[0041] Please refer to Figures 1 to 4 In a preferred embodiment of the present invention, an adjustable discharging device includes a discharging frame 100, a material guiding triangle plate 200, a supporting plate 300, a lifting and lowering adjustment mechanism 400 and a swinging mechanism 500.

[0042] One of the sharp corners of the guide triangle plate 200 is set upward, and the materials converge downward along the inclined side of the guide triangle plate 200. The guide triangle plate 200 is installed in the material unloading frame 100. The guide triangle plates 200 are arranged at intervals along the left and right directions. Adjacent guide triangle plates 200 form a first material passing gap 210 at the bottom to allow materials to pass through. Usually, the first material passing gap 210 is fixed and cannot be adjusted. It can be understood that the number of the first material passing gap 210 is one less than the number of the guide triangle plates 200.

[0043] The support plate 300 is disposed below the first material feeding gap 210, and the support plate 300 and the bottom of the material guiding triangle plate 200 form a second material feeding gap 310, and the material needs to pass through the second material feeding gap 310 before it can fall and be discharged. It can be understood that the number and position of the support plates 300 correspond to the first material feeding gap 210, that is, a support plate 300 is correspondingly disposed below each first material feeding gap 210.

[0044] The lifting and adjusting mechanism 400 is installed on the blanking frame 100 , and is connected to the supporting plate 300 , and is used to drive the supporting plate 300 to move up and down to adjust the spacing of the second material transfer gap 310 .

[0045] The swing mechanism 500 is installed on the unloading frame 100. The swing mechanism 500 is connected to the pallet 300 and is used to drive the pallet 300 to swing back and forth, so as to drive the material on the pallet 300 to pass through the second feeding gap 310. Usually, the material will accumulate on the pallet 300 and will not easily slip out of the second feeding gap 310. The pallet 300 reciprocates left and right, which can drive the granular material out of the second feeding gap 310. With the reciprocating motion, the material on the pallet 300 will gradually be squeezed to the edge and finally fall off. The continuous reciprocating motion of the pallet 300 can achieve continuous discharge.

[0046] The present invention provides an adjustable discharging device, through the second feeding gap 310 formed by the guide triangle plate 200 and the support plate 300, the spacing of the second feeding gap 310 can be adjusted through the cooperation of the lifting adjustment mechanism 400 and the swing mechanism 500, and the material on the support plate 300 can be driven to pass through the second feeding gap 310, thereby realizing adaptive grain discharge for crops of different particle sizes; the gap size can be adjusted according to crops of different particle sizes, thereby improving the adaptability of the grain discharge mechanism, and solving the problem that traditional grain discharge wheels are difficult to adapt to crops of different particle sizes. The crops can be oil tea fruits or other granular agricultural products.

[0047] Reference Figure 3 , Figure 5 and Figure 6 The lifting and lowering adjustment mechanism 400 includes a rotating shaft 410 rotatably mounted on the material unloading frame 100. The rotating shaft 410 is arranged in the space surrounded by the material guiding triangle plate 200, so as to prevent the rotating shaft 410 from interfering with the material unloading; a swing arm 420 which can rotate synchronously with the rotating shaft 410 is installed on the rotating shaft 410, and a connecting rod 430 is hinged at one end of the swing arm 420 away from the rotating shaft 410, and the connecting rod 430 is hinged at one end away from the swing arm 420 to the supporting plate 300, and the width of the supporting plate 300 is greater than the width of the first material passing gap 210. Figure 3As shown, the connecting rod 430 is in a vertical or nearly vertical state, at which time the rotating shaft 410 drives the swing arm 420 to rotate, and the most important thing is to change the height of the connecting rod 430 and the pallet 300. Although the pallet 300 will move to a certain extent in the width direction (left and right direction), since the width of the pallet 300 is greater than the width of the first feeding gap 210, within the range of motion of the pallet 300, even if the pallet 300 is driven by the swing arm 420 to have a certain displacement in the width direction, it will not affect the pallet 300 covering the first feeding gap 210 in the width direction, and will not affect the control of the blanking. Of course, in some other embodiments, the lifting and adjusting mechanism 400 can also be a telescopic motor to drive the pallet 300 to lift and lower.

[0048] Reference Figure 3 and Figure 5 In a further embodiment of the present invention, one end of the rotating shaft 410 passes through the side wall of the blanking frame 100 and is connected to a swing handle 440. The swing handle 440 rotates synchronously with the rotating shaft 410, so that the rotating shaft 410 can be driven to rotate by operating the swing handle 440 outside the blanking frame 100, so that the height dimension of the second feeding gap 310 can be adjusted by operating the rotating shaft 410.

[0049] Reference Figure 2 In a further embodiment of the present invention, a connecting seat 110 is provided on the outer side of the blanking frame 100 corresponding to the swing handle 440, and the connecting seat 110 is provided with two spaced-apart vertical blocks 111. The swing handle 440 is located between the two vertical blocks 111 and can swing between the two vertical blocks 111, thereby limiting the rotation range of the swing handle 440 and the rotating shaft 410. It can be understood that when the swing handle 440 swings between the two vertical blocks 111, the connecting rod 430 is always in a vertical or nearly vertical state, and the angle between the connecting rod 430 and the plumb line does not exceed 15 degrees, thereby reducing the horizontal displacement of the pallet 300 during the lifting activity.

[0050] Reference Figure 2In a further embodiment of the present invention, a limit bar 112 is provided at one end of the vertical block 111 away from the connecting seat 110, a swing handle 440 is located between the connecting seat 110 and the limit bar 112, a limit hole 441 is provided on the swing handle 440, and a surrounding perforation 113 is provided at the position of the limit bar 112 corresponding to the limit hole 441, the perforation 113 is arranged around the rotation axis, and the limit hole 441 selects one of the perforations 113 to align and penetrate the limit pin to achieve the fixation of the position and angle, and the limit hole 441 is aligned with different perforations 113, that is, corresponding to the second feeding gap 310 of different sizes, so that the spacing adjustment of the second feeding gap 310 is achieved by switching different perforations 113 to adapt to the feeding of crops of different particle sizes. It is usually not necessary to frequently adjust the size of the second feeding gap 310 in real time to adapt to different crops. Usually, before use, the limit hole 441 is aligned with the perforation 113 and the limit pin is penetrated to fix the second feeding gap 310 at a size to adapt to the crop particles that need to be faced. When it is necessary to change crops, the limit pin is pulled out again, the swing handle 440 is operated to rotate so that the limit hole 441 is aligned with the through hole 113 at another suitable position, and the limit pin is reinserted to adjust the spacing size of the second feeding gap 310.

[0051] like Fig. 9 and Fig.10As shown, in some other embodiments of the present invention, a plug post 600 is also included. An upper lifting plate 460 is connected to the swing handle 440 at intervals, and the upper lifting plate 460 is provided with a movable hole 461 aligned with the through hole 113, and the plug post 600 is movably inserted into the movable hole 461. One end of the plug post 600 is used to insert into the through hole 113, and the other end passes through the movable hole 461 and is installed with a nut 610. The peripheral wall of the plug post 600 is provided with a radial convex ring 620, and the radial convex ring 620 is located between the upper lifting plate 460 and the connecting seat 611. The plug post 600 is sleeved with a compression spring 630, and the two ends of the compression spring 630 are respectively against the radial convex ring 620 and the upper lifting plate 460, so as to apply a force toward the through hole 113 to the plug post 600, so that when there is no external force, the plug post 600 can remain in the state of being inserted into the through hole 113, so that the height of the support plate 300 and the spacing of the second material gap 310 remain stable. A pressing handle 700 is hinged on the upper lifting plate 460. A lifting portion 710 is provided at one end of the pressing handle 700, and an operating portion 720 is provided at the other end. The lifting portion 710 is provided with a U-shaped notch 711 for the insertion of the plug 600. The lifting portion 710 is located between the nut 610 and the upper lifting plate 460, so that when the operating portion 720 is pressed, the lifting portion 710 can lift the nut 610 and the plug 600 to make the plug 600 escape from the through hole 113. The contour of the nut 610 is larger than the movable hole 461, thereby preventing the plug 600 from escaping from the movable hole 461, and the outer peripheral contour of the nut 610 is larger than the plug 600, so that the lifting portion 710 can still contact the nut 610 after avoiding the plug 600, thereby driving the nut 610 and the plug 600 to be lifted. The plug 600 can be easily lifted by the pressing handle 700, and the operation is simple. When adjustment is required, hold the lifting plate 460 and press the operating part 720, and the lifting part 710 will lift the nut 610 and the column 600 to disengage the column 600 from the through hole 113. Then operate the lifting plate 460 to rotate around the rotating shaft 410 to align the column 600 with the through hole 113 at another suitable position, then release the operating part 720 and reinsert the column 600 into the aligned through hole 113 to achieve the spacing size adjustment of the second feeding gap 310 to meet different crop drying and feeding requirements.

[0052] Reference Figure 8 In a further embodiment of the present invention, the rotating shaft 410 extends in the front-to-back direction, and the front and rear side walls of the blanking frame 100 are provided with guide cylinders 120, and the rotating shaft 410 is rotatably mounted on the guide cylinders 120, thereby realizing the positioning and rotational guidance of the rotating shaft 410. In addition, in order to realize the axial positioning of the rotating shaft 410, the two ends of the rotating shaft 410 are threadedly connected with limit heads 450, and the outer peripheral contour of the limit head 450 is larger than the central hole of the guide cylinder 120.

[0053] Reference Figure 3 and Figure 7In a further embodiment of the present invention, the swing mechanism 500 includes a motor 510, an eccentric block 520 and a transmission rod 530. The output shaft of the motor 510 is connected to the eccentric block 520 to drive the eccentric block 520 to rotate. One end of the transmission rod 530 is hinged to the support plate 300, and the other end is hinged to the eccentric block 520. Thus, the rotation of the motor 510 drives the eccentric block 520 to rotate, and the transmission rod 530 finally drives the support plate 300 to move left and right. It can be understood that when the support plate 300 moves left and right, the transmission rod 530 will drive the support plate 300 to move up and down in a small range. The up and down movement is conducive to the smooth flow of materials from the second feeding gap 310, and the left and right movement of the support plate 300 is combined with a small up and down jump, so that the material flow and feeding are smoother.

[0054] Reference Figure 1 and Figure 3 In a further embodiment of the present invention, the number of the guide triangle plates 200 is greater than three, the pallets 300 are arranged one by one corresponding to the first material feeding gap 210, the adjacent pallets 300 can be connected by the serial rod 320 at the bottom, and the lifting and adjusting mechanism 400 and the swing mechanism 500 are both connected to the serial rod 320. Thus, the swing mechanism 500 and the lifting and adjusting mechanism 400 can drive multiple pallets 300 to move at the same time, reducing the number of driving mechanisms. Of course, in order to ensure sufficient power and convenient arrangement, the pallets 300 can be arranged in multiple groups, each group containing more than two adjacent pallets 300, the pallets 300 of the same group can be connected in series by the serial rod 320, and the pallets 300 of different groups are not connected, and the pallets 300 of different groups need to be provided with different lifting and adjusting mechanisms 400 and swing mechanisms 500. In addition, there can be multiple serial rods 320 corresponding to the pallets 300 of the same group, and the lifting and adjusting mechanism 400 and the swing mechanism 500 can be connected to the serial rods 320 at different positions.

[0055] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, a reinforcing rib plate 220 is installed in the material guide triangle plate 200, and the reinforcing rib plate 220 is in contact with a portion of the inner wall of the material guide triangle plate 200, thereby improving the structural strength of the material guide triangle plate 200 and reducing its deformation.

[0056] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, a vertical plate 230 extending vertically downward is provided at the bottom of the guide triangle plate 200, a positioning strip plate 240 is installed on the inner side of the vertical plate 230, the positioning strip plate 240 is provided with a positioning protrusion 241, and a positioning notch 221 adapted to the positioning protrusion 241 is provided on the bottom side of the reinforcing rib plate 220, so that the positioning of the reinforcing rib plate 220 is achieved by utilizing the cooperation of the positioning protrusion 241 and the positioning notch 221.
