Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and in particular relates to a multi-chamber seed drill with adjustable feeding amount. Background Art

[0002] The seeder includes a shell with upper and lower openings respectively, the upper opening is used to receive materials from the material box, and the lower opening is used to discharge materials. A seed wheel is rotatably connected inside the seeder, and seeds are sown from the lower opening through the rotation of the seed wheel. In order to achieve a good sowing effect, the structure of the seed wheel varies according to different crop seeds. There are small-particle seed wheels for sowing small seeds, large-particle seed wheels for sowing large seeds, and round-groove seed wheels for sowing specific crops, such as corn seeds. For users, if they need to plant different crops, they need to purchase multiple seeders, which is costly. Therefore, multi-chamber seeders are widely used.

[0003] Traditional seeders use a brush and a seed wheel to sow seeds. In actual use, if the amount of seeds fed is large, the amount of seeds discharged is large, and if the amount of seeds fed is small, the amount of seeds discharged is small. Although the brush can adapt to the amount of seeds discharged, the brush is not stable. The sowing amount is relatively stable when a new brush is first used, but with long-term use, fatigue will occur and the sowing amount will be difficult to control.

[0004] Patent CN202322646504.8 provides a multi-chamber seed metering device, which replaces the soft brush with a hard tongue plate to form a material trough. The tongue plate will not produce fatigue deformation, and a guide plate is arranged above the seeding wheel. The guide plate is used to guide the seeds onto the tongue plate, and the seeds on the tongue plate are picked up to the discharge port as the seeding wheel rotates. The above patent sets the structure of the guide plate and the tongue plate. Although it avoids the defects of the brush, it also lacks the function of adjusting the discharge amount and cannot adapt to sowing operations in various environments.

[0005] Therefore, the technical problem to be solved by the utility model is that the existing seeders either have a device for adjusting the sowing amount that is not durable, or do not have the function of adjusting the sowing amount that is not suitable for sowing operations in various environments.

[0023] The following will be combined with the drawings in 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 implementation of the utility model, not all of the implementation. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, the utility model provides a multi-chamber seeder with adjustable feeding amount, including a shell 1, wherein the shell 1 is divided into at least two chambers by a partition 2, the partition 2 is fixedly connected to the shell 1, and a pluggable baffle 4 is arranged on the top of each chamber, and a seeding wheel is rotatably connected in each chamber, and the seeding wheels in adjacent chambers are snap-fitted and fixed together to form a seeding wheel group, and first rotating shafts are respectively arranged on both sides of the seeding wheel group, and the first rotating shafts are rotatably connected to the shell 1, and the shell 1 limits the two sides of the seeding wheel group.

[0025] The shell 1 is provided with an adjusting device for controlling the material discharge amount of the chamber, and the adjusting device includes a moon plate 6. A rotating shaft 9 is provided at the inner end of the moon plate 6, and one end of the rotating shaft 9 extends out of the outside of the shell 1. The part extending out of the outside of the shell 1 is connected to a rotating handle 7, and the rotating handle 7 is coaxially fixedly connected to the moon plate 6 through the rotating shaft 9.

[0026] The utility model provides a multi-chamber seeder with adjustable feeding amount, which is provided with a feeding amount adjusting device. By turning a rotating handle, a moon plate is driven to move synchronously to adjust the gap between the moon plate and a seeding wheel group, thereby adjusting the feeding amount of the chamber to meet the sowing requirements of multiple regions. The utility model has a wide application, and the adjusting device is durable and not easy to be damaged.

[0027] like Figure 1 and Figure 3 As shown, a baffle 4 for opening or closing the feed port of the chamber is provided in the shell 1. The baffle 4 is provided at the feed port of the chamber. When the baffle 4 is pulled out, the feed port of the chamber can be blocked. When the baffle 4 is inserted, the feed port of the chamber can be opened.

[0028] like Figure 3 As shown, a guide plate 5 for guiding the material at the feed port of the chamber to the seeding wheel group is arranged in the shell 1, and the guide plate 5 is fixed above the seeding wheel group.

[0029] like Figure 3 As shown, a moon plate 6 for guiding the material on the seeding wheel group to the discharge port is arranged in the shell 1, and the moon plate 6 is arranged below the seeding wheel group.

[0030] like Figure 1 and Figure 4 As shown, one end of the rotary handle 7 is rotatably connected to the housing 1, and a second protrusion 71 is fixed on the surface of the other end opposite to the housing 1; the second protrusion 71 is used to achieve fixation after adjustment.

[0031] like Figure 1 As shown, at least one first protrusion 11 is fixed on the outer surface of the shell 1, and a gap is set between each two adjacent first protrusions 11, and the size of the gap matches the size of the second protrusion 71, so that the second protrusion 71 can be embedded in the gap; each gap forms a gear, and by turning the rotating handle 7, the second protrusion 71 is stuck in different gaps to achieve adjustment of different gears.

[0032] The first protrusion 11 is distributed in an arc shape, and the arc shape matches the arc shape of the rotating handle 7 at one end of which the second protrusion 71 is provided.

[0033] like Figure 1 and Figure 4 As shown, a limiting strip 8 for limiting the rotating handle 7 is fixed on the outer side surface of the housing 1 , and both ends of the limiting strip 8 are fixed on the housing 1 .

[0034] Specifically, the limiting effect of the limiting bar 8 on the rotating handle 7 includes two aspects. On the one hand, the limiting bar 8 limits the rotation range of the rotating handle 7 along the direction parallel to the outer side surface of the shell 1, so that the rotating handle 7 can only rotate within the area restricted by the limiting bar 8; on the other hand, the limiting bar 8 limits the distance between the rotating handle 7 and the outer side surface of the shell 1 along the direction perpendicular to the outer side surface of the shell 1.

[0035] Since the seeder is constantly vibrating during operation, simply by clamping the second protrusion 71 on the rotating handle 7 between two adjacent first protrusions 11, the vibration of the machine will cause the coordination effect of the second protrusion 71 and the first protrusion 11 to gradually deteriorate. In extreme cases, the second protrusion 71 may even fall out from between the two adjacent first protrusions 11. At this time, the rotating handle 7 will rotate downward by itself under the action of gravity, driving the moon plate 6 to move downward synchronously, thereby increasing the gap between the moon plate 6 and the seeding wheel group and increasing the amount of material discharged, which does not meet the required amount of material discharged in actual work. Therefore, a limit strip 8 is provided to solve this problem.

[0036] The limiting strip 8 is made of plastic.

[0037] The utility model is provided with an adjusting device, which can not only adjust the amount of sowing materials according to actual needs, but also when the rotating handle 7 is rotated to the bottom of the limit area, the distance between the moon plate 6 and the seeding wheel group is the largest, and the surplus grain can be cleaned up at this time.

[0038] like Figure 1 and Figure 2 As shown, there are three chambers, namely a left chamber, a right chamber, and a middle chamber. Both the left chamber and the right chamber are provided with a small-particle seed discharging wheel 31, and the middle chamber is provided with a large-particle seed discharging wheel 32. A circular discharging groove 321 is provided on the outer periphery of the large-particle seed discharging wheel 32.

[0039] The width of the left chamber and the right chamber are both 20mm-25mm, preferably 23mm, and the width of the middle chamber is 30mm-35mm, preferably 32mm.

[0040] The utility model is provided with a guide plate 5 and a moon plate 6 structure. When working, seeds enter from the feed port of the chamber, and the guide plate 5 guides them to fall onto the moon plate 6. As the seed wheel rotates, the teeth on the seed wheel pick the seeds to the discharge port, thereby achieving seed sowing.

[0041] like Figure 2 As shown, the discharge port of the left chamber and the discharge port of the right chamber are respectively connected to different discharge ports, and the discharge port of the middle chamber is connected to both discharge ports; specifically, a first discharge port 121 is arranged below the discharge port of the left chamber, a second discharge port 122 is arranged below the discharge port of the right chamber, and the discharge port of the middle chamber is located above between the first discharge port 121 and the second discharge port 122; when the middle chamber is used for sowing, seeds can be sown from both the first discharge port 121 and the second discharge port 122.

[0042] Two small-particle seed chambers are set up. In areas with small sowing amounts, only one side of the chamber can be used for sowing. In areas with large sowing amounts, the chambers on both sides can be used for sowing together to adapt to the differences in sowing amounts in different regions. The application range is wider, two discharge ports are set up, and a double-line sowing method is adopted. There is sufficient sowing area, there are gaps between seeds, the arrangement is more uniform, the germination rate is better, and production and income are increased.

[0043] like Figure 1 , Figure 3 and Figure 5 As shown, the utility model can also adopt another adjustment method, specifically, a notch 61 is provided at the bottom of the moon plate 6, and at least one pin hole is provided on the outer side of the shell 1 corresponding to the arc formed by the rotation of the notch 61, and a hole is provided on the partition 2 corresponding to each pin hole. In actual use, the pin shaft passes through the pin hole, the notch 61 and the hole in sequence along the direction perpendicular to the outer side of the shell 1, and the moon plate 6 is supported by the pin shaft. The position of the moon plate 6 is adjusted by inserting the pin shaft into the pin holes at different positions and the holes corresponding to the selected pin holes, so as to achieve adjustment of different gears.

[0044] The specific working process of the utility model is as follows:

[0045] The material discharge amount of the bin is adjusted according to actual needs. When adjusting, the staff pinches the end of the rotating handle 7 with the second protrusion 71 and lifts it in the direction away from the shell 1. After lifting, within the limiting area of ​​the limiting strip 8, the rotating handle 7 is rotated upward or downward in a direction parallel to the outer side of the shell 1. The rotating handle 7 drives the moon plate 6 to move upward or downward synchronously. The material discharge amount is adjusted by adjusting the size of the gap between the moon plate 6 and the seeding wheel group. After the rotating handle 7 is rotated to the appropriate position, it falls in the direction close to the shell 1, so that the second protrusion 71 on the rotating handle 7 can be stuck between the two adjacent first protrusions 11. Release your hand and the adjustment is completed.

[0046] When the amount of material to be discharged needs to be reduced, the rotary handle 7 is turned upward, and the rotary handle 7 drives the moon plate 6 to move upward synchronously to reduce the gap between the moon plate 6 and the seeding wheel group, thereby reducing the amount of material to be discharged;

[0047] When the amount of material to be discharged needs to be increased, the rotary handle 7 is turned downward, and the rotary handle 7 drives the moon plate 6 to move downward synchronously to increase the gap between the moon plate 6 and the seeding wheel group, thereby increasing the amount of material to be discharged;

[0048] When the rotating handle 7 is turned to the bottom, the remaining food can be cleaned.

[0049] The utility model adds a feeding adjustment device on the basis of the existing seeder structure, and the feeding amount of the seeder can be adjusted during actual use; a feeding port is also added, and double-line sowing is adopted, so that the seeds are arranged more evenly and the emergence rate is higher.

[0050] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
