Description

Technical Field

[0001] This invention relates to the field of peanut planting technology, specifically to a peanut planter fixed-distance planting detection system for remedying missed planting. Background Technology

[0002] Peanut planter with fixed-distance seeding detection for missing seeding refers to a device that monitors the seeding status in real time during the planting process. Once a seed is found to be missing, it is immediately replanted at the accurate location, thus ensuring that peanut seeds are planted precisely at a preset fixed interval.

[0003] In the prior art, Chinese Patent Application No. CN201810195954.0 discloses a reseeding mechanism, including a seed delivery device, a seed conveying device, and a reseeding drive device. The seed conveying device includes a first seed conveying pipe and a second seed conveying pipe fitted together with the first seed conveying pipe, with the inlet of the first seed conveying pipe opposite to the outlet of the seed delivery device. The reseeding drive device includes a crank and a crank rod connected to the crank, the crank rod being axially connected to a connecting rod provided on the second seed conveying pipe. The outlet of the second seed conveying pipe is provided with an openable and closable structure to control whether seeds can be delivered from the lower seed conveying pipe. Through the cooperation of the reseeding drive device, the first seed conveying pipe, the second seed conveying pipe, and the opening and closing mechanism of the second seed conveying pipe, the entire process from seed delivery to reseeding is completed.

[0004] Based on the above information, it can be seen that existing reseeding devices need to be used in conjunction with detection devices, such as using a vision camera to detect whether there are seeds at the sowing location in the field. However, in actual use, there is a lot of dust in the field, and the seeder generates a lot of dust when it is working. The dust adheres to the vision detection device, which affects its detection accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a peanut planter spacing and seeding detection system for remedying missed seeds, so as to solve the problem of dust impact detection mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a peanut planter fixed-distance seeding detection system for seeding loss remediation, comprising seeding pipes arranged at equal intervals and storage boxes fixedly installed above the seeding pipes. The seeding pipes are fixedly installed between the planter body and the planter body via a mounting frame. The seeding pipes correspond one-to-one with the seeding pipes of the planter body. A detection camera corresponding to the position of the seeding pipe is fixedly installed on the lower surface of the mounting frame. An electromagnetic valve for controlling the falling of peanut seeds is installed on the outside of the seeding pipe. A cleaning plate with a sponge structure is provided below the mounting frame. The cleaning plate cleans the dust on the surface of the detection camera by moving left and right through a reciprocating mechanism.

[0007] Preferably, the storage box is connected to the replanting pipeline, and the solenoid valve is controlled in conjunction with the detection camera.

[0008] Preferably, the reciprocating mechanism includes a connecting slider installed inside the mounting frame, and a cleaning plate is fixedly installed at the lower end of the connecting slider.

[0009] Preferably, the connecting slider and the linear slide rail are slidably connected, and the linear slide rail is fixedly installed on the inner surface of the mounting bracket.

[0010] Preferably, a horizontally arranged telescopic cylinder is fixedly installed on the inner side of the mounting bracket, and the front end of the telescopic cylinder is fixedly installed with the connecting slider and drives the connecting slider to move left and right.

[0011] Preferably, a mounting plate is rotatably mounted on the upper surface of the mounting bracket, and a connecting rod is rotatably mounted between the lower surface of the mounting plate and the upper surface of the connecting slider.

[0012] Preferably, the upper surface of the mounting plate is coaxially fixedly mounted with a contact roller that abuts against the outer surface of the storage box, and the outer surface of the contact roller is fixedly mounted with a striking ball with a protruding structure.

[0013] Compared with the prior art, the beneficial effects of this invention are as follows: This peanut planter spacing and seeding detection system for missing seeding adopts a novel structural design, the specific details of which are as follows: During the process of the planter body planting peanuts, a detection camera on the lower surface of the mounting frame photographs and identifies the planted peanut seeds. If a missed seed is detected, an electromagnetic valve is opened to discharge peanuts through a replanting pipe for replanting. A reciprocating mechanism drives a connecting slider to slide on a linear slide rail. During the sliding of the connecting slider, a cleaning plate fixedly installed below it moves synchronously. A sponge installed in the cleaning plate contacts and cleans the surface of the detection camera, ensuring the accuracy of the detection camera's identification. The sponge on the cleaning plate is manually replaced periodically. When the reciprocating mechanism is working, that is, when the telescopic cylinder drives the connecting slider to move left and right, the connecting slider drives the connecting rod mounted above it to move synchronously. The pulling and pushing action of the connecting rod drives the mounting plate to rotate, thereby causing the mounting plate to drive the abutment roller to rotate. The striking ball outside the abutment roller strikes the storage box to generate vibration, using vibration to prevent peanuts from clogging inside the storage box. Attached Figure Description

[0016] 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.

[0017] Example 1: Please refer to Figures 1-4 In order to achieve the purpose of detecting missed seeds and replanting, this embodiment provides the following technical solution, which specifically discloses: a replanting pipe 1 with equal spacing and a storage box 2 fixedly installed above the replanting pipe 1. The replanting pipe 1 is fixedly installed between the replanting pipe 1 and the planter body 4 through the mounting frame 3. The replanting pipe 1 corresponds one-to-one with the replanting pipe of the planter body 4. A detection camera 6 corresponding to the position of the replanting pipe 1 is fixedly installed on the lower surface of the mounting frame 3. A solenoid valve 5 for controlling the falling of peanut seeds is installed on the outside of the replanting pipe 1. The storage box 2 is connected to the replanting pipe 1. The solenoid valve 5 is associated with and controlled by the detection camera 6.

[0018] When using this invention, the replanting pipe 1 is first fixedly installed on the mounting frame 3. Then, the mounting frame 3 is fixedly installed between the planter body 4 and the planter body 4. The planter body 4 moves and sows peanuts under the drive of an agricultural tractor. At this time, the detection camera 6 under the mounting frame 3 is periodically turned on to photograph the peanuts sown in the field and uses visual technology to identify them. The periodic opening time of the detection camera 6 is determined according to the sowing spacing, that is, the sowing spacing / forward speed = the opening frequency of the detection camera 6. When the detection camera 6 identifies peanuts when taking pictures, it means that no peanuts have been missed. When it does not identify peanuts when taking pictures, it means that peanuts have been missed. At this time, a control signal is sent to open the solenoid valve 5, and the peanuts in the storage box 2 are discharged through the replanting pipe 1 to achieve the purpose of replanting.

[0019] The specific control flow between the detection camera 6 and the solenoid valve 5 is as follows: S1. Image acquisition: The detection camera 6 is turned on periodically and takes pictures. The images are analyzed using the controller (CCD technology) to identify whether there are peanuts. S2, control output: qualified signal → output high level, close solenoid valve 5; unqualified signal → output low level, open solenoid valve 5.

[0020] Example 2: Please refer to Figures 5-6 In order to ensure the detection effect, this embodiment provides the following technical solution, which specifically discloses: A cleaning plate 7 with a sponge structure is provided below the mounting frame 3. The cleaning plate 7 cleans the dust on the surface of the detection camera 6 by moving left and right through a reciprocating mechanism. The reciprocating mechanism includes a connecting slider 8 installed inside the mounting frame 3. The cleaning plate 7 is fixedly installed at the lower end of the connecting slider 8. The connecting slider 8 is slidably connected to a linear slide rail 9, and the linear slide rail 9 is fixedly installed on the inner surface of the mounting frame 3. A horizontally arranged telescopic cylinder 10 is fixedly installed inside the mounting frame 3. The front end of the telescopic cylinder 10 is fixedly installed with the connecting slider 8 and drives the connecting slider 8 to move left and right.

[0021] During the intervals when the inspection camera 6 is periodically opened, the telescopic cylinder 10 is activated. The telescopic cylinder 10 drives the connecting slider 8 to move back and forth on the outside of the linear slide rail 9. During the movement of the connecting slider 8, the cleaning plate 7 below it moves synchronously. The sponge installed in the cleaning plate 7 is used to wipe and clean the surface of the inspection camera 6, reducing dust adhesion and improving inspection accuracy. The sponge on the cleaning plate 7 is fixed by adhesive and is replaced by staff periodically.

[0022] Example 3: Please refer to Figure 7 In order to reduce clogging, this embodiment provides the following technical solution, which specifically discloses: an installation plate 11 is rotatably installed on the upper surface of the mounting bracket 3, a connecting rod 12 is rotatably installed between the lower surface of the installation plate 11 and the upper surface of the connecting slider 8, an abutting roller 13 is coaxially fixedly installed on the upper surface of the installation plate 11 and abuts against the outer surface of the storage box 2, and a tapping ball 14 with a protruding structure is fixedly installed on the outer surface of the abutting roller 13.

[0023] During the movement of the connecting slider 8, the connecting rod 12 mounted above it moves synchronously. Under the pushing and pulling action of the connecting rod 12, the mounting plate 11 rotates. The mounting plate 11 drives the abutting roller 13 above it to rotate. When the abutting roller 13 rotates, the striking ball 14 on its outside strikes the storage box 2, causing the storage box 2 to vibrate and reducing the possibility of peanuts getting stuck in the storage box 2.
