Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product sorting, and specifically relates to a belt conveyor device capable of realizing uniform arrangement of materials. Background Art

[0002] With the improvement of people's living quality, the requirements for daily vegetables, fruits, etc. are also changing. The tastes in different regions are different. For example, people in some regions like apples with a crispy texture, while people in some other regions like apples with a softer texture. People in northern regions prefer larger apples, and people in Shanghai like smaller apples. For targeted sales, the need for grading and classifying agricultural products is becoming increasingly obvious.

[0003] In the scenario of grading and sorting, it is often required that materials be evenly arranged on the conveyor belt, which is beneficial for the vision system to identify, and is also beneficial for the actuator to perform grading and sorting. It can greatly reduce the carry-out rate of grading and sorting and improve the accuracy of execution. Therefore, there is an urgent need for a belt conveyor device capable of realizing uniform arrangement of materials. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a belt conveyor device capable of realizing uniform arrangement of materials.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0006] A belt conveyor device capable of realizing uniform arrangement of materials includes a base frame, a stepped belt, a driving motor, a material buffer hopper, and a discharge baffle arranged on the base frame;

[0007] The stepped belt is inclinedly installed on the base frame through rollers. The material buffer hopper is located below the stepped belt. The driving motor is in transmission connection with the rollers of the stepped belt. The discharge baffle is arranged at the discharge port position of the material buffer hopper;

[0008] On the stepped belt, a plurality of chevron stepped arrays are arranged at equal intervals along the length direction of the belt. The form of each chevron stepped array is: including a top step located at the middle top position, and N side steps gradually arranged downward and outward on the left and right sides of the top step; the upper surface of the stepped belt is a guiding inclined surface gradually inclined from the middle to the left and right sides.

[0009] In the above technical solution, the numerical value of N is 4 - 6.

[0010] In the above technical solution, side baffles are arranged on the base frame. The side baffles are located on both sides of the stepped belt and are used to prevent materials from slipping out of the stepped belt from the sides.

[0011] In the above technical solution, a limiting protrusion is set at the upper outer side position of the outermost side step of each herringbone step array. The limiting protrusion is used to limit the material from moving outward so that the material is stably located on the outermost side step. At the same time, it prevents the material on the outermost side step from rubbing and colliding with the side baffle during the operation of the step belt, thereby preventing damage to the material.

[0012] In the above technical solution, the discharge baffle is installed on the base frame through a height adjustment structure, so that the height of the discharge baffle is adjustable, thereby adapting to the size of the material by adjusting the height of the discharge baffle to achieve the best effect.

[0013] In the above technical solution, liftable support wheels are respectively arranged at the four top corners of the bottom of the base frame.

[0014] In the above technical solution, the liftable support wheel is composed of a hand-cranked lift support leg and a wheel with a brake function is installed at the bottom of the hand-cranked lift support leg.

[0015] In the above technical solution, the inclination angle of the step belt is adjusted by adjusting the height difference between the two liftable support wheels on the front side and the two liftable support wheels on the rear side to achieve the optimal use effect.

[0016] In the above technical scheme, the structure of each step of the herringbone step array is: including a bottom supporting basic frame, a top flexible surface layer and an intermediate sponge filling layer, the bottom supporting basic frame is made of plastic material, and the top flexible surface layer is made of fiber cloth; the technical function of this structure is: when the material falls on the step, the intermediate sponge filling layer can buffer the material and reduce the collision damage to the material. On the other hand, due to the compressibility of the intermediate sponge filling layer, the position of the intermediate sponge filling layer at the bottom of the material is recessed, so that the material can be stably placed on the step, reducing the shaking of the material during the transmission process, thereby also reducing the damage caused by repeated shaking and collision of the material.

[0017] The method of using the belt conveyor device provided by the present invention for achieving uniform arrangement of materials is as follows:

[0018] The material is loaded into the material buffer bucket, and the driving motor drives the step belt to run from bottom to top along the inclined direction. During the operation of the step belt, the herringbone step array on the step belt drives the material to move obliquely upward. Under the action of the discharge baffle, only one layer of material can pass through the step belt, and the excess material is pushed downward. At the same time, under the action of gravity, the herringbone step array on the step belt and the guide slope, the material rolls downward to both sides, so that the material is evenly arranged on the herringbone step array of the step belt.

[0019] The advantages and beneficial effects of the present invention are:

[0020] 1. The present invention adopts an inclined belt form, and a herringbone step array is arranged at equal intervals along the length direction of the belt (i.e., along the circumferential direction of the belt's operation). Moreover, the upper surface of the belt is a guiding inclined plane that gradually inclines from the middle to the left and right sides. In this way, during the operation of the belt, the herringbone step array on the belt drives the material to move obliquely upward. Combining with the function of the discharge baffle, only one layer of material can pass through on the stepped belt. Under the combined action of gravity, the herringbone step array, and the guiding inclined plane, the material rolls downward to both sides, realizing the uniform arrangement of the material on the herringbone step array of the belt. The present invention does not need to add other auxiliary equipment, can shorten the length of the production line, and save costs.

[0021] 2. The present invention sets a limit protrusion at the upper outer position of the outermost side step of each herringbone step array. This limit protrusion is used to limit the outward movement of the material, so that the material is stably located on the outermost side step. At the same time, it avoids the friction and collision between the material on the outermost side step and the side baffle during the operation of the stepped belt, causing damage to the material.

[0022] 3. The structure of each step of the herringbone step array of the present invention is: including a bottom support basic frame, a top flexible surface layer, and an intermediate sponge filling layer. The bottom support basic frame is made of plastic material, and the top flexible surface layer is made of fiber cloth. The technical effect of this structure is: when the material falls on the step, the intermediate sponge filling layer can play a buffering role for the material, reducing the collision damage to the material. On the other hand, due to the compressibility of the intermediate sponge filling layer, a depression is formed at the position of the intermediate sponge filling layer at the bottom of the material, so that the material can be stably placed on the step, reducing the shaking of the material during transmission, and thus also reducing the damage caused by the repeated shaking and collision of the material.

[0023] 4. The discharge baffle of the present invention is installed on the base frame through a height adjustment structure, so that the height of the discharge baffle is adjustable, and thus the height of the discharge baffle is adjusted to adapt to the size of the material to achieve the best effect.

[0024] 5. The present invention respectively sets liftable support wheels at the four top corner positions of the bottom of the base frame, so that the whole device can be conveniently moved, and the height of the whole device can also be adjusted to make the top discharge position of the stepped belt dock with the target position. In addition, the inclination angle of the stepped belt can be adjusted by adjusting the height difference between the two liftable support wheels at the front side and the two liftable support wheels at the rear side to achieve the optimal use effect.

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0031] Embodiment 1

[0032] Refer to the attached Figure 1 , a belt conveyor device capable of achieving uniform material layout, including a base frame 1 and a stepped belt 2, a driving motor 3, a material buffer hopper 4 and a discharge baffle 5 arranged on the base frame 1.

[0033] The stepped belt 2 is inclinedly installed on the base frame 1 through rollers. The material buffer hopper 4 is located below the stepped belt 2. The driving motor 3 is in transmission connection with the rollers of the stepped belt 2 to drive the stepped belt 2 to operate. The discharge baffle 5 is arranged at the discharge port position of the material buffer hopper 4 to limit that only one layer of material can pass through the outlet of the material buffer hopper 4.

[0034] On the stepped belt 2, a plurality of chevron step arrays 21 are arranged at equal intervals along the length direction of the belt (i.e., along the circumferential direction of the belt operation). Refer to the attached Figure 2 , and the form of each chevron step array 21 is: including a top step 211 located at the middle top position, and N side steps 212 gradually arranged downward and outward on the left and right sides of the top step. Preferably, the value of N is 4 - 6. In this embodiment, the value of N is 5.

[0035] Furthermore, refer to the attached Figure 3 , the upper surface of the stepped belt 2 is a guiding inclined surface 23 that gradually inclines from the middle to the left and right sides, so that the material can roll better to both sides during the conveying process.

[0036] Furthermore, side baffles 101 are provided on the base frame 1. The side baffles 101 are located on both sides of the stepped belt 2 and are used to prevent materials from falling out of the stepped belt 2 from the sides. Preferably, limit protrusions 213 can also be provided at the upper outer positions of the outermost side stepped portions of each herringbone stepped array 21. The limit protrusions 213 are used to limit the outward movement of the materials, so that the materials 8 are stably located on the outermost side stepped portions. At the same time, during the operation of the stepped belt 2, the materials 8 on the outermost side stepped portions are prevented from rubbing and colliding with the side baffles 101, thus avoiding damage to the materials 8.

[0037] During operation, materials (such as fruits like apples, pears, or oranges) are loaded into the material buffer hopper 4. The stepped belt 2 is driven by the drive motor 3 to run upward along the inclined direction from bottom to top. During the operation of the stepped belt 2, the herringbone stepped array 21 on the stepped belt 2 drives the materials to move obliquely upward. Under the action of the discharge baffle 5 at the outlet of the material buffer hopper 4, only one layer of materials can pass through the stepped belt, and the excess materials are deflected downward. At the same time, under the combined action of gravity, the herringbone stepped array 21 on the stepped belt 2, and the guiding inclined surface 23, the materials roll downward to both sides, realizing the uniform arrangement of the materials on the herringbone stepped array 21 of the stepped belt (see attached Figure 2 ).

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, further, the discharge baffle 5 is installed on the base frame 1 through a height adjustment structure, so that the height of the discharge baffle 5 is adjustable (i.e., the distance between the discharge baffle 5 and the surface of the stepped belt is adjusted), thereby adapting to the size of the materials by adjusting the height of the discharge baffle 5 to achieve the best effect.

[0040] Embodiment 3

[0041] On the basis of Embodiment 1, further, liftable support wheels 102 are respectively provided at the four top corner positions of the bottom of the base frame 1. Preferably, the liftable support wheels are composed of hand-cranked lift legs and wheels with braking functions installed at the bottoms of the hand-cranked lift legs. This enables the convenient movement of the entire device and also the adjustment of the height of the entire device, so that the top discharge position of the stepped belt 2 can be docked with the target position. In addition, the inclination angle of the stepped belt 2 can be adjusted by adjusting the height difference between the two liftable support wheels 102 at the front side and the two liftable support wheels 102 at the rear side to achieve the optimal use effect.

[0042] Embodiment 4

[0043] On the basis of Embodiment 1, further, see attached Figure 4, the structure of each step of the chevron step array 21 (i.e., each top step 211 and side step 212) is as follows: it includes a bottom support base frame 201, a top flexible surface layer 202, and an intermediate sponge filling layer 203. The bottom support base frame 201 is made of plastic material, and the top flexible surface layer 202 is made of fiber cloth. The technical effect of this structure is that when the material falls on the step, the intermediate sponge filling layer 203 can buffer the material, reducing the collision damage to the material. On the other hand, due to the compressibility of the intermediate sponge filling layer 203, a depression is formed at the position of the intermediate sponge filling layer 203 at the bottom of the material, so that the material can be stably placed on the step, reducing the shaking of the material during the conveying process, and thus also reducing the damage caused by the repeated shaking and collision of the material.

[0044] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0045] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0046] The above is an exemplary description of the present invention. It should be noted that without departing from the core of the present invention, any simple deformation, modification, or equivalent replacement that can be made by those skilled in the art without creative labor falls within the protection scope of the present invention.
