Description

Technical Field

[0001] This utility model relates to the field of composite seeders, specifically to a vegetable planting composite seeder that applies seeds and fertilizer simultaneously. Background Technology

[0002] In the modern agricultural production system, vegetable planting is a key industry for ensuring the supply of food for people's livelihood. Its planting efficiency and quality directly affect agricultural economic benefits and market supply stability. With the acceleration of agricultural modernization, corresponding mechanized planting equipment, such as common seed planters, are usually used when sowing.

[0003] This type of seed planter can move along the field and, with the corresponding hopper, unloading pipe and unloading valve, can move along the corresponding planting ditch by opening the valve to carry out the sowing operation.

[0004] For example, the invention patent with authorization announcement number CN109104950A discloses a deep tillage seeder, including a frame and a seed and fertilizer box, a furrow opener, and a pressing roller mounted on the frame. The frame is equipped with a scraper blade connected to the pressing roller, which cleans the soil from the outer surface of the roller. The scraper blade is inserted into the frame, which has corresponding slots. One end of the scraper blade extends out of the slot and contacts the pressing roller. The scraper blade is fixed to the frame with bolts. This simple insertion and removal operation allows for easy cleaning of foreign matter adhering to the scraper blade, thus avoiding affecting its cleaning effect on the pressing roller.

[0005] While this technical solution has the advantage of easily cleaning foreign objects attached to the scraper, thus avoiding affecting its cleaning effect on the pressing roller, most current seed planters can only perform seed sowing alone and cannot simultaneously sow fertilizer into the field, affecting planting efficiency. Adding a subsequent fertilization step makes the entire planting process cumbersome and affects the effectiveness. Some seed planters, although capable of simultaneously sowing seeds and fertilizer, directly place the seeds and fertilizer together without pre-covering the seeds, causing direct contact and affecting germination rates. Therefore, we propose a combined seed and fertilizer planter for vegetable cultivation. Utility Model Content

[0006] The purpose of this invention is to provide a vegetable planting composite seeder that simultaneously applies seeds and fertilizer, in order to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vegetable planting composite seeder that simultaneously applies seeds and fertilizer includes a large arm plate mounted on a seeder. The large arm plate has two symmetrical through holes on the left and right sides, and two symmetrical feed cylinders on the left and right sides. A conical cylinder extending through the through holes is fixedly installed at the bottom end of each feed cylinder, and a discharge pipe is fixedly installed at the bottom end of each conical cylinder. A discharge valve is fixedly installed on the discharge pipe. The feed cylinders and the large arm plate are connected by multiple springs. A central connecting plate is fixedly installed between the two feed cylinders, and a vibration motor is fixedly installed on the central connecting plate. A drive motor is also fixedly installed on the large arm plate, located between the two feed cylinders. A vertically oriented long shaft is fixedly installed at the end of the output shaft of the drive motor, and multiple arc-shaped soil-removing blades arranged in a ring at equal intervals are fixedly installed on the bottom end of the long shaft.

[0009] Preferably, the vertical distance between the outer surface of the conical cylinder and the wall of the through hole is between 5cm and 12cm, and the conical cylinder is funnel-shaped.

[0010] Preferably, the plane containing the inner wall of the conical cylinder is inclined downward at 45 to 60 degrees, and the cross-section of the arc-shaped soil-removing blade is arc-shaped.

[0011] Preferably, a plurality of bottom support plates are fixedly installed on the bottom cylinder of the material cylinder, the bottom end of the spring is fixedly installed on the upper arm plate, and the top end of the spring is fixedly installed on the bottom surface of the bottom support plate;

[0012] This feature utilizes spring support to enhance the vibration effect of the vibrating motor, making it easier for seeds and fertilizer to fall out of the feed cylinder.

[0013] Preferably, two sets of symmetrical guide rods are fixedly installed on the upper surface of the boom plate, and multiple guide plates are fixedly installed on the cylinder body of the material cylinder. The guide plates are sleeved on the guide rods and slidably connected to the guide rods.

[0014] This setting serves to vertically guide the vibration process of the barrel, preventing the barrel from shifting left or right.

[0015] Preferably, each group of multiple guide rods is arranged in a ring with equal spacing, and the size of the guide plate is adapted to the size of the guide rod.

[0016] Preferably, one of the feed cylinders is used to hold seeds, and the other feed cylinder is used to hold fertilizer, with a feed hopper fixedly installed on the top of each feed cylinder.

[0017] Preferably, a top cover is fitted onto the top cylinder of the feed hopper, and two symmetrical handles are fixedly installed on the top surface of the top cover.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model sets up two symmetrical material cylinders on the left and right sides, which are used to hold seeds and fertilizer respectively. With the help of the unloading pipe and unloading valve, it realizes the function of simultaneous application of seeds and fertilizer, thereby improving planting efficiency and simplifying the planting process.

[0020] 2. This utility model improves the vibration effect by using a spring to support the material cylinder and cooperating with a vibration motor on the central connecting plate, so that seeds and fertilizers can be discharged from the material cylinder more smoothly, solving the problem of easy material blockage and ensuring the continuity and uniformity of sowing and fertilization.

[0021] 3. This utility model utilizes the guide rod on the boom plate to slide and connect with the guide plate on the material cylinder, which plays a vertical guiding role in the vibration process of the material cylinder. At the same time, the arc-shaped soil-dispensing blades can effectively displace the soil to cover the sown seeds, avoid displacement of the material cylinder, enhance adaptability to different soil conditions, provide a good soil environment for seeds and fertilizers, prevent fertilizers from directly contacting seeds and affecting germination rate, and improve sowing quality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-3 This utility model provides a technical solution: a vegetable planting composite seeder that applies seeds and fertilizer simultaneously, including a boom plate 1 installed on a seeder vehicle. The boom plate 1 can be raised or lowered by a hydraulic cylinder on the seeder vehicle. The boom plate 1 is driven by a hydraulic cylinder, which is a conventional technology and will not be described in detail here.

[0032] Specifically, the boom plate 1 has two symmetrical through holes 10 on the left and right sides, and two symmetrical material cylinders 2 on the left and right sides. One material cylinder 2 is used to hold seeds, and the other material cylinder 2 is used to hold fertilizer. A feeding hopper 25 is fixedly installed on the top of the material cylinder 2 for feeding. A conical cylinder 20 is fixedly installed at the bottom of the material cylinder 2, which passes through the through holes 10. A discharge pipe 21 is fixedly installed at the bottom of the conical cylinder 20, and a discharge valve 22 is fixedly installed on the discharge pipe 21. With the discharge pipe 21 and discharge valve 22 at the bottom, seeds and fertilizers can be stored independently and applied as needed, realizing simultaneous application of seeds and fertilizers, improving planting efficiency and simplifying the planting process.

[0033] like Figure 1 As shown, the material cylinder 2 and the boom plate 1 are connected by multiple springs 12. A central connecting plate 3 is fixedly installed between the two material cylinders 2. A vibration motor 30 is fixedly installed on the central connecting plate 3. The vibration effect is significantly improved by using the springs 12 to support and cooperate with the vibration motor 30, so that the seeds and fertilizers can be discharged more smoothly from the material cylinder 2 through the conical cylinder 20 and the discharge pipe 21, effectively preventing material blockage.

[0034] like Figure 1 and Figure 2 As shown, a drive motor 4 is also fixedly installed on the large arm plate 1. The drive motor 4 is located between the two material cylinders 2. A vertically arranged long shaft 40 is fixedly installed at the end of the output shaft of the drive motor 4. Multiple arc-shaped soil-dispensing blades 41 arranged in a ring at equal intervals are fixedly installed on the bottom rod of the long shaft 40. The cross-section of the arc-shaped soil-dispensing blades 41 is arc-shaped, which ensures that when the seeds fall in front, the drive motor 4 drives the long shaft 40 and the arc-shaped soil-dispensing blades 41 to rotate, which can turn the surrounding soil over to cover the seeds before the fertilizer falls. This can prevent the fertilizer from directly contacting the seeds and affecting the germination rate of the seeds.

[0035] It is worth noting that during the actual sowing operation, a furrow opener is generally used to open corresponding furrows in the soil. The seeds then fall into the furrows, and the curved soil-removing blades 41 are used to cover them with a certain thickness of soil. As the fertilizer falls, the covered soil can prevent the seeds from coming into direct contact with the fertilizer, thus avoiding the situation of burning the seedlings.

[0036] In addition, the vertical distance between the outer surface of the conical cylinder 20 and the wall of the through hole 10 is between 5cm and 12cm. The conical cylinder 20 is funnel-shaped, and the plane of the inner wall of the conical cylinder 20 is inclined downward at 45 degrees to 60 degrees, so that the material can slide down into the unloading pipe 21 more quickly and smoothly in the conical cylinder 20, further ensuring the smoothness of seed and fertilizer application.

[0037] like Figure 1 As shown, multiple bottom support plates 24 are fixedly installed on the bottom cylinder of the material cylinder 2. The bottom end of the spring 12 is fixedly installed on the upper arm plate 1, and the top end of the spring 12 is fixedly installed on the bottom surface of the bottom support plate 24. With the support of the spring 12, the vibration effect of the vibration motor 30 can be improved, making the seeds and fertilizer fall down the material cylinder 2 more smoothly.

[0038] like Figure 1 As shown, two sets of symmetrical guide rods 11 are fixedly installed on the upper surface of the boom plate 1. Multiple guide plates 23 are fixedly installed on the cylinder body of the material cylinder 2. The guide plates 23 are sleeved on the guide rods 11 and slidably connected to the guide rods 11, which plays a vertical guiding role in the vibration process of the material cylinder 2, preventing the material cylinder 2 from shifting left and right during vibration, and ensuring the accuracy of the seed and fertilizer placement position.

[0039] It is worth noting that each group of multiple guide rods 11 are arranged in a ring with equal spacing, and the size of the guide plate 23 is matched with the size of the guide rods 11, so as to improve the guiding effect.

[0040] like Figure 1 and Figure 3 As shown, a top cover 26 is fitted onto the top cylinder of the feed hopper 25. Two symmetrical handles 261 are fixedly installed on the top surface of the top cover 26. When the top cover 26 is closed, it can provide waterproof and dustproof protection.

[0041] Finally, it should be noted that the vibration motor 30 and drive motor 4 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0042] When using the vegetable planting composite seeder that simultaneously applies seeds and fertilizer, the hydraulic cylinder on the seeder first drives the boom plate 1 to descend to a suitable working height, and then pours the seeds and fertilizer into the corresponding feed cylinders 2 through the feed hopper 25. After that, the top cover 26 is put on to prevent dust and water.

[0043] After the ditcher opens the furrows in the soil, it moves in the field with the seeder and opens the unloading valve 22. The seeds fall from one of the feed cylinders 2 through the conical cylinder 20 and the unloading pipe 21 into the furrow. At this time, the drive motor 4 drives the long shaft 40 and the arc-shaped soil-removing blades 41 to rotate, turning the surrounding soil over and covering the seeds. Then, the fertilizer in the other feed cylinder 2 falls onto the covering soil through the same path, avoiding direct contact between the seeds and the fertilizer.

[0044] Throughout the sowing process, the vibrating motor 30 works continuously, and the spring 12 enhances the vibration effect, allowing the seeds and fertilizer to be discharged smoothly from the feed cylinder 2. At the same time, the sliding connection between the guide rod 11 and the guide plate 23 ensures that the feed cylinder 2 moves vertically when vibrating, ensuring accurate seed and fertilizer placement.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
