DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1-Figure 4As shown, the present invention provides a farmland agglomerated soil processing device, comprising a frame 1, wherein the bottom surface of the inner cavity of the frame 1 is sequentially provided with a straight section and an inclined section, and a shovel tooth 19 is installed on the front bottom surface of the straight section of the frame 1, a chain driving unit for conveying agglomerated soil is arranged at the inclined section of the frame 1, and a fixed frame 7 is fixedly connected to the outer wall surface of the frame 1, and a powdered soil chamber 8 for processing the conveyed agglomerated soil is arranged inside the fixed frame 7, and a folding portion 20 is installed between the inlet end of the powdered soil chamber 8 and the top outer wall surface of the frame 1, and the chain driving unit comprises two gears rotatably installed on the inner wall surface of one side of the frame 1, and the two gears are meshed and connected by a chain, and the inner walls on both sides of the frame 1 are provided with a chain. A plurality of chain rods 12 are installed between the chains, and a connecting steel cable 15 is installed between the plurality of chain rods 12. A mounting rod 13 is installed on the surface of at least one chain rod 12, and an intercepting rod 14 for carrying agglomerated soil is fixedly connected to the end of the mounting rod 13. The number of intercepting rods 14 in the present application is multiple, and the number is less than the number of chain rods 12, and they are arranged according to the distance. A cross plate 4 is arranged on the upper part of the straight section of the frame 1, and a fixing part 16 is installed on the top of the front end of the frame 1. A connecting plate 17 is connected to the internal rotation of the fixing part 16, and the end of the connecting plate 17 is fixedly connected to a connecting beam 2, and the end of the connecting beam 2 is fixed to the surface of the tractor, and the middle surface of the connecting beam 2 is hinged to be useful. The hydraulic cylinder 11 is used to push the cross plate 4 to move. When in use, the shovel teeth 19 of the straight section of the frame 1 are inserted into the ground, and the frame 1 and the silt chamber 8 are driven together with the tractor, with low power loss. The soil blocks are shoveled in through the shovel teeth 19. When shoveling in, the direction of the frame 1 is controlled by the hydraulic cylinder 11, that is, the connection between the frame 1 and the connecting plate 17 rotates to change the depth of the shovel teeth 19 entering the soil, that is, to adjust the shoveling depth. Since the frame 1 is in a transmission state, the soil blocks reach the inclined section from the straight section in the frame 1, and then the chain 12 between the two chains moves together through the reciprocating transmission chain, and the chain 12 drives at least one intercepting rod 14 to move. The chain drives the chain rod 12 and its intercepting rod 14 to move, thereby ensuring a good separation effect. The soil or gravel is intercepted by the reciprocating intercepting rod 14 to prevent the soil or gravel from falling when rising. The soil or gravel is transported from the top of the frame 1 to the silt chamber 8. When entering the silt chamber 8, the folding portion 20 between the top of the frame 1 and the side of the silt chamber 8 prevents the soil or gravel from falling out of the silt chamber 8 when following the transmission. When the angle of the frame 1 is changed by the hydraulic cylinder 11, the folding portion 20 is in extension, which can adapt to the use of the frame 1 in different states and meet a variety of usage scenarios.

[0028] See also Figure 1As shown, blocking parts 3 are provided on both sides of the bottom of the front end of the frame 1, and a covering part 5 is provided on the inner wall of the frame 1 above the chain. The blocking parts 3 on both sides prevent the protrusions entering the inner side of the frame 1 from leaking out from the bottom, thereby improving the efficiency of picking up soil. The soil blocks follow the transmission chain rod to rise to the inclined section in the frame 1. During transmission, the covering part 5 protects the outside of the chain to avoid direct contact between the soil blocks and the chain.

[0029] See also Figure 1 and Figure 2 As shown, a mounting portion 10 is installed on the front end surface of the cross plate 4, and a reduction motor is installed on the upper surface of the cross plate 4. The driving end of the reduction motor is connected to a gear through a transmission belt. A shell 6 is provided on the outside of the transmission belt. The shell 6 is fixed to the outer surface of the frame 1. First, the transmission belt drives the top gear to rotate, and then the chain connected to the gear is driven. The transmission belt is protected by the shell 6. The pushing end of the hydraulic cylinder 11 is hinged to the mounting portion 10, and the mounting portion 10 is pushed by the hydraulic cylinder 11, thereby causing the cross plate 4 to move, and the cross plate 4 drives the frame 1 to move as a whole, thereby changing the shoveling depth of the shovel teeth 19 on the frame 1.

[0030] See also Figure 4 As shown, a guide portion 27 is provided on the top front side of the silt chamber 8 and below the top of the inclined section of the frame 1, and two crushing rollers 28 are rotatably installed in the middle of the inner cavity of the silt chamber 8. The two crushing rollers 28 are arranged in close proximity. Soil lumps or gravel rise from the inclined section, and fall between the two crushing rollers 28 under the guidance of the guide portion 27, and are crushed by the crushing rollers 28.

[0031] See also Figure 4 As shown, a discharge port 29 is provided on one side surface of the bottom of the silt chamber 8, a blocking plate 30 is rotatably installed on the top of the inner cavity of the discharge port 29, a cross bar 9 is installed on the bottom of the rear end of the fixed frame 7, a fixing rod 31 is connected to the one side surface of the cross bar 9, and the end of the fixing rod 31 is connected to the blocking plate 30, so that the squeezed and crushed soil or gravel returns to the farmland through the discharge port 29, and when the blocking plate 30 blocks the discharge port 29, it is in a closed state.

[0032] See also Figure 3As shown, the upper surface edge of the fixing frame 7 is hinged with a hydraulic cylinder 26, and the upper surface of the fixing frame 7 is fixed with a protrusion 22, the outer side of the protrusion 22 is hinged with a fitting plate 23, one end of the fitting plate 23 is fixedly connected with a mounting sleeve 24, the pushing end of the hydraulic cylinder 26 is hinged with the U-shaped end surface of the mounting sleeve 24, the outer side of the mounting sleeve 24 is fixedly sleeved with a sleeve frame 25, one end of the sleeve frame 25 is provided with a fixing seat 21, and the fixing seat 21 is fixed to the outer wall surface of the silt chamber 8. When the hydraulic When cylinder 26 is working, that is, hydraulic cylinder 26 pushes the mounting sleeve 24, synchronously driving the fitting plate 23 and the raised portion 22 to rotate. As the rotation base point, since the mounting sleeve 24 is fixedly connected to the sleeve frame 25, the silt chamber 8 connected to the fixed seat 21 is driven to rotate together, that is, the top of the silt chamber 8 rotates toward the rear side around the rotation base point, changing the angle of the silt chamber 8. At this time, the discharge port 29 is separated from the blocking plate 30, that is, the discharge of silt or stone is achieved through the opened discharge port 29.

[0033] When the present invention is in use, two groups of chains are used to drive a plurality of chain rods 12 to move together, which is more durable, and a plurality of reciprocating interception rods 14 are used to intercept soil blocks or gravel to prevent soil blocks or gravel from falling when they are rising. The soil blocks or gravel reach the inclined section from the straight section, and are transported to the silt chamber 8 by the upward movement, and are prevented from falling out of the silt chamber 8 when they follow the transmission through the folding portion 20 between the top of the frame 1 and the side of the silt chamber 8. When the angle of the frame 1 is changed by the hydraulic cylinder 11, the folding portion 20 is in an extended state, which is suitable for the use of the frame 1 in different states and meets a variety of usage scenarios.

[0034] Under the guidance of the guide part 27, the soil blocks or gravel fall between the two crushing rollers 28. When the soil blocks or gravel are squeezed and crushed to be discharged, the hydraulic cylinder 26 pushes the mounting sleeve 24, and synchronously drives the fitting plate 23 and the protruding part 22 to rotate. As the rotation base point, since the mounting sleeve 24 is fixedly connected to the sleeve frame 25, the silt chamber 8 connected to the fixed seat 21 is driven to rotate together, that is, the top of the silt chamber 8 rotates toward the rear side around the rotation base point to change the angle of the silt chamber 8. At this time, the discharge port 29 is separated from the blocking plate 30, that is, the discharge is realized through the opened discharge port 29.
