DETAILED DESCRIPTION

[0027] First embodiment

[0028] A density-adjustable grass silage fermentation device mainly consists of two parts, a grass density adjustment mechanism and a grass fermentation storage mechanism 5. The grass density adjustment mechanism is used to change the compression density of the grass. The compressed grass is placed in the grass fermentation storage mechanism and taken out after a period of time to observe the effect of the grass density on the silage quality.

[0029] The forage density adjustment mechanism comprises a bottom plate 11, on which a plurality of supporting rods 12 are arranged, and a center plate 13 is arranged at the upper ends of the supporting rods, and a center hole (not shown) is arranged in the middle of the center plate.

[0030] A compression tube 2 is installed in the central hole.

[0031] Furthermore, the compression tube 2 comprises a compression tube body 21, which is slightly smaller than the diameter of the center hole. A limiting ring 22 is provided on the compression tube body, and the diameter of the limiting ring is larger than the diameter of the center hole.

[0032] An upper connecting rod 14 is provided on both sides of the center plate, an upper fixing plate 15 is installed on the top of the upper connecting rod, a threaded hole is provided in the middle of the upper fixing plate, a screw rod 32 is rotatably installed in the threaded hole, a rotating rod 33 is provided at the upper end of the screw rod, and a compression mechanism 3 is provided at the lower end of the screw rod for squeezing the forage placed in the compression tube.

[0033] To be more specific, the compression mechanism is a compression column 31 .

[0034] The compression column is caused to move spirally by rotating the rotating rod, thereby squeezing the grass to achieve volume compression of the grass and density change.

[0035] A pull-down mechanism 4 is provided at the lower side of the center plate. The pull-down mechanism is used to block the lower pipe opening of the compression pipe and facilitate the discharge of grass at the lower pipe opening.

[0036] The pull-down mechanism includes a left support plate 41 and a right support plate 42 respectively arranged on both sides of the center plate, and a pull-down plate 43 is slidably installed between the left support plate and the right support plate, wherein the pull-down plate is provided with a left guide groove 44 and a right guide groove 45, the left guide groove cooperates with the left support plate, and the right guide groove cooperates with the right support plate. A middle groove 46 is provided in the middle of the pull-down plate, and the width of the middle groove is greater than the diameter of the compression tube 2. When the pull-down plate is inserted to the lower side of the center plate, the lower tube opening of the compression tube is in the middle groove, so that the pull-down plate can close the lower tube opening to prevent grass from leaking from there.

[0037] The forage fermentation storage mechanism 5 comprises an outer barrel 51, the inner wall of which is provided with an inner thread, and the inner barrel cover 52 is connected to the inner thread of the outer barrel. Figure 3 and Figure 6 As shown, a vent hole 54 is provided at the center of the inner barrel cover, and a plurality of rotating locking grooves 53 in an annular array are provided on the inner barrel cover.

[0038] A one-way valve 56 is installed in the air vent.

[0039] Furthermore, a sealing rubber ring 55 is provided between the one-way valve and the air vent.

[0040] A date adjustment disk 57 is also installed outside the air vent to record the fermentation time of the grass.

[0041] The rotational locking groove cooperates with the locking wrench 6. The inner barrel cover can be spirally rotated downward by the locking wrench to discharge the air in the outer barrel from the one-way valve.

[0042] like Figure 7As shown, the locking wrench 6 comprises a telescopic rod set, a connecting rod 61 is provided at the lower end of the telescopic rod set, a locking block 62 is provided on the connecting rod, and a handle 66 is provided at the upper end of the telescopic rod set. First, the locking block is inserted into the rotation locking groove, and then the handle is rotated to rotate the inner barrel cover along the internal thread on the inner wall of the outer barrel, so that the air in the outer barrel is discharged from the one-way valve.

[0043] Furthermore, the telescopic rod assembly includes an outer telescopic tube 63, an inner rod 64 and an adjusting knob 65, wherein the inner rod is slidably installed in the outer telescopic tube, and the adjusting knob can make the inner rod move along the outer telescopic tube and be positioned at a point on the outer telescopic tube.

[0044] Second embodiment

[0045] like Figure 5 As shown, the difference from the first embodiment is that the grass density adjustment mechanism and the grass fermentation storage mechanism 5 are combined into an integrated structure.

[0046] The center plate is connected to a side plate 71, and a conveyor mechanism is provided between the bottom plate and the center plate, on which an outer barrel 51 is placed. A push mechanism is provided on one side of the conveyor mechanism, which can push the outer barrel to the lower side of one side plate, and a positioning wrench 6 is installed on the side plate.

[0047] The side panels are rotatably connected to the center panel, so that the side panels can be folded when the device is not in use.

[0048] Furthermore, the conveyor belt mechanism includes an active roller 74, a driven roller 76 and a conveyor belt 75 connecting the two rollers. The active roller is connected to a motor. The motor drives the active roller to rotate, thereby driving the conveyor belt to move, so that the outer barrel moves to the bottom of the compression tube, so that the compressed forage can be directly moved to the next process for exhaust and fermentation.

[0049] Furthermore, the pushing mechanism includes an electric cylinder 72 and a push plate 73. The electric cylinder is connected to a push plate.

[0050] Working principle: The device consists of two parts: a grass density adjustment mechanism and a grass fermentation storage mechanism. The grass density adjustment mechanism is used to produce grass of different densities, which is then placed in the grass fermentation storage mechanism for anaerobic fermentation.

[0051] The compression tube is a 15 cm diameter transparent plastic straight cylinder with scale. The crushed forage raw materials are added to the compression tube, and the compression height is calculated according to the amount and density of the feed to be fermented. 4 and 2 are connected by a slot. 2 is divided into two types, one is a flat plate (without holes) at the bottom, which is used to make compressed feed; the other is a hole with the same diameter as 4, which is used to discharge the compressed feed (similar to compressed cake) out of the 4 straight tube. The pull-down plate can block or not block the lower tube mouth of the compression tube. When blocked, it is used to make compressed feed; when not blocked, it is used to discharge the compressed feed out of the compression tube. The compressed feed is rotated to different heights by the rotating rod 33, and forage feed of different densities can be obtained. Pull the pull-down plate so that the pull-down plate cannot block the compression tube, and continue to rotate the rotating rod 33 to discharge the compressed feed. The compressed feed is then placed in an outer barrel, the diameter of the outer barrel is the same as that of the compression tube, and the inner barrel has threads. Use a positioning wrench to connect the inner barrel cover, and rotate the handle 66 to compress the inner barrel cover to press the feed. Then remove the positioning wrench. There is an exhaust valve in the middle of the inner barrel cover (only exhaust but not intake) to ensure an anaerobic environment. After a certain period of fermentation, use the wrench to open the inner barrel cover again and take samples.

[0052] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
