A 15mm through hole is arranged at a relative position between the baffle and the core removal tool 10, which is 10mm larger than the diameter of the core removal tool 10.

[0048] Specifically, its structure is composed of a feed orienting device 1, a conveying and pitting device 2, a collecting device 3, a frame 4, a feed hopper 5, a differential directional conveyor belt 6, a differential directional clamp 7, a transmission mechanism 8, a material tray 9, a pitting tool 10, a crank rocker mechanism 11 and a speed mechanism 12 to form a high-efficiency apricot pitting device. The high-efficiency apricot pitting device can improve the productivity of apricot pitting, liberate labor, increase the economic benefits of fruit farmers, and realize a series of processes such as conveying, pitting and collecting of the mainstream local specialty apricot fruits in Xinjiang, so that the whole can efficiently complete the separation of apricot pulp and apricot pits and minimize the damage of the pulp; the working process of the pitting machine should reduce the participation of workers as much as possible, the efficiency should be higher than that of manual operation, the degree of mechanization should be high, and a series of processes such as conveying, orienting and pitting can be automatically completed.

[0049] like Figure 1-4As shown, during the apricot pitting process, a part of the apricots are transported to the spatial orientation mechanism through the feed port for orientation processing, and then the apricots that have been spatially oriented are transported to the cutting area through the tray conveying mechanism for pitting. Finally, the tool pokes the apricot pit out from the bottom of the tray and drops it into the pit collection area through the inclined surface. The pulp falls from the tray through the inclined surface into the pulp collection area, thereby completing the pitting of the apricots. The apricot pitting machine is composed of a feed orientation device 1, a conveying pitting device 2, a collection device 3, a frame 4 and other parts. The differential orientation device mainly realizes the orientation and alignment of the apricots to prepare for the next stage of pitting. The conveying pitting device mainly completes the conveying and pitting of the apricots, so that the apricots and apricot pits are separated. Through the gear transmission and the crank rocker mechanism, the motor power is transformed into the power source of the entire machine. The frame 4 and other parts support and position the entire equipment. Protective protection.

[0050] Working principle: First, apricots enter the dynamic differential orientation device differential orientation conveyor belt 6 and differential orientation fixture 7 in turn through the feeding hole of the feeding funnel 5: Due to the large difference in the three-axis dimensions of the apricots, the apricots are symmetrical along the saddle surface. When the fresh apricots perform a specific rigid body motion, due to the physical property of "minimum spatial geometric force", under the constraint of the minimum space, the object will constantly adjust its posture to achieve the minimum space. That is, because the radial dimension of the apricots perpendicular to the saddle surface is small, differential space orientation can be completed. After the orientation is completed, the saddle line of the apricots is straightened, and then opened at the end of the differential orientation fixture 7, which is designed for intermittent continuity, so the conveying roller is designed as a polygonal roller conveyor belt. In the process of pitting apricots, the pitting punch needs to continuously perform reciprocating linear motion, so the rotary motion of the motor is converted into the reciprocating linear motion of the pitting tool 10 through the crank rocker mechanism 11, so as to achieve the purpose of pitting. After pitting is completed, the apricot pits are collected through the pitting channel, and the apricot flesh falls into the collection box of the collection device 3 under the action of gravity along the conveyor belt.

[0051] like Figure 5-6As shown, the feed orienting device 1 consists of three parts: a feed hopper 5, a differential orienting fixture 7 and a differential orienting conveyor belt 6. It mainly allows apricot fruits to fall into the automatic orienting device from the lower port of the feed hopper 5 in sequence, and complete the automatic orientation of the apricot fruits through the differential orienting fixture 7. After reaching the end of the orienting device, the apricot fruits fall into the next conveying and pitting device 2 in sequence through the discharge port at the end of the orienting device. The feed hopper 5 mainly functions to store apricot fruits and allows the apricot fruits to fall into the differential orienting fixture 7 in sequence. The size of the apricot fruits is determined by the geometric characteristics of the apricot fruits and the directional entrainment. The purpose of the through hole is to cooperate with the directional entrainment feed port to enable the apricot fruits to enter the directional channel in sequence. The material is aluminum alloy and its capacity is approximately 0.2m3, which can meet the actual production needs. The uppermost end of the mechanism that cooperates with the feed hopper 5 is provided with a hollow cylinder with an inner diameter of 50mm and an outer diameter of 60mm, which can be used with the feed. The funnel 5 is matched with the feeding port and also supports the feeding funnel 5. The apricots enter the differential directional clamp 7 from the opening below the feeding funnel 5 in turn. The transverse diameters of the two types of apricots are in the range of 34 to 38 mm. When the inlet width of the supporting conveyor belt is 30 mm, the conveyor belt speed is 1.29 m / s, the minimum effective distance for directional conveying of fresh apricots is 1.16 m, and the transverse diameter of the apricot fruit is 34 to 35 mm, it is a better combination, and the success rate of apricot orientation is relatively high. The side plate supports of the differential directional clamp 7 can be connected to the directional clamp by welding. At the same time, the side plates mainly support it and are fixed to the frame with bolts and nuts. At the same time, the inlet width of the supporting conveyor belt of the differential directional mechanism is 30 mm. Four channels are differentially oriented at the same time. Four apricots can be oriented at a time. The interval between each channel is 10 mm, which meets the required design size of the apricot orienting device and can complete the apricot orientation function. The overall height of the mechanism is 50mm. After removing the thickness of the top plate, the total height of the effective working space is 45mm, which can effectively ensure the transportation of single-layer apricots while avoiding blockage caused by accumulation of fresh apricots at the entrance and exit of the automatic orienting area. When the apricots have completed orientation and passed to the end of the channel, they will fall steadily into the material holding tray 9 above the conveyor belt through the discharge port designed at the end of the device. The specific size of the end discharge port is a 50mm through hole, which is arranged at the end outlet where the orientation is completed, ensuring that the successfully oriented apricots fall in turn without causing blockage or deflection of the successfully oriented apricots. When the conveyor belt speed of the differential oriented conveyor belt 6 is 1.29m / s, it is the best combination, and the success rate of apricot orientation is high. In order to save costs, a conveyor belt system that meets the size requirements can be directly customized, which is low-cost and convenient for maintenance and replacement.

[0052] The conveying and pitting device 2 is generally composed of five major parts: a material receiving tray 9, a pitting tool 10, a crank rocker mechanism 11, a transmission mechanism and a fruit pit collecting device. It is the most important mechanism in the entire mechanical equipment. Through the mutual cooperation of various mechanisms, the perfect realization of various functions in its working process is ensured. The design of the discharge port size of the apricot directional channel, the conveying speed of the conveyor belt and the material receiving tray 9 can make the apricot fruits stably placed on the material receiving tray 9, effectively preventing the apricot fruits from deflecting. At the same time, the smooth curved surface design can effectively prevent the apricot fruits from getting stuck on the tray during pitting. The spacing between each material receiving hole is 120mm. At the same time, there is a through hole with a diameter of 15mm from the center of the material receiving hole to the middle of the material receiving tray. Through this through hole, the apricot kernel can fall, and the apricot fruit falls to the pulp collection area along the conveyor belt by gravity. The function of the thread of the pitting tool 10 is to fix it on the frame 4 through the cooperation of the thread and the nut. At the same time, its height can be adjusted according to actual production needs. The core removal tool 10 is convenient for adjustment and tool changing. The end of the core removal tool 10 is smoothly concavely designed to effectively prevent the core or pulp from being stuck on the core removal tool 10, resulting in the inability to complete the corresponding core removal function and causing damage to the tool and the machine. The main function of the crank rocker mechanism 11 is to convert the circular motion of the working motor into the up and down reciprocating motion of the core removal tool through the crank rocker. The working process of this mechanism requires the mutual cooperation of the entire system. The rotation radius of the crank of the crank rocker mechanism 11 is 65mm, and its size is relatively small. Therefore, it is designed to be disc-shaped this time, and the thickness of the disc is determined to be 10mm. There is a boss with a diameter of 25mm between the round pin and the disc. The purpose is to prevent interference with the crank shaft during its movement. Therefore, the boss is designed to have a height of 10mm, the diameter of the round pin is 15mm, the distance between its center and the center of the disc is 65mm, and the length of the round pin is 15mm, which is slightly larger than the thickness of the connecting rod to prevent deflection and falling off during movement. At the same time, in order to ensure the accurate positioning of the crank and the transmission shaft, a 20mm boss is given to the right end, and a positioning pin is used to position it through the opening. Because the effective bearing area of ​​the device is relatively small, it is easy to produce stress concentration. Therefore, cast iron is selected as the material, which has excellent vibration reduction, low notch sensitivity and high wear resistance.The speed design of the crank rocker mechanism 11 needs to refer to the working environment and working requirements. The working speed is set to 40r / min. A reduction motor is selected. The main function of the reduction motor is to reduce the speed of the prime mover and increase the output torque to match the speed and torque requirements of the working machine or actuator. It is widely used in low-speed and high-torque drive equipment to meet the requirements of this use. The selected reduction motor model is GL40-2200W3~40. The output speed of the motor is 40r / min, and the motor and the crank shaft are connected through a plum blossom coupling to complete the corresponding transmission conversion. The motor should check the position where the motor shaft is connected to the crank, which is connected by a plum blossom coupling. The plum blossom coupling The allowable torque is 25N / m~12500N / m, the output torque of the motor is 40N / m, the transmission torque is 40N / m, the allowable shear stress of the shaft is =40MPa, the total length of the shaft is 185mm, the shaft twist foot does not exceed the full length, the shear modulus of steel is 8×104MPa, the minimum diameter of the shaft is 25mm, which meets the verification requirements, and the speed of the crank of the transmission mechanism 8 is 40r / min, that is, it takes 1.5S to turn a circle. Each time the punch punches two rows of material trays 9, because the material tray 9 is designed for intermittent continuity, the conveying roller is designed as a polygonal roller conveyor belt. This design can be achieved by customizing the polyurethane rubber roller, and the conveyor belt roller is designed as a 12-sided polygon. Punching two rows of material trays 9 requires the conveyor belt to rotate 1 / 6 of a circle. Assume that the conveyor belt roller speed is also 40r / min, through an intermittent gear mechanism, the two gear ratios are 1, the modulus is 2, the number of teeth is 120, and the ratio of the design movement time and stop time is 1:5, that is, within 1.5s, 0.25s to turn 1 / 6 circle, 1.25s conveyor belt does not move. After verification, the height of the tool falling within 0.25s has no effect on the conveyor belt, so the intermittent gear mechanism is feasible. At the same time, the conveyor belt is made of PVC belt, and the conveyor belt can be connected to the material tray 9 by vulcanization.

[0053] like Figure 6As shown, the main function of the collecting device 3 is to collect the removed apricot kernels and apricot meat, which is convenient for the next processing and prevents them from affecting the operation of the machine. Other parts include a frame 4 and selected standard parts. The frame provides support and positioning for each mechanism of the entire machine, and the remaining standard parts play a role in connection and positioning support, and are convenient for replacement, thereby reducing production costs. Through the cooperation of the fruit kernel collecting device and the conveying mechanism 8, when the pitting tool 10 moves downward, the pitting tool 10 punches the apricot kernel out of the through hole of the material tray 9 and the conveyor belt, and passes through the collecting device 3, following the slope, and is discharged from the side of the device, thereby preventing the apricot kernel from affecting the operation of the equipment. The collecting device 3 can effectively prevent the tool from colliding with the baffle. At the same time, when the punching knife punches away the apricot kernel, due to the interaction of forces, it is possible that the apricot meat adheres to the punching knife, and the attached apricot meat is blocked by the baffle above, so that the attached flesh can fall off. Prevent the impact on the next punching operation and protect the device at the same time. After falling off, the apricot meat falls into the material tray 9, and as the conveyor belt continues to move forward, it gradually enters the back of the conveyor belt, and with the effect of gravity, falls into the apricot meat collection device 3 in front. At the same time, during the core-punching operation, the deformation of the conveyor belt should also be considered to determine whether it will affect the accuracy of the machine's core-punching and whether it will cause damage to the conveyor belt. Therefore, in order to prevent the transmission belt from being deformed and affecting the mechanical work due to the interaction of forces when the punching knife is removing the core, three rib baffles are designed in the middle of the fruit core collection device 3 below the conveyor belt. Since the material tray 9 is hard, when the knife punches the core downward, the three rib baffles can support and lift the material tray 9, hold up the conveyor belt, and prevent the conveyor belt from being greatly deformed and affecting the working accuracy. The punching knife can punch the core accurately without deforming or damaging the conveyor belt. The collection device 3 box can accommodate 3,200 core-punched apricots, which can meet basic production needs, and can also be modified as needed until it meets its own needs. The frame 4 carries various movable parts and components of the machine. The function of the frame 4 is to fix and support the various parts of the machine so that the machine can operate normally. The quality and stability of the frame 4 directly affect the performance and life of the machine, and provide structural support for the machine. The frame 4 is usually made of steel or aluminum, with high strength and rigidity. The design of the frame 4 must take into account factors such as the weight, size and operating environment of the machine to ensure that the frame 4 can withstand the weight of the machine and the vibration and impact force during operation. The main function of the highest point of the frame 4 is to provide support for the feeding funnel 5. The threaded holes above the frame 4 are connected to the working parts of other key mechanisms through bolts and nuts to support the entire frame.There is a through plate at the bottom. Considering that the whole frame 4 is too long, two supports are added on both sides in the middle to fix the strength of the whole frame 4. The frame 4 supports the motor. At the same time, the apricot meat collecting device 3 is also placed above the base of the frame 4. Considering the difficulty of processing during the design process, the connecting rods are mainly aluminum alloy rods, which can reduce the weight of the whole machine. At the same time, the manufacturing of the whole mechanism can be completed by welding, which reduces the production cost. The various mechanisms of the efficient apricot pitting device are connected and fixed to the frame 4 by bolts and nuts. At this time, the bolts are mainly subjected to lateral loads. The diameter of the selected bolts is 10mm, and the material is Q235 steel. A total of 14 ordinary bolts of M10 bolts are used. The performance of the bolts is 4.6. It is estimated that the average lateral load of each bolt is 800N. By selecting standard parts, the machine manufacturing can be reduced, and it is also convenient to replace damaged parts to ensure production efficiency. The standard parts used in the efficient apricot pitting device mainly include flat keys, deep groove ball bearings, bearing supports, bolts, nuts, etc.

[0054] Through the efficient apricot pitting device, on the basis of collecting and mastering the mainstream apricot pitting machines on the market, and referring to other pitting methods for nuclear fruits, we have learned from each other's strengths and weaknesses, and designed the overall design plan of the fully automatic apricot pitting machine. Through the four-channel apricot automatic orientation device, the automatic orientation of the apricots can be realized, which is convenient for the later pitting process, while reducing manual participation, reducing labor intensity, and improving production efficiency. According to the external dimensions of Saimati apricots and Mingxing apricots and the reasonable configuration of the feeding components, the size of the material holding hole and the tray is determined. The corresponding gear intermittent mechanism is designed to cooperate with the core-punching crank rocker mechanism to achieve the relative stillness of the up and down reciprocating motion of the punching knife and the movement of the transmission belt during the core-punching process, so that a safe and smooth pitting operation can be achieved. The working efficiency can reach 19,200 pieces / hour, effectively achieving the advantages of high degree of automation, high work efficiency, high pitting rate, simple and compact structure, low cost, and strong applicability.
