Detailed Description of the Invention

[0028] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] As Figures 1 to 8 shown, the rapid determination device for the thousand-grain weight of seeds according to the present application includes a base 1. A plurality of inclined columns 2 are fixedly connected to the upper surface of the base 1. A seed input cavity 3 is fixedly connected to the upper surfaces of the inclined columns 2 together. As Figure 2 shown, the seed input cavity 3 includes a fixed circular cavity 101. A rotating groove 102 is opened inside the fixed circular cavity 101. As Figure 5 shown, a sliding ring 103 is rotatably connected inside the rotating groove 102. A debris screening cavity 104 is fixedly connected to the front surface of the sliding ring 103. A plurality of seed leakage holes 105 are opened on the inner side wall of the debris screening cavity 104. As Figure 3 shown, a rotating column 123 is fixedly connected to the front surface of the debris screening cavity 104. A motor 106 is fixedly connected to the front surface of the fixed circular cavity 101. The output end of the motor 106 penetrates through the rear end to the inside of the fixed circular cavity 101 and is fixedly connected to the front end of the rotating column 123. A discharge port 124 is opened on the lower surface inside the fixed circular cavity 101. A grain counting cavity 107 is fixedly connected to the lower surface of the discharge port 124.

[0031] When it is necessary to measure the thousand-grain weight of seeds, the seeds to be measured for the thousand-grain weight are put into the fixed circular cavity 101 in the seed input cavity 3. At this time, the debris screening cavity 104 is connected to the rotating groove 102 of the fixed circular cavity 101 through the sliding ring 103 and is in the initial position at this time. The motor 106 is started. The output end of the motor 106 drives the rotating column 123 to rotate, and then the debris screening cavity 104 fixedly connected to the rotating column 123 starts to rotate. During the rotation process, the seeds and possible mixed debris continuously roll in the debris screening cavity 104. Since a plurality of seed leakage holes 105 are opened on the inner side wall of the debris screening cavity 104, the seeds of appropriate size will be screened out through the seed leakage holes 105, and the debris remains in the debris screening cavity 104. After the seeds are screened for debris, due to the action of gravity, they will enter the grain counting cavity 107 through the discharge port 124 opened on the lower surface inside the fixed circular cavity 101. After the seeds enter the grain counting cavity 107, the passing seeds can be accurately counted.

[0032] As Figure 6 shown, a feed groove 108 is opened on the upper surface of the grain counting cavity 107. A dust leakage groove 109 is opened on the rear surface inside the feed groove 108. A dust leakage inclined plate 110 is opened on the front surface of the dust leakage groove 109. An ash outlet 111 is opened on the rear surface inside the dust leakage groove 109.Figure 7 As shown, a plurality of grain grooves 112 are provided below the inner side wall of the feeding groove 108. A laser sensor 113 is provided on the inner lower surface of the plurality of grain grooves 112. A light outlet 125 is provided on the inner front surface of the plurality of grain grooves 112. A gas pump 114 is fixedly connected to the inner lower surface of the plurality of grain grooves 112, behind the laser sensor 113. An extrusion chamber 115 is fixedly connected above the gas pump 114 inside the plurality of grain grooves 112. A sliding plate 116 is slidably connected inside the extrusion chamber 115. A long plate 117 is fixedly connected to the front surface of the sliding plate 116. An outlet plate opening 118 is provided on the inner front surface of the plurality of grain grooves 112. The long plate 117 is slidably connected to the outlet plate opening 118. A spring 119 is fixedly connected between the front surface of the sliding plate 116 and the inner front surface of the extrusion chamber 115.

[0033] The seeds screened by the sundry screening chamber fall into the feeding groove 108 of the grain counting chamber 107 through the discharge port 124. When the seeds enter the feeding groove 108, due to the existence of the ash leakage inclined plate 110, the seeds are initially separated from the dust during the falling process. The lighter dust will be driven to move towards the ash leakage groove 109. After the dust enters the ash leakage groove 109, it is discharged from the device through the ash outlet 111, thereby realizing the separation of the seeds and the dust and ensuring the accuracy of subsequent grain counting. The seeds continue to fall from the feeding groove 108 to the plurality of grain grooves 112 below the inner side wall. The laser sensor 113 emits laser through the light outlet 125. When the seeds fall into the plurality of grain grooves 112, the laser will be blocked. The laser sensor 113 counts the seeds according to the number of times the laser is blocked. When the number of blockages reaches a thousand, the gas pump 114 is started, so that the sliding plate 116 is under pressure. The sliding plate 116 will slide inside the extrusion chamber 115. The sliding plate 116 drives the long plate 117 to move forward. The long plate 117 extends into the plurality of grain grooves 112 through the outlet plate opening 118 and blocks the inside of the plurality of grain grooves 112, so that the seeds cannot continue to fall, making the measured quantity more accurate. When a measurement is completed, the device is turned off. When the pressure of the gas pump 114 disappears, the spring 119 will pull the sliding plate 116 back to its original position, and the long plate 117 will also retract into the plurality of grain grooves 112.

[0034] As Figure 1 and Figure 8 shown, a weighing chamber 4 is fixedly connected to the lower surface of the base 1. The grain counting chamber 107 is fixedly communicated with the weighing chamber 4. A high-precision weighing scale 5 is fixedly connected inside the weighing chamber 4. A wedge-shaped holding groove 6 is fixedly connected to the upper surface of the high-precision weighing scale 5. A weight display 7 is fixedly connected to the upper surface on the right side of the base 1. An extraction opening 8 is provided on the front surface of the weighing chamber 4. A baffle 9 is rotatably connected to the front surface of the weighing chamber 4 in front of the extraction opening 8 through a hinge.

[0035] After the seeds are counted by the seed counting chute 112, they fall into the weighing chamber 4 fixedly connected to the seed counting chamber 107. After the seeds enter the weighing chamber 4, they fall into the wedge-shaped holding chute 6 on the upper surface of the high-precision balance 5. The set wedge-shaped holding chute 6 causes the seeds to gather towards the middle when falling into it. When the selected seeds are successively dropped onto the high-precision balance 5, the high-precision balance 5 can accurately weigh the seeds and transmit the weight data to the weight display 7. The weight display 7 receives the weight data transmitted by the high-precision balance 5 and displays it, facilitating the user to read. When it is necessary to take out the seeds for further operations or clean the device, open the baffle 9 rotatably connected by a hinge in front of the outlet 8 on the front surface of the weighing chamber 4, and take out the seeds and the wedge-shaped holding chute 6 from the outlet 8 for processing.

[0036] As Figure 4 shown, a feeding port 120 is formed on the rear surface of the fixed circular chamber 101. A shutter 121 is rotatably connected by a hinge behind the feeding port 120 on the rear surface of the fixed circular chamber 101. A transparent glass 122 is fixedly connected to the outer side wall of the shutter 121.

[0037] Open the shutter 121 rotatably connected by a hinge behind the feeding port 120 on the rear surface of the fixed circular chamber 101, and the seeds to be measured for the thousand-grain weight can be put into the fixed circular chamber 101 from the feeding port 120 to prepare for subsequent operations such as screening impurities. During the operation of the device, the user can observe the impurity screening situation of the seeds inside the fixed circular chamber 101 through the transparent glass 122 fixedly connected to the outer side wall of the shutter 121, so as to timely understand the operation state of the device and judge whether adjustment or intervention is needed.

[0038] As Figure 1 shown, a plurality of support columns 10 are symmetrically and fixedly connected to the lower surface of the base 1; the plurality of support columns 10 are symmetrically distributed on the lower surface of the base 1, mainly playing the role of stably supporting the entire measuring device. They raise the whole device, forming a certain space between it and the placement plane, which is convenient for operation and observation. At the same time, the symmetrically distributed support columns 10 can ensure that the device remains balanced when placed, preventing it from tilting or shaking due to unstable center of gravity, and ensuring the stability and accuracy of the measurement process.

[0039] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
