Description

Technical Field

[0001] The present invention relates to the technical field of rice threshing equipment, and particularly relates to a breeding threshing machine for cultivating japonica rice germplasm resources in a laboratory. Background Art

[0002] Germplasm resources, also known as genetic resources, refer to the genetic material passed from the parent generation to the offspring generation of organisms. During the process of cultivating and researching rice germplasm resources, researchers usually need to judge the morphological characteristics of rice, including the plant morphology and grain characteristics of rice. Therefore, researchers often need to repeatedly sample rice plants from experimental fields, perform single-ear threshing on them, and count the number of filled grains and empty grains of single-ear rice.

[0003] However, most of the existing rice threshing equipment is large or medium-sized rice threshing equipment, which is generally used in scenarios of batch threshing of multi-ear rice. For example, a Chinese utility model patent with the authorization announcement number: CN219844116U discloses a rice breeding threshing machine, mainly including a support frame in a shape of a Chinese character "hui", a threshing roller rotatably inserted between the inner walls of the support frame through a rotating shaft for threshing rice. An installation frame is slidably arranged above the support frame, a guide rail is fixedly connected to the side wall of the support frame, both ends of the installation frame are slidably arranged inside the guide rail, a connecting bar is fixedly connected between the inner walls of the installation frame, and a pressing assembly for fixing rice is arranged on the installation frame. In this utility model, by using the installation frame, the connecting bar and the pressing assembly, the rice can be fixed, so that during the threshing process, there is no need to hold the rice by hand, reducing the risk of hand contact with the rice and improving the safety performance of the equipment. When specifically fixing, only need to place one end of the rice on the connecting bar, and then press and fix the rice through the pressing assembly.

[0004] This equipment mainly drives the threshing roller to rotate and contacts the rice with the threshing roller to achieve the rice threshing operation, and the effect of threshing single-ear rice is poor. Summary of the Invention

Then, the user fastens the box cover 212 of the containing box 21, and uses several elastic bands 248 to press and position the rice plants, and at the same time uses the fastening assembly to lock the box cover 212 and the box body 211 of the containing box 21; next, the user hangs several single-ear threshing modules 2 on the movable bracket 12 of the supporting bracket 1, and ensures that the several positioning holes 26 of each single-ear threshing module 2 are respectively plugged into the positioning plug 27 fixedly provided on the movable bracket 12, and then the user closes a pair of limiting brackets 14 to limit the single-ear threshing module 2 in the cavity enclosed by the movable bracket 12, the fixed bracket 11 and the limiting bracket 14. ; After that, the user inserts the pins 152 of a pair of locking assemblies 15 into the lock holes, thereby locking a pair of limit brackets 14 and the fixed bracket 11; next, the linear module 13 drives the movable bracket 12 to drive a number of single-ear threshing modules 2 and the driving module 3 to synchronously descend a certain distance, so that the bottom of the bottom end covers 22 of the single-ear threshing modules 2 abuts against the top of the base 112 of the fixed bracket 11, and then, the driving motor 32 drives the execution roller 31 to rotate a certain angle, and uses the execution roller 31 to squeeze the carrying plate 253, so that it moves a certain distance toward the accommodating box 21, so that the positioning block 28 is disengaged from the positioning slot and contacts the lock on the bottom end cover 22; then, the linear module 13 drives the movable bracket 12 to drive a number of single-ear threshing modules 2 and the driving module 3 to rise and reset, so that the accommodating box 21 of each single-ear separation module is separated from the bottom end cover 22.

[0094] When the equipment is running, the driving motor 32 drives the execution roller 31 to rotate, and then uses the execution roller 31 to continuously squeeze the supporting plate 253, driving the multiple guide rods 254 and multiple impact heads 255 arranged on the supporting plate 253 to cooperate with the pad 251 to continuously clamp the rice ears of the rice plants, so that the grains of the rice plants fall off, and the fallen grains finally fall through the bottom port of the accommodating box 21 into the bottom end cover 22 corresponding to the bottom position of the accommodating box 21, thereby completing the single ear threshing of the rice plants.

[0095] Above, refer to Figures 1 to 15 The present invention describes a laboratory breeding thresher for cultivating japonica rice germplasm resources, which has the following beneficial effects:

[0096] 1.

[0097] 2. The device is provided with a plurality of single-ear threshing modules 2 to fix and thresh a plurality of rice plants respectively. The grains separated from the rice plants can fall into the inner cavity of the bottom end cover 22 matched therewith through the bottom port of the accommodating box 21, so that the user can count the number of solid grains and the number of unsaturated grains of each rice plant, thereby enhancing the convenience of use of the device.

[0098] 3. The single ear threshing module 2 of the present device adopts a storage box 21 to store rice plants, thereby providing a better storage environment for the rice plants, so that subsequent users can observe and judge the morphological characteristics of the rice plants when conducting research on rice germplasm resource cultivation.

[0099] 4. The device uses the limiting lining 23, the elastic band 248 and the adjusting knob 247 to press and fix the rice plants, thereby improving the placement stability of the rice during the process of threshing a single ear of the rice plants, and further improving the rice threshing effect of the device.
