Description

Technical Field

[0001] This utility model belongs to the field of crop measurement technology, specifically relating to a device for measuring the length of a single rice panicle. Background Technology

[0002] The length of the rice panicle is directly related to yield and is an important indicator for rice sowing. The panicle length is defined as the distance from the neck node to the tip (excluding the awn). Typically, the length of each rice panicle is measured manually before harvest. This process requires straightening the panicle, which can easily result in cuts from the panicle or leaves, and mature panicles are prone to grain loss. Furthermore, the lengthy measurement and observation process is labor-intensive and resource-intensive, and the results are easily affected by personal factors such as the fatigue level of the measurement personnel, leading to significant subjective errors.

[0003] In the existing process of measuring the length of a single rice panicle, the rice panicles are fluffy, requiring one person to manually gather them together while another person uses a measuring tape to measure the length of the gathered panicles. This process is time-consuming, labor-intensive, and has low measurement accuracy. Utility Model Content

[0013] Furthermore, the gathering bag is trumpet-shaped; the large opening end of the gathering bag is connected to the second limiting plate, and the small opening end passes through the first limiting plate and extends towards the end of the placement groove. The gathering bag is used to gather the rice in the placement groove.

[0014] Furthermore, the placement plate is provided with a positioning groove; the positioning groove is located at one end away from the sliding groove and is parallel to the placement groove.

[0015] Furthermore, the measuring component includes a laser rangefinder and a positioning block; the laser rangefinder is disposed on one end of the positioning groove near the first limiting plate; the positioning block is slidably disposed within the positioning groove.

[0016] Furthermore, a first groove is provided at one end of the placement plate near the first limiting plate; a fixing plate is rotatably connected to the placement plate; a second groove is provided on the fixing plate; the first groove and the second groove cooperate to fix the stem of the rice ear root.

[0017] Furthermore, a scale line is provided on one end of the placement plate near the positioning block.

[0018] Beneficial effects:

[0024] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0025] Example 1

[0026] Reference Figures 1 to 3 A device for measuring the length of a single rice panicle, comprising:

[0027] Placement board 2, with placement groove 1 on it for placing rice;

[0028] A limiting component is connected to the placement plate 2 to limit the rice in the placement trough 1;

[0029] Gathering bag 4 is placed in the placement slot 1 and connected to the limiting component to gather the wheat ears in the placement slot 1;

[0030] The measuring component is connected to the placement plate 2 and is set in a corresponding manner to the placement trough 1 to measure the panicle length of rice in the placement trough 1.

[0031] In this embodiment, the placement plate 2 is provided with two sliding grooves 12; the two sliding grooves 12 are respectively provided at both ends of the width direction of the placement groove 1, and the sliding grooves 12 extend along the length direction of the placement.

[0032] In this embodiment, the limiting component includes a first limiting plate 5 and a second limiting plate 3; the first limiting plate 5 is disposed on the placement plate 2, and both ends of the first limiting plate 5 are respectively disposed in two sliding grooves 12; the second limiting plate 3 is disposed on the placement plate 2 at one end away from the first limiting plate 5, and both ends of the second limiting plate 3 are respectively slidably disposed in two sliding grooves 12.

[0033] In this embodiment, both the first limiting plate 5 and the second limiting plate 3 are arched structures.

[0034] In this embodiment, the gathering bag 4 is trumpet-shaped; the large opening end of the gathering bag 4 is connected to the second limiting plate 3, and the small opening end passes through the first limiting plate 5 and extends to the end of the placement groove 1. The gathering bag 4 is used to gather the rice in the placement groove 1.

[0035] Among them, the gathering bag 4 has a small-angle end, which fits the shape of the ear tip better and prevents the ear tip from curling up during measurement.

[0036] The large opening end of the collection bag 4 is detachably connected to the second limiting plate 3, and the small opening end of the collection bag 4 is detachably connected to the first limiting plate 5. Preferably, a magnetic snap fastener is used to achieve quick disassembly, so that the bag can be quickly disassembled to clean and collect residual grains after measurement.

[0037] Among them, the collection bag 4 is made of transparent material, which makes it easy to observe the placement of rice ears inside the collection bag.

[0038] In this embodiment, the placement plate 2 is provided with a positioning groove 10; the positioning groove 10 is located at the end away from the sliding groove 12 and is parallel to the placement groove 1.

[0039] In this embodiment, the measuring components include a laser rangefinder 9 and a positioning block 11; the laser rangefinder 9 is disposed on the positioning groove 10 near one end of the first limiting plate 5; the positioning block 11 is slidably disposed in the positioning groove 10.

[0040] In this embodiment, a first groove 8 is provided on the placement plate 2 near the first limiting plate 5; a fixing plate 6 is rotatably connected to the placement plate 2; a second groove 7 is provided on the fixing plate 6; the first groove 8 and the second groove 7 cooperate to fix the stem of the rice ear root.

[0041] In this embodiment, a scale line is provided on the end of the placement plate 2 near the positioning block 11.

[0042] Through the above technical solution, the rice stalk passes through the second limiting plate 3 from the large opening end of the gathering bag 4 and then emerges from the small opening end of the gathering bag 4 on the first limiting plate 5, so that the connection between the stalk and the rice panicle is placed on the first groove 8 of the placement plate 2. The fixing plate 6 is fastened to fix the connection between the first groove 8 and the second groove 7. The position of the sliding positioning block 11 is adjusted so that the end face of the positioning block 11 away from the laser rangefinder 9 is flush with the top of the rice panicle. At this time, the distance between the positioning block 11 and the laser rangefinder 9 is measured by the laser rangefinder 9, and the value on the display screen of the laser rangefinder 9 is read. This value is the length of the rice panicle. At the same time, the position of the positioning block 11 can be measured a second time through the scale line to ensure the accuracy of the measurement. After the measurement is completed, the fixing plate 6 is opened, and the rice stalk is held by hand to pull the rice out from the small opening end of the gathering bag 4. This method does not damage the rice panicle and can accurately measure the length of the rice panicle.

[0043] The above are merely preferred embodiments of the present utility model and do not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
