Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a single assembly detection device for a seed drill. Background Art

[0002] The drill is used for sowing. When the drill is operating, the seed wheel rotates, and the seeds are discharged from the seed box into the seed guide tube and fall into the groove opened by the sowing disc. The seeds are then covered and compacted by the pressing wheel. In order to ensure the sowing efficiency, multiple drill units are installed on each drill. In the prior art, each drill unit is assembled separately, and then multiple drill units are installed on the drill. Since the structure for installing the drill units adopts front and rear buckles, the plates are in contact with the rectangular tube surface, and the two plates are very easy to deform during the tightening process. The deformation of multiple drill units is inconsistent, resulting in inconsistent heights of the multiple drill units and the heights of the pressing wheels. The pressing pressure of the pressing wheels of the multiple units is also inconsistent, which affects the sowing effect. Therefore, it is necessary to adjust the multiple drill units. Since the height of each drill unit, the height of the pressing wheel, and the pressing force cannot be accurately identified, the adjustment process takes too long, seriously affecting production efficiency and timely product delivery. On average, the installation of each drill unit's 24 units requires 90 minutes / 2 people, wasting a lot of manpower and material resources. Utility Model Content

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figures 1 to 5As shown, the utility model discloses a drill unit assembly and detection device, including a base platform 1, with inclined inclined plates 12 at both ends of the base platform 1, which are convenient for taking and placing the drill unit 8 and reducing the difficulty of assembly. A detection component and a parallel support frame 2 and a spacing adjustment rail 3 are provided on the base platform 1, and the support frame 2 is located above the spacing adjustment rail 3. The two ends of the support frame 2 are connected to the lifting mechanism and are lifted and lowered under the action of the lifting mechanism. The spacing adjustment rail 3 is connected to the translation mechanism and moves back and forth under the action of the translation mechanism. The support frame 2 is used to support multiple drill units 8, and a plurality of positioning components are provided on the spacing adjustment rail 3. The positioning components are used to position the sowing disc 8.1 of the drill unit 8, wherein the sowing disc 8.1 is a metal disc. The position and number of the detection components correspond to the position and number of the drill unit 8, wherein the detection components are provided with 20 groups or 24 groups, and each group of detection components includes a force sensor 5, a linear displacement sensor 6 and a laser displacement sensor Device 7, force sensor 5 is used to detect the pressure value of the pressing wheel 8.2 of the drill unit 8. Specifically, a flat-plate measuring head is provided on the force sensor 5, and the flat-plate measuring head contacts the bottom surface of the sowing disc 8.1 to detect the pressing force of the sowing disc 8.1. The linear displacement sensor 6 is used to detect the height of the sowing disc 8.1. The laser displacement sensor 7 is used to detect the height of the pressing wheel 8.2. The pressing wheel 8.2 is a rubber wheel and adopts a non-contact laser displacement sensor 7 to ensure the accuracy and precision of the measurement results. The detection component, lifting mechanism and translation mechanism are respectively communicated with the PLC controller, and the PLC controller is communicated with the acquisition and analysis system. The PLC controller realizes the logic control and signal acquisition of the assembly detection equipment. The acquisition and analysis system realizes the communication connection with the PLC controller through industrial Ethernet, completes the test data acquisition and processing, can completely and correctly collect various waveforms, perform data processing and analysis, and realize real-time trend curves and historical data records.

[0023] Furthermore, an operation interface 4 and a control box 10 are installed on the base platform 1. The operation interface 4 is communicatively connected to the control box 10. The PLC controller and the acquisition and analysis system are arranged in the control box 10. By inputting control instructions such as lifting and lowering the support frame 2 or moving the spacing adjustment track 3 on the operation interface 4, the operation interface 4 transmits the signal to the control box 10. The control box 10 controls the operation of the lifting mechanism and the translation mechanism to meet the measurement of the seed drill unit 8.

[0024] In this embodiment, both ends of the spacing adjustment track 3 are movably mounted on longitudinal linear guides 11 via sliders. These guides are connected to the output end of the translation mechanism. These guides support and guide the spacing adjustment track 3, enhancing the smooth movement of the multiple seed drill units 8, reducing vibration, and ensuring the accuracy of the test results.

[0025] Specifically, the translation mechanism includes a servo motor 15 and a horizontal shaft. The output end of the servo motor 15 is connected to the horizontal shaft, and the spacing adjustment track 3 is threadedly connected to the horizontal shaft via a connecting block. When the servo motor 15 is in operation, it drives the horizontal shaft to rotate. The horizontal shaft, through the connecting block, drives the spacing adjustment track 3 along the longitudinal linear guide 11, thereby driving the seeding disc 8.1 of the seed drill unit 8 to move, meeting the measurement requirements of the seeding disc 8.1.

[0026] The lifting mechanism includes a servo motor 2 and a vertical shaft. The servo motor 2 is installed in a protective box 17 at both ends of the base platform 1. The output end of the servo motor 2 is connected to the vertical shaft, and the vertical shaft is threadedly connected to the support plate 16. The two ends of the support frame 2 are installed on the support plate 16. When the servo motor 2 is working, it drives the vertical shaft to rotate, drives the support plate 16 and the support frame 2 to rise and fall, thereby driving the pressure wheel 8.2 of the seed drill unit 8 to rise and fall, and realizes the detection of the pressure value and height of the pressure wheel 8.2 to ensure the accuracy of the detection results. Among them, the servo motor 1 15 and the servo motor 2 both use absolute value servo motors, and the horizontal and vertical axes use precision T-shaped screws to achieve precise control of the position of multiple seed drill units 8, thereby ensuring the consistency of the height of the seed drill unit 8, the consistency of the height of the pressure wheel 8.2, and the consistency of the pressure of the pressure wheel 8.2. Among them, the height of the seed drill unit 8 is the height of the sowing disc 8.1.

[0027] Furthermore, each group of the positioning components includes two positioning clamps 9, a positioning groove is formed between the two positioning clamps 9, and a guide slope is provided at the opening of the positioning groove, which guides and limits the seeding disc 8.1. The positioning clamps 9 are detachably mounted on the spacing adjustment track 3 through a clamping plate 18. When the position of the positioning clamp 9 is adjusted to the specified position, it is locked by the screws on the clamping plate 18 to ensure the firmness of the installation of the positioning clamp 9 and the accuracy of the test results. The positioning groove positions the seeding disc 8.1, ensures the accuracy of the assembly position, reduces the difficulty of assembly, and ensures the height consistency of the seeding disc 8.1 of multiple seed drill units 8. It can also adjust the distance between the positioning components according to the number of seed drill units 8 assembled, thereby meeting the assembly and testing requirements of different numbers of seed drill units 8, improving versatility, and reducing production costs.

[0028] Furthermore, a bracket 13 is mounted on the base platform 1 and is parallel to the spacing adjustment track 3. The force sensor 5 is detachably mounted on the bracket 13 via a second clamping plate 19. This ensures that the heights of the multiple force sensors 5 are consistent, ensuring the accuracy of the test results. Furthermore, the position of the force sensor 5 can be adjusted according to the number of seed drill units 8 to meet the assembly and testing requirements of different numbers of seed drill units 8, thereby improving versatility and reducing production costs.

[0029] The use process of this utility model is as follows:

[0030] Adjust the spacing between the multiple positioning components on the track 3 according to the test model of the seed drill and the spacing between the seed drill units 8;

[0031] Use push-pull quick clamps to fix the unit fixing frame 14 of the drill unit 8 on the support frame 2, and assemble multiple drill units 8 one by one;

[0032] After the multiple seed drill units 8 are assembled, the translation mechanism drives the spacing adjustment track 3 and the seeding disc 8.1 forward, and the multiple seed drill units 8 are synchronously moved to the detection position. The linear displacement sensor 6 is used to measure the height of each seeding disc 8.1, and the laser displacement sensor 7 is used to detect the height of the pressure wheel 8.2. The data is transmitted to the PLC controller, and the PLC controller transmits the signal to the collection and analysis system. The collection and analysis system calculates the height consistency error of the seeding disc 8.1 and the height consistency error of the pressure wheel 8.2 of the multiple seed drill units 8;

[0033] The lifting mechanism drives the support frame 2 and the pressing wheel 8.2 to move downward, so that the pressing wheel 8.2 falls onto the force sensor 5, and the pressing force of the pressing wheel 8.2 is measured by the force sensor 5. The consistency error of the pressing force of multiple pressing wheels 8.2 is calculated through the acquisition and analysis system. If the test data is not within the error range, the non-compliant seed drill unit 8 is adjusted according to the instructions of the operation interface 4 until the test data of the pressing force values of multiple pressing wheels 8.2 are within the error range. By controlling the lifting mechanism, the assembled seed drill unit assembly is lifted, the relevant tooling is disassembled, and the seed drill unit assembly that has been inspected is lifted off and separated from the assembly inspection equipment. The overall operation is simple and the measurement is accurate, which improves the assembly efficiency of the seed drill unit 8 installed on the seed drill and saves production costs.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
