The central shaft and the hollow shaft are driven by two V-belts with different transmission ratios, so that the same-direction and different rotating speeds of the shafts are realized. The rotation centers are positioned on the same straight line, so that the same-direction different rotation speeds, namely the same-direction rotation speeds and different rotation speeds of the two devices are different from the same-direction rotation speed of the limiting feeding rod. The potatoes are conveyed intermittently by a limit feeding rod.
And (3) carrying in an equal interval mode: the hollow shaft I-05 has a certain rotating speed and moves at a uniform speed, the distance between the two feed rods can only accommodate one potato, and the feed rods move a certain distance to enable the potato to reach the leak hole, so that the uniform interval is realized. The speed of the limiting feeding rod is controlled so as to adjust the falling time of the potatoes.
Because the speed of the rotary evacuation cone is higher than that of the limiting feeding rods, the potatoes have sufficient time to reach an ideal position, and the potatoes which reach an ideal state are ensured to be arranged between the two feeding rods.
The bearing pot is provided with a hollow circle at the center, a U-shaped slideway I-11 is formed between the inner circle of the excircle, and the height of the bearing pot is approximately three times of the short axis of the potatoes.
The working principle of the device is as follows: the rotating evacuation cone provides friction force for the potatoes, and the force of the potatoes is applied to any one of two ends of the potatoes in the long axis direction.
According to the force translation theorem: the force acting on the rigid body can be equivalently moved to any point in the rigid body from the original acting point in parallel, and a couple is added at the same time, and the couple is the moment of the original force to the new acting point. The friction force f1 can be translated to the center of gravity of the potato to obtain a force with the same magnitude as f1 and a force couple M ═ l × f1, so that the potato is driven to rotate. I is the distance from the point of action of the frictional force to the center of gravity of the potato.
When the long axes of the potatoes are arranged into regular circular arcs on the u-shaped slide way, the state is an ideal state, the limiting feeding rod moves at a uniform speed, and the potatoes are fed to the leakage holes at equal intervals.
In a specific application, the potatoes are initially randomly distributed in the apparatus, in the following three cases.
1. The potatoes are already in an ideal position in the U-shaped slide way I-11 of the bearing pot, and the long shaft of the potatoes corresponds to the U-shaped slide way I-11 and is vertical to the rotary evacuation cone.
2. A part of potatoes are arranged in a U-shaped slideway I-11 of the bearing pot, and a part of potatoes are contacted with the rotary evacuation cone.
3. The whole potato is arranged on the rotary evacuating cone.
The motor operation drives the rotation of the rotary evacuation cone through the central shaft, the limiting feeding rod slowly rotates, the speed is smaller than that of the rotary evacuation cone, the pot and the evacuation blades are borne, and the shade and the leak holes are fixed.
Sports example 1 (corresponding to the first case)
The rotating evacuation cone generates a thrust force F and a friction force F due to the contact with the potatoes1. In the vertical direction, G ═ Fn(ii) a In the horizontal direction, the direction of the horizontal direction,
1. if thrust force F>Frictional force f1Then frictional force f1The potatoes move forwards under the action of a thrust F due to static friction; if F<F1, F is not enough to push the potatoes. The potatoes are in an ideal state in the U-shaped slide way I-11, and if the potatoes cannot move forwards, the potatoes will finally act on the acting force F of the limiting feeding rod1The medium potatoes are pushed to the weep holes;
2. if the potato advances under thrust F effect, if advance to the position of next spacing pay-off pole, still can be blockked by spacing pay-off pole, along with the motion arrival export of spacing pay-off pole.
Therefore, no matter F or F1The potatoes reach the outlet at a specified time.
Where F is T/L, T is the turntable torque, L is the turntable radius R
Wherein the friction force f between the potatoes and the U-shaped slideway I-111＝u1mg
Sports example 2 (corresponding to the second case)
On the rotating evacuation cone, a force F is provided in the direction perpendicular to the generatrix of the rotating evacuation cone, and the force F is decomposed into a force F ' perpendicular to the long axis and a force F ' parallel to the long axis, and the state of the potatoes in the direction of the long axis can be ignored due to insufficient F '.
1. If the long axis direction of the potatoes is not in the same direction with the generatrix, when the front potatoes move forwards, a certain space is reserved between the potatoes and the front potatoes, because the inclination angle between the potatoes and the horizontal plane is not 90 degrees, the potatoes fall to the U-shaped slide way I-11 from one end under the action of the self gravity component and the F' to reach an ideal state, and therefore the situation needs F>f1For giving the potatoes a reoriented space.
2. If the potatoes are close to each other or the long axis of the potatoes and the generatrix of the rotary evacuation cone are on the same straight line, f2A moment is generated on the center of gravity of the potato, so that the potato rotates around the center until the long axis is vertical to the radius of the rotary evacuation cone, and an ideal state is achieved. Under two kinds of circumstances, the potato is finally carried to the small opening slowly under the effect of spacing feed bar, because carry slowly, the potato removes certain distance, falls under the effect of gravity G, and its whereabouts state is that potato major axis and gravity are on same line.
Because the potato is turned, static friction force cannot be generated between the potato and the rotating evacuation cone, if the static friction force is generated, no force is generated on the rotating evacuation cone in the direction vertical to the long axis of the potato, the static friction force is balanced with F', and F is equal to F2The rotation of the rotary evacuation cone is blocked, and the direction of the potatoes cannot be adjusted. Thus F > F2Wherein the friction force f between the potatoes and the rotating evacuation cone2＝μ2FN2。
G＝FN1+FN2sinθ
G is the weight of the potato, and G is mg.
FN2The supporting force of the potatoes on the rotating evacuation cone is in the unit of N.
Theta is an included angle between the turntable bus and the central shaft.
FN1The supporting force of the potatoes on the U-shaped slideway I-11 is shown.
FN2cosθ＝FN3
FN3To bear the supporting force of the inner wall of the pot to the potatoes.
The moment M of the rotating evacuation cone to the potato is L1×f2cos α, unit N · m.
α is the included angle between the long axis of the potato and the generatrix of the rotary evacuating cone.
L1The distance from the point of friction to the center of the potato, here, half the long axis of the potato.
Sports example 3 (corresponding to the third case)
The whole potato is arranged on the rotary evacuating cone, and the potatoes under the former two conditions are blocked from falling into the U-shaped slideway I-11 of the bearing pot under the rotary evacuating cone. In this case, the circular motion of the potatoes on the rotating evacuation cone is equivalent to that of the potatoes in the former two kinds. As the potatoes in the U-shaped slide way I-11 have an upward force along the direction of the rotating evacuation cone generatrix and a downward force component of the potatoes per se along the direction of the rotating evacuation cone generatrix, the potatoes are not moved along the direction of the rotating evacuation cone generatrix.
If the force F provided by the rotating evacuation cone is larger than the friction force F3 of the potatoes on the turntable, the potatoes and the rotating evacuation cone slide relatively, and the potatoes are hardly moved; if F is less than F, the potatoes move along with the rotating dispersing cone due to static friction force, the potatoes are rotated to touch the dispersing leaves, and the potatoes stop moving forwards due to the blocking of the dispersing leaves at the moment because the dispersing leaves are fixed. The potatoes in the lower part reach the ideal position under the two conditions, after being pushed to the leaking hole by the limiting feeding rod to reach the next device, the potatoes on the rotating evacuation cone fall into the bearing pot, and the potato bearing pot is changed into one of the motion examples 1 and 2, and finally reaches the leaking hole position at the outlet under the action of the limiting feeding rod.
Dynamic friction factor mu2Measurement of
Measuring dynamic friction factor by Newton's theorem, sliding the potato down along the same slope with the rotating evacuation cone material at acceleration a, the slope being α2The potato is subjected to stress analysis to obtain
Measuring acceleration by using photoelectric gate, installing two photoelectric gates on the inclined plane, and setting the time for passing through the first photoelectric gate as t1The speed of the slide block is v1The time for passing through the second photogate is t2Velocity v2The time interval of the left light barrier of the slide block passing through the two photoelectric doors is t3Correcting t by adopting the center speed of the light barrier as the speed of the potato3Is t4Then, then
Automatic acquisition of time t by means of a photogate1、t2、t3The dynamic friction factor mu can be calculated by reading the angle in m/s2。
The dynamic friction factor mu between the potato and the U-shaped slideway I-11 can be obtained by the same method1。
