Description

Technical Field

[0001] The present invention relates to the field of primary walnut processing, and particularly to a machine for continuously peeling green walnuts, belonging to the technical field of agricultural machinery. Background Art

[0002] Since the harvesting period of walnuts is relatively concentrated and the season is short, after the walnut fruits are harvested, the outer green peel must be removed as soon as possible to keep the surface of the hard shell of the walnuts clean. Otherwise, the walnut kernels will mildew, seriously affecting the internal quality of the walnuts. At present, most fruit farmers and large walnut green peel removing processing households in walnut producing areas of our country use manual knife cutting or stick beating methods to remove the green peel, with low production efficiency, high cost, large labor intensity, and incomplete separation of the green peel, resulting in a decline in the grade of walnuts. Mechanized peeling is the key way for the industrial development of walnuts.

[0003] The newly published Chinese patents include: a walnut green peel removing and cleaning machine (Patent No.: 201020550637.5), which uses a drum-type wire brush to brush the green peel and uses pressured water for cleaning. Before use, it is necessary to first adjust the distance between the bottom surface of the wire brush roller and the bottom surface of the grid drum to adapt to the size of the walnuts. Otherwise, walnuts with a smaller shape are not easy to peel, and walnuts with a larger shape are likely to be damaged; too high a speed of the rotating parts will also increase the damage of the walnuts, the productivity is limited by the diameter of the drum, and the peeling rate is also limited by the axial length of the wire brush, etc.

[0004] Another kind of green walnut peeling machine (Patent No.: 201220160189.7) uses a drum-type blade cutting method for peeling and uses a water spray pipe for cleaning. There is a certain gap between the peeling device equipped with blades and the drum grid bars, but this gap is not adjustable, and the extrusion pressure applied to the walnuts is adjusted by a spring. Walnuts with a larger size cannot enter the peeling area, and walnuts with a smaller size are not easy to peel due to the small extrusion pressure, resulting in a reduced peeling rate.

[0005] Due to the wide variety of walnut varieties in our country, irregular shapes, large differences in external dimensions, large differences in the thickness and strength of the hard shells of walnuts, and different degrees of maturity after walnut harvesting, the peeling effect is not ideal during the mechanical peeling process of walnuts. Summary of the Invention

[0006] The purpose of the present invention is to provide a vertical green walnut peeling machine, which has a reasonable structure, high reliability, strong adaptability, low cost, and can be used in batch production in complete sets of equipment. This machine can conveniently adjust the gap of the peeling space and the angle balance of the peeling space (the angle between the brush plate and the mounting plate surface of the knife holder), and can realize the extrusion and cutting process of green walnuts from large to small twice.

[0007] The object of the present invention is achieved as follows: The vertical green walnut peeling machine consists of a frame body device, a tool rest device, a gap adjusting device, and a brush and balance adjusting device. It is characterized in that: for the said frame body device, the tool rest device is installed on the frame. The tool rest device includes a blade mounting disc, on which U-shaped blades are fixed. The blade mounting disc is driven by a motor reducer. There is a cylindrical body connected to the frame above the blade mounting disc. A feed hopper is provided at the upper part of the body. An outlet is opened on the side wall of the lower part of the body and connected to a discharge port. A guide plate is arranged on one side near the discharge port inside the body. The upper part of the body is connected with a brush and balance adjusting device. The relative movement formed by the rotation of the blade mounting disc under the body and the brush constitutes the cutting and extrusion of the green walnuts entering between the blade mounting disc and the brush, thereby completing the task of removing the walnut green peel. The position of the brush and balance adjusting device on the body is adjusted by the gap adjusting device, thus realizing the gap adjustment between the brush and the blade mounting disc to adapt to the processing of green walnuts of various specifications and sizes.

[0008] The object of the present invention can also be achieved as follows: A water spray pipe is provided on the body, through holes are provided on the blade mounting disc, and an impurity outlet is fixed on the frame below the blade mounting disc, thereby constituting a system for spraying and removing debris and impurities during the processing.

[0009] A material blocking device is arranged at the center of the body to prevent green walnuts from entering the area without a brush at the center.

[0010] A material distributing device is also provided on the body for spreading out the green walnuts entering the body.

[0011] The material distributing device is composed of a material distribution mounting plate, a material distribution plate, and a bolt and nut assembly. Two long holes are opened on the material distribution mounting plate and the material distribution plate, and an adjustable-height material distributing device is assembled with the bolt and nut assembly to adapt to green walnuts of different sizes and specifications.

[0012] The U-shaped blades are fixedly installed on the blade mounting disc at an angle of 45 degrees to the diameter line of the blade mounting disc.

[0013] The gap adjusting device includes an adjusting circular ring plate sleeved on the upper part of the machine body. An arc-shaped rack is fixed on the outer wall of the adjusting circular ring plate. A number of guide rail plates are connected to the outer wall of the machine body near the upper and lower end faces of the adjusting circular ring plate to form an orbit on the machine body to restrict the rotation of the adjusting circular ring plate. An adjusting bearing mounting plate is also connected to the outer wall of the machine body near the upper and lower end faces of the adjusting circular ring plate to mount an adjusting shaft. An adjusting gear is fixed on the adjusting shaft, and the adjusting gear meshes with the arc-shaped rack on the outer wall of the adjusting circular ring plate. An adjusting handle and a locking rod are installed at the upper end of the adjusting shaft. A locking tooth plate is connected to the machine body. The locking rod is supported by a spring. When the adjusting handle and the locking rod are held tightly by hand, the handle can be rotated to rotate the adjusting gear to adjust the gap. After releasing the locking rod, the locking rod will be clamped into the tooth notch of the locking tooth plate under the action of the spring support force to lock the adjusting shaft. Two inclined strip holes are opened on the adjusting circular ring plate, and two vertical strip holes are also opened at the corresponding positions on the machine body. The two ends of the lifting shaft connected to the brush mounting frame are inserted into the inclined strip holes of the adjusting circular ring plate and the vertical strip holes on the machine body. When the adjusting circular ring plate rotates along the orbit on the machine body, the lifting shaft rises or falls along the vertical strip holes on the machine body, thereby driving the brush mounting frame and the brush to rise or fall, achieving the adjustment of the gap between the brush and the blade mounting disc below.

[0014] The adjusting circular ring plate is an open circular ring plate. By adjusting the size of the opening, the inner diameter of the circular ring plate is changed, so as to adjust the gap between it and the machine body.

[0015] The brush and balance adjusting device includes two groups of sector-shaped brush mounting frames and brushes. The brush mounting frames are movably mounted on the lifting shafts. A balance adjuster mounting plate is fixed on the machine body. The brush mounting frames are connected to the balance adjuster through adjusting pull rods. The inner sides of the two balance adjusters are connected together through a coupling and a synchronous shaft, and the outer sides are connected to a handwheel through a coupling.

[0016] The balance adjuster adopts a screw jack. By rotating the handwheel, the worm of the screw jack is driven to rotate, driving the turbine to rotate. The push rod and the turbine are in screw engagement. The rotation of the turbine pushes the push rod forward or backward, realizing the push or pull of the adjusting pull rod, thereby driving the brush mounting frame to rotate a certain angle around the lifting shaft and keeping balance.

[0017] The present invention has the following beneficial effects:

[0018] 1) The present invention uses a walnut green peel removal method combining U-shaped blades and brushes. During the peeling process, the U-shaped blades cut, only damaging the walnut green peel, promoting the cracking of the green peel, and then the green peel is removed under the combing and extrusion of the brush. The green peel removal rate is high and the walnut breakage rate is low.

[0019] 2) A fan-shaped peeling channel is formed between the plate brush and the blade mounting disc with U-shaped blades. With this structure, the green walnuts fall from the feeding hopper onto the blade mounting disc. Through the cloth-feeding device, a single layer is laid flat. Then, under the forced rotation of the blade mounting disc, they are brought into the peeling channel. The green peels are removed through the shearing of the U-shaped blades and the mutual extrusion and rubbing with the plate brush. Then, the walnuts with the green peels removed are discharged from the discharge port by the guide plate. The diameter of the blade mounting disc determines the width and stroke of the peeling channel. A wider width and longer stroke result in a higher peeling rate. The width of the channel and the rotation speed of the blade mounting disc determine the production rate. A wider channel width and a higher rotation speed of the blade mounting disc lead to a higher production rate.

[0020] 3) The gap of the fan-shaped peeling channel between the plate brush and the blade mounting disc can be adjusted. By turning the adjusting handle and locking rod of the gap adjusting device, the adjusting gear is controlled to rotate. The arc-shaped rack engaged with the adjusting gear rotates to drive the adjusting ring plate to rotate, driving the lifting shaft to rise or fall, thereby controlling the gap between the plate brush and the blade mounting disc to become larger or smaller to adapt to the peeling of green walnuts of different sizes and specifications. After the gap adjustment is in place, the adjusting gear is locked by releasing the locking rod on the adjusting handle and locking rod and snapping it into the tooth socket of the locking tooth plate.

[0021] 4) The inclination angle between the plate brush and the blade mounting disc can also be adjusted. By rotating the handwheel, the elongation or shortening of the push rod on the balance adjuster is driven, and then the adjusting pull rod is pushed or pulled to control the angle between the plate brush and the blade mounting disc and keep the plate brush balanced. Thus, the green walnuts can smoothly enter between the plate brush and the blade mounting disc to complete the extrusion, rubbing, and cutting operations. At the same time, it can also ensure that the green walnuts with different sizes in the same batch can be smoothly peeled, reducing the breakage rate of the walnuts after peeling.

[0022] 5) By adjusting the height of the cloth-feeding device, the green walnuts of corresponding specifications fall onto the blade mounting disc, laying a single layer flat, preventing the green walnuts from piling up and interfering with each other, and enabling them to enter the fan-shaped peeling channel in sequence, improving the peeling rate and reducing the breakage rate.

[0023] 6) Each group of U-shaped blades on the blade mounting disc is arranged in an inclined parallel manner, and each group is evenly distributed on the blade mounting disc at a certain angle. During the peeling process, the blade mounting disc forcibly brings the green walnuts into the peeling channel. Under the mutual extrusion, shearing, and friction of the plate brush and the blades, the blades make multiple cracks on the green peels of the walnuts, laying a foundation for the plate brush to easily brush off the green peels of the walnuts, so the peeling rate is high.

[0024] 7) Two groups of fan-shaped peeling channels are designed between the two groups of plate brushes and the blade mounting disc, increasing the peeling stroke. The gaps between the two groups of plate brushes and the blade mounting disc are synchronously increased and decreased under the adjustment of the two groups of balance adjusters, further improving the peeling rate and reducing the breakage rate of the walnuts.

[0025] 8) During the peeling process, a water spray pipe is arranged at the lower opening of the feed hopper for spraying. This can not only play a lubricating role during the peeling process to reduce the breakage rate, but also timely clean impurities such as green peel residues on the U-shaped blades and the blade mounting disc, preventing the adhesion of impurities such as green peel on the U-shaped blades and the blade mounting disc. Through the long round holes on the blade mounting disc, the green peel residues and other impurities are discharged through the impurity outlet.

[0026] 9) The present invention can be continuously produced with high productivity, suitable for large-scale processing, and realizes the processing and transformation of walnuts in the planting production areas.

[0027] 10) The mechanical structure of the present invention is compact, easy to adjust, with a high shelling rate and a low breakage rate, greatly reducing the processing cost of green walnuts.

[0028] 11) The present invention reduces the labor intensity of operators, improves the sanitary conditions, and enhances the commercial appearance quality and internal quality of walnuts. Description of the Drawings

Specific Embodiment 1:

[0054] The frame 7 is installed with a transmission shaft bearing mounting plate 21. The bearing is fixed on the transmission shaft bearing mounting plate, the transmission shaft 20 is fixed on the bearing. A reducer fixing device 22 is arranged below the frame to fix the motor reducer 6. The power is transmitted to the flange 15 through the transmission shaft. The flange 15 is connected to the blade mounting disc 33. The U-shaped blades 34 are installed on the blade mounting disc 33. A group of U-shaped blades are arranged in an inclined parallel manner in the direction of the disc diameter line, forming an overall circular turntable with a number of U-shaped blades and long strip holes installed. Above the blade mounting disc 33, a feed hopper 1 is provided. A water spray pipe 28 and a cloth distributing plate 32 are arranged at the feed hopper. The cloth distributing plate 32 is installed on the cloth mounting plate 31. The water spray pipe is installed on the material blocking device 17 and the guide plate 30. A guide plate 30 is arranged beside the feed hopper. A discharge port 4 is arranged on the machine body 3 corresponding to the guide plate. The outer ends of the guide plate 30 and the cloth mounting plate 31 are connected to the machine body 3, and the inner ends are welded to the material blocking device 17. Above the blade mounting disc 33, a plate brush 19 is provided. The plate brush is installed on the plate brush mounting frame 18. The plate brush mounting frame 18 is connected to the machine body 3 and the adjusting ring plate 2 through a lifting shaft 29. An adjusting ring plate 2 is arranged outside the machine body 3. The adjusting ring plate 2 can rotate around the central axis of the machine body along the track formed by the guide rail plate piece 35. An arc-shaped rack 10 is arranged on the adjusting ring plate 2. The adjusting gear 12 meshes with the arc-shaped rack 10. The adjusting gear is fixed on the adjusting shaft 11. The adjusting shaft 11 is fixed on the adjusting bearing 9. The adjusting bearing 9 is fixed on the adjusting bearing mounting plate 8. The adjusting bearing mounting plate 8 is welded to the machine body 2. An adjusting handle and a locking rod 14 are installed at the upper end of the adjusting shaft 11. A locking tooth plate 13 is welded on the machine body 2. By rotating the adjusting handle and the locking rod 14, the adjusting shaft 11 is driven to rotate, thereby driving the adjusting gear 12 to rotate, driving the adjusting ring plate 2 to rotate, and thus driving the lifting shaft 29 to rise and fall along the inclined long strip holes on the adjusting ring plate 2 and the vertical strip holes of the machine body 2, so as to adjust the gap between the plate brush 19 and the blade mounting disc 33.

[0055] Two groups of plate brush mounting frames 18 are symmetrically distributed and are respectively connected to the balance adjuster 25 through adjusting pull rods 26. The inner sides of the two groups of balance adjusters 25 are connected together through a coupling 24 and a synchronous shaft 27, and the outer sides are connected to the hand wheel 23 through a coupling 24. By rotating the hand wheel to drive the movement of the balance adjuster, pulling the adjusting pull rod 26 forward and backward, the plate brush mounting frame 18 and the plate brush 19 are synchronously rotated around the lifting shaft 29, so as to realize the angle adjustment and balance between the plate brush 19 and the blade mounting disc 33. The balance adjuster 25 is installed on the balance adjuster mounting frame 16. The balance adjuster mounting frame 16 is connected to the inner side of the machine body 2 through bolts. Below the blade mounting disc 33, an impurity outlet 5 is provided. The impurity outlet is fixedly connected to the frame. The green walnut crushed residue impurities and water falling from the strip holes on the blade mounting disc 33 are discharged from the impurity outlet 5.

[0056] The specific implementation plan is as follows: After turning on the power, check whether the rotation direction of the motor reducer 6 is correct. Processing can be carried out only after the machine runs normally. The green walnuts fall into the surface of the turntable equipped with several U-shaped blades 34 and the blade mounting disc 33 with several long strip through holes through the feed hopper 1. The motor reducer 6 transmits power to the flange 15 through the transmission shaft 20, and the flange drives the blade mounting disc to rotate, and the green walnuts rotate accordingly; under the action of the cloth plate 32, the falling green walnuts spread out in a layer on the blade mounting disc and move forward, entering the fan-shaped peeling channel area formed between the plate brush 19 and the blade mounting disc 33, and the U-shaped blades and the plate brush 19 are in direct contact with the green walnuts; the plate brush is fixed, and the blade mounting disc equipped with U-shaped blades carries the green walnuts and rotates forward, forming a relative movement between the two. The peeling of the walnuts is completed under the cutting, rubbing and extrusion of the U-shaped blades and the plate brush. By rotating the adjusting handle and the locking rod 14, the gap between the plate brush 19 and the blade mounting disc 33 can be adjusted to adapt to the peeling of green walnuts of different shapes and sizes. By turning the handwheel 23, the inclination angle between the plate brush 19 and the blade mounting disc 33 can be adjusted to form a squeezing process with a gradually decreasing gap, so as to adapt to the peeling of green walnuts of different specifications, varieties and different peeling degrees in the same batch. During the forward extrusion process of the green walnuts, multiple cracks are scratched by the U-shaped blades, and are continuously combed by the plate brush. At the same time, they are subjected to the water spraying, lubricating and cleaning action of the water spray pipe 28. The green walnut peel continuously falls off and becomes smaller. At the same time, the extrusion gap also continuously becomes smaller, adapting to the size change from green walnuts to walnuts, and completely removing the green peel on the surface of the walnuts. The walnuts without green peel are discharged from the discharge port 4 through the guide plate 30 and enter the next walnut and green peel separation device. The impurities such as green peel residues and water leak out from the long strip holes on the blade mounting disc and fall into the impurity outlet 5 and are discharged.

[0057] The working process of the present invention is as follows: The motor reducer transmits power to the flange through the transmission shaft. The flange drives the blade mounting disc to rotate. A number of U-shaped blades are installed on the blade mounting disc, forming a conveying disc formed by U-shaped blades and long strip holes. The green walnuts fall onto the surface of the blade mounting disc and enter the first group of peeling channels as the disc rotates; under the action of the cloth-feeding device arranged at the feed hopper, the green walnuts spread out in a layer on the surface of the blade mounting disc and move forward, entering the first group of fan-shaped peeling channel areas formed between the brush and the blade mounting disc. A water spray pipe is arranged above the blade mounting disc at the feed hopper. While the green walnuts are rotating on the blade mounting disc, they are lubricated by the sprayed water. During the continuous extrusion and shearing peeling process of the green walnuts, the U-shaped blades cut out multiple cracks on the walnut green peel, and then enter the second group of peeling channels through the first group of peeling channels. Under the extrusion and scraping action of the brush, the green peel is removed, and a guide plate is arranged at the outlet of the second group of peeling channels. Under the action of the guide plate, the peeled walnuts are conveyed to the discharge port. In the working or maintenance state, the gap between the brush and the blade mounting disc is adjusted and controlled through the gap adjusting device to adapt to the peeling of green walnuts of different sizes; the inclination angle between the brush and the blade mounting disc can also be synchronously controlled by the handwheel and kept balanced, so as to realize the squeezing process of green walnuts from large to small. During the peeling process, the walnut green peel continuously falls off and becomes smaller, and at the same time the extrusion gap also continuously becomes smaller. Under the action of the two groups of peeling channels, it adapts to the size change from green walnuts to walnuts. The green walnuts are continuously brushed by the brush during the forward movement, and then are output to the discharge port through the guide plate and enter the green peel and walnut sorting device of the next process. The green peel scraps, impurities and water fall into the impurity outlet through the gaps of the strip holes on the blade mounting disc for exclusion and collection.

When the adjusting ring plate rotates along the track on the body, the lifting shaft rises or falls along the vertical strip holes on the body, thereby driving the brush plate mounting frame and the brush plate to rise or fall, achieving the adjustment of the gap between the brush plate and the blade mounting disc below. The described brush plate and balance adjustment device includes two groups of sector-shaped brush plate mounting frames and brush plates. The brush plate mounting frames are movably installed on the lifting shaft. A balance adjuster mounting plate is fixed on the body. The brush plate mounting frame is connected to the balance adjuster through an adjusting pull rod. The inner sides of the two balance adjusters are connected together through a coupling and a synchronous shaft, and the outer sides are connected to a handwheel through a coupling. The balance adjuster adopts a screw lift. By rotating the handwheel, the worm of the screw lift is driven to rotate, driving the turbine to rotate. The push rod is in screw engagement with the turbine. The rotation of the turbine pushes the push rod forward or backward, realizing the push or pull of the adjusting pull rod, thereby driving the brush plate mounting frame to rotate a certain angle around the lifting shaft and maintaining balance.
