Description

Green walnut peeling machine

technical field

The invention relates to a green walnut peeling machine, in particular to a machine for peeling green walnut peels, which belongs to the technical field of agricultural machinery.

Background technique

During the walnut harvest period, a large number of mature green walnuts are in urgent need of peeling. Traditionally, the method of natural decay and peeling of green skins in the pool and manual peeling is used. These methods not only have low work efficiency, high labor intensity, great damage to hands and skin, but also walnuts are easily contaminated by fungi. At present, mechanical peeling equipment has been adopted in a few areas in China. Green walnut peeling equipment that has been researched and developed in China includes: (1) Patent No. 02206407.9, 6BXH-800 walnut green peel peeling and cleaning machine. This peeling device has the problem of large water consumption; (2) Patent No. 200720105163.1, 200720112411.5 And 200520012972.9 walnut peeling machine. The main working parts of these three machines are composed of rotating hard rubber rollers and grid bars concentrically set outside the rollers, and use the principle of extrusion and rubbing to peel off the green skin. Due to the large difference in the shape and size of walnuts, and the relative positions of the rubber rollers and grid bars of the above-mentioned machines cannot be adjusted or are difficult to adjust, problems such as poor peeling effect, high breakage rate and complicated installation and adjustment will occur during peeling off. The device needs to grade green walnuts in advance; (3) the walnut peeling machine whose patent number is 03244924.0. The working parts of the machine are composed of a conveyor belt, a pressing iron plate and a cutter. When the motor drives the conveyor belt to move, walnuts are forced to pass through the cutter under the extrusion of the conveyor belt and the pressing iron plate to remove the green skin. The shortcoming of this implement is that the bigger green walnuts of size can't enter the working area, for the lesser walnuts of size, because the extruding force is too little and difficult to take off the green skin; (4) the green walnut peeling machine that the patent No. is 200820130420.1. The machine utilizes the peeling knife to cut and remove the green bark by the extrusion of the rotating drum and the peeling concave plate. The disadvantage of this machine is that the peeling knife is easy to cause the walnuts to break.

Due to the variety of walnut varieties in our country, the size difference is large, the shape is irregular, and the thickness and strength of the walnut shell are also quite different. Most of the walnut shapes are non-spherical. Clean rate and broken rate.

Detailed ways

With reference to above-mentioned accompanying drawing, specific embodiment of the present invention is described in detail, green walnut peeling machine as shown in Figure 1 is made up of feeding hopper, power unit, transmission part, working part, frame, green peel hopper and walnut hopper. A feeding hopper 10 is arranged above the frame 2, and a control valve plate 11 is installed on one side of the feeding hopper to control the amount of material feeding; the partition 21 is an arc plate of 90-220 degrees, divided into 3-10 groups along the axis of the peeling cylinder 13 Arranged concentrically with the peeling drum, the peeling concave plate 6, the separator 21 and the peeling drum 13 form 3 to 10 channels; the distance between the peeling concave plate 6 and the peeling drum 13 can be adjusted by the adjustment mechanism 22; the peeling drum 13 is composed of a belt seat The bearing is supported on the frame 2, the outer surface of the peeling cylinder is fixedly connected with a patterned wear-resistant rubber plate 12, and the cylinder shaft 15 is driven by the motor 1 through a belt transmission; the torsion spring fixing rod 8 and the concave plate support rod 9 are fixed on the On the support plate 5, the support plate 5 is fixed on the frame 2; the support plate 5 is an arc plate of 90 to 220 degrees, and 3 to 8 concave plate support rods 9 are fixed on the circumference of the arc plate from top to bottom. The peeling gravure 6 is hinged on the plate support rod, and the gap between the peeling gravure and the peeling cylinder 13 gradually decreases; the peeling gravure 6 is pressed with a torsion spring 7, and the pressure of the torsion spring on the peeling gravure 6 is adjusted to adapt to different varieties and The walnut green skins of different sizes are peeled off; the auger 4 is located at the outlet of the peeling channel, and the grid separation plate 3 is installed below the auger 4 to separate the walnuts from the green skins.

Working process and principle of the present invention are as follows:

When the green walnut peeling machine is working, the motor 1 drives the drum shaft 15 to rotate through the belt 17. The drum shaft 15 is connected with the peeling drum 13. The green walnuts in the feeding hopper 10 enter the peeling channel from the feeding hopper outlet for peeling. The peeling channel is formed by the peeling concave plate. 6, dividing plate 21 is formed with peeling cylinder 13, and the spacing between adjacent dividing plates has limited every passage once and can only enter a green walnut. When the peeling cylinder 13 rotates, the green walnuts entering the peeling passage move along the tangential direction and contact the peeling concave plate 6 under the drive of the peeling cylinder 13. Because the green walnut size is greater than the gap between the peeling cylinder and the peeling concave plate, the green walnut The peeling concave plate 6 is jacked up during motion, and the torsion spring 7 pressed on the peeling concave plate prevents the peeling concave plate from turning upwards. Under the joint action of peeling concave plate 6 and peeling cylinder 13, walnut green skin is peeled off. The spacing between the peeling concave plate 6 and the peeling cylinder 13 can be adjusted by an adjustment mechanism 22, so as to adapt to walnuts of different external dimensions. Peeled walnuts and green peels are discharged from the peeling concave plate 6, and enter the auger 4, and the grid separation plate 3 is installed directly below the auger, which is used for separating walnuts and green peels. When the auger rotates, the walnuts are pushed out of the machine tool, and the green skins are extruded from the gap of the grid bar separation plate, and discharged through the green skin discharge hopper 18. The preload size of torsion spring 7 that is pressed on the peeling concave plate 6 is adjustable, and is used for peeling off green walnut skins of different varieties and different sizes.

Finally, it should also be noted that what is listed above is only a specific embodiment of the present invention. Apparently, the present invention is not limited to the above embodiments, and many variations are possible, and all variations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention are considered to be within the protection scope of the present invention.
