Technical Field

[0001] The utility model belongs to the technical field of equipment for university greenhouse experimental fields, and particularly relates to a rapid zoning device for university greenhouse experimental fields. Background Technique

[0002] During the planting and teaching processes in university greenhouse experimental fields, due to the differences in the experimental frequencies and research objects, the experimental fields are more characterized by flexible zoning, small area, diverse planted crops, and indoor operation. Based on these characteristics, universities need to carry out technical research and product development in various aspects such as green environmental protection, automation, high efficiency, miniaturization, and labor saving for experimental devices. The continuous upgrading of the zoning device technology and products for experimental fields has become an important issue faced and to be solved in university laboratory teaching and research. Currently, in domestic universities, the coverage and technological development of the zoning device for greenhouse experimental fields are in a blank stage, and it is quite common to use various human and material resources to replace equipment. The current situation of the zoning methods for university experimental fields has restricted the research speed of university teachers on the experimental object crops. Therefore, in order to accelerate the research frequency of experimental crops and increase the number of comparative experiments, a brand-new zoning device for greenhouse experimental fields is needed to solve the problems of flexible zoning, green environmental protection, and planting teaching in indoor or greenhouse experimental fields.

[0030] Refer to the appended Figure 1 drawing and the appended Figure 2 drawing.

[0031] The power and control component 1 includes a power nickel-metal hydride battery 11, a controller 12, a servo motor 13, and a remote control 14. The battery 11 provides power output for the operation of the entire zoning device, and the working time requirement is met by single charging through selecting the capacity of the battery; the controller 12 is connected to the power nickel-metal hydride battery 11 and the servo motor 13, and the remote control 14 and the controller 12 are connected by a wireless signal. The controller 12 is used to control the operation of the servo motor 13 according to the remote control instructions. The controller 12 provides signal output for the steering, speed and coordination of the two servo motors 13; the servo motor 13 provides torque output for the reducer 21; the remote control 14 and the controller transmit pulse signals, thereby completing the control of the operation of the entire device and the action of the zoning leveling working part 4. Through the power and control component 1, the green environmental protection, flexible operation, and constant-speed cruising operation of the device in indoor farming are realized.

[0032] The crawler and transmission component 2 is installed on both sides of the middle support frame 33 and includes a crawler 21, a belt pulley 22, and a reducer 23. The servo motor 13 is connected to the reducer, the reducer is connected to the belt pulley 22, and the belt pulley 22 is connected to the crawler 21. Through the check of the working resistance and working width, the miniaturized crawler 21 and belt pulley 22 are developed, and at the same time, the reducer 23 is configured according to the running speed of the device to meet the miniaturization requirement of the entire device. Through the crawler and transmission component 2, the requirements of stable operation during farming and rapid zoning during work of the device are realized.

[0033] The device bench 3 includes a front hanger 31, a middle support frame 33, and a rear bracket 32 that are connected in sequence from front to back. The front hanger 31 is used to bear various loads borne by the partition leveling working part 4 and install a laser rangefinder 6. The rear bracket 32 is used to install a partition marking board 5. The middle support frame 33 is used to install power and control components 1 and connect crawlers and transmission components 2. Through the development of various loads and mechanisms, the entire greenhouse experimental field rapid zoning device is structurally integrated through the device bench 3, achieving miniaturization of space. Through the device bench 3, the device realizes diversification in functions to meet the experimental field tillage requirements of different scenarios.

[0034] Refer to Figures 3 to 6 , the partition leveling working part 4 includes a width-adjustable partition board 41, a vertical displacement push rod 42, an adjustable rotary arm 43, and a width-adjustable electric push rod 44. The width-adjustable partition board 41 has two side plates connected at a certain angle at the front end, and a rear vertical plate is fixedly connected to the two side plates; a wing plate is hinged to the rear end of each of the two side plates.

[0035] One end of the vertical displacement push rod 42 is fixedly connected to the front side of the front hanger 31, and the other end of the vertical displacement push rod 42 is fixedly connected to the rear vertical plate of the width-adjustable partition board 41. An adjustable rotary arm 43 is provided on each side of the displacement push rod 42. One end of the adjustable rotary arm 43 is fixedly connected to the front side of the front hanger 31, and the other end is fixedly connected to the rear vertical plate of the width-adjustable partition board 41; the rear vertical plate of the width-adjustable partition board 41 and the wing plate are connected by a width-adjustable electric push rod 44; the controller 12 is connected to the width-adjustable electric push rod 44 and the vertical displacement push rod 42.

[0036] When the controller 12 receives the width adjustment signal sent by the remote controller 14, the controller 12 then outputs current to the width-adjustable electric push rod 44. The width-adjustable partition board 41 forms a displacement stroke through the action of the width-adjustable electric push rod 44 and cooperates with the hinge 411 to realize the width adjustment of the width-adjustable partition board 41, and finally meet the requirements of the planting widths of different experimental crops and the partition widths, as shown in Figure 2 and Figure 3 ; when the controller 12 receives the depth adjustment signal sent by the remote controller 14, the controller 12 then outputs current to the vertical displacement push rod 42. The displacement stroke of the vertical displacement push rod 42 drives the rotation of the adjustable rotary arm 43, realizing the control of the experimental field partition depth in different usage scenarios. Through the partition leveling working part 4, the multi-scenario function applicable to the device is realized, as shown in Figure 4 .

[0037] The partition scribing board 5 is installed on the rear bracket (32) at the rear side of the partition pushing and leveling working part 4. Multiple ones can be set as required and can be adjusted up, down, left and right to achieve the synchronous scribing function in the partitioned area. By adjusting the spacing between the scribing boards 5 and increasing the number of the scribing boards 5, the requirements of different line distances and line numbers are met, the diversification of the line widths within the functional partition is realized, and then the diversification of the planting types in the experimental field is realized, so as to conduct the comparative study of the planting data.

[0038] The laser distance measuring ruler 6 and the reference object matched with it are used to record the working distance during the tillage of the whole device, and the preset partition size is detected in real time, so as to improve the accuracy of the tillage area and distance of the device for the experimental field and reduce the manual measurement link.

[0039] See Figures 7 to 11 , before the experimental field rapid partition device works, the partition pushing and leveling working part 4 is adjusted to the maximum vertical upward position, the whole device is perpendicular to the experimental field ridge 7, the laser ruler 6 is turned on, when the power and control component 1 is started, the crawler and transmission component 2 starts to work, and the partition scribing board 5 is adjusted to the proper position and state as required, and the device moves forward, see Figure 5 .

[0040] After the experimental field rapid partition device works, remotely control and adjust the vertical push rod 42 of the partition working part until the partition working part is flush with the working surface. Along with the forward movement, a new wide partition 8 with a flat and marked line is formed. By adjusting the displacement stroke of the width-adjusting electric push rod 44 of the partition working part, different partition widths are realized. By changing the number and position of the rear partition scribing boards 5, a new narrow partition 9 with a marked line is formed, see Figure 6 .

[0041] The whole technical route adopts the forward innovation R & D means of the whole process of two-dimensional design, three-dimensional design, calculation, physical research and development and experimental verification of related structural parts, meeting the requirements of various actual application scenarios.
