DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Referring to Figures 1-5 For an embodiment of the utility model, it discloses a kind of automatic seeding machine water filling mechanism, specifically the water filling mechanism includes the water delivery mechanism 2 of installation on conveying line 1 and water receiving tank 3, the water receiving tank 3 is used to recycle the water overflowed by water delivery mechanism 2, to realize the recycling of water, of course the side of water receiving tank 3 can also be communicated with a discharge pipe, water in water receiving tank 3 can be conveniently discharged by the discharge pipe, of course the discharge pipe can also be connected to external water tank, to realize the recycling of water:

[0024] The water receiving tank 3 is below the water delivery mechanism 2, the water receiving tank 3 is connected by tensioning assembly 4 and the frame of conveying line 1, wherein the inside of the water receiving tank 3 is also provided with elastic assembly 5, the top of the elastic assembly 5 is placed with filter plate 6, the frame bottom of conveying line 1 is provided with abutting piece 11 abutting the filter plate 6, the abutting piece 11 in the embodiment can be provided as bolt, i.e. two bolts are threadedly connected at the frame bottom of conveying line 1, when the water receiving tank 3 is moved upward by the action of tensioning assembly 4, the abutting of the filter plate 6 by bolt can make the filter plate 6 move downward, when it is needed to clean the filter plate 6, the water receiving tank 3 is moved downward, under the pushing of elastic assembly 5, the filter plate 6 is moved upward, at this time, the filter plate 6 can be conveniently taken out for cleaning or replacement.

[0025] In some embodiments, the water delivery mechanism 2 in the utility model includes two vertical plates 21 fixedly installed on the frame of the conveying line 1, a plurality of branch pipes 22 are fixedly installed between the two vertical plates 21, and water spraying holes are formed in the bottom of the branch pipes 22.

[0026] A plurality of the branch pipes 22 are commonly connected to a main pipe 23, and the main pipe 23 is used to connect to a water source.

[0027] As a preferred embodiment, a valve and a pressure gauge can also be installed on the main pipe 23, the pressure gauge is used to display water pressure, and the valve is used to control the on-off of the entire water circuit. During the seeding process, when the seedling tray passes through the water delivery mechanism 2 after being covered with soil, the main pipe 23 opens the water circuit, and water is sprayed into the seedling tray through the water spraying holes on the plurality of branch pipes 22, so as to complete the water filling operation of the seedling tray.

[0028] Further, the tension assembly 4 in the embodiment includes a connecting seat 41 fixed on the side of the frame of the conveying line 1, and a U-shaped rod 42 is rotatably connected to the connecting seat 41;

[0029] The side of the water receiving tank 3 is further provided with a fixing seat 43, and an arm rod 44 is rotatably connected to the fixing seat 43. The two ends of the U-shaped rod 42 are rotatably connected to the arm rod 44.

[0030] On the basis of the above embodiment, the middle part of the arm rod 44 is rotatably connected to a rotating shaft 45, and the two ends of the U-shaped rod 42 pass through the two ends of the rotating shaft 45. Two locking nuts 46 are threadedly connected to the outer side of the end of the U-shaped rod 42, and the two locking nuts 46 are clamped on the outer side of the rotating shaft 45.

[0031] That is, the arm rod 44 cooperates with the U-shaped rod 42 to form a lock type tension structure in the utility model. When the water receiving tank 3 needs to be fixed, the arm rod 44 is rotated downward. When the arm rod 44 is rotated to the vertical position, the water receiving tank 3 is driven to displace upward until the abutting part 11 abuts against the filter plate 6 to make the filter plate 6 move downward and press the elastic assembly 5, so that the connection and locking of the water receiving tank 3 are completed.

[0032] Similarly, when the filter plate 6 inside needs to be cleaned and replaced, the arm rod 44 is pushed upward. At this time, the water receiving tank 3 can be moved downward by a small distance by means of the stretching length of the arm rod 44 and the U-shaped rod 42. After moving downward, the filter plate 6 is separated from the abutting part 11 and is popped up. At this time, the filter plate 6 can be taken out for cleaning and replacement. The overall structure is simple. Since the water receiving tank 3 only moves by a small distance when being installed and dismounted, the work efficiency is greatly improved.

[0033] Of course, if the water receiving tank 3 needs to be completely dismounted, the above-mentioned locking nuts 46 are only dismounted to separate the locking nuts 46 from the rotating shaft 45, so that the water receiving tank 3 can be completely taken out.

[0034] In some embodiments, the elastic assembly 5 in the utility model includes four spring telescopic rods 51 fixedly installed in the water receiving tank 3. Specifically, the spring telescopic rod 51 in the embodiment includes a telescopic rod and a spring connected inside the telescopic rod. This structure is a conventional means for the person skilled in the art, and will not be described here. Every two spring telescopic rods 51 form a group, and a bearing plate 52 is installed between the top parts of the two groups. The filter plate 6 is placed above the two bearing plates 52.

[0035] In addition, in order to ensure that the filter plate 6 is limited and supported when the filter plate 6 moves downward, the inner side of the water receiving tank 3 is further provided with a ring frame 31. The filter plate 6 contacts the ring frame 31 when the filter plate 6 moves downward. The middle part of the ring frame 31 is provided with an avoiding opening 32 for avoiding the bearing plate 52.

[0036] That is, when the water receiving tank 3 is fixed to move upward, the abutting piece 11 at the bottom of the conveying line 1 frame will abut to move downward the filter plate 6, which will compress the spring telescopic rod 51 to make it retract, and then, after the water receiving tank 3 is fixed in place, the filter plate 6 is stably supported above the ring frame 31, thus improving the installation stability of the filter plate 6.

[0037] In summary, in the utility model, the water receiving tank 3 is movable, the filter plate 6 inside the water receiving tank 3 filters the soil in the dripping water, and of course, after a long time of filtering, the water receiving tank 3 can be controlled to move a small distance downward by opening the tensioning assembly 4, at which time the filter plate 6 can be easily taken out for replacement and cleaning. Since the water receiving tank 3 only moves a small distance when being installed and disassembled, the work efficiency is greatly improved.

[0038] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
