Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of fruit sorting, and in particular to a fruit sorting vehicle. Background Art

[0002] After the fruits are picked, they need to be sorted for quality to increase their economic value. For a long time, my country's fruit production has had the concept of "focusing on pre-harvest production and neglecting post-harvest processing". The post-harvest processing rate is about 30%, which is far lower than the 50% level in developed countries. This causes the loss of fruits due to post-harvest rot to be as high as more than 30%, and the direct economic losses exceed 1 billion yuan. The market urgently needs to improve the fruit sorting rate and added value of fruits. At present, fruit sorting mainly relies on floor-standing fruit sorting machines and manual sorting to achieve the sorting purpose, and it is impossible to achieve on-site sorting at the place of fruit production. Moreover, traditional fruit sorting machines can generally only achieve external quality sorting, and cannot achieve simultaneous sorting of the internal and external quality of fruits, and cannot achieve accurate sorting of fruits. In addition, most of the domestic sorting is still mostly manual sorting, and this sorting method will definitely have some human errors. Therefore, the above traditional sorting method still has some shortcomings in efficiency; For example, the inability to sort fruits at the place of production requires an increase in the transportation cost of the fruits, and the fruits will also be damaged and wasted to a certain extent during transportation, which greatly increases the waste of resources.

[0024] In order to facilitate the understanding of the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-6 As shown, this embodiment provides a fruit sorting vehicle, including a feeding mechanism, a transmission mechanism, a fruit quality detection mechanism, an automatic sorting mechanism and a control system. It is mainly used for sorting some small round fruits, such as apples, peaches, pears and other fruits. The utility model combines a fruit sorting machine and a car into one, which can not only meet the requirements of automatic fruit sorting, but also meet the requirements of vehicle-mounted sorting, and can realize on-site sorting, making the sorting location more flexible, overcoming the traditional workshop-type centralized sorting method, which greatly increases the sorting efficiency of fruits and reduces the transportation cost of fruits and the loss and waste of fruits.

[0026] First, the feeding mechanism is spliced ​​onto the vehicle-mounted sorting machine. The feeding mechanism is divided into two parts: a roller conveyor belt 4 and a fruit delivery machine 3.

[0027] The feeding mechanism of the present invention adopts a high-throughput feeding mechanism, which is suitable for the practical vehicle-mounted fruit sorting. First, the feeding mechanism is spliced ​​on the vehicle-mounted sorting machine, and fixedly installed by a triangular frame and a double-legged bracket. The roller conveyor belt 4 support adopts a triangular bracket that is easy to disassemble and assemble. The bottom of the triangular bracket is equipped with a motor mounting plate. The transmission shaft is driven by the motor to further drive the transmission roller. The spacing between the transmission rollers is smaller than the fruit diameter. The transmission roller drives the fruit to be transmitted upward. The fruit delivery machine 3 support adopts a foldable support frame, which can rotate around it. The fruit delivery machine 3 is installed on the upper end of the roller conveyor belt 4. The fruit delivery machine 3 is provided with a synchronous belt 32 wheel and a synchronous belt 32. The synchronous belt 32 is equipped with a soft plastic operating slot 2. The synchronous belt 32 is driven by the motor. The slot 2 on the synchronous belt 32 can move the fruit on the discharge hopper, bring the fruit to the slot 2, and transmit the fruit on the discharge hopper one by one.

[0028] Further, the fruits on the synchronous belt 32 will fall into the fruit sliding groove 12, the fruits on the fruit sliding groove 12 will fall into the chute of the sorting machine, the fruits on the chute will fall into the fruit cup 25, the internal motor of the vehicle-mounted fruit sorting machine will drive the transmission chain 27, and further, the fruit cup 25 on the vehicle-mounted fruit sorting machine will transfer the fruits to the dark box 5 one by one.

[0029] Furthermore, when the fruit on the fruit cup 25 passes through the dark box 5, the halogen lamp and the fill light 19 inside the dark box 5 will illuminate, and the high-speed camera inside the dark box 5 will collect photos of the fruit. The high-speed camera can capture the external features of the fruit, and further extract the quality data features based on deep learning. Through computer image processing, the quality features of different fruits can be compared, and the external quality judgment of the fruit can be made through computer deep learning. Furthermore, after the fruit has passed the external quality inspection, it must also pass the internal quality inspection. The spectrometer 21 at the bottom of the fruit cup 25 will collect the spectral images of the path fruits one by one, and through the annular diffuse transmission detection method, more effective internal quality information of the fruit can be obtained. The fruit information is processed by a computer. If the fruit has defects, the bad fruit will be screened out through a sorting mechanism. If there are no defects, it will be further sorted by size.

[0030] Furthermore, when the fruits on the fruit cup 25 pass through the automatic fruit labeling machine 14, the labeling machine can label the fruits with QR codes in turn to authenticate the origin and quality information.

[0031] Furthermore, the computer controls the sensor 23, and the rotating lever on the sensor 23 rotates upon receiving the computer command. Furthermore, the rotating lever on the sensor 23 moves the lever at the bottom of the fruit cup 25, and the lever at the bottom of the fruit cup 25 contracts inward. When the lever at the bottom of the fruit cup 25 passes through the chute, it tilts, and eventually the fruit falls off, and further, falls from different sorting holes on both sides of the sorting machine, thereby completing the sorting.

[0032] The vehicle-mounted fruit sorting machine is provided with a shock-absorbing base and a connecting frame 10, which reduces the damage to the machine caused by the vibration of the vehicle during driving.

[0033] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims, any one of the embodiments claimed for protection may be used in any combination. As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the aforementioned embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application.
