Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a seeding spacing adjustment device for agricultural planting. Background Technology
[0002] Sowing, one of the crop cultivation measures, is the operation of sowing materials into the soil layer at a certain depth and in a certain quantity and manner at the appropriate time. Whether the sowing is appropriate or not directly affects the growth, development and yield of crops. In order to improve the sowing quality, it is necessary to control the sowing spacing of seeds. In the existing technology, the sowing spacing of seeds in seeders is mostly adjusted by replacing the seed trays. Different seed trays have different spacing between the grooves that hold seeds, so the sowing spacing can be adjusted. However, the seed trays of existing devices are mostly fixed by bolts. When replacing them, multiple bolts need to be disassembled and reinstalled, which is cumbersome and has low replacement efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a seeding spacing adjustment device for agricultural planting, which allows growers to quickly adjust and replace the seeding tray, thereby improving the overall seeding efficiency. The device is also simple and convenient to operate.
[0004] The specific technical solution adopted by this utility model is as follows:
[0005] An agricultural planting spacing adjustment device includes a mounting box, the upper surface of which is fixedly connected to a connecting hose, the upper end of which is fixedly connected to the bottom surface of a connecting plate, and the lower end of which corresponds to a seed metering mechanism, which is located inside the mounting box.
[0006] A flow guide plate is provided below the seeding mechanism, and the flow guide plate is fixedly installed inside the bottom surface of the mounting box.
[0007] The seeding mechanism includes two connecting cylinders, which are rotatably connected to the left and right sides of the mounting box via sealed bearings.
[0008] A fixing plate is fixedly provided on the outer side of the opposite ends of the two connecting cylinders, and each fixing plate has multiple connecting holes.
[0009] Each of the connecting cylinders has two sliding grooves on its inner wall, and the four sliding grooves are slidably connected to one end of the four sliding plates respectively.
[0010] The other ends of the four sliding plates are fixedly connected to the outer side of the rotating shaft, and the two ends of the rotating shaft are respectively sleeved with two connecting cylinders.
[0011] Multiple seeding discs are fixedly installed on the rotating shaft, and each seeding disc has a set of storage slots on its side.
[0012] The number of storage slots in each of the multiple sets is different, and the top of the rightmost seeding disc overlaps with the bottom of the connecting hose.
[0013] The right side of the rightmost seeding disc overlaps with the rear end of the left side of the positioning plate. The front end of the positioning plate is rotatably connected to the inner side of the mounting box via a hinge seat. The side of the positioning plate is fixedly connected to the rear end of two return springs, and the front ends of the two return springs are fixedly connected to the inner side of the mounting box.
[0014] The rotating shaft is also rotatably connected to the rear end of the connecting frame via a bearing. The front end of the connecting frame is provided with a screw hole for threaded connection with the screw rod. The left end optical shaft of the screw rod is rotatably connected to the left side of the mounting box via a sealed bearing. A limit plate is fixedly provided at the right end of the screw rod.
[0015] The upper surface of the mounting box is fixedly connected to the bottom ends of two mounting bases on the left and right sides respectively. The front and rear sides of the connecting plate are fixedly connected to the opposite ends of two mounting bases. Multiple mounting holes are provided at the upper ends of the two mounting bases and the opposite ends of the two mounting bases. The mounting box is a transparent plastic box.
[0016] The technical effects achieved by this utility model are as follows:
[0017] This invention features a seed metering mechanism within the installation box that contacts a connecting hose. During sowing, the connecting hose delivers seeds in a measured quantity, allowing them to fall into the storage tank.

Detailed Implementation
[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0026] like Figure 1-5 As shown, an agricultural planting spacing adjustment device includes a mounting box 1. The upper surface of the mounting box 1 is fixedly connected to a connecting hose 5. The upper end of the connecting hose 5 is fixedly connected to the bottom surface of a connecting plate 3. The bottom end of the connecting hose 5 corresponds to a seed metering mechanism 6. The seed metering mechanism 6 is located inside the mounting box 1.
[0027] A guide plate 7 is provided below the seeding mechanism 6, and the guide plate 7 is fixedly installed inside the bottom surface of the mounting box 1.
[0028] Furthermore, the seeding mechanism 6 includes two connecting cylinders 61, which are rotatably connected to the left and right sides of the mounting box 1 respectively via sealed bearings.
[0029] Furthermore, a fixing plate 610 is fixedly provided on the outer side of the opposite ends of the two connecting cylinders 61, and each fixing plate 610 has multiple connecting holes.
[0030] Furthermore, each connecting cylinder 61 has two sliding grooves 612 on its inner wall, and the four sliding grooves 612 are slidably connected to one end of the four sliding plates 613 respectively.
[0031] Furthermore, the other ends of the four sliding plates 613 are fixedly connected to the outer side of the rotating shaft 611. The two ends of the rotating shaft 611 are respectively sleeved with two connecting cylinders 61. By providing a sliding groove 612 inside the connecting cylinder 61 and providing a sliding plate 613 connected to the sliding groove 612 on the outside of the rotating shaft 611, the rotating shaft 611 and the seeding disc 63 are driven to rotate by the connection between the sliding groove 612 and the sliding plate 613 when the connecting cylinder 61 rotates.
[0032] Furthermore, multiple seeding discs 63 are fixedly installed on the rotating shaft 611, and each seeding disc 63 has a set of storage slots 64 on its side.
[0033] Furthermore, the number of storage slots 64 is different for each group, and the top of the rightmost seeding tray 63 overlaps with the bottom of the connecting hose 5.
[0034] Furthermore, the right side of the rightmost seeding disc 63 overlaps with the rear end of the left side of the positioning plate 65. The front end of the positioning plate 65 is rotatably connected to the inner side of the mounting box 1 via a hinge seat. The sides of the positioning plate 65 are fixedly connected to the rear ends of two return springs 66, and the front ends of the two return springs 66 are fixedly connected to the inner side of the mounting box 1. By setting the positioning plate 65 in the mounting box 1 to contact the seeding disc 63, and setting the return springs 66 to connect with the positioning plate 65, when the seeding disc 63 in contact with the positioning plate 65 moves, it pushes the positioning plate 65 to rotate. When the positioning plate 65 is between the two seeding discs 63, the elastic force of the return springs 66 drives the positioning plate 65 to return to its original position. When the side of the next seeding disc 63 moves to contact the positioning plate 65, the seeding disc 63 and the connecting hose 5 are vertically aligned. Thus, the positioning plate 65 is used to assist the user in judging the corresponding state of the seeding disc 63 and the connecting hose 5.
[0035] Furthermore, the rotating shaft 611 is rotatably connected to the rear end of the connecting frame 62 via a bearing. The front end of the connecting frame 62 is provided with a screw hole 69 and threadedly connected to the screw 68. The optical shaft at the left end of the screw 68 is rotatably connected to the left side of the mounting box 1 via a sealed bearing. A limit plate 67 is fixedly provided at the right end of the screw 68. During sowing, the user can adjust the position of the seeding plate 63 according to the planting spacing requirements so that the corresponding seeding plate 63 contacts the connecting hose 5. At this time, the user can rotate the screw 68 and use the screw hole 69 to drive the connecting frame 62, the rotating shaft 611 and the seeding plate 63 to move left and right. Then, the sowing spacing can be adjusted by using the storage slots 64 with different spacings on the multiple seeding plates 63, which effectively improves the operating efficiency and eliminates the need for the user to disassemble the device.
[0036] Furthermore, the upper surface of the mounting box 1 is fixedly connected to the bottom ends of the two mounting bases 2 on the left and right sides respectively, and the front and rear sides of the connecting plate 3 are fixedly connected to the opposite ends of the two mounting bases 4 respectively. Multiple mounting holes are provided at the upper ends of the two mounting bases 2 and the opposite ends of the two mounting bases 4. The mounting box 1 is a transparent plastic box.
[0037] The working principle of this utility model is as follows: When installing this device, the mounting box 1, the connecting plate 3 and the seeder can be installed and connected by the mounting base 1 2 and the mounting base 2 4, and the connecting plate 3 is aligned with the feed port of the seeder. At the same time, the coupling and the end of the connecting cylinder 61 are connected by the fixing plate 610 so that the seed metering mechanism 6 of the two adjacent devices are connected by transmission. The connecting cylinder 61 of the end device is connected to the power source by means of the coupling.
[0038] During sowing, the user can adjust the position of the seeding disc 63 according to the planting spacing requirements so that the corresponding seeding disc 63 contacts the connecting hose 5. At this time, the user can rotate the screw 68 to drive the connecting frame 62, the rotating shaft 611, and the seeding disc 63 to move left and right through the screw hole 69. When the seeding disc 63 in contact with the positioning plate 65 moves, it pushes the positioning plate 65 to rotate. When the positioning plate 65 is between two seeding discs 63, the spring force of the return spring 66 drives the positioning plate 65 to return to its original position. When the next seeding disc 63 moves to the side and contacts the positioning plate... When the seeding disc 63 and the connecting hose 5 are in contact, the screw 68 can be stopped. During sowing, the seeds stored in the seeder fall into the connecting hose 5 through the connecting disc 3, and the seeds fall into the storage tank 64 in the seeding disc 63 through the bottom of the connecting hose 5. During sowing, the power source drives the connecting cylinder 61 to rotate. When the connecting cylinder 61 rotates, it drives the rotating shaft 611 and the seeding disc 63 to rotate through the sliding groove 612 and the sliding plate 613. When the seeding disc 63 rotates, the seeds in the storage tank 64 fall into the guide plate 7 and are discharged.
[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
