The thickness sorting of bamboo tubes was mainly done manually at first. The Chinese utility model patent with publication number CN208373603U discloses an automatic bamboo sorting device, which discloses that the material-pickup mechanism is a chain sprocket structure, and the sorting mechanism is a cylinder driving the rotating shaft and the sorting steel bar to rotate. The sorting steel bar is located below the chain sprocket. When the sorting steel bar is in a horizontal state, the bamboo tube can pass through. When the sorting steel bar is in a vertical state, the bamboo tube falls into the storage trough. From the attachment of the above utility model patent Figure 1 It can be seen that the driving frames on the material-shifting chain are distributed one on the left and one on the right. The bamboo tubes are driven forward by the driving frames at the layer where the chain sprocket is located and the layer where the sorting steel bars are located. At the layer where the sorting steel bars are located, multiple sorting steel bars are arranged closely and in parallel, so that each time all the sorting steel bars rotate into place, the bamboo tubes can enter the layer where the sorting mechanism is located, that is, the distance between adjacent sorted bamboo tubes is equal to the width of the chain after installation. Each material-shifting chain can only drive two bamboo tubes in one rotation, resulting in low operating efficiency of the whole machine. In addition, in the above-mentioned utility model patent, the bamboo tubes are transferred from the material-shifting chain to the sorting storage assembly through the loading assembly, and the structure is relatively complicated.

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figure 1 to Figure 2 , the embodiments provided by the utility model are:

[0024] A bamboo tube and bamboo chip sorting machine comprises a frame 1, wherein the frame 1 comprises a double-layer frame, wherein the double-layer frame comprises an upper frame 12 and a lower frame 13, and further comprises a conveying mechanism 2 and a blanking mechanism 3, wherein the conveying mechanism 2 is fixed on the upper frame 12 and is used for conveying bamboo tubes and bamboo chips, and the blanking mechanism 3 is fixed on the lower frame 13 and is used for classifying, blanking and storing the bamboo tubes and bamboo chips.

[0025] The conveying mechanism 2 includes two chain drive assemblies 21 and a material clamping assembly 26 arranged side by side. A plurality of material clamping assemblies 26 are equidistantly installed on each chain drive assembly 21. The material clamping assembly 26 is used to place a single bamboo tube or bamboo piece. The number and position of the material clamping assemblies 26 on the two chain drive assemblies 21 correspond, which is equivalent to using two chain drive assemblies 21 to jointly convey the bamboo tubes or bamboo pieces in the conveying mechanism 2.

[0026] The blanking mechanism 3 includes at least two blanking components 31 and horizontal support rods 34 arranged at equal intervals. Each of the blanking components 31 includes a blanking gear rod 32 and a blanking cylinder 33. The spacing between adjacent blanking gear rods 32 is equal, and the spacing between adjacent blanking gear rods 32 is equal to the spacing between adjacent clamping components 26. The horizontal support rods 34 are in two opposite rows and are arranged in a direction parallel to the chain drive component 21. The horizontal support rods 34 are evenly arranged between adjacent blanking gear rods 32 and between the blanking gear rods 32 and the edge of the lower shelf 13. When the bamboo tubes and bamboo slices move to the position of the horizontal support rod 34, the blanking cylinder 33 has time to act. At this time, the blanking cylinder 33 controls the blanking gear rod 32 to a horizontal state or a downward flipping state. Therefore, the action of each blanking cylinder 33 in the sorting machine can be independently controlled, thereby reducing the spacing between adjacent bamboo tubes and bamboo slices and improving the equipment operation efficiency. Specifically, each of the blanking gear rods 32 is driven by a blanking cylinder 33 to perform a flipping motion. When the blanking cylinder 33 drives the blanking gear rod 32 to flip to a horizontal state, the upper surface of the blanking gear rod 32 is flush with the upper surface of the horizontal support rod 34. When the blanking cylinder 33 drives the blanking gear rod 32 to flip downward, the bamboo tubes and bamboo slices can slide down along the blanking gear rod 32 to achieve a one-time sorting of the bamboo tubes or bamboo slices.

[0027] In the blanking mechanism 3, the clamping assembly 26 fixed on the chain drive assembly 21 drives the bamboo tube and bamboo slice forward, and the bamboo tube and bamboo slice move forward above the two rows of horizontal support rods 34. When the bamboo tube and bamboo slice reach the top of the blanking assembly 31, if the thickness of the bamboo tube and bamboo slice belongs to the range of the blanking assembly 31, the blanking cylinder 33 drives the blanking stop rod 32 to flip downward, and the bamboo tube and bamboo slice fall; if the thickness of the bamboo tube and bamboo slice does not belong to the range of the blanking assembly 31, the blanking cylinder 33 drives the blanking stop rod 32 to flip upward to a horizontal state, so that the bamboo tube and bamboo slice can pass through. Since the action of each blanking assembly 31 can be independently controlled, and when the bamboo tube and bamboo slice run to the position of the horizontal support rod 34, the action of the blanking cylinder 33 can be controlled, that is, when the chain drive assembly 21 runs at a uniform speed, the action of the blanking cylinder 33 can be flexibly controlled, so that each blanking cylinder 33 can be independently operated, and the bamboo tube and bamboo slice corresponding to each clamping assembly 26 can be independently sorted. Each blanking mechanism 3 can sort out bamboo tubes and bamboo pieces of at least two kinds of thickness at one time, and each chain transmission assembly 21 can sort out at least four bamboo tubes and bamboo pieces per rotation, so the mechanical operation efficiency is high.

[0028] Furthermore, in order to allow the bamboo tubes and bamboo slices to be smoothly transferred from the conveying mechanism 2 to the material dropping mechanism 3, a material receiving rod 4 is also included, and the material receiving rod 4 includes a horizontal section 41 and an arc section 42. Each row of the horizontal support rods 34 is fixedly connected to one end of the horizontal section 41 at the end opposite to the outlet of the chain drive assembly 21. The upper surface of the horizontal section 41 is flush with the upper surface of the horizontal support rod 34. The other end of the horizontal section 41 is integrally connected to the arc section 42. The opening of the arc section 42 is opposite to the outlet of the material clamping assembly 26. Specifically, one end of the horizontal section 41 here refers to the end of the horizontal section 41 close to the horizontal support rod 34. The upper end of the arc section 42 is flush with the height of the material clamping assembly 26 in a vertical state, or higher than the height of the material clamping assembly 26 in a vertical state. Figure 1 In the direction shown, the right end of the arc segment 42 is located at or further to the right than when the clamping assembly 26 is turned down to the horizontal state, so that the bamboo tube and bamboo piece turned from the clamping assembly 26 are received by the arc segment 42, and are further pushed by the clamping assembly 26 on the horizontal segment 41 and on the blanking mechanism 3. This structure ingeniously realizes the docking problem of the conveying mechanism 2 and the blanking mechanism 3 regarding the bamboo tube and bamboo piece.

[0029] Specifically, the chain transmission assembly 21 includes a driving sprocket 22, a driven sprocket 23 and a chain 24, one chain 24 is meshed on a driving sprocket 22 and a driven sprocket 23, the conveying mechanism 2 also includes a driving motor and a driving shaft 25, the output end of the driving motor is fixedly connected to the driving shaft 25, and the two driving sprockets 22 are fixed on the driving shaft 25. The two rows of chain transmission assemblies 21 are connected through the driving shaft 25 and driven to rotate synchronously by the driving motor.

[0030] Specifically, regarding the structure of the clamping assembly 26, the clamping assembly 26 includes a pair of clamping rods 27, and the clamping rods 27 are vertically fixed on the chain 24. The distance between each pair of the clamping rods 27 is greater than the diameter of the selected object. The selected object here refers to bamboo tubes or bamboo slices, and the clamping rods 27 arranged in pairs are used to clamp the bamboo tubes and bamboo slices.

[0031] Further, regarding the specific structure of the blanking assembly 31, one end of the blanking stopper rod 32 is rotatably connected to the end of the horizontal support rod 34, and the bottom of the other end is rotatably connected to the telescopic end of the blanking cylinder 33, and the fixed end of the blanking cylinder 33 is rotatably connected to the lower shelf 13. The blanking cylinder 33 drives the blanking stopper rod 32 to flip, and the blanking cylinder 33 is located below the blanking stopper rod 32 as a whole, and does not affect the movement of the bamboo tube and bamboo slices.

[0032] Furthermore, the material-dropping stopper 32 is an I-shaped structure, one end of which is simultaneously connected to the end rotation rods of the two rows of oppositely arranged horizontal support rods 34, and the telescopic end of the material-dropping cylinder 33 is rotationally connected to the bottom of the middle part of the material-dropping stopper 32. An I-shaped material-dropping stopper 32 can achieve good support for the bamboo tubes and bamboo pieces, and prevent the bamboo tubes and bamboo pieces from being deflected during the transmission process.

[0033] Furthermore, a thickness detection sensor is also included, and the thickness detection sensor is fixed on the upper frame 12. The thickness of the bamboo tubes and bamboo pieces can be detected by the thickness detection sensor during the transmission process of the chain transmission component 21, so that when the bamboo tubes and bamboo pieces reach the blanking mechanism 3, they can be quickly selected by the blanking component 31.

[0034] Furthermore, the blanking mechanism 3 also includes a collection box, the frame 1 also includes a vertical support rod 11, the double-layer shelf is fixed above the vertical support rod 11, and a collection box is arranged below each blanking stop rod 32, and the collection box is also placed below the double-layer shelf.

[0035] Combination Figure 1 The working process of the bamboo tube and bamboo chip sorting machine is as follows: a bamboo tube or bamboo chip is placed manually, a bamboo tube or bamboo chip is placed on the card component 26, and the bamboo tube or bamboo chip is placed according to the card component 26. Figure 1 In the direction of the chain transmission rod assembly, the bamboo tube or bamboo piece on the clamping assembly 26 is transmitted from left to right, during which the thickness detection sensor detects the thickness of the bamboo tube or bamboo piece. When the bamboo tube or bamboo piece reaches the exit of the chain transmission assembly 21, when the clamping rod 27 of a clamping assembly 26 located in the front of the movement direction swings downward first, the bamboo tube or bamboo piece will fall on the receiving rod 4. When the clamping rod 27 of the clamping assembly 26 located in the rear of the movement direction swings downward, the clamping rod 27 drives the bamboo tube or bamboo piece on the receiving rod 4 to continue to move from right to left in the blanking mechanism 3, and the bamboo tube or bamboo piece first reaches the horizontal support rod 34 located on the far right in the blanking mechanism 3. At this time, the analysis and judgment is started to determine whether the bamboo tube or bamboo piece meets the thickness range of the blanking component 31 that is about to arrive. If it meets the range, the blanking cylinder 33 drives the blanking stop rod 32 to flip downward in the blanking component 31 that is about to arrive. When the bamboo tube or bamboo piece reaches the blanking component 31, it falls into the collection box below the blanking component 31; if the bamboo tube or bamboo piece driven by the clamping component 26 does not fall into the collection box below the blanking component 31, the analysis and judgment is started every time the next blanking component 31 is passed until the bamboo tube or bamboo piece falls into the collection box, and the analysis and judgment will no longer be started for the bamboo tube or bamboo piece transmitted by the clamping component 26. In summary, for each bamboo tube or bamboo piece transmitted by the clamping component 26, the thickness is judged during the conveying process of the chain transmission component 21, and the thickness is sorted in the blanking mechanism 3 until the bamboo tube or bamboo piece falls into the collection box. The sorting of each bamboo tube or bamboo piece does not conflict or interfere with the sorting actions of other bamboo tubes or bamboo pieces, and can be judged independently, thereby improving the efficiency of the automatic operation of the equipment.

[0036] In summary, the bamboo tube and bamboo chip sorting machine provided by the utility model shortens the distance between adjacent bamboo tubes or bamboo chips, so that the chain drive assembly 21 can sort at least four bamboo tubes or bamboo chips per rotation, greatly improving the efficiency of automatic sorting of bamboo tubes or bamboo chips, and cleverly realizes the transfer of bamboo tubes or bamboo chips from the upper chain drive assembly 21 to the lower blanking assembly 31 by using the receiving rod 4, and the structure is simple and reliable.
