Description

Technical Field

[0001] The invention belongs to the technical field of precision fertilization in agriculture and forestry, and particularly relates to a fertilizer loading work frame for a shoulder fertilizer spreader and a use method thereof. Background Art

[0002] In order to achieve precise fertilization, enterprises in the agricultural and forestry fields have developed a variety of fertilizer applicators. Among them, the backpack fertilizer applicator is particularly suitable for working in mountainous forests with large slopes, and has a particularly broad prospect for promotion and use in the field of forestry fertilization. However, due to the lack of improvement of related peripheral supporting technologies and tools, the promotion and use of the backpack fertilizer applicator is still subject to great restrictions.

[0003] In order to achieve basic fertilization efficiency and based on the general packaging specifications of fertilizer products, operators usually pour a bag of 25kg or even larger fertilizer into the fertilizer applicator when fertilizing. If the fertilizer applicator is placed on the ground, it is difficult for the fertilizer operator to put the strap on his shoulder while squatting on the ground, and the center of gravity is too low, so it is difficult for the fertilizer operator to put the fertilizer applicator on his shoulder and stand up by himself. Based on this situation, people currently use the following two methods to load fertilizer into the fertilizer applicator when using a shoulder-carrying fertilizer applicator: one is that the fertilizer operator stands and puts the fertilizer applicator on his shoulder in advance, and other personnel lift the fertilizer and help pour it into the fertilizer applicator; the other is that the fertilizer operator first places the fertilizer applicator on the ground, pours the fertilizer into the fertilizer applicator, and then lifts the fertilizer applicator to a step. The operator squats down, puts the strap of the fertilizer applicator on his shoulder and carries the fertilizer applicator.

[0004] The above two fertilizer loading methods still have many inconveniences in actual fertilization operations. First, since the fertilizer bag of the fertilizer applicator is soft and has no open and formed bag mouth, the operator needs to tear open and hold the bag mouth with one hand when pouring fertilizer into it, and pour fertilizer with the other hand. The operation efficiency is low and it is very laborious. In addition, it is easy to spill fertilizer outside the fertilizer bag during the operation. Secondly, as in the first operation method, at least two people are required to complete the fertilizer loading, and one person cannot perform the fertilizer loading operation normally; thirdly, after loading the fertilizer into the fertilizer applicator, the fertilizer operator also needs to find a place with appropriate steps, first lift the fertilizer applicator onto the steps, and use the height difference to carry the fertilizer applicator on the shoulder, which is not only laborious but also affects the efficiency of the fertilization operation.

[0005] Therefore, it is necessary to develop an auxiliary tool for loading fertilizer for a shoulder-back fertilizer spreader, so that the fertilizer operator can easily, labor-savingly and quickly complete the loading of the fertilizer spreader by himself anytime and anywhere and carry it on his shoulders and stand up, which is very necessary for the promotion and use of the shoulder-back fertilizer spreader. Summary of the invention
