DETAILED DESCRIPTION

[0029] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0030] like Figure 1-2 The figure shows the overall structure diagram of the corn sorting and detection system of the present invention. It includes a silo 100, a conveyor chain 200, and a guide rail. The silo 100 has multiple silos for placing unsorted and detected corn. Mounting columns 300 are fixedly provided at the four corner positions on both sides of the upper part of the silo 100. The guide rails are divided into a left guide rail 400 and a right guide rail 500. The left guide rail 400 and the right guide rail 500 are symmetrical groove-type guide rails. The middle parts of the left guide rail 400 and the right guide rail 500 both have running grooves. The silo 100 is mounted on the left guide rail 400 and the right guide rail 500 through four left and right mounting columns 300. The outer end of the mounting column 300 passes through the running grooves in the middle of the left guide rail 400 and the right guide rail 500 and is rotatably mounted at the link connection of the conveyor chain 200. A conveying chain 200 parallel to the left guide rail 400 and the right guide rail 500 is respectively arranged on the outside. The conveying chain 200 is driven by a sprocket driven by a motor. The movement of the conveying chain 200 further drives the transportation of the silo 100 to realize the transmission of corn.

[0031] The mounting column 300 includes a column body 301 and a roller 302. The roller 302 is rotatably mounted in the middle of the column body 301. The roller 302 is simultaneously rollingly arranged inside the running grooves of the left guide rail 400 and the right guide rail 500. A plurality of silos 100 are sequentially mounted on the guide rails and the conveyor chain 200 through the mounting column 300.

[0032] The present invention realizes the length detection and sorting of corn synchronously by tilting the silo. Figure 3 , 6 As shown, the left guide rail 400 includes a left horizontal section 400a and a left upwardly inclined section 400b, and the right guide rail 500 includes a right horizontal section 500a and a right downwardly inclined section 500b. The left horizontal section 400a and the right horizontal section 500a are located in correspondence with each other, and the left upwardly inclined section 400b and the right downwardly inclined section 500b are located in correspondence with each other. When the silo 100 is transported on the left horizontal section 400a and the right horizontal section 500a, the silo 100 is in a horizontal state, as shown in FIG. Figure 6 When the silo 100 runs to the left upward inclined section 400b and the right downward inclined section 500b, the silo 100 tilts toward the right.

[0033] The length detection position 10 and the discharge hopper 20 are located at the rear of the inclined section of the two guide rails. The discharge hopper 20 is arranged behind the length detection position 10 along the conveying direction of the silo 100. Through the inclination of the silo 100 and the detection of the length detection position 10, the corn that does not meet the length standard can be discharged to the discharge hopper 20 at the length detection position 10. Figure 4-5 The structure of the silo 100 will be described.

[0034] like Figure 4 As shown, the silo 100 includes a silo body 101, a discharge flap 102, a pusher 103, a locking pin 104, and a locking pin shaft 105. The discharge flap 102 is flippably arranged at the lower part of the silo body 101, and the pusher 103 is slidably arranged inside the silo body 101. The silo body 101 includes a left side plate 101a, a bearing plate 101b, and a right side plate 101c. The cross-section of the bearing plate 101b is in an open rectangular, semicircular, or other shape, and is used to accommodate corns. The length of the bearing plate 101b is approximately greater than the length of two corns. The left side plate 101a and the right side plate 101c are respectively arranged on the left and right sides of the bearing plate 101b to block the left and right sides of the bearing plate 101b. The left side plate 101a is close to the left guide rail 400, and the right side plate 101c is close to the right guide rail 500. A unloading opening is provided at the bottom of the carrier plate 101b near the right side plate 101c, and the length of the unloading opening is equal to half the length of the carrier plate 101b. The unloading flap 102 is rotatably set at the unloading opening position, and its shape matches the shape of the unloading opening. The unloading flap 102 includes a unloading plate body 102a and a hinged joint 102b. The shape of the unloading plate body 102a matches the shape of the unloading opening. One end of the unloading plate body 102a is rotatably connected to the carrier plate 101b through the hinged joint 102b, and the other end is a free end, which can be positioned or released by the locking pin 104. When the locking pin 104 positions the unloading flap 102, the unloading flap 102 closes the unloading opening, and the corn in the silo 100 will not be unloaded; when the locking pin 104 releases the unloading flap 102, the free end of the unloading plate body 102a rotates downward, the unloading flap 102 opens the unloading opening, and the corn in the silo 100 can be unloaded from the unloading opening.

[0035] A pusher 103 is slidably arranged inside the silo 100, and the pusher 103 includes a pusher plate 103a, a guide shaft 103b, and a counterweight 103c. The shape of the pusher plate 103a matches the shape of the internal cross-section of the silo 100. Under normal conditions (i.e., when the corn is just put into the silo and the silo is located on the guide rail of the horizontal section), one side of the pusher plate 103a is in close contact with the inner side of the left plate 101a, and the other side of the pusher plate 103 is fixedly connected with two guide shafts 103b. One end of the guide shaft 103b is fixedly connected to the pusher plate 103a, and the other end passes through the outside of the right plate 101c and is fixedly connected with the counterweight 103c. The right plate 101c is provided with a through hole 101d for passing the guide shaft 103b. Under normal conditions, one side of the counterweight 103c is in close contact with the outer side of the right plate 101c, that is, the length of the guide shaft 103b is approximately equal to the length of the silo 100. When the silo 100 runs to the inclined section, that is, the silo 100 runs to the left upward inclined section 400b and the right downward inclined section 500b, the silo 100 will produce the following Figure 6As shown in the inclination, the pushing piece 103 moves to the right under the action of the gravity of the counterweight 103c. During the movement, the pushing plate 103a simultaneously pushes the corn in the silo 100 to the right until the right end of the corn contacts the inner wall of the right plate 101c. At this time, the length of the counterweight 103c extending outward can reflect the length of the corn in the silo.

[0036] The locking pin 104 is rotatably set at the bottom of the right side plate 101c through the locking pin shaft 105. When the direction of the locking pin 104 is parallel to the length direction of the silo 100, one end of the locking pin 104 can position the free end of the unloading plate body 102a to prevent it from rotating downward, and the other end of the locking pin 104 extends outward from the outside of the right side plate 101c; when the locking pin 104 is rotated to be roughly perpendicular to the length direction of the silo 100, one end of the locking pin 104 releases the positioning of the unloading plate body 102a, and the other end also rotates to a position where it does not extend out of the right side plate 101c.

[0037] Combine the following Figure 3 , 7 -9 describes the length detection and unloading structure and method of the present invention.

[0038] like Figure 7 , Figure 8 and Fig. 9 As shown in FIG. 1 , when the silo 100 moves to the left upwardly inclined section 400b and the right downwardly inclined section 500b, the pusher 103 moves to the right under the gravity of the counterweight 103c, and the length of the counterweight 103c extending outward can reflect the length of the corn in the silo. Figure 3 The length detection position 10 shown in the figure specifically includes a controller 10a, an impeller 10b, an impeller shaft 10c, and a telescopic cylinder 10d. The controller 10a is a conventional single-chip microcomputer controller, the impeller 10b is fixedly arranged on the impeller shaft 10c, and the impeller shaft 10c can be rotatably arranged at the length detection position 10, so that the direction of the impeller shaft 10c is perpendicular to the moving plane of the forward movement of the silo 100 in the tilted state, and at the same time, the height position of the impeller 10b is equal to the height position of the counterweight 103c, and the distance between the edge of the impeller 10b and the right side plate 101c is L, and the distance L satisfies the following conditions: L=DS, where D is the silo length or the guide shaft length, and S is the corn screening length value. If the corn length is greater than S, it is considered that the corn is qualified and meets the detection requirements. If the corn length is less than S, it is considered that the corn is unqualified and does not meet the detection requirements and needs to be unloaded from the silo.

[0039] Corresponding to Figure 7 and Figure 8 Two states of Figure 7If the length S1 of the middle corn is less than S, the length of the counterweight 103c extending outward is greater than L. During the forward movement of the silo 100, the counterweight 103c pushes the impeller 10b to rotate; Figure 8 The length S2 of the middle corn is greater than S, and the length of the counterweight 103c extending outward is less than L. When the silo 100 moves forward, the counterweight 103c will not contact the impeller 10b, and the impeller 10b will not rotate.

[0040] When the impeller 10b rotates, the impeller shaft 10c is driven to rotate synchronously. A rotary encoder is set at the impeller shaft 10c to detect the rotation of the impeller 10b. The rotary encoder is connected to the controller 10a. The controller 10a detects the rotation of the impeller 10b through the rotary encoder. At the same time, the controller 10a is connected to the telescopic cylinder 10d. The telescopic cylinder 10d is a conventional electrically controlled telescopic structure, such as an electric telescopic rod, an electromagnetic telescopic rod, etc. Figure 7 As shown, when the impeller 10b is driven to rotate by the counterweight 103c, the controller 10a controls the telescopic cylinder 10d to extend based on the detection of the rotary encoder; Figure 8 When the impeller 10b does not contact the counterweight 103c, the controller 10a does not detect the data of the rotary encoder and controls the telescopic cylinder 10d to retract.

[0041] The telescopic cylinder 10d is fixedly arranged at the length detection position 10, specifically, arranged at a lower position relative to the right side plate 101c in the height direction. When the telescopic cylinder 10d is in the extended state, the end of the telescopic cylinder 10d can push the locking pin 104 to rotate; when the telescopic cylinder 10d is in the retracted state, the end of the telescopic cylinder 10d will not push the locking pin 104 to rotate.

[0042] like Figure 7 and Fig. 9 As shown, when the controller 10a controls the telescopic cylinder 10d to extend, during the forward movement of the silo 100, the locking pin 104 contacts the extended telescopic cylinder 10d, and the locking pin 104 is forced to rotate, and eventually the locking pin 104 loses its positioning on the unloading plate body 102a, and the unloading plate body 102a flips downward, thereby realizing the unloading of the corn inside the silo 100.

[0043] By means of the inclined guide rails, the setting of the pushing piece, the rotation of the impeller driven by the pushing piece, the extension and retraction of the telescopic cylinder controlled by the rotation of the impeller, and the extension and retraction of the telescopic cylinder, the corn in different silos can be unloaded, and the automatic length detection of the corn during the transmission process and the unloading of unqualified corn can be realized. In particular, the setting of the pushing piece and the setting of the impeller position enable the control of the unloading structure to be realized synchronously through the device while the length detection function is realized.
