Description

Technical Field

[0001] The invention relates to the technical field of walnut pretreatment equipment, and more specifically, particularly to a walnut sawing pretreatment machine. Background Art

[0002] Walnut is an important oil crop. In recent years, the walnut industry has developed steadily and the market demand has continued to increase. In order to maximize the economic benefits of walnut products, walnuts need to be processed. Walnut shelling and kernel extraction are the key links in the primary processing of walnuts. The kernel extraction effect will directly affect the quality of subsequent deep processing of walnuts.

[0003] Some deep-grained walnut varieties, such as Yunnan Yangbi walnut (Juglans sigillata Dode), have the characteristics of small distance between shell and kernel and close connection of the heartwood in the navel. When directly put into the shelling machine for shelling, the walnut kernel is easily damaged, resulting in a high kernel exposure rate and low kernel exposure rate. In view of the above problems, before the walnut shell is cracked and the kernel is taken out, an end cutting pretreatment process is added to destroy the spherical shell structure of the walnut and change its stress characteristics. At the same time, the cutting pretreatment at the appropriate position can destroy the heartwood structure inside the walnut, avoiding the situation that the walnut kernel is stuck in the unbroken heartwood during the subsequent shelling and kernel removal, resulting in the need for secondary shelling, thereby improving the high kernel exposure rate of this type of walnut shelling and kernel removal and reducing the broken kernel rate.

[0004] Most of the existing mechanical walnut pre-processing machines use the notching method to process walnuts. This method cannot effectively destroy the compact wood structure of the deep-grained walnut varieties in Yunnan. In addition, the existing walnut pre-processing machines have problems such as low cutting efficiency, poor adaptability to walnuts of different sizes, and loose fixation of walnuts during notching. These problems result in the existing machines being unable to meet the requirements of high-efficiency and high-quality pre-processing of Yunnan walnuts. Summary of the invention

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention aims at the characteristics of Yunnan deep-grained walnut varieties, such as small shell-kernel spacing and tight core wood, and proposes a sawing preprocessing machine for the end of the walnut, i.e., the navel / tip of the walnut. The walnuts can be transported in an orderly manner through a feeding device, the walnut position can be adjusted and the walnut edges can be aligned through a transport adjustment device, the walnuts can be pressed by a pressing device when they are sawed, and the end of the walnut can be sawed by a sawing device;

[0027] Compared with incision pretreatment, sawing the ends of walnuts can destroy the spherical shell structure of the walnuts to a greater extent, change its stress characteristics, and make the walnuts easier to crack in subsequent processing, thereby improving the high kernel rate; in addition, a small amount of sawing on the ends of deep-grained walnuts can effectively destroy the solid center wood structure there, reducing the situation where walnuts get stuck in the center wood when cracking the shells and taking out the kernels, and requiring secondary shelling, so that the subsequent shelling effect is further improved.

[0028] (2) The present invention can adjust the position of walnuts during the feeding and conveying process, and the position adjustment is applicable to walnuts of different sizes and shapes, so that the fed walnuts are arranged in a straight line in the same axial direction and fall into the conveying adjustment device in an orderly manner. The structure is simple and the reliability of walnut conveying is ensured.

[0029] (3) In the conveying and adjusting device of the present invention, the walnut bases and base rollers are alternately arranged, and the walnuts conveyed by the feeding device will fall into the walnut base under the action of the base rollers and keep the axial direction the same as the direction of the base rollers; in addition, the conveying and adjusting device is installed at a certain angle to the plumb plane, and the walnuts on the walnut base can slide down under the action of gravity until the end of the walnut contacts the side flush baffle, thereby walnuts of different shapes and sizes can be processed to be flush with the edges. In the subsequent sawing process, the sawing of the ends of walnuts of different sizes can use the flush baffle as a reference to obtain the same sawing depth, and the structure is simple and the function is reliable.

[0030] (4) The present invention achieves the clamping and sawing of walnuts at the desired position while ensuring the continuous operation of the walnut conveyor belt. The clamping device is connected to the walnut conveying adjustment device through a chain drive, ensuring a certain transmission ratio. This transmission ratio allows the hexagonal support frame to rotate 60° and the walnut conveyor chain below to deliver a walnut. At this time, the walnut is engaged and clamped by the flexible clamping belt on the hexagonal support frame, thereby achieving a clamping method that simulates the meshing of gears and racks. When the walnut is pressed to the tightest by the flexible clamping belt on the hexagonal clamping device, the end of the walnut is sawed by the sawing device to prevent the walnut's posture from being changed by the sawing force, thereby ensuring the reliability of the overall operation of the mechanism.

[0073] The frame 51 includes a support base 511 and a support slot 512 disposed on the support base 511. The end of the support slot 512 is provided with a discharge port 54.

[0074] The shell 52 is an inverted U-shaped structure, which is mounted on both sides of the support trough 512 and covers the working part of the peach navel / tip sawing preprocessing machine. The conveying adjustment device 20 is arranged on the support trough 512, and the pressing device 30 is arranged in the shell 52 and located above the support trough 512; the sawing device 40 is arranged in the shell 52 and located on one side of the support trough 512.

[0077] The walnut sawing pretreatment machine provided by the present invention has the following specific working principle:

[0078] When the machine is working, the walnuts to be processed are put into the feeding hopper 102 on the feeding device 10, and the feeding trough 103 of the feeding device 10 feeds the walnuts into the conveying and adjusting device 20 in the same axial direction and in an orderly manner.

[0079] As attached Figure 7 As shown, after the walnuts to be processed fall into the conveying and adjusting device 20 at the arrow ① position, the axis directions of all the walnuts can be kept parallel under the action of the base roller 25. Since the conveying and adjusting device 20 is tilted, all the walnuts will slide down along the arrow G direction under the action of gravity until the end of the walnut contacts the flush baffle 23, so that the posture of the walnuts of different sizes on the double-ear chain 29 is consistent, that is, the axis directions of all the walnuts are consistent, and the ends are flush.

[0080] On the basis of the above-mentioned posture adjustment, the double-ear chain 29 of the conveying and adjusting device 20 moves in the direction of arrow V to continue to transport the walnut forward. When the walnut reaches the arrow ② position, the end of the walnut in contact with the flush baffle 23 is about to contact the saw blade 41. At this time, the flexible pressing belt 34 of the pressing device 30 presses the walnut to prevent the walnut from deviating due to the sawing force; at the same time, the DC motor 45 of the sawing device 40 drives the handle 42 and the saw blade 41 to work, and the saw blade 41 is used to saw the end of the walnut, and the sawed part passes along the waste guide groove 231 on the inclined flush baffle 23 and is discharged from the waste discharge chute 46.

[0081] As attached Figure 8As shown, when the flexible pressing belt 34 of the pressing device 30 presses the walnuts, under the action of the transmission chain 38, when the double-ear chain 29 of the conveying and adjusting device 20 moves in the direction of the arrow V, the hexagonal support frame 33 of the pressing device 30 rotates in the direction of the arrow ω. In addition, the transmission ratio provided by the transmission chain 38 can make the hexagonal support frame 33 of the pressing device 30 rotate 60°, and under the action of the sleeve 311, the corresponding walnut is pushed forward, that is, the lower walnut conveying double-ear chain 29 transmits a walnut. At this time, the walnut is engaged and pressed by the flexible pressing belt 34 on the hexagonal support frame 33, and a kind of imitation gear rack meshing type pressing is also realized, which ensures that the walnuts are reliably pressed and reliably sawed.

[0082] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
