Description

Technical Field

[0001] The utility model relates to the technical field of watermelon planting, in particular to a device for identifying and removing young watermelon fruits. Background Art

[0002] During the watermelon planting process, if multiple watermelons are produced on one plant, a large amount of nutrients will be needed. If the soil fertility is insufficient, the growth of the watermelon will be weakened. When mature, the watermelon fruit will become smaller and the quality will deteriorate, failing to show the characteristics of the variety. Therefore, during the watermelon planting process, it is necessary to remove the young watermelon fruits that do not grow well, that is, select the watermelons and retain the young watermelon fruits that grow better, to ensure the quality of the watermelon after it matures.

[0003] At present, the identification and selection of watermelons completely rely on the experience of watermelon farmers. However, the error of naked eye judgment is large. Especially when the sizes of two young watermelon fruits are close, it is often difficult for watermelon farmers to accurately judge the weight of the young fruits, which leads to the farmers often mistakenly picking watermelons with better growth. In addition, after the young fruits are identified and selected, the watermelon farmers are unable to scientifically analyze the growth of the watermelons in the entire watermelon field, which is not conducive to scientific selection of watermelons and scientific management of watermelon fields, and the quality of watermelon planting is difficult to improve. In view of this, we propose a watermelon young fruit identification and removal device. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] During the growth of watermelons, if a watermelon seedling produces multiple young fruits, the young fruits will compete for nutrients, resulting in a decline in the quality of the watermelon. For this reason, it is necessary to screen the young fruits, remove the young fruits that grow poorly, and retain the young fruits that grow well, to ensure the quality of the watermelon after it matures. At present, this work completely relies on the experience of watermelon farmers to identify and screen, which is prone to misoperation and is not conducive to scientific watermelon cultivation.

[0037] See also Figure 1-Figure 10 , a technical solution provided by the utility model:

[0038] A device for identifying and removing young watermelon fruits comprises a base 1, a shearing mechanism 2 is provided on the base 1 for shearing watermelon vines, a placing shell 3 for placing young watermelon fruits is connected to the shearing mechanism 2, and a weighing mechanism 4 is provided on the base 1, and the weighing mechanism 4 is connected to the placing shell 3 for weighing young watermelon fruits. When in use, the young watermelon fruits are placed in the placing shell 3, the weight of the young watermelon fruits is weighed by the weighing mechanism 4, and the young watermelon fruits with unqualified weight are sheared by the shearing mechanism 2, and qualified young fruits are retained. In this process, since the weighing mechanism 4 is provided, the weight of the young watermelon fruits can be weighed, so that watermelon farmers can more scientifically identify the quality of the young fruits and retain the young fruits with the best growth potential.

[0039] Specifically, the shearing mechanism 2 in this embodiment includes a support frame 21, the bottom end of the support frame 21 is fixedly mounted on the base 1, and a first handle 22 is fixedly mounted on the support frame 21, which is used to pick up and support the watermelon young fruit identification and removal device. A first support plate 23 is fixedly mounted on the support frame 21, and the first support plate 23 is rotatably connected to a second support plate 25 through a rotating shaft 24, and one end of the second support plate 25 is fixedly connected to a second handle 28, and one end of the second handle 28 is fixedly mounted with an arc frame 27, and a blade 29 is fixedly mounted on the arc frame 27, which is used to cut the watermelon vine, and the second support plate 25 is elastically connected to the first support plate 23 through a torsion spring 26, so that a certain angle is maintained between the first handle 22 and the second handle 28, and then the arc frame 27 and the placement shell 3 are kept in an "open" state, so that the watermelon young fruit can enter the placement shell 3 conveniently. When it is necessary to cut the vine of the young watermelon fruit, the second handle 28 only needs to be rotated counterclockwise, so that the second handle 28 drives the blade 29 to rotate through the arc frame 27 to cut the vine. Further, a cutting seat 5 is fixedly installed on the placement shell 3, and a cutting groove is opened on the top of the cutting seat 5. The cutting seat 5 can support the vine. The blade 29 can enter the cutting groove after rotating a certain angle, and cut the vine in the process of entering, so that the cutting process is smoother.

[0040] In this embodiment, the weighing mechanism 4 includes a box body 41, the bottom of the box body 41 is fixedly mounted on the base 1, and a weighing device 42 is arranged on the box body 41, and the weighing device 42 is used to weigh the young watermelon fruits. The weighing device 42 is connected to an indicating device 43. When the weight of the young watermelon fruits reaches a certain value, the indicating device 43 will send a signal, indicating that the young fruits are qualified and can be retained, thereby making it more convenient for melon farmers to identify the young watermelon fruits.

[0041] Further, the weighing device 42 includes a sliding plate 421, which is slidably mounted on the inner wall of the box body 41, the bottom of the sliding plate 421 is elastically connected to the inner wall of the box body 41 through a support spring 425, the top of the sliding plate 421 is fixedly connected with a sleeve 422, the surface of the sleeve 422 is slidably connected to the inner wall of the box body 41, the top of the sleeve 422 penetrates the box body 41 and is fixedly connected with a connecting plate 423, the connecting plate 423 is fixedly connected with a connecting frame 424, and the top of the connecting frame 424 is fixedly connected to the placement shell 3. The support spring 425 can provide elastic force to support the sliding plate 421, and then support the placement shell 3, so that a certain distance is maintained between the placement shell 3 and the box body 41. When the placement shell 3 bears a certain weight, it will move downward and compress the support spring 425. When the weight in the placement shell 3 is reduced, it will automatically reset under the elastic force of the support spring 425. A fixing rod 426 is slidably connected to the inner wall of the sleeve 422, the bottom end of the fixing rod 426 is fixedly connected to the inner wall of the box body 41, and the surface of the fixing rod 426 is slidably connected to the inner wall of the sliding plate 421. The fixing rod 426 is used to limit the sleeve 422 and the sliding plate 421, so that the movement of the sleeve 422 and the sliding plate 421 is more stable.

[0042] Furthermore, a rack 427 is fixedly installed on one side of the sliding plate 421, and a gear 428 is meshed on the surface of the rack 427. A driving shaft 429 is fixedly installed at the axis of the gear 428. The driving shaft 429 is rotatably installed on the inner wall of the box body 41, and one end of the driving shaft 429 penetrates the box body 41 and is fixedly installed with a display pointer 4210. The surface of the box body 41 is provided with scale lines 4211, and the scale lines 4211 are distributed in a ring shape outside the display pointer 4210. When the sliding plate 421 moves downward, the gear 428 is driven to rotate through the rack 427, and the gear 428 drives the display pointer 4210 to rotate through the driving shaft 429. One end of the display pointer 4210 points to the scale line 4211, so that the weight of the young watermelon fruit placed in the shell 3 can be displayed, and the purpose of weighing can be achieved.

[0043] In this embodiment, the indicating device 43 includes an indicator light 431, which is fixedly mounted on the display pointer 4210. The positive and negative electrodes of the indicator light 431 are electrically connected to the first touch panel 432 and the second touch panel 433, respectively, and a power module (not shown in the figure) is connected to the circuit to provide power for the indicator light 431 to light up. A rotating plate 435 is fixedly connected to the first touch panel 432, and the rotating plate 435 is fixedly mounted on the drive shaft 429, so that the first touch panel 432 can rotate with the rotation of the drive shaft 429. When the first touch panel 432 rotates a certain angle, it can contact the second touch panel 433, so that the circuit is closed and the indicator light 431 lights up. An adjusting component 434 is connected to the second touch panel 433, which is used to adjust the position of the second touch panel 433, so that the device can indicate young fruits of different weights according to needs.

[0044] Specifically, the adjustment component 434 includes a rotating ring 4341, which is rotatably mounted on the inner wall of the box body 41, and an adjustment pointer 4348 is fixedly mounted on one end of the rotating ring 4341, and one end of the adjustment pointer 4348 points to the outside of the scale line 4211, which is used to indicate the position of the second touch plate 433. A groove is provided on the inner circumference of the rotating ring 4341, and an arc rod 4346 is fixedly mounted in the groove. The inner wall of the second touch plate 433 is slidably connected to the surface of the arc rod 4346, and one side of the second touch plate 433 is elastically connected to the inner wall of the groove through an arc spring 4347. The arc rod 4346 is used to support and limit the second touch plate 433, so that the second touch plate 433 can slide along the annular track. When the first touch panel 432 contacts the second touch panel 433, the indicator light 431 lights up, and then the first touch panel 432 continues to rotate to synchronously drive the second touch panel 433 to slide in the groove, and the first touch panel 432 and the second touch panel 433 maintain a state of continuous contact, and the indicator light 431 continues to light up without affecting the rotation of the display pointer 4210, so that the display pointer 4210 can display the final quality of the young watermelon fruit.

[0045] Furthermore, worm gear teeth 4342 are provided on the outer circumference of the rotating ring 4341, and a worm 4343 is meshed on the surface of the worm gear teeth 4342. The rotation of the rotating ring 4341 is controlled by the meshing of the worm 4343 and the worm gear teeth 4342, which can achieve the purpose of self-locking to a certain extent and prevent the adjustment pointer 4348 from moving randomly. A connecting shaft 4344 is fixedly installed on the top of the worm gear 4343, and the connecting shaft 4344 is rotatably installed on the inner wall of the box body 41, and the top of the connecting shaft 4344 passes through the box body 41 and is fixedly installed with a rotating handle 4345, which is convenient for manual control of the rotating handle 4345.

[0046] Working principle: Before the melon farmer uses the watermelon young fruit identification and removal device of the utility model to remove the watermelon young fruit, he first adjusts the position of the second touch plate 433 through the adjustment component 434. Assuming that during this screening, the weight of the watermelon young fruit is not less than X, that is, it is a qualified product, then the user can control the rotation of the worm 4343 by turning the handle 4345, and the worm 4343 drives the worm gear 4342 to rotate through meshing, and the worm gear 4342 synchronously drives the rotating ring 4341. On the one hand, the rotating ring 4341 drives the second touch plate 433 to rotate through the arc rod 4346 and the arc spring 4347, and on the other hand, the rotating ring 4341 directly drives the adjustment pointer 4348 to rotate, so that the adjustment pointer 4348 rotates synchronously with the second touch plate 433. When the adjustment pointer 4348 points to the X scale on the scale line 4211, it means that the adjustment is completed.

[0047] Then, the user holds the first handle 22 to move the device. When the device is moved to a suitable position, the young watermelon fruit to be screened is placed in the shell 3. The weight in the shell 3 increases, causing the shell 3 to move downward, and the sliding plate 421 is driven downward by the sleeve 422. The sliding plate 421 drives the gear 428 to rotate through the rack 427, and the gear 428 drives the display pointer 4210 to rotate through the driving shaft 429. One end of the display pointer 4210 points to the scale line 4211, so as to display the weight of the young watermelon fruit in the shell 3. When the driving shaft 429 rotates, it will synchronously drive the first touch plate 432 to rotate through the rotating plate 435. If the weight of the young watermelon fruit is less than X, the first touch plate 432 will not contact the second touch plate 433, and the indicator light 431 will not light up, indicating that the quality of the young fruit is unqualified and can be removed. When the weight of the young watermelon fruit reaches a certain value, the first touch plate 432 will contact the second touch plate 433, so that the circuit is closed and the indicator light 431 lights up, indicating that the quality of the young watermelon fruit is qualified.

[0048] Melon farmers can remove young fruits whose quality is less than X by rotating the second handle 28 counterclockwise so that the second handle 28 drives the blade 29 to rotate through the arc frame 27 to cut off the melon vine.

[0049] Sometimes, there are multiple young fruits on a melon vine with similar quality and none of them exceeding X or all exceeding X. At this time, the melon farmer can compare the quality of the young fruits through the display pointer 4210, select the young fruits with better quality, and remove the other young fruits. In addition, the quality of the young fruits can be recorded and analyzed, so as to manage the melon field more scientifically.
