Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fruit grading machines, and more specifically, it relates to an electronic quality-type fruit grading machine. Background Technology
[0002] An electronic weight-based fruit grading machine is a device that uses electronic weighing technology to grade fruits by weight. The fruits are placed on a conveyor belt, and their weight is precisely measured as they pass through electronic weighing sensors. Based on a preset weight range, the control system distributes the fruits to the corresponding exit channels, thus achieving the grading process.
[0003] While existing electronic weight-based fruit grading machines can accurately and quickly measure the weight of fruit and efficiently achieve fine grading, it has been found in practice that after the fruit falls from the conveyor belt into the corresponding channel, the belt conveyor inside the channel transports the fruit to the fruit basket. However, there is a height difference between the belt conveyor and the fruit basket. Due to the inertia of the belt conveyor, the fruit is prone to hitting the fruit basket as it falls from top to bottom, and there is also collision between the fruits. This makes the fruit easily damaged during the process of entering the basket, which affects subsequent storage and sales. In addition, most existing electronic weight-based fruit grading machines only discharge from one side of the channel, and the fruit basket can be filled with fruit in a short time. During the production process, a large number of personnel are required to replace the fruit basket in a timely manner.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an electronic quality-type fruit grading machine, in order to achieve a more practical value. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an electronic quality-type fruit grading machine.
[0006] The purpose and effectiveness of this electronic quality-based fruit grading machine are achieved through the following specific technical means:
[0007] An electronic quality-type fruit grading machine includes a fruit grading machine conveyor belt and fruit baskets. A belt conveyor is installed in the channel of the fruit grading machine conveyor belt, and a slide rail is installed on the bottom surface of the fruit grading machine conveyor belt. Two sets of auxiliary feeding mechanisms are symmetrically arranged on the slide rail.
[0008] Furthermore, each of the auxiliary feeding mechanisms includes a tilting component and a basket placement component, and a linkage component is installed between the tilting component and the basket placement component, with a reset mechanism installed on the linkage component.
[0009] Furthermore, the tilting assembly includes a guide plate rotatably mounted on the outer wall of the discharge end of the belt conveyor, and an installation groove is provided in the middle of the guide plate, in which an electronic weighing platform is installed.
[0010] Furthermore, the basket placement assembly includes a fruit basket base, the top surface of which has a slot for matching the fruit basket, and the bottom surface of which is evenly equipped with first pulleys, which are slidably disposed within a slide rail.
[0011] Furthermore, the linkage assembly includes a first traction rod and a second traction rod. One end of the first traction rod is fixedly connected to the outer wall of the fruit basket base. One end of the second traction rod is hinged to a hinge joint, which is fixedly installed on the bottom surface of the guide plate. The other end of the second traction rod is fixedly installed with a shaft. The other end of the first traction rod is rotatably disposed in the middle of the shaft. The two ends of the shaft are rotatably mounted with second pulleys, which are slidably disposed within a slide rail.
[0012] Furthermore, the reset mechanism includes a traction block and an electric telescopic rod. The traction block is fixedly installed on the bottom surface of one end of the first traction rod near the fruit basket base. The electric telescopic rod is fixedly installed in the middle of the slide rail, and the telescopic end of the electric telescopic rod is fixedly installed on the side wall of the traction block.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This utility model uses a reset mechanism to pull the linkage component to move. Under the action of the linkage component, the guide plate in the tilting component gradually rotates and tilts. At the same time, the fruit basket base in the basket placement component carries the fruit basket on it closer to the front end of the guide plate. The front end of the guide plate approaches the inner wall of the fruit basket, which shortens the contact distance between the fruit and the inner wall of the fruit basket during the falling process. It also changes the falling height of the fruit, reduces the impact force of the fruit hitting the inner wall of the fruit basket, and thus reduces the probability of the fruit being injured by impact.
[0015] 2. This utility model uses an electric telescopic rod to slide the fruit basket base to a preset position. The electric telescopic rod quickly extends and resets, thereby driving the guide plate and the fruit basket base to reset. The fruit inside the fruit basket rolls within the basket due to the inertia of the basket's reset, thus being evenly piled up inside the basket, eliminating the need for manual sorting.
[0016] 3. When the fruit in the fruit basket reaches a certain weight, that is, when the fruit basket is close to full, the belt conveyor rotates in the opposite direction to send the fruit to the guide plate on the other side, and then put it into the fruit basket on the other side. This provides workers with enough time to change the fruit basket, reducing the intensity of work and the input of personnel. Attached Figure Description

[0032] Example:
[0033] As attached Figure 1 To be continued Figure 4 As shown: an electronic quality-type fruit grading machine, including a fruit grading machine conveyor belt 1 and a fruit basket 4, characterized in that: a belt conveyor 2 is installed in the channel of the fruit grading machine conveyor belt 1, a slide rail 3 is installed on the bottom surface of the fruit grading machine conveyor belt 1 at the belt conveyor 2, and two sets of auxiliary feeding mechanisms 5 are symmetrically arranged on the slide rail 3.
[0034] Each of the auxiliary feeding mechanisms 5 includes a tilting component and a basket placement component. A linkage component is installed between the tilting component and the basket placement component, and a reset mechanism is installed on the linkage component.
[0035] The tilting assembly includes a guide plate 501 that is rotatably mounted on the outer wall of the discharge end of the belt conveyor 2. The guide plate 501 has an installation groove 5011 in the middle, and an electronic weighing platform 5012 is installed in the installation groove 5011.
[0036] The basket placement assembly includes a fruit basket base 503. The top surface of the fruit basket base 503 is provided with a slot for matching the fruit basket 4. The bottom surface of the fruit basket base 503 is evenly equipped with first pulleys 504, which are slidably disposed in the slide rail 3.
[0037] Above, the fruit is conveyed to the tilting component by the belt conveyor 2. After the tilting component reaches the preset weight, the reset mechanism pulls the linkage component to move. Under the action of the linkage component, the guide plate 501 in the tilting component gradually rotates and tilts. At the same time, the fruit basket base 503 in the basket placement component carries the fruit basket 4 on it to the front end of the guide plate 501.
[0038] The front end of the guide plate 501 is close to the inner wall of the fruit basket 4, which shortens the contact distance between the fruit and the inner wall of the fruit basket 4 during the fall. At the same time, it changes the height of the fall of the fruit, reduces the impact force of the fruit hitting the inner wall of the fruit basket 4, and thus reduces the probability of the fruit being injured by impact.
[0039] As attached Figure 1 To be continued Figure 4As shown, in some embodiments, the linkage component includes a first traction rod 505 and a second traction rod 506. One end of the first traction rod 505 is fixedly connected to the outer wall of the fruit basket base 503. One end of the second traction rod 506 is hinged to a hinge joint 502, which is fixedly installed on the bottom surface of the guide plate 501. The other end of the second traction rod 506 is fixedly installed with a shaft 507. The other end of the first traction rod 505 is rotatably disposed in the middle of the shaft 507. The two ends of the shaft 507 are rotatably mounted with second pulleys 508, which are slidably disposed in the slide rail 3.
[0040] The reset mechanism includes a traction block 510 and an electric telescopic rod 509. The traction block 510 is fixedly installed on the bottom surface of one end of the first traction rod 505 near the fruit basket base 503. The electric telescopic rod 509 is fixedly installed in the middle of the slide rail 3. The telescopic end of the electric telescopic rod 509 is fixedly installed on the side wall of the traction block 510.
[0041] On top of it, the electric telescopic rod 509 slowly retracts, pulling the first traction rod 505 to slide towards the middle of the slide rail 3. Then, under the interaction of the hinge joint 502, the first traction rod 505, the second traction rod 506, and the shaft 507, the fruit basket base 503 drives the fruit basket 4 on it to slide towards the middle of the slide rail 3. At the same time, the guide plate 501 gradually rotates and tilts, and the front end of the guide plate 501 approaches the inner wall of the fruit basket 4, so that the fruit falls into the fruit basket 4.
[0042] The specific usage and function of this embodiment are as follows: When fruit falls onto the belt conveyor 2, the belt conveyor 2 transports the fruit to the electronic weighing platform 5012 of the guide plate 501. When the electronic weighing platform 5012 on the guide plate 501 shows that the weight of the fruit accumulation has reached the maximum preset weight, the electric telescopic rod 509 slowly retracts and pulls the first traction rod 505 to slide towards the middle of the slide rail 3. Then, under the interaction of the hinge joint 502, the first traction rod 505, the second traction rod 506, and the shaft 507, the fruit basket base 503 drives the fruit basket 4 on it to slide towards the middle of the slide rail 3. At the same time, the guide plate 501 gradually rotates and tilts, and the front end of the guide plate 501 approaches the inner wall of the fruit basket 4, so that the contact distance between the fruit and the inner wall of the fruit basket 4 during the falling process is shortened. At the same time, the falling height of the fruit is changed, reducing the impact force of the fruit hitting the inner wall of the fruit basket 4, thereby reducing the probability of the fruit being injured by impact.
[0043] Once the electric telescopic rod 509 drives the fruit basket base 503 to slide to the preset position, the electric telescopic rod 509 quickly extends and resets, thereby driving the guide plate 501 and the fruit basket base 503 to reset. The fruit inside the fruit basket 4 is affected by the inertia of the fruit basket 4 resetting, and thus rolls inside the fruit basket 4, and is evenly piled inside the fruit basket 4, without the need for manual sorting;
[0044] When the fruit in the fruit basket 4 reaches a certain weight, the inner cavity of the fruit basket 4 will also be close to full. At this time, the belt conveyor 2 will rotate in the opposite direction and send the fruit to the guide plate 501 on the other side. Then, in the same way as above, the fruit will be put into the fruit basket 4 on the other side, thus providing the staff with enough time to replace the fruit basket 4, reducing the intensity of the work and the input of personnel.
[0045] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
