Description

Technical Field

[0001] The invention relates to the technical field of aquatic plant planting, and in particular to an aquatic plant planting device suitable for shrimp and crab ponds. Background Art

[0002] For shrimp and crab breeding ponds, it is very important to choose the right type of aquatic plants. It is usually recommended to use local aquatic plants that are highly adaptable and easy to manage, such as Elodea, Vallisneria, and Hydrilla verticillata. Elodea, also known as the invincible food, is the most well-known aquatic plant among shrimp and crab farmers. Its main characteristics are crisp stems and leaves, fear of heat and cold resistance, vigorous growth and high yield. It can be planted above 0℃ and grows rapidly as the temperature gradually rises.

[0003] Elodea is usually transplanted into shrimp and crab ponds. The transplanting method of Elodea is as follows: first cut the grass into stems of about 15 cm, and insert them into the mud pond like transplanting rice seedlings. The spacing between rows and plants is 20-30 cm, and a 3-5 meter blank area should be reserved to provide shrimp with activity space in the future and to enhance water fluidity. In the initial stage of planting, the water level in the pond should be maintained at 30-40 cm, and the water level can be slowly deepened after the aquatic plants grow gradually vigorously.

[0004] The existing Elodea planting device is similar to a rice transplanter. Although it can complete the automated planting of Elodea, the planting spacing of the planting device is fixed and cannot be adaptively adjusted according to the plant spacing requirements of Elodea planting. Different types of shrimps and crabs have slightly different activity space requirements. When it is necessary to change the plant spacing of Elodea planting, it is necessary to make large adjustments to the device, which is not convenient to use. In addition, the planting device mostly uses a rod pressure method to push the Elodea downward. This hard direct pressure contact method will cause compressive damage to the contacted Elodea, which is not conducive to ensuring the survival rate of the Elodea, and further cannot ensure the overall planting quality of the Elodea.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The algae insertion mechanism 4 includes a plurality of mounting plates 45 corresponding to each seedling placing slot frame 33 and arranged on the front sides of the left and right side vertical plates 1. A seedling clamping assembly 42 for grabbing the Elodea seedlings is arranged on the left side of the mounting plate 45. The seedling clamping assembly 42 includes a bent swing arm 422. A connecting arm 47 is hinged at the front end of the swing arm 422. The end of the connecting arm 47 away from the swing arm 422 is hinged on the mounting plate 45. A connecting pin 48 extending to the inside of the swing arm 422 is rotatably connected to the middle part of the swing arm 422. The right end of the connecting pin 48 is fixedly connected to the swing arm 49.

[0039] During specific operation, the mounting frame 312 is controlled by an electric push rod 315 to drive each sliding plate 313 to slide back and forth in the seedling placing trough frame 33. When the sliding plate 313 moves to the lower end of the seedling placing trough frame 33, the pushing thorn 3131 pierces the seedling gap of the Elodea seedlings, and the Elodea seedlings are driven to move downward synchronously by the resistance effect of the pushing thorn 3131.

Then the swing arm 422 continues to move along the curved trajectory, the notch 4253 is staggered with the tilting arm 4252, and the tilting arm 4252 is pressed by the pressure plate 4254. The tilting arm 4252 lifts the ejection column 424 to compress the spring 4251.

In the synchronous state, the rotating shaft 324 is driven to rotate by another synchronous belt, so that the transverse movement component 32 controls the seedling placing trough frame 33 to produce a transverse movement. The synchronous movement of the two components ensures the balance of seedling picking and planting.

[0054] When in use: S1: first, the Elodea seedlings are neatly placed in each seedling placing trough frame 33, and the Elodea seedlings are placed and limited by the blocking rod 35 so that the Elodea seedlings are vertically distributed on the seedling placing trough frame 33, and then the motor 44 is started, and is connected to the traction plate 5 through an external traction device, so that the traction device pulls the entire device to move in the planting mud of the Elodea seedlings, and the mud wheel 2 cooperates with the traction device to move.

[0055] S2: When the whole device moves forward, the motor 44 drives the linkage shaft 43 to rotate, and the linkage shaft 43 drives each connecting sleeve 46 to rotate. The connecting sleeve 46 drives the swing arm 49 to rotate through the synchronous belt. In the synchronous state, the rotating shaft 324 is driven to rotate by another synchronous belt.

[0056] S3: The bevel gear 1 325 is driven to rotate by the rotating shaft 324, and the bevel gear 1 325 drives the bevel gear 2 326 to rotate and control the rotating rod to drive the rocking plate 321 to rotate, and the rocking plate 321 drives the connecting plate 2 323 to move back and forth horizontally through the rotating pin, so as to change the position of the seedling placing trough frame 33 facing the seedling clamping assembly 42. At the same time, the swing arm 422 is controlled to perform reciprocating curved motion by the rotation of the swing arm 49. When the clamping claw 423 passes through the lower seedling opening 331 of the seedling placing trough frame 33, multiple Elodea seedlings are clamped through the gap. Then, the swing arm 422 continues to move along the curved trajectory, inserts the Elodea seedlings into the mud during the movement, and then, the swing arm 422 moves to the lowest point of the curved trajectory. When the notch 4253 of the pressure plate 4254 corresponds to the tilting arm 4252, the tilting arm 4252 loses the pressure of the pressure plate 4254, and under the rebound action of the spring 4251, the ejection column 424 is controlled to move downward, and the Elodea seedlings clamped in the gap are pushed out of the gap, and then the swing arm 422 continues to move along the curved trajectory, and the clamping claw 423 and the Elodea seedlings inserted into the mud are separated. After the notch 4253 and the tilting arm 4252 are staggered, the pressure plate 4254 presses the tilting arm 4252, and the tilting arm 4252 lifts the ejection column 424 to compress the spring 4251, and resets the position of the ejection column 424. When the swing arm 422 continues to move to the highest point of the curved trajectory, the next seedling clamping action is repeated.

[0057] S4: When the planting spacing of two rows of Elodea seedlings needs to be adjusted, the seedling placing trough frame 33 connected to it on one side is driven to move along the slide bar 2 364 by the electric push rod 2 363, and the seedling placing trough frame 33 except the middle position is driven to move synchronously by the linkage action of each long connecting arm 1 362 and each short connecting arm 1 361, so as to adjust the spacing between two adjacent seedling placing trough frames 33. At the same time, the mounting seat 414 connected to it on one side is driven to move along the guide rod 415 by the electric push rod 3 411, and the mounting seat 414 except the middle position is driven to move synchronously by the linkage action of each long connecting arm 2 412 and each short connecting arm 2 413, so as to adjust the spacing between two adjacent mounting seats 414.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
