[0002] Lychees are popular among the public for their rich nutritional value and unique flavor. In order to ensure that lychees maintain the best quality during transportation and sales, packaging is particularly critical. When packing lychees, they need to be classified and packaged according to their different sizes. On the one hand, classifying lychees by size helps ensure that the lychees in the package are arranged neatly and reduce collisions and damage during transportation; on the other hand, classified packaging also helps improve the sales effect of lychees.

[0003] Traditionally, litchi packaging usually relies on manual grading equipment to grade the litchi by size, and then the graded litchi are packed into boxes. However, this processing method separates grading and boxing, resulting in low efficiency in litchi packaging. In view of this, we propose a mobile litchi grading and packaging workbench.

DETAILED DESCRIPTION

[0027] 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.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 5The mobile litchi grading and packaging workbench comprises a base 1, and a grading conveying part 2 is arranged above the base 1; a plurality of positioning frames 10 are fixed at the front side of the top of the base 1, and a packaging box 11 for collecting litchi is arranged in the opening of the positioning frame 10; a side plate 12 is fixed at both ends of the top of the base 1; the grading conveying part 2 is used for grading litchi; it comprises a horizontally movable movable seat 23, and guide rods 233 are fixed at the four corners of the top of the movable seat 23, and two springs 234 are sleeved on the guide rods 233; two symmetrical support plates 24 are arranged above the movable seat 23, and a plurality of connecting grooves 241 are opened on the front support plate 24, and connecting blocks 242 are fixed at the bottom ends of the left and right side walls of the support plate 24, and the guide rods 233 passes through the connecting block 242, and the two opposite ends of the two adjacent connecting blocks 242 are pressed against the connecting block 242; a vibration motor 25 is also installed on the rear end face of the support plate 24 located on the rear side; a plurality of strip plates 26 distributed in the vertical direction are fixed on the left and right sides between the two support plates 24, and a sieve plate 261 is fixed between two adjacent strip plates 26; a connecting bin 27 is fixed on the front side of the connecting groove 241, and a shell 28 with a bottom opening is fixed between the front ends of the connecting bins 27, and a plurality of electric cylinders 29 are installed on the front end face of the shell 28, and a baffle 291 is fixed between the ends of the piston rods of two adjacent electric cylinders 29, and the baffle 291 is pressed against the connection between the shell 28 and the connecting bin 27.

[0030] Furthermore, a screw rod 20 is rotatably mounted between the two side plates 12, and a motor 22 for driving the screw rod 20 to rotate is mounted on one side of the screw rod 20; a fixing block 232 threadedly connected to the screw rod 20 is fixed at the bottom center of the movable seat 23. The rotation of the screw rod 20 can drive the grading conveying part 2 to move horizontally, thereby facilitating the movement of the housing 28 to the top of different packaging boxes 11, so as to facilitate the packaging of lychees of different sizes.

[0031] In this embodiment, two connecting rods 21 are fixedly connected between the two side plates 12 by bolts, and two guide blocks 231 are fixed to the bottom of the movable seat 23. The connecting rod 21 passes through the guide blocks 231 and is slidably connected to the guide blocks 231. The setting of the connecting rod 21 guides the horizontal movement of the movable seat 23, ensuring the stability and smoothness of the movable seat 23.

[0032] In this embodiment, the sieve plate 261 is inclined, and the sieve plate 261 is fixedly connected to the strip plate 26 by bolts. The inclined design is conducive to the lychees on the sieve plate 261 rolling toward the connecting groove 241, which is conducive to subsequent unloading.

[0033] In this embodiment, the inner bottom of the connecting bin 27 is inclined, and the end of the connecting bin 27 is fixedly connected to the support plate 24 and the housing 28 by bolts. This design facilitates the movement of the lychees in the connecting bin 27 into the housing 28, which is convenient for subsequent unloading.

[0034] In this embodiment, the overall shape of the positioning frame 10 is U-shaped, and the positioning frame 10 is fixedly connected to the base 1 by bolts. The setting of the positioning frame 10 limits the position of the packaging box 11, which is conducive to the lychees falling into the housing 28 being collected by the packaging box 11.

[0035] In this embodiment, the top of the guide rod 233 is coaxially fixed with a limit block 235, and the diameter of the guide rod 233 is smaller than the diameter of the limit block 235. The setting of the limit block 235 plays a limiting role, which can prevent the connecting block 242 from separating from the connecting rod 21, and ensure the stability of the support plate 24.

[0036] In this embodiment, the bottom of the connecting groove 241 and the sieve plate 261 are located on the same horizontal plane, and the height of the connecting groove 241 is 9-11 cm. The preferred height of the connecting groove 241 is 10 cm. This design facilitates the movement of the lychees on the sieve plate 261 into the connecting groove 241, making it convenient to collect the lychees.

[0037] It can be understood that a plurality of sieve holes are provided on the sieve plate 261 in this embodiment, and the apertures of the sieve holes on the sieve plates 261 distributed from top to bottom decrease successively. Therefore, after the litchis are screened through the sieve plate 261, the sizes of the litchis retained on the sieve plates 261 distributed from top to bottom decrease successively. This design facilitates the grading of litchis of different sizes.

[0038] It is worth noting that the motor 22 and the vibration motor 25 involved in this embodiment are conventional technologies and will not be described in detail here.

[0039] Before specific use, the user first turns on the power of the vibration motor 25, and the vibration motor 25 starts to work. The vibration motor 25 drives the support plate 24 to vibrate, and the vibration of the support plate 24 drives the strip plate 26 to vibrate, and the sieve plate 261 vibrates synchronously. Then the user pours the lychees on the top sieve plate 261. As the sieve plate 261 vibrates, small particles of lychees fall downward, while large particles of lychees are trapped on the sieve plate 261, and the lychees trapped on the sieve plate 261 enter the connection slot 241 into the connection bin 27. When the screening is completed, the user stops the power of the vibration motor 25.

[0040] During specific use, the user first turns on the power of the motor 22, and the motor 22 starts to work. The output shaft of the motor 22 rotates to drive the screw rod 20 to rotate. As the screw rod 20 rotates, the movable seat 23 moves horizontally, and the movable seat 23 drives the shell 28 to move horizontally at the same time. When the shell 28 moves to the top of the corresponding packaging box 11, the user stops the power of the motor 22, and then the user turns on the power of the corresponding electric cylinder 29. The piston rod of the electric cylinder 29 contracts and drives the baffle 291 to move. At this time, the lychees in the connecting bin 27 enter the shell 28 and fall into the packaging box 11 through the shell 28; repeat the above steps, as the shell 28 moves to the top of different packaging boxes 11, lychees of different sizes can be arranged in different packaging boxes 11.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
