The invention relates to an agricultural mechanical silkworm breeding chamber with a high survival rate. The agricultural mechanical silkworm breeding chamber comprises a silkworm breeding chamber, a water tank, a support board, a partition wall and a second roll shaft, the partition wall is installed in the center of the interior of the silkworm breeding chamber, a small silkworm placing chamber is arranged on the one side of the partition wall in the silkworm breeding chamber, a big silkworm placing chamber is arranged on the side, away from the small silkworm breeding chamber, of the partition wall in the silkworm breeding chamber, fixing boards are installed in the centers of the tops of the big silkworm placing chamber and the small silkworm placing chamber respectively, draught fans are arranged in the centers of the bottoms of the fixing boards, water distributors are arranged on the portions, on the outer sides of the draught fans, of the bottoms of the fixing boards, heat collection shell bodies are installed on the portions, over a conveying shell body, of the two side walls of the partition wall respectively, heater strips are fixed to the interiors of the heat collection shell bodies, and silkworm breeding chamber door bodies are connected to the partition wall and the outer side walls of the small silkworm placing chamber and the big silkworm placing chamber in a hinged mode respectively. By means of the agricultural mechanical silkworm breeding chamber, not only are the degree of convenience of replacement between silkworm breeding chambers and the survival rate of silkworm breeding of the silkworm breeding chamber improved, but also the humidity uniformity of the interior of the silkworm breeding chamber is achieved.
