Description

Technical Field

[0001] The invention relates to the technical field of agriculture, in particular to a device for measuring the grain falling rate of old sibiricum. Background Art

[0002] For crops, if the grain shed tendency of crops is strong, although it is easy to thresh, the external forces such as natural wind or human activities will aggravate the grain shed of seeds in the mature period, causing crop harvest losses and affecting crop yields. On the contrary, if the grain shed tendency is weak, it will lead to difficulties in threshing seeds after harvesting and great waste. Therefore, accurate screening of crop varieties with moderate grain shed tendency is an important way to reduce yield losses from manual or mechanical harvesting. There is no unified standard for the determination of crop grain shed tendency. At present, the determination of grain shed tendency mainly includes the high-altitude dropping method, the artificial ear shaking method, the natural collection method, the dynamometer method, etc. The above traditional methods not only have many defects such as being greatly affected by human factors, poor accuracy and consistency, and cumbersome operation, but also require the stems of the crop plants to be cut off and brought back to the laboratory for testing, which has low detection efficiency. The Chinese patent announcement number is: CN112964836B discloses "Portable in-situ measurement device for crop grain shedding". In this patent, the grain receiving plate and the cover plate are both made of two semicircular structures that are hinged together, and the grain receiving plate and the cover plate are connected by a transparent film. Therefore, this device can be used to cover the entire plant or the part of the plant that needs to be measured, so as to isolate the plant to be measured from the outside world, thereby avoiding interference from factors such as wind and birds.

The device for measuring the grain falling rate of old sorghum, the lead screw slide rail drives the slide cylinder to move downward, the distance adjustment component is driven to slide downward, and the wrapping measurement mechanism wraps the old sorghum in the measurement area from top to bottom. In this process, the pressure on the awns can be minimized, which solves the problem of how to minimize damage to the measured and surrounding old sorghum when measuring the grain falling rate.

[0022] 2. The device for measuring the grain falling rate of old sorghum is driven to move to the position below the wheat ear. At this time, the wrapping and measuring mechanism completely wraps the wheat ear, and the telescopic cylinder drives the pulling rod to move obliquely downward.

[0023] 3. The device for measuring the grain drop rate of old sorghum, the bottom of the wheat ear is driven to move toward the center, and the grains of the wheat ear are driven to expand outward, the limit component is inside the steel cage, the limit component applies an upward pulling force to the middle position of the inner side of the tension component, and at the same time, the distance adjustment component drives the steel cage to move downward, the bottom of the tension component is in a downward concave state, and the tension component measures the weight of the dropped grains in real time, which solves the problem of how to measure the grain drop rate of old sorghum in real time to better judge the planting node.

[0024] 4. The device for measuring the grain drop rate of old sorghum has a steel cage structure that allows sunlight to pass through the polyethylene film, so that the ears, stems and leaves of the old sorghum can carry out normal photosynthesis, thereby avoiding the error in the grain drop rate caused by the old sorghum being unable to photosynthesize. The top plate is located above the steel cage, and rainwater cannot enter the interior of the polyethylene film, making the grain drop rate detection more accurate and the planting node judgment more accurate.

[0025] 5. The device for measuring the grain falling rate of old sorghum, when the steel cage moves down again, the plastic film tube can form a downward concave structure, and the grains of the wheat ears fall into the inside of the concave structure. At this time, the inner and outer sides of the plastic film tube are subjected to upward pulling force, and the friction-reducing coating can reduce the friction between the plastic film tube and the stems and leaves, thereby reducing the damage to the stems and leaves. The change in the pulling force on the plastic film tube can show the change in the weight of the fallen grains, thereby measuring the weight of the grains of old sorghum. The bottom extension design of the fixed ring can avoid the interference of rain and wind, making the grain falling rate measurement result more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The third embodiment: Figure 3 , Figure 6 As shown, the output end of the screw guide rail 51 is connected to a slide cylinder 53 through a thread, the bottom of the slide cylinder 53 is fixedly connected to a distance adjustment component 55, and the lower position of the surface of the distance adjustment component 55 is fixedly connected to a pulling component 56, the slide cylinder 53 is used to drive the wrapping measuring mechanism 7 to move downward, the pulling component 56 is used to pull the wrapping measuring mechanism 7 to wrap the wheat ears of old sibiricum, and the distance adjustment component 55 is used to change the structure of the wrapping measuring mechanism 7 so as to facilitate the acceptance and weight measurement of the fallen grains;

At this time, the electric cylinder 77 drives the pressure ring 78 to move downward to the lower position of the inner side of the tension component 73. The tension component 73 is pressed by the pressure ring 78 and is in an upright state. The tension component 73 passes through the wheat ears of old sorghum to the stems and leaves. At this time, the distance adjustment component 55 is at the lower position of the inner side of the screw rail 51, and the pulling component 56 pulls the bottom of the tension component 73 to make it constricted. The bottom of the tension component 73 constricts the stems and leaves of old sorghum in the sampling area.

The structure of the steel cage 71 allows sunlight to pass through the polyethylene film 72, so that the ears, stems and leaves of the old sorghum can carry out normal photosynthesis, avoiding the increase of the grain falling rate error caused by the inability of the old sorghum to photosynthesize. The top plate 74 is above the steel cage 71, and rainwater cannot enter the interior of the polyethylene film 72, making the grain falling rate detection more accurate and the planting node judgment more accurate.

There are two cloth bag rings 734.

[0055] When in use, the steel cage 71 is initially moved downward in order to wrap the wheat ears on the inner side of the plastic film tube 733.

Gas is introduced into the hollow cylinder 553, and the connection pipe 554 drives the distance between the bottom of the plastic film tube 733 and the bottom of the steel cage 71 to decrease. The steel cage 71 moves downward again, and the plastic film tube 733 can form a downward concave structure, and the grains of the wheat ears fall into the inside of the concave structure. At this time, the inner and outer sides of the plastic film tube 733 are subjected to upward pulling force, and the friction-reducing coating 735 can reduce the friction between the plastic film tube 733 and the stems and leaves, thereby reducing damage to the stems and leaves. The change in the pulling force on the plastic film tube 733 can show the change in the weight of the fallen grains, thereby measuring the weight of the grains of the old sorghum. The bottom extension design of the fixing ring 731 can avoid interference from rain and wind, making the grain drop rate measurement result more accurate.
