Description

Technical Field

[0001] This utility model relates to a crushing device, specifically an agricultural straw crushing device, belonging to the technical field of straw crushers. Background Technology

[0002] The main function and purpose of a straw crusher is to crush agricultural waste such as straw into small particles for further processing or direct use. This equipment is widely used in agriculture, forestry, animal husbandry and other fields. Through crushing, straw can be converted into valuable products such as biomass energy, organic fertilizer or feed, realizing the recycling of resources.

[0003] However, when existing crushers are used on the ground, the straw fragments sprayed onto the ground by the crusher form a thick layer of straw. This straw layer may hinder the germination and emergence of crops. Furthermore, the straw piles on the ground need to be cleaned up. The crusher is not easy to move, which reduces its utilization rate. Utility Model Content

[0004] The purpose of this utility model is to provide an agricultural straw crushing device to solve the above problems. The limiting frame is hung on a tricycle, and the rotating block is rotated to make the sleeve rod drive the sliding rod and the abutment plate to move, so that the abutment plate abuts against the rear of the tricycle, thereby making the crusher body in a stable state when crushing the straw.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an agricultural straw crushing device, comprising a crusher body, a base, a baffle, and a feed hopper fixedly installed on the crusher body, a protective mechanism engaged on the feed hopper, two fixing mechanisms symmetrically installed on the crusher body about the baffle, each fixing mechanism including a limiting frame and a support block, a support block fixedly connected to the crusher body, a slot provided on the support block, a limiting frame engaged on the support block, a rubber pad adhered to the limiting frame, a sleeve rod rotatably connected to the limiting frame, a rotating block fixedly installed on the sleeve rod, a sliding rod threadedly connected to the sleeve rod, and a stop plate fixedly connected to the sliding rod.

[0006] Preferably, the two support blocks are symmetrically arranged about the baffle, and the slot portion engages with and is fitted with a limit frame.

[0007] Preferably, the diameter of the sleeve rod is larger than the diameter of the slide rod, and the abutment plate and the limiting frame are slidably connected.

[0008] Preferably, the two limiting frames are located at the end of the crusher body away from the feed hopper, and the rubber pad is located on the side wall of the limiting frame near the abutment plate.

[0009] Preferably, the width of the rotating block is greater than the diameter of the sleeve rod, and the rotating block is arranged in a cross shape.

[0010] Preferably, the baffle is arranged with an arc surface structure, and the baffle is in communication with the interior of the crusher body.

[0011] Preferably, the feed hopper is connected to the side of the crusher body away from the baffle, and the feed hopper is arranged with an inclined structure.

[0012] Preferably, the protective mechanism includes a retaining frame and limiting rods. The retaining frame is engaged with the feed hopper, and several limiting rods are threaded onto the retaining frame. The limiting rods penetrate the inner wall of the retaining plate, and several baffles are fixedly installed at equal intervals on the retaining plate.

[0013] Preferably, the card frame is located at the top of the feed hopper, and the bottom end of the card plate is in contact with the card frame.

[0014] Preferably, the limiting rod contacts the top of the card plate, and the plurality of the curtains are arranged at equal intervals.

[0015] The beneficial effects of this utility model are as follows: Before crushing the straw, the operator can first hang the limiting frame installed inside the support block on the rear side wall of the electric tricycle. The limiting frame supports the weight of the crusher body. Then, the operator can rotate the rotating block by hand. Since a sleeve rod is fixedly installed on the rotating block, when it drives the sleeve rod to rotate along the inner wall of the limiting frame, the sliding rod connected to the thread on the sleeve rod can drive the fixed abutment plate to move. Since the top of the abutment plate is slidably connected to the limiting frame, the abutment plate is limited by the limiting frame and can only slide along the inner wall of the limiting frame. When the abutment plate slides to the state of contacting the rear side wall of the tricycle, the rubber pad on the limiting frame can contact the rear side wall. The setting of the rubber pad also makes it easier to increase the friction between the limiting frame and the rear side wall, which helps to prevent the crusher body from being in an unstable state when crushing straw.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 As shown, an agricultural straw crushing device includes a crusher body 1. A base 2, a baffle 3, and a feed hopper 4 are fixedly installed on the crusher body 1. A protective mechanism 5 is engaged on the feed hopper 4. Two fixing mechanisms 6 are symmetrically installed on the crusher body 1 about the baffle 3. Each fixing mechanism 6 includes a limiting frame 605 and a support block 607. The support block 607 is fixedly connected to the crusher body 1. The support block 607 has a slot 608. The limiting frame 605 is engaged on the support block 607. A rubber pad 606 is adhered to the limiting frame 605. A sleeve rod 602 is rotatably connected to the limiting frame 605. A rotating block 601 is fixedly installed on the sleeve rod 602. A sliding rod 603 is threadedly connected to the sleeve rod 602. A stop plate 604 is fixedly connected to the sliding rod 603.

[0026] As a technical optimization of this utility model, the two support blocks 607 are symmetrically arranged about the baffle 3, and the slot 608 is engaged with the limiting frame 605. When the limiting frame 605 contacts the rear of the tricycle, the weight of the crusher body 1 can be supported by the limiting frame 605.

[0027] As a technical optimization of this utility model, the diameter of the sleeve rod 602 is larger than the diameter of the slide rod 603, the abutment plate 604 is slidably connected to the limiting frame 605, and the rotating block 601 drives the sleeve rod 602 to rotate, which can cause the slide rod 603 to move the abutment plate 604.

[0028] As a technical optimization of this utility model, the two limiting frames 605 are located at the end of the crusher body 1 away from the feed hopper 4, and the rubber pad 606 is located on the side wall of the limiting frame 605 near the abutment plate 604. When the rubber pad 606 contacts the rear side wall of the tricycle, it can increase the friction between the limiting frame 605 and the rear side wall.

[0029] As a technical optimization of this utility model, the width of the rotating block 601 is greater than the diameter of the sleeve rod 602, and the rotating block 601 is arranged in a "+" shape. The rotating block 601 makes it easier for the operator to rotate the sleeve rod 602.

[0030] As a technical optimization of this utility model, the baffle 3 is arranged in an arc-shaped structure and is connected to the interior of the crusher body 1. After the crusher body 1 crushes the straw, the crushed material can be discharged from the inside of the equipment through the baffle 3.

[0031] As a technical optimization of this utility model, the feeding hopper 4 is connected to the side of the crusher body 1 away from the baffle 3, and the feeding hopper 4 is set with an inclined structure. The straw is pushed into the feeding hopper 4 and transported to the crushing component along the inner wall of the feeding hopper 4.

[0032] As a technical optimization of this utility model, the protective mechanism 5 includes a frame 501 and a limiting rod 503. The frame 501 is snapped onto the feed hopper 4, and a plurality of limiting rods 503 are threaded onto the frame 501. The limiting rods 503 penetrate the inner wall of the plate 502. A plurality of curtains 504 are fixedly installed at equal intervals on the plate 502. The curtains 504 can be installed by snapping the frame 501 onto the feed hopper 4.

[0033] As a technical optimization of this utility model, the card frame 501 is located at the top of the feed hopper 4, and the bottom end of the card plate 502 is in contact with the card frame 501. When the through hole provided on the card plate 502 is aligned with the through hole provided on the card frame 501, the card plate 502 can be limited.

[0034] As a technical optimization of this utility model, the limiting rod 503 contacts the top of the card plate 502, and several of the curtains 504 are arranged at equal intervals. When the limiting rod 503 is threaded into the card frame 501, the card plate 502 can be fixed to the top of the card frame 501.

[0035] In use, before crushing the straw, the operator can first hang the limiting frame 605 installed inside the support block 607 on the rear side wall of the electric tricycle. The limiting frame 605 supports the weight of the crusher body 1. Then, the operator can manually rotate the rotating block 601. Since the rotating block 601 is fixedly installed with the sleeve rod 602, when it drives the sleeve rod 602 to rotate along the inner wall of the limiting frame 605, the sliding rod 603 threaded on the sleeve rod 602 can drive the fixed abutment plate 604 to move. Since the top of the abutment plate 604 is slidably connected to the limiting frame 605, the abutment plate 604 is limited by the limiting frame 605 and can only slide along the inner wall of the limiting frame 605. When the abutment plate 604 slides to the state of contacting the rear side wall of the tricycle, the rubber pad 606 on the limiting frame 605 can abut against the rear side wall. The rubber pad 606 also increases the friction between the limit frame 605 and the rear side wall of the vehicle, which helps prevent the crusher body 1 from being unstable when crushing straw. Next, the clamp frame 501 is placed on the top of the feed hopper 4. Since the clamp frame 501 and the clamp plate 502 are equally spaced, after aligning the two sets of through holes, the limit rod 503 can be threaded into the inside of the clamp frame 501. The diameter of the top of the limit rod 503 is larger than the diameter of its bottom. When the top of the limit rod 503 abuts against the clamp plate 502, the clamp plate 502 can be positioned on the clamp frame 501, and the straw is transported through the feed hopper 4 into the inside of the crusher body 1. After crushing, the straw is sprayed into the tricycle from the side of the crusher body 1 near the baffle 3, thereby reducing the tedious steps for the operator to handle the straw fragments.
