DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] The utility model provides a technical solution: a pumpkin seed drying device, such as Figure 1 As shown, it includes a drying box 101, which is used to hold pumpkin seeds. A screen 102 is fixed at the bottom of the drying box 101, and the screen 102 can prevent the pumpkin seeds from passing through. Vibration mechanisms 200 are arranged on both sides of the drying box 101.
[0033] like Figure 1 , 2 As shown, two sets of vibration mechanisms 200 are both arranged on a base 103, and the base 103 can be fixed on the ground. Each set of vibration mechanisms 200 includes an active crank 201, one end of the active crank 201 is rotatably arranged on the base 103, the other end of the active crank 201 is rotatably arranged with one end of a transmission connecting rod 202, the other end of the transmission connecting rod 202 is rotatably arranged at one end of the bottom of the drying box 101, the other end of the bottom of the drying box 101 is rotatably arranged with one end of a supporting rocker 203, and the other end of the supporting rocker 203 is rotatably arranged on the base 103.
[0034] like Figure 1 , 2 As shown, one end of an adjusting rocker 204 is rotatably provided on the top of the drying box 101, and the other end of the adjusting rocker 204 is rotatably provided on an adjusting mechanism 300. The adjusting mechanism 300 can rotate the adjusting rocker 204. The adjusting mechanism 300 is installed on a bracket 104, and the bracket 104 can be fixed on the ground.
[0035] The rotation of the active crank 201 can drive the transmission connecting rod 202 to move, thereby driving the drying box 101 to move, and then driving the pumpkin seeds in the drying box 101 to vibrate. The movement of the drying box 101 can drive the supporting rocker 203 and the adjusting rocker 204 to swing.
[0036] like Figure 1 As shown, a plurality of blowers 105 are fixed on the bracket 104, and the blowers 105 are used for drying pumpkin seeds.
[0037] Through the cooperation of the vibration mechanism 200 and the blower 105, the pumpkin seeds can be dried while vibrating, so that the pumpkin seeds are heated more evenly and the drying effect is improved. A screen 102 is arranged under the drying box 101, which can use vibration to remove impurities in the pumpkin seeds to prevent the impurities from adhering to the pumpkin seeds after drying and affecting the quality of the pumpkin seeds. The vibration law of the vibration mechanism 200 can be adjusted by rotating the adjustment rocker 204 through the adjustment mechanism 300, so that the vibration mechanism 200 can adapt to different working conditions.
[0038] like Figure 3As shown, the length of the active crank 201 is L1, the length of the transmission connecting rod 202 is L2, the distance from the rotation center of the transmission connecting rod 202 on the drying box 101 to the rotation center of the supporting rocker 203 on the drying box 101 is L3, the length of the supporting rocker 203 is L4, and the distance from the rotation center of the supporting rocker 203 on the base 103 to the rotation center of the active crank 201 on the base 103 is L5.
[0039] like Figure 3 As shown, the distance from the rotation center of the adjusting rocker arm 204 on the drying box 101 to the rotation center of the driving connecting rod 202 on the drying box 101 is L6, and the length of the adjusting rocker arm 204 is L7.
[0040] like Figure 3 , 4 As shown, the line connecting the rotation center of the supporting rocker 203 on the base 103 to the rotation center of the active crank 201 is taken as the horizontal axis, the straight line perpendicular to the horizontal axis and passing through the rotation center of the active crank 201 on the base 103 is taken as the vertical axis, the distance from the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to the horizontal axis is L8, and the distance from the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to the vertical axis is L9 or L10;
[0041] L1:L2:L3:L4:L5:L6:L7:L8:L9:L10=1:8:5:5:12:2:5:12:4:2.
[0042] When the distance from the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to the longitudinal axis is L10, the two extreme positions of the vibration mechanism 200 are as follows: Figure 7 , 8 As shown in FIG. 1 , it can be seen from the extreme positions that the vibration of the drying box 101 is mainly in the vertical direction, which can better utilize gravity to remove impurities and is suitable for removing impurities in the early stage of drying. When the distance from the rotation center of the rocker 204 to the longitudinal axis is adjusted to L9 on the adjustment mechanism 300, the two extreme positions of the vibration mechanism 200 are as shown in FIG. Figure 5 , 6 As shown, it can be seen from the extreme position that the vibration of the drying box 101 is mainly in the horizontal direction, which reduces the participation of gravity in the vibration process of the drying box 101 and reduces the damage to the pumpkin seeds. It is suitable for turning the pumpkin seeds in the middle and late stages of drying to improve the drying efficiency.
[0043] like Figure 2 As shown, the adjustment mechanism 300 includes a cylinder 301, which is mounted on a sliding seat 302. A connecting rod 303 is fixed to the output end of the cylinder 301, and adjusting rockers 204 are rotatably provided at both ends of the connecting rod 303.
[0044] like Figure 2As shown, the sliding seat 302 is slidably arranged on the adjusting seat 304 , the sliding direction of the sliding seat 302 is parallel to the telescopic direction of the cylinder 301 , and an adjusting screw 305 is rotatably arranged on the sliding seat 302 , and the adjusting screw 305 is threadedly connected to the adjusting seat 304 .
[0045] Rotating the adjusting bolt 305 can drive the sliding seat 302 to move, and then drive the cylinder 301 to move, so as to facilitate moving the position of the cylinder 301 and adjusting the position of the cylinder 301 during installation and maintenance.
[0046] The extension and retraction of the cylinder 301 can drive the connecting rod 303 to move, thereby driving the adjusting rocker 204 to rotate, and adjusting the adjusting rocker 204. When the cylinder 301 is retracted, the distance from the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to the longitudinal axis is L10 (such as Figure 4 As shown in FIG. 1 ), when the cylinder 301 is extended, the distance from the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to the longitudinal axis is L9 (as shown in FIG. Figure 3 as shown).
[0047] like Figure 2 As shown, the blower 105 is electrically connected to the controller. In this embodiment, the controller adopts a 32-bit single-chip microcomputer. The controller is electrically connected to the solenoid valve. The solenoid valve is a component used for controlling the reversal of the cylinder in the pneumatic circuit. The solenoid valve pipeline is connected to the cylinder 301.
[0048] After the blower 105 runs for a set time, the solenoid valve controls the cylinder 301 to change direction, so that the cylinder 301 extends, thereby causing the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to move to a position L9 away from the longitudinal axis.
[0049] To facilitate driving the pneumatic circuit, the air compressor pipeline is connected to the solenoid valve.
[0050] like Figure 2 As shown, in order to facilitate the rotation of the adjusting screw 305 , a hand wheel 306 is fixed on the adjusting screw 305 .
[0051] like Figure 1 As shown, in order to facilitate taking out the pumpkin seeds in the drying box 101, a discharging door 106 is rotatably provided on the side of the drying box 101.
[0052] like Figure 1 As shown, in order to facilitate driving the active crank 201 , a double-output shaft motor 107 is fixed on the base 103 , and the two output shafts of the double-output shaft motor 107 are respectively fixed with the active crank 201 .
[0053] Working process: In the initial state, the distance from the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 to the longitudinal axis is L10, and the double-output shaft motor 107 can drive the active crank 201 to rotate, thereby driving the transmission connecting rod 202 to move, and then driving the drying box 101 to move, and then driving the pumpkin seeds in the drying box 101 to vibrate. The movement of the drying box 101 can drive the supporting rocker 203 and the adjusting rocker 204 to swing, and the vibration of the drying box 101 is mainly in the vertical direction.
[0054] After the blower 105 runs for a set time, the solenoid valve controls the cylinder 301 to reverse, so that the cylinder 301 extends, and then the rotation center of the adjusting rocker 204 on the adjusting mechanism 300 moves to a position L9 away from the longitudinal axis, and the vibration of the drying box 101 is mainly in the horizontal direction.
[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
