Description

Technical Field

[0001] This utility model relates to the field of agricultural information technology, and in particular to a novel agricultural economic management information input device. Background Technology

[0002] Information entry devices refer to hardware devices used to convert non-digital information such as text, data, images, sounds, and physical characteristics into digital signals that can be recognized by computers and transmit them to storage or processing systems. The new agricultural economic management information entry device is designed specifically for agricultural economic management scenarios and is a customized information entry system that integrates new technologies.

[0003] Typically, a new type of agricultural economic management information entry device consists of a housing, a light shield, and a telescopic mechanism. Therefore, during use, the housing serves as the basic load-bearing structure of the device, providing installation and storage space for other core components such as cameras and QR code scanners. The light shield has the dual functions of blocking light and convenient storage, isolating various strong light interferences and ensuring the recognition accuracy of information collection components. The telescopic mechanism provides support when it is necessary to support the housing.

[0004] In some existing agricultural economic management information entry devices, when conducting agricultural product information entry work outdoors, direct sunlight can interfere with the light reception of core acquisition components such as cameras and QR code scanners, leading to excessive lens exposure, overexposed images, and blurred QR code recognition, making it difficult to complete the information entry of agricultural products. Therefore, a new type of agricultural economic management information entry device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of agricultural economic management information entry device, which aims to improve the problem that it is difficult to complete the entry of agricultural product information under direct strong light in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel agricultural economic management information input device includes a housing, an internal folding mechanism, an internal telescopic mechanism, and an external protective sleeve. The folding mechanism includes a light shield, the outer wall of which is slidably connected to the inside of the housing. Two fixed shafts are fixedly connected to the inside of the light shield. A drive plate is rotatably connected to the outer wall of each of the two fixed shafts. A movable shaft is rotatably connected to the rear side of the drive plate. A driven plate is rotatably connected to the top of the movable shaft. A connecting shaft is rotatably connected to the rear side of the driven plate. Two irregularly shaped hemispherical blocks are fixedly connected to the front side of the light shield. A disassembly assembly is slidably connected to the front side of the housing. Preferred: When working outdoors in agriculture, strong midday sunlight, field reflections such as those from crop leaves and water surfaces can directly affect the light reception stability of cameras and QR code scanners. A light shield can effectively isolate the effects of light refraction. The top of the housing has a space for storing the light shield. When the light shield is not needed, it can be stored inside the housing. When the light shield is stored inside the housing, it drives the drive plate to move into the groove on the top of the housing, thereby driving the driven plate connected to the top of the moving shaft to rotate around the connecting shaft fixed inside the housing until the drive plate and the driven plate are almost at the horizontal line, thus completing the storage of the light shield.

[0007] As a further description of the above technical solution: The disassembly assembly includes a dust cover, the rear side of which is slidably connected to the front side of the housing. Multiple irregularly shaped blocks are fixedly connected to the rear outer wall of the dust cover. Multiple connecting blocks are fixedly connected to the inside of the housing. Each of the multiple connecting blocks has a spring inside. A movable circular plate is fixedly connected to the bottom of the spring. A connecting ball is fixedly connected to the bottom of the movable circular plate. A linkage circular plate is slidably connected to the bottom of the movable circular plate. Preferred configuration: When carried daily or not in use, the dust cover is fastened to the transparent protective lens to isolate outdoor dust and dew from the lens, preventing dust and liquid from contaminating the lens of the information entry device and affecting information entry. The irregular block is fixed to the outside of the dust cover for engaging and disengaging the dust cover from the internal components of the housing. Due to its elastic material, the spring can drive the moving circular plate to reset. The compression of the spring allows the connecting ball to engage and disengage with the irregular block.

[0008] As a further description of the above technical solution: Each of the multiple telescopic mechanisms includes a telescopic circular plate, the outer walls of the multiple telescopic circular plates are slidably connected to the inside of the housing, a telescopic column is fixedly connected to the bottom of the telescopic circular plate, the telescopic column is provided with multiple threaded holes, a multiple linkage block is fixedly connected to the bottom of the housing, and bolts are slidably connected to the inside of the multiple linkage blocks. Preferably, when the operator needs to temporarily place the device for other operations while entering information in the field, the support frame can be released from the shell. The sliding of the telescopic column inside the shell allows the support frame to extend and retract. Bolts are used to fix the telescopic column's extension position and fix the telescopic column's extension height to meet the operator's required support frame height.

[0009] As a further description of the above technical solution: The drive plate is slidably connected to the outside of the housing, and the driven plate is slidably connected to the outside of the housing. Preferably, when the sunshade is retracted into the housing, the rotation of the drive plate causes the moving shaft, which is located inside the rear side of the drive plate, to move inside the groove opened inside the housing for the sunshade to be retracted, thereby causing the driven plate connected to the top of the moving shaft to rotate around the connecting shaft fixed inside the housing.

[0010] As a further description of the above technical solution: The top and bottom of the connecting shaft are fixedly connected to the inside of the housing, and the outside of the moving shaft is slidably connected to the inside of the housing. Preferably, the two connecting shafts are fixed in the grooves opened inside the housing, so that the driven plate rotates around the connecting shafts fixed inside the housing.

[0011] As a further description of the above technical solution: The rear sides of the two irregularly shaped hemispherical blocks are in contact with the front side of the housing, and the outer wall of the drive plate is rotatably connected to the interior of the rear side of the light shield; Preferably, when the irregular hemispherical block contacts the front side of the housing, it indicates that the light shield has been retracted into the housing. The outer wall of the drive plate is rotatably connected to the rear side of the light shield. When the light shield is retracted into the housing, the drive plate is in the groove on the rear side of the housing.

[0012] As a further description of the above technical solution: The two connecting balls are in contact with the outer wall of the irregular block on their adjacent sides, and the outer wall of the linkage circular plate is fixedly connected to the inside of the connecting block; Preferably, the dust cover is disassembled and installed by the contact ball and the irregular block, the outer wall of the linkage circular plate is fixedly connected to the inside of the connecting block, and the linkage circular plate restricts the movement of the connecting ball.

[0013] As a further description of the above technical solution: The bolt is externally rotatably connected to the inner wall of the threaded hole, and the telescopic column is externally slidably connected to the inside of the housing.

[0014] Preferably, the bolts are aligned with the threaded holes inside the telescopic column to fix the telescopic column's telescopic height. The telescopic column is slidably connected to the inside of the housing. The sliding of the telescopic column inside the housing allows the support frame to extend and retract for storage.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by pulling the irregular hemispherical block to drive the drive plate to rotate around the fixed axis, the driven plate to rotate around the fixed connecting axis, and the connecting ball inside the irregular block and the connecting block to engage and separate, and with the help of the spring elastic reset, the flexible unfolding and storage of the light shield and the dustproof effect of the information input device are achieved. Compared with the existing technology, which lacks targeted light shielding and the lens is easily contaminated by outdoor dust and dew, it takes into account the light shielding and dustproof needs of outdoor use.

[0016] 2. In this utility model, the telescopic mechanism inside the four corners of the bottom of the shell, the bolt fixing of the linkage block and the telescopic column, and the extension of the telescopic column by the sliding limit of the telescopic circular plate realize the height adjustment and stable support function of the telescopic column. Compared with the problem of the device being difficult to place stably on uneven ground in the field in the prior art, it plays a flexible adaptation to different ground heights and ensures the stability of the device when it is temporarily placed, thus improving the convenience and stability of agricultural field information entry.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: A novel agricultural economic management information input device, referring to... Figures 1 to 3 The device includes a housing 1, a folding mechanism 2 inside the housing 1, multiple telescopic mechanisms 3 inside the housing 1, and a protective sleeve 4 outside the housing 1. The protective sleeve 4 covers the outside of the housing 1 and buffers the impact force through its own elastic material, especially the protective protrusions at the corners, which can preferentially withstand the collision force and reduce the impact force on the information input device inside the housing 1. The folding mechanism 2 includes a light shield 21. During outdoor agricultural operations, strong midday sunlight, field reflections such as those from crop leaves and water surfaces, directly affect the light reception stability of cameras and QR code scanners. The light shield 21 effectively isolates the effects of light refraction. The outer wall of the light shield 21 is slidably connected to the inside of the housing 1. The top of the housing 1 has a space for storing the light shield 21. When not in use, the light shield 21 can be stored inside the housing 1. Two fixed shafts 22 are fixedly connected inside the light shield 21, and these fixed shafts 22 are welded to the light shield. The inner wall of the groove opened on the rear side of the light shield 21 is also open to facilitate the storage of the light shield 21. The outer walls of the two fixed shafts 22 are rotatably connected to the drive plate 23. When the light shield 21 is stored inside the housing 1, the light shield 21 drives the drive plate 23 to rotate around the fixed shaft 22. The rear inner side of the drive plate 23 is rotatably connected to the movable shaft 24. When the light shield 21 is stored inside the housing 1, the rotation of the drive plate 23 drives the movable shaft 24, which is located inside the rear inner side of the drive plate 23, to move inside the groove opened in the housing 1 for storing the light shield 21. A driven plate 25 is rotatably connected to the top interior of the moving shaft 24, and a connecting shaft 26 is rotatably connected to the rear interior of the driven plate 25. Since the two connecting shafts 26 are fixed in the grooves inside the housing 1, when the light shield 21 is retracted into the housing 1, the light shield 21 drives the drive plate 23 to move into the grooves at the top of the housing 1, thereby causing the driven plate 25 connected to the top of the moving shaft 24 to rotate around the connecting shafts 26 fixed inside the housing 1 until the drive plate 23 and the driven plate 25 are almost horizontal. At the line, the light shield 21 is retracted. Two irregularly shaped hemispherical blocks 27 are fixedly connected to the front side of the light shield 21. The two irregularly shaped hemispherical blocks 27 facilitate the retraction of the light shield 21. When the irregularly shaped hemispherical blocks 27 contact the front side of the housing 1, it means that the light shield 21 has been retracted into the housing 1. When the light shield 21 needs to be used, simply pull the irregularly shaped hemispherical blocks 27. The irregularly shaped hemispherical blocks 27 drive the light shield 21 so that the light shield 21 slowly disengages from the groove opened at the top of the housing 1. The front side of the housing 1 is slidably connected to the disassembly component 28. The disassembly component 28 includes a dust cover 281. When carried or not in use, the dust cover 281 is fastened to the transparent protective lens to prevent outdoor dust and dew from contaminating the lens and preventing dust mixed with liquid from contaminating the lens of the information entry device and affecting information entry. The rear side of the dust cover 281 is slidably connected to the front side of the housing 1. Multiple irregular blocks 282 are fixedly connected to the rear outer wall of the dust cover 281. The irregular blocks 282 are fixed to the outside of the dust cover 281 and are used for the engagement and disengagement of the dust cover 281 and the internal components of the housing 1. Multiple connecting blocks 283 are fixedly connected inside the housing 1. The connecting blocks 283 can be considered as the body of the housing 1, except that the connecting blocks 283 need to have grooves inside for the engagement and disengagement of the connecting components and the irregular blocks 282. Each of the multiple connecting blocks 283 has a spring 284 inside. The bottom of the spring 284 is fixedly connected to a movable circular plate 285. Due to its elastic material, the spring 284 can drive the movable circular plate 285 to reset. The bottom of the movable circular plate 285 is fixedly connected to a connecting ball 286. The connecting ball 286 contacts the irregular block 282 to complete the disassembly and installation of the dust cover 281. The bottom of the movable circular plate 285 is slidably connected to a linkage circular plate 287. A support column is connected between the movable circular plate 285 and the connecting ball 286. The support column moves up and down at the hole opened inside the linkage circular plate 287 to compress the spring 284 so that the connecting ball 286 can engage and disengage with the irregular block 282. Specifically, the irregularly shaped hemispherical block 27 is pulled outward, and the traction force of the irregularly shaped hemispherical block 27 drives the light shield 21 to move outward. At the same time, the light shield 21 drives the drive plate 23 on the outside of the fixed shaft 22 connected inside it to rotate and slide around the fixed shaft 22. Since the connecting shaft 26 of the two components is fixed and cannot move, the rotation of the drive plate 23 will drive the moving shaft 24 located inside the rear side of the drive plate 23. Under the transmission action of the moving shaft 24, the driven plate 25 located on the top outer wall of the moving shaft 24 will rotate synchronously around the connecting shaft 26. During this process, the drive plate 23 and the driven plate 25 will gradually approach each other. When the drive plate 23 is completely embedded inside the rear side of the light shield 21, the driven plate 25 and the light shield 21 will be in a near-contact state to complete the storage of the light shield 21 and complete the light shielding. After the photomask 21 is stored, the multiple irregularly shaped blocks 282 on the outer wall of the dust cover 281 need to be aligned with the groove opened on the front side of the housing 1. When the irregularly shaped block 282 is inserted into the groove, the connecting ball 286 inside the groove is squeezed, which drives the moving circular plate 285 connected to the top of the connecting ball 286 to compress the spring 284. With the help of the compression of the spring 284, the irregularly shaped block 282 can smoothly contact the inner wall of the groove. When the irregularly shaped block 282 contacts the inner wall of the groove, the squeezing force on the connecting ball 286 disappears. At this time, because the spring 284 has elastic restoring characteristics, it will drive the moving circular plate 285 and the connecting ball 286 to return to the initial state. Finally, the middle position of the irregularly shaped block 282 is in close contact with the bottom of the connecting ball 286, realizing the stable engagement of the irregularly shaped block 282 and the connecting ball 286.

[0021] Reference Figure 1 and Figure 4 Each of the multiple telescopic mechanisms 3 includes a telescopic circular plate 31, which can slide within holes opened inside the housing 1 to extend or retract the height of the support frame. When operators need to temporarily place the device for other operations while entering information in the field, the support frame can be extended from inside the housing 1. The presence of multiple telescopic mechanisms 3 ensures stability on uneven ground surfaces. The outer walls of the multiple telescopic circular plates 31 are slidably connected to the inside of the housing 1, and telescopic columns 32 are fixedly connected to the bottom of the telescopic circular plates 31. The telescopic columns 32 are located inside the housing 1. The sliding mechanism allows the support frame to extend and retract. The telescopic column 32 has multiple threaded holes 33 inside. Multiple linkage blocks 34 are fixedly connected to the bottom of the housing 1. Bolts 35 are slidably connected inside each linkage block 34. The bolts 35 are used to fix the telescopic position of the telescopic column 32. When the telescopic column 32 extends to the required height, the bolts 35 are aligned with the threaded holes 33 inside the telescopic column 32. The linkage blocks 34 and the telescopic column 32 are connected by the bolts 35 to fix the telescopic height of the telescopic column 32 to meet the support frame height required by the operator. Specifically, when the operator needs to temporarily place the device for other operations, the bolts 35 located on the inner wall of the linkage block 34 and the threaded hole 33, which are used to fix the linkage block 34 and the telescopic column 32, are removed. The telescopic column 32 located inside the four corners of the bottom of the housing 1 is pulled out to the height required by the operator. The telescopic circular plate 31 fixed at the top of the telescopic column 32 slides inside the groove opened inside the housing 1 and is difficult to disengage from the groove inside the housing 1. This limits the length of the telescopic column 32 that moves out of the housing 1. When facing different ground heights, the adjustable telescopic column 32 can meet the support at different heights at each support corner. After adjusting the required support height, the bolts 35 are inserted into the threaded hole 33 of the linkage block 34 at the same height to fix the support height of the telescopic column 32 at this time. When the support of the housing 1 is no longer needed, the bolts 35 are removed again, the telescopic column 32 is put back into the housing 1, and finally the bolts 35 are installed.

[0022] Reference Figures 1 to 3 The drive plate 23 is externally slidably connected to the inside of the housing 1. When the light shield 21 is retracted into the housing 1, the rotation of the drive plate 23 drives the moving shaft 24, which rotates inside the rear side of the drive plate 23, to move inside the groove opened inside the housing 1 for the light shield 21 to be retracted. The driven plate 25 is externally slidably connected to the inside of the housing 1. The light shield 21 drives the drive plate 23 to move into the groove opened at the top of the housing 1, thereby driving the driven plate 25 connected to the top of the moving shaft 24 to rotate around the connecting shaft 26 fixed inside the housing 1. The top and bottom of the connecting shaft 26 are respectively fixedly connected to the inside of the housing 1. The two connecting shafts 26 are fixed in the groove opened inside the housing 1, so that the driven plate 25 rotates around the connecting shaft 26 fixed inside the housing 1. The moving shaft 24 is externally slidably connected to the inside of the housing 1. The rear sides of the two irregularly shaped hemispherical blocks 27 contact the front side of the housing 1. When the irregularly shaped hemispherical blocks 27 contact the front side of the housing 1, it indicates that the light shield 21 has been retracted into the housing 1. The outer wall of the drive plate 23 is rotatably connected to the rear side of the light shield 21. When the light shield 21 has been retracted into the housing 1, the drive plate 23 is in the groove on the rear side of the housing 1. The adjacent sides of the two connecting balls 286 contact the outer wall of the irregularly shaped block 282. The connecting balls 286 contact the irregularly shaped block 282 to complete the protection. The dust cover plate 281 is disassembled and installed. The outer wall of the linkage circular plate 287 is fixedly connected to the inside of the connecting block 283. The linkage circular plate 287 restricts the movement of the connecting ball 286. The outer rotatable connection of the bolt 35 is connected to the inner wall of the threaded hole 33. The bolt 35 is aligned with the inside of the threaded hole 33 opened inside the telescopic column 32 to fix the telescopic height of the telescopic column 32. The outer slidable connection of the telescopic column 32 is connected to the inside of the housing 1. The sliding of the telescopic column 32 inside the housing 1 allows the support frame to be extended, retracted and stored. Specifically, when the sunshade 21 is retracted into the housing 1, the rotation of the drive plate 23 causes the moving shaft 24, which rotates inside the rear side of the drive plate 23, to move inside the groove opened inside the housing 1 for the sunshade 21 to be retracted. The two connecting shafts 26 are fixed in the groove opened inside the housing 1, thereby causing the driven plate 25 connected to the top of the moving shaft 24 to rotate around the connecting shaft 26 fixed inside the housing 1. When the irregular hemispherical block 27 contacts the front side of the housing 1, it indicates that the sunshade 21 has been retracted into the housing 1. At this time, the drive plate 23 is in the groove on the rear side of the housing 1, and the connecting ball 286 contacts the irregular block 282 to complete the disassembly and installation of the dust cover 281. The linkage circular plate 287 restricts the movement position of the connecting ball 286. The bolt 35 is aligned with the threaded hole 33 opened inside the telescopic column 32 to fix the telescopic height of the telescopic column 32. The sliding of the telescopic column 32 inside the housing 1 allows the support frame to be extended and retracted.

[0023] The implementation principle of this application embodiment is as follows: When the operator starts the information input device to prepare for outdoor information input and collection work, due to the influence of light refraction, the component light shield 21 needs to be opened first. During use, the component dust cover 281 must not be placed in front of the light shield 21, but must be stored in another independent space to avoid interfering with the normal operation of information collection equipment such as cameras. After use, the light shield 21 must be stored and folded into the component housing 1. First, the component irregular hemispherical block 27 is pulled outwards. The traction force of the irregular hemispherical block 27 drives the light shield 21 to move outward. At the same time, the light shield 21 drives the drive plate 23 on the outside of the fixed shaft 22 connected inside it to rotate and slide around the fixed shaft 22. Since the connecting shaft 26 of the two components is fixed and cannot move, the rotation of the drive plate 23 will drive the moving shaft 24 located inside the rear side of the drive plate 23. Under the transmission action of the moving shaft 24, the driven plate 25 located on the top outer wall of the moving shaft 24 will rotate synchronously around the connecting shaft 26. During this process, the drive plate 23 and The driven plate 25 will gradually move closer. When the driving plate 23 is fully embedded inside the rear side of the sunshade 21, the driven plate 25 and the sunshade 21 will be in near contact, thus completing the storage of the sunshade 21. After the sunshade 21 is stored, the multiple irregularly shaped blocks 282 on the outer wall of the dust cover 281 need to be aligned with the groove opened on the front side of the housing 1. When the irregularly shaped blocks 282 are inserted into the groove, the connecting ball 286 inside the groove is compressed, thereby driving the moving circular plate 285 connected to the top of the connecting ball 286 to move against the spring 284. Compression, aided by the compression of spring 284, allows the irregular block 282 to smoothly contact the inner wall of the groove. Once the irregular block 282 contacts the inner wall of the groove, the squeezing force on the connecting ball 286 disappears. At this time, due to the elastic restoring characteristic of spring 284, it will drive the moving circular plate 285 and the connecting ball 286 to return to their initial state. Finally, the middle position of the irregular block 282 and the bottom of the connecting ball 286 are in close contact, achieving a stable engagement between the irregular block 282 and the connecting ball 286. At this point, the entire information entry device is fully stored.

[0024] When operators need to temporarily place the device for other operations while inputting information in the field, they must first remove the bolts 35 located on the inner wall of the linkage block 34 and the threaded hole 33, which are used to fix the linkage block 34 and the telescopic column 32. Then, the support is pulled out, and the telescopic column 32 located inside the four corners of the bottom of the housing 1 is pulled out to the support height required by the operator. During this process, the telescopic circular plate 31 fixed at the top of the telescopic column 32 will slide in the groove opened inside the housing 1. Due to its structural design, the telescopic circular plate 31 is difficult to detach from the internal groove of the housing 1. This structure can limit the maximum length of the telescopic column 32 that it can move out of the housing 1, thus avoiding support When the device extends beyond its original position and faces uneven ground in the field, the adjustable telescopic column 32 can flexibly adapt to different height requirements at each support angle, ensuring that the device is placed stably. After adjusting to the required support height, the support height needs to be fixed. Therefore, the bolt 35 is reinserted into the threaded hole 33 of the linkage block 34, which is aligned with the height. The bolt 35 is used to fix the current support height of the telescopic column 32, ensuring the stability of the device. When the support shell 1 is no longer needed, simply remove the bolt 35 again, retract the telescopic column 32 into the shell 1, and finally reinstall the bolt 35 to complete the fixation, thus restoring the device to its portable state.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
