12, so that the first rotating shaft 50 of the seed dividing disc 30 is separated from the snap ring 131 on the second support frame 13, thereby achieving the purpose of quickly disassembling the seed dividing disc 30 from the first support frame 12 and the second support frame 13.

[0060] As an embodiment, as shown in Figures 1 to 2 The vehicle body 11 includes a chassis 111, and a first side frame 112 and a second side frame 113 oppositely arranged on the chassis 111, the two ends of the first support frame 12 are respectively detachably connected to the first end of the first side frame 112 and the first end of the second side frame 113, and the two ends of the second support frame 13 are connected to the second end of the first side frame 112 and the second end of the second side frame 113 respectively, the first side frame 112 and the second side frame 113 have a taking and placing space therebetween, and the taking and placing space is arranged to allow the seed dividing disc 30 to pass through when the first support frame 12 is removed from the first side frame 112 and the second side frame 113.

[0061] When the first support frame 12 is removed from the first side frame 112 and the second side frame 113, the taking and placing opening between the first side frame 112 and the second side frame 113 is in an open state without the obstruction of the first support frame 12, so that the seed dividing disc 30 can be taken out from the taking and placing opening in a direction away from the second support frame 13, thereby achieving the purpose of facilitating the taking out of the seed dividing disc 30.

[0062] In order to realize the quick installation and disassembly of the first support frame 12 on the first side frame 112 and the second side frame 113, as an embodiment, as shown in Figures 1 to 2 the first end of the first side frame 112 is formed with a first clamping groove 1121, the first end of the second side frame 113 is formed with a second clamping groove 1131, the openings of the first clamping groove 1121 and the second clamping groove 1131 are both configured as U-shaped structures, and the two ends of the first support frame 12 are respectively arranged in the first clamping groove 1121 and the second clamping groove 1131.

[0063] As an embodiment, as shown in Figure 1 , Figure 2 and Figure 4 the vehicle body 10 further comprises a mounting rod 14, the ditching mechanism 40 comprises a connecting rod 41, two ditching blades 42, two clamping plates 43, a first adjusting bolt 44 and a second adjusting bolt 45, the mounting rod 14 is arranged on the first side frame 112, the connecting rod 41 is arranged vertically, the two ditching blades 42 are respectively connected to the lower ends of the connecting rod 41 and are arranged at an acute angle, the first adjusting bolt 44 and the second adjusting bolt 45 are both configured as U-shaped structures, the first adjusting bolt 44 and the second adjusting bolt 45 are arranged vertically and are sleeved on the connecting rod 41, the two sides of the mounting rod 14 are provided with two symmetrical clamping plates 43, the bolt rod of the first adjusting bolt 44 is used to pass through the upper ends of the two clamping plates 43 in sequence to be connected with a first nut 46, and the bolt rod of the second adjusting bolt 45 is used to pass through the lower ends of the two clamping plates 43 in sequence to be connected with a second nut 47.

[0064] Among them, the adjusting bolt (the first adjusting bolt 44 and the second adjusting bolt 45) with U-shaped structure not only facilitates quick adjustment, but also can provide sufficient fastening force to ensure that the ditching blade 42 remains stable during work, so as to ensure the accuracy and uniformity of ditching.

[0065] Among them, by arranging the first adjusting bolt 44 and the second adjusting bolt 45, the height and angle of the ditching mechanism 40 can be conveniently adjusted to adapt to different soil conditions and seeding requirements.

[0066] As an embodiment, as shown in Figures 1 to 3As shown, the seed distribution tray 30 comprises two baffles 34, a first side plate 35, a second side plate 36, and a seed distribution wheel 37, and the automatic seeding device further comprises a rotating shaft 60 and a driving member 70, the first side plate 35 and the second side plate 36 are connected between the two baffles 34, the two baffles 34, the first side plate 35 and the second side plate 36 define a cavity 31, a gap is formed between the upper end of the first side plate 35 and the upper end of the second side plate 36 to form a feeding port 32 of the seed distribution tray 30, a gap is formed between the lower end of the first side plate 35 and the lower end of the second side plate 36 to form a discharging port 33 of the seed distribution tray 30, the seed distribution wheel 37 is located in the cavity 31 to separate a plurality of distribution chambers 374, and the driving member 70 is arranged to drive the seed distribution wheel 37 to rotate in the cavity 31 through the rotating shaft 60, so that one of the plurality of distribution chambers 374 can communicate with the feeding port 32 and another of the plurality of distribution chambers 374 can communicate with the discharging port 33.

[0067] When the seeding device is in operation, the seed material enters the cavity 31 of the seed distribution tray 30 from the storage box 20 through the feeding port 32. As the driving member 70 can drive the seed distribution wheel 37 to rotate through the rotating shaft 60, each distribution chamber 374 can be loaded with seed material through the feeding port 32 in turn, and then continue to rotate to release the seed material at the discharging port 33. Since only one distribution chamber 374 can communicate with the feeding port 32 or the discharging port 33 at a time, the seed material can be accurately distributed in a predetermined amount (the capacity of the distribution chamber 374) and interval, thereby facilitating to ensure the consistency of the seeding density.

[0068] As an embodiment, as shown in Figure 3 As shown, the first side plate 35 and the second side plate 36 are both configured as first arc-shaped plates, and the two baffles 34 are both configured as circular plates, and the two sides of the arc-shaped plates are fitted with the edges of the circular plates.

[0069] Since the first side plate 35 and the second side plate 36 are both configured as first arc-shaped plates, the two side plates both have a certain curvature, which is helpful to form a circular or partially circular cavity 31, and is conducive to the flow and distribution of the seed material in the cavity 31.

[0070] As shown in

[0071] As shown in Figure 1 and Figure 2 As shown, the top of the circular plate is formed with a notch for avoiding the storage box 20.

[0072] As one embodiment of the seeding wheel 37, as shown in Figure 3, the seeding wheel 37 includes a connecting plate 371 and multiple partition sections 372. Each partition section 372 is constructed as a second arc-shaped plate. Multiple arc-shaped notches 373 are formed on the connecting plate 371. The multiple arc-shaped notches 373 are spaced apart along the circumference of the connecting plate 371. Each arc-shaped notch 373 is respectively provided with a partition section 372. The two baffles 34, the inner wall of the partition section 372, and the first side plate 35 and / or the second side plate 36 together define the distribution chamber 374. The rotating shaft 60 passes through the connecting plate 371, and the two ends of the rotating shaft 60 are rotatably connected to the two baffles 34. One end of the rotating shaft 60 protrudes from the seeding disc 30 and is connected to the driving end of the driving member 70. The width of the first side plate 35 and the width of the second side plate 36 are the same as the width of the partition section 372.

[0073] Since the width of the first side plate 35, the width of the second side plate 36, and the width of the partition section 372 are the same, it can effectively prevent the seed material from leaking or misaligning during the rotation inside the seed distribution tray 30. This helps to ensure that the space size of each distribution chamber 374 is consistent, so that the amount of seed material distributed each time is the same, thereby improving the accuracy of sowing.

[0074] To reduce severe wear on the inner wall (first side plate 35 and second side plate 36) of the seeding disc 30 during rotation at the connection point of two adjacent partition sections 372, such as... Figure 5 As shown, optionally, a slide bar 90 can be provided at the connection between two adjacent partition sections 372. The slide bar 90 has a semi-cylindrical structure. In this way, the slide bar 90 can play a role in smooth transition, which can prevent the sharp edges of the connection between the partition sections 372 from directly contacting the inner wall of the seeding disk 30. This not only reduces frictional resistance, but also avoids severe wear caused by rotation.

[0075] As one implementation method, such as Figures 1 to 2 As shown, the vehicle body 10 also includes a vehicle body 11 and wheels 114. The wheels 114 are located at the bottom of the vehicle body 11, and a mounting plate 115 is located at the top of the vehicle body 11. The mounting plate 115 is used to mount the drive component 70.

[0076] The wheels 114 allow the entire seeding device to be transported to a designated location, and also facilitate easy movement of the seeding device on the land to adapt to different terrain conditions.

[0077] Optionally, such as Figure 2 As shown, the drive component 70 can be a motor.

[0078] As one implementation method, such as Figures 1 to 2As shown, the automatic seeding device further comprises a flow guide cover 80, which is arranged at the discharge port 33 and is configured in a structure of decreasing cross section from top to bottom.

[0079] Through the flow guide cover 80, the seed material discharged from the discharge port 33 can be accurately guided into the trench opened by the trenching mechanism 40, the possibility of deviation from the predetermined path can be reduced, and the seeding accuracy can be improved. In addition, it is also helpful to concentrate the flow direction of the seed material, and can avoid the scattering phenomenon of the seed material after leaving the discharge port 33, so as to ensure the uniform distribution of the seed material.

[0080] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments.
