Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings.
As shown in fig. 1-6, a tray turning device of a watermelon sorting system mainly comprises a base 1, a side plate 2, a moving cam 3, a lower roller 41, a push rod 4, an upper roller 42, a bracket 5, a top cover 6, a top cover shaft 7 and a sucker type electromagnet 8; the sucker type electromagnet 8 is fixed on the base 1 in a threaded connection mode, the movable cam 3 is arranged in a sliding groove of the base 1 and is in high-pair connection with the push rod 4 above through the lower roller 41, the lower roller 41 is installed at the lower end of the push rod 4, the bracket 5 is fixed on the side plate 2 and is provided with a rectangular hole, so that the push rod 4 linearly reciprocates through the rectangular hole, the push rod 4 forms high-pair contact with the top cover 6 through the upper roller 42 above, the top cover 6 is fixedly connected with the top cover shaft 7, and the top cover shaft 7 is installed on the side plate 2; during operation, sucking disc formula electro-magnet 8 circular telegram adsorbs removal cam 3 to promote push rod 4 rebound, make top cap 6 rotate certain angle clockwise, overturn the tray top of watermelon sorting system, make the collection area of corresponding grade of watermelon on the tray fall, then, sucking disc formula electro-magnet 8 outage, the removal cam 3 in the spout keeps away from sucking disc formula electro-magnet 8 under the action of gravity of top cap 6 and push rod 4, push rod 4 falls downwards, top cap 6 falls.
As shown in figures 1-3, in order to better realize the tray turning function of the watermelon sorting system, the upward swing of the top cover 6 is realized by the transmission mode of a cam mechanism consisting of the moving cam 3 and the push rod 4.
As shown in figures 1-3, in order to better realize the tray turning function of the watermelon sorting system, the push rod 4 forms a high pair connection with the lower moving cam 3 through the lower roller 41, and the push rod 4 forms a high pair contact with the top cover 6 through the upper roller 42. And, the upper surface that the moving cam 3 contacts with the lower roller 41 is divided into three parts according to the degree of inclination, which are the gentle section located at the top of the moving cam 3, the gentle section located at the bottom of the moving cam, and the inclined section located between the two gentle sections with a larger degree of inclination, and the areas where the three parts join are in smooth transition. The inclined section consists of two smoothly-transited curves, the curve connected with the gentle section at the top of the moving cam is a convex curve, and the curve connected with the bottom of the moving cam is a concave curve. The movable cam 3 adopts the upper surface structure, so that the push rod 4 can realize stable starting and stopping actions on the movable cam 3, and quick lifting work can be realized by virtue of the inclined section.
As shown in fig. 1-3, in order to better realize the tray turning function of the watermelon sorting system, the side plate 2 is disposed on one side of the base 1, the side plate 2 can be integrally formed with the base 1 and vertically extended upwards from the base 1, and the side plate 2 can also be made of a separate plate material and fixedly connected to the base 1 by riveting, screwing and the like.
As shown in FIG. 4, in order to better realize the tray flipping function of the watermelon sorting system, the push rod 4 is composed of two clamping plates which are assembled together by an upper roller 42 and a lower roller 41.
As shown in fig. 5, in order to better realize the tray turning function of the watermelon sorting system, the bracket 5 is L-shaped, two through holes are arranged on the vertical section of the L-shape of the bracket 5, the fixing piece passes through the through holes to fix the bracket 5 on the side plate 2, a rectangular hole is arranged on the horizontal section of the L-shape of the bracket 5, the push rod 4 passes through the rectangular hole, and the push rod 4 is driven by the moving cam 3 to linearly reciprocate through the rectangular hole.
According to the tray turning device of the watermelon sorting system, the push rod 4 is driven to move upwards through the transmission mode of the cam mechanism, the top cover 6 rotates clockwise for a certain angle, the watermelon tray of the watermelon sorting system is turned over, and the watermelon falls into the collecting area of the corresponding grade, so that the purpose of sorting the watermelon grade is achieved.
The invention has simple structure and reliable work, the rectangular hole on the bracket is used for restricting the displacement of the push rod 4 in the horizontal direction in the reciprocating motion process, and the horizontal displacement of the push rod 4 in the horizontal direction in the reciprocating motion process is basically avoided due to the restriction action of the rectangular hole, namely, the push rod 4 can not generate unexpected left-right or front-back swing in the horizontal direction in the reciprocating motion process, thereby reliably ensuring the correct position matching relationship between the push rod 4 and the moving cam 3 and avoiding the situations of jamming and even abnormal watermelon jacking caused by the dislocation of the contact surface of the lower roller 41 on the push rod 4 and the moving cam 3. Therefore, the tray overturning device of the watermelon sorting system can reliably drive the push rod 4 to reciprocate on the moving cam 3, and can smoothly and reliably overturn the watermelon tray.
Further, in order to ensure that the watermelon tray is reliably turned over, the moving cam 3 is provided with a groove matched with the lower roller 41, the lower roller 41 is accommodated in the groove, and the groove can further ensure the stable contact and matching of the lower roller 41 and the moving cam 3, so that the lower roller 41 is prevented from falling out of the moving cam 3 in the reciprocating motion process of the push rod 4.
Further, in order to ensure reliable knock-over of the watermelon tray, both ends of the upper surface of the moving cam 3 in contact with the lower rollers 41, i.e., at the edges of the top upper surface and the bottom upper surface of the moving cam 3, are provided with stoppers protruding from the upper surface, respectively, for blocking the lower rollers 41 at the top and bottom of the moving cam 3, preventing the lower rollers 41 from coming out of the moving cam 3 in the direction of movement of the moving cam 3.
Further, in order to ensure that the watermelon tray is reliably turned over, the length of the chute on the base 1 for accommodating the moving cam 3 needs to be set according to the position relationship between the push rod 4 and the moving cam 3. When the moving cam 3 moves to be closest to the sucker electromagnet 8 (i.e., the position shown in fig. 2) under the suction action of the sucker electromagnet 8, the push rod 4 is located at the top of the moving cam 3, and the push rod 4 is in contact with the upper surface of the top of the moving cam 3 and does not exceed the top of the moving cam 3. The sucker type electromagnet 8 is powered off, the push rod 4 falls back downwards, the moving cam 3 is far away from the sucker type electromagnet 8, when the moving cam 3 is farthest away from the sucker type electromagnet 8 (namely, the position shown in figure 3), the push rod 4 is positioned at the bottom of the moving cam 3, and the push rod 4 is in contact with the upper surface of the bottom of the moving cam 3 and does not exceed the bottom of the moving cam 3. The two positions shown in figures 2 and 3 are now positions that ensure the proper operation of the device. The length of the chute needs to ensure that the movement of the movable cam 3 does not exceed the normal working position, the problem that the push rod 4 is separated from the movable cam 3 due to the further movement of the movable cam 3 in the chute caused by the overlong length of the chute can be solved, and the problem that the push rod 4 cannot enter the top or bottom area of the movable cam 3 due to the fact that the movable cam 3 cannot enter the top or bottom area of the movable cam 3 caused by the overlong length of the chute, and then the watermelon tray cannot be reliably jacked and turned over can be solved.
While the preferred embodiments of the present invention have been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
