Description

Technical Field

[0001] This utility model relates to the field of intelligent counting instruments for fruit tree fruit load, and in particular to a handheld fruit tree fruit load counter with a self-cleaning lens. Background Technology

[0002] In modern agricultural planting, technological means are often used to assist production. For example, in the fruit harvesting stage, fruit counting devices are used to count the number of fruits, avoiding production problems such as high labor intensity, long time consumption and low accuracy caused by manual counting. By measuring the number of fruits by fruit counting devices, it is possible to estimate yield, regulate resources, and collect relevant data such as flower and fruit management technology verification, physiological fruit drop research and variety breeding.

[0003] Currently, fruit counting devices often use visual recognition technology to determine the number of fruits. In their specific structure, the fruit counting device is equipped with a camera that takes pictures of the fruit trees and uses an image processing module to identify the fruits to determine the number of fruits. The camera is also the component that acquires information. However, in daily use, it is necessary to wipe the outer surface of the camera frequently to keep it clean, so as to avoid the camera from blurring due to blurring and affecting the accuracy of recognition. Therefore, it is necessary to carry a cleaning cloth and take it out when needed, which is extremely inconvenient. In addition, because manual wiping of the camera can easily scratch the camera or form fiber debris on the camera due to excessive force, which also affects the clarity of the camera. Utility Model Content

[0004] The purpose of this invention is to provide a handheld fruit tree fruit counter with a self-cleaning lens, which allows for convenient wiping of the camera lens while preventing the camera lens from being scratched or having fiber debris attached.

[0005] The technical solution provided by this utility model is as follows: a handheld fruit tree fruit counting instrument with self-cleaning lens, including a shell, a screen and buttons on the inner side of the shell, a camera on the outer side of the shell, a sliding bracket and a guide rail for guiding the sliding bracket to move back and forth on opposite sides of the camera on the outer side of the shell, the sliding bracket slidingly engaging with the guide rail, a roller assembly on the sliding bracket rotatingly engaging with the sliding bracket, and a synchronously rotating lens cloth sleeved on the roller assembly, when the sliding bracket moves from one side of the camera to the opposite side, the lens cloth abuts against and rotates friably with the outer side of the camera.

[0006] In the aforementioned handheld fruit tree fruit counting instrument with self-cleaning lens, the roller assembly includes two rollers that rotate with the sliding support. The two rollers are spaced apart along the extension direction of the guide rail. The lens cloth is sleeved on the two rollers and rotates in friction with them.

[0007] In the aforementioned handheld fruit tree fruit counting instrument with self-cleaning lens, the sliding bracket has a locking part on the side opposite to the camera that can hold a finger.

[0008] In the aforementioned handheld fruit tree fruit counting instrument with self-cleaning lens, the guide rail includes two sliding rails arranged opposite to each other on both sides of the camera. Sliders are provided on both opposite sides of the sliding bracket. The two sliders correspond one-to-one with the two sliding rails and slide in cooperation.

[0009] In the aforementioned handheld fruit tree fruit counting instrument with self-cleaning lens, a positioning block is provided on one side of the camera, and a permanent magnet is provided on the opposite side of the camera. Both the positioning block and the permanent magnet are located on the moving path of the sliding bracket, and the sliding bracket is provided with a magnetic attractor for magnetically connecting with the permanent magnet.

[0010] In the aforementioned handheld fruit tree fruit counter with self-cleaning lens, the camera extends to the outer side of the outer surface of the housing, the lens cloth is spaced apart from the outer surface of the housing, and the distance between the lens cloth and the outer surface of the housing is equal to the distance between the outer surface of the camera and the outer surface of the housing.

[0011] In the aforementioned handheld fruit tree fruit counting instrument with self-cleaning lens, the sliding bracket is provided with a protective cover that opens towards the outer shell, the roller assembly is located inside the protective cover, and the inner wall of the protective cover is provided with a rubber strip that is arranged along the width of the lens cloth, the rubber strip abutting against the lens cloth.

[0012] In the aforementioned handheld fruit tree fruit counting instrument with self-cleaning lens, one side of the rubber strip is provided with an arc surface, which abuts against the lens cloth.

[0013] In the aforementioned handheld fruit tree fruit counter with self-cleaning lens, the protective cover has a window, the window has a cover, the cover is detachably connected to the protective cover, and the rubber strip is provided on the cover.

[0014] In the aforementioned handheld fruit tree fruit counter with self-cleaning lens, the housing contains an MCU module, an image processing module, a GPS and network module, a signal triggering module, and a power supply module. The MCU module is electrically connected to the image processing module, the GPS and network module, the signal triggering module, and the power supply module, respectively. The image processing module is electrically connected to the camera, and the signal triggering module is connected to the button.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows: This technical solution involves setting guide rails around the camera to guide the sliding wiping brackets on the guide rails to move back and forth on opposite sides of the camera. Each time the sliding wiping bracket moves towards the camera, it drives the roller assembly to approach the outer side of the camera until the lens cloth on the roller assembly comes into contact with the outer side of the camera. After the lens cloth comes into contact with the outer side of the camera, as the sliding wiping bracket continues to move, friction is generated between the lens cloth and the outer side of the camera. The interaction force generated by the friction pushes the lens cloth to rotate around the rotation fulcrum of the roller assembly, that is, the lens cloth and the outer side of the camera move relative to each other. This allows the lens cloth to wipe the outer side of the camera with friction while reducing the frictional resistance, thereby avoiding scratches on the outer side of the camera due to excessive frictional resistance. It also reduces wear on the lens cloth, thus preventing the formation of fiber debris on the outer surface of the camera. This enables convenient wiping of the camera of the fruit counting instrument while preventing the camera from being scratched or having fiber debris attached. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0019] Example 1: like Figure 1-7 As shown, a handheld fruit tree fruit counter with self-cleaning lens includes a housing 10. The inner side of the housing 10 is provided with a screen and buttons, and the outer side of the housing 10 is provided with a camera 110. The outer side of the housing 10 is also provided with a sliding bracket 20 and a guide rail for guiding the sliding bracket 20 to move back and forth on opposite sides of the camera 110. The sliding bracket 20 is slidably engaged with the guide rail. The sliding bracket 20 is provided with a roller assembly, which is rotatably engaged with the sliding bracket 20. A synchronously rotating lens cloth 206 is sleeved on the roller assembly. When the sliding bracket 20 moves from one side of the camera 110 to the opposite side, the lens cloth 206 abuts against the outer side of the camera 110 and rotates due to friction.

[0020] The specific working principle is as follows: Guide rails are set around the camera 110, guiding the sliding friction bracket 20 on the guide rails to move back and forth on opposite sides of the camera 110. Each time the sliding friction bracket 20 moves towards the camera 110, it drives the roller assembly to approach the outer surface of the camera 110 until the lens cloth 206 on the roller assembly comes into contact with the outer surface of the camera 110. After the lens cloth 206 contacts the outer surface of the camera 110, as the sliding friction bracket 20 continues to move, friction is generated between the lens cloth 206 and the outer surface of the camera 110. Through the interaction force generated by this friction, the lens cloth 206 moves in the opposite direction... The lens cloth 206 is rotated around the pivot point of the roller assembly, which causes relative movement between the lens cloth 206 and the outer surface of the camera 110. This allows the lens cloth 206 to wipe the outer surface of the camera 110 with friction while reducing the frictional resistance, thus preventing scratches on the outer surface of the camera 110 due to excessive frictional resistance. It also reduces wear on the lens cloth 206, thereby preventing the formation of fiber debris on the outer surface of the camera 110. This enables convenient wiping of the camera 110 of the fruit counting instrument while preventing the camera 110 from being scratched or having fiber debris attached.

[0021] In a further improvement, the roller assembly includes two rollers that rotate with the sliding support 20. The two rollers are spaced apart along the extension direction of the guide rail. The lens cloth 206 is fitted on the two rollers and rotates in friction with them.

[0022] The arrangement of the two rollers gives the roller assembly a greater length in the extension direction of the guide rail, which in turn lengthens the lens cloth 206 sleeved on the roller assembly (specifically, sleeved on the two rollers), indirectly increasing the contact area between the lens cloth 206 and the camera 110, changing from line contact to surface contact, thus improving cleaning ability. After the increased contact area, the lens cloth 206 abuts against the outer side of the camera 110, and also moves relative to the camera 110 as the sliding bracket 20 continues to move. That is, the lens cloth 206 still rotates around the rotation fulcrum of the roller assembly (specifically, the rotation fulcrum of the rollers and the sliding bracket 20).

[0023] Preferably, the sliding bracket 20 has a locking part 203 on the side away from the camera 110 that can hold a finger.

[0024] In practical applications, by inserting a single finger into the locking part 203, the sliding bracket 20 can be moved on the outer casing 10, allowing both hands to still hold the fruit counter and keep the screen within the field of vision, reducing the difficulty of operation and improving the convenience and practicality of operation.

[0025] In this embodiment, the guide rail includes two slide rails 108 that are arranged opposite to each other on both sides of the camera 110. Slider 201 is provided on both opposite sides of the sliding bracket 20. The two sliders 201 correspond one-to-one with the two slide rails 108 and slide in cooperation.

[0026] like Figure 6 As shown, in the specific configuration, the slide rail 108 has an L-shaped cross-section. The vertical side of the slide rail 108 is located on the outer side of the housing 10, and the horizontal side is located towards the sliding bracket 20. The slider 201 on the sliding bracket 20 is located between the horizontal side of the slide rail 108 and the outer side of the housing 10.

[0027] In some embodiments, sliders 201 are also provided on opposite sides of the locking part 203, that is, sliders 201 are provided on both the sliding bracket 20 and the locking part 203. All sliders 201 slide in cooperation with the slide rail 108 to improve movement stability.

[0028] Combination Figure 2 , Figure 4 and Figure 6 As shown, another improvement is that a positioning block 109 is provided on one side of the camera 110, and a permanent magnet 112 is provided on the opposite side of the camera 110. The positioning block 109 and the permanent magnet 112 are both located on the moving path of the sliding bracket 20. The sliding bracket 20 is provided with a magnetic attractor 204 for magnetically connecting with the permanent magnet 112.

[0029] The positioning block 109 is designed to allow the housing 10 to press against the sliding bracket 20, preventing the sliding bracket 20 from slipping off the guide rail from one side of the camera 110. The permanent magnet 112 and the magnetic attractor 204 are designed to allow the housing 10 to magnetically connect to the magnetic attractor 204 through the permanent magnet 112, preventing the sliding bracket 20 from slipping off the guide rail from the opposite side of the camera 110. At the same time, the sliding bracket 20 is temporarily fixed in its initial position, and can only be pushed or pulled when external force is applied, preventing the sliding bracket 20 from sliding randomly.

[0030] In the specific configuration, the magnetic 204 is located on one side of the outer surface of the outer casing 10 adjacent to the card slot 203.

[0031] Combination Figure 4 and Figure 6 As shown, in another preferred embodiment, the camera 110 extends to the outer side of the outer side of the housing 10, and the lens cloth 206 is spaced apart from the outer side of the housing 10. The distance between the lens cloth 206 and the outer side of the housing 10 is equal to the distance between the outer side of the camera 110 and the outer side of the housing 10.

[0032] The camera 110 and the lens cloth 206 are designed to avoid the lens cloth 206 from contacting the outer surface of the housing 10, and only contact the outer surface of the camera 110. This design is specifically for wiping the camera 110, avoiding long-term scratching of the outer surface of the housing 10, enhancing the cleaning resistance of the lens cloth 206 and reducing wear to extend its service life.

[0033] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a further improvement of this embodiment, the sliding bracket 20 is provided with a protective cover 202 that opens toward the outer shell 10, the roller assembly is provided inside the protective cover 202, and the inner wall of the protective cover 202 is provided with a rubber strip 208 that is provided along the width of the lens cloth 206, and the rubber strip 208 abuts against the lens cloth 206.

[0034] The protective cover 202 is designed to prevent dust, water droplets, and foreign objects from falling directly onto the lens cloth 206, thus improving the cleaning resistance of the lens cloth 206. The rubber strip 208 allows the protective cover 202 to scrape the lens cloth 206. The lens cloth 206 collects dust, water droplets, and foreign objects on the lens cloth 206 through physical interception and electrostatic adsorption, preventing dirt from remaining on the lens cloth 206 and keeping the lens cloth 206 in a relatively clean state, thereby improving the cleaning resistance of the lens cloth 206.

[0035] like Figure 5 As shown, preferably, one side of the rubber strip 208 is provided with an arc surface, which abuts against the lens cloth 206.

[0036] The curved surface design reduces the frictional resistance between the rubber strip 208 and the lens cloth 206.

[0037] In the specific configuration, the protective cover 202 is provided with an installation strip 207 that is parallel to the rubber strip 208, and one side of the rubber strip 208 is detachably attached to the installation strip 207.

[0038] Another preferred embodiment is that the protective cover 202 has a window, and the window has a cover 205. The cover 205 is detachably connected to the protective cover 202, and a rubber strip 208 is provided on the cover 205.

[0039] The rubber strip 208 is provided on the cover 205, so that when the cover 205 is opened from the protective cover 202 or the cover 205 is removed and the window is exposed, the rubber strip 208 is exposed outside the protective cover 202 together, which facilitates cleaning of the rubber strip 208 and its surrounding area.

[0040] In the specific configuration, one side of the cover 205 is hinged to the protective cover 202, and the opposite side is snapped into the protective cover 202 in a detachable manner.

[0041] Combination Figure 1 and Figure 7 As shown, in this embodiment, the housing 10 is equipped with an MCU module, an image processing module 50, a signal triggering module 40, a GPS and network module 30, a signal triggering module 40, and a power supply module 60. The MCU module is electrically connected to the image processing module 50, the GPS and network module 30, the signal triggering module 40, and the power supply module 60, respectively. The image processing module 50 is electrically connected to the camera 110, and the signal triggering module 40 is connected to the button.

[0042] In specific applications, the housing 10 is also equipped with an antenna 107, which is electrically connected to the GPS and network module 30; the buttons include a directional button 101, a joystick button 102, a calibration button 103, a rewind button 104, a start button 105, and a power button 106; in addition, the housing 10 is also equipped with a storage module 70 for storing data, which is electrically connected to the screen, the GPS and network module 30, and the image processing module 50 respectively.

[0043] During the recognition process, the image processing module 50 segments the acquired image based on the RGB color model, enabling the fruit-bearing technology instrument to automatically identify the fruit on the tree under natural lighting conditions and count the number of fruits through the MCU module. In practical applications, the fruit counter achieves full-process control through physical buttons and has the ability to work in both offline processing and data transmission modes.

[0044] The system architecture includes a human-machine interaction unit, a control unit, an image acquisition unit, a data transmission unit, and an MCU unit. The human-machine interaction unit includes a touch screen and a three-in-one module for power supply / charging / data transmission with an integrated USB interface 111. The control unit includes a physical control panel (power button 106, start button 105, playback button 104, calibration button 103, joystick button 102, and directional buttons 101). The image acquisition unit includes a 5-megapixel wide-angle visible light imaging module (i.e., camera 110) with an effective working distance of 2-5m. The data transmission unit includes a local storage module with integrated GPS positioning and network transmission components.

[0045] In some implementations, the MCU module is located in the cloud server. That is, the fruit counter itself does not have an MCU module and does not perform statistical calculations within the fruit counter. Instead, it outputs data to the cloud server, which performs the calculations. After the cloud server sends back the calculation results, the fruit counter parses the results and displays the measurement and statistical results on the screen.

[0046] The specific usage and operation process is as follows: Device startup: The system is activated via physical buttons, and joystick 102 controls the wide-angle camera to select the target area; Data acquisition: Capture images of fruit trees containing GPS location information; raw data is temporarily stored in the local storage module. Intelligent processing: Triggers local algorithms to perform RGB color model analysis, and uses image segmentation to label the location and quantity of fruits; Output: The processed image (including fruit selection marks and GPS data) is displayed in real time on the touchscreen, and button correction is supported.

[0047] This embodiment also has the following technical effects: First, the measurement is rapid, achieving the entire process of image acquisition → analysis → result display within 200ms, which is 8-12 times more efficient than manual statistics; Second, it has high accuracy. Based on the RGB color model, it segments the acquired images and achieves an accurate recognition rate of 90%, eliminating subjective errors from manual operation and improving precision. Third, it is easy to operate, with a simple device structure, and is flexible and convenient to operate by hand with buttons, while also having good ease of operation and portability; Fourth, it has a wide range of applications and is suitable for measuring the fruit load of different fruit trees, such as apples, pears, and citrus, making it highly versatile.

[0048] Through actual testing, this instrument outperforms manual visual counting of fruit loads in both measurement accuracy and efficiency, meeting the practical needs of counting the number of fruits on a single fruit tree in agricultural planting.

[0049] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
