Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of receiving hoppers, and particularly relates to a fruit and vegetable anti-breaking receiving hopper. BACKGROUND

[0002] A color sorter is a high-precision device for sorting granular materials (such as rice, tea, nuts, minerals, plastics, fruits and vegetables, etc.) according to color, volume and other differences by using optical principles. When the color sorter is working, the materials fall from the vibrating feeder, forming a uniform material flow. The high-speed camera scans and collects images of the falling materials. After the image processing system identifies the defective particles of different colors, it sends a command to drive the spray valve to blow the defective particles away from the original track. Finally, the good and defective products fall into the corresponding receiving hoppers to achieve sorting.

[0003] Traditional receiving hoppers are mostly made of stainless steel and welded together. The internal structure is usually protected by adding a series of silica gel skins to prevent the materials from directly contacting the stainless steel hopper body during the falling process, thereby providing a buffering effect and reducing the material breakage rate. However, for fruits and vegetables with a damaged skin, this buffering method cannot provide sufficient protection and may increase the risk of secondary damage. If the secondarily damaged fruits and vegetables are not picked out in time, they will not only rot and deteriorate, but also cause cross-contamination, thereby posing a significant risk to product hygiene and safety.

[0004] To solve the above problems, the present application provides a fruit and vegetable anti-breaking receiving hopper. SUMMARY

[0013] As a further optimization of the present application, the outer periphery of each of the first guide roller and the second guide roller is covered with soft glue, and the inner side of the buffer belt is tightly matched with the soft glue.

[0014] As a further optimization of the present application, a plurality of arc-shaped openings are formed in the two sides of the material receiving hopper body, the plurality of arc-shaped openings are respectively corresponding to the first buffer member, the second buffer member, the third buffer member and the fourth buffer member, and are used for fixing the installation angle of the first buffer member, the second buffer member, the third buffer member and the fourth buffer member by the screw, and screw holes are formed in the sides of the two loading square tubes away from each other for cooperation with the screw.

[0015] As a further optimization of the present application, the blocking curtain comprises a first blocking curtain body, a second blocking curtain body and a loading part, the loading part is installed on the top wall in the material receiving hopper body and located in the upper area of the substandard product discharging channel, and the first blocking curtain body and the second blocking curtain body are respectively installed on the two sides of the loading part.

[0016] As a further optimization of the present application, the loading part comprises a loading frame, the loading frame is installed on the top wall in the material receiving hopper body, and the two sides of the loading frame are respectively provided with a fixing plate, and the first blocking curtain body and the second blocking curtain body are respectively fixed on the two fixing plates.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application is further described in detail below in combination with specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0033] As Figures 1-10 shown, the present application proposes a fruit and vegetable anti-breaking material receiving hopper, which comprises a material receiving hopper body 1;

[0034] The side of the material receiving hopper body 1 is formed with a feeding opening, and the material receiving hopper body 1 is installed with an obliquely arranged first buffer piece 2, and the first buffer piece 2 divides the material receiving hopper body 1 into a finished product chamber and a substandard product chamber;

[0035] The finished product chamber is installed with a second buffer piece 3 and a third buffer piece 4 arranged in an inverted eight structure, and a finished product falling channel is formed between the second buffer piece 3 and the third buffer piece 4, and the substandard product chamber is installed with two fourth buffer pieces 5 arranged in sequence and obliquely, and a substandard product falling channel is formed between the first buffer piece 2 and the two fourth buffer pieces 5;

[0036] The first buffer piece 2, the second buffer piece 3, the third buffer piece 4 and the fourth buffer piece 5 have the same overall structure but different sizes;

[0037] A baffle 6 is installed in the substandard product chamber at the upper region of the substandard product falling channel to pre-buffer the substandard products.

[0038] After the fruits and vegetables enter the feeding port from the side of the receiving hopper body 1, the qualified finished products enter the finished product chamber separated by the first buffer 2, and then fall along the finished product falling channel formed by the second buffer 3 and the third buffer 4. In this process, the second buffer 3 and the third buffer 4 can buffer the finished products to avoid direct impact on the receiving hopper body 1, and the unqualified substandard products enter the substandard product chamber, first contacting the baffle 6 at the upper part of the substandard product falling channel. The baffle 6 first pre-buffers the substandard products to slow down their falling speed, and then the substandard products continue to fall along the substandard product falling channel formed by the first buffer 2 and the two fourth buffers 5. The first buffer 2 and the fourth buffer 5 further buffer to reduce the damage rate of the substandard products. This design realizes effective separation of finished products and substandard products and reduces damage to fruits and vegetables in the falling process in all directions. At the same time, due to the same structure and different sizes of the buffers, the buffers can be adapted according to the chamber space and the characteristics of fruits and vegetables to improve the pertinence and effectiveness of the buffers.

[0039] In this embodiment, the first buffer 2 includes two loading square tubes 21, a first guide roller 22, a second guide roller 23, a buffer belt 24, and an adjusting part 25. The two loading square tubes 21 are inclinedly arranged in the receiving hopper body 1. One end of each of the two loading square tubes 21 is provided with a first side lug 211. The first guide roller 22 is installed between the two first side lugs 211. The other end of each of the two loading square tubes 21 is provided with the adjusting part 25. The second guide roller 23 is installed between the two adjusting parts 25. The buffer belt 24 is sleeved on the first guide roller 22 and the second guide roller 23. The adjusting part 25 is used to adjust the distance between the second guide roller 23 and the first guide roller 22 to change the tightness of the buffer belt 24.

[0040] When the fruits and vegetables impact the buffer belt 24, the buffer belt 24 will deform to a certain extent to absorb the impact force of the falling fruits and vegetables, thereby playing a role of elastic buffering. At the same time, by adjusting the distance between the second guide roller 23 and the first guide roller 22 through the adjusting part 25, the tightness of the buffer belt 24 can be adjusted. Different tightnesses result in different elasticity and deformation capabilities of the buffer belt 24, which can adapt to fruits and vegetables of different weights and different skin hardnesses to ensure good buffering effect on various fruits and vegetables and further reduce the damage rate of the fruits and vegetables.

[0041] The adjusting part 25 comprises a second side lug 251, a bolt 252, a first nut 253 and a second nut 254. The other ends of the two loading square tubes 21 are internally fixed with the second nuts 254. The two bolts 252 are respectively threaded through the two second nuts 254. The two second side lugs 251 are respectively sleeved on the two bolts 252. The first nut 253 is threaded on the bolt 252 and abuts against the second side lug 251 to limit the position of the second side lug 251. The second guide roller 23 is installed between the two second side lugs 251.

[0042] When the tightness of the buffer belt 24 is adjusted, the first nut 253 is loosened first. The bolt 252 is rotated and moves along the axial direction under the action of the second nut 254. The second side lug 251 sleeved on the bolt 252 changes the position along with the movement of the bolt 252. The second guide roller 23 installed between the two second side lugs 251 is moved. The distance between the second guide roller 23 and the first guide roller 22 is adjusted. When the position of the second guide roller 23 is adjusted to the appropriate position, the first nut 253 is tightened. The first nut 253 abuts against the second side lug 251 to fix the positions of the second side lug 251 and the second guide roller 23. The tightness of the buffer belt 24 is stable. The adjusting mode is simple in structure and convenient to operate. The movement distance of the second guide roller 23 can be controlled. The accuracy of the tightness adjustment of the buffer belt 24 is ensured. The stability of the buffer effect is ensured.

[0043] It should be noted that the installation mode between the first guide roller 22 and the two first side lugs 211 can be selected as fixed installation or rotating installation. The installation mode between the second guide roller 23 and the two second side lugs 251 can also be selected as fixed installation or rotating installation.

[0044] In the embodiment, the outer periphery of the first guide roller 22 and the second guide roller 23 is covered with soft glue. The inner side of the buffer belt 24 is tightly matched with the soft glue. When the buffer belt 24 is sleeved on the guide roller, the inner side of the buffer belt 24 is tightly matched with the soft glue. The soft glue can increase the friction force between the buffer belt 24 and the guide roller to prevent the buffer belt 24 from slipping on the guide roller. When the fruits and vegetables hit the buffer belt 24, the deformation of the buffer belt 24 drives the soft glue on the outer periphery of the guide roller to also deform. The soft glue further absorbs the impact force to play a double buffering role with the buffer belt 24 to reduce the impact force received by the fruits and vegetables and reduce the possibility of damage to the skin of the fruits and vegetables. In addition, the soft glue is soft in material and will not cause wear to the buffer belt 24. The service life of the buffer belt 24 can be prolonged. The maintenance cost of the equipment is reduced.

[0045] In this embodiment, multiple arc-shaped openings 102 are formed on both sides of the receiving hopper body 1, and the multiple arc-shaped openings 102 correspond to the first buffer 2, the second buffer 3, the third buffer 4, and the fourth buffer 5, so as to fix the installation angle of the first buffer 2, the second buffer 3, the third buffer 4, and the fourth buffer 5 through the screw. The two loading square tubes 21 are provided with screw holes on the sides away from each other, so as to be installed in cooperation with the screw.

[0046] When installing each buffer, the screw is passed through the arc-shaped opening 102 corresponding to the buffer on the side of the receiving hopper body 1, and then screwed into the screw hole on the loading square tube 21 of the first buffer 2. Since the arc-shaped opening 102 is arc-shaped, the angle of the buffer can be adjusted along the arc direction of the arc-shaped opening 102 before the screw is tightened. When the angle of the first buffer 2 is adjusted to the most suitable position for the fruit and vegetable buffer to fall, the screw is tightened, so as to fix the angle of the first buffer 2. The remaining second buffer 3, third buffer 4, and fourth buffer 5 can be adjusted in the above-mentioned manner. This design allows the inclination angle of each buffer to be flexibly adjusted according to the falling trajectory and buffer requirements of different types of fruits and vegetables, so that the buffer can more accurately receive the falling fruits and vegetables, improve the buffer effect, and reduce the damage to the fruits and vegetables.

[0047] In this embodiment, the curtain piece 6 includes a first curtain body 61, a second curtain body 62, and a loading part 63. The loading part 63 is installed on the top wall in the receiving hopper body 1 and located in the upper region of the substandard product falling channel. The first curtain body 61 and the second curtain body 62 are respectively installed on both sides of the loading part 63. When the substandard fruits and vegetables enter the substandard product chamber and fall to the substandard product falling channel, they will first contact the first curtain body 61 and the second curtain body 62 of the curtain piece 6. The first curtain body 61 and the second curtain body 62 can block the falling substandard fruits and vegetables, slow down their falling speed, and achieve pre-buffering. Since the first curtain body 61 and the second curtain body 62 are respectively located on both sides of the loading part 63, they can buffer the substandard fruits and vegetables from both sides, avoid the substandard fruits and vegetables from rolling and colliding due to uneven force on one side, and further reduce the damage.

[0048] In this embodiment, the loading part 63 includes a loading frame 631 installed on the top wall in the receiving hopper body 1. The two sides of the loading frame 631 are respectively provided with a fixed plate 632. The first curtain body 61 and the second curtain body 62 are respectively fixed on the two fixed plates 632. The fixed plates 632 installed on both sides of the loading frame 631 provide reliable fixing positions for the first curtain body 61 and the second curtain body 62. By fixing the first curtain body 61 and the second curtain body 62 on the two fixed plates 632, the installation firmness of the first curtain body 61 and the second curtain body 62 can be ensured, and the first curtain body 61 and the second curtain body 62 can be prevented from falling off when they are hit by fruits and vegetables.

[0049] In the embodiment, the two sides of the receiving hopper body 1 are provided with supports 101 for fixing with the color sorter.

[0050] The specific working principle of the present application is as follows:

[0051] After the fruits and vegetables enter the receiving hopper body 1 from the feed inlet, the qualified finished products enter the finished product chamber separated by the first buffer 2, and the finished product fruits and vegetables fall along the finished product falling channel formed by the second buffer 3 and the third buffer 4, and in the falling process, the second buffer 3 and the third buffer 4 play a role of elastic buffering, absorbing the falling impact force of the fruits and vegetables, and avoiding damage to the finished product fruits and vegetables.

[0052] The unqualified substandard fruits and vegetables enter the substandard product chamber, first contact the first curtain body 61 and the second curtain body 62 located in the upper region of the substandard product falling channel, and the first curtain body 61 and the second curtain body 62 pre-buffer the substandard fruits and vegetables to slow down the falling speed.

[0053] The pre-buffered substandard fruits and vegetables then fall along the substandard product falling channel formed by the first buffer 2 and two sequentially inclined fourth buffers 5, and the buffer belt 24 on the first buffer 2 can buffer the falling fruits and vegetables, and since the first buffer 2, the second buffer 3, the third buffer 4 and the fourth buffer 5 are of the same structure, the belt structure on them also buffers the substandard fruits and vegetables, further reducing the breakage rate of the substandard fruits and vegetables.

[0054] The above describes the embodiment of the present application, but the embodiment is not limited to the specific implementation described above, and the specific implementation described above is only illustrative, not restrictive, and those skilled in the art can make many forms under the inspiration of the embodiment, which all belong to the protection of the embodiment.
