At present, a common straw roller press consists of a pair of press rollers and a rotating motor connected with the press rollers. Through the drive of rotating the motor, two compression rollers rotate in opposite directions, and corn stalk passes through gradually from the gap between two compression rollers, is rolled by the compression roller for the higher structure of the inside hardness of straw is destroyed, thereby lets the straw of roll extrusion more easily smashed by rubbing crusher. During the rolling process, partial juice is separated from the straws, and the juice contains more mineral elements such as potassium, phosphorus and the like. These mineral elements also have the effect of promoting the production of crops, so that these juices can also be made into organic fertilizers after collection. However, the existing straw roller presses cannot collect the juice, so that the waste of organic fertilizer raw materials is caused.

Disclosure of Invention

The invention aims to provide a straw roller press which can collect juice separated out in the straw rolling process, so that the purpose of fully utilizing organic fertilizer raw materials is achieved, and the problem of waste of the organic fertilizer raw materials is solved.

In order to achieve the purpose, the invention provides a straw roller press, which comprises a pair of press rollers, wherein one end of each press roller is connected with a rotating motor, the press rollers are cylindrical and obliquely arranged, a first pressure valve is arranged at an opening at the lower end of each press roller, the side wall of each press roller is provided with a plurality of conveying pipes and a plurality of first grooves with openings facing the outside of the press roller, the first grooves are positioned at the upper parts of the side walls of the press rollers and communicated with the conveying pipes, the conveying pipes are arranged along the axial direction of the press rollers, the pipe diameter of the lower ends of the conveying pipes is larger than that of the upper ends of the conveying pipes, the lower ends of the conveying pipes are also communicated with the inside; the inner wall of the squeezing roller is provided with a piston plate and a strip-shaped convex block, the convex block is fixedly connected with the squeezing roller, the side wall of the piston plate is provided with a second groove in sliding fit with the convex block, the inner wall of the second groove is abutted against the side wall of the convex block, and the side wall of the piston plate is also abutted against and in sliding connection with the inner wall of the squeezing roller; still be equipped with reset spring between piston plate and the press roll, reset spring's one end and piston plate fixed connection, reset spring's the other end and the inner wall fixed connection who squeezes the roller, the one end that the piston plate is up is equipped with one end and its fixed connection's bracing piece, the other end of bracing piece is located and squeezes the roller outer and fixedly connected with cylindrical cam, squeezes the roller outer still be equipped with cylindrical cam complex gag lever post, gag lever post and the shell fixed connection who rotates the motor.

The technical principle and the technical effect of the technical scheme are as follows: the technical scheme provides a straw roller press which realizes the rolling of straws by arranging a pair of pressing rollers driven by a rotating motor. A first pressure valve is arranged at the lower end of the press roll and can only be opened when the air pressure inside the press roll increases. The juice separated out in the straw rolling process is attached to the surface of the press roll, and along with the rotation of the press roll, a large part of juice can enter the first grooves formed in the side wall of the press roll. Since the first groove communicates with the conveying pipe and the press roll is disposed obliquely, the juice can flow into the conveying pipe and move to the lower end of the conveying pipe. A second pressure valve is also arranged at the lower end of the transport pipe and can be opened only when the air pressure inside the press roll is reduced.

Because the side wall of the piston plate is provided with the second groove matched with the convex block, and the convex block is fixedly connected with the inner wall of the squeezing roller, the piston plate can not rotate relative to the squeezing roller, but can synchronously rotate along with the squeezing roller, and can also slide along the convex block. In the process of rotation of the piston plate, the cylindrical cam connected with the piston plate through the support rod synchronously rotates and slides back and forth along the convex block under the action of the fixed limiting rod and the return spring. When the piston plate slides upwards inside the press roll, the air pressure between the first pressure valve and the piston plate is reduced, so that the second pressure valve is opened, and the first pressure valve is closed, thereby sucking the juice in the conveying pipe into the press roll; when the piston plate slides downwards, the air pressure between the first pressure valve and the piston plate is increased, so that the second pressure valve is closed, the first pressure valve is opened, and the juice in the squeezing roller is squeezed out and sent into the juice collecting device. If the piston plate is not provided, it is necessary to wait for the juice to slowly slide along the inside of the feed pipe or the press roll, and since the juice has a certain viscosity, the sliding speed is slower. Therefore, by providing the piston plate, the rate at which juice moves can be increased, thereby improving the production efficiency.

In conclusion, according to the technical scheme, the first grooves and the conveying pipe are arranged on the side wall of the press roll, so that the juice attached to the surface of the press roll can be gathered inside the press roll, and the collection of the straw juice is completed. In addition, the piston plate connected with the cam is arranged in the squeezing roller, so that the change of the internal air pressure can be realized, the moving speed of the juice is increased, and the production efficiency is improved.

The following are preferred embodiments of the above scheme:

the first preferred scheme is as follows: based on the basic scheme, an opening at the upper end of the squeezing roller is detachably connected with an end cover, and a first through hole matched with the supporting rod is formed in the end cover; the upper end of the conveying pipe is provided with a second through hole communicated with the inside of the squeezing roller, the joint of the second through hole and the inner wall of the squeezing roller is positioned between the piston plate and the end cover, and a third pressure valve is arranged at the second through hole and can be opened only when the pressure inside the squeezing roller is increased.

By providing the end caps, an approximately closed space is formed between the upper end of the press roll and the piston plate. When the piston plate moves upwards, the air pressure between the piston plate and the end cover is increased, so that the third pressure valve is opened, and the air inside the press roll overflows from the second through hole and enters the conveying pipe. Because the atmospheric pressure between piston plate and the first pressure valve reduces this moment for the gas in the conveyer pipe flows to squeezing the roller inside fast, thereby lets the air that overflows in the second through-hole remove to the conveyer pipe lower extreme, will adhere to the juice area of pipe wall and remove together simultaneously, and then increases the speed of the removal of juice in the conveyer pipe, improves production efficiency.

The preferred scheme II is as follows: based on the first preferred scheme, sealing rings are arranged at the joint of the end cover and the press roll and the joint of the end cover and the support column, and water is injected between the end cover and the piston plate in the press roll. When the piston plate moves upwards, the water pressure between the piston plate and the end cover is increased, so that the third pressure valve is opened, and the water inside the press roll overflows from the second through hole and enters the conveying pipe. When water moved in the conveyer pipe, can erode the pipe wall, flow the juice area fast to the conveyer pipe lower extreme, further improve the transport speed of juice, improve production efficiency.

The preferable scheme is three: based on the basic scheme, the width of the opening of the first groove is 3-6 mm. When the width of first recess opening part was less than 3mm, first recess was blocked by the straw piece easily, causes the unable condition that gets into first recess of juice. When the width is larger than 6mm, the juice entering the first groove is easily thrown out under the action of centrifugal force generated by the rotation of the squeezing roller, so that the juice is wasted.

The preferable scheme is four: based on preferred scheme three, first recess encircles the outer wall setting of squeezing the roller for a first recess can with all conveyer pipes intercommunication, let the juice in the first recess can get into the conveyer pipe as early as possible, avoid the juice to be thrown away first recess, cause the waste.

The preferable scheme is five: based on the fourth preferred scheme, the outer wall of the press roll is slidably connected with a pair of positioning plates vertical to the press roll, one positioning plate is positioned between the first groove and the upper end of the side wall of the press roll, and the other positioning plate is positioned between the first groove and the lower end of the side wall of the press roll. Through setting up the locating plate, can guarantee that the straw can not slide downwards at the in-process of roll extrusion, cause the straw to break away from the condition of roller.
