Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of earthworm farming equipment, and in particular relates to an earthworm farming bed manure spreading machine. Background Technology
[0002] Earthworms have high medicinal and economic value. Most of the nutrients they consume during their growth come from the excrement of other animals. Moreover, earthworm excrement is rich in nutrients such as nitrogen, phosphorus, and potassium, making it valuable for environmental protection and agricultural production.
[0003] The Daping No. 2 earthworm is a relatively common earthworm species. Before earthworm farming, a substrate bed made of manure needs to be laid at the farming location to provide a suitable living environment for the earthworms. During the farming process, water needs to be poured onto the substrate bed to maintain its moisture. Most existing substrate beds have an arched cross-section. When watering the substrate bed, the top is more likely to come into contact with water, which is more conducive to earthworm growth than the sides of the substrate bed. Most earthworms will usually gather at the top of the arched bed to find a more comfortable position. However, this results in a higher density of earthworms in some parts of the substrate bed, which is not conducive to the disposal of manure in other parts of the substrate bed, and is also not conducive to earthworm growth. Utility Model Content
[0004] In view of this, the present invention aims to propose a manure spreading machine for earthworm breeding beds, which can shape the bed while laying it, so as to facilitate a more even distribution of earthworms on the bed.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A manure-spreading machine for earthworm farming beds, including
[0007] The hopper, which can move along the length of the base bed, has a storage cavity at its bottom. The storage cavity extends into a discharge section on one side of the hopper. The storage cavity is equipped with spiral blades, and the axial direction of the spiral blades is arranged along the direction from the hopper to the storage cavity, so that the material in the storage cavity can be sent to the discharge section. The bottom surface of the discharge section has multiple discharge holes, which are strip-shaped, and a baffle is left between each pair of adjacent discharge holes.
[0008] The shaping unit includes a scraper, and one side edge of the scraper forms an angle with the length direction of the base bed, and the side edge can move in the vertical direction.
[0009] Furthermore, the length direction of the discharge hole is parallel to the length direction of the spiral blade.
[0010] Furthermore, the length of the discharge hole is the same as the length of the baffle.
[0011] Furthermore, side plates extend outward from both sides of the scraper, and the two side plates and the scraper surround each other to form a trapezoidal structure with an opening at the bottom.
[0012] Furthermore, a control section extends outward from one side of the scraper, and the scraper can rotate around one edge of the control section. The other edge of the control section is hinged to the piston rod of a hydraulic cylinder.
[0013] Furthermore, the control unit is perpendicular to the scraper, and a reinforcing rib is provided between the control unit and the scraper.
[0014] Furthermore, the hopper is provided with a soil loosening module on the side away from the scraper, which includes a rotating shaft that can move in the vertical direction, and multiple rotary tillage blades are fixed on the rotating shaft along the length direction.
[0015] Furthermore, the rotating shaft is rotatably connected to a tiller frame, which can rotate around the end of itself away from the rotating shaft.
[0016] Furthermore, the middle part of the tiller frame is hinged to the piston rod of a hydraulic cylinder, and the cylinder body of the hydraulic cylinder is hinged to the material dropping part on one side of the hopper.
[0017] Compared with existing technologies, the earthworm breeding bed manure spreading machine described in this utility model has the following advantages:
[0018] This utility model adopts a method of opening a long strip-shaped discharge hole below the material discharge section, and setting a baffle between the two discharge holes to prevent the material in the material discharge section from falling immediately when it reaches the discharge hole, thereby increasing the width of the material discharge. At the same time, in conjunction with the scraper, the top of the material is scraped flat after falling, thereby increasing the top area of the base bed, so that there is more suitable space for earthworms to survive when watering the base bed and placing earthworms.
[0019] The structure of two side plates and scraper edge forming a trapezoidal shape makes the cross section of the subgrade also trapezoidal after the scraper passes, making the subgrade structure more stable and preventing the subgrade sides from collapsing.
[0020] By using rotary tillers in front of the hopper, the soil is loosened before the manure is spread, preventing the bed from being loose at the top and dense at the bottom, thus ensuring a good environment for earthworm growth and reproduction. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] The earthworm breeding bed manure distribution machine of this utility model includes a hopper 1, a shaping unit 2, and a loosening unit. The hopper 1 is funnel-shaped, with a storage cavity 11 at the bottom. A discharge section 12 extends outward from the bottom of the storage cavity 11. In this embodiment, the line connecting the discharge section 12 and the hopper 1 is perpendicular to the length direction of the bed to be laid. During the bed setting process, the discharge section 12 is placed directly above the bed. The discharge cavity has at least one spiral blade 15, and the axial direction of the spiral blade 15 is arranged along the hopper 1 towards the storage cavity 11, so that the material in the storage cavity 11 can be sent to the discharge section 12. The bottom surface of the discharge section 12 has multiple discharge holes 13, which are strip-shaped, and a baffle 14 is left between each pair of adjacent discharge holes 13. In this embodiment, there are three spiral blades 15, thereby improving the efficiency of transporting manure in the hopper 1 towards the discharge holes 13. The length direction of the discharge hole 13 is parallel to the length direction of the spiral blade 15. The length of the discharge hole 13 is the same as the length of the baffle 14, so that the fermented manure can move along the spiral blade 15 toward the discharge hole 13. At the same time, since some of the manure is in block form, the baffle 14 prevents the manure from falling after it reaches the discharge hole. Instead, it continues to move along the discharge hole with the spiral blade 15 until the space where the discharge hole is located is filled. As the spiral blade 15 continues to rotate, the manure is squeezed, and large pieces of manure are broken up. Then, the manure falls from the discharge hole and accumulates to form a bed.
[0032] The shaping unit 2 includes a scraper 21, and one edge of the scraper 21 forms an angle with the length direction of the bed, and this edge can move vertically. In this embodiment, the angle between the length direction of the bed and the edge of the scraper 21 is 90°. Optionally, those skilled in the art can also, as needed, move the side of the scraper 21 near the top of the bed toward the hopper 1 so that the excrement on the bed can be scraped flat, so that earthworms can obtain more comfortable living space. In this embodiment, side plates 22 extend outward from both sides of the scraper 21, and the two side plates 22 and the scraper 21 surround to form a trapezoidal structure with an open bottom. The base bed is shaped by the hanging plate and side plate 22, making its cross-section trapezoidal. This results in a flatter top, preventing water from flowing down the sides after watering and allowing for longer contact between the top of the base bed and water during subsequent watering. This increases the surface area in contact with water, creating a more suitable environment for earthworms and allowing them to be more evenly distributed on the top of the base bed. A control section 211 extends outward from one side of the scraper 21, and the scraper 21 can rotate around one edge of the control section 211. The other edge of the control section 211 is hinged to the piston rod of the first hydraulic cylinder 23. In this embodiment, the cylinder body of the first hydraulic cylinder 23 is fixed to the housing of the material discharge section 12. The top of the housing of the material discharge section 12 forms a platform structure. The pump, hydraulic oil tank, and other equipment driving the first hydraulic cylinder 23 can be fixed to the platform or installed on a mobile platform carrying a manure spreader, such as a tractor or a flatbed cart. To facilitate the movement of the scraper 21 via the control unit 211, the control unit 211 is perpendicular to the scraper 21, and a reinforcing rib 24 is provided between the control unit 211 and the scraper 21.
[0033] The hopper 1, on the side away from the scraper 21, is also equipped with a soil loosening module 3, which includes a rotating shaft capable of vertical movement. Multiple rotary tillers 31 are fixed along the length of the rotating shaft. More specifically, the rotating shaft is rotatably connected to a tiller frame 32, which can rotate around its end away from the rotating shaft. Specifically, the end of the tiller frame 32 away from the rotating shaft is hinged to the outer shell of the hopper 1 or to a platform (not shown in the figure) fixed to the hopper 1. The rotary tiller frame 31 is rotatably connected to the tiller frame 32 via the rotating shaft. The tiller frame 32 is frame-shaped, with a crossbeam 33 in its middle. The middle of the tiller frame 32 is hinged to the piston rod of a second hydraulic cylinder 34. The cylinder body of the hydraulic cylinder is hinged to the material discharge section 12 on one side of the hopper 1, and the end of the piston rod of the second hydraulic cylinder 34 is hinged to the crossbeam 33. In this embodiment, a sprocket is fixed at one end of the rotating shaft of the rotary tiller 31. Those skilled in the art can drive the chain to rotate the rotary tiller 31 by an engine or electric motor, so that the rotary tiller 31 can loosen the soil while moving.
[0034] Those skilled in the art will understand that the two ends of the rotating shaft of the spiral blade 15 can be rotatably connected to the outer shell of the hopper 1. A gear, pulley, or sprocket can be fixed at one end of the rotating shaft of the spiral blade 15. A motor or engine serves as the power source, and power is transmitted to the rotating shaft of the spiral blade 15 through a transmission system. The motor or engine can be fixed to the outer shell of the hopper 1 or to a carrier such as a tractor. The manure-spreading machine of this invention can, as needed, have wheels installed below the hopper 1 for easy movement, or can be placed directly on a movable carrier for operation.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
