Description

Technical Field

[0001] The utility model relates to the field of coconut processing, and particularly relates to a discharging device for coconut shell recycling. Background Art

[0002] In the processing process of coconut juice and coconut fruit beverages, it is necessary to take out the coconut meat from the coconut shell to obtain two products, namely coconut meat and coconut shell. The coconut meat is used for the subsequent processing of coconut juice and coconut fruit beverages, while the coconut shell is collected and sold to downstream manufacturing enterprises for making various products such as coconut shell handicrafts and coconut shell charcoal. The properties and selling prices of the coconut shell raw materials required for making coconut shell handicrafts and coconut shell charcoal are also different. Therefore, how to effectively classify, collect and sell the peeled coconut shells is one of the methods to improve the enterprise's benefits and reduce production costs.

[0003] At present, after the coconut shell is peeled off, it will directly fall onto the conveyor belt below and be directly conveyed to the rear for processing, and then be packaged into a collection box after processing. The existing factory processing method is to arrange personnel beside the conveyor belt to sort out the relatively complete coconut shells, and let the broken coconut shells continue to be conveyed backward along the conveyor belt. After the number of sorted relatively complete coconut shells is sufficient, the sorting is stopped, and all coconut shells are directly collected as broken coconut shells. However, this discharging and processing method for coconut shells has low efficiency and low utilization rate of human resources. At the same time, when the relatively complete coconut shells are collected together with the broken coconut shells, the space occupied by them is large, resulting in a decrease in the storage density of coconut shells per unit volume of the collection box and an increase in transportation costs.

[0004] In view of this, a discharging device for coconut shell recycling is designed, which can automatically screen the relatively complete coconut shells, so that the broken coconut shells and the relatively complete coconut shells can be discharged separately, and when screening is not required, the relatively complete coconut shells can be broken to reduce the storage space occupied by them and improve the storage density. Content of the Utility Model

[0005] The purpose of the utility model is to provide a discharging device for coconut shell recycling to solve the problems described in the background art.

[0006] The technical solution of the utility model is realized as follows:

[0007] A discharging device for coconut shell recycling, comprising a first support, a second support, a third support and a grid sieve frame. A feeding box is provided on the third support. The top of the feeding box is provided with a feeding port and the bottom is open. Two oppositely arranged crushing rollers are rotatably installed in the feeding box. A guide plate is also rotatably provided below the feeding port. A driving mechanism for driving the two crushing rollers to rotate towards each other is further provided outside the feeding box. A deflecting mechanism for controlling the rotation angle of the guide plate is also provided outside the feeding box. When the guide plate rotates to a preset position, the materials entering from the feeding port are guided to the crushing rollers. When the guide plate rotates to another preset position, the materials entering from the feeding port are guided outside the crushing rollers. An inclined discharging plate is provided at the bottom of the feeding box. The grid sieve frame comprises a plurality of circular rods spaced at equal intervals from each other. The plurality of circular rods are parallel to each other and obliquely arranged. The lower ends of the plurality of circular rods are connected to each other through a lower connecting plate. The upper ends of the plurality of circular rods are connected to each other through an upper connecting plate. The lower connecting plate is rotatably installed on the top of the first support. An oscillating mechanism is provided on the top of the second support. The upper connecting plate is drivingly connected to the oscillating mechanism so that the upper end of the grid sieve frame vibrates up and down. The lower end of the discharging plate extends to directly above the grid sieve frame.

[0008] When using the above scheme, the coconut shells on the conveyor belt are conveyed to the feeding port and put in. When it is necessary to screen out relatively complete coconut shells, the angle of the guide plate is controlled by the deflecting mechanism so that the coconut shells do not pass through the crushing rollers and directly fall onto the discharging plate at the bottom of the feeding box. After the discharging plate catches the coconut shells, the coconut shells slide down along the discharging plate onto the grid sieve frame. At the same time, the oscillating mechanism is started. Under the action of gravity, the coconut shells slide down along the circular rods. The crushed coconut shells fall through the intervals between the circular rods, while the relatively complete coconut shells keep sliding to the ends of the circular rods and fall from the ends of the grid sieve frame. The continuously oscillating grid sieve frame can screen out large but incomplete coconut shells, preventing large but incomplete coconut shells from not being screened out because they are simultaneously propped on two cylinders.

[0009] When it is not necessary to screen out relatively complete coconut shells, the angle of the guide plate is controlled by the deflecting mechanism so that the coconut shells slide towards the crushing rollers. The driving mechanism drives the two crushing rollers to rotate towards each other to crush the coconut shells falling into the crushing rollers into small pieces. The crushed coconut shells fall onto the discharging plate below and slide towards the grid sieve frame and all fall through the intervals between the circular rods of the grid sieve frame.

[0010] This device can automatically screen out relatively complete coconut shells through the grid sieve frame, so that the crushed coconut shells and the relatively complete coconut shells can be discharged separately. And when screening is not required, it can crush the relatively complete coconut shells before discharging, thereby reducing their storage space occupation and increasing the storage density.

[0011] A further technical solution is that a fourth support is further provided on the top of the first support, and a convex plate is fixedly provided on the lower connecting plate. The convex plate is rotatably installed on the fourth support.

[0012] A further technical solution is that a top plate is fixedly provided on the upper connecting plate, and the oscillation mechanism includes a fifth bracket arranged on the top of the second bracket, a second rotating shaft is rotatably mounted on the fifth bracket, a cam and a driven wheel are fixedly sleeved on the second rotating shaft, the cam abuts against the bottom of the top plate, and the oscillation mechanism also includes a first motor fixedly provided on the second bracket, a driving wheel is provided on the output shaft of the first motor, and the driving wheel is drivenly connected to the driven wheel.

[0013] When the above scheme is used, the output shaft of the first motor drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate, the driven wheel drives the rotating shaft to rotate, and the rotating shaft drives the cam to rotate, so that the top plate that abuts against the cam oscillates up and down continuously following the rotation of the cam.

[0014] A further technical solution is that a crushing shaft is provided on the central axis of the crushing roller, one end of the crushing shaft is rotatably installed on the side wall of the discharge box, and the other end of the crushing shaft is rotatably passed through the side wall of the discharge box and passes outward, and the driving mechanism includes a main gear and a secondary gear arranged outside the discharge box, the main gear and the secondary gear are meshed with each other, and the main gear and the secondary gear are respectively fixedly mounted on the two crushing shafts of the two crushing rollers, and the driving mechanism also includes a second motor arranged outside the discharge box, and a driving gear is provided on the output shaft of the second motor, and the driving gear is meshed with the main gear.

[0015] When the above solution is used, the output shaft of the second motor drives the driving gear to rotate, the driving gear drives the main gear to rotate, and the main gear drives the secondary gear to rotate, so that the two crushing shafts rotate towards each other, and the crushing shafts drive the crushing rollers thereon to rotate towards each other.

[0016] A further technical solution is that a first rotating shaft is also provided in the middle of the material guide plate, and the first rotating shaft is rotatably passed through the side wall of the material discharge box and passes outward. The shifting mechanism includes a shifting rod provided outside the material discharge box, and one end of the shifting rod is fixed on the first rotating shaft. The material discharge box is also provided with a limiting mechanism for fixing the shifting rod.

[0017] When the above solution is used, the lever is moved, the lever drives the first rotating shaft to rotate, the first rotating shaft drives the material guide plate to rotate, and the limiting mechanism is used to fix the lever, thereby fixing the material guide plate.

[0018] A further technical solution is that the limiting mechanism includes two positioning holes formed on the side wall of the material discharge box, the lever is also provided with a through hole matching the positioning holes, and a pin for inserting into the positioning hole is slidably penetrated through the through hole.

[0019] A further technical solution is that a feed hopper is connected above the feed port.

[0020] When the above solution is used, after the latch is inserted into the positioning hole, the lever is restricted and cannot rotate.

[0021] The beneficial effects of the utility model are:

[0022] 1. Strong flexibility: By controlling the angle of the material guiding plate through the dialing mechanism, it is possible to flexibly select whether to screen out relatively complete coconut shells or directly crush them to meet different processing requirements.

[0023] 2. High screening efficiency: Using the grid sieve frame and the oscillation mechanism, it is possible to effectively separate relatively complete coconut shells from crushed coconut shells, improving the screening efficiency.

[0024] 3. High degree of automation: The entire processing process has a high degree of automation, reducing the need for manual operation and improving production efficiency. Description of the Drawings
