Technical field

The invention relates to the technical field of agricultural production, and in particular to a seedling root fertilization device suitable for hole fertilization.

Background technique

At present, there are many projects in farmland operations, such as sowing, fertilizing, weeding, harvesting, etc. In agricultural production, fertilization is a very important link. Various fertilizers are often used. Different types of fertilizers need to be spread in different amounts. In order to meet the absorption of different nutrients by crops, the hole fertilization method is a common method of fertilizing seedlings. The hole fertilization method is to dig trenches or holes in the soil and apply fertilizer to crops suitable for on-demand sowing. , usually you need to dig a trench first, then spread the fertilizer into the trench, and then cover the fertilizer with soil. This requires the cooperation of multiple people. One person needs to dig the trench, one person applies fertilizer, and one person needs to cover the soil back. , which makes fertilization very time-consuming, laborious, and inefficient;

There are usually two categories of organic fertilizers and inorganic fertilizers used when fertilizing. Inorganic fertilizers are mineral fertilizers, also called chemical fertilizers. Inorganic fertilizers refer to fertilizers produced by chemical synthesis methods. Inorganic fertilizers are mostly granular; organic fertilizers are those produced by farmers. Fertilizer. Organic fertilizer not only contains large amounts of elements and trace elements needed by plants, but also rich organic nutrients. Organic fertilizers are often in irregular lumps of different sizes due to fermentation and composting. Therefore, when using organic fertilizers, due to The organic fertilizer is in the shape of irregular blocks of different sizes, which makes it easy to accumulate when falling, causing blockage and interrupting the fall of the fertilizer.

There is no need to set up an additional power source, thus saving power costs.

The overall working process and principle of the above-mentioned Embodiment 1 to Embodiment 3 are as follows:

When carrying out hole fertilization, the base 1 is installed on the rear of the tractor through the drawbar 13, and the tractor pulls the base 1 forward. During the forward movement of the base 1, the furrow plow 2 opens a ditch on the ground. First, the trenching depth of the furrowing plow 2 can be adjusted according to the fertilization requirements. When adjusting the furrowing plow 2, take out the fixing pin 19 from the positioning hole 18, and then pull the connecting rod 16 vertically to move vertically in the sleeve 17, and pass The connecting rod 16 drives the furrow plow 2 to rise or fall vertically, and then insert the fixing pin 19 into the sleeve 17 and the positioning hole 18 in sequence, so that the furrow plow 2 can be fixed, thereby changing the relationship between the furrow plow 2 and the ground. distance, so that trenches of different depths can be excavated. After the trench is opened, the fertilizer drops from the first storage box 4 or the second storage box 5 into the trench, and then is pushed into the trench through the soil covering tray 3 The pushed soil covers the soil back into the soil trench, thereby covering the fertilizer in the soil trench, which not only reduces the number of workers and saves human resources, but also improves the efficiency of fertilization;

When using irregular block organic fertilizer, put the block organic fertilizer into the first storage tank 4, and use the tractor to pull the base 1 to move forward. During the forward movement of the base 1, the furrow plow 2 is on the ground. A trench is opened. When the base 1 moves forward, the driving wheel 11 rolls along the ground. The rolling driving wheel 11 drives the transmission shaft 10 to rotate synchronously. The rotating transmission shaft 10 drives the first driving wheel 65 to rotate. The first driving wheel 65 drives the conveyor chain 61 to rotate vertically on the support frame 63, and the conveyor chain 61 drives the hopper 62 to rotate synchronously on the support frame 63, so that the hopper 62 close to the first storage tank 4 moves from the first storage tank 4 The bottom moves vertically toward the top. During the vertical movement of the hopper 62, the hopper 62 shovels out the massive organic fertilizer in the first storage tank 4, and the organic fertilizer is removed from the top opening of the first storage tank 4 through the hopper 62. Shovel out, the hopper 62 containing organic fertilizer rotates to the top of the support frame 63, the organic fertilizer in the hopper 62 is flipped into the protective cover 7, and the organic fertilizer falls along the gap between the protective cover 7 and the support frame 63, so that the organic fertilizer falls into the soil trench, and then during the forward movement of the base 1, the soil at the top of the soil trench is covered back into the soil trench through the soil covering plate 3, so that the soil can cover the organic fertilizer, so that the irregular lumps of organic fertilizer can be Falling into the soil ditch can reduce the problem of organic fertilizer blocking the falling channel and causing interruption of fertilization;

When using granular inorganic fertilizer, put the inorganic fertilizer into the second storage tank 5, and the tractor pulls the base 1 to move forward. During the forward movement of the base 1, the furrow plow 2 opens a ditch on the ground. 1. During the forward movement, the driving wheel 11 rolls along the ground. The rolling driving wheel 11 drives the transmission shaft 10 to rotate synchronously. The rotating transmission shaft 10 drives the second driving wheel 94 to rotate. The rotating second driving wheel 94 passes through The transmission chain 95 drives the second driven wheel 93 to rotate, and the rotating second driven wheel 93 drives the rotating shaft 91 to rotate at the bottom of the second storage tank 5. During the rotation of the rotating shaft 91, the placing groove 92 rotates synchronously, and the placing groove 92 rotates During the process, when the placement groove 92 rotates to the upward position, the granular inorganic fertilizer continues to fall into the placement groove 92, and then when the placement groove 92 containing the inorganic fertilizer rotates to the downward position, the inorganic fertilizer in the placement groove 92 falls to In the conveying pipe 12, the inorganic fertilizer slides down into the ditch through the conveying pipe 12 under the action of gravity.
